Lnc-LRRTM4 promotes proliferation, metastasis and EMT of colorectal cancer through activating LRRTM4 transcription

Abstract

Abstract Numerous mechanisms have shown that long noncoding RNAs (lncRNAs) promote the development of colorectal cancer (CRC), but the role of lnc-LRRTM4 in the progression of CRC remains unclear. In this article, we found that lnc-LRRTM4 was highly expressed in CRC tissues and cell lines and that lnc-LRRTM4 could promote the proliferation and metastasis of CRC cells. These consequences were achieved by lnc-LRRTM4 directly binding to the promoter of LRRTM4 to induce its transcription. Moreover, lnc-LRRTM4 enhanced the growth of CRC cells in vivo by promoting cell cycle progression and reducing apoptosis. Taken together, our results revealed that lnc-LRRTM4 promotes the proliferation and metastasis of CRC cells, suggesting that it may be a potential diagnostic and therapeutic target for CRC.
