GPR31 and prostate carcinoma: Interestingly enough, a very recent report49 identified the 12(S)-Hydroxyeicosatetraenoic acid (12-HETE) receptor (GPR31, 12-HETER) in prostate cancer tissue, further linking arachidonic acid metabolites as novel potent modulators of prostate growth and providing further elements for novel therapeutic approaches in this disease.
