(B) Upper -panel: MCF-7 cells transfected with Rac1 siRNA (Rac1) or control siRNA (Control) were incubated for the indicated moments and analyzed for protein degrees of Rac1 and Actin. in inhibition of Cdc2 kinase and following G2/M cell-cycle arrest. Prior research from our lab showed the fact that G2/M checkpoint activation after IR publicity of…
