introduction: increased oxidative stress is widely accepted to be a factor in the development and progression of alzheimer’s disease. triazine derivatives possess a wide range of pharmacological activities including anti-oxidative and anti-in.ammatory actions. in this study, we aimed to investigate the possible protective effect of 3-thioethyl-5,6-dimethoxyphenyl-1,2,4-triazine (tedmt) on h2o2-...
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...
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...
Cytosolic phospholipase A2 (cPLA2) preferentially liberates arachidonic acid (AA), which is known to be elevated in Alzheimer's disease (AD). The aim of this study was to investigate the possible relationship between enhanced nitric oxide (NO) generation observed in AD and cPLA2 protein level, phosphorylation, and AA release in rat pheochromocytoma cell lines (PC12) differing in amyloid beta se...
Cell damage induced by free radicals has been implicated as causal factor in a wide variety of human diseases such as cancer, neurodegenerative disorders. Scientific recognition of natural antioxidants may be helpful in preventing many diseases. Aqueous Date fruit extract (ADFE)- PC12 cell line. ADFE at concentrations of 0.1-10% containing 0.005% H2O2 and H2O2 at concentrations of 0.01-1% conta...
Objective(s): Hyperglycemia, oxidative stress and apoptosis have key roles in pathogenesis of diabetic neuropathy. There are local renin-angiotensin systems (RASs) in different tissues such as neural tissue. Local RASs are involved in physiological and pathophysiological processes such as inflammation, proliferation and apoptosis. This study aimed to investigate the role of local renin-angioten...
Cytosolic phospholipase A2 (cPLA2) preferentially liberates arachidonic acid (AA), which is known to be elevated in Alzheimer’s disease (AD). The aim of this study was to investigate the possible relationship between enhanced nitric oxide (NO) generation observed in AD and cPLA2 protein level, phosphorylation, and AA release in rat pheochromocytoma cell lines (PC12) differing in amyloid beta se...
Background and objectives: Neuronal toxicity can be induced by oxidative stress via free radicals production. In recent years, great interest has been expressed to the traditional and herbal medicines. The purpose of this study was to elucidate the neuroprotective activity of Leontice leontopetalum methanol extract against H2O2-stimulated oxidative stress in PC12 cells...
The mechanical response of PC12 neurites under tension is investigated using a microneedle technique. Elastic response, viscoelastic relaxation, and active contraction are observed. The mechanical model proposed by Dennerll et al. [J. Cell Biol. 109, 3073 (1989).10.1083/jcb.109.6.3073], which involves three mechanical devices--a stiff spring kappa coupled with a Voigt element that includes a le...
Background and Objective: Biomaterials and nanomaterials have generated a great opportunity in regenerative medicine. Neurological disorders can result in permanent and severe derangement in motor and sensory functions. This study was conducted to examine the effects of selenium nanoparticles (Se NPs) as a chemical inducer for differentiation of PC12 cells into sympathetic-like neurons characte...
