However, the expression of TMPRSS2 in breast invasive cancer (BRCA), esophageal cancer (ESCA), head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), rectal adenocarcinoma (READ), sarcoma (SARC), skin cutaneous melanoma (SKCM), testicular germ cell tumor (TGCT), and thyroid cancer (THCA), including lung squamous cell carcinoma (LUSC), was downregulated (Figure 4). The gene discussed is TMPRSS2; the disease is invasive breast carcinoma.
