To gain further insight into the role of TGFβ signaling at the early stages of tumor development in vivo, we generated gene expression data from a set of TA and SSA polyps (GSE45270 and GSE79460) and analyzed the expression of the five most strongly induced and five most strongly reduced genes upon TGFβ treatment of TA organoid cultures. Here, TGFB1 is linked to neoplasm.
