The recombinant Tarim red deer HGF protein successfully reduced serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in mice, increased serum albumin (ALB) levels, decreased hepatic steatosis and triglyceride (TG) levels, lowered hepatic malondialdehyde (MDA) levels, and increased the levels of the antioxidants glutathione (GSH) and superoxide dismutase (SOD) in the liver. The gene discussed is GPT; the disease is Hepatic steatosis.
