MiR-378a-5p participates in the regulation of CDK1 expression. (A) There is a potential seed sequence of miR-378a-5p in the 3′UTR of CDK1, the putative seed sequences for the 3′-UTR of CDK1 were highly conserved in different species. (B) qRT-PCR, (C,D) western blot were used to determine CDK1 mRNA and protein expression levels and p21 protein levels in VSMCs transfected with miR-378a-5p mimics (25 nmol/L), inhibitor (100 nmol/L), NC (25 nmol/L) and inNC (25 nmol/L) after PDGF-BB stimulation, data are presented as mean ± SEM, ∗p < 0.05, ∗∗p < 0.01, and ∗∗∗p < 0.001. (E) Typical fluorescence photomicrograph by laser scan confocal microscopy, scale bar = 20 μm. The photographs of nuclei (blue) and CDK1 (green) fluorescence were taken under a same field and then were merged. (F) Real-time PCR validation of CDK1-associated mRNAs identified by RIP, data are presented as mean ± SEM. ∗∗p < 0.01.
