Aim: Homeobox (HOX) genes and their protein products have been found to function as oncogenes in the progression of many cancers. But the role of Homeobox C10 (HOXC10) in osteosarcoma (OS) still remains less understood. In this study, we firstly determine the biologic functions of HOXC10 in OS.
Materials and methods: We examined the expression of HOXC10 in OS tissues by quantitative real-time polymerase chain reaction and Western blot assays. We investigated the effects of HOXC10 on cell proliferation, apoptosis and caspase 3 activity in three OS cell lines by RNA interference, Cell Counting Kit-8, flow cytometry and colorimetric assays.
Results: We found that HOXC10 was elevated in OS tissues. Silencing HOXC10 significantly inhibited cell proliferation, induced cell apoptosis and increased the expression and activity of caspase 3. The resistance assay further suggested that HOXC10 affected cell growth and apoptosis through regulating the expression and activity of caspase 3.
Conclusion: HOXC10 might function as an oncogene in OS by regulating the expression and activity of caspase 3.
