On the other hand, elevated DPP4 expression correlated with poor prognosis in adrenocortical carcinoma (z_score = 2.047142556), acute myeloid leukemia (LAML; z_score = 2.234472636), brain lower grade glioma (LGG,z_score = 8.609548747), kidney renal papillary cell carcinoma (KIRP; z_score = −2.987857684), and LUSC (z_score = 2.103042397) (Figure 3A, Supplementary Table 1). This evidence concerns the gene DPP4 and adrenal cortex carcinoma.
