Not only in colorectal cancer (COAD), but TNFRSF18 and CXCL13 also have higher expression in tumour tissues across multiple tumour types, including breast cancer (BRCA) and stomach cancer (STAD), indicating that they may serve as a target for a broad range of cancers (Figure S2C,D). The gene discussed is TNFRSF18; the disease is breast cancer.
