WebOct 1, 2024 · Author summary In a transformation model based on the cancer-causing Epstein-Barr virus (EBV), we previously demonstrated that the cellular oncoprotein STAT3, activated during transformation, impairs ATR's ability to phosphorylate Chk1 in response to replication stress, thereby relaxing the intra-S phase checkpoint. WebSpecifically, STAT3 interrupts ATR-to-Chk1 signaling by promoting loss of Claspin via caspase 7. These findings not only demonstrate how EBV exploits host STAT3 to interrupt DDR-signaling and drive cell proliferation past the S phase, but also reveal a function for STAT3 in regu- WebJak1/Stat3 activation led to very high intact FGF23 levels in the plasma and lower PTH and total iron levels and higher calcitriol levels in female Jak1 S645P+/− mice (Fig. 1C‒F). … ccs lyreco
