The role of PARP1 in the DNA damage response sparked interest in the development of PARP inhibitors as potential chemosensitizers for the treatment of cancer ( 1 , 2 ).
WebIt appears that the activity of BER, MMR, and HR can affect the toxicity of alkylating agents, radiation, and topoisomerase I poisons in combination with PARP1 inhibitors; p53 status does not seem to affect the efficacy of PARP1 inhibition [126]. Several trials are now ongoing in order to determine whether PARP1 inhibitors can sensitize tumors to different … Web9 Sep 2024 · PARP1 is vital for the repair of single-strand breaks (Fisher et al., 2007; Hanzlikova et al., 2016). Since single-strand breaks are also produced as an intermediate of Base-Excision Repair (BER); PARP is also sometimes considered to be required for BER, as suggested by several studies (Dantzer et al., 1999, 2000).
