Ras and Cancer in the 21st Century

Author: Linda VanAelst
Publisher: Perspectives Cshl
ISBN: 9781621822219
Category : Medical
Languages : en
Pages : 300

Book Description
Ras proteins are key molecular switches in cell signaling pathways that, when activated, trigger cell growth and division. Mutations that produce abnormally active Ras proteins are common in human cancers, particularly those of the pancreas, lung, and colon. These cancers can be difficult to treat because Ras oncoproteins have long been considered 'undruggable.' Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine covers the recent progress that has been made in understanding Ras biology, how Ras activation leads to tumorigenesis, and ways in which oncogenic Ras signaling may be targeted therapeutically. The contributors review the biochemical characteristics of the different Ras isoforms (HRAS, KRAS, and NRAS), their main effectors and signaling pathways, and the mutations that lead to their constitutive activation. Recent work showing that some Ras oncoproteins may be effectively inhibited by small molecules is covered, as is work on alternative targets (e.g., enzymes that catalyze posttranslational modifications of Ras) and inhibitors (e.g., nucleic acids). The authors also discuss how organoids and mouse models are being used to study tumor progression and therapeutic efficacy. This volume is therefore essential reading for all cancer biologists, cell and molecular biologists, and pharmacologists concerned with understanding and treating Ras-driven cancers.

Waking and the Reticular Activating System in Health and Disease

Author: Edgar Garcia-Rill
Publisher: Academic Press
ISBN: 0128016329
Category : Medical
Languages : en
Pages : 330

Book Description
Waking and the Reticular Activating System in Health and Disease provides a comprehensive overview on the "activating properties of the RAS. In health, the RAS provides the basis against which we assess the external world, and in disease it distorts that world and shatters our self-image. This book describes the physiology of each process, how it is disturbed in each disorder, and what the most appropriate treatment should be. Dr. Garcia-Rill, along with contributions from leading specialists, discusses the understanding of the RAS as a system not only modulating waking, but also in charge of survival mechanisms such as fight vs flight responses and reflexes. The full spectrum of these functions helps explain the complexity of symptoms evident in such disorders as disparate as schizophrenia and Parkinson's disease. The book reviews the mechanisms that control waking and arousal, and especially how those mechanisms malfunction in certain neurological and psychiatric disorders. - First comprehensive overview on the RAS and its role in schizophrenia, major depression, autism, Parkinson's, Alzheimer's, and other neurologic and mental diseases - Offers a new way of thinking about brain function and the role of the RAS in our waking lives - Written by a leading translational neuroscience researcher with contributions by specialists in the field

The Protective Arm of the Renin Angiotensin System (RAS)

Author: Thomas Unger
Publisher: Academic Press
ISBN: 0128014857
Category : Medical
Languages : en
Pages : 312

Book Description
The Protective Arm of the Renin Angiotensin System: Functional Aspects and Therapeutic Implications is the first comprehensive publication to signal the protective role of a distinct part of the renin–angiotensin system (RAS), providing readers with early insight into a complex system which will become of major medical importance in the near future. Focusing on recent research, The Protective Arm of the Renin Angiotensin System presents a host of new experimental studies on specific components of the RAS, namely angiotensin AT2 receptors (AT2R), the angiotensin (1–7) peptide with its receptor Mas, and the enzyme ACE 2, which exert significant beneficial, health-promoting actions by counterbalancing the well-known harmful arm of the RAS with its classical angiotensin AT1 receptor. This innovative concept of the protective arm of the RAS, examined in this reference, represents an indispensable background and will be a strong support for biomedical students, researchers, cardiologists, surgeons, nephrologists, diabetologists, and endocrinologists, as well as any other physician or researcher concerned with RAS physiology, pathophysiology and clinical implications. - Provides a complete understanding of the protective side of the Renin Angiotensin System (RAS) involving angiotensin AT2 receptor, ACE2, and Ang(1-7)/Mas receptor - Combines the knowledge of editors who pioneered research on the protective renin angiotensin system including; Dr. Thomas Unger, one of the founders of AT2 receptor research; Dr. Ulrike M. Steckelings, who contributed significantly to first preclinical studies with a novel specific AT2-agonist, and Dr. Robson Santos who pioneered research on angiotensin-(1-7) and its receptor Mas. - Shows that the protective RAS axes are able to ameliorate the course of several cardiovascular, renal, metabolic and neurological diseases - Provides the basis for the understanding of a novel therapeutic approach to stimulate components of the protective arm of the RAS.

Book Description
This first of two volumes provides a general overview of the genetics, structure, mechanism and regulation of the Ras superfamily proteins and describes in detail the signaling pathways and processes regulated by specific members of this family. The focus of this first volume is on the Rho and Ras subfamily of small G proteins. Renowned scientists provide insights into the biochemistry of the classical and non-classical small G-protein family members, their spatio-temporal regulation, their effectors and their roles in health and disease. Together with Volume 2, this book provides a comprehensive and state-of-the-art work on small G-proteins (GTPases). It is intended for graduates and professors in biochemistry and cell biology already working on small G-proteins (small GTPases), but also offers an extremely valuable resource for those readers who are new to the field.

Breaking the HEC-RAS Code

Author: Christopher Goodell
Publisher: H2ls
ISBN: 9780990891802
Category : HEC-RAS (Computer program).
Languages : en
Pages : 264

Book Description
One of the most powerful, yet relatively unknown features available in HEC-RAS is the HECRASController. TheHECRASController API has a wealth of procedures which allow a programmer to manipulate HEC-RAS externally by setting input data, retrieving input or output data, and performing common functions such as opening and closing HEC-RAS, changing plans, running HEC-RAS, and plotting output. HECRASController applications are seemingly endless. Not only can the retrieval and post-processing of output be automated, but with the HECRASController, real-time modeling and probabilistic experiments like Monte Carlo are possible. If you have HEC-RAS on your computer, you already have the HECRASController! "Breaking the HEC-RAS Code" explains how the HECRASController works, provides example applications of the HECRASController, and catalogs the vast array of programming procedures (with explanations and examples on how to use them) embedded in the HECRASController. This is a "must-have" book for all HEC-RAS users. Professionals: Give yourself an edge for the next proposal and do something groundbreaking with HEC-RAS. Students: Make yourself marketable by adding the skills offered in this book.

Bioinformatics of Non Small Cell Lung Cancer and the Ras Proto-Oncogene

Author: Amita Kashyap
Publisher: Springer
ISBN: 9814585084
Category : Technology & Engineering
Languages : en
Pages : 79

Book Description
Cancer is initiated by activation of oncogenes or inactivation of tumor suppressor genes. Mutations in the K-ras proto-oncogene are responsible for 10–30% of adenocarcinomas. Clinical Findings point to a wide variety of other cancers contributing to lung cancer incidence. Such a scenario makes identification of lung cancer difficult and thus identifying its mechanisms can contribute to the society. Identifying unique conserved patterns common to contributing proto-oncogenes may further be a boon to Pharmacogenomics and pharmacoinformatics. This calls for ab initio/de novo drug discovery that in turn will require a comprehensive in silico approach of Sequence, Domain, Phylogenetic and Structural analysis of the receptors, ligand screening and optimization and detailed Docking studies. This brief involves extensive role of the RAS subfamily that includes a set of proteins, which cause an over expression of cancer-causing genes like M-ras and initiate tumour formation in lungs. SNP Studies and Structure based drug discovery will also be undertaken.
