ABSTRACT
Oral squamous cell carcinoma (OSCC) is the most common type of oral cancer, with a poor prognosis, yet the underlying mechanism needs further exploration. Non-SMC condensin I complex subunit D2 (NCAPD2) is a widely expressed protein in OSCC, but its role in tumor development is unclear. This study aimed to explore NCAPD2 expression and its biological function in OSCC. NCAPD2 expression in OSCC cell lines and tissue specimens was analyzed using quantitative polymerase chain reaction, western blotting, and immunohistochemistry. Cancer cell growth was evaluated using cell proliferation, 5-Ethynyl-2'-deoxyuridine (EdU) staining, and colony formation assays. Cell migration was evaluated using wound healing and Transwell assays. Apoptosis was detected using flow cytometry. The influence of NCAPD2 on tumor growth in vivo was evaluated in a mouse xenograft model. NCAPD2 expression was significantly higher in OSCC than that in normal oral tissue. In vitro, the knockdown of NCAPD2 inhibited OSCC cell proliferation and promoted apoptosis. NCAPD2 depletion also significantly inhibited the migration of OSCC cells. Moreover, NCAPD2 overexpression induced inverse effects on OSCC cell phenotypes. In vivo, we demonstrated that downregulating NCAPD2 could inhibit the tumorigenicity of OSCC cells. Mechanically, OSCC regulation by NCAPD2 involved the Wnt/ß-catenin signaling pathway. These results suggest NCAPD2 as a novel oncogene with an important role in OSCC development and a candidate therapeutic target for OSCC.
