The incidence of metabolic syndrome gradually multiplied with the change of dietary structure of high fat- high sugar in the population, bringing it as independent risk factors for tumors. Liver is an important organ of lipid metabolism. The main manifestations of metabolic syndrome are obesity and abnormal lipid metabolism, which are closely related to hepatocellular carcinoma occurrence. MicroRNA (miRNA) is an endogenous non-coding RNA that participates in the post-transcriptional regulation of target genes by binding to the 3'-UTR of mRNA. Research studies have found that abnormal miRNA expression can influence the pathogenesis of hepatocellular carcinoma via regulating lipid metabolism-related proteins in the liver. This article reviews and discusses the characteristics and pathogenesis of lipid metabolism disorder in hepatocellular carcinoma, and the mechanism by which miRNA regulates the occurrence and development of hepatocellular carcinoma through lipid metabolism-related proteins. Furthermore, it also provides a reliable theoretical foundation for the study of the pathogenesis of hepatocellular carcinoma.
随着人群高脂、高糖的膳食结构转变,代谢综合征发病率逐渐增加并成为肿瘤的独立危险因素。肥胖和脂代谢异常是代谢综合征的主要表现。肝脏是脂质代谢的重要器官,脂代谢紊乱和肝细胞癌(HCC)的发生密切相关。microRNA(miRNA)为内源性非编码RNA,通过与mRNA的3'非翻译区结合参与靶基因转录后调控,研究发现HCC中miRNA表达异常,可通过调控肝脏脂代谢相关蛋白从而影响HCC的发病过程。现就HCC中脂代谢特点及发病机制、miRNA如何通过脂代谢相关蛋白调控肝癌发生和发展的机制进行综述与探讨,为肝细胞癌发病机制的研究提供可靠的理论依据。.
