Protein Transfer and Organelle Biogenesis is a seven-section volume focusing on the property of proteins to carry signals for secretion, mitochondrial assembly, and lysosomal localizations. It describes how these signals function and determines other factors necessary in building and maintaining the functions of a cell. Organized into seven sections encompassing 19 chapters, the book deals with the general aspects of protein translocation, modification, and sorting. It discusses the transport into the endoplasmic reticulum, the role of carbohydrates in glycoprotein trafficking, and the mechanism of endo- and exocytosis. It further discusses the localization of proteins to the mitochondrion and nucleus and with bacterial protein transport. The final section emphasizes the contribution secretion research that the biotechnology industry has made to the production of proteins. Biologists, cell biologists, researchers, teachers, and students who are interested in the mechanism of protein transfer and organelle biogenesis will find this book invaluable.

Scientific reviews are now of two complementary types: short, very up-to-date articles, as are found in the Trends series, and the more traditional longer re views, which are more comprehensive but take longer to publish. The Subcellu lar Biochemistry series belongs to the latter category where a number of reviews on a broad topic are collected together in the one volume. It has been the aim of this volume to summarize the present state of knowledge of membrane assembly. It is appreciated that some relevant topics have not been included, and an editor's selection is restricted by the many calls on potential authors who are unable to meet all requests made to them. The absence of a discussion of the roles of lipids is," however, a reflection of the fact that a recent volume in this series, edited by Dr. H. 1. Hilderson, has been devoted to this subject (Vol. 16, Intracellular Transfer of Lipid Molecules), and readers are recommended to this source.

The compartmentation of genetic information is a fundamental feature of the eukaryotic cell. The metabolic capacity of a eukaryotic (plant) cell and the steps leading to it are overwhelmingly an endeavour of a joint genetic cooperation between nucleus/cytosol, plastids, and mitochondria. Alter ation of the genetic material in anyone of these compartments or exchange of organelles between species can seriously affect harmoniously balanced growth of an organism. Although the biological significance of this genetic design has been vividly evident since the discovery of non-Mendelian inheritance by Baur and Correns at the beginning of this century, and became indisputable in principle after Renner's work on interspecific nuclear/plastid hybrids (summarized in his classical article in 1934), studies on the genetics of organelles have long suffered from the lack of respectabil ity. Non-Mendelian inheritance was considered a research sideline~ifnot a freak~by most geneticists, which becomes evident when one consults common textbooks. For instance, these have usually impeccable accounts of photosynthetic and respiratory energy conversion in chloroplasts and mitochondria, of metabolism and global circulation of the biological key elements C, N, and S, as well as of the organization, maintenance, and function of nuclear genetic information. In contrast, the heredity and molecular biology of organelles are generally treated as an adjunct, and neither goes as far as to describe the impact of the integrated genetic system.

As the amount of information in biology expands dramatically, it becomes increasingly important for textbooks to distill the vast amount of scientific knowledge into concise principles and enduring concepts.As with previous editions, Molecular Biology of the Cell, Sixth Edition accomplishes this goal with clear writing and beautiful illustrations. The Sixth Edition has been extensively revised and updated with the latest research in the field of cell biology, and it provides an exceptional framework for teaching and learning. The entire illustration program has been greatly enhanced.Protein structures better illustrate structure–function relationships, icons are simpler and more consistent within and between chapters, and micrographs have been refreshed and updated with newer, clearer, or better images. As a new feature, each chapter now contains intriguing openended questions highlighting “What We Don’t Know,” introducing students to challenging areas of future research. Updated end-of-chapter problems reflect new research discussed in the text, and these problems have been expanded to all chapters by adding questions on developmental biology, tissues and stem cells, pathogens, and the immune system.

This book provides information on the molecular interactions between host cell organelles and pathogens, which have developed strategies to survive within infected cells. Chapters are grouped into five sections: I. Endocytosis and phagocytosis. Collectively, the chapters of this section review basic knowledge regarding intracellular organelles are involved in membrane interactions with pathogen-containing vacuoles. II. Professional and non-professional phagocytes. Here the authors describe the major differences between the two host cell types, which can be infected by microorganisms. III. Maturation pathways of bacteria-containing vacuoles. Molecular interactions between vacuoles and intracellular organelles leading to the search of the Holy Grail, the replication niche, are described. IV. Host response. Host cells are able to react against intruders and eventually mount host responses. In these chapters the various types of host response mechanisms against intracellular intruders are reviewed. V. Co-evolution. In these final chapters, the question is addressed of whether knowledge of bacteria-host cell interactions will be acquired fast enough to find the necessary tools for controlling microorganism development.

Processing and Turnover of Proteins and Organelles in the Cell is a collection of papers that tackles the problems of post-translational processes, along with the dynamics of cell components. The materials in the title are organized thematically. The text first presents articles dealing with post-translational processing, such as the mode of anchoring of sucrase-isomaltase to the small intestinal brush-border membrane and its biosynthetic implications, as well as the decay and restoring in succinate dehydrogenase. The next papers discuss topics related to the selective degradation of proteins, such as selective control of proteinase action in yeast cells and studies of the mechanism and selectivity of intracellular protein breakdown. The final set of papers covers the turnover of organelles, which includes biogenesis and turnover of peroxisomes, and the effect of oxygen on the synthesis of mitochondrial proteins in Saccharomyces cerevisiae. The book will be of great use to microbiologists and biochemists. Scientists from biological science disciplines will also benefit from the text.

Molecular Mechanisms and Physiological Significance of Organelle Interactions and Cooperation

Eukaryotic cells contain distinct membrane-bound organelles, which compartmentalise cellular proteins to fulfil a variety of vital functions. Many organelles have long been regarded as isolated and static entities (e.g., peroxisomes, mitochondria, lipid droplets), but it is now evident that they display dynamic changes, interact with each other, share certain proteins and show metabolic cooperation and cross-talk. Despite great advances in the identification and characterisation of essential components and molecular mechanisms associated with the biogenesis and function of organelles, information on how organelles interact and are incorporated into metabolic pathways and signaling networks is just beginning to emerge. Organelle cooperation requires sophisticated targeting systems which regulate the proper distribution of shared proteins to more than one organelle. Organelle motility and membrane remodeling support organelle interaction and contact. This contact can be mediated by membrane proteins residing on different organelles which can serve as molecular tethers to physically link different organelles together. They can also contribute to the exchange of metabolites and ions, or act in the assembly of signaling platforms. In this regard organelle communication events have been associated with important cellular functions such as apoptosis, antiviral defense, organelle division/biogenesis, ROS metabolism and signaling, and various metabolic pathways such as breakdown of fatty acids or cholesterol biosynthesis. In this research topic we will focus on recent novel findings on the underlying molecular mechanisms and physiological significance of organelle interaction and cooperation with a particular focus on mitochondria, peroxisomes, endoplasmic reticulum, lysosomes and lipid droplets and their impact on the regulation of cellular homeostasis. Our understanding of how organelles physically interact and use cellular signaling systems to coordinate functional networks between each other is still in its infancy. Nevertheless recent discoveries of defined membrane structures such as the mitochondria-ER associated membranes (MAM) are revealing how membrane domains enriched in specific proteins transmit signals across organelle boundaries, allowing one organelle to influence the function of another. In addition to its role as a mediator between mitochondria and the ER, contacts between the MAM and peroxisomes contribute to antiviral signaling, and specialised regions of the ER are supposed to initiate peroxisome biogenesis, whereas intimate contacts between peroxisomes, lipid droplets and the ER mediate lipid metabolism. In line with these observations it is tempting to speculate that further physical contact sites between other organelles exist. Alternatively, novel regulated vesicle trafficking pathways between organelles (e.g., mitochondria to peroxisomes or lysosomes) have been discovered implying another mode of organelle communication. Identifying the key molecular players of such specialised membrane structures will be a prerequisite to understand how organelle communication is physically accomplished and will lead to the identification of new regulatory networks. In addition to the direct transmission of interorganellar information, cytosolic messenger systems (e.g., kinase/phosphatase systems or redox signaling) may contribute to the coordination of organelle functions. This research topic will integrate new findings from both modes of communication and will provide new perspectives for the functional significance of cross-talk among organelles. We would like to thank all the researchers who contributed their valuable work to this research topic. Furthermore, we are grateful to the reviewers and Associate Editors who contributed valuable comments and positive criticism to improve the contributions.
