Advances in study of miR-106b-25 cluster in cancer / 国际肿瘤学杂志

ABSTRACT

miR-106b-25 cluster is composed of miR-106b,miR-93 and miR-25,and is a paralogue of miR-17-92 cluster.Some studies have shown that the members in miR-106b-25 cluster abundantly expressed in many cancers.Over-expressions of these miRNAs promote the growth of tumor cells by negatively regulating p21 and p57,and suppress the apoptosis of tumor cells through inhibition of Bim.Moreover,high expression of miR-106b-25 cluster might endue tumor cells with resistance to inhibitory effect of cell growth induced by TGF-β signaling.
