Effects of blueberry on the expression of TNF-α-R1 and SREBP-1c in acute alcoholic fatty liver
Objective:To observe the effect of blueberry on the mRNA and protein expression of tumor necrosis factor(TNF)-α-R1 and sterol regulatory element-binding protein(SREBP)-1c in acute alcoholic fatty liver(AFL). Methods:A total of 50 male C57BL/6 mice were randomly divided into normal control group(A),model group(B),high dose blueberry group(20.0 g/kg)(C),low dose blueberry group(10.0 g/kg)(D),and tiopronin group(30 mg/kg)(E),10 in each group. All mice except those in group A were fed with the Lieber-DeCarli diet for 15 d and were gastrogavaged with alcohol on the 16th day to induce AFL model. Mice in groups C-E were respec-tively administered with corresponding drugs by gastrogavage,once per day for 15 d. Detection of alanine transaminase(ALT),aspar-tate transaminase(AST),triglycerides(TG) and cholesterol(TC) in serum were performed by an automatic biochemical analyser. The level of TNF-α in serum was determined by an enzyme-linked immunosorbent assay. The morphological changes of the liver tissue were observed by HE staining. The mRNA and protein expressions of TNF-α-R1 and SREBP-1c in the liver tissue were determined by RT-PCR and Western blot,respectively. Results:Compared with those in group B,the levels of ALT,AST,TG,TC and TNF-α in serum were significantly lower(P=0.000 or P=0.025),the degree of hepatic steatosis and degen-erative necrosis were significantly improved in groups C-E(P=0.000),and the mRNA and protein expression of TNF-α-R1 and SREBP-1c were significantly lower in groups C-E(all P=0.000). Conclusion:Blue berry has a good protective effect on acute AFL in mice,the mechanism is probably related to the inhibition of the expression of TNF-α-R1 and SREBP-1c.
