Project description:The aim of this study was to examine changes in the miRNA transcriptional profile of spermatozoa in Holstein-Friesian bulls. Spermatozoa from bulls divergent for feritlity status were used for this study with 10 High fertility bulls and 10 Low fertility bulls. RNA was extracted and subsequently subjected to miRNAseq analysis. 13 miRNA were identified as differentially expressed in the spermatozoa between bulls of high and low feritlity status.

Project description:Objective: To study the uptake by human embryos of extracellular vesicles secreted by the maternal endometrium, and to investigate their miRNA cargo, in order to describe their role in implantation and early embryo development. Design: Prospective descriptive study. Subjects: Healthy women oocyte donors with confirmed fertility and day 5 human blastocysts. Intervention: Endometrial biopsies were collected from healthy oocyte donors undergoing transvaginal ultrasound-guided cyst aspiration for oocyte retrieval. Main Outcome Measures: Extracellular vesicle were isolated from culture media of primary human endometrial epithelial cells by ultracentrifugation. Concentration and size were analyzed by nanoparticle tracking analysis, their morphology visualized by transmission electron microscopy and extracellular vesicle protein markers expression was determined by western blotting. Vesicles were fluorescently labelled with Bodipy-TR ceramide, and their uptake by human blastocysts was analyzed using confocal microscopy. Analysis of the miRNA cargo of extracellular vesicles was performed using miRNAseq, target genes of the most expressed miRNAs were annotated and functional enrichment analysis was performed. Results: Extracellular vesicle characterization revealed a size within 100-300 nm, and expression of extracellular vesicle protein markers HSP70, TSG101, CD9 and CD81. Fluorescent microscopy showed an efficient extracellular vesicle internalization by human blastocysts within 1-2h, being the fluorescent signal stronger in the hatched area of the embryo. miRNAseq described 149 annotated miRNAs and top 37 most expressed miRNAs targeted 6,592 genes. Functional enrichment analysis of these targeted genes indicated that they participate in several processes related to embryo development, oxygen metabolism, cell cycle, cell differentiation, apoptosis, metabolism, cellular organization or gene expression. Among miRNAs contained in these EVs, hsa-miR-92a-3p, hsa-let-7b-5p, hsa-miR-30a-5p, hsa-miR-24-3p, hsa-miR-21-5p and hsa-let-7a-5p were highly implicated in all these biological processes. Conclusion: Data suggest that extracellular vesicles secreted by human endometrial epithelial cells are internalized by human blastocysts, and transport miRNAs to modulate biological processes related to implantation events and early embryo development. Knowledge of the communication system between human endometrium and embryo via miRNA cargo of these vesicles could describe new biomarkers of implantation success and embryo competence.

Project description:MicroRNAs are conserved small non-coding RNAs that act post-transcriptionally to orchestrate a wide spectrum of physiological and pathological processes in stem cells and in human cancers.

Project description:The aim of this study was to measure the impact of contrasting feeding regimes in the first 12 wk of life, known to impact age at puberty on the molecular control of the testes in bull calves. Holstein bull calves were designated to high (HI; n=15) or moderate (MOD; n=15) dietary groups, with diets designed to provoke growth rates of 1.0 and 0.5 kg/day, respectively. At 12 wk of age, all calves were euthanized, and testes parenchyma harvested. RNA was extracted from the testes and used for miRNAseq. Bioinformatic analysis identified 7 miRNA as differentially expressed between the HI and MOD treatment groups, with target mRNA genes invovled in pathways related to AMPK and IGF-1 signaling.
