From: Deficient expression of DNA repair enzymes in early progression to sporadic colon cancer
A Venn diagram illustrating the level of concordance of deficiencies of Pms2, Ercc1 and XPF. Entire tissue sections were evaluated with respect to all crypt absorptive cells seen in the tissue or within all cells of epithelial origin within a cancer. Pms2, Ercc1 and Xpf were evaluated in triplicate sequential 4 micron tissues sections of the same tissue samples.
