Sentences with phrase «epigenetic tags on»

Feinberg, Fallin and their team assessed the epigenetic tags on DNA from sperm from 44 dads.

The test, based on epigenetic tags on the genome, claims 67 per cent accuracy, but concerns over eugenics and misuse have led lead researcher to quit his job

Not exact matches

The findings center on a protein called UHRF1, a guardian of the cell's epigenetic information that can recognize patterns of epigenetic tags and promote the addition of new ones.

Epigenetic tags help tell genes — stretches of DNA that act as biological instruction manuals — when to switch «on» and «off,» ultimately determining cell type and function.

On the outside of the heterochromatin bundles are chemical markers, known as epigenetic tags, which control the structure of the heterochromatin.

Most research on epigenetics has focused on the way everyday experiences alter patterns of gene activity in DNA during life through a chemical process of gene tagging called methylation, which usually silences genes.

Before now, a lot of this epigenetic research had been done in yeast — single cell organisms that also use enzymes to lay chemical tags on histone proteins.

DNA methylation, one mechanism of epigenetics, is a chemical tag on DNA that does not change the gene sequence but is involved in controlling gene expression.

Much of the previous research on epigenetics has focused on the fact that everyday experiences alter patterns of gene activity in DNA during life through a chemical process of gene tagging called methylation, which usually silences genes.

Compared with people who had never smoked, these individuals had fewer chemical tags known as methyl groups — a common type of epigenetic change — on 20 different regions of their DNA.

Researchers working at the National Agriculture and Food Research Organization in Japan have found that epigenetic tags, such as methyl groups, on some areas of the plant genome can cause interference with gene editors and reduce their efficiency.

His lab specializes in epigenetics — analyzing the chemical tags on genes that influence their activity.

Gontier and colleagues found that as mice age, Tet2 levels in the hippocampus decline, as do the epigenetic tags Tet2 makes on DNA.

The researchers then analyzed the DNA to examine the degree of an epigenetic mark called methylation, a chemical tag on genes related to whether they're «turned on» or «off.»

Tinkering with gene switches can have a profound effect on how they behave, and labs around the world are now scanning the genome in hopes of identifying epigenetic modifications — sometimes called «marks» or «tags» — that could serve as biomarkers, helping to predict and identify a wide range of conditions.
