| Title: | HCBP6 deficiency exacerbates glucose and lipid metabolism disorders in non-alcoholic fatty liver mice. |
| Abstract: | BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), which often accompanied by metabolic syndrome, such as obesity, diabetes and dyslipidemia, has become a global health problem. Our previous results show that HCV core protein binding protein 6 (HCBP6) could maintain the triglyceride homeostasis in liver cells. However, the role of HCBP6 in NAFLD and its associated metabolic disorders remains incompletely understood. METHODS: Hepatic HCBP6 expression was determined by qRT-PCR, Western blot and immunohistochemistry analysis. HCBP6 knockout (HCBP6-KO) mice were constructed and fed a high-fat diet (HFD) to induce NAFLD. The effects of HCBP6 on glucose and lipid metabolism were measured by HE staining, qRT-PCR, Western blot and GTT. Wild-type and HCBP6-KO mice kept on a HFD were treated with ginsenosides Rh2, and HE staining and GTT were used to study the function of Rh2 in metabolism disorders. RESULTS: HCBP6 is reduced in HFD-fed mice. HCBP6 deficiency increased the body weight, aggravated fatty liver and deteriorated lipid homeostasis as well as glucose homeostasis in HFD-induced mouse model of NAFLD. Moreover, HCBP6-KO mice failed to maintain body temperature upon cold challenge. Mechanistically, HCBP6 could regulate lipolysis and fatty acid oxidation via activation of AMKP in vivo. In addition, HCBP6 expression was upregulated by ginsenosides Rh2. Accordingly, ginsenosides Rh2 administrations improved HFD-induced fatty liver and glucose tolerance. CONCLUSIONS: These findings indicated that HCBP6 is essential in maintaining lipid and glucose homeostasis and body temperature. HCBP6 augmented by ginsenosides Rh2 may be a promising therapeutic strategy for the treatment of metabolic disorders in NAFLD mice. |
