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. The gene discussed is ACP3; the disease is metastatic prostate carcinoma.
