Abstract

Colorectal cancer (CRC) is a burdensome health concern worldwide. Long non-coding RNA (lncRNA) have emerged as vital roles in multiple cancers, including CRC. Increasing evidence has demonstrated that lncRNA CCDC144NL-AS1 acts crucial roles in tumor developments. Nevertheless, its role in CRC remains largely unknown. The level of CCDC144NL-AS1 expression was detected in 100 CRC tissues and paired adjacent tissues. The gain- and loss-of-function experiments were conducted to investigate the biological functions of CCDC144NL-AS1 and . The potential mechanism of CCDC144NL-AS1 exerting as competing endogenous RNAs (ceRNAs) was demonstrated by bioinformatics, luciferase reporter assay and experiments. CCDC144NL-AS1 was up-regulated in CRC tissues and cells. High CCDC144NL-AS1 was connected with the adverse clinicopathological features and worse prognosis of CRC. Furthermore, knockdown of CCDC144NL-AS inhibited the cell proliferation and led to the cell cycle G0-1/S arrest, whereas upregulated CCDC144NL-AS1 obtained the inverse results. Further study found that CCDC144NL-AS1 functioned as ceRNAs in regulating CRC proliferation. MiR-363-3p was the target of CCDC144NL-AS1, which sponges GALNT7 in regulating cell growth of CRC. The study demonstrated that the CCDC144NL-AS1/miR-363-3p/GALNT7 axis exerts on key roles in cell proliferation and presents an emerging target for CRC therapy and prognostic biomarker.
