WebSynthetic lethality: definition and approaches for the identification of synthetic lethal interactions. A) Synthetic lethality is defined by cellular or organismal lethality caused by combined alterations of gene pairs that are otherwise individually viable. A commonly employed and therapeutically relevant definition encompasses pharmacologic inhibition … WebNov 15, 2013 · The proof of principle that the synthetic lethality concept is clinically translatable is the efficacy of drugs that target the single-strand DNA repair enzyme poly (ADP-ribose) polymerase (PARP) in tumors with mutations in the BRCA1 and BRCA2 genes ( 7 ). These genes encode tumor suppressor proteins that help repair damaged DNA.
