Lentivirus-mediated silencing of spindle and kinetochore-associated protein 1 inhibits the proliferation and invasion of neuronal glioblastoma cells.

Spindle and kinetochore‑associated protein 1 (SKA1) is an important component of the human kinetochore, which plays a key role in mitosis. The resent study was designed to investigate the role of SKA1 in human glioblastoma. The results of the present study demonstrated that SKA1 was expressed in human glioblastoma cells. In addition, the knockdown of SKA1 expression in the A172 and U251 human glioblastoma cell lines was accomplished using a lentivirus infection method. An MTT assay demonstrated that downregulation of SKA1 may inhibit cell proliferation, without affecting the cell cycle. Furthermore, knockdown of SKA1 expression resulted in reduced cell invasion. The results of the present study indicated that SKA1 may be a potential target protein for antiproliferative and anti‑invasive therapeutic strategies of human glioblastoma.
