肥胖相关基因与叉头转录因子在非酒精性脂肪肝大鼠模型肝脏中的表达
Expression of obesity-related gene and forkhead transcription factors in liver of nonalcoholic fatty liver disease rat model
摘要
Abstract
Objective To research the obesity-related gene (FTO) and forkhead transcription factors O1 (FoxO1) protein expression level in the livers of non-alcoholic fatty liver disease(NAFLD) rat model. Methods The animal model of NAFLD in rats was prepared by feeding high energy and high fat feed. Then the rat blood and liver tissue were collected for detecting the liver index and blood biochemical indexes, including triglycerides (TG), total cholesterol (TC), alanine aminotransferase (AST), aspartate aminotransferase(ALT) ,alkaline phosphatase(ALP),high-density lipoprotein (HDL) and low density lipoprotein(LDL) ;the liver pathological examination was performed;FTO protein and Fox O1 protein expression levels in rat liver were detected by using the immunohistochemical assay. Results The rat liver weight,body weight and liver index after 8 weeks in the model group were higher than those in the control group,the difference was statistically significant (P<0.05);the levels of AST, ALT, LDL, ALP, TG and TC in the model group were higher than those in the control group,the difference was statistically significant (P<0. 05),the HDL level in the model group was lower than that in the control group, the difference was statistically significant (P<0.05) ;the model group produced steatosis and inflammation in hepatic lobule part,while the control group had no these lesions;the FTO prot ein and FoxO1 protein expression levels in liver of the model group were higher than those in the control group,the difference was statistically significant (P<0.05). Conclusion FTO and FoxO1 interaction may disturb the normal energy and fat metabolism.关键词
