| Outline of Final Research Achievements |
We established a cell model of rat embryonic myoblasts in which azidothymidine triphosphate (AZT-TP), active metabolites of AZT, that is anti-HIV (human immunodeficiency virus) drug accumulates in a short time. Using this cell model, it was found that lethal cardiac dysfunction due to long-term administration of AZT is caused by accumulation of AZT-TP. Furthermore, as a detailed mechanism of cytotoxicity, accumulation of AZT-TP causes impairment of the mitochondrial quality control system, damage of mitochondrial electron transport chain and increasing reactive oxygen species (ROS) produciton in the cell, that induce apoptosis and cell death.
