Figure 5A depicts a section of normal seminiferous tubule having positive nuclear staining for CABYR antigen on germ cells. Figure 5B depicts stained colonic adenocarcinoma having 3+ positive nuclear staining for CABYR antigen, and Figure 5C depicts a section of adjacent normal colonic tissue having negative staining for CABYR antigen. This evidence concerns the gene CABYR and colon adenocarcinoma.
