Previously, the TMEs of non–small-cell lung cancer (NSCLC), melanoma, pancreatic cancer, prostate cancer, bladder cancer, soft tissue sarcoma, and breast cancer were analyzed using DSP, but mainly on the protein expression (Ihle et al., 2019; Toki et al., 2019; Cabrita et al., 2020; Gundle et al., 2020; Stewart et al., 2020; Zugazagoitia et al., 2020). The gene discussed is DSP; the disease is urinary bladder cancer.
