1 The role of p27(Kip1) in dasatinib-enhanced paclitaxel cytotoxicity in human ovarian cancer cells. Paclitaxel cyclin dependent kinase inhibitor 1B Homo sapiens
2 The siRNA knockdown of p27(Kip1) decreased dasatinib- and paclitaxel-induced apoptosis compared with a negative control siRNA (sub-G1 fraction, control siRNA vs. p27(Kip1) siRNA: 42.5% vs. 20.1%, difference = 22.4%, 95% CI = 20.1% to 24.7%, P = .017). Paclitaxel cyclin dependent kinase inhibitor 1B Homo sapiens
3 Studies with forced expression and siRNA knockdown of Bcl-2 and Cdk1 suggest that dasatinib-mediated induction of p27(Kip1) enhanced paclitaxel-induced apoptosis by negatively regulating Bcl-2 and Cdk1 expression. Paclitaxel cyclin dependent kinase inhibitor 1B Homo sapiens
4 CONCLUSION: Inhibition of Src family and Abl kinases with either siRNAs or dasatinib enhances paclitaxel sensitivity of ovarian cancer cells through p27(Kip1)-mediated suppression of Bcl-2 and Cdk1 expression. Paclitaxel cyclin dependent kinase inhibitor 1B Homo sapiens
