Peroxisome proliferator activated receptor ligands affect porcine endometrial steroids production during the estrous cycle and early pregnancy:an in vitro study
PPAR progesterone estradiol luteal phase periimplantation
<
2016/9/1
In the present study, we investigated the effect of PPAR ligands on progesterone (P4) and 17β-estradiol (E2) secretion, as well as 3β-hydroxysteroid dehydrogenase/Δ(5)-Δ(4) isomerase (3β-HSD) mRNA exp...
