Abstract：
:Calcitriol (1,25-dihydroxyvitamin D3), the active form of vitamin D, promotes growth inhibition and differentiation in prostate cancer (PCa) cells. To unravel the molecular pathways of calcitriol actions, cDNA microarray analysis was used to identify novel calcitriol target genes including two that play key roles in the metabolism of prostaglandins (PGs), known stimulators of PCa growth and progression. Calcitriol significantly decreases the expression of the PG synthesizing cyclooxygenase-2 (COX-2) gene, while increasing that of PG inactivating 15-prostaglandin dehydrogenase (15-PGDH). Calcitriol also inhibits the expression of the PG receptors EP2 and FP. It reduces the levels of biologically active PGs and inhibits PG actions in PCa cells, thereby decreasing the proliferative stimulus of PGs. We postulate that the regulation of the PG pathway contributes to the growth inhibitory actions of calcitriol. We also propose that calcitriol can be combined with non-steroidal anti-inflammatory drugs (NSAIDs) that inhibit COX enzyme activity, as a potential therapeutic strategy in PCa.
