Spindle and kinetochore-associated protein 1 (SKA1), a component of microtubule-binding complex of kinetochore, is essential for proper chromosome segregation. Recently, SKA1 has been shown to be involved in malignant progression of several human cancers. However, its role in bladder cancer is still unknown. To evaluate the function of SKA1 in bladder cancer cells, the authors employed an RNA interference lentivirus system to deplete its expression in both BT5637 and T-24 bladder cancer cells. The cell proliferation was significantly decreased in both cell lines after SKA1 knockdown. Moreover, the colony formation capacity was impaired by SKA1 silencing. Flow cytometry analysis showed that depletion of SKA1 led to cell cycle arrest at S phase. Furthermore, knockdown of SKA1 in T-24 cells obviously downregulated the expressions of CDK4 and Cyclin D1, and alleviated the activations of ERK2 and AKT, conducive to cell growth inhibition. These findings suggested that knockdown of SKA1 could potently suppress bladder cancer cell proliferation in vitro and lentivirus-mediated silencing of SKA1 might serve as a novel strategy for gene therapy of bladder cancer.

Spindle and kinetochore-associated protein 1 is a microtubule-binding subcomplex of the outer kinetochore that is essential for proper chromosome segregation. Recently, spindle and kinetochore-associated protein 1 has been highlighted as a biomarker in various cancers; however, the precise role of spindle and kinetochore-associated protein 1 in prostate cancer remains unknown. This study aims to evaluate whether spindle and kinetochore-associated protein 1 affects the biological behaviors of prostate cancer. We investigated the expression of spindle and kinetochore-associated protein 1 in a series of prostate cancer tissues as well as in a panel of prostate cancer cell lines. Cell proliferation, migration, and invasion were evaluated in spindle and kinetochore-associated protein 1 knockdown prostate cancer cell lines by MTT and Transwell assays. Our results showed that the expression of spindle and kinetochore-associated protein 1 was remarkably upregulated in prostate cancer at both messenger RNA and protein levels compared with non-cancerous tissue. Knockdown of spindle and kinetochore-associated protein 1 repressed the ability of cell proliferation, migration, and invasion of prostate cancer cells. Moreover, inhibition of spindle and kinetochore-associated protein 1 could inhibit the activity of AKT and ERK pathway. In conclusion, our findings suggest that spindle and kinetochore-associated protein 1 could serve as a potential therapeutic target in prostate cancer patients.
