Abstract

Dysregulation of long non‑coding RNAs (lncRNAs) is involved in the development of colorectal cancer (CRC). In the present study, the identification of muscle blind like splicing regulator 1 antisense RNA 1 (MBNL1‑AS1) lncRNA was reported. Firstly, Cell Counting Kit‑8, EdU and colony formation assays were uesed to explore the role of MBNL1‑AS1 in regulating the proliferation of CRC cells. According to TCGA database, it was found that MBNL1‑AS1 was correlated with microRNA (miR)‑29c‑3p and blood vessel epicardial substance (BVES) expression in CRC cells. Then, the regulation among MBNL1‑AS1, miR‑29C‑3P and BVES was detected by dual luciferase reporter assay and the function of MBNL1‑AS1/miR‑29C‑3P/BVES axis was explored by rescue assay. The results demonstrated that MBNL1‑AS1 expression was decreased in CRC and was associated with the size of tumors derived from patients with CRC. Functionally, the upregulation of MBNL1‑AS1 suppressed CRC cell proliferation in vitro and inhibited tumor growth in vivo, while knockdown of MBNL1‑AS1 expression caused the opposite effects. MBNL1‑AS1 expression correlated with BVES expression in CRC tissues and MBNL1‑AS1 enhanced the stability of BVES mRNA by functioning as a competing endogenous RNA to sponge miR‑29c‑3p; the latter directly targeted MBNL1‑AS1 and BVES mRNA 3'UTR. Collectively, the results indicated that MBNL1‑AS1 suppressed CRC cell proliferation by regulating miR‑29c‑3p/BVES signaling, suggesting that the MBNL1‑AS1/miR‑29c‑3p/BVES axis may be a potential therapeutic target for CRC.
