Correlation analyses revealed that average expression of the TGFβ-regulated EMT signature and the REACTOME gene set “Signaling by TGF beta receptor complex” were positively correlated in breast invasive carcinomas (BRCA), lung squamous cell carcinomas (LUSC), colon adenocarcinomas (COAD) and pancreatic adeno-carcinomas (PAAD) (Figure 8a). This evidence concerns the gene TGFB1 and pancreatic adenocarcinoma.
