What is Androgen Receptor Functions in Pericentral Hepatocytes to Decrease Gluconeogenesis and Avoid Hyperglycemia and Obesity in Male Mice about?

## Background: Although the impact of hepatic androgen receptor (ar) pathway on liver pathogenesis was documented, its physiological function in normal liver is remained unclear. this study aims to investigate if hepatic ar acts on metabolism, the major liver function, using a hepatic-specific ar-transgenic (h-artg) mouse model. ## Methods: We established the albumin promoter driven h-artg mice and included wild type (wt) and h-arko mice for study. the body weight, specific metabolic parameters and results from various tolerance tests were compared in different groups of mice fed a chow diet, from 2 to 18 months of age. glucose feeding and insulin treatment were used to study the expression and zonal distribution pattern of ar and related genes in liver at different prandial stages. ## Results: The body weight of h-artg mice fed a chow diet was 15 % lower than that of wild-type mice, preceded by lower blood glucose and liver triglyceride levels caused by ar reduced hepatic gluconeogenesis. the opposite phenotypes identified in h-arko and castrated h-artg mice support the critical role of activated ar in decreasing gluconeogenesis and triglyceride levels in liver. hepatic ar acting
