Neuritogenesis and the nerve growth factor-induced differentiation of PC-12 cells requires annexin II-mediated plasmin generation.

One of the key morphological changes associated with the nerve growth factor (NGF)-induced differentiation of rat adrenal pheochromocytoma (PC-12) cells is the growth of axon-like processes called neurites. A growing body of evidence suggests that this process may be dependent upon plasmin, a serine protease generated from plasminogen (Plg) by either urokinase Plg activator (u-PA) or tissue Plg...

Nerve growth factor-induced neuronal differentiation requires generation of Rac1-regulated reactive oxygen species.

Nerve growth factor (NGF) stimulation of pheochromocytoma PC12 cells transiently increased the intracellular concentration of reactive oxygen species (ROS). This increase was blocked by the chemical antioxidant N-acetylcysteine and a flavoprotein inhibitor, diphenylene iodonium. NGF responses of PC12 cells, including neurite outgrowth, tyrosine phosphorylation, and AP-1 activation, was inhibite...

K-252a: a specific inhibitor of the action of nerve growth factor on PC 12 cells.

K-252a, a kinase inhibitor isolated from the culture broth of Nocardiopsis sp., selectively inhibits the actions of nerve growth factor (NGF) on PC 12 cells. At a concentration of 200 nM, K-252a prevents neurite generation initiated by NGF, but not neurite generation produced by fibroblast growth factor or outgrowth produced by dibutyryl cAMP. K-252a also inhibits the induction of ornithine dec...

Nerve Growth Factor and the Trans-differentiation of Human Dental Pulp Stem Cells Into Cholinergic-like Neurons

Introduction: Cell therapy has been widely considered as a therapeutic approach for neurodegenerative diseases and nervous system damage. Cholinergic neurons as one of the most important neurons that play a significant role in controlling emotions, mobility, and autonomic systems. In this study, human dental pulp stem cells (hDPSCs) were differentiated into the cholinergic neurons by β-mercapto...

Transcriptional and post-transcriptional effects of nerve growth factor on expression of the three neurofilament subunits in PC-12 cells.

Nerve growth factor (NGF) is known to increase the levels of neurofilament proteins in PC-12 pheochromocytoma cells. In this report, we show that the three neurofilament subunits, NF-L, NF-M, and NF-H, are not induced coordinately. NF-H accumulated only after longer term NGF treatment than required for NF-L and NF-M. While NGF treatment resulted in 12- and 14-fold increases in NF-L and NF-M mRN...
