Long Noncoding RNA XIST Regulates miR-137-EZH2 Axis to Promote Tumor Metastasis in Colorectal Cancer.

ABSTRACT: We aimed to investigate the significant role of long noncoding RNA X inactive specific transcript (XIST) in regulating tumor metastasis in colorectal cancer (CRC), as well as its possible mechanism. Expression of lncRNA XIST in CRC tissues and CRC cells was detected. CRC cells were transfected with pc-XIST, blank control si-XIST, or si-control, and then the effects of lncRNA XIST on CRC cell migration and invasion were investigated, along with the interaction between lncRNA XIST and miR-137. lncRNA XIST was upregulated in CRC tissues. Compared with HT29 cells that had low metastatic potential, XIST was markedly more highly expressed in LoVo cells that had a higher metastatic potential. Overexpression of XIST promoted the migratory and invasive potential of HT29 cells, while knockdown of XI
