abstract：:Hypoxia induces survival signals in hepatocellular carcinoma (HCC). We attempted to find a hypoxia-induced signal that could be used for modulating HCC cell death. Cellular retinoic acid binding protein-II (CRABP-II) expression was significantly increased in hypoxic HCC cells. Treatment with retinoic acid (RA), a liga...
