The aim of this work was to compare protective and anti-apoptotic effects of α-tocopherol at nanomolar and micromolar concentrations against 0.2 mM H(2)O(2)-induced toxicity in the PC12 neuronal cell line and to reveal protein kinases that contribute to α-tocopherol protective action. The protection by 100 nM α-tocopherol against H(2)O(2)-induced PC12 cell death was pronounced if the time of pr...
The effects of pertussis toxin, an uncoupler of Gi protein from adenylate cyclase, and luzindole, a competitive inhibitor of melatonin receptor binding, were examined for their ability to inhibit melatonin-induced suppression of PC12 cell growth. Both agents inhibited the melatonin response suggesting that melatonin may be acting through one of its Gi coupled cell surface receptors. This is con...
background: most cancer cells become resistant to anti-cancer agents. in the last few years, a new approach for targeted therapy of human cancer has been developed using immunotoxins which comprise both the cell targeting and the cell killing moieties. methods: in the present study, the recombinant shiga toxin a1 subunit fused to human granulocyte-macrophage colony stimulating factor (a1-gm-csf...
in this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in iran. the cells were originating from two-day-old normal male calf of holstein breed. the cell cultures were continuously passaged following complete proliferation of primary cells. the specific properties or characteristics of the cell were defined using cytogene...
Estrogen alters neurite outgrowth, neuritic spine development, and synaptogenesis in estrogen-responsive areas of the rat brain. However, examination of the specific effects of estrogen on neurons in vivo has been difficult. An in vitro model for the effects of estrogen on neurons was developed, using the PC12 rat pheochromocytoma cell line. Wild-type cells (PC12-WT) were stably transfected eit...
The three alpha(2)-adrenergic receptor subtypes have distinct tissue distributions, desensitization properties, and, in some cell types, subtype-specific subcellular localization and trafficking properties. The subtypes also differ in their neuronal physiology. Therefore, we have investigated the localization and targeting of human alpha(2)-adrenoceptors (alpha(2)-AR) in PC12 cells, which were ...
The rat pheochromocytoma PC12 cell line differentiates into a sympathetic neuronal phenotype upon treatment with either nerve growth factor (NGF) or basic fibroblast growth factor. The alkaloid-like compound K-252a has been demonstrated to be a specific inhibitor of NGF-induced biological responses in PC12 cells (Koizumi, S., Contreras, M. L., Matsuda, Y., Hama, T., Lazarovici, P., and Guroff, ...
Nerve growth factor (NGF) causes pheochromocytoma cells (PC12) to undergo a number of physiological changes which mimic the differentiated neuronal cell, including neurite extension. We have examined protein kinase C (Ca2+/phospholipid-dependent enzyme) as a potential signaling mechanism in NGF-stimulated neurite outgrowth and induction of the enzyme ornithine decarboxylase. Phorbol 12-myristat...
The presence of unique proteins in synaptic vesicles of neurons suggests selective targeting during vesicle formation. Endocrine, but not other cells, also express synaptic vesicle membrane proteins and target them selectively to small intracellular vesicles. We show that the rat pheochromocytoma cell line, PC12, has a population of small vesicles with sedimentation and density properties very ...
background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...
