Biological functions are almost exclusively attributed to macromolecules, i.e. nucleic acids, proteins and polysaccharides. To gain their complete functional activities these biomolecules have to associate with the nuclear matrix, the cytoskeleton and the cell/plasma membranes. It is the aim of this series to discuss actual aspects in the field of structure-associated genetic and epigenetic functional processes. This series of survey reviews fills the gap in structure-associated information flow, and is a vital reference work for scientists in molecular and cell biology.

Biological functions are almost exclusively attributed to macromolecules, such as nucleic acids, proteins and polysaccharides. To gain their complete functional activities these biomolecules have to associate with the cellular components, such as the nuclear matrix, cytoskeleton or cell/plasma membranes. Topics discussed in this volume 12 include the synthesis of small nuclear RNAs, DNA-activated protein kinase, interactions of water and proteins in cellular functions, heat-shock protein synthesis and the cytoskeleton during early development.
Molecular and Cellular Enzymology
第 13 本图书 · 2012年12月 ·
0.0
Proteins constitute the working-class molecules of the cell. Hence, understanding the way they act is a prerequisite for understanding how a cell functions and how life evolves. Aspects such as the protein-ligand relationship, recognition, protein evolution by point mutation, enzyme-substrate interactions, behaviour of an enzyme in a living cell, control and dynamics of enzyme networks as well as the physico-chemical background of enzyme actions and multi-enzyme complexes are comprehensively treated in this volume.
Biological Response Modifiers — Interferons, Double-Stranded RNA and 2′,5′-Oligoadenylates
第 14 本图书 · 2012年12月 ·

Biological response modifiers are increasingly used in viral and cancer therapy. Since alterations of the immune system are the primary symptoms of HIV infection, especially therapies directed towards the modulation of the immune response have been under intense evaluation. This volume summarizes current knowledge of the interferon-based natural antiviral protection system including 2',5'-oligoadenylate and double-stranded RNA. It will also help to develop further a solid scientific rationale for the practical use of heterologous immunomodulators in the clinics.
Invertebrate Immunology

The biological bases of invertebrate immune responses have interested scientists for decades, from the first relevant observation by E. Metchnikoff in 1882, who discovered phagocytosis while studying starfish larvae. Invertebrate immunology first began to be appre ciated as an important field in the late 1960s and 1970s. However, in the following years there was much controversy regarding the question: do invertebrates offer insight into the origin of the sophisticated immune responses of the vertebrates? There are several reasons why progress in research on invertebrate immune competence has been painfully slow. One of the main impediments to the progress, as compared to the fast development of knowledge in the vertebrate systems, was the fact that most of the studies concentrated on "whole organism" assays, mainly on grafting tissues between allogeneic partners. Only in the last few years have more and more aspects of invertebrate immunity been investigated on the cellular, biochemical and molecular levels. These studies led to discoveries of novel defense reactions, new pathways of effector mechanisms which are elicited after recognition of "nonself', and complex, sometimes highly polymorphic genetic elements that control invertebrate immune reactions. The importance of invertebrate immunity for understanding "immunology" as a whole, despite the conflicting models and hypotheses, is now much more recognized than before. Although most of the 20 phyla belonging to the inver tebrates have different modes of life, body organizations, habitats occupied, and biochemical patterns, they show striking aspects of exceptional precision for discriminating between self and nonself.
Apoptosis

Apoptosis plays a central role in the regulation of cell proliferation. Disruption of this control mechanism may cause serious human diseases such as encephalomyelitis and cancer. Thus, understanding of the molecular mechanisms of apoptotic cell death should lead to fundamental advances in the therapy of these diseases.
Signaling Mechanisms in Protozoa and Invertebrates

Comparative endocrinology helps to find the roots of homeostatic regulation in organisms. In this context, many years ago a series of experiments were done, which demonstrated the hormonal regula tion also on the invertebrate level. The mechanisms are partly similar, partly different, from those found in vertebrates. The new receptor era of mammalian endocrinology stimulated research on invertebrate hormone receptors, and sophisticated methods are applied also to determine hormones. The experiments demonstrated the existence and even similar function of these structures and signaling molecules. However, data on hormones and receptors at the lowest level of metazoan life and the highest level of protozoan life were not at our disposal. About two decades ago, first observations on the presence of hormone receptors reacting to vertebrate hormones in protozoa were made. Since the early 1980s we know that hormone-like molecules similar to those of higher vertebrates are present also in unicellular organisms. The presence of some second messengers in Tetrahymena was recognized. Since then, the research has been extended and many structures - previously believed to be solely vertebrate characteristics, such as opiate receptors, similar to mammalian ones - were found in unicellular organisms. These observations justified the assumption of a complete endocrine system at protozoan level, where - considering the unicellularit- this seemed to be not required. However, it became clear that the roots of endocrine communication date back at least 2 billion years.
Cytoplasmic fate of messenger RNA
第 18 本图书 · 2012年12月 ·

Among all cellular RNA species of the three main types, ribosomal RNA, transfer RNA or messenger RNA, be they from prokaryotic or eukaryotic organisms, the prokaryotic mRNA is unique in that it has no precursor and is synthesized in the same mature form as it is translated into proteins. In fact, ribosomes join the nascent mRNA chain and engage in protein synthesis long before its transcription is complete. Provisions are even made for slowing down the ribo somes at some sites to prevent them from catching up with the RNA-polymerase. Of course, such a situation is only possible in the prokaryotic world where there is no such thing as a nuclear mem brane physically secluding the transcription process from the cy toplasm where translation is restricted. Quite in the opposite extreme, the eukaryotic pre-messenger RNA has to suffer many and sometimes drastic steps of maturation (capping, polyadenylation, splicing, edition) before the decision is made to export it to the cytoplasm. That is where it enters the scope of this book. Once in the cytoplasm, many options are still open to it: its entrance into polysomes may be delayed (as it is in unfertilized eggs) or merely prohibited (ferritin mRNA in iron-starved cells), directed to specific locations within the cytoplasm or be more or less rapidly degraded. During gametogenesis and early development, translational control is probably the most significant level of gene expression.
Molecular Evolution: Evidence for Monophyly of Metazoa
第 19 本图书 · 2012年12月 ·
0.0
This volume concentrates on the origin of multicellular animals, Metazoa. Until now, no unequivocal phylogeny has been produced. Therefore, the questions remain: Did Metazoa evolve from the Protozoa only once, or several times? Is the origin of animals monophyletic or polyphyletic? Especially the relationships between the existing lower metazoan phyla, particularly the Porifera (sponges) are uncertain. Based on sequence data of genes typical for multicellularity it is demonstrated that all Metazoa, including Porifera, should be placed into the kingdom Animalia together with the Eumetazoa. Therefore it is most likely that all animals are of monophyletic origin.
Inhibitors of Cell Growth
第 20 本图书 · 2012年12月 ·

The containment of cell growth is at the core of the homeostatic regulation of metazoans, and considerable progress has been made in the understanding of how this is achieved. Most knowledge comes from the isolation of molecu les with positive and negative regulatory effects on cell proliferation, and most emphasis so far has been on these molecules. Some of these molecules are already available for therapeutic purposes, and others look promising in this respect. This volume gives examples of such approaches. The understanding of the control of cell growth is also fundamental to grasp phylogenic and ontogenic development. Why organisms have developed increasingly sophisticated mechanisms that control their size and that of their organs, how different cells originate, some destined for renewal and repair, others for specialized functions in a postmitotic state or evolving through division, others like the germinal cells waiting for the signal to start another organism. There is one mechanism of growth containment, however, about which we know very little. It concerns the structural characteristics of the cell, i.e. the relationship between structure and function. How structure can change the response to identical signals. The positive and negative growth regulators may be conserved, but the structure and organization of the genetic material and of other cell components differ widely and are responsible to a great extent for the differences in cell proliferative behaviour.
