In recent years, a number of groundbreaking structural and mechanistic studies deepened our understanding of helicase mechanisms and established new approaches for their analyses. Many fundamental mechanistic questions ranging from the mechanism of force generation, mechanochemical coupling to distinct mechanisms by which the same enzyme translocates on DNA removing obstacles, unwinds DNA and/or remodels nucleoprotein complexes, however, remain to be answered. It is even less understood how the helicase motors are incorporated into a wide range of genome maintenance and repair machines. The field has reached a stage when the studies of molecular mechanisms and basic biology of helicases can and shall be integrated with the studies of development, cancer and longevity. The objective of this book is to provide the first systematic overview of structure, function and regulation of DNA helicases and related molecular motors. By integrating the knowledge obtained through the diverse technical approaches ranging from single-molecule biophysics to cellular and molecular biological studies the editors aim to provide a unified view on how helicases function in the cell, are regulated in response to different cellular stresses and are integrated into large macromolecular assemblies to form a complex and adaptive living system.

This book provides a comprehensive overview of biomotors (molecular motors) within the body with a specific concentration on revolving molecular motors. The bioengineering of these new revolving molecular motors will go a long way in creating machines that will be able to carry RNA and DNA drugs directly to diseased cells to destroy them. The book goes into specific details regarding the bioengineering, fabrication, synthesis, and future utilization of these devices for nanomedicine.

The book represents a comprehensive review and synthesis of the biomedical literature that spans over a half-century on a single protein called glyceraldehyde 3-phosphate dehydrogenase (or, GAPDH). Due to the protein’s involvement in a vast array of cellular activities, GAPDH is of interest to the cell biologist, immunologist, virologist, biochemist etc. The protein has a significant role in fertility, cancer and neurodegeneration, suggesting that this book can be a vital resource for drug development. GAPDH function may provide insight into anesthesia. Furthermore, GAPDH is highly conserved meaning that the protein found in microorganisms, such as pathogens, remained relatively unchanged in evolution. Pathogens use GAPDH as a virulence factor, offering a unique challenge in developing anti-microbial agents that target this protein. To the evolutionary biologist, a book on the multi-functionality of GAPDH provides a focal point for a cogent discussion on the very origin of life.

In the first volume, Fundamental Concepts in Biophysics, the authors lay down a foundation for biophysics study. Rajiv Singh opens the book by pointing to the central importance of “Mathematical Methods in Biophysics”. William Fink follows with a discussion on “Quantum Mechanics Basic to Biophysical Methods”. Together, these two chapters establish some of the principles of mathematical physics underlying many biophysics techniques. Because computer modeling forms an intricate part of biophysics research, Subhadip Raychaudhuri and colleagues introduce the use of computer modeling in “Computational Modeling of Receptor–Ligand Binding and Cellular Signaling Processes”. Yin Yeh and coworkers bring to the reader’s attention the physical basis underlying the common use of fluorescence spectroscopy in biomedical research in their chapter “Fluorescence Spectroscopy”. Electrophysiologists have also applied biophysics techniques in the study of membrane proteins, and Tsung-Yu Chen et al. explore stochastic processes of ion transport in their “Electrophysiological Measurements of Membrane Proteins”. Michael Saxton takes up a key biophysics question about particle distribution and behavior in systems with spatial or temporal inhomogeneity in his chapter “Single–Particle Tracking”. Finally, in “NMR Measurement of Biomolecule Diffusion”, Thomas Jue explains how magnetic resonance techniques can map biomolecule diffusion in the cell to a theory of respiratory control. This book thus launches the Handbook of Modern Biophysics series and sets up for the reader some of the fundamental concepts underpinning the biophysics issues to be presented in future volumes.

Anomalous epigenetic patterns touch many areas of study including biomedical, scientific, and industrial. With perspectives from international experts, this resource offers an all-inclusive overview of epigenetics, which bridge DNA information and function by regulating gene expression without modifying the DNA sequence itself. Epigenetics, in its most basic form, means heredity is not the sole determining factor in disease development. Rather, environmental and dietary factors can trigger a gene to behave in an unintended way, while the gene itself remains unchanged. Epigenetics in Biology and Medicinediscusses cell biology and epigenetics’ role in human, animal, and plant diseases, including distortions in DNA methylation. The text also covers histone modifications, and epigenomics, as well as dietary and environmental impacts on epigenetic changes. Addresses These Important Questions: How promising are HDACi drugs as anti-tumor agents? Will restoring normal levels of miRNAs change the course of devastating diseases? Is it possible to alter epigenetic mechanisms once they are triggered? Is it possible to correct the abnormalities in methylation patterns that impact auto-immunities? Represents a Landmark Publication in this Cutting-Edge Field Dr. Manel Esteller, the editor of the volume, is a leading expert in molecular genetics of endometrial carcinoma. Under his editorial guidance, this publication goes beyond heredity to explain the crucial role of epigenetics in plants and physical and psychological diseases. This text is applicable to a wide range of researchers, including those invested in the applications of cell biology, those involved in disease research and deciding genetic patterns, and those coalitions concerned with the impact of epigenetics and possible cures. As a result, it has the potential to launch the development of a new class of pharmaceuticals that could have the potential to drastically change the medical landscape in the near future.

Systems Biology represents a new paradigm aiming at a whole-organism-level understanding of biological phenomena, emphasizing interconnections and functional interrelationships rather than component parts. The study of network properties, and how they control and regulate behavior from the cellular to organism level, constitutes a main focus of Systems Biology. This book addresses from a novel perspective a major unsolved biological problem: understanding how a cell works and what goes wrong in pathology. The task undertaken by the authors is in equal parts conceptual and methodological, integrative and analytical, experimental and theoretical, qualitative and quantitative, didactic and comprehensive. Essentially, they unravel the spatio-temporal unfolding of interacting mass-energy and information networks at the cellular and organ levels, as well as its modulation through activation or repression by signaling networks to produce a certain phenotype or (patho)physiological response. Starting with the historical roots, in thirteen chapters this work explores the Systems Biology of signaling networks, cellular structures and fluxes, organ and microorganism functions. In doing so, it establishes the basis of a 21st century approach to biological complexity.
