Results from this study1

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

Natural levels measured1

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. 01LabEndogenous levelIn vitro (cells)Mechanism

    In the mdx mouse muscle cell line, thymosin beta4 was up-regulated, together with other genes, in a microarray comparison with the normal line.

    In plain wordsIn mouse muscle cells with the Duchenne model mutation, the body's own thymosin beta4 gene was more active than in normal cells.

    Summary
    We found that in the mdx muscle cell line, 12 genes, including L-arginine:glycine amidinotransferase and thymosin beta4, are up-regulated, whereas 7 genes, including selenoprotein P and a novel regeneration-associated muscle protease (RAMP), are down-regulated.

    Summary · context
    To identify these factors, we searched for mRNAs affected by the mdx mutation by using cDNA microarrays with newly established skeletal muscle cell lines from mdx and normal mice.

    This result measures the body's own Thymosin beta-4 (human). Nobody was given the peptide. It is not evidence about taking it.
