Abstract
- Objectives Micro RNAs (mi RNAs) contribute to control of cell cycle progression and are frequently deregulated in cancer. The focus of this study was to determine effects of miR-142-3p on the cell cycle progression and cancer cell proliferation. Materials and methods RT- qPCR was performed to determine expression of miR-142-3p in a range of cancer cell lines and in clinical cancer specimens. To further understand its role, we restored its expression in cancer cell lines by transfection with miR-142-3p mimics or inhibitors. Effects of miR-142-3p on cell cycle progression and cell proliferation were also determined. Results miR-142-3p was down-regulated in both cancer cell lines and cancer specimens. Its overexpression suppressed proliferation, whereas its depletion promoted it. In addition, miR-142-3p lead to cell cycle arrest in G2/M. Moreover, CDC25C was identified as being a target of miR-142-3p, ectopic expression of which reversed suppression of cell proliferation. Conclusions Our observations suggest that miR-142-3p functioned as a tumor suppressor by targeting CDC25C. [ABSTRACT FROM AUTHOR]
