Imprinting and Promoter Usage of Insulin-Like Growth Factor II in Twin Discordant Placenta

Obstetrics and Gynecology International, 2010
Case reports from infant twins suggest that abnormal genomic imprinting may be one of the important causes of twin discordance, but it is unknown whether abnormal genomic imprinting occurs in the placenta.

Parent-of-origin effects cause genetic variation in pig performance traits [PDF]

, 2017
In order to assess the relative importance of genomic imprinting for the genetic variation of traits economically relevant for pork production, a data set containing 21 209 records from Large White pigs was analysed.

Future trends in Animal Breeding due to new genetic tecnologies

, 2011
The Darwin theory of evolution by natural selection is based on three principles: (a) variation; (b) inheritance; and (c) natural selection. Here, I take these principles as an excuse to review some topics related to the future research prospects in ...

Cell-cell communication-mediated cell-type-specific parent-of-origin effects in mammals

Nature Communications
Genomic imprinting is manifested as monoallelic expression of genes according to parental origin, which is closely linked to mammalian placentation and human diseases. Yet, it is unclear how genomic imprinting evolves in different cell types.

The evolution of the DLK1-DIO3 imprinted domain in mammals.

PLoS Biology, 2008
A comprehensive, domain-wide comparative analysis of genomic imprinting between mammals that imprint and those that do not can provide valuable information about how and why imprinting evolved.

Transcriptome-wide identification and characterization of genes exhibit allele-specific imprinting in maize embryo and endosperm

BMC Plant Biology, 2023
Background Genomic imprinting refers to a subset of genes that are expressed from only one parental allele during seed development in plants. Studies on genomic imprinting have revealed that intraspecific variations in genomic imprinting expression exist

Internuclear gene silencing in Phytophthora infestans is established through chromatin remodelling [PDF]

, 2008
In the plant pathogen Phytophthora infestans, nuclear integration of inf1 transgenic DNA sequences results in internuclear gene silencing of inf1. Although silencing is regulated at the transcriptional level, it also affects transcription from other ...

Copy number rather than epigenetic alterations are the major dictator of imprinted methylation in tumors

Nature Communications, 2017
Altered genomic imprinting is frequently reported in cancer. Here, the authors analyze copy number and methylation in cancer cell lines and primary tumors to show that imprinted methylation profiles represent the accumulation of copy number alteration ...

Theory of genomic imprinting conflict in social insects

BMC Evolutionary Biology, 2003
Background Genomic imprinting refers to the differential expression of genes inherited from the mother and father (matrigenes and patrigenes). The kinship theory of genomic imprinting treats parent-specific gene expression as products of within-genome ...
