Project description:Chemoprevention is a pragmatic approach to reduce the risk of colorectal cancer, one of the leading causes of cancer-related death in western countries. In this regard, maslinic acid (MA), a pentacyclic triterpene extracted from wax-like coatings of olives, is known to inhibit proliferation and induce apoptosis in colon cancer cell lines without affecting normal intestinal cells. The present study evaluated the chemopreventive efficacy and associated mechanisms of maslinic acid treatment on spontaneous intestinal tumorigenesis in Apc(Min/+) mice. Twenty-two mice were randomized into 2 groups: control group and MA group, fed with a maslinic acid-supplemented diet for six weeks. MA treatment reduced total intestinal polyp formation by 45% (P<0.01). Putative molecular mechanisms associated with suppressing intestinal polyposis in Apc(Min/+) mice were investigated by comparing microarray expression profiles of MA-treated and control mice and by analyzing the serum metabolic profile using NMR techniques. The different expression phenotype induced by MA suggested that it exerts its chemopreventive action mainly by inhibiting cell-survival signaling and inflammation. These changes eventually induce G1-phase cell cycle arrest and apoptosis. Moreover, the metabolic changes induced by MA treatment were associated with a protective profile against intestinal tumorigenesis. These results show the efficacy and underlying mechanisms of MA against intestinal tumor development in the Apc(Min/+) mice model, suggesting its chemopreventive potential against colorectal cancer.

Project description:C57BL/6 mice with a tamoxifen (TAM)-inducible disruption of Apc (CDX2P-CreERT2;Apc fl/fl) or Apc and Dhps (CDX2P-CreERT2;Apc fl/fl;Dhps fl/fl) were injected or not with one intraperitoneal injection 4.5 mg/kg TAM. After 35 days, the following colon biopsies were harvested: normal tissues from mice that did not receive TAM, non-tumor tissues from mice treated with TAM, and tumors from mice treated with TAM. Biopsies from 5 mice were collected for the following sample groups: (1) Apc Control; (2) Apc/Dhps Control; (3) Apc+TAM non-tumor; (4) Apc/Dhps+TAM non-tumor; (5) Apc+TAM tumor; (6) Apc/Dhps+TAM tumor
