Gene dynamics and nuclear architecture during differentiation

Recent advances have demonstrated that placing genes in a specific nuclear context plays an important role in the regulation of coordinated gene expression, thus adding an additional level of complexity to the mechanisms of gene regulation. Differentiation processes are characterized by dynamic changes in gene activation and silencing. These alterations are often accompanied by gene relocations in relation to other genomic regions or to nuclear compartments. Unraveling of mechanisms and dynamics of chromatin positioning will thus expand our knowledge about cellular differentiation.
