Peptide Longevity Q&A ·
MOTS-c was effectively modulated by dietary graviola oil extract in lambs, supporting metabolic homeostasis and potentially influencing longevity-related factors such as adipokine levels and mitochondrial function.
What the research shows
This study investigated the effects of dietary graviola (Annona muricata L.) oil extract (GOE) on the growth performance and circadian rhythm profiles of biomarkers related to adipokine, cardiac, and mitochondrial function in 48 male Anatolian Merino lambs aged 2.5 months. The lambs were divided into a control group and three supplementation groups receiving 200, 400, and 600 mg/kg of GOE for a total of 70 days, with a 60-day trial period. The study was conducted under controlled environmental conditions with a 12-hour light/dark cycle. Blood samples were collected on specified days and times to analyze the serum levels of Apelin, cardiac troponin I (cTnI), BMAL1, MOTS-c, and bone morphogenetic protein-1 (BMCP1) using ELISA. The data were analyzed using GLM Multivariate analysis, with a significance level set at p < 0.05.
Why it matters for longevity
The modulation of MOTS-c and other biomarkers by dietary supplementation suggests a potential link between this peptide and metabolic health, which is crucial for longevity. In the context of aging, maintaining metabolic homeostasis is vital as it influences various physiological processes, including energy metabolism, fat storage, and cardiovascular health. The findings indicate that MOTS-c may play a role in enhancing mitochondrial function and regulating adipokine levels, both of which are important for preventing age-related decline and promoting overall healthspan.
Key findings at a glance
- The G400 dose of graviola oil extract significantly increased live weight and weight gain in lambs.
- MOTS-c levels peaked at specific times, indicating a potential circadian rhythm influence.
- The G200 dose improved feed conversion ratio without affecting total feed consumption.
- The G600 dose showed the best results for Apelin and cTnI, highlighting its impact on cardiac function.
- Overall, the study supports the use of GOE as a strategy to enhance metabolic health in livestock.
How MOTS-c works (background)
MOTS-c is a mitochondrial-derived peptide that has been implicated in various metabolic processes. It is known to influence energy metabolism, insulin sensitivity, and mitochondrial function. By modulating the expression of specific adipokines and other biomarkers, MOTS-c may help maintain metabolic balance, which is essential for health as organisms age. Research in animal models, such as the one conducted on lambs, provides insights into how dietary interventions can affect these pathways, potentially leading to improved health outcomes.
Safety, caveats, and what we don't yet know
While the study demonstrates significant effects of graviola oil extract on MOTS-c and other biomarkers in lambs, the findings are preclinical and may not directly translate to humans. Further research is needed to explore the long-term safety and efficacy of MOTS-c modulation through dietary supplements in various populations, including older adults. Additionally, the specific mechanisms by which MOTS-c influences metabolic health require further investigation to fully understand its potential benefits and limitations.
Bottom line
The modulation of MOTS-c through dietary graviola oil extract in lambs suggests a potential role in supporting metabolic health, which is crucial for longevity. However, more research is needed to establish its effects in human populations.

Can MOTS-c enhance mitochondrial function in elderly populations?
Research indicates that MOTS-c may improve mitochondrial function, which is critical for energy metabolism and overall health in aging individuals. However, specific studies in elderly populations are still needed to confirm these effects.
Does MOTS-c influence fat metabolism in older adults?
While MOTS-c has shown potential in modulating fat metabolism in animal models, further research is necessary to determine its specific effects on fat metabolism in older adults and its implications for weight management.
What role does MOTS-c play in age-related diseases?
MOTS-c may have a protective role against age-related diseases by supporting mitochondrial function and metabolic health. However, additional studies are required to clarify its involvement in specific age-related conditions.
