  1. 01LabIn vitro (cells)Efficacy outcome

    In cultured cells, exogenously added thymosin alpha‑1 had no effect on cell growth.

    Summary · context
    The studies presented in this report evaluated both exogenously added T alpha 1 and endogenously expressed T alpha 1 as factors which could either promote growth of tumor cells or induce transformation.

Studies that did not test the peptide alone2

In this study, Thymosin alpha-1 was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin alpha-1.

  1. 02LabNot a test of Thymosin alpha-1 aloneIn vitro (cells)Efficacy outcome

    In NIH-3T3 cells transfected with ProThymosin alpha cDNA that expressed elevated thymosin alpha‑1, proliferation in liquid culture was not enhanced.

    In plain wordsIn cells that made extra thymosin alpha‑1 themselves, lab tests showed no faster growth.

    Summary
    NIH-3T3 cells transfected with cDNA for the precursor ProThymosin alpha (Pro T alpha) expressed elevated levels of authentic T alpha 1 but did not demonstrate either enhanced proliferation in liquid culture or transformation as defined by the loss of contact inhibition or anchorage independent growth in soft agar.

    In NIH-3T3 cells transfected with ProThymosin alpha cDNA that expressed elevated thymosin alpha‑1, there was no transformation, with no loss of contact inhibition and no anchorage-independent growth in soft agar.

    In plain wordsIn cells that made extra thymosin alpha‑1 themselves, lab tests showed no signs of cancer-like transformation.
