This book, written by members of the European network PROTEOSTASIS, provides an up-to-date review of the research regarding protein homeostasis in health and disease. With new discoveries contributing to the increasing complexity of this topic, the book offers a detailed overview of the pathways regulating protein homeostasis, including autophagy and the ubiquitin protein family. Following a basic introduction, it explains how defects in protein homeostasis contribute to numerous pathologies, including cancer, neurodegeneration, inflammation and a number of rare diseases. In addition, it discusses, the role of protein homeostasis in cellular development and physiology. Highlighting the latest research in the field of protein homeostasis and its implications for various clinically relevant diseases, the book appeals to researchers and clinicians, while also offering a reference guide for scholars who are new to the field.

Dieses Buch führt in die wichtigsten Theorien des Alterns ein; es konzentriert sich auf Telomere, DNA-Schädigung, oxidativen Stress, die Rolle der Nährstoffversorgung bzw. -erkennung, das Zusammenspiel von Genen und Umwelt (Epigenetik) und die Proteinhomöostase und stellt einige Gene vor, die die Lebensdauer in Modellorganismen zu verändern in der Lage sind. Indem es die verschiedenen das Altern bestimmenden Faktoren mit Erkrankungen des Menschen verknüpft, sucht das Buch ihre vielfältigen Wechselbeziehungen und Abhängigkeiten aufzuzeigen und zu einer molekularen Matrix des Alterns zusammenzuführen. Von diesem Buch werden alle profitieren, die sich einen profunden Überblick über die Mechanismen der Zellalterung und ihre Verknüpfung mit altersassoziierten Erkrankungen des Menschen verschaffen wollen.

Aging represents a physiological and per se non-pathological and multifactorial process involving a set of key genes and mechanisms being triggered by different endogenous and exogenous factors. Since aging is a major risk factor in connection with a variety of human disorders, it is increasingly becoming a central topic in biochemical and medical research. The plethora of theories on aging – some of which have been discussed for decades – are neither isolated nor contradictory but instead can be connected in a network of pathways and processes at the cellular and molecular levels. This book summarizes the most prominent and important approaches, focusing on telomeres, DNA damage and oxidative stress as well as on the possible role of nutrition, the interplay between genes and environment (epigenetics) and intracellular protein homeostasis and introduces some genes that have actually extended life spans in animal models. Linking these different determinants of aging with disease, this volume aims to reveal their multiple interdependencies. We see that there is no single “perfect” theory of aging and that instead it is possible to define what the authors call the molecular aging matrix of the cell. A better knowledge of its key mechanisms and the mutual connections between its components will lead to a better understanding of age-associated disorders such as Alzheimer's disease.
