Hormone Control Of Rare Leukemia Sheds Light On Molecular Basis Of Cancer
... Retinoic acid and its receptor regulate gene expression using a complexinterplay of blocking and activating molecules. In the absence of retinoic acid,the receptor blocks a gene by binding to a co-repressor. In the presence of thehormone, the co-repressor is released and a co-activator turns a gene on.
