WebJun 2, 2024 · In addition to PARP, targeting other DDR proteins, particularly DDR kinases such as ATM, ATR, CHK1/2, DNA-PK, or WEE1, represents an attractive therapeutic strategy in a variety of tumor contexts. ATR is a DDR kinase that is activated by DNA damage or DNA replication stress and has an important role in preventing excessive … WebApr 6, 2024 · The ATR-Chk1 signaling is prevented from activation. The stalled replication fork may collapse and trigger p53-dependent apoptosis, ultimately leading to defective liver regeneration.
WebTo confirm that the ATM/ATR-CHK1 signaling pathway is functionally downregulated in the E4F1-depleted cells, we next exposed the control or E4F1-shRNA-transduced cells to the DNA damaging agents, Cisplatin or Gemcitabine, and then monitored the phosphorylation levels of γH2AX and CHK1 in these cells, two well-established biomarkers of the ATM ... WebApr 24, 2024 · Background The ataxia telangiectasia and Rad3-related (ATR) checkpoint kinase 1 (CHK1) pathway plays an essential role in suppressing replication stress from DNA damage and oncogene activation.
