• Abstract

  In bovine herds the early embryonic mortality, caused by failures in maternal fetal recognition between days 15 and 19 after fertilization, is one of the major causes of reproductive failures. Strategies that may favor maternal fetal recognition during such a critical period become of fundamental economic interest. Such strategies aim to reduce the ability of PGF2 alpha synthesis by the m…

  Effect of supplementation with conjugated linoleic acid in culture of trophoblastic cells and in vitro production of bovine embryos on synthesis of prostaglandin E2 and F2α and expression of transcripts involved in eicosanoid biosynthesis and establishment, BP.PD

• Abstract

  DNA methylation is an important epigenetic modification in many cellular processes, playing an important role as regulator of gene expression. Recent studies show the broad association between methylation levels and gene expression variation. However, the association between genetic variation and DNA methylation, as well as the genetic determinants of DNA methylation patterns are still un…

• Abstract

  During the duration of the scholarship grantee conducted a study with a student undergraduates which suggests that it be used as in Experiment 1 development of the Master's thesis of the same, since the model used supplementation effectively increases rates conception. This study aimed to compare conception rates at 30 days of gestation in embryo recipients undergoing Embryo Transfer in F…

• Abstract

  Early embryonic mortality, caused by failures in maternal-fetal recognition in the first three weeks after fertilization represents a major cause of reproductive inefficiency in the cattle industry. During this pre-implantation period, the conceptus (embryo and its associated extra-embryonic membranes) present in the uterine lumen must secrete molecules, such as interferon-tau (IFNT), tha…

• Abstract

  Manifestation of cellular phenotypes and regulation of complex biological processes require transcriptional regulation of genes. Alteration of the interaction between chromatin components results in the deregulation of cellular transcriptional program, demonstrating that the chromatin plays a dynamic role in the transcriptional processes. However, the access of various transcriptional fac…
