Imprinting in Medical News

Not just humans benefit from animal biotechnology

... effective when one of the copies is already silenced, as happens in the phenomenon known as genomic imprinting. Sang cited the case of sheep, where imprinting of a gene called callipyge leads to increased muscle growth in the hindquarters, which clearly can be a desirable trait in meat production. All ...

New research explores newborn in-hospital weight loss

... first few days, loss of 5-7% of birth weight is considered physiologically appropriate. Newborn feeding experiences may be critical in metabolic imprinting and may factor into adult weight. The most influential predictor of weight loss in newborns is the type of infant feeding, conclude the authors. ...

'single–parent' stem cells to replace adult mice organ

... imprinting, where cells will read certain genes from only one parent. imprinting failures could lead to the death of an embryo and are frequently ... of genomic imprinting," McLaughlin said. "It turns out that genomic imprinting may be more a concern for developing stages and not so much a factor in ...

Women Choose Their Men With Their Fathers Resemblance

... of a parents role in this process, which until recently researchers believed to be a passive one. It adds to growing theories that suggest sexual imprinting is an active process which involves the relationship between the child and the adult upon whom they imprint. This reveals the importance of ...

New Hope for Regenerative Medicine

... hurdle of genomic imprinting, in which specific gene expression patterns are dictated by the parental origin. Uniparental cells only have the imprinting marks for one parental type (or "from one parent") with unknown consequences if harvested and transplanted into adults. Previous work has ...

Mothers’ diet during pregnancy may cause child obesit

... obesity. At the moment every stage of the cycle is wrong and needs looking at. Until that happens it is like a vicious circle where a mother is imprinting her baby with a faulty metabolism which is passed on in the genes and just keeps on being passed on." It would certainly do a world of good if ...

High-Protein Diet Found To Reduce Fertility

... embryo implantation in the womb and development of the fetus. They found that a diet consisting of 25 percent protein disrupted normal gene imprinting patterns in mice embryos at an early stage in their development. Some mice were fed a diet containing 25 percent protein. The control group was fed ...
