Compared to wild-type and Tm4sf5−/− knockout mice, hepatocyte-specific TM4SF5-overexpressing Alb-TGTm4sf5−Flag (TG) mice showed abnormal food-intake behavior during the mouse-inactive daytime, increased apelin expression, increased food intake, and higher levels of NASH features. The gene discussed is ALB; the disease is metabolic dysfunction-associated steatohepatitis.
