Mitotic Spindle Proteomics in Chinese Hamster Ovary Cells
Mitosis is a fundamental process in the development of all organisms. The mitotic spindle guides the cell through mitosis as it mediates the segregation of chromosomes, the orientation of the cleavage furrow, and the progression of cell division. Birth defects and tissue-specific cancers often result from abnormalities in mitotic events. Here, we report a proteomic study of the mitotic spindle ...
متن کاملPolyclonal antibody-mediated mitotic inhibition in Chinese hamster ovary cells.
The nucleus of a mammalian cell undergoes profound reorganization when the cell enters mitosis and a number of proteins involved at various levels of the cell cycle have been characterized. The presence of mitotic-specific proteins has been reported and their roles are important in understanding the mechanics of cell division. The ability of antibodies to recognize mitotic protein antigens and ...
متن کاملEXPRESSION OF HUMAN PROTEINASE 3 IN CHINESE HAMSTER OVARY CELLS (CHO-CELLS)
Proteinase 3(PR3) is a human polymorphonuclear leukocyte serine proteinase and is the main target antigen for antineutrophil cytoplasmic antibodies (ANCA) found in Wegener's granulomatosis (WG). We developed a stable expression system for conformationally intact recombinant PR3 (rPR3) in Chinese hamster ovary cells (CHO-cells). The part of PR3 cDNA that encoded the active form of PR3 was s...
متن کاملIntracellular Localization of FLAG-Peroxisomal Protein in Chinese Hamster Ovary (CHO) Cells
Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...
متن کاملDistribution of pericentriolar material in multipolar spindles induced by colcemid treatment in Chinese hamster ovary cells.
Mitotic Chinese hamster ovary cells were obtained by treatment with microtubule drugs under various conditions, and the shape of spindles was analysed by phase-contrast microscopy of isolated spindles, and by indirect immunofluorescence staining of whole mitotic cells with anti-tubulin antibody. Bipolarity of spindles was maintained after treatment with 0.05 microM of colcemid for 3.5 h, but in...
