As shown in Figure 3(a), high expression of VDAC1 was related to the poor overall survival of ACC, BRCA, CESC, GBM, LUAD, PAAD, SKCM, and UVM cases, and low VDAC1 expression was associated with a poor overall survival prognosis of KIRC cases based on the TCGA project (P < 0.05). Here, VDAC1 is linked to cervical squamous cell carcinoma.
