CDR1as/miR-7-5p/IGF1R axis contributes to the suppression of cell viability in prostate cancer

Objectives: Prostate cancer is the most frequently diagnosed male cancer and the fifth highest cause of cancer mortality in men. CDR1as has played an essential role in the growth of several malignancies. However, its significance in the progression of prostate cancer has not been investigated. We aimed to investigate the role and mechanism of CDR1as in the development of prostate cancer and identify a new target for diagnostics and treatment. Methods: CDR1as siRNA and miR-7-5p mimic were transfected into PC3 and DU145 PCa cell lines and their effects on cellular processes were investigated. Cell viability was measured by WST-8 assay. The role of CDR1as and/or miR-7-5p on PCa cell migration was detected using the scratch-wound assay. The apoptotic capacity of the cells was evaluated using the Caspase-3 kit. The potential targets of miR-7-5p were defined via in silico tools. mRNA and protein expression levels of IGF1R and EIF4E were detected by qRT-PCR and western blot assays, respectively. The matching between miR-7-5p and IGF1R was defined via luciferase reporter assay. Results: Inhibiting CDR1as or restoring miR-7-5p reduced prostate cancer cell proliferation and migration while increasing apoptosis. Silencing CDR1as elevated the expression of miR-7-5p while decreasing IGF1R. Conclusions: CDR1as functions as a miR-7-5p sponge, increasing IGF1R expression and promoting tumor development.
