BRD4 and hepatocellular carcinoma: In this respect, activation of the ASK1-dependent mitochondrial apoptosis pathway in hepatocellular carcinoma cells [68], inhibition of hedgehog/GLI signaling in medulloblastoma cells [63], or increased expression of BRD4- and MYC-dependent epithelial genes in pancreatic cancer cells [71] have been suggested as critical anti-tumorigenic outcome following inhibition of its primary targets by 4SC-202.
