Deficiencies in Complex I have been observed in Parkinson's disease (PD) patients. Systemic exposure to rotenone, a Complex I inhibitor, has been shown to lead to selective dopaminergic cell death in vivo and toxicity in many in vitro models, including dopaminergic cell cultures. However, it remains unclear why rotenone seems to affect dopaminergic cells more adversely. Therefore, the role of d...

A nerve growth factor (NGF) receptor interactive monoclonal antibody (192-IgG) which enhances beta-NGF binding to PC12 cells has been produced. The hybridoma clone was obtained by fusing Sp2/0- Ag14 myeloma cells with splenocytes from Balb/C mice which had been immunized with n-octyl glucoside solubilized proteins from isolated PC12 cell plasma membranes. The antibody is an IgG, which does not ...

Doxorubicin (DOX) is a potent, broad-spectrum chemotherapeutic drug used for treatment of several types of cancers. Despite its effectiveness, it has a wide range of toxic side effects, many of which most likely result from its inherent prooxidant activity. It has been reported that DOX has toxic effects on normal tissues, including brain tissue. In the current study, we investigated the protec...

Application of nanotechnology in medicinal and biological fields has attracted a great interest in the recent yeras. In this paper the cell membrane leakage induced by iron nanoparticles (Fe-NP) against PC12 cell line which is known as a model of nervous system cell line was investigated by the lactate dehydrogenase (LDH) test. Therefore, PC12 cells were incubated with different concentration o...

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...

Cellular attachment plays a vital role in the differentiation of pheochromocytoma (PC12) cells. PC12 cells are noradrenergic clonal cells isolated from the adrenal medulla of Rattus norvegicus and studied extensively as they have the ability to differentiate into sympathetic neuron-like cells. The effect of several experimental parameters including (i) the concentration of nerve growth factor (...

Dopaminergic PC12 cells can synthesize and release dopamine, providing a good cellular model for investigating dopamine regulation. Optogenetic stimulation of channelrhodopsin-2 provides high spatial and temporal precision for selective stimulation as a powerful neuromodulation tool for neuroscience studies. The aim of this study is to measure dopamine release from dopaminergic PC12 cells under...

Glutathione (GSH) depletion has been an important contributor to the dysfunction of dopamine neurons. Polyamidoamine-GSH (PAMAM-GSH) was synthesized and the delivery effect of GSH into PC12 cells was tested. MTT assessment for cytotoxicity and reactive oxygen species (ROS) as well as nitrite oxide (NO) and intracelluar superoxide dismutase (SOD) detection for antioxidative ability were performe...

We have identified a unique heparan sulfate (HeS) proteoglycan synthesized by the neuronal-like cell line PC12. The proteoglycan, purified with monoclonal antibodies from medium conditioned by PC12 cells, has an apparent molecular weight of 350,000, and it contains a Mr 80,000 core protein and HeS side chains of Mr 15,000 each. The purified molecule has the same apparent size and density as it ...
