We have established a ricin-resistant glycosylation-defective PC12 pheochromocytoma cell line to study biochemically glycoprotein traffic from the cell surface to the Golgi apparatus in regulated secretory cells. The strategy employed in this study is a modification of that used previously (Duncan, J. R., and Kornfeld, S. (1988) J. Cell Biol. 106, 617-628) to demonstrate transport of the cation...
Xeno-estrogens, a class of endocrine disrupting chemicals (EDCs), can disturb estrogen receptor-dependent pathways involved in differentiation, proliferation or protection. Multiple methods have been developed to characterize the disturbances induced by EDCs in different cells or organs. In this study we have developed a new tool for the assessment of estrogenic compounds on differentiation. Fo...
The PC12 clone is a line of rat pheochromocytoma cells which undergoes neuronal differentiation in the presence of nerve growth factor (NGF) protein. In the absence of NGF, PC12 cells are electrically inexcitable, while after several weeks of NGF treatment, they develop sodium action potentials. The number and density of sodium channels on PC12 cells before and after treatment with NGF were est...
objective: insomnia is accompanied by several health complications and the currently used soporific drugs can induce several side effects such as psychomotor impairment, amnesia, and tolerance. the present study was planned to investigate the sleep prolonging effect of pinus eldarica. materials and methods: hydroalcoholic extract (hae) of p. eldarica, its water fraction (wf), ethyl acetate frac...
Xylaria nigripes ( XN) is a medicinal fungus that was used traditionally as a diuretic, nerve tonic, and for treating insomnia and trauma. In this study, we elucidated possible mechanisms of neuroprotective effects of XN mycelia extracts. XN mycelia were produced by fermentation. Hot water extract and 70% ethanol extract of XN mycelia were evaluated on hydrogen peroxide (H2O2)-induced apoptosis...
The expression of the neural cell adhesion molecule, N-CAM, was examined in the anterior lobe of rat hypophysis by immunocytochemistry at light and electron microscope levels. In addition, N-CAM antigenic determinants present in adrenal medulla, anterior hypophysis and PC12 cells were compared by immunoblotting with those found in cerebellum. All secretory cells in the anterior hypophysis were ...
Objective(s): The role of aluminum (Al) in the pathogenesis of neurodegenerative diseases has been implicated in several studies. However, the exact mechanisms of cytotoxic effects of Al have not been elucidated yet. The aim of this study was to investigate the effect of L-type calcium channel antagonist, nimodipine (NM), and lithium chloride (LiCl) on Al-induced toxicity in PC12 cells. Materia...
Controlling nerve cells to form pre-designed 3D neural networks that recapitulate the intricate interconnectivity in brain is essential for developing neuronal interfaces and new regeneration approaches. Here, within biomaterials are dynamically localized using nano-based magnetic manipulations. Nerve transformed into units their organizational layout manipulated external field gradients. Iron ...
Advances in the generation of suitable thermosensitive hydrogels for the delivery of cells in neural tissue engineering demonstrate a delicate relationship between physical properties and capabilities to promote cell proliferation and differentiation. To improve the properties of these materials, it is possible to add liposomes for the controlled release of bioactive elements, which in turn can...
Though nanomaterials are considered as drug carriers or imaging reagents targeting the central nervous system their cytotoxicity effect on neuronal cells has not been well studied. In this study, we treated PC12 cells, a model neuronal cell line, with a nanomaterial that is widely accepted for medical use, superparamagnetic iron oxide nanoparticles (SPIONs). Our results suggest that, after trea...
