The results showed that these ER stress factors were generally highly expressed in gastrointestinal pan-cancer, with more obvious differential expression in COAD, LIHC, and ESCA; among which, DDX11, DKC1, EXOSC5, NOP56, and other genes were differentially expressed in the most cancer types, as shown in Figure 1A. This evidence concerns the gene DKC1 and cancer.
