Exp Gerontol 2024; 185:112351. [PMID: 38135257 DOI: 10.1016/j.exger.2023.112351] [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: 02/22/2023] [Revised: 12/10/2023] [Accepted: 12/18/2023] [Indexed: 12/24/2023]
Abstract
BACKGROUND Intestinal stem cells (ISCs) are the reservoir source of various types of intestinal cells, and the decline of stem cell function in the gut may be a potential factor for aging-related disease. The present study aimed to explore the regulatory mechanisms of Panax ginseng C.A.Meyer (Araliaceae, Panax genus) that could restore gut aging by enhancing intestinal function and regulating ISCs in aging mice based on the Wnt/β-catenin signaling pathway. METHODS A total of 60 ICR male mice were randomly divided into control, model, metformin, and ginseng water decoction (GWD) 3.6, 1.8, and 0.9 g/kg groups. The aging model was induced by 1 % D-galactose (s.c. 0.1 mL/10 g) for 28 days. Moreover, GWD was given to aging mice intragastrically (i.g.) once a day for 28 successive days. The learning memory ability, pathological status, and function in the ileum tissue, the activity of digestive enzymes, and short-chain fatty acid (SCFA) content in the colon were evaluated, and the related mechanism was investigated. RESULTS Ginseng can decrease the escape latency time and increase the swimming speed and the number of crossing platforms in aging mice. Moreover, the pathology of ileum tissue improved, the length of the intestinal villi increased, and the width of the villi and the depth of the crypts decreased. The activities of trypsin, α-amylase, and lipase increased in duodenal content and intestinal mucosa. In the colon, the content of SCFA, such as acetic acid, propionic acid and butyric acid, increased, indicating that ginseng significantly improves intestinal function impairment. The mRNA expressions and protein levels of β-catenin, C-myc, GSK-3β, Lgr5, and Olfm4 were upregulated in the ginseng group. CONCLUSIONS Ginseng improves intestinal function and regulates the function of ISCs in order to protect intestinal health by activating the Wnt/β-catenin signaling pathway in aging mice.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 105:154351. [PMID: 35908522 DOI: 10.1016/j.phymed.2022.154351] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 07/03/2022] [Accepted: 07/19/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Ban-xia-xie-xin-tang (BXXXT) has been applied in treating metabolic diseases, such as nonalcohol fatty liver disease, diabetes mellitus, and obesity. However, the underlying molecular mechanism of BXXXT in treating diabetes mellitus is unknown. PURPOSE To clarify the underlying molecular mechanism of BXXXT in alleviating hepatic steatosis in high-fat diet (HFD)-fed mice. METHODS After 12 weeks of HFD treatment, mice were administered BXXXT for 4 weeks. The main chemical components of BXXXT were identified by UPLC-TQ-MS/MS. Indicators associated with insulin resistance and lipid metabolism were detected. The effect of improving glucose and lipid metabolism between BXXXT and the different components was compared. Differentially expressed genes (DEGs) were identified by hepatic transcriptomics. Key DEGs and proteins were further detected by real-time quantitative polymerase chain reaction, western blotting, immunohistochemistry, and immunofluorescence staining. LDs and mitochondria were detected by transmission electron microscopy. RESULTS First of all, our data demonstrated that the capacity to improve glucose and lipid metabolism for BXXXT was significantly superior to different components of BXXXT. BXXXT was found to improve HFD-induced insulin resistance. Moreover, BXXXT decreased weight, serum/hepatic triglycerides, total cholesterol, and FFAs to alleviate HFD-induced hepatic steatosis. According to the results of the hepatic transcription, Cidea and Cidec were identified as critical DEGs for promoting LD fusion and reducing FFAs β-oxidation in mitochondria and peroxisome resulting in hepatic steatosis, which was reversed by BXXXT. CONCLUSION BXXXT ameliorates HFD-induced hepatic steatosis and insulin resistance by increasing Cidea and Cidec-mediated mitochondrial and peroxisomal fatty acid oxidation, which may provide a potential strategy for therapy of NAFLD and T2DM.

Ginsenoside Rg1 protects mice against 2,3,7,8-tetrachlorodibenzo-p-dioxin-induced liver injury by inhibiting CYP1A1 through the aryl hydrocarbon receptor. JOURNAL OF ETHNOPHARMACOLOGY 2022; 294:115394. [PMID: 35595219 DOI: 10.1016/j.jep.2022.115394] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 04/26/2022] [Accepted: 05/13/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Panax ginseng C. A. Meyer (ginseng) is a widely used traditional Chinese medicine that has played a beneficial role in the treatment of various diseases, including liver diseases. Ginsenoside Rg1 is a saponin isolated and purified from ginseng that exerts protective effects on the liver in some liver injury models. 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a ubiquitous dioxin found mostly in food products that causes liver injury and other human diseases. Although significant efforts have been made to reduce the burden of liver disease, there is still a lack of effective treatment methods. AIM OF THE STUDY Although ginsenoside Rg1 was reported to inhibit TCDD-mediated cytochrome P450 1A1 (CYP1A1) induction in HepG2 cells, we sought to verify its hepatoprotective effects and elucidate its mechanism in a TCDD-induced liver injury model in mice. MATERIAL AND METHODS The mouse liver injury model was established by intraperitoneal TCDD injection, followed by treatment with various doses of ginsenoside Rg1 (50, 100, and 200 mg/kg). Clinical indicators of liver injury, such as an increase in serum aspartate aminotransferase and alanine aminotransferase levels, as well as histopathological changes were evaluated. RESULTS The common clinical indicators of liver injury were detected following TCDD injection, including an increase in serum alanine aminotransferase and aspartate aminotransferase levels, increased relative liver weight, and histopathological changes. Following treatment with ginsenoside Rg1, the levels of aspartate aminotransferase and alanine aminotransferase decreased significantly, and the liver histology was improved. In addition, ginsenoside Rg1 competitively inhibited TCDD-induced Cyp1a1 mRNA transcription through the modulation of aryl hydrocarbon receptor (AhR) nuclear translocation. CONCLUSION Ginsenoside Rg1 is a potent partial AhR agonist that has potential as an effective medication for protecting against TCDD-associated liver injury.

Brown adipose tissue activation by ginsenoside compound K treatment ameliorates polycystic ovary syndrome. Br J Pharmacol 2022; 179:4563-4574. [PMID: 35751868 DOI: 10.1111/bph.15909] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Revised: 04/28/2022] [Accepted: 05/06/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND AND PURPOSE Polycystic ovary syndrome (PCOS) is a common metabolic and endocrine disease affecting women of reproductive age. Due to its complex etiology, there is no effective cure for PCOS currently. Brown adipose tissue (BAT) activity is significantly decreased in PCOS patients and BAT activation has beneficial effects on PCOS animal models. Here, we investigated the therapeutic effect of ginsenoside compound K (CK) on an animal model of PCOS and its mechanism of BAT activation EXPERIMENTAL APPROACH: Primary brown adipocyte, Db/Db mice and dehydroepiandrosterone (DHEA)-induced PCOS rats were used. The core body temperature, oxygen consumption, energy metabolism related gene and protein expression were assessed to identify the function of CK on energy metabolism. Estrous cycle, serum sex hormone, ovarian steroidogenic enzyme gene expression and ovarian morphology were evaluated following CK treatment. KEY RESULTS Our results indicated that CK treatment could significantly protect against body weight gain in Db/Db mice via BAT activation. Furthermore, we found that CK treatment could normalize hyperandrogenism, estrous cyclicity, normalize steroidogenic enzyme expression and decrease the number of cystic follicles in PCOS rats. Interestingly, as a potential endocrine intermediate, C-X-C motif chemokine ligand-14 protein (CXCL14) was significantly upregulated following CK administration. In addition, exogenous CXC14 supplementation was found to reverse DHEA-induced PCOS in a phenotypically similar manner to CK treatment. CONCLUSION AND IMPLICATIONS In summary, CK treatment significantly activates BAT, increases CXCL14 expression and ameliorates PCOS. These findings suggest that CK might be a potential drug candidate for PCOS treatment.

Ginsenoside-Rg1 acts as an IDO1 inhibitor, protects against liver fibrosis via alleviating IDO1-mediated the inhibition of DCs maturation. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 84:153524. [PMID: 33667840 DOI: 10.1016/j.phymed.2021.153524] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 01/19/2021] [Accepted: 02/17/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Indoleamine 2,3-dioxygenase 1 (IDO1) has been reported as a hallmark of hepatic fibrosis. Ginseng Rg1(G-Rg1) is a characterized bioactive component isolated from a traditional Chinese medicinal herb Panax ginseng C. A. Meyer (Ginseng) that used in China widely. However, the anti-hepatic fibrosis property of G-Rg1 and the underlying mechanisms of action are poorly reported. PURPOSE Here, we researched the effect of G-Rg1 on experimental liver fibrosis in vivo and in vitro. STUDY DESIGN AND METHODS We applied a CCL4-induced liver fibrosis in mice (wild-type and those overexpressing IDO1 by in vivo AAV9 vector) and HSC-T6 cells to detect the anti-hepatic fibrosis effect of G-Rg1 in vivo and in vitro. RESULTS We found that G-Rg1 reduced serum levels of AST and ALT markedly. Histologic examination indicated that G-Rg1 dramatically improved the extent of liver fibrosis and suppressed the hepatic levels of fibrotic marker α-SMA in vivo and in vitro. The proliferation of HSC-T6 was significantly inhibited by G-Rg1 in vitro. Both TUNEL staining and flow cytometry demonstrated that G-Rg1 attenuated the levels of hepatocyte apoptosis in fibrotic mice. Additionally, G-Rg1 up-regulated the maturation of hepatic DCs via reducing the expression level of hepatic IDO1, which played an inverse role in the maturation of DCs. Furthermore, oral administration of G-Rg1 ameliorated IDO1 overexpression-induced worsen liver fibrosis as well as IDO1 overexpression-mediated more apparent inhibition of maturation of DCs. CONCLUSION These results suggest that G-Rg1, which exerts its antifibrotic properties via alleviating IDO1-mediated the inhibition of DCs maturation, may be a potential therapeutic drug in treating liver fibrosis.
