Interestingly, a recent paper that examined gene expression in mouse models of colon carcinoma in a developmental context revealed a distinction between Smad3-/- and Tgfb1-/-; Rag2-/- models (both exhibiting a strong inflammatory component and showing similarity to late colon development) and ApcMin/+ and AOM models, which recapitulated early colon development [10]. The gene discussed is SMAD3; the disease is colon carcinoma.
