Epigenetic regulation of vertebrate Hox genes: a dynamic equilibrium.
Temporal and spatial control of Hox gene expression is essential for correct patterning of many animals. In both Drosophila and vertebrates, Polycomb and Trithorax group complexes control the maintenance of Hox gene expression in appropriate domains. In vertebrates, dynamic changes in chromatin modifications are also observed during the sequential activation of Hox genes in the embryo, suggesting that progressive epigenetic modifications could regulate collinear gene activation.
