McGill, Quebec biotech firm partner for new bone-disease treatment

Dr. Marc McKee, of McGill's Faculty of Dentistry and the Department of Anatomy and Cell Biology, is collaborating closely with Enobia Pharma Inc, a Quebec biotech company, to develop innovative treatments for serious genetic bone diseases. McKee's research looks into the reasons why calcium-phosphate mineral fails to crystallize properly to form strong bones and teeth. While osteoporosis later in life is an example of bone density deficiency, this research applies to patients, especially children, who never properly mineralized their skeletons to begin with. The field is known as biomineralization and it involves cutting-edge, nanotech investigation into the proteins, enzymes and other molecules that control the coupling of mineral ions (calcium and phosphate) to form nano-crystals within the bone structure. The treatment, enzyme replacement therapy to treat hypophosphatasia, is currently undergoing clinical testing in several countries including Canada. Hypophosphatasia is a rare and severe disorder resulting in poor bone mineralization. In infants, symptoms include respiratory insufficiency, failure to thrive and rickets.
