Methods Embryo transfer … Witryna1 wrz 2001 · Genetics. Biotechnology. Cloning using nuclear transfer technology is an inefficient process in which most clones die before birth and survivors often display growth abnormalities. This is attributed to genetic imprinting – particular genes in the donor nucleus are permanently turned on or off. Imprinting appears to vary between …

WitrynaGenomic imprinting is the phenomenon where the expression of a locus differs between the maternally and paternally inherited alleles. Typically, this manifests as transcriptional silencing of one of the alleles, although many genes are imprinted in a tissue- or isoform-specific manner.

"Witryna1 wrz 2004 · The PatDp(prox11) imprinting effect potentially attributable to Grb10 appears to operate primarily upon early fetal development, as previously suggested (Cattanach et al. 1992). The MatDp(prox7) imprinting effect appears to operate primarily upon the placenta, as might be expected if Peg3 is the responsible gene. " - Imprinting in genetics

Witryna1 sty 2007 · In a classic article published in Genetics ( Crouse 1960b ), Helen coined the term “chromosome imprinting” when she wrote: “the ‘imprint’ a chromosome bears is unrelated to the genic constitution of the chromosome and is determined only by the sex of the germ line through which the chromosome has been inherited.”

WitrynaImprinted genes mediate fetal and childhood growth and development, and early growth patterns drive fetal programming effects. However, predictions and evidence from the kinship theory of imprinting have yet to be directly integrated with data on fetal programming and risks of metabolic disease.
