ProteomicsUse of data-independent acquisition mass spectrometry to identify an objective serum indicator of the need for osteoporotic therapeutic intervention
Osteoporosis is characterized by weakened bone microstructure and loss of bone mass. Current diagnostic criteria for osteoporosis are based on the T-score, which is a measure of bone mineral density. However, osteoporotic fragility fractures can occur regardless of the T-score, underscoring the need...

ProteomicsComprehensive human serum spectral library
For a comprehensive analysis of the human serum proteome, we constructed a spectral library for DIA-MS. Our spectral library contained information on 20,303 peptides derived from 1,597 human serum proteins. We believe that the constructed spectral library will be useful for proteomic analysis of hum...

ProteomicsChanges in the astronaut serum proteome during prolonged spaceflight
The molecular mechanisms associated with spaceflight-induced biological adaptations that may affect many healthy tissue functions remain poorly understood. In this study, we analyzed temporal changes in the serum proteome of six astronauts during prolonged spaceflight missions using quantitative com...

ProteomicsIdentification of gravity-responsive serum proteins in spaceflight mice using a quantitative proteomic approach with data-independent acquisition mass spectrometry
Physical inactivity associated with gravity unloading, such as microgravity during spaceflight and hindlimb unloading (HU), can cause various physiological changes. In this study, we attempted to identify serum proteins whose levels fluctuated in response to gravity unloading. First, we quantitative...
