Hypothesis
The study aimed to examine the differentially expressed miRNAs in plasma of older adults in relation to muscle mass, strength, and performance status.
Conclusion
Increased levels of specific miRNAs could serve as candidate plasma biomarkers for the decline of muscle strength in older adults.
Supporting Evidence
- Three differentially expressed miRNAs were significantly increased in the plasma of the 'LMS only' group.
- The study categorized participants based on sarcopenia criteria from the Asian Working Group for Sarcopenia 2019.
- The Kyoto Encyclopedia of Genes and Genomes analysis showed that the miRNAs were related to neurotrophin signaling pathway.
Takeaway
The study found that certain tiny molecules in the blood can help identify older people who are losing muscle strength.
Methodology
Participants were categorized into four groups based on sarcopenia criteria, and miRNA profiles were established and validated using RT-qPCR.
