Demonstratively, prostate cancer adenocarcinoma (PRAD) is identified via NKX3-1, a distinct marker of prostatic cancers37, as well as other genes such as PCA3, and FOLH1. For melanoma (SKCM), UCDBase associates it with the expression of MLANA, the melanoma diagnostic antigen melanin-A38, as well as genes such as TRYP1 and MTRNR2L2. Further inspection of the abovementioned gene features and others (see Supplementary Table 2) demonstrates UCDBase learned subtype-specific gene representations that appear to corroborate their relevance as suggested in prior studies. Here, PCA3 is linked to melanoma.
