Characterization of NEPC: (A) Tumor with mixed features of NEPC and PCA. Hematoxylin and eosin (H&E) staining, immunohistochemical analysis for androgen receptor (AR) and ERG, and FISH for ERG breakapart (indicating gene fusion) (B) Gene expression of the 936 of 25932 genes showing differential expression between 7 NEPC cases and 30 PCAs, after a Benjamini-Hochberg correction for multiple hypothesis testing of <0.001 (Red =High Expression, Green = Low Expression). (C) Gene Expression of select genes comparing NEPC and PCA, including neuroendocrine associated genes (SYP, CHGB, CHGA), EZH2, MIB1 (Ki67), PSMA, AR, and androgen regulated genes (NKX3-1, KLK3 (PSA), TMPRSS2). (D) Graphical representation of the genomic landscape of PCA (in order of increasing Gleason Score) and NEPC, as determined by Affymetrix 6.0 oligonucleotide array (Red= Copy Number Gain, Blue= Copy Number Loss, White= No Change).
