Association between nonalcoholic fatty liver disease and malignant transformation of hepatocytes

摘要:
非酒精性脂肪性肝病(NAFLD)是除酒精和其他明确的肝损伤因素所致的以弥漫性肝细胞大泡性脂肪变性为主,肝脏脂质蓄积过多的临床病理综合征,包括单纯性脂肪肝、演变的脂肪性肝炎和肝硬化。随着NAFLD发病率的不断上升,其在肝细胞癌(HCC)中的发病风险也在增加,但其确切的机制尚不清楚。总结了NAFLD中脂质积累、各种相关细胞、蛋白、激素、代谢产物等与肝细胞恶性转化之间关系,以及NAFLD、HCC和脂肪代谢三者间的联系,为临床上预防HCC提供新的思路。
Abstract:Nonalcoholic fatty liver disease( NAFLD) is a clinicopathological syndrome characterized by diffuse macrovesicular steatosis and excessive lipid accumulation in the liver due to nonalcoholic reasons and other specific factors for liver injury,including simple fatty liver,nonalcoholic steatohepatitis,and liver cirrhosis. With the increasing incidence of NAFLD,the risk of hepatocellular carcinoma( HCC) is also increasing,but the exact mechanism remains unknown. This paper summarizes the roles of lipid accumulation,related cells,proteins,hormones,and metabolites in malignant transformation of hepatocytes,as well as the relationship between NAFLD,HCC,and lipid metabolism,and provides a new perspective for the prevention of HCC in clinical practice.
