Abstract
In this study, we investigated the role of LINC00520 in colorectal cancer (CRC) progression. We analyzed LINC00520 expression in 15 pairs of CRC tissues and adjacent tissues using qRT-PCR, revealing significantly elevated levels in CRC tissues and cell lines. Lentivirus-mediated up/down-regulation of LINC00520 in CRC cell lines demonstrated that increased LINC00520 expression enhanced cell invasiveness, as confirmed by transwell and wound healing assays. Bioinformatics analysis identified a regulatory axis involving LINC00520, microRNA-195-3p, and NAT2. Luciferase assays confirmed direct binding between LINC00520 and microRNA-195-3p, as well as microRNA-195-3p and NAT2. Overexpression of NAT2 reversed the inhibitory effects on invasion and migration induced by LINC00520 silencing. This suggests that LINC00520, highly expressed in CRC tissues, may modulate tumor biological functions through the microRNA-195-3p/NAT2 axis. Our findings provide insights into the mechanism underlying CRC progression, highlighting the potential of LINC00520 as a therapeutic target.
