objective (s):hyperglycemia is widely recognized as the underlying cause for some debilitating conditions in diabetic patients. the role of cannabinoid cb1 and vanilloid trpv1 receptors and their endogenous agonists, endovanilloids, in diabetic neuropathy is shown in many studies. here we have used pc12 cell line to investigate the possible influence of glucose concentration in culture medium o...

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...

introduction: g-proteins have an important role in the cell signaling of numerous receptors. the situation of g-proteins in health and disease and their critical role in the development of diabetic side effects is an interested scientific field. here, the changes in the expression of g-protein subunits (gαi, gαs and gβ) were evaluated in hyperglycemic situation of pc12 cells as a cellular model...

Introduction: The Serum/Glucose deprivation -induced cell death in cultured PC12 cells represents a useful in vitro model for the study of brain ischemia and neurodegenerative disorders. Nigella sativa L. has been known as a source of antioxidants. To elucidate the neuroprotective actions of N. sativa extract in vitro, we studied the effect of N. sativa extract on cultured PC12 cells under s...

luteolin, as a natural polyphenolic compound, has neuroprotective effect and exerts its function by attenuation of apoptosis and oxidative stress factors. emerging evidences indicate that oxidative stress leads to neurodegeneration but is not the initial event and endoplasmic reticulum stress (er) is often considered to be the stimulus event which is caused by accumulating of misfolded proteins...
