[PMID: 40328155 DOI: 10.1016/j.bioorg.2025.108503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2025] [Revised: 04/16/2025] [Accepted: 04/20/2025] [Indexed: 05/08/2025]
Abstract
Receptor-interacting protein kinase 3 (RIPK3), a key regulator of necroptosis, has emerged as an important target for therapeutic intervention. Flavonoids are natural compounds known for their anti-inflammatory and antioxidant properties, with recent studies highlighting their potential to modulate necroptosis. In this study, we explored the potential of RIPK3 as a target for flavonoids to achieve anti-necroptosis and anti-inflammatory effects. A library of 63 flavonoids was tested for RIPK3 binding and kinase inhibition using fluorescence polarization (FP) competition assay and ADP-Glo kinase activity assay. Six flavonoids, including scutellarein, robinetin, baicalin, myricetin, baicalein, and tricetin, showed significant inhibition of RIPK3, with IC50 values ranging from 2.5 to 13.7 μM. Structural studies of tricetin and robinetin through co-crystallization and molecular docking revealed distinct binding modes of these flavonoids within the ATP-binding pocket of RIPK3. The anti-necroptosis effects of these flavonoids were further evaluated in human HT-29 cells and mouse embryonic fibroblasts (MEFs) using a TSZ-induced cell death assay, resulting in EC50 values in the tens of micromolar range. Western blot analysis demonstrated that these flavonoids inhibit the phosphorylation of RIPK3 and its downstream effector, mixed lineage kinase domain-like protein (MLKL), and disrupt the formation of RIPK1 and RIPK3 aggregates in the necroptosis pathway. These findings identify RIPK3 as a target of natural flavonoids for the first time and elucidate the molecular mechanism underlying the anti-necroptotic activity of these flavonoids.

Abstract
Natural flavonoids may be utilized as an important therapy for cardiovascular diseases (CVDs) caused by intestinal barrier damage. More research is being conducted on the protective properties of natural flavonoids against intestinal barrier injury, although the underlying processes remain unknown. Thus, the purpose of this article is to present current research on natural flavonoids to reduce the incidence of CVDs by protecting intestinal barrier injury, with a particular emphasis on intestinal epithelial barrier integrity (inhibiting oxidative stress, regulating inflammatory cytokine expression, and increasing tight junction protein expression). Furthermore, the mechanisms driving intestinal barrier injury development are briefly explored, as well as natural flavonoids having CVD-protective actions on the intestinal barrier. In addition, natural flavonoids with myocardial protective effects were docked with ZO-1 targets to find natural products with higher activity. These natural flavonoids can improve intestinal mechanical barrier function through anti-oxidant or anti-inflammatory mechanism, and then prevent the occurrence and development of CVDs.

Abstract
Ulcerative colitis (UC) is a non‑specific inflammatory bowel disease characterized by inflammation of the colonic and rectal mucosa and submucosa and has a globally increasing incidence. A compromised intestinal epithelial barrier function has been established as the primary etiological factor in UC, with necroptosis of intestinal epithelial cells exacerbating barrier disruption. Consequently, the inhibition of necroptosis in these cells has the potential to ameliorate colitis severity and preserve intestinal integrity, thereby offering a promising therapeutic approach for UC management. Pristimerin, a naturally occurring pentacyclic triterpenoid derived from Tripterygium wilfordii Hook.f., has been used in the treatment of various diseases. Although pristimerin has been documented to have therapeutic effects on UC, there is a lack of studies exploring its mechanism of action via necroptosis. The present study aimed to elucidate the role of pristimerin in the treatment of UC by examining its inhibitory effects on necroptosis through both in vivo and in vitro experimental approaches. Pristimerin was found to markedly enhance body weight, colon length and intestinal barrier function, while concurrently reducing fecal blood loss in murine models of colitis. Furthermore, both in vivo and in vitro, pristimerin effectively inhibited the phosphorylation of key necroptosis mediators, including receptor‑interacting protein kinase 1, receptor‑interacting protein kinase 3 and mixed lineage kinase domain‑like protein. These findings collectively suggested that the therapeutic effects of pristimerin in UC may be attributed, at least in part, to its ability to suppress necroptosis, thereby improving intestinal barrier integrity.

Abstract
Necroptosis, a distinctive form of programmed cell death differs mechanistically from apoptosis pyroptosis, and autophagy, is characterized by the activation of receptor-interacting protein kinases (RIPK1/RIPK3) and their downstream effector, mixed lineage kinase domain-like protein (MLKL). This programmed cell death pathway serves as a crucial mediator of inflammatory responses and has been implicated in the pathogenesis of diverse pathological conditions. Recent evidence has implicated dysregulated necroptosis in the pathogenesis of severe pregnancy complications, including preeclampsia (PE), fetal growth restriction (FGR), recurrent spontaneous abortion (RSA), and gestational diabetes mellitus (GDM). In these disorders, necroptosis promotes placental dysfunction through multiple interconnected mechanisms: amplification of pro-inflammatory cytokine cascades, aberrant immune activation, disruption of plasma membrane integrity, and subsequent tissue injury.These pregnancy-related pathologies consistently demonstrate elevated necroptotic signatures, correlating with adverse maternal-fetal outcomes. This comprehensive review synthesizes current understanding of the molecular mechanisms underlying necroptosis, with particular emphasis on its pivotal role in the etiopathogenesis of pregnancy-related disorders. Furthermore, we critically evaluate the therapeutic potential of targeting the necroptotic signaling axis, providing novel perspectives for developing targeted interventions to improve clinical outcomes in complicated pregnancies.

Abstract
Doxorubicin (DOX), from the anthracycline family, is a widely utilized chemotherapy for various malignancies; however, its utility is limited due to the serious adverse reactions, particularly on the kidneys, primarily related to oxidative stress, inflammation, and apoptosis. Hesperetin (HES), the citrus fruit derivative, is a naturally occurring flavonoid. Previous studies underscored HES's protective efficacy against renal damage in several disorders in rodents through its proven antioxidant, antiapoptotic, and anti-inflammatory properties. This work explored the protecting role of HES against the nephrotoxic effects of DOX and the possible underlying mechanisms. Nephrotoxicity was induced in rats via administering six equal doses of DOX (3 mg/kg/week, i.p) for six consecutive weeks. The treated group received HES (50 mg/kg/day, p.o.) simultaneously with DOX. Rats' body and kidney weights, serum creatinine, blood urea nitrogen (BUN), and albumin were estimated. Kidney tissue was treated to assess redox status, histopathological, and immunohistochemical alterations. Compared to the controls, coadministration of HES with DOX significantly reduced the serum BUN and creatinine, elevated the serum albumin, amended the glomerular distortion and tubular epithelial degeneration, decreased collagen deposition, vascular congestion, and inflammatory cells in addition to the significant attenuation of inflammatory cytokines and proapoptotic markers. Our study is the first of its kind to underscore the HES's antioxidant, antiapoptotic, and anti-inflammatory activities in an experimental model of DOX-induced nephrotoxicity with emphasis on TNF-α, IL-1β, and IL-6 signaling pathway, rendering it as an effective therapeutic supplement that could alleviate the nephrotoxic effect of DOX.

Abstract
BACKGROUND Sepsis is a life-threatening condition that is characterized by systemic inflammation and organ dysfunction, with adrenal dysfunction being a significant complication. This study aimed to investigate the role of necroptosis and hydrogen sulfide (H2S) in sepsis-induced adrenal dysfunction. METHODS A cecal ligation and puncture (CLP)-induced sepsis mouse model was employed. Adrenocortical-specific mixed lineage kinase domain-like pseudokinase (MLKL) knockout (MLKL-KO) and cystathioneine β-synthase (CBS) knockout (CBS-KO) mice were generated using Cre-loxP technology and adrenocortical-specific Cre tool mice. In vitro experiments utilized TNFα-stimulated Y1 adrenocortical cells. The treatments included the H2S donor NaHS, TNFα inhibitor R-7050, necroptosis inhibitor NSA and CBS inhibitor AOAA. Pathological assessment involved hematoxylin-eosin (H&E) staining and a Western blot analysis of necroptosis markers (the phosphorylation of MLKL (p-MLKL) and phosphorylation of receptor-interacting protein kinases 1 (p-RIPK1)). RESULTS Sepsis induced adrenal congestion, elevated TNFα levels, and activated necroptosis (increased p-MLKL/p-RIPK1) in wild-type mice. H2S treatment attenuated adrenal damage, reduced TNFα, and suppressed necroptosis. MLKL knockout reduced septic adrenal dysfunction, whereas CBS knockout exacerbated septic adrenal dysfunction. In vitro, TNFα induced Y1 cell necroptosis, which was reversed by H2S or NSA. AOAA exacerbated TNFα-induced necroptosis in Y1 cells. CONCLUSIONS H2S inhibits TNFα-mediated necroptosis, thereby preserving adrenal integrity in sepsis. Targeting the TNFα-necroptosis axis and enhancing endogenous H2S production may represent novel therapeutic strategies for sepsis-associated adrenal dysfunction.

Abstract
In the early stages of development, piglets exhibit immature intestinal morphology and function, rendering them susceptible to a range of internal and external stressors, such as viral and bacterial infection, and mycotoxin exposure, which causes intestinal damage. The intestinal damage is characterized by various types of cell death within intestinal epithelium. The traditional cell death types have been categorized as necrosis, apoptosis, and autophagy. However, recent research has identified several forms of novel regulated cell death (RCD) such as necroptosis, pyroptosis, and ferroptosis. A growing body of evidence has underscored the pivotal role of necroptosis, pyroptosis, and ferroptosis in intestinal damage in pigs. Moreover, intervention strategies have been shown to mitigate these 3 RCDs when pigs are exposed to excessive adverse factors. This review aims to elucidate the role of these emerging RCDs in intestinal damage and summarize current understanding of their regulation by nutrients and bioactive substances in pigs. Our goal was to provide future intervention strategies designed to alleviate intestinal damage in pigs.

Abstract
Crohn's disease (CD) and ulcerative colitis (UC), referred to as inflammatory bowel disease (IBD), pose considerable challenges in treatment because they are chronic conditions that easily relapse. The occurrence of IBD continues to rise in developing countries. Nonetheless, the existing therapies for IBD have limitations and fail to address the needs of the patients thoroughly. There is an increasing need for new, safe, and highly effective alternative medications for IBD patients. Traditional Chinese Medicine (TCM) is employed in drug development and disease management due to its wide-range of biological activities, minimal toxicity, and limited side effects. Extensive research has shown that certain TCM exhibits significant therapeutic benefits for IBD treatments. Honeysuckle (Lonicera japonica) was used in TCM research and clinical settings for the treatment of IBD. Bioactive metabolites in L. japonica, such as luteolin, quercetin, cyanidin, chlorogenic acid (CGA), caffeic acid (CA), and saponin, exhibit significant therapeutic benefits for managing IBD. The honeysuckle flower is a potential candidate in the treatment of IBD due to its anti-inflammatory, immune system-regulating, and antioxidant qualities. This paper reviews the metabolites of the honeysuckle flower as a candidate for the treatment of IBD. It discusses the fundamental mechanism of L. japonica and the potential of its bioactive metabolites in the prevention and treatment of IBD.

Suppression of cGAS/STING pathway-triggered necroptosis in the hippocampus relates H 2S to attenuate cognitive dysfunction of Parkinson's disease. Exp Neurol 2025; 385:115093. [PMID: 39637964 DOI: 10.1016/j.expneurol.2024.115093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2024] [Revised: 11/18/2024] [Accepted: 11/30/2024] [Indexed: 12/07/2024]
Abstract
BACKGROUND Cognitive dysfunction is the most severe non-motor symptom of Parkinson's disease (PD). Our previous study revealed that hydrogen sulfide (H2S) ameliorates cognitive dysfunction in PD, but the underlying mechanisms remain unclear. Hippocampal necroptosis plays a vital role in cognitive dysfunction, while the cGAS/STING pathway triggers necroptosis. To understand the mechanism underlying the inhibitory role of H2S in cognitive dysfunction of PD, we explored whether H2S reduces the enhancement of necroptosis and the activation of the cGAS/STING pathway in the hippocampus of the rotenone (ROT)-induced PD rat model. METHOD Adult Sprague-Dawley (SD) rats were pre-treated with NaHS (30 or 100 μmol/kg/d, i.p.) for 7 days and then co-treated with ROT (2 mg/kg/d, s.i.) for 35 days. The Y-maze and Morris water maze (MWM) tests were used to assess the cognitive function. Hematoxylin-eosin (H&E) staining was used to detect the hippocampal pathological morphology. Western blotting analysis was used to measure the expressions of proteins. Enzyme-linked immunosorbent assay was used to determine the levels of inflammatory factors. RESULT NaHS (a donor of H2S) mitigated cognitive dysfunction in ROT-exposed rats, according to the Y-maze and MWM tests. NaHS treatment also markedly down-regulated the expressions of necroptosis-related proteins (RIPK1, RIPK3, and MLKL) and decreased the levels of necroptosis-related inflammatory factors (IL-6 and IL-1β) in the hippocampus of ROT-exposed rats. Furthermore, NaHS treatment reduced the expressions of cGAS/STING pathway-related proteins (cGAS, STING, p-TBK1Ser172, p-IRF3Ser396, and p-P65Ser536) and decreased the contents of pro-inflammation factors (INF-β and TNF-α) in the hippocampus of ROT-exposed rats. CONCLUSION H2S attenuates the cGAS/STING pathway-triggered necroptosis in the hippocampus, which is related to H2S to attenuate cognitive dysfunction in PD.

Abstract
Aging is associated with the decline of tissue and cellular functions, which can promote the development of age-related diseases like cancer, cardiovascular disease, neurodegeneration, and disorders of the musculoskeletal and immune systems. Healthspan is the length of time an individual is in good health and free from chronic diseases and disabilities associated with aging. Two modifiable factors that can influence healthspan, promote healthy aging, and prevent the development of age-related diseases, are diet and microbiota in the gastrointestinal tract (gut microbiota). This review will discuss how dietary phytochemicals and gut microbiota can work in concert to promote a healthy gut and healthy aging. First, an overview is provided of how the gut microbiota influences healthy aging through its impact on gut barrier integrity, immune function, mitochondria function, and oxidative stress. Next, the mechanisms by which phytochemicals effect gut health, inflammation, and nurture a diverse and healthy microbial composition are discussed. Lastly, we discuss how the gut microbiota can directly influence health by producing bioactive metabolites from phytochemicals in food like urolithin A, equol, hesperetin, and sulforaphane. These and other phytochemical-derived microbial metabolites that may promote healthspan are discussed. Importantly, an individual's capacity to produce health-promoting microbial metabolites from cruciferous vegetables, berries, nuts, citrus, and soy products will be dependent on the specific bacteria present in the individual's gut.

Unraveling the Protective Effect of Hesperetin In Experimentally Induced Colitis: Inhibition of NF-κB and NLRP3 Inflammasome Activation. J Biochem Mol Toxicol 2025; 39:e70229. [PMID: 40096268 DOI: 10.1002/jbt.70229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2024] [Revised: 01/04/2025] [Accepted: 03/07/2025] [Indexed: 03/19/2025]
Abstract
This study aimed to investigate the protective effects of hesperetin (HES) against acetic acid (AA)-induced colitis (AAC) in rats through suppression of nuclear factor kappa B (NF-κB) and modulation of the NOD-like receptor pyrin-containing protein 3 (NLRP3) inflammasome. Forty-eight rats were allocated into four groups: control, AAC, HES-treated, and HES pre-treatment followed by AAC. Disease activity index (DAI), macroscopic and histological colonic changes were assessed. Moreover, inflammatory markers, and signaling pathways were evaluated through qRT-PCR, Western blot analysis, ELISA, and immunohistochemistry. HES pre-treatment significantly decreased the DAI by 61.31%, macroscopic colonic damage by 61.25% and the histological score by 41.86% compared to the AAC group. HES also reduced the expression of miR-155 by 73.79%, NLRP3 by 66.07%, Apoptosis-associated speck-like protein containing CARD (ASC) by 66.09%, cleaved caspase-1 by 63.86%, and the pyroptosis marker gasdermin-N (GSDMD-N) by 61.29%. Concurrently, HES attenuated the NF-κB pathway, reducing NF-κB-positive cells by 74.47% and p-inhibitory κB kinaseα (IκBα)/IκBα and p-Inhibitor of nuclear factor kappa-B kinase subunit alpha (IKKα/β)/IKKα/β levels by 43.77% and 38.68%, respectively. Inflammatory cytokines IL-1β and IL-18 were diminished by 73.41% and 71.88%, respectively. HES pre-treatment increased peroxisome proliferator-activated receptors-γ (PPAR-γ) expression by 259.97%, while reducing CD68+ macrophage infiltration by 72.72%. In conclusion, HES alleviated AAC in rats by targeting the NF-κB and NLRP3 inflammasome signaling pathways. This protective effect was mediated through the downregulation of miR-155 expression and the concurrent enhancement of PPAR-γ expression, resulting in reduced inflammation and pyroptosis. These findings highlight HES as a potential therapeutic protective agent for colitis.

Preclinical studies of natural flavonoids in inflammatory bowel disease based on macrophages: a systematic review with meta-analysis and network pharmacology. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2025; 398:2293-2318. [PMID: 39422746 DOI: 10.1007/s00210-024-03501-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Accepted: 09/30/2024] [Indexed: 10/19/2024]
Abstract
Flavonoid is a category of bioactive polyphenolic compounds that are extensively distributed in plants with specific pharmacological properties, such as anti-inflammatory and anti-oxidant. Importantly, natural flavonoids have shown the protected function on the dextran sulfate sodium (DSS)-induced colitis in animals and lipopolysaccharides (LPS)-induced inflammatory response in macrophages. The purpose of this systematic review is to explore the efficacy of natural flavonoids in animal models of IBD (inflammatory bowel disease) and potential mechanisms in macrophages by meta-analysis and network pharmacology in preclinical studies. Relevant foundation studies were searched from January 2010 to November 2023 in databases like PubMed, Elsevier ScienceDirect, and Web of Science. Then, OriginPro software was used to extract values from images, and the analysis was performed using Review Manager 5.3. The retrieved data was analyzed according to the fixed-effects model and random-effects model. Subsequently, heterogeneity was evaluated using the I2 statistics. Lastly, network pharmacology was applied to confirm mechanisms of natural flavonoids on IBD. According to the results of meta-analysis, we found the natural flavonoids exhibited powerful therapeutic effects against IBD, which not only reversed colonic shortness (WMD = 1.33, 95% CI (1.07, 1.59), P < 0.00001), but also reduced histological score (SMD = - 2.66, 95% CI (- 3.77, - 1.95), P < 0.00001) between natural flavonoid treatment groups compared with the experimental IBD model. Furthermore, treatment with natural flavonoids decreased the levels of tumor necrosis factor-α (TNF-α) in macrophages. Mechanistically, our summarized data substantiate that natural flavonoids alleviate LPS-induced M1 macrophage polarization, anti-oxidant, anti-inflammatory, maintain intestinal barrier, and inhibit the activation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome in macrophages. Moreover, the results of network pharmacology also support this. This systematic review demonstrated the efficiency of natural flavonoids in treating IBD in preclinical research by meta-analysis and network pharmacology, which offered supporting evidence for clinical trial implementation. However, some limitations remain present, such as technique quality shortage, missed reports on account of negative results, failure to count sample size, and the risk of bias.

Abstract
Mixed lineage kinase domain-like protein (MLKL) is a pseudokinase featured by a protein kinase-like domain without catalytic activity. MLKL was originally discovered to be phosphorylated by receptor-interacting protein kinase 1/3, typically increase plasma membrane permeabilization, and disrupt the membrane integrity, ultimately executing necroptosis. Recent evidence uncovers the association of MLKL with diverse cellular organelles, including the mitochondrion, lysosome, endosome, endoplasmic reticulum, and nucleus. Thus, this review mainly focuses on the regulatory functions, mechanisms, and targets of MLKL in organelles rather than necroptosis and summarize the medical significance in multiple diseases. On this basis, we conclude and analyze the current progress and prospect for the development of MLKL-related drugs, from natural products, small-molecule chemical compounds, to proteolysis-targeting chimera. This review is aimed to propel the development of MLKL as a valid drug target and the discovery of novel MLKL-related drugs, and promote their further applications.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory disease of the colon that is associated with dysbiosis in the gut microbiota. Eisenia bicyclis, a marine alga, is known for its anti-inflammatory, antioxidant, and gut microbiota-modulating properties. This study explored the mechanisms by which a 70% ethanol extract of E. bicyclis may alleviate UC, through both in vitro and in vivo experiments. LC-MS/MS analysis revealed eckol, 7-phloroeckol, dieckol, phlorofucofuroeckol A, and fucofuroeckol as key phenolic compounds present in the extract. The administration of E. bicyclis significantly improved symptoms in a dextran sulfate sodium (DSS)-induced colitis mouse model by reducing intestinal shortening, splenomegaly, and histological scores. Both cell and animal studies demonstrated that E. bicyclis suppressed the release of inflammatory cytokines, downregulated the mRNA expression of genes related to the mTOR pathway, and reduced the p-mTOR/mTOR ratio. Microbiota analysis revealed that, while the Firmicutes/Bacteroidetes ratio was elevated in UC mice, E. bicyclis administration normalized this imbalance, with a notable increase in the abundance of beneficial probiotics such as Bifidobacterium bifidum. In conclusion, a phenolic-rich extract of E. bicyclis demonstrates significant potential as a dietary supplement to prevent and mitigate UC by modulating both the mTOR signaling pathway and gut microbiota composition.

Abstract
Flavonoids such as silibinin, hesperetin, and phloretin exhibit well-documented biological activities, including anti-inflammatory, cytoprotective, anticarcinogenic, and antioxidant effects. However, their clinical application remains limited due to challenges such as poor aqueous solubility, low bioavailability, and restricted intestinal absorption, which can significantly reduce their pharmacological efficacy. This review analyzed patents related to innovative pharmaceutical technologies for flavonoids. The analysis used databases from the World Intellectual Property Organization and the European Patent Office. Following a comprehensive screening process, 38 patents were selected for detailed examination. These patents highlighted numerous studies on novel formulations, characterizations, and proprietary conditions. This review highlights technologies, such as nanocapsules, nanoemulsions, solid dispersions, phospholipid carriers, inclusion complexes, microemulsions, and other advanced systems, which enhance bioactive molecules' water solubility and stability. Consequently, these technologies improve permeability and absorption through the intended administration route, demonstrating the potential of flavonoids as promising candidates for various treatments, particularly when integrated into pharmaceutical technologies.

Abstract
BACKGROUND The clinical efficacies of Ulcerative colitis (UC) are far from satisfactory. Fucoxanthin (FUC) is a marine carotenoid that is abundant in seaweed and microalgae. It has been reported that FUC can possess anti-inflammatory and antioxidant. However, its mechanism and role in UC is yet to be clarified. This study aimed to investigate the protective effect and potential mechanism of FUC extracted from the diatom Phaeodactylum tricornutm on dextran sodium sulfate (DSS) -induced colitis. METHODS Animal UC model was induced by DSS and cellular model was established by TNF-α. Immunohistochemical staining, Western blot, RT-qPCR, and immunofluorescence were used to assess the inflammatory responses and epithelial barrier in vivo and in vitro models. RESULTS The results showed that FUC attenuates DSS-induced colitis by ameliorating the epithelial mucosal barrier. Moreover, FUC possessed antioxidant and anti-inflammatory effects on NCM460 cells. JAK/STAT activator RO8191 could reverse these changes. CONCLUSION FUC exerted anti-inflammatory and antioxidant effects via the JAK2/STAT3 signaling pathway, and served as a potential therapeutic agent for the treatment of UC.

Abstract
Intestinal mucus, a viscoelastic medium with mucin2 (MUC2) as its main component, covers the surface of intestinal epithelial cells and protects the intestine from invasion, forming the first barrier of the intestinal tract. Unlike the small intestine, where the mucus layer is a single layer, the colonic mucus layer can be divided into a sterile inner layer and an outer layer with bacterial colonization. Many of the substances in the mucus layer have beneficial effects on the intestinal epithelium, but the mucus layer is often affected by a variety of factors, mainly microbiological, dietary, and immunological. Inflammatory bowel disease (IBD) is a disease of increasing morbidity worldwide, with a complex etiology and a high relapse rate. In recent years, the mucus barrier in IBD has received increasing attention and is considered a key factor in the pathogenesis of IBD. Loss of goblet cells (GCs) and changes in the composition and properties of the mucus layer material are commonly found in the colon of IBD patients. Damage to the mucus layer may make it easier for microorganisms to access the intestinal epithelium and cause inflammation. There are currently a number of herbs and other therapies that can be used to treat IBD and repair the damaged mucus barrier. This review highlights the important role of the mucus layer in IBD and the therapies that target the mucus layer in IBD.

Dachengqi decoction ameliorated liver injury in liver fibrosis mice by maintaining gut vascular barrier integrity. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2025; 136:156272. [PMID: 39577253 DOI: 10.1016/j.phymed.2024.156272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 11/12/2024] [Accepted: 11/16/2024] [Indexed: 11/24/2024]
Abstract
BACKGROUND Severe liver fibrosis may be accompanied by intestinal barrier damage, such as bacterial peritonitis, suggesting that the role of the gut-liver axis is nonnegligible. Dachengqi decoction (DCQD) was reported to improve bowel movements, but whether DCQD was effective for intestinal damage caused by liver fibrosis remained unclear. PURPOSE To investigate the role of DCQD in liver fibrosis-related gut vascular barrier (GVB) damage in mice. STUDY DESIGN DCQD was verified to reduce the imbalance of the intestinal vascular barrier and restore intestinal homeostasis to prove that DCQD acts through the gut-liver axis. METHODS Three graded doses of DCQD were gavaged into the CCL4-induced mice for 12 weeks to evaluate the resistance to liver and intestinal damage. Immunoblotting and primary flow cytometry were used to assess organ damage; PV-1 to indicate gut vascular barrier damage; serum endotoxin, fecal SCFAs, and liver microbiota translocation to examine the gut-liver axis's crosstalk. Network pharmacology and RNA sequencing were used to analyze and verify the signaling pathway of DCQD. RESULTS DCQD significantly ameliorated fibrosis and inflammatory response in the CCL4-induced mice, alleviated gut leakage, downregulated PV-1, relieved liver enterobacterial translocation, restored intestinal homeostasis, and reduced infiltration of myeloid cells in the lamina propria. Network pharmacology and RNA sequencing results indicated that DCQD exerted anti-fibrotic and anti-inflammatory effects in the liver through inhibition of the ESR1/NF-κB/TNFα pathway and maintained GVB homeostasis through the FUT2/Wnt/β-Catenin pathway. CONCLUSIONS DCQD broke the closed-loop damage of the gut-liver axis to improve GVB injury in mice with liver fibrosis.

Abstract
Hesperetin is a flavonoid compound naturally occurring in the peel of Citrus fruits from the Rutaceae family. Previous studies have demonstrated that hesperetin exhibits various pharmacological effects, such as anti-inflammatory, anti-tumor, antioxidative, anti-aging, and neuroprotective properties. In recent years, with the increasing prevalence of diseases and the rising awareness of traditional Chinese medicine, hesperetin has garnered growing attention for its wide-ranging pharmacological effects. To substantiate its health benefits and elucidate potential mechanisms, knowledge of pharmacokinetics is crucial. However, the limited solubility of hesperetin restricts its bioavailability, thereby diminishing its efficacy as a beneficial health agent. To enhance the bioavailability of hesperetin, various novel formulations have been developed, including nanoparticles, liposomes, and cyclodextrin inclusion complexes. This article reviews recent advances in the pharmacokinetics of hesperetin and methods to improve its bioavailability, as well as its pharmacological effects and mechanisms, aiming to provide a theoretical basis for clinical applications.

Abstract
BACKGROUND AND AIM Selenium, an essential micronutrient for human and has been reported to have a protective effect in ulcerative colitis (UC). However, the role of selenium in UC is unclear. Our aim was to investigate the mechanism of action of selenium in UC. METHODS Serum selenium levels were measured in UC patients and healthy controls. In addition, the effect of sodium selenite supplementation on experimental colitis in mice treated with dextran sulfate sodium (DSS) was investigated. The effect of sodium selenite on IECs ferroptosis was evaluated by observing the cell mortality, intracellular ferrous content, lipid reactive oxygen species and mitochondrial membrane damage in DSS-treated Caco2 cells. In addition, glutathione peroxidase 4 (Gpx4) and nuclear factor erythroid 2-like 2 (Nrf2) were detected in Caco2 cells and mouse intestines to explore their mechanisms. RESULTS The serum selenium content of UC patients was lower than that of healthy subjects. In addition, serum selenium levels were negatively correlated with disease activity. The in vivo results showed that selenium treatment could improve colitis induced by DSS and inhibit IECs ferroptosis. The in vitro results further showed that selenium inhibited the ferroptosis of Caco-2 cells induced by DSS. Nrf2/Gpx4 was up-regulated after selenium supplementation in vivo and in vitro. CONCLUSIONS Serum selenium level is associated with IECs ferroptosis in UC patients. Selenium can relieve DSS-induced colitis and inhibit IECs ferroptosis by up-regulating the expression of Nrf2/Gpx4.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 333:118503. [PMID: 38942157 DOI: 10.1016/j.jep.2024.118503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Revised: 06/11/2024] [Accepted: 06/25/2024] [Indexed: 06/30/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Citri Reticulatae Pericarpium (CRP), known as Chen Pi in China, is the most commonly used medicine for regulating qi. As a traditional medicine, CRP has been extensively used in the clinical treatment of nausea, vomiting, cough and phlegm for thousands of years. It is mainly distributed in Guangdong, Sichuan, Fujian and Zhejiang in China. Due to its high frequency of use, many scholars have conducted a lot of research on it and the related chemical constituents it contains. In this review, the research progress on phytochemistry, pharmacology, pharmacokinetics and toxicology of CRP are summarized. AIM OF THE REVIEW The review aims to sort out the methods of extraction and purification, pharmacological activities and mechanisms of action, pharmacokinetics and toxicology of the chemical constituents in CRP, in order to elaborate the future research directions and challenges for the study of CRP and related chemical constituents. MATERIALS AND METHODS Valid and comprehensive relevant information was collected from China National Knowledge Infrastructure, Web of Science, PubMed and so on. RESULTS CRP contains a variety of compounds, of which terpenes, flavonoids and alkaloids are the main components, and they are also the primary bioactive components that play a pharmacological role. Flavonoids and terpenes are extracted and purified by aqueous and alcoholic extraction methods, assisted by ultrasonic and microwave extraction, in order to achieve higher yields with less resources. Pharmacological studies have shown that CRP possesses a variety of highly active chemical components and a wide range of pharmacological activities, including anti-tumor, anti-inflammatory, immunomodulatory, hepatoprotective, therapeutic for cardiovascular-related disorders, antioxidant, antibacterial, and neuroprotective effects. CONCLUSIONS There is a diversity in the chemical compositions of CRP, which have multiple biological activities and promising applications. However, the pharmacological activities of CRP are mainly dependent on the action of its chemical components, but the relationship between the structure of chemical components and the biological effects has not been thoroughly investigated, and therefore, the structure-activity relationship is an issue that needs to be elucidated urgently. In addition, the pharmacokinetic studies of the relevant components can be further deepened and the correlation studies between pharmacological effects and syndromes of TCM can be expanded to ensure the effectiveness and rationality of CRP for human use.

Targeted no-releasing L-arginine-induced hesperetin self-assembled nanoparticles for ulcerative colitis intervention. Acta Biomater 2024:S1742-7061(24)00628-7. [PMID: 39461688 DOI: 10.1016/j.actbio.2024.10.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2024] [Revised: 10/07/2024] [Accepted: 10/23/2024] [Indexed: 10/29/2024]
Abstract
Overproduction of reactive oxygen species (ROS) plays a crucial role in initiating and advancing ulcerative colitis (UC), and the persistent cycle between ROS and inflammation accelerates disease development. Therefore, developing strategies that can effectively scavenge ROS and provide targeted intervention are crucial for the management of UC. In this study, we synthesized natural carrier-free nanoparticles (HST-Arg NPs) using the Mannich reaction and π-π stacking for the intervention of UC. HST-Arg NPs are an oral formulation that exhibit good antioxidant capabilities and gastrointestinal stability. Benefiting from the negatively charged characteristics, HST-Arg NPs can specifically accumulate in positively charged inflamed regions of the colon. Furthermore, in the oxidative microenvironment of colonic inflammation, HST-Arg NPs respond to ROS by releasing nitric oxide (NO). In mice model of UC induced by dextran sulfate sodium (DSS), HST-Arg NPs significantly mitigated colonic injury by modulating oxidative stress, lowering pro-inflammatory cytokines, and repairing intestinal barrier integrity. In summary, this convenient and targeted oral nanoparticle can effectively scavenge ROS at the site of inflammation and achieve gas intervention, offering robust theoretical support for the development of subsequent oral formulations in related inflammatory interventions. STATEMENT OF SIGNIFICANCE: Nanotechnology has been extensively explored in the biomedical field, but the application of natural carrier-free nanotechnology in this area remains relatively rare. In this study, we developed a natural nanoparticle system based on hesperetin (HST), L-arginine (L-Arg), and vanillin (VA) to scavenge ROS and alleviate inflammation. In the context of ulcerative colitis (UC), the synthesized nanoparticles exhibited excellent intervention effects, effectively protecting the colon from damage. Consequently, these nanoparticles provide a promising and precise nutritional intervention strategy by addressing both oxidative stress and inflammatory pathways simultaneously, demonstrating significant potential for application.

Abstract
Introduction Obesity, which is associated with gut microbiota dysbiosis, low-grade chronic inflammation and intestinal barrier dysfunction, can cause a variety of chronic metabolic diseases. Phytochemical flavonoids have a variety of biological activities, among which there may be safe and effective anti-obesity solutions. Methods We tested a plant-derived flavonoid hesperidin and fecal microbiota transplantation (FMT) to alleviate diet-induced obesity. High-fat diet (HFD)-fed mice were treated with hesperidin (100 and 200 mg/kg BW) and FMT. Results Results indicated that hesperidin had the effects of reducing obesity as indicated by reduction of body weight, fat accumulation and blood lipids, reducing inflammation as indicated by reduction of pro-inflammation factors including TNFα, IL-6, IL-1βand iNOS, and improving gut integrity as indicated by increasing colon length, reducing plasma gut permeability indicators iFABP and LBP, increased mRNA expression of mucus protein Muc2, tight junction p Claudin 2, Occludin and ZO-1 in the HFD-fed mice. The anti-obesity effects of hesperidin treatment have a dose-dependent manner. In addition, 16S rRNA-based gut microbiota analysis revealed that hesperidin selectively promoted the growth of Lactobacillus salivarius, Staphylococcus sciuri and Desulfovibrio C21_c20 while inhibiting Bifidobacterium pseudolongum, Mucispirillum schaedleri, Helicobacter ganmani and Helicobacter hepaticus in the HFD-fed mice. Horizontal feces transfer from the normal diet (ND)-fed mice to the HFD-fed mice conferred anti-obesity effects and transmitted some of the HFD-modulated microbes. Conclusion We concluded that hesperidin and FMT both affect the reduction of body weight and improve HFD-related disorders in the HFD-fed mice possibly through modulating the composition of the gut microbiota.

Abstract
Autoimmunity is a normal physiological state that requires immunological homeostasis and surveillance, whereas necroptosis is a type of inflammatory cell death. When necroptosis occurs, various immune system cells must perform their appropriate duties to preserve immunological homeostasis, whether the consequence is expanding or limiting the inflammatory response and the pathological condition is cleared or progresses to the autoimmune disease stage. This article discusses necroptosis based on RIP homotypic interaction motif (RHIM) interaction under various physiological and pathological situations, with the RIPK1-RIPK3-MLKL necrosome serving as the regulatory core. In addition, the cell biology of necroptosis involved in autoimmunity and its application in autoimmune diseases were also reviewed.

Abstract
Inflammatory bowel disease (IBD), which encompasses Crohn's disease (CD) and ulcerative colitis (UC), is a complicated illness whose exact cause is yet unknown. Necroptosis is associated with IBD pathogenesis, leading to intestinal barrier abnormalities and uncontrolled inflammation. Molecules involved in necroptosis, however, exhibit different expression levels in IBD and its associated colorectal cancer. Multiple studies have shown that inhibiting these molecules alleviates necroptosis-induced IBD. Moreover, due to the severe scarcity of clinical medications for treating IBD caused by necroptosis, we review the various functions of crucial necroptosis molecules in IBD, the stimuli regulating necroptosis, and the current emerging therapeutic strategies for treating IBD-associated necroptosis. Eventually, understanding the pathogenesis of necroptosis in IBD will enable the development of additional therapeutic approaches for the illness.

Abstract
NIBV is an acute and highly contagious virus that has a major impact on the poultry industry. Wogonin, as a flavonoid drug, has antiviral effects, but there have been no reports indicating its role in renal injury caused by NIBV infection. The aim of this study is to investigate the antiviral effect of wogonin against NIBV. Renal tubular epithelial cells were isolated and cultured, and divided into four groups: Con, Con+Wog, NIBV and NIBV+Wog. We found that wogonin significantly inhibited the copy number of NIBV and significantly alleviated NIBV-induced cell apoptosis and necrosis. Moreover, wogonin inhibited the reduction in mitochondrial membrane potential and the aberrant opening of mPTP caused by NIBV. In conclusion, wogonin can protect renal tubular epithelial cells from damage by inhibiting the replication of NIBV and preventing mitochondrial apoptosis and necroptosis induced by NIBV.

Abstract
Cembranolides are characteristic metabolites in marine soft corals, with complex structures and widespread biological activities. However, seldom has an intensive pharmacological study been done for these intriguing marine natural products. In this work, systematic chemical investigation was performed on Sinularia pedunculata by HSQC-based small molecule accurate recognition technology (SMART), resulting in the isolation and identification of 31 cembrane-type diterpenoids, including six new ones. In the bioassay, several compounds showed significant anti-inflammatory activities on the inhibition of NO production. The structure-activity relationship (SAR) was comprehensively analyzed, and two most bioactive and less toxic compounds 8 and 9 could inhibit inflammation through suppressing NF-κB and MAPK signaling pathways, and reduce the secretion of inflammatory cytokines. In a mouse model of dextran sodium sulfate (DSS)-induced acute colitis, 8 and 9 exhibited good anti-inflammatory effects and the ability to repair the colon epithelium, giving insight into the application of cembranolides as potential ulcerative colitis (UC) agents.

Gao Y, Yang L, Yao Q, Wang J, Zheng N. Butyrate improves recovery from experimental necrotizing enterocolitis by metabolite hesperetin through potential inhibition the PI3K-Akt pathway. Biomed Pharmacother 2024; 176:116876. [PMID: 38850657 DOI: 10.1016/j.biopha.2024.116876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 06/03/2024] [Accepted: 06/03/2024] [Indexed: 06/10/2024] Open
Abstract
Necrotizing enterocolitis (NEC) is one of the most common and serious intestinal illnesses in newborns and seriously affects their long-term prognosis and survival. Butyrate is a short-chain fatty acid that can relieve intestinal inflammation, but its mechanism of action is unclear. Results from an in vivo neonatal rat model has shown that butyrate caused an improved recovery from NEC. These protective effects were associated with the metabolite of hesperetin, as determined by metabolomics and molecular biological analysis. Furthermore, transcriptomics combined with inhibitor assays were used to investigate the mechanism of action of hesperetin in an in vitro NEC model (IEC-6 cells exposed to LPS) to further investigate the mechanism by which butyrate attenuates NEC. The transcriptomics analysis showed that the PI3K-Akt signaling pathway was involved in the anti-NEC effect of hesperitin. Subsequently, the results using an inhibitor of PI3K (LY294002) indicated that the suppression could be explained by the hesperetin-induced expression of tight junction (TJ) proteins by potentially blocking the PI3K-Akt signaling pathway. In summary, the present study demonstrated that butyrate could improve recovery from NEC with a hesperetin metabolite, causing potential inhibition of the phosphorylation of the PI3K-Akt signaling pathway, resulting in the increased expression of TJ proteins. These findings reveal a potential new therapeutic pathway for the treatment of NEC.

Ziziphus jujuba Miller Ethanol Extract Restores Disrupted Intestinal Barrier Function via Tight Junction Recovery and Reduces Inflammation. Antioxidants (Basel) 2024; 13:575. [PMID: 38790680 PMCID: PMC11118233 DOI: 10.3390/antiox13050575] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 05/03/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory condition caused by the disruption of the intestinal barrier. The intestinal barrier is maintained by tight junctions (TJs), which sustain intestinal homeostasis and prevent pathogens from entering the microbiome and mucosal tissues. Ziziphus jujuba Miller (Z. jujuba) is a natural substance that has been used in traditional medicine as a therapy for a variety of diseases. However, in IBD, the efficacy of Z. jujuba is unknown. Therefore, we evaluated ZJB in Caco2 cells and a dextran sodium sulfate (DSS)-induced mouse model to demonstrate its efficacy in IBD. Z. jujuba extracts were prepared using 70% ethanol and were named ZJB. ZJB was found to be non-cytotoxic and to have excellent antioxidant effects. We confirmed its anti-inflammatory properties via the down-regulation of inflammatory factors, including inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). To evaluate the effects of ZJB on intestinal barrier function and TJ improvement, the trans-epithelial electrical resistance (TEER) and fluorescein isothiocyanate-dextran 4 kDa (FITC-Dextran 4) permeability were assessed. The TEER value increased by 61.389% and permeability decreased by 27.348% in the 200 μg/mL ZJB group compared with the 50 ng/mL IL-6 group after 24 h. Additionally, ZJB alleviated body weight loss, reduced the disease activity index (DAI) score, and induced colon shortening in 5% DSS-induced mice; inflammatory cytokines, tumor necrosis factor (TNF)-α, and interleukin (IL)-6 were down-regulated in the serum. TJ proteins, such as Zonula occludens (ZO)-1 and occludin, were up-regulated by ZJB in an impaired Caco2 mouse model. Additionally, according to the liquid chromatography results, in tandem with mass spectrometry (LC-MS/MS) analysis, seven active ingredients were detected in ZJB. In conclusion, ZJB down-regulated inflammatory factors, protected intestinal barrier function, and increased TJ proteins. It is thus a safe, natural substance with the potential to be used as a therapeutic agent in IBD treatment.

Life Sci 2024; 342:122533. [PMID: 38428570 DOI: 10.1016/j.lfs.2024.122533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 02/20/2024] [Accepted: 02/21/2024] [Indexed: 03/03/2024]
Abstract
The World Health Organization recommends breastfeeding for 6 months, but mastitis, a common disease during lactation, presents a major obstacle to fulfilling this recommendation. Maternal nutrient intake during lactation has been shown to be related to mastitis. Therefore, this study aimed to explore the effect of hesperetin, a phytonutrient, on mastitis. The oral administration of hesperetin to lipopolysaccharide (LPS)-induced mastitis mice alleviated their pathological damage, reduced the secretion of pro-inflammatory cytokines, and maintained the integrity of their blood-milk barrier. Moreover, our results showed that oral administration of hesperetin regulates the composition of the intestinal flora of mice. Fecal microbial transplantation (FMT) from the mice of hesperetin group alleviated LPS-induced mastitis in recipient mice. In additional, hesperetin attenuated the inflammatory response and increased the expression of tight junction proteins (TJs) in LPS-stimulated mouse mammary epithelial cells (mMECs). Through network pharmacological analysis and further research, we demonstrated hesperetin inhibits the expression of TLR4 and the activation of NF-κB signaling. In conclusion, hesperetin protects the blood-milk barrier and improve mastitis by regulating intestinal flora and inhibiting the activation of TLR4/NF-κB signaling axis. This study provides a theoretical basis for lactating females to consume hesperetin as a supplement to prevent mastitis and maintain mammary health.

Abstract
The plant Acalypha indica L. is a well-known traditional plant belonging to the family Euphorbiaceae. Traditional practices of the plant claim to treat asthma, pneumonia, wound healing, rheumatoid arthritis, bronchitis, and skin disorders. The major phytochemicals reported are cyanogenic glucosides, tannins, coumarins, flavonoid glycosides, fatty acids, and volatile oils. To summarize the anti-inflammatory potential of Acalypha indica extract and its phytochemicals through preclinical studies. The search terms include anti-inflammatory, Acalypha indica, and Acalypha indica extract independently or in combination with pro-inflammatory markers using various databases, including Scopus, Web of Science, PubMed, ProQuest, and Google Scholar. The results of preclinical studies confirm that Acalypha indica exhibits strong anti-inflammatory activity. Most of the experimental studies that have been conducted on plant extract are protein denaturation, human red blood cell membrane stabilization assay, and carrageenan-induced inflammation models. However, the molecular mechanism in these studies is still unclear to demonstrate its anti-inflammatory effects. Acalypha indica possesses anti-inflammatory effects that may be due to the presence of phenolic compounds especially flavonoids present in the Acalypha indica. Thus, further research is needed, to understand mechanistic insights of the plant phytochemicals to represent anti-inflammatory properties.

Abstract
Ulcerative colitis (UC) is a nonspecific inflammatory bowel disease characterized by abdominal pain, bloody diarrhea, weight loss, and colon shortening. However, UC is difficult to cure due to its high drug resistance rate and easy recurrence. Moreover, long-term inflammation and increased disease severity can lead to the development of colon cancer in some patients. Programmed cell death (PCD) is a gene-regulated cell death process that includes apoptosis, autophagy, necroptosis, ferroptosis, and pyroptosis. PCD plays a crucial role in maintaining body homeostasis and the development of organs and tissues. Abnormal PCD signaling is observed in the pathological process of UC, such as activating the apoptosis signaling pathway to promote the progression of UC. Targeting PCD may be a therapeutic strategy, and natural compounds have shown great potential in modulating key targets of PCD to treat UC. For instance, baicalin can regulate cell apoptosis to alleviate inflammatory infiltration and pathological damage. This review focuses on the specific expression of PCD and its interaction with multiple signaling pathways, such as NF-κB, Nrf2, MAPK, JAK/STAT, PI3K/AKT, NLRP3, GPX4, Bcl-2, etc., to elucidate the role of natural compounds in targeting PCD for the treatment of UC. This review used (ulcerative colitis) (programmed cell death) and (natural products) as keywords to search the related studies in PubMed and the Web of Science, and CNKI database of the past 10 years. This work retrieved 72 studies (65 from the past 5 years and 7 from the past 10 years), which aims to provide new treatment strategies for UC patients and serves as a foundation for the development of new drugs.

Abstract
Microsporidia are intracellular fungus-like pathogens and the infection symptoms include recurrent diarrhea and systematic inflammations. The major infection route of microsporidia is the digestive tract. Since microsporidia are hard to fully eliminate, the interactions and persistence of the pathogen within epithelium may modulate host susceptibility to digestive disorders. In this study, both in vitro and in vivo infection models were applied. The alterations of epithelial barrier integrity, permeability, and tight junction proteins after microsporidia infection were assessed on MDCK/Caco-2 monolayers. The fecal intestinal microbiota and tissue alterations after microsporidia infection were assessed on C57BL/6 mice. Moreover, the susceptibility to develop dextran sulfate sodium (DSS)-induced inflammatory bowel diseases (IBDs) was also analyzed by the murine infection model. The results demonstrated that microsporidia infection increased epithelium permeability, weakened wound healing capability, and destructed tight junction protein zonula occludens-1. Microsporidia infection also dysregulates intestinal microbiota. These impairing effects of microsporidia increased host vulnerability to develop enteritis as shown by the murine model of DSS-induced IBD. Our study is the first to elucidate molecular mechanisms of the damaging effects of microsporidia on host epithelium and pointed out the cryptic threats of latent microsporidia infection to public health as reflected by the increased chances of developing more severe diseases.IMPORTANCEMicrosporidia are widely present in nature and usually cause latent and persistent infections in hosts. Given the fact that the digestive tract is the major infection route, it is of great importance to explore the consequences of microsporidia infection on the intestinal epithelial barrier and the risks to the host. In this study, we demonstrated the destructing effects of microsporidium infection on epithelial barriers manifested as increased epithelial permeability, weakened wound healing ability, and disrupted tight junctions. Moreover, microsporidia made the host more susceptible to dextran sulfate sodium-induced inflammatory bowel disease. These findings provide new evidence for us to better understand and develop novel strategies for microsporidia prevention and disease control.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The traditional Chinese herb, Sargentodoxa cuneata, is primarily utilized as a crucial herb for managing ulcerative colitis (UC), also known as "Da Xue Teng (DXT)" or "Hong Teng" in Chinese. Nevertheless, the chemical composition, prototype, and metabolite constituents of DXT and its pharmacological mechanism of treatment for UC remain unclear. AIM OF THE STUDY Necroptosis, a caspase-independent form of programmed cell death, plays a crucial role in the inflammatory pathogenesis of UC. The occurrence of necroptosis in intestinal epithelial cells triggers a robust inflammatory response and disrupts the integrity of both the mucinous barrier and tight junction construction. The objective of our study was to determine the chemical composition of DXT, identify its absorbed active ingredients and metabolites in rat serum, and investigate whether DXT possesses epithelial barrier protective effects by inhibiting necroptosis. MATERIALS AND METHODS First, the UPLC-Q-TOF/MS was applied to identify the chemical composition of DXT, as well as the absorption components and metabolites of DXT in rat serum. Second, the network pharmacology analysis was further investigated to elucidate the potential targets for treating UC. Finally, the mechanism of action was validated by necroptosis-based experiment in vitro and an in vivo model of colitis. RESULTS A comprehensive analysis revealed the presence of 31 phytochemicals derived from DXT herb, as well as a total of 39 components in rat serum. Network pharmacology analysis indicated that TNF, EGFR, HSP90, etc. are the potential targets. Experimental in vitro and in vivo verified that the DXT could improve disease activity index, body weight, colon length and intestinal barrier permeability in mice with colitis by inhibiting necroptosis of intestinal epithelial cells. CONCLUSIONS In this study, the phytochemicals derived from DXT herb and absorption active ingredients and metabolites of DXT in rat serum were analyzed. The biological mechanism of treatment for UC can be elucidated by combining network pharmacology investigation with experimental in vitro and in vivo studies. The findings offered a theoretical basis for comprehending the bioactive substances and the pharmacological process of DXT.

Abstract
Many bioactive plant compounds, known as phytochemicals, have the potential to improve health. Unfortunately, the bioavailability and bioactivity of phytochemicals such as polyphenolic flavonoids are reduced due to conjugation with sugar moieties. Here, we combine acid hydrolysis and tailored fermentation by lactic acid bacteria (Lactiplantibacillus plantarum) to convert the biologically less active flavonoid glycosides hesperidin and naringin into the more active aglycones hesperetin and naringenin. Using a comprehensive approach, we identify the most effective hydrolysis and fermentation conditions to increase the concentration of the aglycones in citrus extracts. The higher cellular transport and bioactivity of the biotransformed citrus extract are also demonstrated in vitro and in vivo. Superior antioxidant, anti-inflammatory and cell migration activities in vitro, as well as intestinal barrier protecting and antioxidant activities in Drosophila melanogaster are identified. In conclusion, the presented biotransformation approach improves the bioactivity of flavonoids, clearly traced back to the increase in aglycone content.

Abstract
As the dominant herbal drink consumed worldwide, black tea exhibits various health promoting benefits including amelioration of inflammatory bowel diseases. Despite extensive studies on the tea's components, little is known about the bioactivities of nanoparticles (NPs) which were incidentally assembled in the tea infusion and represent the major components. This study investigated the alleviative effects of black tea infusion, the isolated black tea NPs, and a mixture of caffeine, epigallocatechin-3-gallate, gallic acid and epicatechin gallate on dextran sodium sulfate (DSS)-induced ulcerative colitis. The results showed that both the black tea infusion and the NPs significantly alleviated colitis, suppressed the mRNA levels of pro-inflammatory cytokines TNF-α, IL-6, and IL-1β, and suppressed the DSS-induced loss of cell-cell junction proteins (e.g., E-cadherin, ZO-1, and claudin-1) and increase of p-STAT3. The mixture of four tea components, which is the analogue of bioactive payloads carried by the NPs, was much less effective than the tea infusion and NPs. It shows that the NPs elevate the efficiency of polyphenols and caffeine in black tea in restoring the intercellular connection in the intestine, inhibiting mucosal inflammation, and alleviating ulcerative colitis. This work may inspire the development of tea-based therapeutics for treating inflammatory bowel diseases and have wide influences on value-added processing, quality evaluation, functionalization, and innovation of tea and other plant-based beverages.

Abstract
Ulcerative colitis (UC) is a chronic gastroenteric inflammatory disease that may cause life-threatening complications. Currently available therapeutic drugs are not as effective as expected, necessitating the development of new targets and drugs. The etiology and pathogenetic mechanisms of UC are largely unclear; thus, the treatment effects are limited. The aqueous extract of Acalypha australis L. (AAL) has shown good therapeutic efficacy in treating UC. AAL is used in traditional Chinese medicine owing to its hemostasis, detoxification, and heat clearance effects. Although astragalus has such broad-spectrum biological activities closely related to inflammation, its therapeutic efficacy for UC treatment has not been reported, the underlying mechanism remains unknown. We studied the therapeutic effect of AAL on UC in mice and explored its potential mechanism. Mice were treated with AAL aqueous extract for 7 days (20 mg/kg), after which the colon tissue was assessed for damage (colon mucosal damage index [CMDI]), apoptosis (immunohistochemistry), and release of cytokines (enzyme-linked immunosorbent assay). The concentration of AAL aqueous extract at 20 mg/kg significantly improved the CMDI score and colon injury of UC model. It also reduced the serum levels of IL-2, IL-8, IL-17A, IL-22, IFN-γ, and TNF-α, and decreased apoptosis in the colon. AAL water extract also significantly reduced the expression level of NF-κB pathway-related proteins. In conclusion, AAL can protect against UC mainly by inhibiting the expression level of NF-κB pathway-related proteins and reducing the release of inflammatory factors.

Abstract
Alveolar epithelial barrier is a potential therapeutic target for acute respiratory distress syndrome (ARDS). However, an effective intervention against alveolar epithelial barrier has not been developed. Here, based on single-cell RNA and mRNA sequencing results, death receptor 3 (DR3) and its only known ligand tumor necrosis factor ligand-associated molecule 1A (TL1A) were significantly reduced in epithelium from an ARDS mice and cell models. The apparent reduction in the TL1A/DR3 axis in lungs from septic-ARDS patients was correlated with the severity of the disease. The examination of knockout (KO) and alveolar epithelium conditional KO (CKO) mice showed that TL1A deficiency exacerbated alveolar inflammation and permeability in lipopolysaccharide (LPS)-induced ARDS. Mechanistically, TL1A deficiency decreased glycocalyx syndecan-1 and tight junction-associated zonula occludens 3 by increasing cathepsin E level for strengthening cell-to-cell permeability. Additionally, DR3 deletion aggravated barrier dysfunction and pulmonary edema in LPS-induced ARDS through the above mechanisms based on the analyses of DR3 CKO mice and DR3 overexpression cells. Therefore, the TL1A/DR3 axis has a potential value as a key therapeutic signaling for the protection of alveolar epithelial barrier.

Hesperetin attenuates sepsis-induced intestinal barrier injury by regulating neutrophil extracellular trap formation via the ROS/autophagy signaling pathway. Food Funct 2023; 14:4213-4227.

Abstract
Background: Hesperetin (HES), one of the major flavonoids that has various biological activities, such as anti-inflammatory and antioxidant activities, may preserve the intestinal barrier during sepsis. However, the detailed mechanism remains unclear. Our previous studies confirmed that neutrophil extracellular traps (NETs) may jeopardize the intestinal barrier via a reactive oxygen species (ROS)-dependent pathway during sepsis. Therefore, we hypothesized that HES may inhibit NET formation and protect the intestinal barrier function during sepsis. Methods: Mice were pretreated with HES (50 mg kg-1) intraperitoneally for one week, and sepsis models were then induced using lipopolysaccharides (LPS) (10 mg kg-1). The mice were randomly divided into three groups: (1) sham group; (2) LPS group; and (3) HES + LPS group. Twenty-four hours after LPS injection, the serum and terminal ileum specimens were collected for subsequent studies. To detect ROS production and NET formation in vitro, human neutrophils were collected and incubated with phorbol-12-myristate-13-acetate (PMA) and various concentrations of HES. The level of autophagy was measured by an immunofluorescence assay and western blot analysis. TUNEL staining was utilized to analyze cell apoptosis. Results: The outcomes demonstrated that HES decreased inflammatory cytokine and myeloperoxidase (MPO) levels in serum and attenuated distant organ dysfunction in LPS-induced septic mice. Meanwhile, HES treatment reversed intestinal histopathological damage in septic mice, improving intestinal permeability and enhancing tight junction expression. Moreover, we found that neutrophil infiltration and NET formation in the intestine were suppressed during sepsis after HES pretreatment. In vitro, HES treatment reduced PMA-induced ROS production and NET formation, which were reversed by hydrogen peroxide (H2O2) administration. Notably, HES also inhibited NET formation by reducing the microtubule-associated protein light chain 3 (LC3)-II/LC3-I ratio (an indicator of autophagy) in PMA-induced neutrophils, which was reversed by rapamycin. Moreover, when autophagy was suppressed by chloroquine or induced by rapamycin, apoptosis in cells will be switched with autophagy. Conclusion: Taken together, these findings suggest that HES may inhibit NET formation in a ROS/autophagy-dependent manner and switch neutrophil death from NETosis to apoptosis, which reduced NETs-related intestinal barrier damage, providing a novel protective role in intestinal barrier dysfunction during sepsis.

Abstract
Colon cancer is a major cause of cancer-related death, with significantly increasing rates of incidence worldwide. The current study was designed to evaluate the anti-carcinogenic effects of hesperetin (HES) alone and in combination with capecitabine (CAP) on 1,2 dimethylhydrazine (DMH)-induced colon carcinogenesis in Wistar rats. The rats were given DMH at 20 mg/kg body weight (b.w.)/week for 12 weeks and were orally treated with HES (25 mg/kg b.w.) and/or CAP (200 mg/kg b.w.) every other day for 8 weeks. The DMH-administered rats exhibited colon-mucosal hyperplastic polyps, the formation of new glandular units and cancerous epithelial cells. These histological changes were associated with the significant upregulation of colon Ki67 expression and the elevation of the tumor marker, carcinoembryonic antigen (CEA), in the sera. The treatment of the DMH-administered rats with HES and/or CAP prevented these histological cancerous changes concomitantly with the decrease in colon-Ki67 expression and serum-CEA levels. The results also indicated that the treatments with HES and/or CAP showed a significant reduction in the serum levels of lipid peroxides, an elevation in the serum levels of reduced glutathione, and the enhancement of the activities of colon-tissue superoxide dismutase, glutathione reductase and glutathione-S-transferase. Additionally, the results showed an increase in the mRNA expressions of the anti-inflammatory cytokine, IL-4, as well as the proapoptotic protein, p53, in the colon tissues of the DMH-administered rats treated with HES and/or CAP. The TGF-β1 decreased significantly in the DMH-administered rats and this effect was counteracted by the treatments with HES and/or CAP. Based on these findings, it can be suggested that both HES and CAP, singly or in combination, have the potential to exert chemopreventive effects against DMH-induced colon carcinogenesis via the suppression of oxidative stress, the stimulation of the antioxidant defense system, the attenuation of inflammatory effects, the reduction in cell proliferation and the enhancement of apoptosis.

Abstract
Sepsis is a severe inflammatory condition that can cause organ dysfunction, including acute kidney injury (AKI). Hesperetin is a flavonoid aglycone that has potent antioxidant and anti-inflammatory properties. However, the effect of hesperetin on septic AKI has not yet been fully investigated. This study examined whether hesperetin has a renoprotective effect on lipopolysaccharide (LPS)-induced septic AKI. Hesperetin treatment ameliorated histological abnormalities and renal dysfunction in LPS-injected mice. Mechanistically, hesperetin attenuated LPS-induced oxidative stress, as evidenced by the suppression of lipid and DNA oxidation. This beneficial effect of hesperetin was accompanied by downregulation of the pro-oxidant NADPH oxidase 4, restoration of glutathione levels, and activation of antioxidant enzymes. This flavonoid compound also inhibited apoptotic cell death via suppression of p53-dependent caspase-3 pathway. Furthermore, hesperetin alleviated Toll-like receptor 4-mediated cytokine production and macrophage infiltration. Our findings suggest that hesperetin ameliorates LPS-induced renal structural and functional injury through suppressing oxidative stress, apoptosis, and inflammation.

Abstract
Acute pancreatitis (AP) is a disease characterized by local and systemic inflammation with an increasing incidence worldwide. Receptor-interacting serine/threonine protein kinase 3 (RIPK3), mixed-lineage kinase domain-like protein (MLKL), and innate immune cell macrophages have been reported to be involved in the pathogenesis of AP. However, the mechanisms by which RIPK3 and MLKL regulate pancreatic injury, as well as the interactions between injured pancreatic acinar cells and infiltrating macrophages in AP, remain poorly defined. In the present study, experimental pancreatitis was induced in C57BL/6J, Ripk3-/- and Mlkl-/- mice by cerulein plus lipopolysaccharide in vivo, and primary pancreatic acinar cells were also isolated to uncover cellular mechanisms during cerulein stimulation in vitro. The results showed that MLKL and its phosphorylated protein p-MLKL were upregulated in the pancreas of the mouse AP model and cerulein-treated pancreatic acinar cells, independent of its canonical upstream molecule Ripk3, and appeared to function in a cell death-independent manner. Knockout of Mlkl attenuated AP in mice by reducing the polarization of pancreatic macrophages toward the M1 phenotype, and this protective effect was partly achieved by reducing the secretion of CXCL10 from pancreatic acinar cells, whereas knockout of Ripk3 did not. In vitro neutralization of CXCL10 impaired the pro-M1 ability of the conditioned medium of cerulein-treated pancreatic acinar cells, whereas in vivo neutralization of CXCL10 reduced the polarization of pancreatic macrophages toward M1 and the severity of AP in mice. These findings suggested that targeting the MLKL-CXCL10-macrophage axis might be a promising strategy for the treatment of AP.

Abstract
Inflammatory bowel disease (IBD) is a chronic, non-specific inflammatory disease of the intestine that can be classified as ulcerative colitis (UC) and Crohn's disease (CD). Currently, the incidence of IBD is still increasing in developing countries. However, current treatments for IBD have limitations and do not fully meet the needs of patients. There is a growing demand for new, safe, and highly effective alternative drugs for IBD patients. Natural products (NPs) are used in drug development and disease treatment because of their broad biological activity, low toxicity, and low side effects. Numerous studies have shown that some NPs have strong therapeutic effects on IBD. In this paper, we first reviewed the pathogenesis of IBD as well as current therapeutic approaches and drugs. Further, we summarized the therapeutic effects of 170 different sources of NPs on IBD and generalized their modes of action and therapeutic effects. Finally, we analyzed the potential mechanisms of NPs for the treatment of IBD. The aim of our review is to provide a systematic and credible summary, thus supporting the research on NPs for the treatment of IBD and providing a theoretical basis for the development and application of NPs in drugs and functional foods.

Abstract
Citrus peel is rich in bioactive components, especially polyphenols, which are considered to have great potential in the prevention of intestinal diseases. The intestinal mucus barrier is the first defense against the invasion of foreign substances. In this study, we aimed to explore the possibility and mechanism of citrus peel in alleviating the mucus barrier damage in high-fat-diet (HFD) mice. We found that citrus peel powder (CPP) supplementation effectively reduced body weight, fat weight, intestinal permeability, hyperlipidemia, and systemic inflammation in HFD-fed mice. In particular, CPP increased the number of goblet cells, the protein expression of Mucin-2 (Muc2), and the thickness of the mucus layer, thereby strengthening the colonic mucus barrier function. Moreover, CPP supplementation also reduced the expression of endoplasmic reticulum stress (ERS) proteins (GRP78 and CHOP) and increased the expression of T-synthase (O-glycosylation rate-limiting enzyme) and its chaperone protein (Cosmc) in the colon of HFD-fed mice, which suggested that CPP could improve the abnormal protein folding and O-glycosylation of Muc2 during processing and modification. In summary, our study indicates that CPP plays an effective role in relieving mucus barrier damage by improving the production and properties of Muc2, providing new perspectives on the development of CPP as a dietary supplement for strengthening the intestinal barrier.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory disease of the intestine that presents clinically with abdominal pain, mucopurulent stools, and posterior urgency. The lesions of UC are mainly concentrated in the rectal and colonic mucosa and submucosa. For patients with mild to moderate UC, the best pharmacological treatment includes glucocorticoids, immunosuppressants, antibiotics, and biologics, but the long-term application can have serious toxic side effects. Currently, nearly 40% of UC patients are treated with herbal natural products in combination with traditional medications to reduce the incidence of toxic side effects. Flavonoid herbal natural products are the most widely distributed polyphenols in plants and fruits, which have certain antioxidant and anti-inflammatory activities. Flavonoid herbal natural products have achieved remarkable efficacy in the treatment of UC. The pharmacological mechanisms are related to anti-inflammation, promotion of mucosal healing, maintenance of intestinal immune homeostasis, and regulation of intestinal flora. In this paper, we summarize the flavonoid components of anti-ulcerative colitis and their mechanisms reported in the past 10 years, to provide a basis for rational clinical use and the development of new anti-ulcerative colitis drugs.

Adding a polyphenol-rich fiber bundle to food impacts the gastrointestinal microbiome and metabolome in dogs. Front Vet Sci 2023; 9:1039032. [PMID: 36744230 PMCID: PMC9896628 DOI: 10.3389/fvets.2022.1039032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Accepted: 12/09/2022] [Indexed: 01/21/2023] Open
Abstract
Introduction Pet foods fortified with fermentable fibers are often indicated for dogs with gastrointestinal conditions to improve gut health through the production of beneficial post-biotics by the pet's microbiome. Methods To evaluate the therapeutic underpinnings of pre-biotic fiber enrichment, we compared the fecal microbiome, the fecal metabolome, and the serum metabolome of 39 adult dogs with well-managed chronic gastroenteritis/enteritis (CGE) and healthy matched controls. The foods tested included a test food (TF1) containing a novel pre-biotic fiber bundle, a control food (CF) lacking the fiber bundle, and a commercially available therapeutic food (TF2) indicated for managing fiber-responsive conditions. In this crossover study, all dogs consumed CF for a 4-week wash-in period, were randomized to either TF1 or TF2 and fed for 4 weeks, were fed CF for a 4-week washout period, and then received the other test food for 4 weeks. Results Meaningful differences were not observed between the healthy and CGE dogs in response to the pre-biotic fiber bundle relative to CF. Both TF1 and TF2 improved stool scores compared to CF. TF1-fed dogs showed reduced body weight and fecal ash content compared to either CF or TF2, while stools of TF2-fed dogs showed higher pH and lower moisture content vs. TF1. TF1 consumption also resulted in unique fecal and systemic metabolic signatures compared to CF and TF2. TF1-fed dogs showed suppressed signals of fecal bacterial putrefactive metabolism compared to either CF or TF2 and increased saccharolytic signatures compared to TF2. A functional analysis of fecal tryptophan metabolism indicated reductions in fecal kynurenine and indole pathway metabolites with TF1. Among the three foods, TF1 uniquely increased fecal polyphenols and the resulting post-biotics. Compared to CF, consumption of TF1 largely reduced fecal levels of endocannabinoid-like metabolites and sphingolipids while increasing both fecal and circulating polyunsaturated fatty acid profiles, suggesting that TF1 may have modulated gastrointestinal inflammation and motility. Stools of TF1-fed dogs showed reductions in phospholipid profiles, suggesting fiber-dependent changes to colonic mucosal structure. Discussion These findings indicate that the use of a specific pre-biotic fiber bundle may be beneficial in healthy dogs and in dogs with CGE.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease generally characterized by chronic, persistent, recurrent, and non-specific ulcers of the intestine. Its main clinical manifestations include abdominal pain, diarrhea, and bloody stools. This disease is difficult to cure and even carries the risk of canceration. It has been listed as a modern refractory disease by the World Health Organization. Though a large amount of drugs are available for the inhibition of UC, the conventional treatment such as aminosalicylic acids, glucocorticoids, immunosuppressors, and biological agents possess certain limitations and serious side effects. Therefore, it is urgently needed for safe and effective drugs of UC, and natural-derived flavonols and flavanones showed tremendous potential. The present study concentrated on the progress of natural-derived flavonols and flavanones from edible and pharmaceutical plants for the remedy of UC over the last two decades. The potential pharmaceutical of natural-derived flavonols and flavanones against UC were closely connected with the modulation of gut microflora, gut barrier function, inflammatory reactions, oxidative stress, and apoptosis. The excellent efficacy and safety of natural flavonols and flavanones make them prospective drug candidates for UC suppression.

Abstract
Purpose Plant secondary metabolites are used to treat various human diseases. However, it is difficult to produce a large number of specific metabolites, which largely limits their medicinal applications. Many methods, such as drought and nutrient application, have been used to induce the biosynthetic production of secondary metabolites. Among these secondary metabolite-inducing methods, mechanical wounding maintains the composition of secondary metabolites with little potential risk. However, the effects of mechanical stress have not been fully investigated, and thus this method remains widely unused. Methods In this study, we used metabolomics to investigate the metabolites produced in the upper and lower leaves of Catharanthus roseus in response to mechanical wounding. Results In the upper leaves, 13 different secondary metabolites (three terpenoid indole alkaloids and 10 phenolic compounds) were screened using an orthogonal partial least squares discriminant analysis (OPLS-DA) score plot. The mechanical wounding of different plant parts affected the production of secondary metabolites. Specifically, when lower leaves were mechanically wounded, the upper leaves became a strong source of resources. Conversely, when upper leaves were injured, the upper leaves themselves became a resource sink. Changes in the source-sink relationship reflected a new balance between resource tradeoff and the upregulation or downregulation of certain metabolic pathways. Conclusion Our findings suggest that mechanical wounding to specific plant parts is a novel approach to increase the biosynthetic production of specific secondary metabolites. These results indicate the need for a reevaluation of production practices for secondary metabolites from select commercial plants.
