Incidence of low grade dysplasia in either 1.five DSS or cycles DSS-treated Smad32/2 mice was substantially higher (P = 0.0002 and 0.0461, respectively, Fisher exact test) thanPLOS 1 | plosone.orgSmad32/2 animals offered untreated water. Low grade dysplasia was not detected in any DSS-treated WT or Smad3+/2 mice (Figure 8B).DSS-Induced Colitis in Smad32/2 Micewith regions of typical proximal colon (A) mucosal adenomatous hyperplasia (B) and mucinous adenocarcinoma (C and D) immunohistologically stained for galectin-3. (A) In regular proximal colonic mucosa, galectin-3 expression is restricted to well-differentiated apical colonocytes with strong nuclear and lesser cytoplasmic signal. (B) Inside adenomas there is loss of signal within the proliferative cells (arrows, mitotic figures) and staining cytoplasmic signal with indistinct to absent nuclear signal. (C) Within invasive crypts deep inside the tunica muscularis (see A) there is certainly loss of signal with gradual raise in signal as cells migrate into the peritoneal cavity and presumably differentiate to a mucinous p.
