Web1 jul. 2010 · Here, we surprisingly show that PARP1 is hyperactivated in replicating BRCA2-defective cells. PARP1 hyperactivation is explained by the defect in HR as shRNA depletion of RAD54, RAD52, BLM, WRN, and XRCC3 proteins, which we here show are all essential for efficient HR and also caused PARP hyperactivation and correlated with an … WebThe data show that cells defective in HR (Xrcc2 and Brca2 mutants) are extremely sensitive to cell death by apoptosis and chromo- somal aberration formation and less …
