The Potential Applications of Peroxisome Proliferator-Activated Receptor δ Ligands in Assisted Reproductive Technology

Abstract EN

Peroxisome proliferator-activated receptor δ (PPARδ, also known as PPARβ) has ubiquitous distribution and extensive biological functions.

The reproductive function of PPARδ was first revealed in the uterus at the implantation site.

Since then, PPARδ and its ligand have been discovered in all reproductive tissues, including the gametes and the preimplantation embryos.

PPARδ in preimplantation embryos is normally activated by oviduct-derived PPARδ ligand.

PPARδ activation is associated with an increase in embryonic cell proliferation and a decrease in programmed cell death (apoptosis).

On the other hand, the role of PPARδ and its ligand in gamete formation and function is less well understood.

This review will summarize the reproductive functions of PPARδ and project its potential applications in assisted reproductive technology.
