Honey, I shrunk the ants: how environment controls size

Ground breaking epigenetics research has implications for everything from cancer to farming

McGill scientist shrink ants

Until now scientists have believed that the variations in traits such as our height, skin colour, tendency to gain weight or not, intelligence, tendency to develop certain diseases, etc., all of them traits that exist along a continuum, were a result of both genetic and environmental factors. But they didn’t know how exactly these things worked together. By studying ants, McGill researchers have identified a key mechanism by which environmental (or epigenetic) factors influence the expression of all of these traits, (along with many more).

Brain development controlled by epigenetic factor

Research into hippocampus has implications for learning and memory
Tue, 2015-03-10 15:30

McGill researchers have discovered, for the first time, the importance of a key epigenetic regulator in the development of the hippocampus, a part of the brain associated with learning, memory and neural stem cells. Epigenetic regulators change the way specific genes function without altering their DNA sequence. By working with mutant mice as models, the research team, led by Prof. Xiang-Jiao Yang, of McGill’s Goodman Cancer Center & Department of Medicine, McGill University Health Center, was able to link the importance of a specific epigenetic regulator known as BRPF1 to the healthy development of a region in the hippocampus called the dentate gyrus.

Popular antioxidant likely ineffective, study finds

Research with mice undercuts widely held belief that ubiquinone protects cells against damage from free radicals
Fri, 2015-03-06 09:56

The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study by scientists at McGill University finds that ubiquinone is not a crucial antioxidant -- and that consuming it is unlikely to provide any benefit.

Most information in drug development is lost

Mon, 2015-03-09 10:41

Lots of potentially useful medical information is getting lost. McGill researchers discovered this when they looked into the lack of reporting of information from “stalled drug” trials in cancer, cardiovascular and neurological diseases.

Chairs in social pediatrics to be established

The Montreal Children’s Hospital Foundation, McGill University, the Université de Montréal and the Fondation du Dr Julien announce the creation of two chairs in social pediatrics in the community
Thu, 2015-02-26 13:29

The Montreal Children’s Hospital Foundation, McGill University, the Université de Montréal and the Fondation du Dr Julien will establish two chairs in social pediatrics in the community, to be based in the Montreal neighbourhood of Hochelaga-Maisonneuve. In a Canadian first, researchers will conduct a long-term study on social pediatrics in the community.  This clinical practice has a proven track record, thanks to its founder, Dr. Gilles Julien, who has been practicing social pediatrics in disadvantaged neighbourhoods for nearly 30 years.
