Research Abstract |
The insulin-like growth factors (IGFs) were multifunctional growth factor involved in the development, growth and survival of tumor cells. Familial adenomatous polyposis (FAP) develops a large number of pre-malignant adenomatous polyps during adolescence which become colon cancers at high rates. IGF-I or IGF-II neutralizing antibody was administered to FAP model mouse and each antibody significantly reduced the number of small intestinal polyp, respectively. Combination administration in the effective dose of each antibody had the synergistic effect. Our findings demonstrate that IGFs in the tumor microenvironment play a crucial role for the colon tumorigenesis and may be the promising therapeutic target.
