The Biology of Tumors


Book Description

The Ninth Annual Pezcoller Symposium entitled "The Biology of Tumors" was held in Rovereto, Italy, June 4-7, 1997. It focused on the genetic mechanisms underlying het erogeneity of tumor cell populations and tumor cell differentiation, on interactions be tween tumor cells and cells of host defenses, and the mechanisms of angiogenesis. With presentations at the cutting edge of progress and stimulating discussions, this symposium addressed issues related to phenomena concerned with cell regulation and cell interactions as determined by activated genes through the appropriate and timely media tion of gene products. Important methodologies that would allow scientists to measure dif ferentially genes and gene products and thus validate many of the mechanisms of control currently proposed were considered, as were the molecular basis of tumor recognition by the immune system, interactions between cells and molecular mechanisms of cell regula tion as they are affected by or implemented through these interactions. The molecular and cellular mechanisms of tumor vascularization were also discussed. It was recognized that angiogenesis provides a potential site of therapeutic intervention and this makes it even more important to understand the mechanisms underlying it. We wish to thank the participants in the symposium for their substantial contribu tions and their participation in the spirited discussions that followed. We would also like to thank Drs.




The Cell Biology of Stem Cells


Book Description

Stem cells have been gaining a lot of attention in recent years. Their unique potential to self-renew and differentiate has turned them into an attractive model for the study of basic biological questions such as cell division, replication, transcription, cell fate decisions, and more. With embryonic stem (ES) cells that can generate each cell type in the mammalian body and adult stem cells that are able to give rise to the cells within a given lineage, basic questions at different developmental stages can be addressed. Importantly, both adult and embryonic stem cells provide an excellent tool for cell therapy, making stem cell research ever more pertinent to regenerative medicine. As the title The Cell Biology of Stem Cells suggests, our book deals with multiple aspects of stem cell biology, ranging from their basic molecular characteristics to the in vivo stem cell trafficking of adult stem cells and the adult stem-cell niche, and ends with a visit to regeneration and cell fate reprogramming. In the first chapter, “Early embryonic cell fate decisions in the mouse”, Amy Ralson and Yojiro Yamanaka describe the mechanisms that support early developmental decisions in the mouse pre-implantation embryo and the current understanding of the source of the most immature stem cell types, which includes ES cells, trophoblast stem (TS) cells and extraembryonic endoderm stem (XEN) cells.




Biochemistry and Molecular Biology of Parasites


Book Description

The study of parasitic organisms at the molecular level has yielded fascinating new insights of great medical, social, and economical importance, and has pointed the way for the treatment and prevention of the diseases they cause. Biochemistry and Molecular Biology of Parasites presents an up-to-date account of this modern scientific discipline in a manner that allows and encourages the reader to place the biochemistry and molecular biology of these organisms in their biological context. The chapters are cross-referenced and grouped in an arrangement that provides a fully integrated whole, and permits the reader to create a composite of the biochemical function of these organisms.Individual chapter includes those devoted to metabolism, in both aerobic and anaerobic protozoa; antioxidant mechanisms; parasite surfaces; organelles; invasion mechanisms; and chemotherapy. The helminths are discussed not only from the point of view of their cellular biochemistry and metabolism, but also with respect to both their integrated functions such as neurochemistry, structure and functions of surfaces, and reproduction. Written by expert investigators, this book will be of interest to all experienced researchers, graduate students, and to the newcomer eager to become familiar with the biochemistry and molecular biology of parasites.




Midkine: From Embryogenesis to Pathogenesis and Therapy


Book Description

Carl Edward Sagan’s (1934-1996) one of the famous quotation was “Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.“ From past to date, well-known molecules, enzymes, proteins, lipids and carbohydrates are studied in the pathogenesis of several diseases both as a diagnostic/prognostic biomarker and therapeutic agent. The underlying mechanism of unexplained diseases and failure of therapies are frequently studied with well-known biomarkers, but remain unclear in many cases. As Dr. Sagan said other keys are still waiting to be known in some forgotten corner of a body universe, we find strength to propose that one of them can be the growth factor with cytokine activity named “Midkine” This book summarizes the extensive up-to-date literature overeview with the lastest work of experts about midkine in a detailed format that conveys its role as both a pathologic factor and therapeutic agent.




G-Quadruplex Nucleic Acids


Book Description

This volume covers the structures, properties, and functions of G-quadruplexes in a wide range of biological disciplines, including therapeutic intervention and biomaterial application. The chapters in this book explore a wide range of vital and new experimental techniques used in the study of G-quadruplexes. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Practical and cutting-edge, G-Quadruplex DNA: Methods and Protocols is a valuable resource for both novice and experienced researchers who work in biophysics, structural biology, computational biology, biochemistry, and molecular and cell biology, and who want to learn more about the potential roles and effects of G-quadruplex in these fields.




Oxidative Stress and Signal Transduction


Book Description

In the past few years there has been the increased recognition that the effects of oxidative stress are not limited to the damage of cellular constituents. There is now evidence that reactive oxygen species (ROS) can alter cell function by acting upon the intermediates, or second messengers, in signal transductions. Such effects on signaling mechanisms probably account for the role of oxidative stress in inflammation, aging, and cancer. This volume brings together internationally recognized researchers in both the major areas covered by the book, oxidative stress and signal transduction. The work is organized in three sections. The first deals with the immediate cellular responses to oxidative stress and the production of second messengers. The second details the connection between second messengers and the gene. The third part looks more closely at the level of the gene.










Mitochondria and Their Role in Cardiovascular Disease


Book Description

Over the past two decades, due to dramatic advances in molecular and cell biology, biochemistry, and genetics, our view on mitochondria as a relatively static cellular powerhouse has changed radically. We now know that these organelles play a critical role in the normal and in the damaged heart. Written by Dr. José Marín-García, Director of the Molecular Cardiology and Neuromuscular Institute, Mitochondria and Their Role in Cardiovascular Disease brings readers up- to-date on the many significant advances in the field of mitochondrial cardiovascular medicine. The book begins with a general introduction to mitochondria, followed by laboratory methods to study the structure and function of the organelle, regulation of replication and biogenesis, and the mechanisms and functional consequences of mitophagia and mitochondrial dynamics. Subsequent chapters deal with mitochondrial oxidative stress and the role that the organelle plays in cell signaling and cell death. Discussions will be undertaken on the biochemistry of mitochondrial cell signaling, including the nature of the proteins engaged in these processes, many of them only recently discovered. Later chapters examine the role of mitochondria and mitochondrial abnormalities in cardiovascular diseases, including their diagnosis, therapeutic options currently available, animal models of mitochondrial disease, and new frontiers in mitochondria cardiovascular medicine, including areas of research that are relatively new or developing, such as proteomics, next generation sequencing, and systems biology.
