| Outline of Final Research Achievements |
The early diagnosis for Sarcopenia is an urgent need for preventing irreversible muscle atrophy and for proper treatment. We succeeded in developing high sensitive multiple simultaneous Tag (MUSTag) method using specific biomarker (Protein A) for sarcopenia. In this assay, the sensitivity was calculated as 16 pg/mL (R2≧0.95) and 0.6 pg/mL (3×S.D.) in the healthy volunteer, the range is less than 300 pg/ml, but the values were measured from 500-4,800 pg/ml in patients of sarcopenia.
These results suggested the following possibilities; (1) the concentration of serum protein A shows the tendency of increase in the condition in which anabolic metabolism is promoted in the normal muscle volume. (2) in the contrast, the concentration does the tendency of decrease in the condition in which catabolic metabolism is promoted in such as inflammation and enhancement of the metabolism.
