Results from this study3

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

Natural levels measured3

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 studyOther

    In patients with non-small cell lung cancer, TMSB4X-positive expression was linked to shorter median disease-free survival than negative expression (11.3 vs 16.2 months).

    In plain wordsIn people with lung cancer, higher natural TMSB4X (Tβ4 gene) activity was linked to shorter time without disease return.

    Summary
    Compared to the TMSB4X positive expression group, patients in the negative expression group had a better prognosis, with longer DFS (median disease-free survival (median DFS): 16.2 months vs. 11.3 months, P = 0.032) and OS (median overall survival (mOS): 29.8 months vs. 18.5 months, P = 0.033).

    In our investigation, we meticulously analyzed the data of the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database, incorporating clinical patients and scrutinizing pathological specimens.

    In non-small cell lung cancer, TMSB4X expression correlated with activation of infiltrating dendritic cells (R = 0.27), which suggests a role in immune evasion.

    In plain wordsIn lung cancer, natural TMSB4X (Tβ4 gene) activity was linked to activation of immune dendritic cells. The authors suggest a role in immune escape.

    Summary
    Furthermore, our findings suggest that TMSB4X may facilitate immune evasion in non-small cell lung cancer cells by influencing the activation of infiltrating dendritic cells (DCs) in tumor infiltrating immune cells (TIICs) (R = 0.27, P = 4.8E+08).
