Excessive dietary fat deposition in the liver leads to hepatic steatosis, which, in turn, triggers oxidative stress and inflammatory response in hepatocytes.17,18 HFD significantly increased the levels of serum ALT (Figure 3a) and AST (Figure 3b) in mice, suggesting liver injury, whereas treatment with B. theta effectively reversed the liver injury. This evidence concerns the gene GPT and Hepatic steatosis.
