In addition to TCGA data analysis, we also analyzed the expression levels of the five proteins from the DHT-specific protein, LDHB as well as FSK-specific proteins, IMPDH2, HNRNPK, OXCT1, and ACPP in protein carcinomas, including hormone refractory prostate cancer and metastatic prostate cancer samples in several publicly available datasets. This evidence concerns the gene HNRNPK and metastatic prostate carcinoma.
