Understanding how apelin affects muscle regeneration as we age

Official title: Apelin Signaling in Muscle Regeneration

Funded at University of Maine Orono · NIH-11080328 · Data updated 2026-11-12

This study is looking at how a substance called apelin helps muscles heal and grow back, especially as we get older and face muscle loss, using zebrafish to learn more about how it works with different cells in the body.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults, particularly those over 80 years of age, who are experiencing muscle loss or related mobility issues.

Less likely to help

Patients who are younger and do not have age-related muscle decline or sarcopenia may not benefit from this research.

What this research studies

This research investigates the role of the apelin signaling pathway in muscle regeneration, particularly in the context of aging and age-related muscle loss, known as sarcopenia. By using zebrafish as a model, the study aims to explore how apelin influences communication between muscle stem cells, endothelial cells, and immune cells to enhance muscle recovery. The researchers will employ advanced techniques, including pharmacological interventions and single-cell RNA sequencing, to uncover the mechanisms by which apelin promotes muscle health and combats age-related decline.

Why it matters

Potential benefit: If successful, this research could lead to new therapies that improve muscle regeneration and function in older adults, potentially reducing the risks associated with sarcopenia.

How similar studies have gone: Previous studies have shown promising results with apelin treatments in animal models, indicating potential for success in this area of research.
