When comparing differentially expressed proteins with prostate adenocarcinoma TCGA data, we identified 37 proteins (ACAT2, EIF3D, FKBP8, DHX9, EIF5, HNRNPA3, PPP6C, SSMP1, UBE2M, etc.)that showed consistency between N0 versus N1 and PC3‐P versus PC3‐R data. This evidence concerns the gene HNRNPA3 and prostate adenocarcinoma.
