Recently, there has been an increase of interest in the discovery and design of drugs that cleave DNA and RNA with sequence specificity. This class of compounds can be used as therapeutic agents, especially in the treatment of cancer and viral diseases. Novel mechanisms have also been discovered, allowing such agents to be used as tools in the study of the structure and function of nucleic acids. The major advances have been achieved with enediyne antibiotics and their synthetic analogues, bleomycin-metal complexes, metal-drug complexes, ribozymes and their mimics, and antisense and antigene oligonucleotides. This study discusses DNA cleavage by enediyne molecules, the mechanism of action of bleomycin, the paradigm of DNA cleavers site-specific DNA and RNA cleavage and its mechanism, RNA cleavage by RNase H, RNA hydrolysis by ribozymes and metal complexes, and redox regulation of the human immunodeficiency virus.
As our understanding of apoptotic pathway expands, we are coming to realize the great potential of utilizing this pathway to treat diseases such as cancer. The book attempts to review, summarize, and speculate on the apoptotic pathways, how are they regulated and how targeted therapies are being used to treat a wide variety of diseases. Special emphasis is placed on cancer since new treatments either being developed or currently in the clinical setting are showing great promise to increase survival rates for cancer patients. Chapters will address the biology behind regulating the apoptotic pathways and what goes wrong in disease states whereas other chapters will concentrate on new therapies targeting apoptotic pathways. The reader by the end of the book should have greater insight into the understanding and utilization of apoptotic pathways to fight diseases such as cancer.
generated a plethora of well-controlled randomized trials to This second edition of the Atlas of the Prostate summarizes the current evaluation and treatment of prostatic diseases. Diseases of investigate nearly every facet of management. The individuals who conducted many of these clinical trials, which so precisely the prostate invariably affect men as they age into their sixth decade of life and beyond, and physicians who provide care for inform us as to the efficacy of these treatments, are in many older men invariably devote a greater portion of their clinical instances authors in this Atlas. attention to the prostate. This Atlas conveys important information Prostate cancer management has likewise been an area of inno to practicing clinicians using figures, images, tables, and algo vation and change in practice patterns. The emergence of rithms in a most artful rendition. The contributors are practicing brachytherapy with seed implantation of the prostate, new strate clinicians, and they have produced a clear and concise review of gies for androgen manipulation of advanced prostatic cancer, and prostatic diseases. The format emphasizes figures and tables over further attempts to identify effective chemotherapeutic agents are some of the advances in prostate cancer management seen in the text to accurately and quickly provide the pertinent thoughts regarding prostatic disease management for the busy clinician. past one to two decades.
Advances in research and the treatment of cancer mean that more patients and their carers are asking healthcare professionals about the latest treatments and how they may be of benefit. It is essential that staff working with cancer patients understand fully how these new treatments work in order to disseminate timely and appropriate information to patients. The application of biology to the delivery of cancer care is playing an ever-increasing role in the management of these diseases. The Biology of Cancer: Second Edition provides details of the most recent developments in cancer care and is divided into three sections: Understanding Cancer – examines predisposing factors to developing cancer, diagnosis and its implications on the individual and society. The Science of Cancer – a closer look at the cell, genetics, the immune system, tumour markers and monoclonal antibodies. Research and Treatment – exploring translational oncology, applying research methodology to cancer research and research ethics relating to cancer. This fully updated edition also looks at evidence-based research that can be translated directly to patient care and gives details recent developments. Written by experienced, practicing healthcare professionals, The Biology of Cancer: Second Edition can easily be applied to patient care. It is an informative text for students, newly qualified nurses and practising oncology/palliative care nurses.
Every time a cell divides, a copy of its genomic DNA has to be faithfully copied to generate new genomic DNA for the daughter cells. The process of DNA replication needs to be precisely regulated to ensure that replication of the genome is complete and accurate, but that re-replication does not occur. Errors in DNA replication can lead to genome instability and cancer. The process of replication initiation is of paramount importance, because once the cell is committed to replicate DNA, it must finish this process. A great deal of progress has been made in understanding how DNA replication is initiated in eukaryotic cells in the past ten years, but this is the first one-source book on these findings. The Initiation of DNA Replication in Eukaryotes will focus on how DNA replication is initiated in eukaryotic cells. While the concept of replication initiation is simple, its elaborate regulation and integration with other cell processes results in a high level of complexity. This book will cover how the position of replication initiation is chosen, how replication initiation is integrated with the phases of the cell cycle, and how it is regulated in the case of damage to DNA. It is the cellular protein machinery that enables replication initiation to be activated and regulated. We now have an in-depth understanding of how cellular proteins work together to start DNA replication, and this new resource will reveal a mechanistic description of DNA replication initiation as well.
The interplay between tumors and their immunologic microenvironment is complex, difficult to decipher, but its understanding is of seminal importance for the development of novel prognostic markers and therapeutic strategies. The present review discusses tumor-immune interactions in several human cancers that illustrate various aspects of this complexity and proposes an integrated scheme of the impact of local immune reactions on clinical outcome. Current active immunotherapy trials have shown durable tumor regressions in a fraction of patients. However, clinical efficacy of current vaccines is limited, possibly because tumors skew the immune system by means of myeloid-derived suppressor cells, inflammatory type 2 T cells and regulatory T cells (Tregs), all of which prevent the generation of effector cells. To improve the clinical efficacy of cancer vaccines in patients with metastatic disease, we need to design novel and improved strategies that can boost adaptive immunity to cancer, help overcome Tregs and allow the breakdown of the immunosuppressive tumor microenvironment.
The book describes how the balance between pro- and anti-inflammatory molecules is related to health and disease. It is suggested that many diseases are initiated and their progress is influenced by inflammatory molecules and a decrease in the production and/or action of anti-inflammatory molecules and this imbalance between pro- and anti-inflammatory molecules seems to have been initiated in the perinatal period. This implies that strategies to prevent and manage various adult diseases should start in the perinatal period. An alteration in the metaolism of essential fatty acids and their anti-inflammatory molecules such as lipoxins, resolvins, protecitns, maresins and nitrolipids seems to play a major role in the pathobiology of several adult diseases. Based on these concepts, novel therapeutic approaches in the management of insulin resistance, obesity, type 2 diabetes mellitus, metabolic syndrome, cancer, lupus, rheumatoid arthritis and other auto-immune diseases are presented. Based on all these evidences, a unified concept that several adult diseases are due to an alteration in the balance between pro- and anti-inflammatory molecules is discussed and novel methods of their management are presented.
This book will provide latest insights in the functional potentials of ribonucleic acids in medine and the use of Spiegelmer and Spiegelzyme systems. It will also deal with a new type of delivery systems for cellular targeting.
