A. Immunohistochemical staining for PCNA in intestinal tumors from APCMin/+ mice fed control diet or treated with licofelone.
B. Significant difference was observed in proliferative index between licofelone-treated and control group polyps.
C. TUNEL assay was performed for apoptotic cells in intestinal tumors from APCMin/+ mice fed control diet or treated with licofelone. A significant induction of apoptosis was observed in hyperplastic regions and polyps of treated mice compared with untreated mice.
D. A significant difference was observed in apoptotic index between licofelone-treated and control groups. Polyps from treated showed ~75% induction of apoptosis compared with polyps from control mice.
