digestive/alimentary system
abnormal crypts of Lieberkuhn morphology ( J:96380 )
• the proliferative zone is enlarged
abnormal colon morphology ( J:96380 )
• colonocyte proliferation is significantly increased

endocrine/exocrine glands
abnormal crypts of Lieberkuhn morphology ( J:96380 )
• the proliferative zone is enlarged

homeostasis/metabolism
abnormal homeostasis ( J:96380 )
• the ratio of S-adenosylmethionine to S-adenosylhomocysteine is decreased in the plasma
increased physiological sensitivity to xenobiotic ( J:96380 )
• 8 weeks after treatment with azoxymethane more aberrant crypts per focus are found in heterozygotes compared to wild-type mice
• 38 weeks after treatment with azoxymethane, inflammatory lesion size is increased however the number of lesions is the same as in wild-type mice
