Integrins are well characterized cell surface receptors for extracellular matrix proteins. Mapping integrin-binding sites within the fibrillar collagens identified GFOGER as a high affinity site recognized by α2β1, but with lower affinity for α1β1. Here, to identify specific ligands for α1β1, we examined binding of the recombinant human α1 I domain, the rat pheochromocytoma cell line (PC12), an...
We have previously described the isolation of a clonal cell line (PC-G2) in which the level of tyrosine hydroxylase (TH), the rate-limiting step in the synthesis of the catecholamine neurotransmitters, is induced by nerve growth factor (NGF). We now report that epidermal growth factor (EGF) also induces TH in the PC-G2 cell line. Although EGF has been shown to be mitogenic for many cultured cel...
Objective: Sleep disorders are among the most common psychiatric and medical conditions. In the present study, the hypnotic effect of Tanacetum parthenium was studied in mice. Material and Methods: The hydro-alcoholic extract (HAE) of T. parthenium and three fractions of it, namely water fraction (WF), ethyl acetate fra...
Exposure to ethanol for several days increases the number and function of dihydropyridine-sensitive Ca2+ channels in excitable tissues. In the neural cell line PC12, this process is blocked by inhibitors of protein kinase C (PKC), suggesting that PKC mediates ethanol-induced increases in Ca2+ channels. We report that treatment with 25-200 mM ethanol for 2-8 days increased PKC activity in PC12 c...
Formation of functional N-methyl-D-aspartate (NMDA) receptor channels requires the essential NMDA receptor subunit NR1 and one or more of the modulatory subunits NR2A-D and in some cases an additional subunit NR3A or NR3B. Recent studies indicate that NR1 expression is regulated at translation under both physiological and pathological conditions. The rat pheochromocytoma cell line (PC12) has be...
introduction: g-proteins have an important role in the cell signaling of numerous receptors. the situation of g-proteins in health and disease and their critical role in the development of diabetic side effects is an interested scientific field. here, the changes in the expression of g-protein subunits (gαi, gαs and gβ) were evaluated in hyperglycemic situation of pc12 cells as a cellular model...
the anti-cancer activity of metal ions in the lanthanide group is being considered recently. it has been reported that cerium salts might stimulate the metabolism and therefore, produce anti-cancer effects. however, little is known about the effects of protein-cerium complex in controlling cancer cell growth. the aim of the present study was to elucidate the possible pathways for the cytotoxic ...
Huntington's disease is a progressive neurodegenerative disorder caused by a polyglutamine expansion near the N-terminus of huntingtin. The mechanisms of polyglutamine neurotoxicity, and cellular responses are not fully understood. We have studied gene expression profiles by short oligo array using an inducible PC12 cell model expressing an N-terminal huntingtin fragment with expanded polygluta...
A 57 kDa protein is the major polypeptide in intermediate filament (IF)-enriched cytoskeletal preparations obtained from the neuronal cell line PC12 (rat pheochromocytoma). Under the conditions used to assemble IF in vitro from other cultured cell lines, 10 nm filaments are formed after 2 cycles of disassembly-assembly from PC12 IF-enriched cytoskeletal preparations; the 57 kDa protein is the m...
