We have reported that *Cu-ATSM is trapped in tumor cells under over-reduced states, such as hypoxia. In this study, to evaluate *Cu-ATSM as an indicator of intracellular over-reduced states in disorders with mitochondrial dysfunction, we examined correlation between *Cu-ATSM uptake and levels of biological reductant NADH and NADPH with mtDNA (mitochondria DNA)-less 0 cells and the parental 143B human osteosarcoma cells and with 0-cybrids carrying mutated mitochondria from a patient of mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) (2SD cells) and that carrying wild-type one (2SA cells)., 2011 World Molecular Imaging Congress (Wmic)}, title = {Radiolabeled Cu-ATSM as a novel indicator of over-reduced states in mitochondrial disorders: studies with mtDNA-less 0 cells and the cybrids carrying MELAS mtDNA mutation}, year = {2011} }
