A journey through horse cloning
(Csiro Publishing, 2017-12)
Interest in equine somatic cell nuclear transfer technology has increased significantly since the first equid clones were produced in 2003. This is demonstrated by the multiple commercial equine cloning companies having ...
Equine cloning: In vitro and In vivo development of aggregated embryos
(Society For The Study Of Reproduction, 2012-07)
The production of cloned equine embryos remains highly inefficient. Embryo aggregation has not yet been tested in the equine, and it might represent an interesting strategy to improve embryo development. This study evaluated ...
Targeting epigenetic nuclear reprogramming in aggregated cloned equine embryos
(Csiro Publishing, 2019-10)
Epigenetic perturbations during the reprogramming process have been described as the primary cause of the low efficiency of somatic cell nuclear transfer (SCNT). In this study, we tested three strategies targeting nuclear ...
The aggregation of four reconstructed zygotes is the limit to improve the developmental competence of cloned equine embryos
(Public Library Of Science, 2014-11)
Embryo aggregation has been demonstrated to improve cloning efficiency in mammals. However, since no more than three embryos have been used for aggregation, the effect of using a larger number of cloned zygotes is unknown. ...
Cloning, sequencing and expression analysis of the equine hepcidin gene by real-time PCR
(Elsevier B.V., 2010-05-15)
Equine serum or plasma iron concentration drops quickly during inflammation. Accumulation of iron inside macrophages and reduction of the intestinal absorption of this element cause hypoferremia during systemic inflammatory ...

Paternity test in "mangalarga-marchador" equines by DNA-fingerprinting.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.35, n.10, p.2007-15, out.2000., 2011)
Artificial activation of bovine and equine oocytes with cycloheximide, roscovitine, strontium, or 6-dimethylaminopurine in low or high calcium concentrations
(Cambridge University Press, 2014-08-01)
Knowledge on parthenogenetic activation of oocytes is important to improve the efficiency of nuclear transfer (NT) and intracytoplasmic sperm injection (ICSI) because artificial activation of oocyte (AOA) is an essential ...
Cloning, sequencing and expression analysis of the equine hepcidin gene by real-time PCR
(Elsevier B.V., 2014)
Molecular cloning and characterization of Phospholipase C Zeta in equine sperm and testis reveals species-specific differences in expression of catalytically active protein
(Society For The Study Of Reproduction, 2011-07)
Oocyte activation at fertilization is brought about by the testis-specific phospholipase C zeta (PLCZ), owing to its ability to induce oscillations in intracellular Ca(2+) concentration ([Ca(2+)](i)). Whereas this is a ...
