Well, it seems, space is definitely not good for the liver of a mouse.

Lab mice that spent just two weeks in space returned to Earth with early signs of liver disease, scientists have found, raising concerns about how long-term spaceflight and future missions to Mars may affect the health of astronauts.
The mice spent 13.5 days aboard Nasa's space shuttle Atlantis. Researchers found that spaceflight appeared to activate specialised liver cells that may go on to induce scarring and cause long-term damage to the organ.
"The mice also lost lean muscle mass," said Karen Jonscher, from University of Colorado. "We have seen this phenomenon in humans on bedrest -muscle atrophy and proteins break down into amino acids," she said, pointing out that the stress of spaceflight and reentry to Earth might have also played a role in liver damage.
