WebApr 8, 2024 · PARP inhibitors induce synthetic lethality in BRCA1/2 defective cells. Synthetic lethality is a situation in which mutations in two genes together cause cell death, whereas mutation in either gene alone does not. Cancer cells that have only one mutated gene in a specific pair of genes may depend on the normal partner gene for existence. Webmerase (PARP) enzymes play a key role in BER, and PARP inhibitors are effective in causing cell death in BRCA-mutant cells while sparing normal cells—a concept called synthetic … mercury filmworks addressWebPARP-Inhibitoren kommen derzeit vor allem als Erhaltungstherapie ("second line") nach einer primären erfolgten Chemotherapie zur Anwendung.
