Shortened villi in the small intestine of Cdc25atm1Hpw/Cdc25atm1.1Hpw Cdc25btm1Pjd/Cdc25btm1Pjd Cdc25ctm1Hpw/Cdc25ctm1Hpw Gt(ROSA)26Sortm1(cre/ERT)Brn/Gt(ROSA)26Sor+ (TKO) mice

mortality/aging
• adult mice die within 1 week of initial 4-hydroxytamoxifen (OHT) injection

growth/size/body
• adult mice exhibit significant weight loss (20%) within 1 week of initial tamoxifen injection

digestive/alimentary system
• profound cell atrophy in the crypts is observed in OHT-treated mice; crypts are >40% smaller in mutants than Cdc25a-single knockout controls, with the crypt width being decreased more significantly than the depth
• a 70% loss of epithelial cells per crypt is detected, but no difference in mature Paneth cells is observed
• decreased proliferation of epithelial cells is observed, with no significant increase in apoptotic cell numbers; this results in premature differentiation of cell progenitors below Paneth cell compartments in crypts
• crypts have increased numbers of cells exhibiting early differentiation with no crypt base columnar (CBC) cells
• villi are lined with shorter, less-dense enterocytes in proximal regions; complete loss of distal villi is observed in some areas
• significant loss of villus height in proximal and distal regions is observed in mutants after OHT treatment
• 6 days following the final of 3 consecutive injections of tamoxifen, length of small intestine is shortened by 40% compared to controls

endocrine/exocrine glands
• profound cell atrophy in the crypts is observed in OHT-treated mice; crypts are >40% smaller in mutants than Cdc25a-single knockout controls, with the crypt width being decreased more significantly than the depth
• a 70% loss of epithelial cells per crypt is detected, but no difference in mature Paneth cells is observed
• decreased proliferation of epithelial cells is observed, with no significant increase in apoptotic cell numbers; this results in premature differentiation of cell progenitors below Paneth cell compartments in crypts
