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.

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:Despite much investigation, mechanisms conferring stage specific responsiveness of the corpus luteum (CL) to prostaglandin F2 (PG) are unknown. The objective of this study was to identify PG- induced changes in transcriptome of bovine CL specific to d 11 ( PG responsive) but not d 4 (PG refractory) CL associated with luteolysis. CL were collected from heifers at 0, 4 and 24 h following PG injection on d 4 and 11 of the estrous cycle (n = 5 animals/treatment) and isolated RNA labeled and hybridized to Affymetrix GeneChip Bovine Genome Arrays. At 4 and 24 h post PG respectively, 221 (d 4) and 661 (d 11) and 248 (d 4) and 1419 (d 11) regulated genes were identified.

Project description:In ruminants, prostaglandin F2alpha (PGF2α)-mediated luteolysis is essential for resumption of the estrous cycle and is a target for improving fertility. To deduce the early PGF2α-provoked signaling elicited in the corpus luteum a time-course from 0.5–4 h was performed on cows at mid-cycle. A microarray-determined transcriptome was established and analyzed by Ingenuity Pathway Analysis (IPA). Self-organizing map analysis grouped differentially expressed transcripts into ten mRNA expression patterns indicative of signaling cascades. Classic PGF2α signaling (cyclic adenosine monophosphate, mitogen-activated protein kinases) and cytokine signaling (nuclear factor κB, interleukin) were both predicted by IPA after PGF2α administration. Comparison with two analogous datasets revealed a conserved group of 124 transcripts similarly changed in each dataset, which also predicted cytokine signaling. Elevated levels of cytokine transcripts after PGF2α and IPA-predicted activation of cytokine pathways demonstrate the importance of inflammatory reactions early in PGF2α -mediated luteolysis.

Project description:The corpus luteum (CL), an ovarian transient gland, develops from the remnants of the ovulatory follicle and produces progesterone, required for maintenance of pregnancy in mammals. The development of the CL is characterized by the differentiation of granulosal and thecal cells into luteal cells, cell hypertrophy and hyperplasia. As the CL matures, growth ceases and the tissue acquires the ability to undergo regression in response to luteolytic signals (prostaglandin F2alpha). The regulators of this transition are poorly understood. MicroRNA, posttranscriptional regulators of tissue development and function, are hypothesized to play a role during these processes. The goal of this study was to profile the expression of microRNA (miRNA) in the corpus luteum (CL) of Holstein cows at two time points of the estrous cycle (early-cycle (Day4) and midcycle (D9-12); day0= day of estrus) in order to investigate their role in regulating CL development and function.
