Abstract excerpt
p53 and poly(ADP-ribose) polymerase (PARP) are both DNA damage recognition proteins and can be functionally activated by DNA strand breaks. To understand the functional interaction between these two proteins, the effects of a PARP inhibitor, 3-aminobenzamide (3AB), on the p53 pathway were investigated in human glioblastoma cells with different p53 status. Consistent with previous studies, irradiation with...
