Purkinje cell protein-2 (Pcp2 or L7) is highly expressed in cerebellar Purkinje cells and retinal bipolar neurons and interacts with the Gαi/o family of G-proteins. Although the expression pattern of Pcp2 in the developing central nervous system suggests a role in differentiation, its function remains unknown. We established Tet-off inducible expression of Pcp2 in PC12 cells (rat pheochromocyto...

We have identified a unique heparan sulfate (HeS) proteoglycan synthesized by the neuronal-like cell line PC12. The proteoglycan, purified with monoclonal antibodies from medium conditioned by PC12 cells, has an apparent molecular weight of 350,000, and it contains a Mr 80,000 core protein and HeS side chains of Mr 15,000 each. The purified molecule has the same apparent size and density as it ...

The cytoskeleton of the rat cultured cell line PC12, which is widely used in cell biology as a model system for neuron-like differentiation, displays an unusual combination of intermediate-sized filaments (IFs). As determined by electron microscopy, immunolocalization, and biochemical analyses, these cells contain, in addition to neurofilaments, an extended meshwork of bundles of cytokeratin IF...

We previously described a novel in vitro model of a non-productive herpes simplex virus type 1 (HSV-1) infection in neurally differentiated (ND)-PC12 cells that allows for inducible virus replication upon forskolin and heat stress (HS) treatment. In this research, we further characterized the model with respect to HSV-2 strain 333. We found that: (i) ND-PC12 cells are non-permissive to HSV-2 re...

AIM To study the effect of group I metabotropic glutamate receptor (mGluR) ligands on 6-hydroxydopamine (6-OHDA)-induced death and glutamate release of PC12 cells. METHODS PC12 cells were exposed to 100 micromol/L of group I mGluR agonist (RS)-3,5-dihydroxy-phenylglycine (DHPG) or antagonist DL-2-amino-3-phosphonopropionic acid (DL-AP3) 1 h before addition of 6-OHDA 100 micromol/L. After incu...

BACKGROUND Alzheimer's disease (AD) is one of the common neurodegenerative disorders among elderly. The purpose of this study was to determine the neuroprotective effect and mechanisms of action underlying the Terminalia chebula extracts and ellagic acid by using beta-amyloid25-35 (Aβ25-35)-induced cell toxicity in an undifferentiated pheochromocytoma (PC12) cell line. MATERIALS AND METHODS T...

In order to search for novel components of lipid membrane microdomains involved in neural signalling pathways, mAbs (monoclonal antibodies) were raised against the detergent-insoluble membrane fraction of PC12 (pheochromocytoma) cells. Among the 22 hybrid clones, mAb PR#1 specifically detected a fucoganglioside Fuc(Gal)-GM1 [α-fucosyl(α-galactosyl)-GM1], a ganglioside homologous with GM1a (IINe...

alzheimer’s disease (ad) is a neurodegenerative disease that was characterized with deposit of beta amyloid (aβ) aggregate in senile plaque. oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. melissa officinalis is a medicinal plant from lamiaceae family, used traditionally in the treatment of cognitive disorders. it has cholinomimetic ...

The PC12 line of nerve growth factor (NGF)-responsive rat pheochromocytoma cells was used as a model system to determine whether properties of microtubules change during neurite growth and maturation. In the absence of NGF, PC12 cells lack processes. After several days with NGF, PC12 cells begin extending neurites and, by 2-3 wk with NGF, PC12 cells have long (approximately 1 mm), highly branch...
