To determine the correlation between DUBR expression and cancer, we analyzed GEPIA data and found that DUBR was significantly upregulated in LAML, cholangiocarcinoma (CHOL), brain lower grade glioma (LGG), sarcoma (SARC), glioblastoma multiforme (GBM), head and neck squamous cell carcinoma (HNSC), pancreatic cancer (PAAD), gastric cancer (STAD), and thymoma (THYM). This evidence concerns the gene DUBR and gastric adenocarcinoma.
