Résumé
Lipid metabolism disorder is an important risk factor for obesity,type 2 diabetes mellitus,non-alcoholic fatty liver disease and other chronic metabolic diseases.Micro RNAs(miRNAs)are short stranded RNA molecules with the size of 19 to 25 nucleotides that regulate lipid metabolism,within a number of physiological functions.Studies have shown that miRNAs can participate in the regulation of lipid metabolism by polyphenolic phytochemicals.In this paper,the mechanism of plant polyphenols improving lipid metabolism disorders and maintaining lipid balance through miRNA is summarized from the synthesis of triglyceride,fatty acid β oxidation,cholesterol efflux and cholesterol esterification,aiming to provide a new thought for the application and development of plant polyphenols to improve the diseases related to lipid metabolism disorders,and offer theoretical basis for the research and development of miRNA as a potential target for the prevention and treatment of diseases related to lipid metabolism disorders.
