miR-30b-5p directly targets SIRT1 in macrophages. (A) miR-30b-5p target sequence in the 3’UTR of Sirt1. (B) Relative activity of firefly luciferase and Renilla luciferase after co-transfection with mimics and plasmids expressing wild-type or mutated target sites. (C) RT-qPCR analysis of Sirt1 mRNA level of cells treated with the miR-30b-5p antagonist. (D) RT-qPCR analysis of Sirt1 mRNA level of cells treated with miR-30b-5p mimics. (E) Immunoblot analysis of SIRT1 protein level of cells treated with miR-30b-5p mimics and antagonists. #1:mimics control group; #2: miR-30b-5p mimics group; #3: antagonists control group; #4: miR-30b-5p antagonists group. The data represent at least three independent experiments and are presented as mean ± SD. *p<0.05; and ***p<0.001.
