WebMay 4, 2024 · Here, we show that constitutive CHK1 expression in GBM activates a recursive pSTAT3-CIP2A oncogenic circuit that drives tumor growth. Inhibition of this circuit retards GBM growth in heterotopic and orthotopic transplants and prolongs survival. Materials and Methods Cell lines and culture WebMar 17, 2014 · We find that STAT3 interrupts ATR-to-Chk1 signaling by promoting loss of Claspin, a protein that assists ATR to phosphorylate Chk1. This loss of Claspin which ultimately facilitates cell proliferation is mediated by caspase 7, a protein that typically promotes cell death. fnaf world how to get auto mimic https://pcdotgaming.com
