miR-138 Function and Its Targets on Mouse Mammary Epithelial Cells / 生物化学与生物物理进展

ABSTRACT

miRNA was 20～25 nt endogenous non-coding RNA. miRNAs are encoded small RNAs that hybridize with messenger RNAs, resulting in degradation or translational inhibition of targeted transcripts. In order to investigate the function of miR-138 on mouse mammary epithelial cells, technique for gene silencing-miRNA inhibitor (anti-miRNA) was applied to make miR-138 silence, qRT-PCR was showed valid for inhibitor miR-138. And Western blot, CASY(r)-technology was put in use to study some change of mouse mammary epithelial cells after miR138 inhibitor. It was shown that miR-138 suppresses the exepress of PRL-R(P
