  • Title: LINC01123 Promotes the Progression of Colorectal Cancer via miR-625-5p/LASP1 Axis.
    Author: Shang T, Zhou X, Chen W.
    Journal: Cancer Biother Radiopharm; 2021 Nov; 36(9):765-773. PubMed ID: 32423238.
    Abstract:
    Background: Evidence from previous investigations points to a rising trend in the incidence of colorectal cancer (CRC) worldwide. The mortality resulting from this cancer is high. Unlike nonsmall cell lung cancer for which LINC01123 has been investigated, there are few reports on how this long noncoding RNA (lncRNA) regulates CRC. Materials and Methods: The authors evaluated the expression of LINC01123 in CRC tissues by quantitative real-time polymerase chain reaction. Its impact on cancer cell behavior was analyzed with cell counting kit-8 (CCK-8), colony formation, and Transwell invasion assays. To establish the mechanisms of LINC01123 in CRC they carried out RIP and luciferase reporter assays. Results: The results show that LINC01123 expression is abnormally elevated in CRC tissues and cell lines. High LINC01123 expression closely correlates with poor prognosis, advanced TNM stage, and lymph-node metastasis. The authors also show that knockdown of LINC01123 inhibits proliferation and invasion in CRC cells. In mechanism, it is revealed that LINC01123 may function as competitive endogenous RNA (ceRNA) against miR-625-5p to promote LIM and SH3 protein 1 (LASP1) expression. Conclusions: The data indicate that high LINC01123 exerts its oncogenic roles by regulating the miR-625-5p/LASP1 axis in CRC progression.
