McGill research team finds distinct disease-causing mutations and saves baby girl

About two years ago, Dr. Philippe Gros, a McGill University professor in the Department of Biochemistry and a Principal Investigator in thd McGill Life Sciences Complex, described a mouse mutant that was immunodeficient and hypersensitive to the Bacille Calmette-Gu-rin (BCG) vaccine and to tuberculosis (TB).

$100,000 needed to analyze '$1,000' genetic data

Advances in technology have almost lifted the curtain on the long-awaited era of the "$1,000 genome" - a time when all the genes that make up a person can be deciphered for about that amount - compared to nearly $1 million a few years ago.

Researchers help explain why smart drugs are not effective in some cancer patients

Some of the most effective and expensive cancer drugs, dubbed "smart drugs" for their ability to stop tumors by targeting key drivers of cancer cell growth, are not effective in some patients. In two related studies, Yale School of Medicine researchers examined one such driver, the EGF receptor, and found that a decoy receptor might be limiting the amount of drug that gets to the intended target.

Noninvasive stool test can detect pancreatic cancer

Pancreatic cancer has one of the highest mortality rates of any of the major cancers, and of the 43,000-plus Americans diagnosed with the disease each year, more than 94 percent die within five years of diagnosis. One reason for this high number of deaths is a lack of effective screening tools for catching the disease early.

Losartan therapy improves muscle injury regeneration and prevents disuse atrophy

Using geriatric mice, a Johns Hopkins research team has shown that losartan, a commonly used blood pressure drug, not only improves regeneration of injured muscle but also protects against its wasting away from inactivity.

Research shows that cold cognition predicts hot emotion

How useful would it be to anticipate how well someone will control their emotions? To predict how well they might be able to stay calm during stress? To accept critical feedback stoically? Heath A. Demaree, professor of psychology at Case Western Reserve University, finds clues in what psychologists call "hot" and "cold" psychology.

New research may help explain how post-traumatic stress syndrome develops in some people

Adversity, we are told, heightens our senses, imprinting sights and sounds precisely in our memories. But new Weizmann Institute research, which appeared in Nature Neuroscience this week, suggests the exact opposite may be the case: Perceptions learned in an aversive context are not as sharp as those learned in other circumstances.

Salmonella enterica bacterium activates virulence genes through Fur protein

Salmonella enterica, one of the main causes of gastrointestinal infections, modulates its virulence gene expression, adapting it to each stage of the infection process, depending on the free iron concentration found in the intestinal epithelium of its host.
