The role of protein kinase A in regulating transcription of the cholinergic gene locus, which contains both the vesicular acetylcholine transporter gene and the choline acetyltransferase gene, was investigated in PC12 cells and a protein kinase A-deficient PC12 mutant, A126.1B2, in which transcription of the gene is reduced. The site of action of protein kinase A was localized to a neuron-restr...
MicroRNAs are involved in regulation of the central nervous system (CNS) development, and miR-181d highly expressed mature neurons. CREB is many signal pathways converged point hippocampal neurons, it plays a crucial role learning memory. In this study, we detected negative relationship between CREB1 protein expression lewis rat hippocampus development. And bioinformatic analysis showed that, m...
PC12 cells differentiate in response to nerve growth factor from a chromaffin cell to a sympathetic neuronal phenotype. Wnt-1 is a secreted signaling factor required for development of mammalian midbrain and cerebellum. PC12 cells transformed by Wnt-1 fail to express several differentiation-specific genes in response to nerve growth factor. We have previously shown that HES-1, a negative regula...
BACKGROUND Parkinson's disease (PD) is the second most common neurodegenerative disease, affecting 2% of the population aged over 65 years old. Mitochondrial defects and oxidative stress actively participate in degeneration of dopaminergic (DA) neurons in PD. Paeonolum, a main component isolated from Moutan cortex, has potent antioxidant ability. Here, we have examined the effects of paeonolum ...
Cells of the rat neuronal line, PC12, adhere well to substrates coated with laminin and type IV collagen, but attach poorly to fibronectin. Adhesion and neurite extension in response to these extracellular matrix proteins are inhibited by Fab fragments of an antiserum (anti-ECMR) that recognizes PC12 cell surface integrin subunits of Mr 120,000, 140,000, and 180,000 (Tomaselli, K. J., C. H. Dam...
To assess a possible role for the Src homology 2 (SH2) domain adaptor protein Shb in PC12 cell signal transduction and differentiation, we have investigated the expression of Shb in PC12 cells and found that the differentiation factors nerve growth factor (NGF) and basic fibroblast growth factor (bFGF), as well as the PC12 cell mitogen epidermal growth factor, increased Shb protein expression a...
Background: Acrylamide (ACR) is a well-known industrial toxic chemical that produces neurotoxicity, which is characterized by progressive central and peripheral neuronal degeneration. Chrysin is a natural, biologically active flavonoid compound, which is commonly found in many plants. The antioxidant and neuroprotective properties of chrysin have been demonstrated. Methods: In this study, the ...
BACKGROUND Aberrant α-synuclein aggregation due to the deficiency of ubiquitin-proteasome or of autophagy characterizes the parkinson disease (PD). High mobility group box 1 (HMGB1) is a novel stress sensor to mediate the persistent neuro-inflammation and the consequent progressive neurodegeneration, via controlling the cellular autophagy/apoptosis checkpoint during inflammation. Moreover, HMGB...
The rat adrenal pheochromocytoma PC12 cell line is one of the traditional models for the study of neurite outgrowth and growth cone behavior. To clarify to what extent PC12 neurite terminals can be compared to neuronal growth cones, we have analyzed their morphology and protein distribution in fixed PC12 cells by immunocytochemistry. Our results show that that PC12 cells display a special kind ...
Glucose-regulated protein 75 (Grp75), also known as mortalin/mthsp70/PBP74, is a member of the heat-shock protein 70 (HSP70) family. Grp75 is known to protect cells from stress-induced injury. Previous studies have shown that the expression of Grp75 is upregulated by a low dose of ionizing radiation (IR). To evaluate the protective role of Grp75 o...
