Abstract

Dysregulated microRNA (miRNA) expression is involved in the occurrence and development of colorectal cancer (CRC) through the regulation of various important physiological events. Hence, miRNAs may be used as effective targets for CRC treatment; however, this hypothesis warrants further investigation. miRNA-511 (miR-511) plays vital roles in the progression of different tumor types. However, the expression, exact role, and the mechanisms underlying the regulation of colorectal carcinogenesis and progression by miR-511 remain poorly understood. This study presents that miR-511 expression was decreased in CRC tissues and cell lines compared with that in adjacent nonneoplastic tissues and normal human colon epithelium cell lines, respectively. The enforced expression of miR-511 in CRC cells significantly reduced cell proliferation and invasion. Hepatoma-derived growth factor (HDGF) was mechanically validated as a direct target of miR-511 in CRC. Furthermore, miR-511 was negatively associated with HDGF in CRC tissues. The restored HDGF expression can abrogate the tumor-suppressive roles of miR-511 in CRC cells. More importantly, miR-511 overexpression suppressed the PI3K/AKT signaling pathway in CRC. These results suggest that miR-511 can potentially serve as a therapeutic target for the therapy of patients with CRC.
