Abstract
- Purpose White adipose tissue (WAT) has positive effects on peripheral metabolism parameters and liver energy metabolism. This study aimed to explain the pharmacological mechanism of Qushi Huayu (QSHY) granules in the treatment of nonalcoholic fatty liver disease (NALFD) mice based on branched-chain amino acid (BCAA) catabolism and WAT browning. Patients and Methods Thirty C57BL/6J mice were randomly divided into a (Ctrl) control group, fed with a control diet, a NAFLD model group, fed with a high-fat and high-sugar (HFHS) diet, and a QSHY granules treatment (HFHS+QSHY) group, administered with QSHY granules. After 14 weeks of feeding, HFHS+QSHY group mice were administered QSHY granules through oral gavage for 6 weeks. The metabolic parameters were assessed, the circular and fecal BCAA content was observed, and liver and epididymal WAT (eWAT) were collected for pathological, quantitative real-time polymerase chain reaction, and Western blotting analyses. Results Compared with the HFHS group, mice in the HFHS+QSHY group demonstrated restored liver histological changes, ameliorated hepatocyte steatosis, and alleviated inflammatory cell infiltration. Consistent with the pathological changes, QSHY granules significantly reduced the elevated levels of liver triglycerides, and serum alanine aminotransferase, and it relieved hypercholesterolemia and insulin resistance in mice with HFHS-induced NAFLD. Furthermore, it corrected BCAA metabolic disorders in serum and feces and promoted the expression of BCAA catabolic genes in the eWAT of HFHS mice. QSHY granules also increased the expression of phosphorylated AMP-activated protein kinase (AMPK) protein, up-regulating the protein expression of the AMPK/SIRT1/UCP-1 pathway in the eWAT. Conclusion QSHY granules improved hepatic steatosis and corrected the BCAA disorder in NAFLD mice, and the related mechanisms regulated the AMPK/SIRT1/UCP-1 pathway and promoted WAT browning.
