Mice Stressed In Simulated Weightlessness Show Organ Atrophy
New Brunswick NJ (SPX) Sep 04, 2007 - A ground-based, experimental model used to simulate astronaut weightlessness in space has provided Rutgers scientists an opportunity to study the effects of stress on immune organs. Earlier collaborative research with Japanese scientists employing this model implicated the protein osteopontin (OPN) in bone mineral loss associated with simulated weightlessness in mice. This research was made possible by the creation at Rutgers of a mouse unable to make OPN (a knock-out mouse).
