Gant dc269 инструкция
Human hepatoma cells Hep G2initially isolated from a liver biopsy Gant dc269 инструкция a y-old Caucasian male 27were obtained from the American Type Culture Collection ATCC, Rockville, MD. RNA transfer was confirmed by visualization of ethidium bromide—stained RNA under UV light.
The secondary antibody was designed to have minimal cross-reactivity with human serum proteins produced by Hep G2 cells. Cells were then rinsed Gant dc269 инструкция PBS and mounted onto microscope slides as previously described. For photomicrographs, exposure times were held constant to permit comparisons among treatment groups. Isolation of nuclear extracts. Cytoplasmic and nuclear proteins were separated following a modification of previously described procedures In two separate experiments, cells were grown in 75 mm2 flasks.
Thus, this study was designed to test the hypothesis Gant dc269 инструкция copper-induced hepatocyte apoptosis is mediated largely by post-transcriptional mechanisms involving Gant dc269 инструкция Furthermore, given that copper Gant dc269 инструкция has been associated with tumorigenesis, this study also examined the possible regulation of hepatocyte apoptosis and p53 regulation by copper deficiency.
Autoradiography detected a single band with an approximate molecular weight of 45 kDa. Densitometry was Gant dc269 инструкция as previously described to determine relative abundance of p53 in cytosolic and nuclear fractions.
The serum protein ceruloplasmin, which has ferrioxidase activity and is essential for normal iron metabolism, is also dependent on the presence of copper 6. Because of the requirement for copper in these and other enzymes, deficiency symptoms including anemia, neutropenia, cardiovascular abnormalities and neurodegeneration have been reported 78 Although the essentiality of copper has been well documented, copper is also known to be a toxic metal.
Copper treatment increased cellular copper from 0. TEPA treatment did not alter cellular zinc concentrations. The control zinc concentration was 3.
Nuclei were examined and photographed using a Nikon Microphot-FX equipped with epifluorescence. This antibody was designed to permit detection of both wild-type and mutant p An additional antibody, Gant dc269 инструкция to detect the presence of p53 in the mutant conformation, was also used Pab, Santa Cruz Biotechnologies in separate dishes.
Untreated cells served as controls. The supernatant fraction containing cytoplasmic proteins was collected and concentrated. The Gant dc269 инструкция containing nuclear proteins was collected and concentrated. Total protein concentration for Gant dc269 инструкция cytosolic and nuclear fractions was determined using the bicinchoninic acid method Pierce, Rockford, IL.
Copper toxicity can be caused by a mutation in the gene that codes for a copper-transporting P-type ATPase 1011 In humans with WD, hepatic copper can be between 5 and 8 times greater than normal 15, Copper poisoning can lead to copper toxicity The resulting tissue damage is particularly pronounced in the liver where copper accumulation can lead to hepatitis, cholagiofibrosis, cirrhosis and hepatocellular carcinoma 13,171819 Copper overload can result in apoptotic cell death 2122 Gant dc269 инструкция, The mechanisms responsible for copper regulation of pmediated death are not known, but it would be reasonable to hypothesize that they would include an increase in p53 mRNA because other hepatotoxic treatments have been shown to significantly increase p53 gene transcription 24, However, only a small twofold increase in p53 mRNA in LEC rat liver relative to Gant dc269 инструкция Sprague-Dawley control rats has been reported 26suggesting that other mechanisms may be involved.
Relative amounts of bound cDNA probe were determined by computer evaluated Gant dc269 инструкция Quantity One Quantification created by Protein and DNA Imaging PDI, Boston, MA and expressed as a function of GAPDH mRNA abundance. Cellular and nuclear morphology. Nuclear staining of cells fixed to coverslips was used to examine the nuclei of cells Cells were washed 3 times in PBS pH 7. Washington, PA in PBS for 10 min. Cells were then permeabilized with 0.
