During the past decade, 3ʹ untranslated regions (3ʹUTRs) of mRNAs continue to emerge as important sites for gene regulation due to the binding of microRNAs (miRs), RNA-binding proteins (RBPs) and possibly other trans-acting factors. Brain derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) play important roles inside and outside the central nervous system (...

The glial cell line-derived neurotrophic factor (GDNF) is a well-known growth factor acting on many neuronal populations of central, peripheral and autonomous nervous system. This factor was also previously detected in the retina of developing rat and chicken while no data are available for the zebrafish. In this study transcripts of GDNF mRNA were observed in adult retina extracts by RT-PCR. T...

We show with transgenic mice that targeted overexpression of glial cell line-derived neurotrophic factor (GDNF) in undifferentiated spermatogonia promotes malignant testicular tumors, which express germ-cell markers. The tumors are invasive and contain aneuploid cells, but no distant metastases have been found. By several histological, molecular, and histochemical characteristics, the GDNF-indu...

Nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) are proteins involved in neuronal survival and plasticity of dopaminergic, cholinergic and serotonergic neurons in the central nervous system. Since decreased size and impaired function of some neuronal populations may be relevant in depression it has been hypothesized that...

PURPOSE To investigate neurotrophic growth factors and corresponding receptors in human and rabbit corneal epithelium and stroma. METHODS Transcription of nerve growth factor (NGF), neurotrophin 3 (NT-3), NT-4, brain-derived neurotrophic factor (BDNF), glial cell line- derived neurotrophic factor (GDNF), and receptors Trk A-E, was investigated by reverse transcription-polymerase chain reactio...

To date, delivery of neurotrophic factors has only allowed to transiently protect axotomized facial motoneurons against cell death. In the present report, long-term protection of these neurons was evaluated by continuously expressing the neurotrophic factor glial cell line-derived neurotrophic factor (GDNF) within the facial nucleus using a lentiviral vector system. The viral vector was injecte...

Glial-cell-line-derived neurotrophic factor (GDNF) was originally identified as a survival factor for midbrain dopaminergic neurons. GDNF and related ligands, neurturin (NRTN), artemin (ARTN) and persephin (PSPN), maintain several neuronal populations in the central nervous systems, including midbrain dopamine neurons and motoneurons. In addition, GDNF, NRTN and ARTN support the survival and re...

Neurotrophic factors regulate the survival and growth of neurons, and influence synaptic efficiency and plasticity. Several studies suggest the existence of a relationship between changes in neurotrophic levels and bipolar disorder (BD). The glial cell-line derived neurotrophic factor (GDNF) influences monoaminergic neurons and glial cells, but its role in BD patients is controversial. In order...

We report the expression cloning and characterization of GDNFR-alpha, a novel glycosylphosphatidylinositol-linked cell surface receptor for glial cell line-derived neurotrophic factor (GDNF). GDNFR-alpha binds GDNF specifically and mediates activation of the Ret protein-tyrosine kinase (PTK). Treatment of Neuro-2a cells expressing GDNFR-alpha with GDNF rapidly stimulates Ret autophosphorylation...

Glial-cell-line-derived neurotrophic factor (GDNF) acts as a potent survival factor for many neuronal populations, including retinal ganglion cells (RGC), indicating a potential therapeutic role of GDNF for neurological disorders. To enhance the tissue distribution and applicability of the neurotrophin, we linked it to a protein transduction domain derived from the HIV TAT protein and tested it...
