Redheaded women respond better to painkilling drug

A gene associated with red hair and fair skin may also be responsible for how females respond to painkillers, according to a study conducted by lead researcher Jeffrey Mogil, a McGill University psychology professor, and collaborators in the United States. Results of their study are to be released today in Proceedings of the National Academy of Sciences of the USA (article #03-0053). “While we believe pain is the same in all women of all hair colours,” explained Mogil, “our study shows women with red hair respond better to the pain-killing drug we tested than anyone else — including men.”

Normal nerve cells can mimic viruses

A Montreal researcher has discovered that nerve cells can bypass the body’s normal protein-making machinery in the same way that viruses do when they infect a cell. Why would they? To produce large quantities of a particular protein under certain physiological conditions.

Team uses genomic tools to discover gene for childhood genetic disorder

In an advance illustrating the power of genomic information, an international team of researchers today announced it has identified a gene that causes Leigh Syndrome, French Canadian type (LSFC), a fatal inherited disorder affecting 1 in 2000 live births each year in the Saguenay-Lac St Jean region of Quebec. The paper appears in the January 14 issue of the journal Proceedings of the National Academy of Sciences. The findings will have immediate clinical implications for families in the Saguenay-Lac St-Jean region in the Quebec province in Canada, where the disorder is common and is associated with high infant and childhood mortality.
