摘要
Introduction: Increasing evidence has shown that abnormally expressed long non-coding RNA (lncRNA) plays crucial roles in prostate cancer (PCa) progression. Materials and Methods: Here, we analyzed the expression level of lncRNA HAND2 antisense RNA 1 (HAND2-AS1) in PCa cells and tissues. Function assays were performed to investigate the biological roles of HAND2-AS1 in PCa cell behaviors. Bioinformatics methods, luciferase activity reporter assay, and RNA pull-down assay were performed to validate the connection of microRNA-106a-5p (miR-106a-5p) with HAND2-AS1. Also, the target of miR-106a-5p was explored using the same methods. Results: Our results revealed HAND2-AS1 expression was decreased in both PCa cells and tissues. In vitro functional assays showed HAND2-AS1 could inhibit PCa cell proliferation and colony formation through promoting cell apoptosis. Dual-luciferase activity assays showed miR-106a-5p could directly bind with HAND2-AS1 and RNA binding motif protein 24 (RBM24). Mechanistically, we showed that HAND2-AS1 regulates PCa cell behaviors via targeting miR-106a-5p/RBM24 axis. Conclusion: In summary, our results illustrated that HAND2-AS1 functions as miR-106a-5p sponge to regulate RBM24 expression, and to influence PCa progression.
