Buch. Zustand: Neu. Neuware - Intracellular cell signaling is a well understood process. However, extracellular signals such as hormones, adipokines, cytokines and neurotransmitters are just as important but have been largely ignored in other works. They are causative agents for diseases including hypertension, diabetes, heart disease, and arthritis so offer new, and often more approachable, targets for drug design. Aimed at medical professionals and pharmaceutical specialists, this book integrates extracellular and intracellular signalling processes and offers a fresh perspective on new drug targets. Written by colleagues at the same institution, but with contributions from leading international authorities, it is the result of close cooperation between the authors of different chapters. Readers are introduced to a new approach to disease causation by adipokines and toxic lipids. Heart disease, migraines, stroke, Alzheimer's disease, diabetes, cancer, and arthritis are approached from the perspective of prevention and treatment by alteration of extracellular signalling. Evidence is presented that the avoidance of toxic lifestyles can reduce the incidence of such illnesses and new therapeutic targets involving adipokines, ceramide and endocannabinoids are discussed.

Buch. Zustand: Neu. Neuware - This book is the first example in presenting LC-MS strategies for the analysis of peptides and proteins with detailed information and hints about the needs and problems described from experts on-the-job. The best advantage is -for sure- the practical insight of experienced analysts into their novel protein analysis techniques. Readers starting in 'Proteomics' should be able to repeat each experiment with own equipment and own protein samples, like clean-up, direct protein analysis, after (online) digest, with modifications and others. Furthermore, the reader will learn more about strategies in protein analysis, like quantitative analysis, industrial standards, functional analysis and more.

Buch. Zustand: Neu. Neuware - G protein-coupled receptors (GPCRs) constitute the largest family of cell-surface receptors, with more than 800 members identified thus far in the human genome. They regulate the function of most cells in the body, and represent approximately 3% of the genes in the human genome. These receptors respond to a wide variety of structurally diverse ligands, ranging from small molecules, such as biogenic amines, nucleotides and ions, to lipids, peptides, proteins and even light. Ligands (agonists and antagonists) acting on GPCRs are important commonly used in drug therapy of numerous diseases, including cardiovascular and mental disorders, retinal degeneration, cancer, and AIDS. It is estimated that these receptors represent about one third of the actual identified targets of clinically used drugs. This book, which lies between the fields of chemical biology, molecular pharmacology and medicinal chemistry, is divided into three parts. The first part considers what receptor structures tell us about the mechanism of receptor activation. Part II focuses on receptor function. It discusses what the data from biophysical and mutational studies, and the analysis of the interactions of the receptor with ligands and regulator proteins, tell us about the process of signal transduction. The final part, on modelling and simulation, details what new insights on the link between structure and mechanism can be provided by theoretical studies and their implications in drug design. The various chapters present an update on the latest developments in GPCR structures and detailed structural changes linked to activation. They cover the latest news of the extraordinary complex function of these receptors, concentrating on the many aspects that are currently revolutionizing our current views of these proteins: receptor constitutive activity, receptor oligomerization, functional selectivity, biased agonism, multiple signalling pathways, multiple accessory proteins, functional cross talk and the mechanism of signal integration. This complex picture is tackled from complementary experimental and theoretical approaches, which represent a clear statement of our current knowledge of the GPCR complexity.
