As revealed by the univariate Cox regression analysis results, PTBP1 might be a risk factor for the prognosis of ACC, KICH, LGG, LIHC, LUAD, MESO, PRAD, SARC, and SKCM patients, while being a protective factor in KIRC, READ, and THYM (Figure 1(d)). This evidence concerns the gene PTBP1 and adrenal cortex carcinoma.
