doi: 10.3892/or.2020.7506
Figure Lengend Snippet: miR-25-3p is a direct target of LINC00858. (A) Potential binding region between miR-25-3p and LINC00858 was predicted using StarBase V2.0 database. (B) miR-25-3p was validated as a direct target of LINC00858 using dual luciferase reporter assays in (B) SW48 and (C) RKO cells. (D) RIP assay confirmed the interaction between miR-25-3p and LINC00858. (E) The expression levels of miR-25-3p in CRC tissues (n=60) compared with that in adjacent normal tissues (n=60) were assessed using qPCR. (F) Correlation between LINC00858 and miR-25-3p expression levels was analyzed using Pearson's correlation analysis. (G) The expression levels of miR-25-3p in TP53-WT CRC cell lines (RKO, HCT116, Colo-678, LoVo, SW48 and LS174T) and human normal colonic fibroblast (CCD-112CoN) were assessed using qPCR. (H and I) The expression levels of miR-25-3p in (H) SW48 and (I) RKO cells transfected with LINC00858 shRNAs. Data are presented as the mean ± SEM; n≥3. *P<0.05; **P<0.01. CRC, colorectal cancer; miR, microRNA; q, quantitative; WT, wild-type; sh, short hairpin; MUT, mutant; AGO2, protein argonaute-2.
