摘　　要：The liver plays a major role in the regulation , glucose, lipid and energy metabolism. Increasd hepatic fat deposit is a very common feature in obese, insulin-resistant patients, in metabolic syndrome, alcoholic steatohepatitis （ASH） and nonalchoholic fatty liver disaseas （NAFLD）. As a central organ for whole body lipid metabolism, disruption of the normal mechanisms for synthesis, transport and removal/ metabolism of long-chain fatty acids and triglycerides are the basis for the development of fatty liver. The exact mechanisms that link hepatic lipid accumulation, impaired glucose metabolism, and insulin resistance are unknown, but increasing evidence suggest that nuclear transcription factors play important roles. Members of the nuclear receptor superfamily, especially the peroxisome proliferator-activated receptors （PPARs） and the liver X receptor （LXR）, other factors such as sterol regulatory element binding proteins （SREBPs）, carbohydrate- response element-binding protein （ChREBP）, and nuclear transcription fator-κB （NF-κB） have emerged as dominant regulators of these processes, but the relative role of each of these factors in fatty liver disease is still undefined.The liver plays a major role in the regulation , glucose, lipid and energy metabolism.
