Abstract
Osteosarcoma (OS) is the most commonly diagnosed primary malignancy affecting the bone. UbcH10 is a cancer-related E2-ubiquitin-conjugating enzyme. An overexpression of UbcH10 is significantly associated with tumor grade and cellular proliferation. However, limited evidence exists with regard to the biological function of UbcH10 in OS. The present study created a UbcH10 knockdown OS cell line using lentivirus-mediated RNA interference. The expression of UbcH10 was significantly reduced in UbcH10-targeted small hairpin RNA-expressing lentivirus OS cells. The downregulation of UbcH10 suppressed OS cell proliferation and colony formation ability via decreased Ki-67 expression. UbcH10 knockdown OS cells exhibited impaired invasion and migration abilities. Furthermore, knockdown of UbcH10 led to decreased levels of matrix metalloproteinase-3 and -9 in OS cells. The present study demonstrated the role of UbcH10 in OS cell proliferation, invasion and migration, which suggests that UbcH10 may be a potential candidate for OS therapy.
