12-HETER1/GPR31, a high-affinity 12(S)-hydroxyeicosatetraenoic acid receptor, is significantly up-regulated in prostate cancer and plays a critical role in prostate cancer progression.


ABSTRACT: Previously we identified and deorphaned G-protein-coupled receptor 31 (GPR31) as the high-affinity 12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE] receptor (12-HETER1). Here we have determined its distribution in prostate cancer tissue and its role in prostate tumorigenesis using in vitro and in vivo assays. Data-mining studies strongly suggest that 12-HETER1 expression positively correlates with the aggressiveness and progression of prostate tumors. This was corroborated with real-time PCR analysis of human prostate tumor tissue arrays that revealed the expression of 12-HETER1 positively correlates with the clinical stages of prostate cancers and Gleason scores. Immunohistochemistry analysis also proved that the expression of 12-HETER1 is positively correlated with the grades of prostate cancer. Knockdown of 12-HETER1 in prostate cancer cells markedly reduced colony formation and inhibited tumor growth in animals. To discover the regulatory factors, 5 candidate 12-HETER1 promoter cis elements were assayed as luciferase reporter fusions in Chinese hamster ovary (CHO) cells, where the putative cis element required for gene regulation was mapped 2 kb upstream of the 12-HETER1 transcriptional start site. The data implicate 12-HETER1 in a critical new role in the regulation of prostate cancer progression and offer a novel alternative target for therapeutic intervention.-Honn, K.
