Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gentiana kurroo Royle is a medicinal plant mentioned as Traymana in Ayurveda. In the folklore, it is used to cure fever, stomach ache, skin diseases and liver disorders. However, limited reports are available on the therapeutic potential of Gentiana kurroo Royle against alcohol-induced liver damage. AIM OF THE STUDY To assess the effectiveness of the hydroethanolic extract of Gentiana kurroo Royle rhizome (GKRE) against alcohol-induced liver injury and explore the mechanism of action. MATERIALS AND METHODS GKRE was characterized using UHPLC-QTOF-MS/MS. The binding affinity of the identified compound was studied in silico. In vitro studies were performed in the Huh-7 cell line. An acute oral toxicity study (2 g/kg BW) of GKRE was done in rats following OECD 420 guidelines. In the efficacy study, rats were treated with 50% ethanol (5 mL/kg BW, orally) for 4 weeks, followed by a single intraperitoneal dose of CCl4 (30%; 1 mL/kg BW) to induce liver injury. After 4th week, the rats were treated with GKRE at 100, 200 and 400 mg/kg BW doses for the next fifteen days. The biochemical and antioxidant parameters were analyzed using commercial kits and a biochemistry analyzer. Histopathology, gene and protein expressions were studied using qRT PCR and western blotting. RESULTS Thirteen compounds were detected in GKRE. Few compounds showed a strong interaction with the fibrotic and inflammatory proteins in silico. GKRE reduced (p < 0.05) the ethanol-induced ROS production and inflammation in Huh-7 cells. The acute oral toxicity study revealed no adverse effect of GKRE in rats at 2 g/kg BW. GKRE improved (p < 0.05) the body and liver weights in ethanol-treated rats. GKRE improved (p < 0.05) the mRNA levels of ADH, SREBP1c and mitochondrial biogenesis genes in the liver tissues. GKRE also improved (p < 0.05) the liver damage markers, lipid peroxidation and levels of antioxidant enzymes in the liver. A reduced severity (p < 0.05) of pathological changes, fibrotic tissue deposition and caspase 3/7 activity were observed in the liver tissues of GKRE-treated rats. Further, GKRE downregulated (p < 0.05) the expression of fibrotic (TGFβ, αSMA and SMADs) and inflammatory markers (TNFα, IL6, IL1β and NFκB) in the liver. CONCLUSION GKRE showed efficacy against alcohol-induced liver damage by inhibiting oxidative stress, apoptosis, inflammation and fibrogenesis in the liver.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 121:155085. [PMID: 37757709 DOI: 10.1016/j.phymed.2023.155085] [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: 04/19/2023] [Revised: 09/03/2023] [Accepted: 09/11/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND Lamiophlomis Herba (LH) is a valuable traditional medicinal plant found on the Qinghai-Tibetan Plateau that promotes blood circulation, removes blood stasis, and has antibacterial and anti-inflammatory properties. The main components of LH are iridoid glycosides, phenethyl alcohol glycosides, flavonoids, and polysaccharides. PURPOSE To investigate the mechanism of the anti-liver fibrosis effects of LH and screen for its bioactive compounds. STUDY DESIGN Screening LH marker components and validating the LH anti-liver fibrosis mechanism. METHODS The active ingredients of LH were identified using UPLC-Q-TOF-MS, and HotMap combined with principal components analysis (PCA) was used to screen for marker components. Network pharmacology and molecular docking techniques were used to predict the potential anti-fibrotic targets of LH. Immunofluorescence, enzyme-linked immunosorbent assay (ELISA), real-time PCR (RT-PCR), and western blotting were used for experimental validation and mechanistic studies. RESULTS Fifteen compounds that actively contributed to the cluster were identified as marker compounds. Acteoside, 8-O-acetyl shanzhiside methyl ester (8-O-ASME), Luteolin, Shanzhiside Methyl ester (SME), Loganin, Loganate were the main active components. Network pharmacology and molecular docking studies have shown that LH might improve liver fibrosis, inflammation, and oxidative stress, which might be related to key targets such as PTGS2, MAPK, EGFR, AKT1, SRC, Fn1, Col3a1, Col1a1, and PC-III. The results of ELISA, RT-PCR and western blot experiments showed that Acteoside, 8-O-ASME, Luteolin, SME, Loganin, Loganate, and the LH group could reduce the levels of fibronectin, Col1a1, Col3a1, α-SMA, Col-Ⅳ, LN, and PC-Ⅲ. CONCLUSION LH improves liver fibrosis induced by HSC-T6 cells and inhibits the deposition of extracellular matrix (ECM) in hepatocytes, resulting in a decrease in the degree of liver fibrosis and a good anti-liver fibrosis effect.

Abstract
The liver is a critical system for metabolism in human beings, which plays an essential role in an abundance of physiological processes and is vulnerable to endogenous or exogenous injuries. After the damage to the liver, a type of aberrant wound healing response known as liver fibrosis may happen, which can result in an excessive accumulation of extracellular matrix (ECM) and then cause cirrhosis or hepatocellular carcinoma (HCC), seriously endangering human health and causing a great economic burden. However, few effective anti-fibrotic medications are clinically available to treat liver fibrosis. The most efficient approach to liver fibrosis prevention and treatment currently is to eliminate its causes, but this approach's efficiency is too slow, or some causes cannot be fully eliminated, which causes liver fibrosis to worsen. In cases of advanced fibrosis, the only available treatment is liver transplantation. Therefore, new treatments or therapeutic agents need to be explored to stop the further development of early liver fibrosis or to reverse the fibrosis process to achieve liver fibrosis resolution. Understanding the mechanisms that lead to the development of liver fibrosis is necessary to find new therapeutic targets and drugs. The complex process of liver fibrosis is regulated by a variety of cells and cytokines, among which hepatic stellate cells (HSCs) are the essential cells, and their continued activation will lead to further progression of liver fibrosis. It has been found that inhibiting HSC activation, or inducing apoptosis, and inactivating activated hepatic stellate cells (aHSCs) can reverse fibrosis and thus achieve liver fibrosis regression. Hence, this review will concentrate on how HSCs become activated during liver fibrosis, including intercellular interactions and related signaling pathways, as well as targeting HSCs or liver fibrosis signaling pathways to achieve the resolution of liver fibrosis. Finally, new therapeutic compounds targeting liver fibrosis are summarized to provide more options for the therapy of liver fibrosis.

Life Sci 2023; 316:121437. [PMID: 36702203 DOI: 10.1016/j.lfs.2023.121437] [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: 11/16/2022] [Revised: 01/03/2023] [Accepted: 01/20/2023] [Indexed: 01/25/2023]
Abstract
Obesity is an epidemic and a growing public health concern worldwide. It is one of the significant risk factors for developing chronic kidney disease. In the present study, we evaluated the preventive effect of green tea catechins (GTC) against obesity-induced kidney damage and revealed the underlying molecular mechanism of action. Various green tea catechins were quantified in the catechins-rich fraction using HPLC. In vitro, the palmitic and oleic acid-treated NRK-52E cells showed reduced fat accumulation and modulated expressions of PPARγ, CD36, and TGFβ after GTC treatment. In vivo, rats were fed with a high-fat diet (HFD), and the effect of GTC was assessed at 150 and 300 mg/kg body weight doses. HFD-fed rats showed a significant reduction in weight gain and improved serum creatinine, urea, and urine microalbumin levels after GTC treatment. The improved adipokines and insulin levels in GTC treated groups indicated the insulin-sensitizing effect. Histopathology revealed reduced degenerative changes, fibrous tissue deposition, and mesangial matrix proliferation in GTC treated groups. GTC treatment also downregulated the gene expressions of lipogenic and inflammatory factors and improved the altered expressions of CD36 and PPARγ in the kidney tissue. Further, GTC prevented gut dysbiosis in rats by promoting healthy microbes like Akkermansia muciniphila and Lactobacillus reuteri. Faecal metabolome revealed reduced saturated fatty acids, and improved amino acid levels in the GTC treated groups, which help to maintain gut health and metabolism. Overall, GTC prevented obesity-induced kidney damage by modulating PPARγ/CD36 signaling and maintaining gut health in rats.
