1. Mir-27a regulates wnt3a and kitlg expression in Cashmere goats with different coat colors.

MicroRNAs(miRNAs) regulate and control gene expression at the post-transcriptional level by base pairing with its target gene 3'UTR, resulting in degradation of the target mRNA or inhibition of its translation. The previous high-throughput sequencing results indicated that miR-27a was involved in...
