Expression of BRD4 was measured in different kinds of tumors, which was displayed using gene expression profiling interactive analysis (GEPIA, http://gepia.cancer-pku.cn/index.html), which illustrated that mRNA expression of BRD4 in tumor tissue was raised remarkably than that in normal tissue only in stomach adenocarcinoma (STAD) and esophageal adenocarcinoma (ESCA, Figure 1A). Here, BRD4 is linked to gastric adenocarcinoma.
