Human TMAs were stained for the following markers: luminal or basal epithelial (AR, NKX3.1, CK8, and P63), neuroendocrine (SYP, INSM1, ASCL1, NEUROD1 and FOXA2), cell surface (TROP2 and DLL3), proliferation (KI67), as well as other markers of interest from scRNA–seq analyses of prostate cancer GEMMs (YAP1, POU2F3, MYC, SOX2, TFF3, and EZH2) (17–19) (Figure 1A, Supplementary Table 1). The gene discussed is EZH2; the disease is Familial prostate cancer.
