The most fundamental question facing each and every cell within an org- ism is to survive or to die. Cell death is required for normal function; some estimates suggest that as many as one million cells undergo cell death every second in the adult human body. Almost all cells undergoing physiological, or programmed, cell death, independent of cell type, manifest a stereotypic p- tern of morphological changes termed apoptosis. Typically, apoptotic cells d- play shrinkage, membrane blebbing, chromatin condensation, and nuclear fragmentation. The integrity of the cell membrane is not lost during apoptosis and so avoids eliciting the inflammatory response that would have been caused by the spillage of the cell´s contents. This is quite in contrast to the loss of cell contents typical of necrosis. The caspases, the family of intracellular cysteine proteases associated with apoptosis, are responsible for the stereotypical m- phological changes. Caspases cleave various substrate proteins that act on DNA fragmentation, nuclear envelope integrity, the cytoskeleton, and cell volume regulation. Apoptotic cells are cleared in vivo by the process of phagocytosis, in which specific ´´phagocytes´´ move to the site of apoptosis, engulf the dying cells and digest them. Apoptosis has a central role in many physiological processes, for example, in the immune system. Autoreactive cells are deleted via apoptosis to prevent autoimmunity. At the end of an immune response, activated lymphocytes are removed to maintain homeostasis within the immune system.

[SR: 4887043], Hardcover, [EAN: 9780896038738], Humana Press, Humana Press, Book, [PU: Humana Press], Humana Press, A collection of cutting-edge techniques for detecting and quantifying apoptosis, understanding its biochemistry, and for identifying the genes and proteins that regulate and carry it out. Described in step-by-step detail, these readily reproducible methods range from flow cytometry and immunohistochemical procedures to kinase activity assays, yeast two-hybrid screening, and the cloning of novel genes by differential expression. The protocols follow the successful Methods in Molecular Biology™ series format, each one offering step-by-step laboratory instructions, an introduction outlining the principle behind the technique, lists of equipment and reagents, and tips on troubleshooting and avoiding known pitfalls. Apoptosis Methods and Protocols constitutes a key technical reference to the significant methodologies used in the field, as well as offering novice and experienced researchers alike powerful tools to illuminate the phenomenon of programmed cell de, 13524, Cell Biology, 226688, Biology, 13469, Biological Sciences, 75, Science & Math, 1000, Subjects, 283155, Books, 13540, Molecular Biology, 226688, Biology, 13469, Biological Sciences, 75, Science & Math, 1000, Subjects, 283155, Books, 684289011, Biology, 491702, Biology & Life Sciences, 468216, Science & Mathematics, 465600, New, Used & Rental Textbooks, 2349030011, Specialty Boutique, 283155, Books<
