TranscriptomicsBovine trophoblasts: control vs. infected with Brucella abortus
Brucellosis is still a widespread zoonotic disease. Very little is known about the interaction between B. abortus and trophoblastic cells, which is essential for better understanding the pathogenesis of the Brucella-induced placentitis and abortion, a key event for transmission of the disease. The g...

TranscriptomicsMicroarray analysis of the oocyte quality
Microarray analysis was performed in ooplast samples to identify gene expression profiles associated with the embryo capacity to develop to blastocyst stage A fraction of the cytoplasm from in vitro matured oocytes was collected and snap frozen. The oocytes were chemically activated and presumptive ...

TranscriptomicsGenome-wide analysis of histone modification, protein-DNA binding, cytosine methylation and transcriptome data in mouse and human ES cells and pig iPS cells
Genome-wide analysis of histone modification (H2AZ, H3K27ac, H3K27me3, H3K36me3, H3K4me1, H3K4me2, H3K4me3 and H3K9me3), protein-DNA binding (TAF1, P300, Pou5f1 and Nanog), cytosine methylation and transcriptome data in mouse and human ES cells and pig iPS cells We generated histone modification da...

TranscriptomicsThe effect of negative energy balance on bovine blood PMN gene expression
Our objectives were to compare gene expression profiles in neutrophils (PMN) during a Streptococcus uberis mastitis challenge between lactating cows subjected to feed restriction to induce negative energy balance (NEB; n = 5) and cows fed ad libitum to maintain positive energy balance (PEB; n = 5). ...

TranscriptomicsGene Expression Profiling of Single Embryos, Significant Effects of In Vitro Maturation, Fertilization and Culture
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...

TranscriptomicsBovine Peyer's Patch Infected with Mycobacterium avium ssp. paratuberculosis and Mycobacterium avium ssp. avium
Mycobacterium avium subspecies paratuberculosis (MAP) infection is established following the ingestion of bacteria, their penetration of the intestinal mucosa and subsequent events of the host-parasite interaction. These bacteria invade M cells, macrophages and are capable of resisting host defenses...

TranscriptomicsTemporal gene expression analysis of the Brucella melitensis-infected bovine Peyer's patch
In a time course study, we characterized global gene expression profile of B. melitensis-infected bovine Peyer patches in the first 4 h p.i. Microarray analysis revealed that 2,916 bovine genes were detected as differentially expressed (z-score p < 0.025) in loops inoculated with virulent B. meliten...

TranscriptomicsAI versus IVF-ET & AI versus SCNT
Implantation is crucial for placental development which directly impacts fetal growth and pregnancy success with possible consequences on post-natal health. We postulated that early perturbations of the conceptus-maternal environment communication may alter the endometrium physiology that could acco...

TranscriptomicsComparison between caruncles and intercaruncles in AI, IVF-ET and SCNT pregnancies
Implantation is crucial for placental development whose quality will directly impact fetal growth and pregnancy success with possible consequences on post-natal health. We postulated that early perturbations of the conceptus-maternal environment communication may alter the endometrium physiology tha...

TranscriptomicsThe bovine mammary transcriptome: functional adaptation of the mammary gland during the lactation cycle
Bovine mammary gland provide the largest amount of milk for dairy industry to date. Insight in functional adaptation of this organ is critical in order to improve efficiency of milk synthesis and milk quality. In the present experiment microarray analysis in combination with bioinformatics tools was...
