Effect of gentiopicroside on endogenous formaldehyde homocysteine–pathway related proteins in rats with non-alcoholic steatohepatitis
Abstract
Background Non-alcoholic steatohepatitis (NASH) is a progressive form of non-alcoholic fatty liver disease (NAFLD) characterised by high prevalence, increasing incidence among younger individuals and poor prognosis. NASH pathophysiology is not completely understood, and at present, there are no viable pharmacological treatments for this condition in clinical practice. Gentiopicroside (GPS). Can alleviate NASH by reducing inflammatory responses, inhibiting oxidative stress and influencing blood lipid levels. Objective To examine the preventive and therapeutic effects of gentiopicroside (GPS) on proteins and metabolites related to the endogenous formaldehyde-homocysteine (FA-HCY) pathway as well as on oxidative stress in NASH rats. Methods A high-fat, high-sugar diet was used to create a NASH rat model, and the rats’ liver weight, body weight and liver index levels were measured. Oil red O and hematoxylin and eosin (HE) stainings were used to detect pathological alterations in the rat livers. Serum biochemical kits were used to identify biochemical markers in the rat serum. Markers linked to oxidative stress and metabolites associated with the endogenous FA-HCY pathway index were identified using Enzyme-linked immunosorbent assays (ELISA) kits. Gas chromatography was employed to measure the amount of endogenous FA in the liver and serum. Western blotting and real-time (RT) PCR were used to determine the relative expression levels of proteins and mRNAs associated with the…
