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...
To elucidate physiological and clinical implications of the natriuretic peptide family, the expression of receptors for natriuretic peptides has been examined in cultured cells (a rat pheochromocytoma cell line [PC12], bovine endothelial cells, rat aortic smooth muscle cells, human mesangial cells, and a porcine kidney epithelial cell line [LLC-PK1]) by Northern blot analysis and cyclic GMP pro...
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...

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).

Oxidative stress and apoptosis contribute to neuronal degeneration in many neurodegenerative diseases such as Alzheimer's disease. Glutamate is a major excitatory neurotransmitter in the central nervous system (CNS) and is considered responsible for the pathogenesis of many neurological disorders. Reactive oxygen species (ROS) production is thought to be involved in glutamate-induced apoptosis ...
Methylmercury (MeHg)-resistant sublines of rat pheochromocytoma (PC12) cells were isolated by repeated exposure to stepwise increased concentrations of MeHg. One of the sublines (PC12/TM) showed an 8- to 10-fold increase in resistance to MeHg compared with parent PC12 cells on the basis of the concentration required for 50% inhibition (IC50) of growth. PC12/TM cells accumulated smaller amounts ...
When the sympathetic nerve-like cell line PC12 is exposed to nerve growth factor (NGF), there is a rapid and transient phosphorylation of tyrosine residues in cellular proteins, as demonstrated by immunoblotting of cell extracts with high-affinity polyclonal antibodies specific for phosphotyrosine residues. Epidermal growth factor (EGF), which does not cause the morphological differentiation of...
shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...
زمینه و هدف: ساخت و ترکیب داروهای جدید گیاهی و شیمیایی علیه بیماری هایی مثل سرطان، از جمله تلاش های مهم سال های اخیر محسوب می شود. ترکیبات ترپنی از جمله ترکیبات مهمی هستند که خواص بیولوژیکی و فارماکولوژیکی متعددی دارند، اما به دلیل حلالیت کم آن ها در محلول های آبی کمتر مورد توجه بوده اند. سیکلودکسترین ها نیز نانوکپسول های طبیعی تشکیل شده از واحدهای گلوکزی هستند که می توانند ایجاد نانوحفره نماین...
Objective: Oxidative stress is associated with the pathogenesis of brain ischemia and other neurodegenerative disorders. Previous researches have shown the antioxidant activity of Viola odorata L. In this project, we studied neuro-protective and reactive oxygen species (ROS) scavenging activities of methanol (MeOH) extract and other fractions isolated from <e...
