Groups: normal, AOM only, AOM + 0.2% (w/v) of IP6, AOM + 0.5% (w/v) of IP6, AOM + 1% (w/v) of IP6, and (IP6: inositol hexaphosphate, AOM: azoxymethane). Values in the same column with different superscript indicate significant difference by the Tukey’s test ( ). Adenoma is defined as a benign tumor of glandular origin. Adenocarcinoma is a malignant tumor originating in glandular epithelium. Total tumor consists of both adenoma and adenocarcinoma in the colon tumor tissue.
