Genes related to self-control could be 'disabled' by the prenatal environment Chronic aggressive behavior exhibited by some boys from disadvantaged families may be due to epigenetic changes during pregnancy and early childhood. This is highlighted by two studies conducted by a team led by Richard E. Tremblay, professor emeritus at the University of Montreal and Moshe Szyf, professor at McGill University, published in the journal PLOS ONE. The first author of the two papers, Nadine...

Microbes that live in rice paddies, northern peat bogs and other previously unexpected environments are among the bacteria that can generate highly toxic methylmercury, researchers at Oak Ridge National Laboratory and the Smithsonian Environmental Research Center have learned. This finding, published in Environmental Science and Technology, explains why deadly methylated mercury is produced in areas where the neurotoxin’s presence has puzzled researchers for decades. Methylmercury —...

Even before they are born, babies accumulate changes in their DNA through a process called DNA methylation that may interfere with gene expression, and in turn, their health as they grow up. But until now it's been unclear just how long these changes during the prenatal period persist. In a new study, researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health establish that signs of DNA methylation persist through early childhood, suggesting...

Stowers investigators show that rules governing expression of developmental genes in mouse embryonic stem cells are more nuanced than anticipated A decade ago, gene expression seemed so straightforward: genes were either switched on or off. Not both. Then in 2006, a blockbuster finding reported that developmentally regulated genes in mouse embryonic stem cells can have marks associated with both active and repressed genes, and that such genes, which were referred to as "bivalently marked...

UBC researchers discover unusual key to regulating cell growth Researchers at the University of British Columbia have discovered a potential new pathway to treat cancer by asking some odd questions about the size of animals. "Mammals display a huge range in size from the largest blue whale to the tiniest fruit bat," says Colby Zaph, assistant professor of Pathology and Laboratory Medicine at the Biomedical Research Centre, who co-authored the study published in Developmental Cell....

Brain Epigenome Changes Through Developmental Years

Brett Smith for redOrbit.com - Your Universe Online While the entire genome has been sequenced and the codes of many genes have been identified, there are is a wide range of unknown mechanisms that interact with the code without changing "letters" of the DNA. These chemical changes to DNA are referred to as the epigenome, and a new study in the journal Science has revealed significant epigenomic activity during brain development. DNA includes four chemical bases: adenine (A), guanine...

Methylation refers to a chemical modification of DNA and this modification can occur in millions of positions in the DNA sequence. Until now, scientists believed that this epigenetic phenomenon actively reduced the expression of certain genes. Today, a team of researchers from the University of Geneva (UNIGE), Switzerland, led by Emmanouil Dermitzakis, Louis-Jeantet Professor at the Faculty of Medicine, reveals that this is not always the case and that DNA methylation may play both a passive...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
