Figure 3From: The mitochondrial DNA 4,977-bp deletion and its implication in copy number alteration in colorectal cancer Relationship between mtDNA content and the 4,977-bp deletion level. The deletion level in tumor (closed circle and solid line) and non-tumor (open circle and dot line) tissues from 20 patients who carried the deletion are plotted against the mtDNA content. R2 indicates the strength of a linear relationship between the two parameters.Back to article page
