DNER and gastric neoplasm: We wished to further investigate whether expressions of BET proteins were associated with that of PRDM1 in stomach cancer in the TCGA dataset and Cancer Cell Line Encyclopedia (CCLE), and such analysis with cBioPortal showed that BRD4 was positively associated with PRDM1 (Figure 2C), while BRD2 and BRD3 were not; additionally, PRDM1-high stomach cancer cell lines tended to express more BRD4 (Figure 2D).
