Medical Proteome Analysis of Osteoporosis and Bone Mass-related Proteins using the Kibo Japanese Experiment Module of International Space Station (Medical_Proteomics)
Principal Investigator
Research Area:
Bone Loss Team
Species Studied
Scientific Name: Homo sapiens Species: Human

Investigators aim to study changes in blood proteins of astronauts before and after space flight by using the latest proteome analysis technique, and identify the causal protein of osteopenia. If protein changes due to osteopenia in space is understood, it is possible to clarify not only the cause of the osteopenia, but also the proteins that cause osteoporosis on the ground. This research will provide the knowledge in order to maintain astronauts’ health, as well as results to contribute to disease countermeasures on the ground.
