Figure 1From: Variable copy number of mitochondrial DNA (mtDNA) predicts worse prognosis in advanced gastric cancer patientsCopy number of mtDNA corresponding to each individual case of gastric cancers and normal gastric tissues (circle). Real-time quantitative PCR assay was performed to analyze mtDNA copy number in a cohort of gastric cancers and normal gastric tissues. Horizonal lines represent mean ± S.E. Details are as described in Methods. T, tumor tissues; N, normal gastric tissues.Back to article page
