Abstract

The alteration of microRNA (miR)‑130b expression has been associated with promoting or suppressing numerous types of human cancer. A previous study evaluated the expression level of miR‑130b in osteosarcoma tissues, and subsequently investigated the effects of miR‑130b on the regulation of osteosarcoma cells malignant behavior in vitro. The study revealed that miR‑130b expression levels were significantly reduced in osteosarcoma tissues and cell lines, compared with in adjacent tissues or normal cell lines. The expression of miR‑130b inhibited the proliferation of osteosarcoma U‑2OS and Saos‑2 cells and impaired their ability to migrate, invade and form colonies. Furthermore, analysis using TargetScan and a dual‑luciferase reporter assay demonstrated that miR‑130b directly interacted with the 3'‑untranslated region of transforming growth factor α (TGFA) and suppressed TGFA expression. TGFA and miR‑130b were also inversely expressed in osteosarcoma tissues. In addition, expression of TGFA was able to alter miR‑130‑regulated osteosarcoma cell proliferation, migration and invasion. Thus, the present study demonstrated that miR‑130b was downregulated in osteosarcoma tissues and cell lines, whereas the expression of miR‑130b suppressed osteosarcoma cell malignant behavior. At the gene level, miR‑130 directly targets and inhibits TGFA expression, in addition to phosphorylated protein kinase B and epidermal growth factor receptor expression levels. Further study is required to evaluate miR‑130b antitumor activity in osteosarcoma.
