| pubmed-article:2953339 | pubmed:abstractText | Adriamycin caused significant interphase death in HL-60 cells during six hours of incubation, which was abolished by the poly(ADP-ribose) polymerase inhibitors, 3-aminobenzamide or nicotinamide. Neither agent changed adriamycin uptake by HL-60 cells. Although 3-aminobenzamide did not alter the number of DNA strand breaks caused by adriamycin, it prevented adriamycin-induced depletion of intracellular NAD+ and ATP, and maintained energy charge. These findings suggest that the activation of poly(ADP-ribose) synthesis plays an important role in the adriamycin-induced interphase death of proliferating HL-60 cells. | lld:pubmed |
