In humans, thromboxane (TX) A2 signals through two receptor isoforms, thromboxane receptor (TP)aand TPb, which are transcriptionally regula-ted by distinct promoters, Prm1 and Prm3, respectively, within the single TP gene. The aim of the current study was to investigate the ability of the endogenous peroxisome proliferator-activated receptor (PPAR)c ligand 15-deoxy-D 12,14 -prostaglandin J2 (15d-PGJ2) to regulate expression of the human TP gene and to ascertain its potential effects on the individual TPa and TPbisoforms
