We used the expression levels of 8 hypoxia‐related genes, namely DDIT4, LDHA, MXI1, NDRG1, P4HA1, PGK1, SLC2A1, and VEGFA, that we previously showed to be induced under hypoxic conditions in a panel of cancer cell lines, including those of breast cancer origin [11]. The gene discussed is DDIT4; the disease is cancer.
