Results from this study2

No result from this study comes from a test of the peptide.

Natural levels measured2

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In rats after myocardial infarction, exercise regulated the expression of the body's own MGF in soleus muscle.

    In plain wordsIn rats after a heart attack, exercise changed the body's own MGF level in a leg muscle. The direction is not stated.

    Summary
    Exercise down-regulated the mRNA levels of murf1 and atrogin-1, decreased reactive oxygen species level, increased antioxidant capacity, regulated the expression of insulin-like growth factor 1 (IGF1), mechano growth factor (MGF), Neuregulin1 (NRG1) and Myostatin (MSTN), and activated Akt and Erk1/2…

    Summary · context
    Rats were subjected to four weeks of different types of exercise after MI surgery (resistance training, RT; moderated-intensity continuous aerobic exercise, MCE and high-intensity intermittent aerobic exercise, HIA).

    This result measures the body's own MGF / PEG-MGF. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In rats after myocardial infarction, MGF expression in skeletal muscle correlated with cardiac function.

    In plain wordsIn rats after a heart attack, the body's own MGF level in muscle was linked to heart function.
