Pathological examination of small intestinal adenomas from the test Fabpl::Cre+/oTdgflox/-ApcMin/+ mice in comparison to adenomas from control Fabpl::Cre+/oTdg+/+ApcMin/+ mice revealed an excess of poorly differentiated tumors, in which the differentiated gland (crypt/villus) architecture had been lost (Figure 2). Here, FABP1 is linked to adenoma of small intestine.
