High GBP1 expression was associated with poor OS prognosis for patients with KIRP (p = 0.0061), LGG (p < 0.001), thymoma (THYM) (p = 0.026), and uveal melanoma (UVM) (p = 0.0018), while high GBP1 expression conferred a better prognosis for patients with OV (p = 0.0038) and SKCM (p < 0.001) (Supplementary Figure S3A). Here, GBP1 is linked to thymoma.
