No way to know. At a minimum need a centrifuge to look at weightlessness while holding everything else constant.

The problem with this is the controls. Was the liver damage due to weightlessness? radiation? Something in the ISS atmosphere? Stress of launch and re-entry?

We need to look at mice involved in longer duration space flight to see if there are compensatory mechanisms that come into play that might protect them from serious damage, Jonscher said.
