EAST LANSING, Mich. — A mouse created by Michigan State University scientists studying a disease thought to be a neurological disorder that weakens men has exposed two surprises: Testosterone appears to be the culprit and it’s attacking muscles, not nerves. The muscles of male mice genetically engineered in the laboratory of Cynthia Jordan, professor of neuroscience and psychology, have extra receptors that latch onto testosterone – a trick that left researchers anticipating mouse versions of bulked up body builders. Instead, these mice developed into shrunken weaklings. More significantly, their condition precisely imitated a rare human condition called Kennedy’s Disease.
