A novel lncRNA LOC101927746 accelerates progression of colorectal cancer via inhibiting miR-584-3p and activating SSRP1
An increasing number of reports have indicated that long noncoding RNAs (lncRNAs) are involved in the pathogenesis of colorectal cancer (CRC). However, many lncRNAs remain unidentified in CRC, and their functions are yet to be elucidated. In this study, we investigated the function of lncRNA LOC101927746 in CRC progression. We found that LOC101927746 expression was significantly increased in CRC tissues according to the GEO dataset. Moreover, LOC101927746 expression was positively correlated with tumor stage and metastasis. Additionally, the high expression of LOC101927746 predicted poor prognosis in CRC patients. Functionally, we demonstrated that LOC101927746 silencing significantly suppressed the proliferation, migration, and invasion of CRC cells. In terms of its mechanism, LOC101927746 could serve as a competing endogenous RNA to inhibit miR-584-3p and activate its target gene SSRP1. The expression of miR-584-3p was inversely correlated with either LOC101927746 or SSRP1 in CRC tissues. The over expression of SSRP1 or inhibition of miR-584-3p could reverse the effects of LOC101927746 knockdown in CRC cells. Taken together, our results suggest that the LOC101927746/miR-584-3p/SSRP1 axis modulates CRC progression. (C) 2019 Elsevier Inc. All rights reserved.
