摘要
Recently, miR-485-5p was identified as a tumor-suppressing microRNA in some human cancers. However, the expression and biological role of miR-485-5p in colorectal cancer (CRC) remain unclear. Herein, we found that the expression of miR-485-5p in CRC tissues and cell lines was much lower than that in the control, respectively. Moreover, the overexpression of miR-485-5p could inhibit the proliferation and invasion of CRC cell lines in vitro and in vivo. Furthermore, we determined that miR-485-5p could decrease the expression of CD147 by directly targeting CD147 3UTR. In addition, the expression of CD147 was inversely correlated with the expression of miR-485-5p in CRC tissues. Collectively, our results revealed that miR-485-5p played a pivotal tumor-suppressing role in CRC through downregulation of cancer-associated gene CD147, and may provide a better understanding of the pathogenesis in CRC and a new bio-target for CRC therapy.
