What Does MOTS-c Do?

Research on MOTS-c has revealed several potential benefits and applications, although further investigation is still needed to fully understand its therapeutic implications. Here are some MOTS-s uses and applications uncovered by research to date:

  • Obesity: One area of interest is the potential use of MOTS-c in obesity management. Seminal work conducted by Lee et al. (2015) on mice showed that MOTS-c injections alongside a high-fat diet resulted in significant weight reduction [5]. However, no weight reduction was observed in mice on a regular diet with MOTS-c injections. These findings suggest that MOTS-c may have implications for weight management, particularly in the context of a high-fat diet. Clinical trials are needed to assess the effectiveness and safety of MOTS-c in humans [5].
  • Metabolic disorders: According to Lu et al. (2019) MOTS-c also shows promise in addressing metabolic disorders. In studies involving mice, MOTS-c treatment prevented obesity and insulin resistance by activating brown fat, reducing fat accumulation, and decreasing inflammation [6]. The authors’ findings suggest potential benefits in mitigating metabolic changes in postmenopausal women. However, further research and human clinical trials are necessary to fully understand the therapeutic implications of MOTS-c for postmenopausal metabolic dysfunction [6].
  • Aging-related diseases: The potential of MOTS-c in connection with aging-related processes has also been explored. Research suggests that MOTS-c may enhance mitochondrial fitness, possibly increasing NAD+ levels, influencing metabolic pathways, and improving physical performance in mice. If these fhese findings translate to humans, it would mean that MOTS-c may have therapeutic potential with respect to age-related diseases [7].
  • Muscle performance: MOTS-c in combination with exercise training has shown promising effects on muscle performance. It enhances the expression of the PGC-1α gene, which governs mitochondrial biogenesis and energy metabolism, and activates exercise-sensitive signaling intermediates like AMPK, SIRT1, and PGC-1α [8].

These effects promote fatty acid oxidation, mitochondrial biogenesis, and enhance muscle metabolic capacity. The overlap between the effects of MOTS-c and exercise on genes related to angiogenesis, inflammation, and apoptosis suggests potential benefits in reducing the risk of metabolic disorders and cardiovascular complications [9].

Additionally, studies have suggested potential uses of MOTS-c in various areas such as:

  • Alzheimer disease
  • Immunity
  • Inflammation modulation
  • Osteoporosis
  • Postmenopausal disorders

To sum up, the initial findings on MOTS-c highlight its potential in addressing obesity, metabolic disorders, aging-related issues, and enhancing muscle performance. However, further research, including clinical trials, is necessary to establish its effectiveness, optimal applications in humans, and short-term and long-terms risks.


MOTS-c Side Effects and Safety

Since MOTS-c is a relatively new discovery, its safety profile is still being investigated, and further research is needed to fully understand potential side effects.

Laboratory animal studies have demonstrated positive outcomes with MOTS-c treatment, showing improvements in metabolic health, physical performance, and age-related decline. However, these studies have primarily focused on the efficacy and therapeutic potential of MOTS-c, rather than extensively examining its safety profile [5, 6].

To establish the safety of MOTS-c, it is crucial to conduct comprehensive toxicology studies in laboratory animals, including dose-response assessments, long-term exposure evaluations, and investigations into potential adverse effects.

Limited human studies have been conducted thus far to assess the safety and tolerability of MOTS-c. In a phase 1a/1b clinical trial of the MOTS-c analog CB4211, which was completed in 2021, the results suggested that CB4211 was generally well-tolerated with no serious adverse events reported [10].

However, it is important to note that this trial was conducted with a different analog of MOTS-c, and the findings may not directly apply to MOTS-c itself.

As with any investigational compound, it is essential to proceed with caution when considering the use of MOTS-c in humans. Rigorous safety evaluations, including controlled clinical trials, are necessary to assess potential side effects, drug interactions, and long-term effects.

Researchers and regulatory bodies need to continue conducting thorough investigations to ensure the safety and efficacy of MOTS-c before it can be approved for widespread therapeutic use in humans.
