Disease relevance of Pspn

 

High impact information on Pspn

  • Our findings support the view that PSP signaling can exert an important control function in the context of stroke and glutamate-mediated neurotoxicity, and also suggest that future therapeutic approaches may involve this novel trophic protein [1].
  • Taken together, these data indicate that PSP is a potent modulator of excitotoxicity in the central nervous system with pronounced neuroprotective activity [1].
  • Human glial cell line-derived neurotrophic factor receptor alpha 4 is the receptor for persephin and is predominantly expressed in normal and malignant thyroid medullary cells [4].
  • Neurturin, artemin and persephin are homologs of GDNF, and their impact on axonal regeneration in adults has not been studied yet [2].
  • Glial cell line-derived neurotrophic factor family receptor (GFRalpha) 4, the binding receptor for persephin, is coexpressed with the signaling Ret receptor tyrosine kinase predominantly in thyroid calcitonin-producing C cells [5].
 

Biological context of Pspn

  • However, in 33% of cells studied in Kcna1-null slices bathed in normal extracellular medium, orthodromic stimulation evoked synaptically driven bursts of action potentials that followed a short-latency excitatory postsynaptic potential (EPSP)-inhibitory PSP (IPSP) sequence [6].
  • Although it is clear that female sexual behavior, including pacing behavior, is important for induction of P/PSP, there has been no concerted effort to examine whether or how common mechanisms may control both functions [7].
  • High-level parotid gland expression of the PSP gene was indicated to depend on a novel regulatory region situated between -8.0 and -6.5 kb [8].
  • This region was shown to activate a heterologus SV40 early promoter in the parotid glands of transgenic mice, suggesting that the PSP gene is controlled by enhancer sequences [8].
  • This paper will review both new and old data that address the question of whether brain mechanisms involved in reproductive function act in a coordinated way to control female sexual behavior and the induction of pregnancy/pseudopregnancy (P/PSP) by vaginocervical stimulation [7].
 

Anatomical context of Pspn

 

Associations of Pspn with chemical compounds

  • PSP toxin, anatoxin-a, homoanatoxin-a and microcystins were not detected when pond water from a diseased pond was tested [11].
  • Spatial and temporal evolution of PSP toxins along the Atlantic shore of Morocco [12].
  • NIH/Ola mice were given two intraperitoneal injections with ovalbumin (OVA; 10 microg) alone or OVA in combination with PSP, polytetrafluoroethylene (teflon), titanium dioxide (TiO(2)) or amorphous silica particles (2.8x10(10)-2.8x10(12)) [13].
