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 normal rats, plantaris MGF mRNA 3 days after overload was significantly higher than in normal controls.

    In plain wordsIn rats, the body's own muscle MGF messenger RNA was higher 3 days after overload than in controls.

    Summary
    IGF-I Ea and MGF mRNAs in normal-overloaded and hypophysectomized-overloaded 3 days after overload were significantly higher than those of normal-control and hypophysectomized-control, respectively.
    2 context sentences
    Summary · context
    To determine whether IGF-I Ea, MGF, and myostatin mRNAs are related to GH-independent overload-induced muscle growth, we examined the expressions of IGF-I Ea and MGF mRNAs in the plantaris muscle after compensatory overload in hypophysectomized rats.
    Summary · context
    The muscles were divided into four groups: normal-control, normal-overloaded, hypophysectomized-control, and hypophysectomized-overloaded.

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

    In hypophysectomized rats, plantaris MGF mRNA 3 days after overload was significantly higher than in hypophysectomized controls.

    In plain wordsIn rats without a pituitary gland, the body's own muscle MGF messenger RNA was higher 3 days after overload than in controls.
