Previous studies have shown that in neuronal cells the developmental phenomenon of programmed cell death is an active process, requiring synthesis of both RNA and protein. This presumably reflects a requirement for novel gene products to effect cell death. It is shown here that the death of nerve growth factor-deprived neuronal PC12 cells occurs at the same rate as that of rat sympathetic neuro...
The beta-amyloid protein, the major component of the vascular and plaque amyloid deposits that characterize Alzheimer's disease, derives from a larger beta-amyloid precursor protein (APP) that is expressed in both neural and nonneural cells. An increased expression of APP might actively contribute to the development of the pathology; however, the mechanisms involved in the regulation of APP gen...
The protein product of the proto-oncogene c-src is a membrane-associated tyrosine kinase of unknown function. Identification of pp60c-src target membranes may elucidate the function of the c-src protein. The available evidence indicates that pp60c-src associates with distinct membranes within single cell types and has different distributions in different cell types. Our experiments demonstrate ...
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...
The RET tyrosine kinase is a functional receptor for neurotrophic ligands of the glial cell line-derived neurotrophic factor (GDNF) family. Loss of function of RET is associated with congenital megacolon or Hirschsprung's disease, whereas germ-line point mutations causing RET activation are responsible for multiple endocrine neoplasia type 2 (MEN2A, MEN2B, and familial medullary thyroid carcino...
Glutamate is a major excitatory neurotransmitter present in the central nervous system. The glutamate/cystine antiporter system x c- connects the antioxidant defense with neurotransmission and behaviour. Overactivation of ionotropic glutamate receptors induces neuronal death, a pathway called excitotoxicity. Glutamate-induced oxidative stress is a major contributor to neurodegenerative diseases...
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): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
Objective(s): The possible action of nonsteroidal anti-inflammatory drugs (NSAIDs) in the reduction of reactive oxygen species (ROS) and also as anti-apoptotic agents may suggest them as putative agents for the treatment of neurodegenerative diseases. This study was designed to explore some pathways alterations induced by NSAIDs following 6-hydroxydopamine (6-OHDA)-ind...
Studies were undertaken to determine the effect of the Ras suppressor Rsu-1 on Ras signal transduction pathways in two different cell backgrounds. An expression vector containing the mouse rsu-1 cDNA under the control of a mouse mammary tumor virus promoter was introduced into NIH 3T3 cells and the pheochromocytoma cell line PC12. Cell lines developed in the NIH 3T3 background expressed p33rsu-...
