Synthetic Lethality: Molecular Targeted Therapy

sl.png

Synthetic lethality A synthetic lethal interaction occurs between two genes when the perturbation of either gene alone is viable but the perturbation of both genes simultaneously results in the loss of viability. Key to exploiting synthetic lethality in cancer treatment are the identification and the mechanistic characterization of robust synthetic lethal genetic interactions. First example of a molecular targeted therapeutic exploiting a synthetic lethal exposed by an inactivated tumor suppressor gene (BRCA1 and 2) receiving FDA approval in 2016 (PARP inhibitor)
