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.
