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...
Neurite outgrowth is essential for the communication of the nervous system. The rat Pheochromocytoma (PC12) cells are commonly used in the neuronal cell study. It is well known that exogenous stimuli such as Nerve Growth Factor (NGF) induce neurite outgrowth. In the present study it has been investigated whether or not the conditioned medium from human neuroblastoma cell line (IMR-32) and human...
Objective(s): This study was designed to indicate whether different fractions from Artemisia biennis hydroethanolic extract could provide cytoprotection against oxidative stress and apoptosis induced by doxorubicin (DOX) in rat pheochromocytoma cell line (PC12). Material and Methods:Cell viability was determined by MTT assay. Also, activation of caspase-3 and superoxide dismutase were evaluated...
To study the processing of secretogranin II (SgII) by the prohormone convertase PC2 we have generated a stable PC12 cell line which expresses mouse PC2. We here present the characteristics of the PC12/PC2 cell line and demonstrate that the exogenous PC2 is sorted and stored in secretory granules in the PC12/PC2 cell line as efficiently as the endogenous granins. By indirect immunofluorescence w...
Acid-sensing ion channels (ASICs) are expressed in various sensory and central neurons. The functional role of these channels remains elusive. Complex subunit combinations and lack of specific blockers for native receptors are likely to contribute to the difficulty of resolving the function of ASICs. Finding a neuronal cell line, which expresses a single population of ASICs, should prove to be ...
Neuronal nitric oxide synthase (nNOS) neurons kill adjacent neurons through the action of NMDA-glutamate receptor activation, although they remain relatively resistant to the toxic effects of NMDA and NO. The molecular basis of the resistance of nNOS neurons to toxic insults is unknown. To begin to understand the molecular mechanisms of the resistance of nNOS neurons, we developed a pheochromac...
Background: Mellitus (DM). The exact mechanisms of diabetic neurotoxicity are still unknown. Recently oxidativestress is introduced as one of the factors for diabetics’ neuropathies. Antioxidants also used astherapeutic agents to reduce the side effects of diabetes. In the present research the antioxidant effectsof total and flavonoid extracts of Cusseta lehmaniana Bunge on high glucose inducte...
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 M~ 120,000, 140,000, and 180,000 (Tomaselli, K. J., C. H. Dam...
It has been reported that organic cation/carnitine transporter 1 (OCTN1) is associated with rheumatoid arthritis and Crohn's disease. Additionally, we reported that OCTN1 is expressed in hematopoietic cells, and is associated with proliferation and differentiation of erythroid cells. However, physiological role of OCTN1 is still unclear. Ergothioneine, an anti-oxidant, was recently reported to ...
