Download or read book Structural and Functional Studies of the Human Apoptosome written by Shujun Yuan and published by . This book was released on 2009 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: NOD (nucleotide binding and oligomerization domain) proteins are a subclass of the AAA+ ATPases (ATPases associated with various cellular activities), which play important roles in apoptosis and innate immune response. Apaf-1 is a founding member of the NOD family, which regulates apoptosis in mammalian cells. In the presence of cytochrome c and dATP/ATP, Apaf-1 oligomerizes to form the human apoptosome, which binds and activates procaspase-9 (pc-9) to initiate a proteolytic cascade. The domain structure of the human apoptosome has been determined previously by electron microscopy and individual domain modeling, but some aspects of this model remain unclear. To obtain a higher resolution structure and understand the interaction between the apoptosome and pc-9, we constructed a pc-9 mutant, which has a thrombin site in the linker region between the pc-9 prodomain and catalytic domains. After holo-apoptosome assembly, thrombin released the pc-9 catalytic domains, and apoptosomes with bound pc-9 prodomains were used for structural studies. We determined a high resolution structure of this "activated" apoptosome at - 9 A resolution by electron microscopy and single particle methods, and built a pseudo-atomic model, which revealed new aspects of apoptosome assembly and activation. First, CARDs (caspase activation and recruitment domains) are flexible in the ground state apoptosome. Second, pc-9 prodomains interact with Apaf-1 CARDs to form an "activation" disk that sits above the stable, heptameric platform. This disk is flexibly attached through short linkers to the NBDs (nucleotide binding domains). Finally, the pc-9 catalytic domains are flexible and do not interact with the apoptosome during their activation. Instead, our data support an "in cis" activation model, based on quantitative mass spectrometry, mutagenesis of the pc-9 linker and pc-9 activity assays. In this model, pc-9 monomers on the apoptosome are activated by dimerization with a neighboring pc-9. The flexibly linked pc-9 dimers may create an optimal procaspase-3 processing machine.

Download or read book Cell Death written by Hao Wu and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning from centuries of anecdotal descriptions of cell death, such as those on the development of the midwife toad in 1842 by Carl Vogt, to modern-day investigations of cell death as a biological discipline, it has become accepted that cell death in multicellular organisms is a normal part of life. This book provides a comprehensive view of cell death, from its mechanisms of initiation and execution, to its implication in human disease and therapy. Physiological cell death plays critical roles in almost all aspects of biology, and the book details its roles in lymphocyte homeostasis, neuronal function, metabolism, and the DNA damage response. When physiological cell death goes awry, diseases can arise, and cancer is presented as a central paradigm for the consequences of derangements in the interplay between cell survival and cell death. At the same time, the potential promise of targeted therapies aimed at interdicting cell death machineries are also discussed extensively. The molecular mechanisms that underlie apoptotic cell death are illustrated from the perspectives of both the intrinsic, mitochondrial apoptotic pathway and the extrinsic, death receptor pathway. Key players in these pathways, such as the Bcl2 family proteins, cytochrome c, Apaf-1, caspases, death receptor adapter proteins, and inhibitor of apoptosis proteins, are presented from both functional and structural angles. Until only a few years ago, programmed cell death has been considered essentially synonymous with apoptosis. However, we now know that programmed cell death can also take other forms such as necrosis or necroptosis, and to this end, the mechanisms that underlie programmed necrosis in development and host defense are illustrated. The past twenty plus years have seen an incredible growth of research in cell death, with one breakthrough after another, and the legacy still goes on with constant new surprises and findings. Long live cell death!

Download or read book Neuronal Death by Accident or by Design written by C.E. Henderson and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four chapters represent the intense current effort to understand the way in which the mitochondrion controls the activation of the final stages of cell death. Another four articles attack the problem from the other side. How do specific insults in particular human or mouse neuro-degenerative diseases translate into mechanisms that will not only allow us to better understand what is happening in these patients but also, with luck, allow for development of more efficient and specific drugs in the future? Firstly, the concept of a central common cell death pathway, originally derived from studies on the nematode, has been an outstanding productive paradigm in bringing together different strands of research. Secondly, truly striking links have been made between results obtained in the culture dish (or even cell-free systems) and the diseased human brain.

Download or read book Mechanistic Insights Into Apoptosome Dependent Caspase 9 Processing and Activation written by Srinivas Malladi and published by . This book was released on 2010 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: During stress-induced apoptosis, the initiator caspase-9 is activated by the Apaf-1 apoptosome and must remain bound in order to retain significant catalytic activity. Nevertheless, in apoptotic cells, the vast majority of processed caspase-9 is paradoxically observed outside of the complex. We demonstrate herein that apoptosome-mediated cleavage of procaspase-9 occurs exclusively through a CARD-displacement mechanism, so that unlike the effector procaspase-3, procaspase-9 cannot be processed by the apoptosome as a typical substrate. Indeed, procaspase-9 possessed higher affinity for the apoptosome and could displace processed caspase-9 from the complex, thereby facilitating a continuous cycle of procaspase-9 recruitment/activation, processing, and release from the complex. Due to its rapid autocatalytic cleavage, however, procaspase-9 per se contributed little to the activation of procaspase-3. Thus, the Apaf-1 apoptosome functions as a proteolytic-based "molecular timer", wherein the intracellular concentration of procaspase-9 sets the overall duration of the timer, procaspase-9 autoprocessing activates the timer, and the rate at which processed caspase-9 dissociates from the complex (and thus loses its capacity to activate procaspase-3) dictates how fast the timer "ticks" over. To understand the physiological relevance of molecular timer in vivo, we are currently generating caspase-9 knock-in mouse models. These mouse models will enhance our understanding of the importance of caspase-9 processing within the apoptosome.

Download or read book Cell Death in Mammalian Ovary written by Gerardo H. Vázquez-Nin and published by Springer Science & Business Media. This book was released on 2011-05-26 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ovary is a suitable organ for studying the processes of cell death. Cell death was first described in the rabbit ovary (Graaffian follicles), the phenomenon being called ‘chromatolysis’. To date, it is recognized that various forms of cell death (programmed cell death, apoptosis and autophagy) are essential components of ovarian development and function. Programmed cell death is responsable for the ovarian endowment of primordial follicles around birth; in the prepuberal and adult period, apoptosis is a basic mechanism by which oocytes are eliminated by cancer therapies and environmental toxicants; in the ovarian cycle, follicular atresia and luteal regression involve follicular cell apoptosis. Finally, abnormalities in cell death processes may lead to ovarian disease such as cancer and chemoresistance. In this book, after an introductory description of various forms of cell death and of the ovary development and function in mammals, the processes of cell death in ovarian somatic cells and oocytes are described at cytological, physiological and molecular levels and analyzed in the embryonic, prepuberal and adult ovary. A complex array of molecular pathways triggered by extrinsic and intrinsic signals able tor induce or suppress cell death in the same cell, according to cell type and ovary developmental stage, emerges. Physiological interactions with the axis hypothalamus-hypophysis as well as ovarian internal functional signal are also critically reviewed to explain the abortive development of follicles before the beginning of the ovarian cycle. The book conveys information useful to the updating of biologists and physicians who are interested to the ovary biology and functions. Hopefully it should provide also clues for stimulating novel experiments in the study of cell death in the mammalian ovary still at an early stage.
