Using adavosertib-encapsulated MOFs for p53-mutated gallbladder cancer treatment via synthetic lethality

Physorg.com - 14 марта, 2024 - 22:49
Since the revelation of poly(ADP-ribose) polymerase (PARP) inhibitors and their remarkable results in the treatment of BRCA1/2 mutant cancers, synthetic lethality (SL) in antitumor therapy has attracted increasing attention. SL is a phenomenon in which a single genetic event is insufficient to induce cell death, but multiple genetic events lead to cell death.
