PURPOSE Malignant pheochromocytoma (PCC) is a rare tumor with a very poor prognosis and no effective treatments. The aim of this study was to assess the efficacy of a novel second-generation synthetic heat-shock protein 90 (HSP90) inhibitor, NVP-AUY922, to treat malignant PCC in vitro and in vivo. MATERIALS AND METHODS Cell Counting Kit-8 (CCK-8) and Transwell assays were used to assess the e...
Materials and methods Our work aimed to evaluate the antioxidant activity, protective properties and anti-proliferative capacity of Lycium europeaum and Jatropha podagrica extracts on the proliferation and evolution of A547 (ovarian cancer cell line), OVCAR-3 (human ovary adenocarcinoma cell line), A549 (Human lung adenocarcinoma cell line) and PC12 (rat adrenal medulla Pheochromocytoma cells)....
Retinoic acid (RA) induced neuronal differentiation in A126-1B2 cells and 123.7 cells, two mutant lines of PC12 that are deficient in cAMP-dependent protein kinase, but not in the parental PC12 cell line. A single exposure to RA was sufficient to cause neurite formation and inhibit cell division for a period of greater than 3 wk, suggesting that RA may cause a long-term, stable change in the st...
Tyrosine hydroxylase (TH), the rate-limiting enzyme in catecholamine synthesis, is stimulated by N-terminal phosphorylation on its regulatory domain and inhibited by protein serine/threonine phosphatase 2A (PP2A). PP2A comprising of an AC core dimer composed of catalytic (C) and scaffolding (A) subunit is complexed to a variable regulatory subunit derived from three gene families (B, B’, B”). M...
the influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. this study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (olhe). olive leaves were collected from gardens around the city of shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. the influ...
background: rna interference (rnai) is the mechanism of gene silencing-mediated messenger rna degradation by small interference rna (sirna), which becomes a powerful tool for in vivo research, especially in the areas of cancer. in this research, the potential use of an expression vector as a specific sirna producing tool for silencing of bcr-abl in k562 cell line has been investigated. methods:...
expression of receptor tyrosine kinase ror1 in a wide variety of cancers has emerged as a new era focusing on targeting this receptor in cancer therapy. our preliminary re-sults indicate the presence of a truncated transcript of ror1 in tumor cells. the trun-cated ror1 encompasses extracellular and transmembrane domains, lacking catalytic kinase domain (ror1-ecd). as enzyme activity is highly d...
We first examined the involvement of the complex sphingolipids in cell-substratum adhesion using GM-95, a mutant cell line deficient in glycosphingolipids (GSLs) due to the lack of ceramide glucosyltransferase activity. We determined the adhesion of the mutant cells and stable transfectants expressing GSLs, which were established by transfection of GlcT-1 cDNA into GM-95 cells under neutral sph...
To examine the role of Ca2+/calmodulin-dependent protein kinase II (CaMKII) in cell differentiation and neuronal functions, stable transformants of PC12 cells were established that expressed levels of the alpha-subunit of CaMKII (alpha CaMKII) equivalent to mammalian neurons. The expression of the transfected alpha CaMKII gene or the endogenous beta CaMKII gene was monitored by RNase protection...
Persistent stimulation of specific protein kinase pathways has been proposed as a key feature of receptor tyrosine kinases and intracellular oncoproteins that signal neuronal differentiation of rat pheochromocytoma (PC12) cells. Among the protein serine/threonine kinases identified to date, the p42/44 mitogen-activated protein (MAP) kinases have been highlighted for their potential role in sign...
