WebMay 24, 2024 · Synthetic lethality is the technique of finding pairs of genes that cause cell death when simultaneously inactivated. The first synthetic lethal pairing discovered involved the well-known BRCA1/BRCA2 genes. When the DNA repair activity of either of the BRCA genes is impaired, cells become dependent on the parallel PARP pathway — … WebMar 6, 2024 · Synthetic lethality has emerged as a useful paradigm for the identification of therapeutic targets in cancer [1].The term was initially used to refer to an incompatibility between pairs of mutations in Drosophila where the presence of either mutation alone was well tolerated but their presence in combination resulted in lethality. However, in the …
WebMay 3, 2024 · The PARP inhibitors work based on a concept called synthetic lethality. Synthetic lethality means you are now using a drug that inhibits the cancer cell’s other mechanisms by which it can repair its DNA damage when one form of DNA repair is already compromised.
