Book Description
The epidermal gro wth factor (EGF ) receptor and its downstream signal transduction networks have been implicated in the ontology and maintenance of tumor tissues, which has motivated the discovery and development of molecularly targeted anti-EGF receptor therapies. Over decades of study, the EGF receptor structure, its ligand binding domains, the physical biochemistry underlying its intrinsic tyrosine kinase catalytic function and the modular interactions with SH2, PTB, and SH3 domain containing signaling adaptor p- teins required for signal transduction, have been extensively dissected. Not only is the EGF receptor the nexus of many streams of information, but it also forms one part of a calcul- ing device by forming dimers and oligomers with the other three receptors in its family in response to at least eleven ligands (some of which are expressed in multiple forms with overlapping or quite distinct functions). This phenomenon, while recruiting to the inner surface of the cell membrane and activating multiple second messenger proteins, also allows the possibility of cross talk between these systems, permitting a further layer of information to be exchanged. Less well described are the cross re gulation of the EGF receptor and other anti-apoptotic, mitogenic and metabolic signaling systems. The study of these systems has yielded new surprises. One hurdle in these efforts has been that signal transduction pathways have frequently been defined in the generic absence of their tissue-specific or cell-interaction specific context.

Book Description
Cancer, which has become the second-most prevalent health issue globally, is essentially a malfunction of cell signaling. Understanding how the intricate signaling networks of cells and tissues allow cancer to thrive - and how they can be turned into potent weapons against it - is the key to managing cancer in the clinic and improving the outcome of cancer therapies. In their ground-breaking textbook, the authors provide a compelling story of how cancer works on the molecular level, and how targeted therapies using kinase inhibitors and other modulators of signaling pathways can contain and eventually cure it. The first part of the book gives an introduction into the cell and molecular biology of cancer, focusing on the key mechanisms of cancer formation. The second part of the book introduces the main signaling transduction mechanisms responsible for carcinogenesis and compares their function in healthy versus cancer cells. In contrast to the complexity of its topic, the text is easy to read. 32 specially prepared teaching videos on key concepts and pathways in cancer signaling are available online for users of the print edition and have been integrated into the text in the enhanced e-book edition.

Book Description
This thesis explores the problem of cancer metastasis by analyzing the various downstream components of the epidermal growth factor receptor (EGFR) pathway. This work develops a mathematical model that consists of partial differential equations and signaling networks. Analysis techniques for these nonlinear reaction-diffusion equations included a study of the biological background and motivation, along with computational simulation of the various sets of models developed. The modeling effort combined biochemical reaction-diffusion equations for various species with mathematical descriptions of the mechanical machinery of the cell to characterize the foundations of cell movement in response to stimuli. By quantifying and qualifying the signaling networks and molecular pathways involved in cellular signaling and linking intracellular signaling to the mechanical machinery of the cell, it is possible to quickly check in silico the effects of changing various feedback parameters and signaling molecule concentrations. By creating a model of this process, it is possible to perform rapid tests of different pharmaceuticals on the biochemical and biomechanical pathways, in order to assess how they would affect cell motility and cancer metastasis on a large scale.

Book Description
The epidermal growth factor receptor (EGFR) is one of the first and most extensively studied receptor tyrosine protein kinases and a validated drug target. Through protein phosphorylation EGFR orchestrates several signaling pathways that regulate cell growth and proliferation, and aberrant EGFR signaling has been reported in numerous cancer types. Several FDA-approved drugs target the ATP site of EGFR, and new therapeutics are in development that target the signaling partners of oncogenic EGFR. However, resistance is a challenge to overcome, and other EGFR-associated signaling proteins have been shown to confer resistance. Chemical probes may aid the elucidation of EGFR signaling networks for finding improved combination therapies. Here we report the sunthesis of first-generation biotinylated chemical probes 1a-1c targeting EGFR. These probes are based on the 4-aniloquinazoline core structure of gefitinib and erlotinib, two FDA-approved EGFR-targeting drugs. The probes 1a-1c exhibit excellent binding affinities for EGFR (Kd=23-41 nM). These probes are expected to serve as the basis for future development of next-generation multifunctional probes for understanding exogenous EGFR signaling networks.

Book Description
The second edition of this encyclopedia presents over 400 biologically important signaling molecules and the content is built on the core concepts of their functions along with early findings written by some of the world’s foremost experts. The molecules are described by recognized leaders in each molecule. The interactions of these single molecules in signal transduction networks will also be explored. This encyclopedia marks a new era in overview of current cellular signaling molecules for the specialist and the interested non-specialist alike. Currently, there are more than 30,000 genes in human genome. However, not all the proteins encoded by these genes work equally in order to maintain homeostasis. Understanding the important signaling molecules as completely as possible will significantly improve our research-based teaching and scientific capabilities.

Book Description
One of the most exciting areas of cancer research now is the development of agents which can target signal transduction pathways that are activated inappropriately in malignant cells. The understanding of the molecular abnormalities which distinguish malignant cells from their normal counterparts has grown tremendously. This volume summarizes the current research on the role that signal transduction pathways play in the pathogenesis of cancer and how this knowledge may be used to develop the next generation of more effective and less toxic anticancer agents. Series Editor comments: "The biologic behavior of both normal and cancer cells is determined by critical signal transduction pathways. This text provides a comprehensive review of the field. Leading investigators discuss key molecules that may prove to be important diagnostic and/or therapeutic targets."

Book Description
Receptor tyrosine kinases are cell-surface receptors that respond to numerous hormones and growth factors, including insulin, insulin-like growth factors, epidermal growth factor, and nerve growth factor. They activate highly conserved intracellular signaling pathways that regulate cell proliferation, differentiation, and metabolism, playing essential roles in developing and adult animals. This book examines the nature of these receptors and their ligands, the molecular mechanisms that they regulate within cells, and the roles of the receptors in normal physiology and control of embryogenesis. It also discusses how dysfunction of these mechanisms can contribute to cancer and other diseases.
