WebFeb 19, 2024 · Sustained CHK2 activity, but not ATM activity, is critical to maintain a G1 arrest after DNA damage in untransformed cells. Our data indicate that G1 checkpoint maintenance relies on CHK2 and that its negative regulation is crucial for G1 checkpoint recovery after DSB induction. WebJul 6, 2010 · The present in vitro and in vivo studies together show that I3C-induced activation of the ATM-Chk2 pathway and degradation of Cdc25A represent a novel molecular mechanism of I3C in arresting the G 1 cell cycle and inhibiting the growth of breast cancer cells.
WebHere, we show that Chk2 is negatively correlated with VM formation in p53-mutated TNBC. Its activation by DNA-damaging agents such as cisplatin, etoposide, and DPT reduces VM formation. Mechanistically, the Chk2-PKM2 axis plays an important role in the inhibition of VM formation at the level of metabolic regulation.
