Book Description
The peroxiredoxin family was discovered approximately 30 years ago and is now recognized as one of the most important families of enzymes related to antioxidant defense and cellular signaling. Peroxiredoxin 6 shares the basic enzymatic functions that characterize this family, but also exhibits several unique and crucial activities. These include the ability to reduce phospholipid hydroperoxides, phospholipase A2 activity, and an acyl transferase activity that is important in phospholipid remodeling. This book describes the available models for investigating the unique functions of PRDX6 and its role in normal physiological function, as well its roles in the pathophysiology of diseases including cancer, diseases of the eye, and male fertility.

Encyclopedia of Signaling Molecules
Author: Sangdun Choi
Publisher: Springer
ISBN: 9781441904607
Category : Medical
Languages : en
Pages : 0
Book Description
Biological processes are driven by complex systems of functionally interacting signaling molecules. Thus, understanding signaling molecules is essential to explain normal or pathological biological phenomena. A large body of clinical and experimental data has been accumulated over these years, albeit in fragmented state. Hence, systems biological approaches concomitant with the understanding of each molecule are ideal to delineate signaling networks/pathways involved in the biologically important processes. The control of these signaling pathways will enrich our healthier life. Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities. This encyclopedia presents 350 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world’s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alike During past years, there were multiple databases to gather this information briefly and very partially. Amidst the excitement of these findings, one of the great scientific tasks of the coming century is to bring all the useful information into a place. Such an approach is arduous but at the end will infuse the lacunas and considerably be a streamline in the understanding of vibrant signaling networks. Based on this easy-approach, we can build up more complicated biological systems.

Antioxidants and Antioxidant Enzymes in Higher Plants
Author: Dharmendra K. Gupta
Publisher: Springer
ISBN: 3319750887
Category : Science
Languages : en
Pages : 306
Book Description
This book provides an overview of antioxidants and antioxidant enzymes and their role in the mechanisms of signaling and cellular tolerance under stress in plant systems. Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors. Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology.

Biology of Brain Disorders
Author: Daniela Tropea
Publisher: Frontiers Media SA
ISBN: 2889453804
Category :
Languages : en
Pages : 586
Book Description
Brain disorders, including neurological and neuropsychiatric conditions, represent a challenge for public health systems and society at large. The limited knowledge of their biology hampers the development of diagnostic tools and effective therapeutics. A clear understanding of the mechanisms that underlie the onset and progression of brain disorders is required in order to identify new avenues for therapeutic intervention. Overlapping genetic risk factors across different brain disorders suggest common linkages and pathophysiological mechanisms that underlie brain disorders. Methodological and technological advances are leading to new insights that go beyond traditional hypotheses. Taking account of underlying molecular, cellular and systems biology underlying brain function will play an important role in the classification of brain disorders in future. In this Research Topic, the latest advances in our understanding of biological mechanisms across different brain disorders are presented. The areas covered include developments in neurogenetics, epigenetics, plasticity, glial cell biology, neuroimmune interactions and new technologies associated with the study of brain function. Examples of how understanding of biological mechanisms are translating into research strategies that aim to advance diagnoses and treatment of brain disorders are discussed.

Genomic and Biochemical Characterisation of the B'/PR61 Regulatory Subunit Family of Protein Phosphatase 2A
Author: Ellen Martens
Publisher: Leuven University Press
ISBN: 9789058673787
Category : Science
Languages : en
Pages : 154
Book Description
"This is a Ph.D. dissertation. Reversible protein phosphorylation has become widely recognized as the most important reaction for the regulation of protein functioning in eukaryotic cells, being involved in switching cellular activities from one state to another and, in this way, regulating different cellular functions. It is the major mechanism by which cells respond to extracellular signals, such as hormones and growth factors, and control all events at various stages of the cell cycle, as well as the response of the cell to environmental and nutritional stresses. As much as one-third of cellular proteins have been estimated to undergo reversible protein phosphorylation, underlining the importance, and widespread occurrence of this modification. Contents include: General Introduction, Protein Phosphates, Multimetric Structure of PP2A, PP2A as a Kinase Phosphate, Aims of the Work, Materials and Methods, Results, B'/PR61-Interacting Proteins, Discussion."
