Prostaglandins (PGs) play important physiological and therapeutic roles in the eye. Our laboratory recently identified a novel PG transporter in the rat that we call 'PGT' (Science 268:866, 1995). We have also recently cloned the human PGT cDNA (J Clin Invest 98:1142, 1996). To determine whether PGT might play a role in human ocular tissues, we performed Northern blot analysis of RNA obtained from human ocular tissues and from the nonpigmented ciliary epithelium cell line 'ODM-2.' PGT transcripts were clearly evident in all ocular tissues. Given that the functional profile PGT expressed in vitro strongly suggests a role in PG uptake and degradation, the present results suggest that PGT may function in various regions of the human eye for purposes of terminating the signal(s) produced by locally-synthesized PGs.
