Epigenetic consequences of artificial reproductive technologies to the bovine imprinted genes SNRPN, H19/IGF2, and IGF2R
Animal breeders have made widespread use of assisted reproductive technologies to accelerate genetic improvement programs aimed at obtaining more, better and cheaper food products. Selection approaches have traditionally focused on Mendel's laws of inheritance using parental phenotypic characteristics and quantitative genetics approaches to choose the best parents for the next generation, regar...
متن کاملUnregulated expression of the imprinted genes H19 and Igf2r in mouse uniparental fetuses.
The present study shows that the H19 and Igf2r genes, which are imprinted and expressed solely from maternal alleles, are expressed in an unregulatable manner in mouse uniparental, androgenetic, and parthenogenetic fetuses at day 9.5 of gestation. In the androgenetic fetuses, the H19 and Igf2r genes were respectively expressed at 12 and 40% of the levels in biparental fetuses. In addition, the ...
متن کاملBidirectional action of the Igf2r imprint control element on upstream and downstream imprinted genes.
Imprinting of the maternally-expressed Igf2r gene is controlled by an intronic imprint control element (ICE) known as Region2 that contains the promoter of the noncoding Air RNA, whose transcript overlaps the silenced paternal Igf2r promoter in an antisense orientation. Two novel imprinted genes, Slc22a2 and Slc22a3 are described here that lie 110 and 155 kb 3' to Igf2r and that are not overlap...
متن کاملCorrelation of expression and methylation of imprinted genes with pluripotency of parthenogenetic embryonic stem cells.
Mammalian parthenogenetic embryos (pE) are not viable due to placental deficiency, presumably resulting from lack of paternally expressed imprinted genes. Pluripotent parthenogenetic embryonic stem (pES) cells derived from pE could advance regenerative medicine by avoiding immuno-rejection and ethical roadblocks. We attempted to explore the epigenetic status of imprinted genes in the generation...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
