WebCheckpoint kinase 1, commonly referred to as Chk1, is a serine/threonine-specific protein kinase that, in humans, ... WEE1 kinase and PLK1 are also targeted by Chk1 to induce cell cycle arrest. Phosphorylation of WEE1 … WebNumerous, promising preclinical and clinical studies suggest that ATM, ATR, CHK1, CHK2 and WEE1 inhibitors or modulators, alone or in combination with other therapeutics, could be potent therapeutic options for certain cancers, including TNBC [24,25,26,27,28]. Understanding the molecular and cellular regulatory mechanisms of the ATM/ATR-CHK1 ...

WebApr 29, 2009 · To achieve this, Chk1 phosphorylates Wee1, stabilizing the protein to increase cellular pools of Wee1 , and also Cdc25, where phosphorylation is inhibitory over catalytic activity and also affects sub-cellular localization [13, 14]. Cells that lack both Wee1 and Cdc25 are viable, and still utilize the regulated abundance of cyclins to control ... WebFeb 27, 2015 · While Chk1, Wee1, and ATR are widely known as key regulators of the G2 checkpoint, these kinases also regulate CDK activity during S phase, and thereby prevent the induction of DNA damage during normal S phase progression (Syljuåsen et al., 2005; Sørensen and Syljuåsen, 2012). how does cml develop

WebJan 1, 2013 · Indeed, siRNA-mediated depletion of Wee1 significantly impairs cell viability, and the majority of neuroblastoma cells demonstrate single-agent sensitivity to Wee1 or Chk1 inhibition, with IC 50 s in physiologically attainable ranges (Figure 2). Consequently, sustained inhibition of Chk1 or Wee1 results in apoptosis as evidenced by PARP ... WebCHK1, WEE1 and NEK11 siRNA were sensitizing hits at 250 and 750 nM MK1775.
