Abstract: In this study, a specific inhibitor antagomirs of microRNA-499(miR-499) was injected to reveal the regulatory effect of microRNA-499 on lipid metabolism related genes of Pelodiscus sinensis. Fifteen healthy juvenile Pelodiscus sinensis were selected and randomly divided into control group, saline group and miR-499 antagomirs group, respectively. After 3 days of continuous injection at the same time, triglyceride and total cholesterol in serum and liver were determined, and the expression levels of miR-499 and lipid metabolism related genes in liver were determined by real-time quantitative PCR. The results showed that the injection of miR-499 antagomirs increased the expression levels of thyroid hormone response protein gene(THRSP) and sodium/iodine co-transporter gene(NIS), and decreased the expression level of carnitine palmitoyl transferase 1 gene(CPT1) compared with the control group and the saline group (P<0.05). The injection of miR-499 antagomirs affected the expression level of lipid metabolism genes, and miR-499 was related to fat production and fatty acid β-oxidation of Pelodiscus sinensis.

Key words: Pelodiscus sinensis, miRNA-499, antagomirs, lipid metabolism, gene expression
