Biochemistry of Human Cancer focuses on advances in the application of biochemistry to the study of human cancers, such as neoplastic immunoglobulinopathies, cancer of the bladder, tumors of the neural crest, leukemias and lymphomas, and neoplasms of the bone. It also examines certain features of human cancer ranging from general metabolic characteristics to enzymic aspects and immunochemical considerations. Organized into 18 chapters, this book begins with an overview of the general metabolic features of cancer, with emphasis on the metabolism of lipids, proteins, and carbohydrates. It then discusses the important biochemical aspects of pulmonary and prostatic neoplasms, including the serum acid and alkaline phosphatase activities of prostatic carcinoma. The remaining chapters look at the role of enzymes and immunoglobulins in cancer, the tryptophan metabolism in cancer of the bladder and the carcinoid syndrome, the link between amino acid metabolism and tumors of the neural crest, and the neoplasms of the digestive tract and the accessory organs (pancreas and liver). The book explains the metabolism of purines and pyrimidines in cancer, hypercalcemia in neoplastic disease without evidence of bone metastases, and neoplasms of other organs, such as the pituitary gland, thyroid, testis, and adrenal cortex. Brief case reports from the literature are included to illustrate correlations between biochemical and clinical findings. Scientists, biochemists, and clinical investigators concerned with the biochemistry of human cancer will find this book highly informative.

Biology of Fertilization, Volume 2: Biology of the Sperm is the second in a three-volume series that brings together various lines of research about reproduction in general and fertilization in particular. It is devoted to spermatogenesis, sperm physiology, and the initial interactions of sperm with egg components. The book is organized into three parts. Part I on spermatogenesis and sperm physiology includes studies on the evolution of the sperm cell; regulatory mechanisms, sperm antigen differentiation, and maturation of sperm in the reproductive tracts in mammals; physicochemical mechanisms of the acrosome filament extrusion process; and enzymes associated with sperm cell function. Part II deals with chemotaxis in microorganisms: bacteria and slime molds. Part III on gamete recognition and binding includes studies on identifying, isolating, and characterizing specific sperm and egg surface components involved in sperm-egg interaction; fertilization in the alga Fucus; fertilization in insects; and the role of lysins in fertilization.

The Testis: Advances in Physiology, Biochemistry, and Function, Volume IV, provides an overview of the state of knowledge in the physiology, biochemistry, and function of the testis. This volume updates those areas of greatest research activity and introduces in a more complete manner those topics which have developed as subject areas in themselves. It includes a chapter on testicular steroidogenesis, which updates and expands the chapter appearing in Volume II. In addition, chapters on the role of FSH in the testis, the specialized (largely endocrine) functions of the Sertoli cells, and the entire account of the tubular hormone inhibin have all been extensions of material in the original chapter on testicular endocrinology. Similarly, separate chapters on blood flow in the testis, fluid secretion, and the blood-testis barrier all report data on subjects largely unsuspected when Volumes I-III were published. Neither the first three volumes nor is the present one intended primarily for the nonprofessional biologist or the popular reader. The coverage should be most useful and informative to professional biologists. It is anticipated that this volume will also be of interest to advanced students of animal biology as an authoritative, comprehensive, and convenient review of significant recent information concerning the testis.

This book is a comprehensive, multi-authored work on the structure and function of the mammalian testis. The approach emphasizes gene expression, translation and production of specific gene products and the cellular and molecular regulation of these fundamental processes. Rather than provide a global survey of all aspects of male reproduction, this book stresses specific mechanisms that underscore the structure and function of the testis. It explains old and new concepts from a cellular and molecular perspective. This novel approach allows the authors to forge links between cell and molecular biology and well-established aspects of spermatogenesis and steroidogenesis. The result is a well-focused, comprehensive, and synthetic analysis of testicular biology.

Ca2+ signaling in neurons is characterized by highly restricted and dynamic gradients called Ca2+ waves, spikes, transients and puffs depending upon their corresponding spatial and temporal features. Based on this strict segmentation the Ca2+ ion provides a versatile basis for complex signaling in neuronal subcompartments with a spatial resolution of micro- and nanodomains. The multitude of Ca2+-regulated processes requires specialized downstream processing machinery, translating the Ca2+ signal into alterations of cellular processes. The broad range of different Ca2+-triggered phenomena in neurons, ranging from neurotransmission to gene expression, is reflected by the existence of a multitude of different Ca2+-binding proteins (CaBPs) from which numerous belong to the EF-hand super-family. EF-hand proteins can be subdivided into Ca2+ buffer and Ca2+ sensor proteins. Whereas the first group has a very high affinity for Ca2+, exhibits little conformational change in the Ca2+-bound state and is thought to mainly chelate Ca2+, the second group has a lower affinity for Ca2+ and shows considerable conformational changes upon Ca2+-binding, which usually triggers a target interaction. Neuronal calcium sensor (NCS) proteins and the related Caldendrin/CaBP/Calneuron (nCaBPs) proteins are members of this latter group. They resemble the structure of their common ancestor Calmodulin (CaM) with four EF-hand Ca2+-binding motifs, of which not all are functional. However, despite their structural homology with CaM, NCS as well as nCaBPs are quite diverse in amino acid sequence. It is therefore surprising that relatively few binding partners have been identified that are not CaM targets and this raises the question of the specificity and function of these interactions. In terms of function, binding of NCS and nCaBP has frequently different consequences than binding of CaM, which substantially increases the versatility of the Ca2+ tool kit. The general idea of this special issue is to provide an overview on the function of neuronal EF-hand calcium-binding proteins in health and disease. But we will not just provide a mere collection of articles to stress the function of each protein. The issue will mainly deal with emerging concepts on Ca2+-signaling/buffering mediated by EF-hand Ca2+-binding proteins. This includes questions like features that define the functional role of a EF-hand calcium sensor in neurons, the conditions that make physiological relevance of a given interaction of a CaBP with its target plausible, the emerging synaptic role of these proteins, and mounting evidence for their role in the regulation of protein trafficking. Structural aspects and biophysical studies will be covered. Another aspect will be the role of CaBPs in brain disease states. This aspect includes studies showing that CaBPs are targets of drugs in clinical use, studies showing that expression levels of calcium-binding proteins are frequently altered in brain disease states as well as reports on mutations in EF-hand calcium sensors linked to human disease.

To present a coherent and meaningful survey of scientific research endeavour in an area that has expanded as fast as physiology and biochemistry of reproduction in the male is no mean task these days. No less prodigious than the growth of knowledge of male reproductive function has been the rate at which the outpouring of publications on this subject has continued since the appearance of 'The Biochemistry of Semen and of the Male Reproductive Tract' in 1964. Since cyclopaedic treatment of this vast literature did not appeal to us, we have made no attempt either to rehash the material contained in that book or to enlarge the bibliography beyond the nearly 3500 references included in the present treatise. At the same time, whilst writing, we felt strongly that to advance, it is necessary to understand the past, and for this reason we have not hesitated to refer (especially in the introductory chapter) to a number of those fundamental early discoveries in which today's knowledge is deeply and firmly rooted.
