DDOST and glioblastoma: Results showed that significant upregulation of DDOST was observed in 19 tumors, such as GBM (tumor: 7.37 ± 0.46, normal: 6.15 ± 0.07, p = 2.0e-4) and CESC (tumor: 7.51 ± 0.53, normal: 6.95 ± 0.13, p = 0.03), while DDOST was downregulated in only 2 tumors, namely, THCA (tumor: 7.32 ± 0.47, normal: 7.69 ± 0.36, p = 3.6e-11) and KICH (tumor: 6.18 ± 0.56, normal: 6.97 ± 0.31, p = 2.1e-21) (Figure 1A).
