Abstract
- Cdc kinase subunit 1 (Cks1) has been shown to involve in the regulation of cell cycle progression and p27 Kip1 degradation. To define the role of Cks1 in lung tumorigenesis, we examined the expression of Cks1 in human lung cancer cell lines and tested the effect of Cks1-specific small interfering RNA (siRNA) on these cells. Reverse transcriptase-polymerase chain reaction (RT-PCR) and western blot analysis showed that Cks1 was highly expressed in human lung cancer cells. Transfection of Cks1 siRNA down-regulated Cdc2 kinase activity and induced G2/M arrest in Cks1- overexpressing H358 lung cancer cells. Long-term treatment of Cks1 siRNA induced caspase activation and apoptosis in H358 cells . On the contrary, Cks1 siRNA did not affect viability of normal human lung fibroblasts under the same experimental condition. Collectively, our results suggest that Cks1 participates in the steps of lung tumorigenesis and this gene may be a target for the treatment of lung cancer.
