BRD4 and neoplasm: 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).
