Mouse-specific up-regulation of Ccnb1 expression by miR-199a-5p in keratinocyte.

ABSTRACT: MicroRNA (miRNA) are a class of single-stranded, small non-coding RNA that regulate various biological processes, including skin and hair cycle regulation, by modulating the expression of specific genes at the post-transcriptional level. Recently, several studies reported that miRNA directly or indirectly up-regulate target genes. Previously, we performed microarray analysis to identify the target genes of miR-199a-5p in a mouse skin keratinocyte cell line and detected more than 200 genes whose expression was significantly increased by miR-199a-5p overexpression (> 1.5-fold). In this study, we further investigated these genes and found that cyclin B1 (Ccnb1) expression was positively regulated by miR-199a-5p in keratinocyte. Moreover, Ccnb1 expression was inversely correlated
