miRNA miRNA marker for diagnosing muscle aging and a diagnostic method using the same

摘要

The present invention relates to a composition, kit, and method for diagnosing muscle aging in an individual by measuring the expression level of a specific miRNA, and a method for diagnosing muscle aging using the same. The two miRNAs (cfa-miR-103 and cfa-let-7a) of the present invention are It was confirmed that the expression level is changed in an individual in an age-dependent manner by ignoring the sample type. The two miRNAs can be used as biomarkers for diagnosing muscle aging, and when using them, invasive biopsy is not required. There are advantages.
