Sentences with phrase «of epigenetic tag»

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.

These new genes were created so they could not be the repositories of epigenetic tags or modifications.

Not exact matches

Specifically, the study reveals a mechanism that helps explain how dividing cells pass patterns of epigenetic information called methyl tags to their daughter cells, a crucial part of regulating gene expression across cell generations.

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.

DNA methylation, or the addition of methyl tags to DNA, is one of the most well - studied epigenetic signals; errors in this process are commonly found in cancer.

However, in some studies with laboratory mice, Feinberg had observed that these epigenetic tags varied considerably among the mice even when comparing the same type of tissue in animals that have been living in the exact same conditions.

For a plant to create reproductive cells, it must first erase a key code, a series of tags attached to DNA across the genome known as epigenetic marks.

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

There are more than 100 varieties of these chemical tags, collectively known as epigenetic marks.

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.

It's the first time anyone has identified changes in these chemical tags — known as epigenetic changes — in the sperm of obese men, he says.

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.

Using data from blood and brain tissue, a team led by researchers at Johns Hopkins Bloomberg School of Public Health found that they could gain insights into mechanisms that might help explain autism by analyzing the interplay between genes and chemical tags that control whether genes are used to make a protein, called epigenetic marks.

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.

Sirt1 study helps demystify the role of diet in health and aging 2013 November 22 Tags: Epigenetics, Metabolism, Personal Care

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.
