What is MOTS-c?
MOTS-c (mitochondrial open-reading-frame of the twelve S rRNA-C) is a 16 amino acid peptide naturally produced in the human body and classified as a mitochondria-derived peptide (MDP).
It has been found to play an important role in regulating metabolism and weight loss, improving athletic performance, and enhancing longevity . Above all, mitochondria-derived peptides like MOTS-c play a “cytoprotective role in maintaining mitochondrial function and cell viability under pressure” .
MOTS-c is found in skeletal and muscle tissue, and in various organs such as the liver and brain. It helps to regulate metabolic functions in the body, including the conversion of glucose into usable energy. MOTS-c increases glucose uptake in muscle cells by activating the AMP-activated protein kinase (AMPK) pathway, without increasing insulin. AMPK is a key energy-sensing kinase and a master metabolic regulator that is triggered by metabolic stress [1, 3, 4].
The peptide is sometimes referred to as an exercise‐mimetic, meaning it can imitate the mechanism of exercise on the body; exercise itself induces endogenous MOTS-c expression in both skeletal muscle and circulation in humans .
MOTS-c has been found to produce varied benefits in test subjects, including facilitating weight loss, improving longevity, and reducing insulin resistance.
MOTS-c and body composition
MOTS-c works by increasing the body’s usage of energy by targeting the skeletal muscle and enhancing glucose metabolism. In the skeletal muscle, the peptide’s cellular actions slow down the folate cycle and result in AMPK activation.
A 2015 study conducted on mice being administered a high-fat diet showed that MOTS-c prevented diet-induced obesity [3, 6]. Researchers have also found that increasing AMPK can affect the expression of genes associated with inflammation, which typically contributes to weight gain .
MOTS-c and longevity
Research on MOTS-c has revealed possible properties related to aging phenomena. In a 2015 study, researchers found that the m.1382A>C polymorphism, located in the MOTS-c encoding mtDNA, may play a role in the longevity of the Japanese—the population with the longest average life expectancy in the world. Based on this study, the researchers proposed a “biological link between MOTS-c and extended lifespan through the putative endocrine action of this mitokine” .
MOTS-c attenuates insulin resistance
Researchers have found that MOTS-c is important to promoting insulin sensitivity. MOTS-c treatment has been shown to prevent both diet-induced and age-dependent muscle insulin resistance in mice, acting as a regulator of metabolic homeostasis .
In a 2012 human study, researchers investigated whether there was a relationship between plasma MOTS-c levels and insulin sensitivity surrogates, in both lean and obese subjects. The researchers found that MOTS-c was positively associated with insulin sensitivity in the lean subject group, but not in the obese individuals .
MOTS-c and muscle atrophy
Myostatin is responsible for limiting the amount of skeletal muscle mass on the body. It also mediates insulin resistance-induced skeletal muscle wasting.
A 2021 study found an inverse correlation between plasma MOTS-c and myostatin levels in human subjects. The researchers observed that by elevating AKT phosphorylation, MOTS-c inhibits the activity of myostatin and other muscle wasting genes. They proposed MOTS-c as a potential treatment of insulin resistance-induced skeletal muscle atrophy and other muscle wasting conditions .
MOTS-c and bone health
A 2018 study found that MOTS-c treatment could stimulate the formation of calcified nodules in the bone marrow stromal cells (BMSC) of rats afflicted with osteoporosis. The researchers found that MOTS-c administration upregulated the TGF-β/Smad pathway-related genes, leading to osteogenic differentiation and improvement of symptoms of osteoporosis .
Another 2016 study sought to evaluate whether MOTS-c could protect mice from osteoporosis after an ovariectomy. Following ovary removal, the rodents were injected with a MOTS-c dose of 5 mg/kg once daily for 12 weeks. The researchers found that MOTS-c administration greatly alleviated bone loss in the test subjects .
MOTS-c Side Effects
MOTS-c is a research peptide and has not undergone any large-scale safety studies in humans.
However, there is data on the safety profile of CB4211, a novel analog of MOTS-c. This mitochondria-based therapeutic has been evaluated for safety in a phase 1a/1b double blind, placebo-controlled clinical trial in healthy adults, with the researchers finding it safe and well-tolerated [12, 13, 14].
There may also be sex-based differences in how MOTS-c works. Compared to females, male subjects have been shown to exhibit a greater disruption in MOTS-c in contexts of metabolic disease. Researchers have proposed that the protective properties of estrogen may inhibit the decline of MOTS-c in premenopausal women .
For this reason, researchers believe that MOTS-c therapy may be more effective in males than in females .
Since MOTS-c works by activating AMPK, the peptide interacts with other AMPK-activating drugs like metformin .
MOTS-c Dosage Calculator and Guide
MOTS-c must be reconstituted with bacteriostatic water prior to being administered via subcutaneous injection.
Follow the below steps to reconstitute MOTS-c for injection:
- Remove the tops of the MOTS-c and bacteriostatic vials and wipe their surfaces with an alcohol swab to prevent contamination and infection.
- Insert a sterile drawing syringe into the bacteriostatic water vial and draw the desired amount, typically 1-2 ml, but dependent on the dose.
- Slowly transfer the bacteriostatic water into the MOTS-c vial, allowing it to trickle down the side of the vial while dissolving the powder.
- Do not shake or stir MOTS-c vials, as doing so may compromise the peptide. The solution to be injected should appear clear when fully mixed.
- Place the unused solution in refrigeration for future use.
Based on the research available, researchers are advised to administer MOTS-c in the morning as it may interfere with the research subject’s sleep.
Sample MOTS-c Protocol for Weight Loss
Currently, there is a lack of clinical data to suggest a potential dosing regime. The available data from mice studies suggest dosing of up to 15mg/kg/day for three days a week, while a potential experimental dose in human trials should be more than 10-fold lower [5, 17].
Thus, researchers are recommended to administer doses no greater than 5-10mg/day and no more frequently than 1-3 times a week. At Peptides.org, we recommend applying up to 5mg/day once every 5 days for up to 20 days.
Here is a reference MOTS-c protocol that researchers may administer to observe fat loss in subjects:
- MOTS-c Dosage: 5mg in the morning, preferably before exercise.
- Frequency: Administer every five days.
- Study Duration: 20 days.
- Repeat: It is advisable to administer a second identical cycle within six months of completing the initial study.
- Notes: Researchers require two MOTS-c 10mg vials to complete the one-month weight loss protocol described above.
