Fig. 7From: Mitochondrial DNA abnormalities provide mechanistic insight and predict reactive oxygen species-stimulating drug efficacyPositive correlations between the numbers of functional variations predicted in the complex I & III coding regions and baseline ROS levels (a), mitochondrial superoxide levels (b), CDDP IC50s (c) and DQA IC50s (d). Data points representing the cell lines are in the sequence of PNT-2, Ishikawa, MDA-MB-231, PC-3 and Caco-2. r and p and values were calculated using the Pearson correlation coefficient method; *p < 0.05 and **p < 0.01Back to article page
