MicroRNAs (miRNAs) can regulate a variety of biological functions such as fat and cholesterol synthesis, translocation, and utilization by regulating degradation or by inhibiting target mRNA translation. In this study, the target gene of miR-21-3p was analyzed through bioinformatics, which predicted Elovl5. Furthermore, miR-21-3p was verified for regulation of triglyceride expression. The results showed that luciferase activity was significantly lower in cells cotransfected with miR-21-3p and Elovl5 reporter vector, pmiR-RB-REPORT-Elovl5-WT, than in cells with miR-21-3p and reporter control vectors, pmiR-RB-REPORT-Elovl5-mut and pmiR-RB-REPORT-Elovl5-si, indicating that target sites exist in the 3'UTR of Elovl5...
