The highest and lowest values for antioxidant enzymes and MDA concentration were observed in FP treatments (P<0.05). Also, the results showed that FP significantly decreased liver enzymes (ALT, AST) in the liver in comparison with HFD treatment (P<0.05). Plasma biochemical indices were investigated and the lowest amylase, ALP, fasting glucose, insulin, HOMA-IR, triglycerides, cholesterol, and inflammation cytokines (TNF-α, IL-6) were seen in the FP treatments which had a significant difference with HFD (P<0.05). Autophagy gene expression in the liver cells was affected by experimental diets and the lowest expression of Beclin-1 and Atg7 was observed in HFD and FP300 treatments. Interestingly, the highest expression of LC3-ɪ and P62 was seen in HFD and FP treatments, not in the control. Conclusion: Overall, the results of this experiment indicated that FPs extracted from Whiteleg shrimp at 50 °C improve the oxidative status, glucose metabolism, and autophagy gene expression and could be used as a useful nutritional strategy in fatty liver prevention.}, keywords = {Autophagy,Bioactive peptides,Fatty liver,Insulin,Oxidative Enzymes,Whiteleg shrimp}, url = {https://ijbms.mums.ac.ir/article_20781.html}, eprint = {https://ijbms.mums.ac.ir/article_20781_382f0bbf77caa56a3d855e12d9ee1d36.pdf} }
