Similarly, TGFA expression is also reduced in breast invasive carcinoma (BRCA), colon cancer (COAD), glioblastoma multiforme (GBM), chromophobe tumour of the kidney (KICH), hepatocellular carcinoma (LIHC), prostate adenocarcinoma (PRAD) and rectal adenocarcinoma (READ) compared to normal tissue, as shown in Figure 1A. Here, TGFA is linked to invasive breast carcinoma.
