Mechanism of parp inhibitor resistance
WebThe next generation PARP inhibitor AZD2461, which has poor PgP affinity, may prove to overcome this mechanism of resistance [17]. 8. PARG mutations can lead to PARP resistance via a mechanism that doesn’t restore HRR. Loss of PARG results in PAR chains not being degraded, so PARP activity has a bigger manifestation than it otherwise would … WebMar 1, 2024 · Most clinically relevant PARP-inhibitors work by binding to activated PARP1 molecules and trapping them onto damaged DNA [57] leading to stalling of the replication fork and the accumulation of single-stranded DNA breaks (SSBs). PARP inhibition also deregulates fork speed [58] and stability.
