Product Description
Anticancer agent. Inhibits carcinogenesis at the initiation stage but has been shown to enhance tumor incidence at a post-initiation stage. Inhibits the expression of cyclin-dependent kinase 6 (CDK6) and induces G1 cell cycle arrest independent of estrogen receptor signalling. Causes a dose-dependent increase in E-cadherin and BRCA1 expression.
