Abstract
Excessive apoptosis can kill normal cells and lead to liver damage, heart failure and neurodegenerative diseases. Polyphenols are secondary metabolites of plants that can interact with proteins to inhibit toxins and disease-related apoptosis. Bax is the major pro-apoptotic protein that disrupts the outer mitochondrial membrane to induce apoptosis, but limited studies have focused on the interaction between polyphenols and Bax and the associated anti-apoptotic mechanisms, especially at the atomic level. In this article, we collected 69 common polyphenols for active ingredient screening targeting Bax. Polyphenols with better and worse molecular docking scores were selected, and their anti-apoptosis effects were compared using the H2O2-induced HepG2 cell model. The interactions between the selected polyphenols and Bax protein were analyzed using molecular dynamics simulation to explore the molecular mechanism underlying the anti-apoptosis effect. Secoisolariciresinol diglucoside (SDG) and Epigallocatechin-3-gallate (EGCG) with the best affinity for Bax (-6.76 and -6.52 kcal/mol) reduced the expression of cytochrome c and caspase 3, decreasing the apoptosis rate from 52 to 11% and 12%. Molecular dynamics simulation results showed that Bim unfolded the α1-α2 loop of Bax, and disrupted the non-bond interactions between the loop (Pro-43, Glu-44 and Leu-45) and surface (Ile-133, Arg-134 and Met-137) residues, with binding free energy changed from -15.0 to 0 kJ/mol. The hydrogen bonds and van der Waals interactions formed between polyphenols and Bax prevented the unfolding of the loop. Taken together, our results proved that polyphenols can inhibit apoptosis by maintaining the unactivated conformation of Bax to reduce outer mitochondrial membrane damage.Communicated by Ramaswamy H.

Classical famous prescription of Jichuan decoction improved loperamide-induced slow transit constipation in rats through the cAMP/PKA/AQPs signaling pathway and maintained inflammatory/intestinal flora homeostasis. Heliyon 2024; 10:e21870. [PMID: 38192758 PMCID: PMC10771987 DOI: 10.1016/j.heliyon.2023.e21870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 10/30/2023] [Accepted: 10/30/2023] [Indexed: 01/10/2024] Open
Abstract
Introduction Jichuan decoction (JCD) is a well-known traditional Chinese medicinal formula that moistens the intestines and is widely used for the treatment of constipation in China. However, its effects and mechanisms in alleviating slow transit constipation (STC) in vivo remain unclear. We attempted to demonstrate the effect of JCD, with and without essential oil (VO), on intestinal transit and its underlying molecular mechanisms in rats with loperamide-induced STC. Materials and methods Water consumption, body weight, fecal water content, time to first melena excretion, and intestinal transit ratio of the animals were measured. 5-Hydroxytryptamine (5-HT), substance P (SP), vasoactive intestinal peptide (VIP), and interleukin-6 (IL-6) levels in the sera of rats were evaluated using ELISA. Hematoxylin and eosin and Periodic Acid-Schiff staining were used to determine intestinal tissue histology, while quantitative real-time PCR, western blotting, and immunohistochemical analysis were used to assess the relative expression levels of cAMP/PKA/AQPs pathway- and inflammation-related proteins. 16 S rDNA sequence analysis of rat feces was used to determine the diversity and abundance of the intestinal flora. Results The JCD groups showed reduced time to first melena excretion and expression of VIP and IL-6. The JCD groups, specifically JCD + VO groups, showed increased fecal water content, intestinal transit rate, and SP expression. Further, these groups showed improved histological characteristics of the colon, with no significant change in the index of immune organs or morphological characteristics of other organs. In addition, a significant decrease in the activation of the cAMP/PKA/AQPs signaling pathway in the colon tissue was observed in these groups, specifically the JCD + VO groups. Moreover, treatment with JCD, with or without VO, downregulated the expression of inflammatory factors and enriched the diversity of intestinal flora as evidenced by polymorphism analysis and the contents of Bacteroides, Lactobacillus, and Erysipelas, with the JCD + VO groups showing better therapeutic outcomes. Conclusion JCD improved loperamide-induced STC, and co-administration with VO exhibited better activity than sole JCD therapy. JCD may improve STC by inhibiting the cAMP/PKA/AQPs signaling pathway and maintaining inflammatory/intestinal flora homeostasis.

Abstract
Antioxidants from natural sources have long been of interest to researchers. In this paper, taking the traditional Tibetan medicine Ribes himalense as an example, an integrated approach was used to identify and isolate its chemical composition with free-radical-scavenging properties from its ethanol extract. First, the ethanol extract of Ribes himalense was pretreated using polyamide medium-pressure liquid chromatography (polyamide-MPLC), and the target fraction (Fr4) was obtained. Then, a combined HPLC mode was utilized to purify antioxidants in Fr4 under the guidance of an online HPLC-1,1-diphenyl-2-picrylhydrazyl (HPLC-DPPH) activity screening system. Finally, three antioxidants (3-caffeoylquinic acid methyl ester, rutin, and myricetin-3'-α-L-rhamnopyranoside) were isolated, and this is the first report of their presence in R. himalense. Further molecular docking studies showed that the antioxidants exhibited good binding with HO-1, Nrf2, and iNOS. In conclusion, this comprehensive approach is capable of extracting high-purity antioxidants from trace fractions of Ribes himalense and holds promise for future applications in the exploration of the chemical compositions and bioactivity of natural products.

Abstract
Oxidative stress, a condition involving an imbalance between reactive oxygen species (ROS) and antioxidants, is closely linked to epilepsy, contributing to abnormal neuronal excitability. This study introduces a novel fluorescent probe, the MDP probe, designed for the efficient detection of malondialdehyde (MDA), a critical biomarker associated with oxidative stress. The MDP probe offers several key advantages, including high sensitivity with a low detection limit of 0.08 μM for MDA, excellent selectivity for MDA even in the presence of interfering substances, and biocompatibility, making it suitable for cell-based experiments. The probe allows for real-time monitoring of MDA levels, enabling dynamic studies of oxidative stress. In vivo experiments in mice demonstrate its potential for monitoring MDA levels, particularly in epilepsy models, which could have implications for disease research and diagnosis. Overall, the MDP probe represents a promising tool for studying oxidative stress, offering sensitivity and specificity in cellular and in vivo settings. Its development opens new avenues for exploring the role of oxidative stress in various biological processes and diseases, contributing to advancements in healthcare and biomedical research.

Abstract
This study aimed to increase epigallocatechin gallate (EGCG) levels and attenuate the toxicity in Inulabritannica by fermentation using Lactobacillus plantarum SY12. The optimal medium was composed of 10 g of I. britannica, 4 g of xylose, 5 g of soytone, and 5 g of beef extract. The predicted value of EGCG was 237.327 μg/mL. To investigate damage in HepG2 cell lines by I. britannica extracts (IE) or fermented I. britannica extracts (FIE), cell viability, mitochondria membrane potential, the expression of apoptosis and autophagy genes, and chemical composition were measured. FIE increased cell viability, regulation of the gene expression (decreased p53, p62, p-ERK 1/2, and p-p38; increased CDK2 and CDK4) compared with IE. These results were explained by an increase in 1,3-dicaffeoylquinic acid and a decrease in 1-O-caffeoylquinic acid, 1-O-acetylbritannilactone, and ergolide in FIE. In conclusion, these results indicated that fermentation can mitigate the toxicity in I. britannica.

Caffeoylquinic acids isolated from Lonicera japonica Thunb. as TAK1 inhibitors protects against LPS plus IFN-γ-stimulated inflammation by interacting with KEAP1-regulated NRF2 activation. Biomed Pharmacother 2023; 165:115038. [PMID: 37418981 DOI: 10.1016/j.biopha.2023.115038] [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: 04/27/2023] [Revised: 06/12/2023] [Accepted: 06/20/2023] [Indexed: 07/09/2023] Open
Abstract
The transforming growth factor-β-activated kinase 1 (TAK1) phosphorylation promotes inflammation occurrence. Meanwhile, TAK1 directly interacts with KEAP1 and strenghtenes NRF2/HO-1 pathway downregulated-inflammation. Recently, we found that caffeoylquinic acids not only possessed powderful anti-inflammation function, but also attenuated oxidative damage through KEAP1/NRF2 pathway. Whereas it's rarely understood whether the anti-inflammatory activity were regulated by their interaction between TAK1 and NRF2. Herein, 34 caffeoylquinic acids including five new (2, 4-7) were systematically isolated and identified on the basis of spectroscopic evidence from Lonicera japonica Thunb. flower buds. Their inhibitory effects on inflammation induced by LPS plus IFN-γ were exerted substantial NO scavenging activity, and inhibited massive production of inflammatory cytokines and related proteins. Compound 3 (4F5C-QAME) exhibited the best anti-inflammation activity. 4F5C-QAME down-regulated the phosphorylation of TAK1, JNK, and c-JUN, thereby alleviated inflammation stimulated by LPS plus IFN-γ. Meanwhile, 4F5C-QAME could alleviate the interaction between TAK1 and KEAP1, inhibit the ubiquitination degradation of NRF2, activate NRF2/HO-1 signaling pathway, result in the increase in ROS elimination. Furthermore, 4F5C-QAME effectively protected against inflammation through direct inhibition of TAK1 phosphorylation. Based on these findings, 4F5C-QAME directly targeting TAK1 could be represented as a potential drug candidate for preventing/treating inflammatory diseases that regulated NRF2 activation through alleviating the interaction between TAK1 and KEAP1. Moreover, the regulatory mechanism of TAK1 on NRF2 activation under exogenous oxidative stress was revealed for the first time.

Abstract
One of the objectives of this study consists of the assessment of the antitumor activity of several extracts from three selected plant species: Xanthium spinosum L., Trifolium pratense L., and Coffea arabica L. and also a comparative study of this biological activity, with the aim of establishing a superior herbal extract for antitumor benefits. The phytochemical profile of the extracts was established by HPLC-MS analysis. Further, the selected extracts were screened in vitro for their antitumor activity and antioxidant potential on two cancer cell lines: A549-human lung adenocarcinoma and T47D-KBluc-human breast carcinoma and on normal cells. One extract per plant was selected for in vivo assessment of antitumor activity in an Ehrlich ascites mouse model. The extracts presented high content of antitumor compounds such as caffeoylquinic acids in the case of X. spinosum L. (7.22 µg/mL-xanthatin, 4.611 µg/mL-4-O-caffeoylquinic acid) and green coffee beans (10.008 µg/mL-cafestol, 265.507 µg/mL-4-O-caffeoylquinic acid), as well as isoflavones in the case of T. pratense L. (6806.60 ng/mL-ononin, 102.78 µg/mL-biochanin A). Concerning the in vitro results, the X. spinosum L. extracts presented the strongest anticancerous and antioxidant effects. In vivo, ascites cell viability decreased after T. pratense L. and green coffee bean extracts administration, whereas the oxidative stress reduction potential was important in tumor samples after T. pratense L. Cell viability was also decreased after administration of cyclophosphamide associated with X. spinosum L. and T. pratense L. extracts, respectively. These results suggested that T. pratense L. or X. spinosum L. extracts in combination with chemotherapy can induce lipid peroxidation in tumor cells and decrease the tumor viability especially, T. pratense L. extract.

Antioxidants (Basel) 2023; 12:antiox12040968.

Abstract
This study aimed to assess the protective effect of an extract of Lonicera japonica against particulate-matter (PM)2.5-induced pulmonary inflammation and fibrosis. The compounds with physiological activity were identified as shanzhiside, secologanoside, loganic acid, chlorogenic acid, secologanic acid, secoxyloganin, quercetin pentoside, and dicaffeoyl quinic acids (DCQA), including 3,4-DCQA, 3,5-DCQA, 4,5-DCQA, and 1,4-DCQA using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MSE). The extract of Lonicera japonica reduced cell death, reactive oxygen species (ROS) production, and inflammation in A549 cells. The extract of Lonicera japonica decreased serum T cells, including CD4+ T cells, CD8+ T cells, and total T helper 2 (Th2) cells, and immunoglobulins, including immunoglobulin G (IgG) and immunoglobulin E (IgE), in PM2.5-induced BALB/c mice. The extract of Lonicera japonica protected the pulmonary antioxidant system by regulating superoxide dismutase (SOD) activity, reduced glutathione (GSH) contents, and malondialdehyde (MDA) levels. In addition, it ameliorated mitochondrial function by regulating the production of ROS, mitochondrial membrane potential (MMP), and ATP contents. Moreover, the extract of Lonicera japonica exhibited a protective activity of apoptosis, fibrosis, and matrix metalloproteinases (MMPs) via TGF-β and NF-κB signaling pathways in lung tissues. This study suggests that the extract of Lonicera japonica might be a potential material to improve PM2.5-induced pulmonary inflammation, apoptosis, and fibrosis.

Abstract
Lonicera japonica (L. japonica) extract is rich in active substances, such as phenolic acids, essential oils, flavones, saponins, and iridoids, which have a broad spectrum of antioxidant, anti-inflammatory, and anti-microbial effect. Previous studies have demonstrated that L. japonica has a good regulatory effect on animal intestinal health, which can be used as a potential antibiotic substitute product. However, previous studies about intestinal health regulation mainly focus on experimental animals or cells, like mice, rats, HMC-1 Cells, and RAW 264.7 cells. In this review, the intestinal health benefits including antioxidant, anti-inflammatory, and antimicrobial activity, and its potential application in animal production were summarized. Through this review, we can see that the effects and mechanism of L. japonica extract on intestinal health regulation of farm and aquatic animals are still rare and unclear. Further studies could focus on the regulatory mechanism of L. japonica extract on intestinal health especially the protective effects of L. japonica extract on oxidative injury, inflammation, and regulation of intestinal flora in farm animals and aquatic animals, thereby providing references for the rational utilization and application of L. japonica and its extracts in animal production.

Abstract
Previous studies showed that interleukin-9 (IL-9) is involved in cardiovascular diseases, including hypertension and cardiac fibrosis. This study aimed to investigate the role of IL-9 in lipopolysaccharide (LPS)-induced myocardial cell (MC) apoptosis. Mice were treated with LPS, and IL-9 expression was measured and the results showed that compared with WT mice, LPS-treated mice exhibited increased cardiac Mø-derived IL-9. Additionally, the effects of IL-9 deficiency (IL-9-/-) on macrophage (Mø)-related oxidative stress and MC apoptosis were evaluated, the results showed that IL-9 knockout significantly exacerbated cardiac dysfunction, inhibited Nrf2 nuclear transfer, promoted an imbalance in M1 and M2 Møs, and exacerbated oxidative stress and MC apoptosis in LPS-treated mice. Treatment with ML385, a specific nuclear factor erythroid-2 related factor 2 (Nrf2) pathway inhibitor significantly alleviated the above effects in LPS-treated IL-9-/- mice. Bone marrow-derived Møs from wild-type (WT) mice and IL-9-/- mice were treated with LPS, and the differentiation and oxidative stress levels of Møs were measured. The effect of Mø differentiation on mouse MC apoptosis was also analyzed in vitro. The results showed that LPS-induced M1 Mø/M2 Mø imbalance and Mø-related oxidative stress were alleviated by IL-9 knockout but were exacerbated by ML385 treatment. The protective effects of IL-9 deficiency on the MC apoptosis mediated by LPS-treated Møs were reversed by ML-385. Our results suggest that deletion of IL-9 decreased the nuclear translocation of Nrf2 in Møs, which further aggravated Mø-related oxidative stress and MC apoptosis. IL-9 may be a target for the prevention of LPS-induced cardiac injury.

Abstract
OBJECTIVE We waimed to investigate whether H2S can relieve the myocardial fibrosis caused by doxorubicin through Keap1-Nrf2. METHODS Sprague-Dawley (SD) rats were randomly divided into four groups: normal control group (Control); DOX model group (DOX); H2S intervention model group (DOX+H2S); H2S control group (H2S). DOX and DOX+H2S group were injected with doxorubicin (3.0 mg/kg/time) intraperitoneally. Both of the Control group and H2S groups were given normal saline in equal volume, 2 weeks later, DOX+H2S and H2S group were controlled with NaHS (56 μmol/kg/d) through the abdominal cavity, while the Control and DOX group were injected with normal saline of the same dosage intraperitoneally. RESULTS Myocardial injury and myocardial cell apoptosis were significantly increased, the H2S content in myocardial tissue was remarkably down-regulated, the expression levels of MDA, Keap1, caspase-3, caspase-9, TNF-α, IL1β, MMPs and TIMP-1 in rat myocardial tissue was significantly up-regulated (P< 0.05), and the expression levels of GSH, NQO1, Bcl-2 were down-regulated compared with those of control group. The above results can be reversed by the DOX+H2S group. There is no statistically significant difference between the Control group and the H2S control group. CONCLUSIONS These results suggest that H2S can improve DOX-induced myocardial fibrosis in rats, and the keap1/Nrf2 signaling pathway, oxidative stress, inflammation, and apoptosis may be involved in the mechanism.

Ischemic postconditioning attenuates acute kidney injury following intestinal ischemia-reperfusion through Nrf2-regulated autophagy, anti-oxidation, and anti-inflammation in mice. FASEB J 2020; 34:8887-8901. [PMID: 32519766 DOI: 10.1096/fj.202000274r] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 05/06/2020] [Accepted: 05/10/2020] [Indexed: 12/12/2022]
Abstract
Intestinal ischemia-reperfusion (IIR) often occurs during and following major cardiovascular or gut surgery and causes significant organ including kidney injuries. This study was to investigate the protective effect of intestinal ischemic postconditioning (IPo) on IIR-induced acute kidney injury (AKI) and the underling cellular signaling mechanisms with focus on the Nrf2/HO-1. Adult C57BL/6J mice were subjected to IIR with or without IPo. IIR was established by clamping the superior mesenteric artery (SMA) for 45 minutes followed by 120 minutes reperfusion. Outcome measures were: (i) Intestinal and renal histopathology; (ii) Renal function; (iii) Cellular signaling changes; (iv) Oxidative stress and inflammatory responses. IPo significantly attenuated IIR-induced kidney injury. Furthermore, IPo significantly increased both nuclear Nrf2 and HO-1 expression in the kidney, upregulated autophagic flux, inhibited IIR-induced inflammation and reduced oxidative stress. The protective effect of IPo was abolished by the administration of Nrf2 inhibitor (Brusatol) or Nrf2 siRNA. Conversely, a Nrf2 activator t-BHQ has a similar protective effect to that of IPo. Our data indicate that IPo protects the kidney injury induced by IIR, which was likely mediated through the Nrf2/HO-1 cellular signaling activation.
