Fig. 1. Mitochondrial open reading frame of the 12S ribosomal RNA type-c (MOTS-c) prevents type 1 diabetes mellitus (T1DM). T1DM is an autoimmune disease. Activated autoreactive T-cells such as Th1 cells from secondary lymphoid organs (i.e., spleen or pancreatic lymph nodes) infiltrate into the pancreas and cause β-cell destruction. MOTS-c regulates T-cell differentiation and activation (e.g., upregulation of Treg cells) in an mechanistic target of rapamycin complex 1 (mTORC1)-dependent manner and prevents pancreatic infiltration of autoreactive T-cells in non-obese diabetic (NOD) mice. MOTS-c inhibits mTORC1 to lower glycolysis, which influences T-cell differentiation and activation. Inhibition of mTORC1 results in lowered glycolysis, lowered interleukin gamma (IFN-γ), and increased forkhead box P3 (Foxp3) expression level. As a result, MOTS-c treatment in T-cells lowers glycolysis to favor Foxp3+ Treg differentiation and lowers T-cell activation in NOD mice and T1DM patients. TCR, T-cell receptor; 4E-BP1, 4E binding protein 1; S6K, S6 kinase.

Fig. 2. Mitochondrial open reading frame of the 12S ribosomal RNA type-c (MOTS-c) reduces insulin resistance in high-fat diet (HFD) induced obese mice. Obesity is associated with increased insulin resistance. MOTS-c targets the skeletal muscle to regulate metabolic homeostasis. MOTS-c increase 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside (AICAR) and activates AMP-activated protein kinase (AMPK). This leads to the upregulation of glucose transporter type 4 (GLUT4) expression level in muscle cells. GLUT4 is a glucose transporter that is responsible for glucose uptake in the skeletal muscle and adipose tissues. MOTS-c treatment in HFD induced obese mice prevents obesity and hyperinsulinemia by regulating GLUT4 in an AMPK-dependent manner. PI3K, phosphoinositide 3-kinase; GSV, GLUT4 storage vesicle.

Fig. 3. Mitochondrial open reading frame of the 12S ribosomal RNA type-c (MOTS-c) is a potential target against aging-related diseases. Aging is associated with number of diseases. Traditionally, drug discovery efforts target each of these diseases individually. A complementary approach is to develop a therapeutic reagent to treat the root of these diseases, dubbed geroscience. MOTS-c is a potential therapeutic target for multiple aging-related diseases, including neurodegeneration, osteoporosis, cardiovascular disease, atherosclerosis, sarcopenia, type 2 diabetes mellitus, and obesity. Future studies are needed to unveil the efficacy and safety of MOTS-c treatment for aging-related diseases.

DOSAGE SOURCE

MOTS-c Dosage Protocols

Standard Protocol 5 mg Once or twice weekly 8-12 weeks Performance and Recomp Protocol 10 mg/week (split into 2 doses of 5 mg) Twice weekly Anti-Aging and Metabolic Maintenance Once weekly 8-12 weeks, cycled 2-3 times per year Standard Protocol: Inject subcutaneously. Start with 5 mg once per week for the first 2 weeks to assess tolerance, then increase to twice weekly if desired. Most users settle on 5 mg three days apart. Performance and Recomp Protocol: For body recomposition and exercise performance goals. Inject on training days, ideally 1-2 hours before exercise. The AMPK activation will enhance the metabolic response to training. Anti-Aging and Metabolic Maintenance: For general metabolic health and longevity. Once weekly is sufficient for maintenance-level AMPK activation and mitochondrial support. Cycle on and off to avoid chronic pathway desensitization. These are general guidelines for research purposes. Always consult a healthcare professional before use.

“The formulation isn’t reviewed by the FDA before it reaches anyone,” says Sogol Ash, NMD, longevity director at ConciergeMD and Drip Hydration in Los Angeles. “Compounding pharmacies are overseen primarily by state boards, rather than under manufacturer-level federal oversight.”

RESEARCH

How Is MOTS-C Used in Health and Research?

The most important thing to understand about the uses of MOTS-C is that it is a research chemical. This means it is used by scientists and in laboratories for scientific studies. It is not an FDA-approved medication and is not meant for human consumption. This is a crucial distinction that must always be respected. The uses of MOTS-C are in a research context, where scientists are exploring its potential benefits and trying to better understand its mechanisms of action. This is how all new medications are developed, and it is a necessary part of the process. In a research setting, MOTS-C is used to study a variety of conditions. Researchers may use it to investigate how it affects metabolic pathways, how it influences insulin sensitivity, or how it impacts physical performance. These studies are designed to gather data that will one day help determine if MOTS-C can be developed into a safe and effective medication for human use.
