Механизм действия
MOTS-c
MOTS-c arises from a short open reading frame located in the 12S rRNA region of the mitochondrial genome — unlike most peptides it is therefore not encoded by nuclear DNA. Mechanistically, preclinical work describes MOTS-c as modulating the folate cycle and the de novo purine biosynthesis tethered to it, thereby affecting the AMP/ATP ratio and, downstream, AMP-activated protein kinase (AMPK). Under metabolic stress, an AMPK-dependent translocation of the peptide into the cell nucleus and involvement in the regulation of stress-responsive genes (including via antioxidant-response-element-regulated transcription factors) have also been reported. These models derive predominantly from cell culture and rodents; the extent to which they reflect human physiology after administration of exogenous synthetic MOTS-c is not established by human studies.
Sekretin
Secretin binds the Gs-coupled secretin receptor (SCTR) on pancreatic duct cells, opens CFTR chloride channels and triggers secretion of bicarbonate-rich pancreatic fluid and bile flow.

Frequently asked questions
- What is the difference between MOTS-c and Sekretin?
- MOTS-c is classified as "Исследования (прочее)", while Sekretin is classified as "Исследования (прочее)". MOTS-c: MOTS-c is a 16-amino-acid mitochondrial-encoded peptide (mitochondrial-derived peptide, MDP) whose open reading frame lies within the 12S rRNA region of mitochondrial DNA. In basic research (including the laboratories of Changhan Lee and Pinchas Cohen) it is described as a regulator of metabolic homeostasis and an activator of the AMPK pathway, and is sometimes discussed as an 'exercise mimetic'. The evidence comes almost entirely from cell and animal models; controlled human trials of MOTS-c as a therapeutic are lacking. It is not approved as a medicine anywhere and is traded on the grey market as a research chemical. Sekretin: Secretin is a 27-amino-acid hormone that regulates pancreatic bicarbonate secretion. As ChiRhoStim it is FDA-approved as a diagnostic agent (pancreatic function test, gastrinoma test, secretin-enhanced MRCP). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, MOTS-c or Sekretin?
- The highest available evidence level is "Исследование на людях" for MOTS-c and "Исследование на людях" for Sekretin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of MOTS-c and Sekretin in Germany and the United States?
- Германия: MOTS-c — Не одобрено, Sekretin — Рецептурный. США: MOTS-c — Не одобрено, Sekretin — Рецептурный. These are factual summaries with source and review date on the individual pages.
