The checkpoint kinase 1 chk1 arrest
網頁2016年9月27日 · Targeting the cell cycle checkpoints in cancer. a Chk1/2 or ATR inhibitors in combination with DNA damaging drugs forces cancer cells with DNA damage to … 網頁The mechanism controlling G 2 /M checkpoint activation after DNA damage was thought to be mediated primarily by nuclear Chk1/Chk2 kinases. Recent evidence indicates that this checkpoint is more complex, involving at least two different biochemical systems that target the Cdc25B and Cdc25C phosphatases .
