Abstract

MicroRNA (miR)‑106b‑5p has been reported to act as both an oncogene and tumor suppressor in several tumors. The aim of the present study was to investigate the biological function of miR‑106b‑5p in osteosarcoma (OS). miR‑106b‑5p expression was observed to be significantly increased in OS tissues and cell lines. MTT assay and flow cytometry analysis determined that miR‑106b‑5p inhibitor transfection suppressed OS cell proliferation and induced cell cycle G0/G1 phase arrest. Furthermore, bioinformatics analysis and a luciferase reporter assay demonstrated that cyclin‑dependent kinase inhibitor 1A (CDKN1A) was a potential target of miR‑106b‑5p. p21 protein expression was found to be significantly increased by miR‑106b‑5p downregulation in OS cells. Further analysis demonstrated that CDKN1A was downregulated in OS tissues and was negatively correlated with miR‑106b‑5p expression. Furthermore, upregulation of CDKN1A expression mimicked, whilst CDKN1A knockdown reversed the suppressive effects of miR‑106b‑5p inhibitor on OS cell proliferation and cell cycle progression. In summary, the present data suggested that miR‑106b‑5p promotes cell proliferation and cell cycle progression by directly targeting CDKN1A in OS.
