To identify a reliable marker of hypoxia linked to KDM6A status, we retrieved PDAC data from the ICGC and The Cancer Genome Atlas (TCGA) databases and found that in both cohorts the hypoxia‐related gene SCL2A1 (encoding for GLUT1) was significantly upregulated when KDM6A was inactive (see supplementary material, Figure S6B,C). This evidence concerns the gene KDM6A and cancer.
