TranscriptomicsEffects of pregnancy and progesterone supplementation on endometrial gene expression in cattle
An increase in circulating progesterone (P4) concentrations is associated with increased pregnancy success in beef and dairy cattle. Our objective was to ascertain differential effects of elevated P4 concentrations following conception on endometrial gene expression in beef heifers on Days 5, 7, 13 ...

TranscriptomicsSex-related transcriptional differences in Day 7 bovine in vitro produced blastocysts
Sexual dimorphism in mammals is mostly attributable to sex-related hormonal differences in fetal and adult tissues; however, this may not be the sole determinant. Though genetically-identical for autosomal chromosomes, male and female preimplantation embryos could display sex-specific transcriptiona...

TranscriptomicsGene Expression Profiles in Immature and In vitro matured bovine Oocytes
In cattle, almost all fully grown vesicle stage oocytes (GV) have the ability to resume meisos, develop to Metaphase II stage (MII), support fertilization and progress through the early embryonic cycles in vitro. Yet without intensive selection, the majority fail to develop to the blastocyst stage. ...

TranscriptomicsOviduct-Embryo Interactions in Cattle: Two-Way Traffic or a One-Way Street? [Affymetrix]
The objective of this study was to examine the effect of the presence of a single or multiple embryo(s) on the transcriptome of the bovine oviduct. In Experiment 1, cyclic (non-bred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampull...

ProteomicsProtein Profile of Bovine Oviductal Extracellular Vesicles
The study of early maternal-embryonic cross-talk remains one of the most challenging topics in reproductive biology. Understanding the physiological mechanisms involved in the interactions between the maternal reproductive tract and the developing embryo is essential for enhancing bovine reproductiv...
