Results from this study7

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

Natural levels measured7

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 leukemic cells from patients, the thymosin beta‑4 gene was highly expressed in a lymphoid lineage, especially adult T-cell leukemia cells, rather than in a granulocyte lineage.

    In plain wordsIn leukemia cells from patients, the body's own thymosin beta‑4 gene was more active in lymphoid than in granulocyte cells.

    Summary
    Among leukemic cell samples obtained from leukemia patients, the T beta 4 gene was highly expressed in a lymphoid lineage, especially in adult T-cell leukemia (ATL) cells, rather than in a granulocyte lineage.
