Project description:The corpus luteum plays a critical role in reproduction because it is the primary source of circulating progesterone. This study aimed to determine the in vitro effect of peroxisome proliferator-activated receptor gamma (PPARγ) ligands on the transcriptome genes expression in the porcine corpus luteum in the mid- and late-luteal phase of the estrous cycle using RNA-seq technology. The corpus luteum slices were incubated in vitro in the presence of PPARγ agonist – pioglitazone and antagonist—T0070907. We identified 40 differentially expressed genes after pioglitazone treatment and 40 after T0070907 treatment in the mid-luteal phase as well as 26 after pioglitazone and 29 after T0070907 treatment in late-luteal phase of the estrous cycle. In addition, we detected differences in genes expression between the mid- and late-luteal phase without treatment (409). These results should become a basis for further studies explaining the mechanism of PPARγ action in the reproductive system in pigs.

Project description:C. Stötzel, J. Plöntzke, W. Heuwieser & S. Röblitz. Advances in modeling of the bovine estrous cycle: synchronization with PGF2α. Theriogenology 78, 7 (2012).
Our model of the bovine estrous cycle is a set of ordinary differential equations which generates hormone profiles of successive estrous cycles with several follicular waves per cycle. It describes the growth and decay of the follicles and the corpus luteum, as well as the change of the key reproductive hormones, enzymes and processes over time. In this work we describe recent developments of this model towards the administration of prostaglandin F2α. We validate our model by showing that the simulations agree with observations from synchronization studies and with measured progesterone data after single dose administrations of synthetic prostaglandin F2α.
