BRD4 and neoplasm: Down-regulated genes (1,435 gene elements, fold change >1.5) after JQ1 treatment were prominent in liver tumors compared to adjacent non-tumor liver cells, while up-regulated genes (135 gene elements, fold change >1.5) are underexpressed in liver tumors (Figure 2A), suggesting that BRD4 inhibition could reverse liver cancer related gene expression signature.
