Molecular regulation of neuronal apoptosis in PC12 cells.
In this study apoptosis was induced in neuronal PC12 cells by 2-5 $\mu$M VM26 (teniposide, a known apoptotic inducer) and changes in the expression of genes considered to be involved in apoptosis were examined by RT-PCR. Cell death, DNA fragmentation and morphological changes associated with …

NADPH oxidase in PC12 cell differentiation and apoptosis
… the common factor leading to neuronal death. PC12 cells differentiate into sympathetic-like neurons in the presence of nerve growth factor (NGF). Once terminally differentiated, PC12 cells undergo apoptosis following NGF deprivation with similar characteristics of sympathetic neuronal death. …

Regulation of n-3 PUFA biosynthesis in proliferating and differentiated PC12 pheochromocytoma cells
… in proliferating and NGF-differentiated PC12 pheochromocytoma cells deficient in n-3 docosahexaenoic acid (DHA, 22:6n- 3) was studied. A dose- and time dependent increase in eicosapentaenoic acid (EPA, 20:5n-3), docosapentaenoic acid (DPA, 22:5n-3) and DHA in phosphatidylethanolamine …

The crosstalk between the ERK and the cAMP signalling pathways in PC12 Cells
… survival, proliferation and differentiation. In PC12 cells, the ERK signalling pathway integrates different external stimuli: epidermal growth factor (EGF) stimulates the ERK pathway transiently and induces cell proliferation, whereas nerve growth factor (NGF) induces sustained activation of ERK …

Type I PIP5Kα negatively regulates NGF-induced neurite outgrowth in PC12 cells
… outgrowth. For this, I generated a stable PC12 cell line lacking PIP5KIa by microRNA (miRNA) expression, leading to decreased PtdIns(4,5)P2 level. Results show that neurite outgrowth induced by nerve growth factor (NGF) was more prominent in PIP5KIa-deficient cells than in control …

Effects of nerve growth factor on TGF-Beta,Smad signal transduction in PC12 cells
… is characterized in rat pheochromocytoma cells (PC12) which are frequently used as a model system for neuronal differentiation. PC12 cells were found to be unresponsive to TGF-ß due to limiting levels of TßRII. However, stimulation with NGF results in initiation of Smad-mediated transcription …

The establishment and characterization of an improved cell-free assay for exocytosis in neuroendocrine PC12 cells
… beschichteten Objektträgern wachsende PC12-Zellen wurden durch einen Ultraschallpuls in einer kleinen Kammer direkt auf dem Objekttisch eines Fluoreszenzmikroskops aufgeschlossen. Durch Ca2+ konnten eGFP-beladenen Vesikel der so hergestellten "membrane lawns" zur Exozytose und damit zur …

Pheochromocytoma-induced cardiomyopathy : a model of synergistic effects of multifactorial tumor secretions
… a polymeric cell encapsulation system to control PC12 cell kinetics and NE release in vitro and in vivo. We demonstrated that pheochromocytoma-conditioned media induced greater cardiomyocyte contractility and cytoskeletal remodeling than NE alone. We next examined the cardiomyopathy development in …

Expression and Requirement of Epithelial Fatty Acid- Binding Protein in Neuronal Axon Growth
… test this hypothesis, E-FABP expression in both PC12 cells and primary retinal neurons was examined. In PC12 cells, NGF induces E-FABP mRNA and protein during the period of neurite outgrowth, and E-FABP localizes to the perinuclear cytoplasm, nucleus, and growth cone. Furthermore, …

Effects of tumor necrosis factor alpha on nitric oxide synthase in nerve growth factor-responding cells
… oxide synthase (NOS), in rat pheochromocytoma PC12 cells. NGF/TNFa-promoted iNOS can be toxic in PC12 cells. Using PC12 cell mutants lacking the low affinity p75NTR receptor, we also demonstrate that this receptor is required to mediate iNOS expression, likely acting through the transcription …

MacMARCKS and the Protein Kinase C Signal Transduction Pathway: Role in Neural Secretion and Neural Development
… manner in rat brain synaptosomes and PC12 cells. It is localized to cell bodies and neurite tips of PC12 cells as well as being present on synaptic vesicles. A dominant-negative mutation in the MacMARCKS effector domain which abolishes PKC-dependent phosphorylation is associated with …

Zinc ion homeostasis in cellular physiology and experimental models of traumatic brain injury
… and differentiated rat pheochromocytoma (PC12) cells and in rat glioma (C6) cells. When PC12 cells proliferate, [Zn2+]i undergoes precisely controlled fluctuations with two peaks within one cell cycle. These results demonstrate that the already established requirement for zinc in the cell …

COMBINATORIAL DEVELOPMENT OF NANOSTRUCTURED MATERIAL LIBRARIES FOR THE STUDY OF CELL SUBSTRATE INTERACTION
… was investigated by contact angle measurements. PC12 cells derived from a Pheochromocytoma of the rat adrenal medulla were cultured on five different morphologies in presence of nerve growth factor (NGF) and the results suggest that the increasing roughness not only diminishes cellular attachment …

Neuroprotective Effects of FGF20 on Dopamine Neurones
… ERK1/2 activation and neurite outgrowth in PC12 cells. It was demonstrated here that agrin potentiates FGF20 stimulated ERK1/2 activation, but it fails to potentiate FGF20’s neuroprotective effects in PC12 cells.

Halting the neural progression of cancer
… vitro, SEMA3F-induced repulsion was observed in PC12 and U87MG cells, which express NRP2. SEMA3A also successfully repelled SY5Y cells, which express NRP1. Neurite length was significantly inhibited by SEMA3F in PC12 and U87MG neurite outgrowth assays. Taken together, our results suggest that …

Newly Synthesized Pyroglutamate Amide and its Neuroprotective Effect Against Neurotoxicity Induced Cell Death in Alzheimer's Disease
… NSP has more potent effect in inhibiting N2a and PC12 cells than the potent effect of mem due to the amide function in NSP. We also demonstrate that NSP has an inhibitory effect at a great extent on glutamate induced N2a and PC12 cells death. The inhibition of the activity of glutamate was shown …
