Moreover, we used the TCGA database to analyze the correlation of DDX39B with other genes in the same subgroup and found that DDX39B expression was positively associated with DHX36, EIF3B, EIF3D, EIF3E, FUS, HSPD1, NUP153, RPL18A, RPL19, RPS27, SREK1, and USP34 in colon adenocarcinoma (Supplementary Fig. 1a). This evidence concerns the gene HSPD1 and colon adenocarcinoma.
