Abstract
BACKGROUND Prostaglandin F2α (PGF2α) is an important component for the physiology of female reproductive processes. In the literature, the data pertaining to the synthesis and action of PGF2α in early embryonic bovine development are limited. In our study, we used the bovine in vitro culture model based on the time of first cleavage to determine the mRNA expression and immunolocalization of PGF2α synthase and its receptor in bovine embryos from the 2-cell stage to the hatched blastocyst stage. We also evaluated PGF2α production at 2, 5 and 7 days of in vitro culture. RESULTS We found a significantly higher proportion of blastocysts obtained from the early-cleaved embryos than from the late-cleaved embryos (37.7% vs. 26.1% respectively, P < 0.05). The PGFS mRNA expression was significantly higher in the late-cleaved group than in the early-cleaved group at the 2-, 4- and 16-cell stages (P < 0.05). For PTGFR, we observed that within the late-cleaved group, the mRNA abundance was significantly higher in embryos at the 2- and 16-cell stages than in embryos at the 4- and 8-cell stages (P < 0.05). We observed that PTGFR mRNA expression was significantly higher in the 2- and 16-cell embryos in the late-cleaved group than that in the early-cleaved group embryos (P < 0.05). Among the blastocysts, the PGFS and PTGFR expression levels showed a trend towards higher mRNA expression in the late-cleaved group than in the early-cleaved group. Analysis of PGF2α production showed that within the early-cleaved group, the content of PGF2α in the in vitro culture medium was significantly higher on day 7 than it was on day 2 (P < 0.05). CONCLUSIONS The mRNA expression levels of PGF2α synthase and its receptor depend on the developmental stage and the embryo quality. Analyses of PGFS and PTGFR expression in bovine blastocysts and of PGF2α embryo production suggest that prostaglandin F2α can act in an autocrine and paracrine manner in bovine in vitro-produced preimplantation embryos. Moreover, the tendency of PTGFR and PGFS mRNA expression to be upregulated in embryos with low developmental potential can indicate a compensation mechanism related to high PGFS and PTGFR mRNA expression levels in low-quality embryos.

Expression of enzymes involved in the synthesis of prostaglandin E 2 in early- and late-cleaved bovine embryos at different stages of preimplantation development. Theriogenology 2019; 133:45-55.

Abstract
Prostaglandin (PG) E2 plays a role in numerous aspects of mammalian reproduction, such as oviductal transport of gametes, hatching from the zona pellucida in blastocysts and early embryonic development. Despite the evident role of PGE2 in the regulation of female reproductive processes, in the literature, there is very little information concerning the expression of PGE2 synthesizing enzymes and the exact amount of PGE2 produced by bovine embryos in vitro. In the present study, we aimed to determine the mRNA levels and immunolocalization of the enzymes responsible for PGE2 synthesis (PTGS2, mPGES1, mPGES2 and cPGES) in embryos at the 2-cell, 4-cell, 8-cell, 16-cell, morula, early blastocyst, blastocyst, expanded blastocyst and hatched blastocyst stages, using a well-defined bovine model of oocyte developmental competence based on the time of first cleavage. PTGS2, mPGES2 and cPGES transcripts and proteins were detected in all stages of embryos, whereas the mPGES1 transcript and protein were not detected in embryos from the 2- to 16-cell stage. The results showed different transcription profiles of the enzymes involved in PGE2 synthesis in early- and late-cleaved embryos during the early stages of their in vitro preimplantation development. We also found that all the analysed stages of bovine preimplantation embryos released PGE2, with the highest concentration on Day 7 of culture in both the early- and late-cleaved groups. The present study is the first to demonstrate PGE2 synthesis and production by bovine early- and late-cleaved embryos at different stages of preimplantation development. Bovine embryos can produce PGE2, which may exert paracrine regulation during development. The transcription levels of PGE2 synthases were affected by the embryonic stage of development and quality. Our results indicate that the different transcription profiles of PTGS2, mPGES1, mPGES2 and cPGES, as well as PGE2 concentration, in early-versus late-cleaved embryos are dependent on the quality of the oocytes from which the embryos were obtained, which could reveal the association of PGE2 production during bovine preimplantation development with more advanced stages of embryo development.

Abstract
Assisted reproduction technologies (ART) and high selection pressure in the dairy industry are leading towards the use of younger females for reproduction, thereby reducing the interval between generations. This situation may have a negative impact on embryo quality, thus reducing the success rate of the procedures. This study aimed to document the effects of oocyte donor age on embryo quality, at the transcriptomic level, in order to characterize the effects of using young females for reproduction purpose. Young Holstein heifers (n = 10) were used at three different ages for ovarian stimulation protocols and oocyte collections (at 8, 11 and 14 months). All of the oocytes were fertilized in vitro with the semen of one adult bull, generating three lots of embryos per animal. Each animal was its own control for the evaluation of the effects of age. The EmbryoGENE platform was used for the assessment of gene expression patterns at the blastocyst stage. Embryos from animals at 8 vs 14 months and at 11 vs 14 months were used for microarray hybridization. Validation was done by performing RT-qPCR on seven candidate genes. Age-related contrast analysis (8 vs 14 mo and 11 vs 14 mo) identified 242 differentially expressed genes (DEGs) for the first contrast, and 296 for the second. The analysis of the molecular and biological functions of the DEGs suggests a metabolic cause to explain the differences that are observed between embryos from immature and adult subjects. The mTOR and PPAR signaling pathways, as well as the NRF2-mediated oxidative stress response pathways were among the gene expression pathways affected by donor age. In conclusion, the main differences between embryos produced at peri-pubertal ages are related to metabolic conditions resulting in a higher impact of in vitro conditions on blastocyts from younger heifers.

Effect of cow age on the in vitro developmental competence of oocytes obtained after FSH stimulation and coasting treatments. Theriogenology 2016; 86:1240-6.

Abstract
The use of oocytes obtained from younger donors for IVF followed by embryo transfer represents an opportunity to accelerate genetic gain by reducing generation time. In this study, we investigated the relationship between donor age and the in vitro developmental competence of oocytes obtained from Holstein females (aged 5-18 months) after FSH stimulation and coasting. The follicle size patterns showed a significantly higher total number of small follicles (5-6 mm) from donors aged 5 to 10 months and a higher total number of medium-sized follicles (7-10 mm) in donors aged 6 to 7 months. Our analysis also revealed that the total number of follicles was significantly higher (P < 0.05) in donors aged 5 to 8 months and tended to be higher (P = 0.053) in nine-month-old donors. However, oocytes obtained from donors aged 5 to 10 months yielded fewer embryos reaching the morula and blastocyst stages. In summary, our results demonstrate that a higher number of oocytes can be obtained from younger animals but lower developmental competence negates this gain.
