Neurotrophin regulation of gene expression.

The neurotrophins comprise a family of secreted proteins that elicit profound responses in cells of the developing and mature vertebrate nervous system including the regulation of neuronal survival and differentiation. The molecular mechanisms by which the neurotrophins exert their effects have been the subject of intense investigation. The neurotrophins elicit responses in neurons via members ...

Dlx2 homeobox gene transcriptional regulation of Trkb neurotrophin receptor expression during mouse retinal development

Dlx homeobox genes are first expressed in embryonic retina at E11.5. The Dlx1/Dlx2 null retina has a reduced ganglion cell layer (GCL), with loss of late-born differentiated retinal ganglion cells (RGCs) due to increased apoptosis. TrkB signaling is proposed to regulate the dynamics of RGC apoptosis throughout development. DLX2 expression markedly precedes the onset of TrkB expression in the GC...

Dynamic regulation of the expression of neurotrophin receptors by Runx3.

Sensory neurons in the dorsal root ganglion (DRG) specifically project axons to central and peripheral targets according to their sensory modality. However, the molecular mechanisms that govern sensory neuron differentiation and the axonal projections remain unclear. The Runt-related transcription factors, Runx1 and Runx3, are expressed in DRG neuronal subpopulations, suggesting that they might...

Regulation of neurotrophin receptor expression during embryonic and postnatal development.

Members of the NGF family of proteins act as neurotrophic agents for defined populations of peripheral and central neurons during embryonic and postnatal development. We have studied the presence of receptors for brain-derived neurotrophic factor (BDNF) and neurotrophin-3 and -4/5 (NT-3, NT-4/5) by cross-linking radioiodinated neurotrophins to specific cell surface receptors. We have identified...

Regulation of Gene Expression

For all living cells, regulation of gene expression by extracellular signals is a fundamental mechanism of development, homeostasis, and adaptation to the environment. Indeed, the ultimate step in many signal transduction pathways is the modification of transcription factors that can alter the expression of specific genes. Thus, neurotransmitters, growth factors, and drugs are all capable of al...
