WebAug 31, 2024 · A3A expression caused ATR-dependent phosphorylation of Chk1 and cell-cycle arrest, consistent with replication checkpoint activation. Further, replication checkpoint blockade via small-molecule inhibition of ATR kinase in cells expressing A3A led to apoptosis and cell death. WebMay 16, 2024 · In addition, CHK1 autophosphorylation (S296), a marker of CHK1 kinase activity, was increased in isolated PAH-PASMCs ( Figure 1A ). To further demonstrate that PAH-PASMCs experience endogenous DNA damage/RS, phosphorylation levels of H2AX and RPA32, 2 markers of DNA damage and RS, 24 were measured.
