Results from this study4

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

Natural levels measured4

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. 01HumanEndogenous levelObservational studyMechanism

    In human breast tumors, cancer cells showed low or intermediate thymosin beta4 reactivity, while leukocytes and macrophages showed intense reactivity.

    In plain wordsIn human breast tumors, the body's own thymosin beta4 was low or intermediate in cancer cells and intense in immune cells.

    Summary
    In most tumors examined, cancer cells showed low or intermediate reactivity for thymosin beta4, whereas leukocytes and macrophages showed intense reactivity.
    1 context sentence
    Summary · context
    We now demonstrate that there is a considerable heterogeneity in the cellular distribution of thymosin beta4 in breast cancer.

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

  2. 02HumanEndogenous levelObservational studyMechanism

    In human breast tumors, endothelial cells showed variable thymosin beta4 reactivity, and myofibroblasts were negative.

    In plain wordsIn human breast tumors, the body's own thymosin beta4 varied in blood vessel lining cells and was absent in myofibroblasts.

  3. 03HumanEndogenous levelObservational studyMechanism

    In human breast cancer, tumor cell thymosin beta4 staining intensity did not correlate with histological grade.

    In plain wordsIn human breast cancer, the body's own thymosin beta4 staining in tumor cells was not linked to tumor grade.

  4. 04HumanEndogenous levelObservational studyMechanism

    In human breast cancer, endothelial cell thymosin beta4 staining showed a tendency toward correlation with histological grade.
