Abstract
The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) may cause significant intestinal alteration and inflammation and lead to the occurrence of inflammatory diseases resembling duodenal ulcers. Astragaloside IV (AS-IV) is a glycoside of cycloartane-type triterpene isolated from the dried root of Astragalus membranaceus (Fisch.) Bge. (family Fabaceae), and has been used for ameliorating the NSAID-induced inflammation in the small intestine. The present study aimed to investigate the effects of AS-IV on indomethacin (IND)-induced inflammation in the small intestine of rats and its underlying mechanisms. Hematoxylin-eosin (H&E) staining, transmission and scanning electron microscopy were carried out to observe the surface morphology and ultrastructure of the small intestinal mucosa. Immunofluorescence and ELISA tests were employed to detect the expressions of NLRP3, ASC, caspase-1, and NF-κB proteins, as well as inflammatory factors IL-1β and IL-18, to uncover potential molecular mechanisms responsible for mitigating small intestinal inflammation. The results demonstrated that AS-IV significantly decreased the ulcer index, improved the surface morphology and microstructure of the small intestinal mucosa, and increased mucosal blood flow. Molecular docking revealed a strong and stable binding capacity of AS-IV to NLRP3, ASC, caspase-1, and NF-κB proteins. Further experimental validation exhibited that AS-IV markedly decreased levels of IL-1β and IL-18, and inhibited the protein expression of NLRP3, ASC, caspase-1, and NF-κB. Our data demonstrate that AS-IV ameliorates IND-induced intestinal inflammation in rats by inhibiting the activation of NLRP3 inflammasome and reducing the release of IL-1β and IL-18, thereby representing a promising therapy for IND-induced intestinal inflammation.

Int Immunopharmacol 2024; 131:111814. [PMID: 38479159 DOI: 10.1016/j.intimp.2024.111814] [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: 10/07/2023] [Revised: 02/07/2024] [Accepted: 03/05/2024] [Indexed: 04/10/2024]
Abstract
OBJECTIVE The increasing global prevalence of ulcerative colitis (UC) underscores the imperative to explore novel therapeutic approaches. Traditional Chinese medicine has historically shown potential in addressing this ailment. The current study aimed to elucidate the functional attributes and underlying mechanisms of isofraxidin, a coumarin derivative from Acanthopanax, in the context of UC. METHODS A murine model of dextran sodium sulfate (DSS)-induced UC was established, and we conducted a comprehensive assessment of the influence of isofraxidin on UC symptomatology, colonic histopathological manifestations, the inflammatory response, and apoptosis. The potential receptor of isofraxidin was initially identified through the Target database and molecular docking analysis. Subsequent in vivo and in vitro experiments were conducted to determine the effects of isofraxidin on the identified receptor and associated signaling pathways. Transfection was used to examine the receptor's role in the regulatory mechanism of isofraxidin. RESULTS Isofraxidin reduced UC symptoms and colonic histopathological impairments. Furthermore, isofraxidin ameliorated the DSS-induced inflammatory response and apoptosis in tissues. S1PR1 was identified as a target of isofraxidin and effectively suppressed activation of the IL-17 signaling pathway. Intriguingly, cellular experiments indicated that overexpression of S1PR1 counteracted the protective effect of isofraxidin. DISCUSSION In summary, our investigation revealed that isofraxidin could modulate S1PR1 and regulate the IL-17 signaling pathway, thus ameliorating DSS-induced UC. These findings establish a robust foundation for considering isofraxidin as a prospective therapeutic intervention to treat UC.

[PMID: 38321559 PMCID: PMC10845565 DOI: 10.1186/s40001-024-01695-w] [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: 10/19/2022] [Accepted: 01/24/2024] [Indexed: 02/08/2024] Open
Abstract
OBJECTIVE To explore the mechanism of huankuile (HKL) in colon injury repair in rats with ulcerative colitis (UC). METHODS Fifty SPF Wistar male rats were divided randomly into a normal group, a negative control group, an HKL intervention group ('HKL group') and a 5-aminosalicylic acid intervention group ('5-ASA group'). After 14 days of intervention with corresponding drugs, pathological scores were obtained using the results of immunohistochemical staining; morphological changes were observed by hematoxylin-eosin staining, and the mRNA expression levels of tumour necrosis factor-α (TNF-α), matrix metalloproteinase 9 (MMP9) and interleukin-13 (IL-13) were detected by real-time quantitative PCR. RESULTS After the successful construction of the rat model, it was compared with the rats in the normal group. In the negative group, it was found that the expression of TNF-α and MMP9 was significantly increased in the colonic mucosal epithelia of the rats, the pathological score was significantly increased (P < 0.05), and the mRNA expression levels of TNF-α, MMP9 and IL-13 were increased (P < 0.05). After treatment with HKL, the colonic morphology of the rats returned to normal, the expression of TNF-α and MMP9 in the colonic mucosal epithelium of the rats returned to normal, the pathological score grade was significantly reduced (P < 0.05), and the mRNA expression levels of TNF-α, MMP9 and IL-13 were reduced; these results were largely consistent with those of the normal group, with no statistically significant difference. CONCLUSION HKL effectively improved the general symptoms and tissue injury in UC rats, and the therapeutic effect was better than that of 5-ASA group. Ulcerative colitis in rats increased the expression of TNF-α, MMP9 and IL-13. HKL repaired UC-induced colonic injury in rats by decreasing the expression of TNF-α, MMP9 and IL-13.

Abstract
This study aims to explore the effects of Astragaloside IV (AS-IV) on abnormal behaviors, intestinal microbiota, intestinal T-immune balance, and fecal metabolism of a model of depression in rats. Herein, we integrally applied 16S rRNA sequencing, molecular biological techniques, and 1H NMR-based fecal metabolomics to demonstrate the antidepression activity of AS-IV. The results suggested that AS-IV regulated the depression-like behaviors of rats, which are presented by an increase of body weight, upregulation of sucrose preference rates, and a decrease of immobility time. Additionally, AS-IV increased the abundances of beneficial bacteria (Lactobacillus and Oscillospira) in a model of depression in rats. Moreover, AS-IV regulated significantly the imbalance of Th17/Treg cells, and the abnormal contents of both anti-inflammatory factors and pro-inflammatory factors. Besides, fecal metabolomics showed that AS-IV improved the abnormal levels of short-chain fatty acids and amino acids. Collectively, our research supplemented new data, supporting the potential of AS-IV as an effective diet or diet composition to improve depression-like behaviors, dysfunctions of microbiota, imbalance of T immune, and the abnormality of fecal metabolome. However, the causality of the other actions was not proven because of the experimental design and the methodology used. The current findings suggest that AS-IV could function as a promising diet or diet composition to alleviate depressed symptoms.

Abstract
The increased α-synuclein (α-syn)-dependent activation of CD4 T cells leads to the progressive loss of dopaminergic (DA) neurons in the substantia nigra (SN) in Parkinson's disease (PD). Astragaloside IV (AS-IV) protects DA neurons against neuroinflammation. The effects of AS-IV on CD4 T-cell-mediated immune responses in PD remain unknown. Rotenone (ROT) injected unilaterally into the substantia nigra pars compacta (SNc) of rats induced PD. AS-IV (20 mg/kg) was intraperitoneally injected once a day for 14 days. The limb hanging test and rotarod test were performed to evaluate the alteration of behavior at 4 and 6 weeks. Total gastrointestinal transit tests were performed at 4 weeks. Western blotting was used to detect the expression of proinflammatory cytokine proteins. Immunofluorescence staining was conducted to test the expression and localization of major histocompatibility complex class II (MHCII), cleaved caspase-1 and α-syn in astrocytes. Flow cytometry analysis, immunohistochemistry and immunofluorescence staining were used to measure the expression of CD4 T-cell subsets in the SN. The application of AS-IV protected against the loss of DA neurons and behavioral deficits in ROT-induced PD rat models. AS-IV administration inhibited the aggregation of α-syn in DA neurons and the expression of proinflammatory cytokines such as TNF-α, IL-18, IL-6 and IL-1β. AS-IV decreased the activation of CD4 T cells and three CD4 T-cell subsets: Tfh, Treg and Th1. AS-IV interrupted the ROT-induced interaction between astrocytes and CD4 T cells and the colocalization of MHCII and α-syn in astrocytes. AS-IV inhibited the expression of α-syn in astrocytes and the colocalization of α-syn and cleaved caspase-1 in astrocytes. AS-IV prevents the loss of DA neurons in PD by inhibiting the activation of α-syn-specific CD4 T cells, which is regulated by MHCII-mediated antigen presentation in astrocytes.

Abstract
Saponins are extracted from different parts of plants such as seeds, roots, stems, and leaves and have a variety of biological activities including immunomodulatory, anti-inflammatory effects, and hypoglycemic properties. They demonstrate inherent low immunogenicity and possess the capacity to effectively regulate both the innate and adaptive immune responses. Plant saponins can promote the growth and development of the body's immune organs through a variety of signaling pathways, regulate the activity of a variety of immune cells, and increase the secretion of immune-related cytokines and antigen-specific antibodies, thereby exerting the role of immune activity. However, the chemical structure of plant saponins determines its certain hemolytic and cytotoxicity. With the development of science and technology, these disadvantages can be avoided or reduced by certain technical means. In recent years, there has been a significant surge in interest surrounding the investigation of plant saponins as immunomodulators. Consequently, the objective of this review is to thoroughly examine the immunomodulatory properties of plant saponins and elucidate their potential mechanisms, with the intention of offering a valuable point of reference for subsequent research and advancement within this domain.

Abstract
Ginsenoside Rg1 (G-Rg1) has various pharmacological properties including antiobesity, immunomodulatory, and anti-inflammatory effects. This study aimed to explore the therapeutic effects and underlying mechanisms of G-Rg1 on colitis complicated by obesity. The results indicate that G-Rg1 effectively alleviates colitis in obese mice and improves serum lipid levels and liver function. Importantly, G-Rg1 improved the composition of gut microbiota in obese mice with colitis, with increases in alpha diversity indexes Sobs, Ace, and Chao, a significant down-regulation of the relative abundance of Romboutsia, and a significant up-regulation of Rikenellaceae_RC9_gut_group, Lachnospiraceae_NK4A136_group, Enterorhabdus, Desulfovibrio, and Alistipes. Meanwhile, G-Rg1 improved lipid metabolism in the colonic contents of obese mice with colitis. Additionally, G-Rg1 significantly reduced the percentages of helper T (Th)1, Th17, central memory T (TCM), and effector memory T (TEM) cells in obese mice with colitis while significantly increasing Naïve T and Th2 cells. In conclusion, G-Rg1 could be a promising therapeutic option for alleviating obesity complicated by colitis through regulation of the gut microbiota and lipid metabolism as well as Th1/Th2/Th17 cell differentiation.

Sci Rep 2023; 13:22077. [PMID: 38087032 PMCID: PMC10716149 DOI: 10.1038/s41598-023-49421-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 12/07/2023] [Indexed: 12/18/2023] Open
Abstract
Chronic obstructive pulmonary disease (COPD) is a severe condition that leads to premature mortality and places a significant financial burden on healthcare systems. An adjunctive therapy in COPD includes the simultaneous administration of astragalus injection and ambroxol hydrochloride. Despite its widespread use, the effectiveness of this combined approach in COPD treatment has not been systematically evaluated. Thus, we conducted a systematic review and meta-analysis to assess the efficacy of combining astragalus injection with ambroxol hydrochloride as an adjuvant treatment for COPD. Six electronic databases were used to search for relevant randomized controlled trials, and data analysis was conducted using Review Manager 5.4. A total of 14 randomized controlled trials were included, involving 1070 patients who met the criteria. The results of the meta-analysis indicated that the combination of astragalus injection with ambroxol hydrochloride as an adjuvant treatment can improve various clinical parameters in patients with COPD compared to conventional treatment alone. These parameters include the clinical effective rate (OR = 5.44, 95% CI 3.51-8.43, I2 = 0%), partial pressure of oxygen in artery (MD = 1.12, 95% CI 0.87-1.36, I2 = 5%), partial pressure of carbon dioxide in artery (MD = - 1.43, 95% CI - 1.65 to - 1.21, I2 = 0%), forced expiratory volume in one second (MD = 0.30, 95% CI 0.18-0.42, I2 = 0%), percentage of forced expiratory volume in one second (MD = 16.18, 95% CI 12.60-19.76, I2 = 82%), forced vital capacity (MD = 0.33, 95% CI 0.21-0.45, I2 = 36%), hemoglobin (MD = - 16.17, 95% CI - 20.84 to - 11.51, I2 = 29%), and the ratio of forced expiratory volume in one second to forced vital capacity (MD = 2.51, 95% CI - 0.05 to 5.06, I2 = 0%). The combination of astragalus injection and ambroxol hydrochloride could be a selection of COPD patients as an adjuvant treatment. However, further validation is required to evaluate the effectiveness of combining astragalus injection and ambroxol hydrochloride as an adjunctive treatment for patients with COPD.

Int Immunopharmacol 2023; 125:111026. [PMID: 37866315 DOI: 10.1016/j.intimp.2023.111026] [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: 07/27/2023] [Revised: 09/24/2023] [Accepted: 10/04/2023] [Indexed: 10/24/2023]
Abstract
Triple-negative breast cancer (TNBC) is the most aggressive subtype and has a poor response to treatment due to an immunosuppressive microenvironment. Chinese Medicine effective constituents such as oxymatrine (Om) and astragaloside IV (As) have shown promise in cancer treatment by providing anti-fibrosis and immune-enhancing effects. However, the potential combined effect of Om and As on TNBC and its mechanism is still uncertain. This study focuses on exploring the impact of Om and As on enhancing the immunosuppressive microenvironment of TNBC and uncovering the potential mechanism behind it. In this study, a trans-Cancer associated fibroblasts (CAFs) infiltration system of T cells was utilized to investigate the potential benefits of Om, while the impact of As on the morphology and quantity of mitochondria in T cells was examined in a co-culture system with tumor cells. Further to investigate the combined effects of Om and As on tumor suppression and immunosuppressive microenvironment improvement, this study established an in situ TNBC mouse model with 4 T1-luc. In vitro, our findings indicate that Om can effectively suppress the activation of CAFs by downregulating the expression of FAP and α-SMA, and also promoting the infiltration of T cells trans CAFs. It was discovered that the mitochondrial activity of T cells could be improved by increasing the number of mitochondria and cristae. In vivo, the optimal ratio of Om and As (2:1) was found to increase the apoptosis rate of tumor cells in a co-culture system and enhance the infiltration of CD4+ and CD8+ T cells, as confirmed by Flow Cytometry results. Our study suggests that Om and As could enhance the immune system's ability to treat TNBC by improving the infiltration and increasing the anti-tumor function of TILs. This intervention may lead to a promising therapeutic direction for the treatment of TNBC.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory bowel disease, which is characterized by inflammation, with many symptoms including diarrhea, abdominal pain, bloody stool, and weight loss. It is difficult to completely cure and promising therapeutic drug candidates are urgently needed. Citropten, a coumarin-like compound found in traditional Chinese medicine such as Finger Citron Fruit, notopterygium root and citrus peel, has been shown to inhibit the proliferation of tumor cells, protect against depression and suppress the production of inflammatory mediators. In this study, we demonstrated that citropten could alleviate dextran sulfate sodium (DSS)-induced acute and recurrent colitis in mice, with significant improvement in body weight loss, disease activity index, shortened colon length and histological changes. Moreover, citropten dramatically decreased the production of pro-inflammatory mediators in colon tissues and effectively suppressed the proportion of Th17 cells in spleen. Mechanism investigations revealed that citropten significantly inhibited the activation of NF-κB and JAK/STAT3 signaling pathways, thus leading to decreased inflammation, Th17 cells and alleviative colitis. These findings provide novel insights into the anti-colitis effect of citropten, which may be a promising drug candidate for treatment of IBD.

Abstract
The incidence of ulcerative colitis (UC) is increasing annually. There are few treatments for UC patients, and some drugs have serious side effects. Sea cucumber peptide (SCP) has anti-inflammatory, antioxidant and other biological activities, and various sea cucumber species are in pharmaceutical development. However, relevant studies on the effects of SCP on UC progression are still lacking. In this study, a mouse model of acute colitis was induced by 3% dextran sulfate (DSS), and the effect of 500 mg/kg SCP on colitis was investigated. The results showed that SCP can alleviate DSS-induced colon damage and intestinal barrier damage. SCP significantly inhibited the expression of inflammatory factors and oxidative stress in UC mice. SCP reversed the intestinal microbiota dysregulation induced by DSS, inhibited the growth of Sutterella, Prevotella_9 and Escherichia-Shigella harmful bacteria, and increased the abundance of Lachnospiraceae_NK4A136_group. At the same time, SCP treatment significantly inhibited the LPS-induced polarization of M1 macrophages, which may be mediated by two monopeptides, IPGAPGVP and TGPIGPPGSP, via FPR2. In conclusion, SCP can protect against colitis by modulating the intestinal microbiota composition and the intestinal barrier and inhibiting the polarization of M1 macrophages.

World J Gastroenterol 2023; 29:5226-5239. [PMID: 37901446 PMCID: PMC10600958 DOI: 10.3748/wjg.v29.i36.5226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 08/26/2023] [Accepted: 09/07/2023] [Indexed: 09/20/2023] Open
Abstract
BACKGROUND Restoration of immune homeostasis by targeting the balance between memory T helper (mTh) cells and memory follicular T helper (mTfh) cells is a potential therapeutic strategy against ulcerative colitis (UC). Because of its anti-inflammatory and immunomodulatory properties, curcumin (Cur) is a promising drug for UC treatment. However, fewer studies have demonstrated whether Cur can modulate the mTh/mTfh subset balance in mice with colitis. AIM To explore the potential mechanism underlying Cur-mediated alleviation of colitis induced by dextran sulfate sodium (DSS) in mice by regulating the mTh and mTfh immune homeostasis. METHODS Balb/c mice were administered 3% and 2% DSS to establish the UC model and treated with Cur (200 mg/kg/d) by gavage on days 11-17. On the 18th d, all mice were anesthetized and euthanized, and the colonic length, colonic weight, and colonic weight index were evaluated. Histomorphological changes in the mouse colon were observed through hematoxylin-eosin staining. Levels of Th/mTh and Tfh/mTfh cell subsets in the spleen were detected through flow cytometry. Western blotting was performed to detect SOCS-1, SOCS-3, STAT3, p-STAT3, JAK1, p-JAK1, and NF-κB p65 protein expression levels in colon tissues. RESULTS Cur effectively mitigates DSS-induced colitis, facilitates the restoration of mouse weight and colonic length, and diminishes the colonic weight and colonic weight index. Simultaneously, it hinders ulcer development and inflammatory cell infiltration in the colonic mucous membrane. While the percentage of Th1, mTh1, Th7, mTh7, Th17, mTh17, Tfh1, mTfh1, Tfh7, mTfh7, Tfh17, and mTfh17 cells decreased after Cur treatment of the mice for 7 d, and the frequency of mTh10, Th10, mTfh10, and Tfh10 cells in the mouse spleen increased. Further studies revealed that Cur administration prominently decreased the SOCS-1, SOCS-3, STAT3, p-STAT3, JAK1, p-JAK1, and NF-κB p65 protein expression levels in the colon tissue. CONCLUSION Cur regulated the mTh/mTfh cell homeostasis to reduce DSS-induced colonic pathological damage, potentially by suppressing the JAK1/STAT3/SOCS signaling pathway.

Abstract
Ulcerative colitis (UC) is a chronic, non-specific disease of unknown etiology. The disease develops mainly in the rectum or colon, and the main clinical symptoms include abdominal pain, diarrhea, and purulent bloody stools, with a wide variation in severity. The specific causative factors and pathogenesis of the disease are not yet clear, but most scholars believe that the disease is caused by the interaction of genetic, environmental, infectious, immune, and intestinal flora factors. As for the treatment of UC, medications are commonly used in clinical practice, mainly including aminosalicylates, glucocorticoids, and immunosuppressive drugs. However, due to the many complications associated with conventional drug therapy and the tendency for UC to recur, there is an urgent need to discover new, safer, and more effective drugs. Natural compounds with biodiversity and chemical structure diversity from medicinal plants are the most reliable source for the development of new drug precursors. Evidence suggests that glycosides may reduce the development and progression of UC by modulating anti-inflammatory responses, inhibiting oxidative stress, suppressing abnormal immune responses, and regulating signal transduction. In this manuscript, we provide a review of the epidemiology of UC and the available drugs for disease prevention and treatment. In addition, we demonstrate the protective or therapeutic role of glycosides in UC and describe the possible mechanisms of action to provide a theoretical basis for preclinical studies in drug development.

Abstract
Diabetic cardiomyopathy (DCM), one of the major complications of type 2 diabetes, is a leading cause of heart failure and death in advanced diabetes. Although there is an association between DCM and ferroptosis in cardiomyocytes, the internal mechanism of ferroptosis leading to DCM development remains unknown. CD36 is a key molecule in lipid metabolism that mediates ferroptosis. Astragaloside IV (AS-IV) confers various pharmacological effects such as antioxidant, anti-inflammatory, and immunomodulatory. In this study, we demonstrated that AS-IV was able to recover the dysfunction of DCM. In vivo experiments showed that AS-IV ameliorated myocardial injury and improved contractile function, attenuated lipid deposition, and decreased the expression level of CD36 and ferroptosis-related factors in DCM rats. In vitro experiments showed that AS-IV decreased CD36 expression and inhibited lipid accumulation and ferroptosis in PA-induced cardiomyocytes. The results demonstrated that AS-IV decreased cardiomyocyte injury and myocardial dysfunction by inhibiting ferroptosis mediated by CD36 in DCM rats. Therefore, AS-IV regulated the lipid metabolism of cardiomyocytes and inhibited cellular ferroptosis, which may have potential clinical value in DCM treatment.

Abstract
INTRODUCTION This study aimed to investigate the effect of etanercept in psoriasis and its underlying mechanism. METHODS Female mice were treated with imiquimod (IMQ) to induce psoriasis, and intraperitoneally administered etanercept (0.1-0.4 mg/ml). The RAW264.7 cells were treated with LPS and IFN-γ to polarize to M1, and were treated with IL-13 and IL-4 to polarize to M2. RESULTS In our study, Etanercept markedly reduced the psoriasis area and severity index scores, and epidermal thickness of mice induced by IMQ. In addition, etanercept reduced the levels of TNF-α and IL-6/12/23, and enhanced the levels of IL-4/10, reduced Th17/Treg ratio and facilitated the polarization of macrophages to M2 in psoriasis model mice. Furthermore, etanercept inhibited the JAK/STAT3 pathway and increased the protein levels of SOCS1 and SOCS3. CONCLUSIONS In conclusion, our findings indicated that etanercept could inhibit the JAK/STAT3 pathway to reduce Th17/Treg ratio and promote M2 polarization, thereby alleviating psoriasis of mice.

Abstract
BACKGROUND Ulcerative colitis (UC) is the most prevalent chronic inflammatory immune bowel disease. The modernization of lifestyle accompanied by the stress to cope with the competition has resulted in a new range of complications where stress became a critical contributing factor for many diseases, including UC. Hence there is an urgent need to develop a dual role in curtailing both systemic and neuroinflammation. Perillyl alcohol (POH) is a natural essential oil found in lavender, peppermint, cherries etc and has been widely studied for its strong anti-inflammatory, antioxidant and anti-stress properties. HYPOTHESIS/PURPOSE POH regulates the various inflammatory signaling cascades involved in chronic inflammation by inhibiting farnesyltransferase enzyme. Several studies reported that POH could inhibit the phosphorylation of NF-κB, STAT3 and promote the endogenous antioxidant enzymes like Nrf2 via farnesyltransferase enzyme inhibition. Also, the effects of POH against UC is not known yet. Thus, this study aims to explore the anti-ulcerative properties of POH on stress aggravated ulcerative colitis in C57BL/6 mice. METHODS Ulcerative colitis was induced by duel exposure of chronic restraint stress (day 1 to day 28) and 2.5% dextran sulphate sodium (day8 to day14) in mice. POH treatment 100 and 200 mg/kg was administred from day14 ti day28 following oral route of administration. Disease activity index, colonoscopy, western blot analysis and histological analysis, neurotransmitter analysis and Gene expression studies were perofomerd to asses the anti-colitis effects of POH. RESULTS The treatment reversed the oxidative stress and inflammatory response by inhibiting TLR4/NF-kB pathway, and IL-6/JAK2/STAT3 pathway in both isolated mice colons and brains. The inhibition of these pathways resulted in a decrease in pro-inflammatory cytokines like IL-6, IL-1β and TNF-α. The treatment improved the physiological and histological changes with decreased ulcerations as examined by colonic endoscopy and Haematoxylin and Eosin staining. The treatment also improved the behavior response as it increased mobility time which was reduced by chronic restrained stress. This was due to increased satiety neurotransmitters like dopamine and serotonin and decreased cortisol in mice brains. CONCLUSION These results infer that POH has significant anti-colitis activity on chronic restraint stress aggravated DSS-induced UC in mice.
