Decreased expression of miRNAs of the miR-200 family has been implicated in the growth and metastasis of breast cancer cells. Of this family, miR-200c has garnered particular attention as a consequence of its ability to target ZEB1 and ZEB2, mediators of epithelial- mesenchymal transition. An article in the previous issue of Breast Cancer Research identifies additional targets of miR-200c that link increased cancer cell invasiveness, resistance to apoptosis, and induction of breast cancer stem cell characteristics.
miR-200 家族的 miRNA 表达降低与乳腺癌细胞的生长和转移有关。在这个家族中,miR-200c 因其能够靶向上皮-间充质转化的调节因子 ZEB1 和 ZEB2 而备受关注。上一期的《乳腺癌研究》杂志上的一篇文章确定了 miR-200c 的其他靶标,这些靶标与增加癌细胞侵袭性、抗细胞凋亡以及诱导乳腺癌干细胞特性有关。
