Project description:Endometrial remodeling is required for implantation in all mammalian species. To identify the factors that promote cell proliferation at the implantation site were explored in bovine endometrium and extra-embryonic membrane during the peri-implantation period. Microarray analysis showed that the expression levels of various trophoblast specific genes were higher in the extra-embryonic membrane at gravid horn than in the extra-embryonic membrane at non-gravid horn namely, CSH1, PRPs, PAGs, AIF, Muc-1, etc. Furthermore, EGFR, INHBA and INHBB expression were higher in endometrium of gravid horn.

Gene expression profiles were analyzed in the gravid and non-gravid extra-embryonic membrane and endometrium at around Day 30 of gestation

Project description:During mammalian pre-implantation embryonic development dramatic and orchestrated changes occur in gene transcription. The identification of the complete changes has not been possible until the development of the Next Generation Sequencing Technology. Here we report the first transcriptome dynamics of single matured bovine oocytes and all stages of pre-implantation embryos developed in vivo. Surprisingly, nearly half of the bovine genome, 11,488 to 12,729 genes involved in more than 100 pathways, is expressed in oocytes and early embryos. Despite the similarity in the total numbers of genes expressed across stages, the nature of the expressed genes is dramatically different. A total of 2,845 genes were differentially expressed among different stages, of which the largest change was observed between the 4- and 8-cell stages, demonstrating that the bovine embryonic genome activation occurs at this transition. Additionally, 774 genes were identified as only expressed/highly enriched in particular stages of development. Using weighted gene co-expression network analysis, we found 12 stage-specific modules of co-expressed genes that can be used to represent the corresponding stage of development. Furthermore, we identified conserved key members (or hub genes) of the bovine expressed gene networks. Their vast association with other embryonic genes suggests that they may have important regulatory roles in embryogenesis; yet, the majority of the hub genes are relatively unknown/under-studied in embryos. We also conducted the first embryonic expression profile comparison across three mammalian species, human, mouse and bovine, for which RNA-seq data are available. We found that the three species share more maternally deposited genes than embryonic genome activated genes. More importantly, there are more similarities in embryonic transcriptomes between bovine and humans than between humans and mice, demonstrating that bovine embryos are better models for human embryonic development. This study provides the first comprehensive examination for gene activities in bovine embryos and identified little-known potential master regulators of pre-implantation development.

Project description:miRNAs have been implicated in the regulation of milk protein synthesis and development of mammary gland. However, the function of miRNAs in regulating lactation is unclear. Therefore, the elucidation of miRNA expression profiles in MG provides a crucial entry into the understanding of the mechanisms of lactation initiation. Our present work is to examine miRNA expression profiles in bovine mammary gland, and to evaluate miRNAs function through the identification of differentially expressed miRNA between lactation and non-lactation mammary gland. Identification of novel miRNAs highlights the important function of low abundance and less conserved miRNAs. An interaction network of known miRNAs and their target genes around the lactation function was constructed to postulate the functional roles of miRNAs in mammary gland. This integrated analysis provides important information that will inspire further experimental investigations into the field of miRNAs and their targets during lactation.

Project description:A central determinant of pregnancy success is proper development of the conceptus (embryo/fetus and associated extraembryonic membranes including the placenta). Although the gross morphology and histology of the bovine placenta has been well studied, the cellular and molecular mechanisms regulating placenta development and trophoblast differentiation and function remain essentially undefined. Here single cell RNA-seq analysis was performed on the day 17 bovine conceptus and chorion of day 24, 30 and 50 conceptuses (n = 3-4 samples per day) using the 10X Genomics platform. Bioinformatic analyses identified cell types and their ontogeny including trophoblast, mesenchyme, and immune cells. Loss of IFNT-expressing trophoblast uninucleate cells (UNC) occurred between days 17 and 30, whereas binucleate cells (BNC), identified based on expression of placental lactogen (CSH2) and pregnancy-associated glycoproteins (PAGs) marker genes, first appeared on day 24. Several different types of UNC were present in day 24, 30 and 50 samples, but only one (day 24) or two types of BNC (days 30 and 50). Cell trajectory analyses provided a conceptual framework for UNC development and BNC differentiation, and upstream transcription factor binding enrichment analyses identified candidate transcription factors governing differentiation and function of the trophoblasts. The digital atlas of cell types in the developing bovine conceptus reported here serves as a resource to discover key genes and biological pathways regulating its development during the critical periods of implantation and placentation.
