Mechanisms of specificity in neuronal activity-regulated gene transcription.
The brain is a highly adaptable organ that is capable of converting sensory information into changes in neuronal function. This plasticity allows behavior to be accommodated to the environment, providing an important evolutionary advantage. Neurons convert environmental stimuli into long-lasting changes in their physiology in part through the synaptic activity-regulated transcription of new gen...
متن کاملNucleosome mediated crosstalk between transcription factors at eukaryotic enhancers.
A recent study of transcription regulation in Drosophila embryonic development revealed a complex non-monotonic dependence of gene expression on the distance between binding sites of repressor and activator proteins at the corresponding enhancer cis-regulatory modules (Fakhouri et al 2010 Mol. Syst. Biol. 6 341). The repressor efficiency was high at small separations, low around 30 bp, reached ...
متن کاملNeuronal activity-regulated gene transcription: how are distant synaptic signals conveyed to the nucleus?
Synaptic activity can trigger gene expression programs that are required for the stable change of neuronal properties, a process that is essential for learning and memory. Currently, it is still unclear how the stimulation of dendritic synapses can be coupled to transcription in the nucleus in a timely way given that large distances can separate these two cellular compartments. Although several...
متن کاملNeuronal activity-regulated gene transcription in synapse development and cognitive function.
Activity-dependent plasticity of vertebrate neurons allows the brain to respond to its environment. During brain development, both spontaneous and sensory-driven neural activity are essential for instructively guiding the process of synapse development. These effects of neuronal activity are transduced in part through the concerted regulation of a set of activity-dependent transcription factors...
متن کاملCREB has a context-dependent role in activity-regulated transcription and maintains neuronal cholesterol homeostasis.
Induction of specific gene expression patterns in response to activity confers functional plasticity to neurons. A principal role in the regulation of these processes has been ascribed to the cAMP responsive element binding protein (CREB). Using genome-wide expression profiling in mice lacking CREB in the forebrain, accompanied by deletion of the cAMP responsive element modulator gene (CREM), w...
