Genes Regulating Maternal Recognition of Pregnancy in Domestic Animals: an Update

Abstract: Early embryonic mortality is one of the main sources of reproductive wastages and major constraints for full exploitation of the production potential of livestock. The survivality of embryo during early embryonic life is mostly dependent on the efficiency with which the maternal recognition of pregnancy (MRP) is established. Maternal recognition of pregnancy involves molecular dialogue between the trophoblast of conceptus and uterine endometrium. Embryonic development to the blastocyst stage and uterine differ… Show more

“…The KEGG protein processing in the Mitogen-Activated Protein Kinase (MAPK) signaling pathway is involved in a conserved module that controls various cellular events and biological processes, such as embryogenesis, cell differentiation, cell proliferation, cell death, short-term changes required for homeostasis, and acute hormonal responses [79][80][81]. Also, this pathway is associated with preimplantation embryogenesis [82], defined as the time interval from conception to nidation or attachment of the embryo to the uterus, a crucial stage in successful pregnancies related to embryonic health, and therefore reproductive efficiency [83].…”

“…Reportes indican que; -existe un incremento en los niveles basales de LH después de cópulas posovulatoria (Aba et al, 1995) y -que la aplicación de LH en los días D1 y D3,5 posovulación redujeron en un porcentaje razonable el celo posovulatorio entre los días D2 y D4 (Fernández, 2013). Estas informaciones indicarían que, en el empadre a campo, el efecto acumulativo de las cópulas continuas (por ende, el β-NGF), deben estar relacionadas con la mantención de un elevado nivel basal de LH, para que el cuerpo lúteo se establezca produciendo el nivel apropiado de progesterona para inhibir el celo y continuar con la función de mantención de la gestación; en caso contrario los niveles crecientes de E2 indirectamente mediarían la secreción de PGF2α, afectando la viabilidad del Cuerpo lúteo (Leyva y García, 2000), ocasionando una muerte embrionaria temprana, puesto que la sobrevivencia del embrión en este periodo, depende principalmente de la eficiencia con la que se establece el reconocimiento materno de la preñez (Mor et al, 2015). Lo anterior está mediado por el útero, que por la estructura y organización de la matriz extracelular y mecanismos de adhesión celular afecta en la sobrevivencia del embrión durante el período de implantación después de la preñez (Moraes et al, 2018).…”

“…Entonces estos factores que tienen que ver con la mortalidad temprana no están del todo claros por lo que deberán ser demostrados en otras investigaciones. Es importante considerar la identificación de genes en alpacas como se ve en otras especies, genes que estén asociados a este evento de transición y la definición de su significado funcional podrían proporcionar información vital para identificar las razones por la que no se da el reconocimiento materno de la preñez (Mor et al, 2015).…”

“…İmplantasyonda etkili moleküllerden önemli bir tanesi olan Prostaglandinler (PG) hücre çoğalması, farklılaşması ve bağışıklık fonksiyonlarına ilaveten anjiogenezis ve damar tonusu gibi damar fizyolojik fonksiyonları da düzenlemektedir. Ayrıca PG'lerin üreme sürecinin düzenlenmesine ve gebeliğin başarılı bir biçimde şekillenmesine büyük katkı sağladığı bilinmektedir (Mondal, 2009;Mor, 2015). Araşidonik asitten prostaglandin sentezinde hız sınırlayıcı olarak işlev gören siklooksijenazların izoformlarından birisi olan COX-2'nin embriyonun gelişim sürecinde etkili olduğu bildirilmiştir (Wang, 2010).…”
