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 human renal cancer cells, introduction of wild-type VHL specifically downregulated Cap43 among 9 tested genes that included thymosin beta‑4; thymosin beta‑4 was not named as downregulated.

    In plain wordsIn kidney cancer cells, adding VHL lowered only Cap43 among 9 genes. The body's own thymosin beta‑4 gene was not named as lowered.

    Summary
    Of these 9 genes, expression of the Cap43 gene was specifically downregulated by VHL.
    2 context sentences
    Summary · context
    We previously identified 9 genes (i.e., thymosin beta4, secreted protein acidic and rich in cysteine, Cap43, ceruloplasmin, serum amyloid A, heat shock protein 90, LOT1, osteopontin and casein kinase Igamma) that are more highly expressed in cancerous regions than in noncancerous regions in human renal cancers.
    Summary · context
    We first established 2 VHL-positive cell lines, 786/VHL-1 and 786/VHL-2, after the introduction of wild-type VHL into VHL-negative renal cancer 786-O cells.

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