Figure 1From: Is cumulative frequency of mitochondrial DNA variants a biomarker for colorectal tumor progression?Frequencies of mitochondrial genome variants based on high-restriction analysis in all of the colorectal tumors (tubular, tubulovillous, villous), cancer tissues in each of the 9 primer sets. Numbers on the abscissa represent PCR products obtained using overlapping primers sets 1–9, termed haploblocks (Rank methods; for all comparsion).Back to article page
