Expression of the Cyclin D1 protein in pericarcinoma and rectal cancer tissues (× 400). A and B. Positive and low cytoplasmic expression of Cyclin D1 in pericarcinoma rectal tissues; C. Negative expression in pericarcinoma rectal tissues; D. High expression in the cytoplasm in poorly differentiated rectal adenocarcinoma tissues; E. Positive expression in the cytoplasm in poorly differentiated rectal mucinous adenocarcinoma tissues; F. Positive expression in the cytoplasm in moderately differentiated rectal adenocarcinoma tissues; G and H. Negative expression in moderately differentiated rectal adenocarcinoma and signet-ring cell carcinoma tissues.
