Many of the immune response related (e.g., IRF8, JAK3, PTGER4, RELB, IFITM3) and part of the lipid metabolism related genes (e.g., NR1H4, PPARGC1B, PLIN1, HSD17B14) were identified to be adaptive which addressed their significance for prostate cancer. The gene discussed is HSD17B14; the disease is prostate carcinoma.
