PPAR delta functions as a prostacyclin receptor in blastocyst implantation
1Division of Genetics, Brigham and Women's Hospital and Harvard Medical School, 20 Shattuck Street, Thorn 1010, Boston, MA 02115, USA.
Abstract:
Peroxisome proliferator-activated receptors (PPARs), members of the nuclear hormone superfamily, are the target of extensive investigation because of their role in various pathophysiological processes. Recently, a novel biological function of PPAR delta, a less studied member of the family, was observed in the mouse. Evidence suggests that cyclooxygenase 2-derived prostacyclin mediates blastocyst implantation via this receptor. In this review, this new function of PPAR delta in implantation is highlighted, and future directions to investigate its mechanism of action are discussed.
Insights
Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors involved in many processes. PPAR delta plays a newly discovered role in mediating mouse blastocyst implantation via prostacyclin.
