Downregulation of hepatic glucose-6-phosphatase-α in patients with hepatic steatosis.

Glucose-6-phosphate transporter (G6PT) and microsomal glucose-6-phosphatase-α (G6Pase-α) perform the terminal step in glycogenolysis and gluconeogenesis. Deficiency of these proteins leads to glycogen storage diseases. Partial inhibition of G6Pase in rats results in increased hepatic triglyceride content and de novo lipogenesis leading to hepatic steatosis.

Hepatic 11beta-HSD1 mRNA expression in fatty liver and nonalcoholic steatohepatitis.

Context: Nonalcoholic fatty liver disease represents the hepatic manifestation of the metabolic syndrome. Nonalcoholic steatohepatitis (NASH) is the progressive form of liver injury. The pathophysiology that leads to NASH is not well understood.
