The glial cell line-derived neurotrophic factor (GDNF) ligands (GDNF, Neurturin [NTN], and Persephin [PSP]) signal through a multicomponent receptor system composed of a high-affinity binding component (GFRalpha1-GFRalpha4) and a common signaling component (RET). Here, we report the identification of Artemin, a novel member of the GDNF family, and(More)
A novel neurotrophic factor named Persephin that is approximately 40% identical to glial cell line-derived neurotrophic factor (GDNF) and neurturin (NTN) has been identified using degenerate PCR. Persephin, like GDNF and NTN, promotes the survival of ventral midbrain dopaminergic neurons in culture and prevents their degeneration after 6-hydroxydopamine(More)
The orphan nuclear receptor steroidogenic factor 1 (SF-1) is expressed in the adrenal cortex and gonads and regulates the expression of several P450 steroid hydroxylases in vitro. We examined the role of SF-1 in the adrenal glands and gonads in vivo by a targeted disruption of the mouse SF-1 gene. All SF-1-deficient mice died shortly after delivery. Their(More)
We have cloned NGFI-C, a nerve growth factor-induced early-response gene which encodes a Cys2/His2 zinc finger protein. RNA blot analysis demonstrates that NGFI-C mRNA is induced within minutes of stimulation of PC12 cells by nerve growth factor and is similarly activated in brain after a Metrazol-induced seizure. The cDNA sequence predicts a protein that(More)
The two Nab genes, coding for transcriptional corepressors of NGFI-A (Egr-1, Krox24, zif268) and Krox20, have been localized to two regions of the genome, each of which contains at least two members of the Stat gene family. The association of the two Nab genes with the Stat clusters on mouse chromosomes 1 and 10 (human chromosomes 2 and 12) suggest that a(More)
The nerve growth factor-induced clone C (NGFI-C) gene encodes a zinc-finger transcription factor that is rapidly induced by nerve growth factor in rat pheochromocytoma PC12 cells and by seizure in brain. NGFI-C is closely related to the previously described early response genes, nerve growth factor-induced clone A (NGFI-A or EGR1), EGR2, and EGR3. These(More)
