Mechanism & pathways

MOTS-c
  • Studied link AMPK activated through folate metabolism in cell and mouse studies

    An energy sensor inside cells. It switches on when a cell's energy runs low and shifts metabolism toward producing energy.

  • Studied link Insulin receptor & insulin signaling insulin sensitivity in mice

    Insulin, released by the pancreas, acts on the insulin receptor to move sugar out of the blood and into cells. Compounds can act upstream (more insulin released when blood sugar is high) or on how sensitive cells are to insulin.

  • NoteSkeletal muscle (its main target organ in mice)
Dashed boxes are studied or proposed links from early research, not confirmed actions. See MOTS-c on the pathway map
