| Caption | Rab25 deficiency promotes colon tumor formation and neoplasia in Smad3tm1Par/Smad3+ mice. (A) Smad3tm1Par/Smad3+ mice on a Rab25+/Rab25+ background (Smad3+/-Rab25+/+) did not show any adenomas in their colons. (B) Higher magnification of view of A shows normal colonic mucosa. (C) Swiss roll of Smad3tm1Par/Smad3+ Rab25tm1Jrgo/Rab25tm1Jrgo mouse (Smad3+/-Rab25-/-) colon. Note the numerous mucin-filled cysts. The image was captured using an Ario SL-50 imager. Areas of the image in which no tissue was present appear blank. (D) In a more aggressive proximal tumor, the cancerous lesions penetrated into the serosal wall with neoplastic atypical cystic glands filled with mucin. (E) The neoplastic colonic epithelium invaded into and through the submucosa, and the neoplastic glands invaded the muscle wall. (F) Rectal area of Smad3tm1Par/Smad3+ Rab25tm1Jrgo/Rab25tm1Jrgo mice. The neoplastic colonic epithelium penetrated muscle wall with atypical cystic glands filled with mucin. (G) Atypical cystic glands in epithelium and penetrating the muscle wall. (H) Vagina neoplasia. In vaginal epithelium, neoplastic squamous epithelial cells invaded the muscle layer. The vaginal lesions were not specific to ApcMin/Apc+ mice and were seen in Rab25-deficient mice on the 129 background. Scale bars: 1 mm. | ||||||
