1 Upregulated cyclin B1/CDK1 mediates apoptosis following 2-methoxyestradiol-induced mitotic catastrophe: Role of Bcl-XL phosphorylation. 2-Methoxyestradiol cyclin dependent kinase 1 Homo sapiens
2 Earlier we showed that 2-methoxyestradiol increases the level and activity of cyclin B1/CDK1, which subsequently induces mitotic prometaphase arrest. 2-Methoxyestradiol cyclin dependent kinase 1 Homo sapiens
3 In the present study, we demonstrate that upregulation of cyclin B1/CDK1 is responsible for the increased phosphorylation of the anti-apoptotic proteins Bcl-2 and Bcl-XL in 2-methoxyestradiol-induced, mitotically-arrested cancer cells. 2-Methoxyestradiol cyclin dependent kinase 1 Homo sapiens
4 Together, these results indicate that cyclin B1/CDK1 upregulation in cancer cells undergoing 2-methoxyestradiol-induced mitotic catastrophe causes apoptosis via Bcl-XL phosphorylation. 2-Methoxyestradiol cyclin dependent kinase 1 Homo sapiens
