Abstract
Dairy cow subfertility is a worldwide issue arising from multiple factors. It manifests in >30% early pregnancy losses in seasonal pasture-grazed herds, especially when cows are inseminated in the early post-partum period. Most losses occur before implantation, when embryo growth depends on factors present in maternal tract fluids. Here we examined the proteomic composition of early and mid-postpartum uterine luminal fluid in crossbred lactating dairy cows to identify molecular determinants of fertility. We also explored changes in uterine luminal fluid from first to third estrus cycles postpartum in individual cows, linking those changes with divergent embryo development. For this, we flushed uteri of 87 cows at day 7 of pregnancy at first and third estrus postpartum, recovering and grading their embryos. Out of 1563 proteins detected, 472 had not been previously reported in this fluid, and 408 were predicted to be actively secreted by bioinformatic analysis. The abundance of 18 proteins with roles in immune regulation and metabolic function (e.g. cystatin B, pyruvate kinase M2) was associated with contrasting embryo quality. Matched-paired pathway analysis indicated that, from first to third estrus postpartum, upregulation of metabolic (e.g. creatine and carbohydrate) and immune (e.g. complement regulation, antiviral defense) processes were related to poorer quality embryos in the third estrus cycle postpartum. Conversely, upregulated signal transduction and protein trafficking appeared related to improved embryo quality in third estrus. These results advance the characterization of the molecular environment of bovine uterine luminal fluid and may aid understanding fertility issues in other mammals, including humans.

Metabolomic prediction of pregnancy viability in superovulated cattle embryos and recipients with fourier transform infrared spectroscopy. BIOMED RESEARCH INTERNATIONAL 2014; 2014:608579. [PMID: 24834432 PMCID: PMC4009133 DOI: 10.1155/2014/608579] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/24/2014] [Accepted: 03/30/2014] [Indexed: 12/31/2022]
Abstract
We analyzed embryo culture medium (CM) and recipient blood plasma using Fourier transform infrared spectroscopy (FTIR) metabolomics to identify spectral models predictive of pregnancy outcome. Embryos collected on Day 6 from superovulated cows in 2 countries were individually cultured in synthetic oviduct fluid medium with BSA for 24 h before embryo transfer. Spent CM, blank controls, and plasma samples (Day 0 and Day 7) were evaluated using FTIR. The spectra obtained were analyzed. The discrimination capability of the classifiers was assessed for accuracy, sensitivity (pregnancy), specificity (nonpregnancy), and area under the ROC curve (AUC). Endpoints considered were Day 60 pregnancy and birth. High AUC was obtained for Day 60 pregnancy in CM within individual laboratories (France AUC = 0.751 ± 0.039, Spain AUC = 0.718 ± 0.024), while cumulative data decreased the AUC (AUC = 0.604 ± 0.029). Predictions for CM at birth were lower than Day 60 pregnancy. Predictions with plasma at birth improved cumulative over individual results (Day 0: France AUC = 0.690 ± 0.044; Spain AUC < 0.55; cumulative AUC = 0.747 ± 0.032). Plasma generally predicted pregnancy and birth better than CM. These first results show that FTIR metabolomics could allow the identification of embryos and recipients with improved pregnancy viability, which may contribute to increasing the efficiency of selection schemes based on ET.

Abstract
Studies in somatic cells have shown that glucocorticoids such as dexamethasone (DEX) may trigger or prevent apoptosis depending on the cell type in culture. Because the dysregulation of apoptosis may lower in vitro embryo production efficiency, we sought to investigate the effects of supplementing IVC medium with DEX (0.1 μg/mL) on embryo morphology, development kinetics, and apoptosis rates of in vitro-produced bovine preimplantation embryos. Embryo morphology was graded on Day 7, and development rates were assessed on Days 4 and 7 of IVC. Apoptosis was evaluated via annexin/propidium iodide staining under fluorescence microscopy where a cell labeled with annexin, propidium iodide, or both would be considered apoptotic. An embryo was counted in the apoptosis rates, if it displayed at least one such labeled cell. Although DEX supplementation did not reduce apoptosis rates, it had a positive impact on developmental kinetics and cell number both on Days 4 and 7 of embryo culture. Presumably, such effect resulted from increased cell proliferation rather than a direct inhibition of apoptosis. Further studies may evaluate the mechanisms by which glucocorticoids may affect embryo development, as DEX supplementation could become a tool to improve in vitro embryo yield in mammalian species.
