Multi-Drug Resistance in Cancer


Book Description

Chemotherapy is one of the major treatment options for cancer patients; however, the efficacy of chemotherapeutic management of cancer is severely limited by multidrug resistance, in that cancer cells become simultaneously resistant to many structurally and mechanistically unrelated drugs. In the past three decades, a number of mechanisms by which cancer cells acquire multidrug resistance have been discovered. In addition, the development of agents or strategies to overcome resistance has been the subject of intense study. This book contains comprehensive and up-to-date reviews of multidrug resistance mechanisms, from over-expression of ATP-binding cassette drug transporters such as P-glycoprotein, multidrug resistance-associated proteins, and breast cancer resistance p- tein to the drug ratio-dependent antagonism and the paradigm of cancer stem cells. The book also includes strategies to overcome multidrug resistance, from the development of compounds that inhibit drug transporter function to the modulation of transporter expression. In addition, this book contains techniques for the detection and imaging of drug transporters, methods for the investigation of drug resistance in animal models, and strategies to evaluate the efficacy of resistance reversal agents. The book intends to provide a state-of-the-art collection of reviews and methods for both basic and clinician investigators who are interested in cancer multidrug resistance mechanisms and reversal strategies.

Alternative Mechanisms of Multidrug Resistance in Cancer


Book Description

Nullius in verba. . . Truth will be tested not by words. Horace (Epistles) Few read introductions except for book reviewers, who want to take a shortcut and avoid reading the book itself. However, tradition requires that the preface make public why the book was written at all (this is not supposed to include powerful reasons such as augmenting the ego of the editor and authors). Frequently, the inflationary tendency to publish in verbose length is in conflict with market forces and interest. No doubt, multidrug resistance is a "fashionable" topic, but there are many fashions displayed on the cat-walk of scientific literature. One can rationalize that the forces driving our concern with multi drug resistance reflect the frustration of pharmaceutical companies and oncologists alike: as soon as a new anticancer drug enters clinical trials, cancer cells start eluding extinction with their elaborate and successful mechanisms. Many grants have been awarded and spent, only to confirm the futility of our efforts to defeat this cellular Darwinism. Our medical and scientific training makes it hard, if not impossible, to accept that the survival of a malignant cell, alone or as part of a tissue, is part of the continuance of life. Since exposure to noxious and lethal substances is unavoidable, cells have been forced to develop a multitude of mechanisms to prevent entry or accelerate exit of such materials from intracellular space.

Drug Resistance in Leukemia &


Book Description

The last ten years have seen the publication of a vast amount of data regarding cellular resistance to drugs in cancer cells. Recent studies have demonstrated that drug resistance assays appear to be predictive of clinical response and suggest that clinicians should now be considering the potential applications of these assays in the treatment of patients with hematological neoplasms. This collection of papers from the International Symposium on the Clinical Value of Drug Resistance Assays in Leukemia and Lymphoma, Amsterdam, 1992, provides a state-of-the-art discussion on drug resistance assays and their role in the design and individualization of treatment protocols.

Necrotic Cell Death


Book Description

Starting with discussion of basic concepts and the molecular mechanisms of necrosis, this book looks first at several forms of necrotic cell death that have been identified, including necroptosis, autophagic cell death, and PARP-mediated cell death. As necrotic cell death is increasingly known to play a critical role in many physiological processes, the next chapters discuss its effect on metabolism, inflammation, immunity, and development. Necrotic cell death is closely implicated in human diseases like cancer, so the next chapters examine its relevance to human diseases, and final chapters cover methodologies for measuring necrosis. This book presents comprehensive coverage of necrosis from recognized experts from leading academic and medical institutions around the world. ​In contrast to apoptosis, well-defined as a form of programmed cell death, necrosis used to be considered as accidental (i.e., non-programmed) cell death, usually in response to a severe injury. Accumulating evidence now suggests, however, that necrosis is also programmed and controlled by distinctive "death machinery" in response to various stimuli like oxidative stress or DNA damage.
