Project description:The objective of this study was to compare liver gene expressions in bovine fetuses derived from somatic cell nuclear transplantion (NT) with those in the liver of bovine fetuses derived from artificial insemination (AI) and in vitro fertilized (IVF) eggs. Gene expression profiles in the liver of an NT-calf was also compared with those in the liver of AI-calf.

Project description:This study aimed to identify bovine conceptus-induced modifications to the endometrial transcriptome both dependent and independent of interferon tau (IFNT), dependent on conceptus origin [in vitro fertilization (IVF) or artifical insemination (AI) derived blastocysts] and dependent on conceptus sex. Major findings include identification of genes differentially expressed in endometrium in response to the conceptus but independent of IFNT and genes differentially expressed in endometrium in response to AI vs. IVF and male vs. female conceptuses.

Project description:In vitro production (IVP) has been shown to affect embryonic gene expression and often result in large offspring syndrome (LOS) in cattle and sheep. To dissect the effects of in vitro maturation, fertilization and culture, we compared the expression profiles of single bovine blastocysts generated by: 1) in vitro maturation, fertilization and culture (IVF); 2) in vivo maturation, fertilization and in vitro culture (IVD); and 3) in vivo maturation, fertilization and development (AI). To conduct expression profiling, total RNA was isolated from individual embryos, linearly amplified and hybridized to a custom bovine cDNA microarray containing approximately 6,300 unique genes. There were 306, 367 and 200 genes differentially expressed between the AI and IVD, IVF and IVD and AI and IVF comparisons, respectively. Interestingly, 44 differentially expressed genes were identified between the AI embryos and both the IVF and IVD embryos, making these potential candidates for LOS. There were 60 genes differentially expressed between the IVF embryos and the AI and IVD embryos. The Gene Ontology category M-bM-^@M-^\RNA processingM-bM-^@M-^] was over-represented among the genes that were down-regulated in the IVF embryos, indicating an effect of in vitro oocyte maturation/fertilization on embryonic gene expression. A culture effect on the expression of genes involved in translation was also observed by the comparison of AI to IVD embryos. Reference design with dye swap. 43 individual embryos were analyzed.

There were 60 genes differentially expressed between the IVF embryos and the AI and IVD embryos. The Gene Ontology category “RNA processing” was over-represented among the genes that were down-regulated in the IVF embryos, indicating an effect of in vitro oocyte maturation/fertilization on embryonic gene expression. A culture effect on the expression of genes involved in translation was also observed by the comparison of AI to IVD embryos. Keywords: developmental condition

Project description:In vitro maturation (IVM) of the oocytes is a routine method in bovine embryo production. The competence of bovine oocytes to develop into embryo after IVM and in vitro fertilization (IVF) is lower as compared to in vivo preovulatory oocytes. Cumulus cells (CC) that enclose an oocyte are involved in the acquisition of oocyte quality during maturation. Using transcriptomic approach we compared cumulus cells gene expression during IVM with that in vivo preovulatory period.
