Further analysis using Kaplan–Meier survival curves demonstrated that lower expression of PLEK2 was related to better OS in ACC, GBM, LGG, LIHC, LUAD, MESO, OV, PAAD, SARC, SKCM, and UVM (Figures S5a, i, o and S6a, b, d, e, f, j, k, and r, respectively). This evidence concerns the gene PLEK2 and adrenal cortex carcinoma.
