background: considering that cannabinoids protect neurons against neurodegeneration, in this study, the neuroprotective effect of win55,212-2 in paraoxon induced neurotoxicity in pc12 cells and the role of the n-methyl-d-aspartate (nmda) receptor were evaluated. materials and methods: in this study pc12 cells were maintained in dulbecco's modified eagle’s medium (dmem+f12) culture medium supple...

We investigate the mechanical response of PC12 neurites subjected to a drag force imposed by a laminar flow perpendicular to the neurite axis. The curvature of the catenary shape acquired by an initially straight neurite under the action of the drag force provides information on both elongation and tension of the neurite. This method allows us to measure the rest tension and viscoelastic parame...

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...

Objective(s): Recent studies revealed that microRNAs (miRNAs) may play crucial roles in the responses and pathologic processes of spinal cord injury (SCI). This study aimed to investigate the effect and the molecular basis of miR-103 on LPS-induced injuries in PC12 cells in vitro and SCI rats in vivo. Materials and Methods: PC12 cells were exposed to LPS to induce cell injuries to mimic the in ...

Background and Aims:In neurodegenerative disorders,oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages which can lead to apoptosis. Pro-apoptotic and anti-apoptotic gene expressions are changed during the cell differentiation that affect cell viability and differentiation. Therefore, this study was conducted to determine the effects of hyd...

Background: Aluminum (Al) exposure is among the environmental risk factors that may involve in the pathogenesis of neurodegenerative diseases. Oxidative stress has a critical role in the Al-induced toxicity. Saffron is a plant with potent radical scavenging and anti-oxidative properties. This investigation was designed to evaluate the possible protective effects of saffron extract (SE) on alumi...

The protective effect of a L-type calcium channel blocker, nimodipine, on cell injury induced by oxygen-glucose deprivation (OGD) in PC12 cells was investigated. PC12 cells were exposed to in-vitro oxygen-glucose deprivation (30 minutes and 60 minutes respectively) in the presence or absence of nimodipine (10mM/L) in three different time schedules (pre-24h, pre-3h and concurrently). Cellular vi...

Cells of the rat neuronal line, PC12, adhere well to substrates coated with laminin and type IV collagen, but attach poorly to fibronectin. Adhesion and neurite extension in response to these extracellular matrix proteins are inhibited by Fab fragments of an antiserum (anti-ECMR) that recognizes PC12 cell surface integrin subunits of Mr 120,000, 140,000, and 180,000 (Tomaselli, K. J., C. H. Dam...

background and objective: in neurodegenerative disorders, oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages that lead to apoptosis. pro-apoptotic and anti-apoptotic gene expressions were changed during cell differentiation that affect cell viability and differentiation. this study was conducted to determine the effects of hydrogen peroxi...
