摘要

MicroRNAs are endogenous small RNAs regulating the expression of their target genes on the post-transcriptional level. Up to now, loss-of-function mutants were generated in mice for only a few individual microRNAs in order to elucidate their functions in vivo.These .studies showed that these individual microRNAs play important roles in both.the cardiovascular and immune systems. We have recently shown that the miR-212/132 family has an indispensable function in the development of mammary gland in mice. The epithelial-stromal cell communications, necessary for the pubertal development of mammary gland, is regulated by the miR-212/132 family. This represents the first example for a microRNA function in a developmental process propagated through the organ microenvironment
