Mcl-1 downregulation by mda-7 / IL-24 relieved its association with the proapoptotic protein Bak , causing oligomerization of Bak and leading to cell death.
48 h later , Western blotting was used to detect the protein expression of mda-7 / IL-24 in the MCF-7 cells.
Exogenous expression of Gene 33 in MCF-7 cells did not affect cell cycle distribution , but inhibited apoptosis and specifically increased the level of Poly (ADP-ribose) Polymerase (PARP-1) protein.
A novel class of quinazolinone derivatives as potent poly (ADP-ribose) polymerase-1 (PARP-1) inhibitors has been discovered.
