Cancer Cell Chemoresistance And Chemosensitization

Despite the significant advances in cancer therapy made through constant evaluation and analysis of treatment aftereffects, the disease still remains one of the foremost causes of mortality worldwide killing more than 12 million people annually. The prime reason behind the failure of conventional chemotherapeutics which are used as the chief regimen in the comprehensive treatment of cancers is the development of chemoresistance. It can be either intrinsic or acquired and is primarily mediated via different key regulators like MDR, MAPK, NF-κB, PI3K/Akt, Wnt signaling pathways etc. Thus, agents which can target these regulatory elements or pathways and in turn sensitize cancer cells to chemotherapy holds immense prospect. However, there is barely such comprehensive work available in scientific literature that explains how chemosensitization of cancer cells functions using different drug combinations and exhibit synergism. This book provides a detailed description of chemoresistance and chemosensitization, targets for chemosensitization and various approaches adapted in the process of chemosensitization. Furthermore, the book explicates the role of various chemosensitizers, both natural and synthetic in sensitizing cancer cells and also details the current research findings on chemosensitization of different cancer types in both pre-clinical and clinical settings.

Nitric Oxide as a Chemosensitizing Agent, Volume One is the first book to describe several reviews by authoritative scientists and clinicians on novel findings in the reversal of drug resistant cancers by the combination treatment of Nitric Oxide and sub toxic concentrations of chemotherapeutic drugs that have been reported in both in vitro, in vivo and preclinical models. The book describes the various underlying chemical, molecular and genetic mechanisms by which NO and NO reactive species mediate the anti-cancer activity, thus reducing the threshold of drug resistance and enabling chemo therapeutic drugs to induce their cytotoxic activity and reversal of resistance. This book exposes scientists and clinicians to this highly beneficial topic for research investigations and pharmaceutical companies to new avenues for R&D. It is a valuable resource for cancer researchers, oncologists and members of several areas of the biomedical field who are interested in understanding how to use Nitric Oxide as a sensitizing agent for chemotherapy. Brings updated information as reviewed by experts in the field Presents expert analysis and summary of reported and novel findings and potential translational application in cancer patients Describes molecular mechanisms with new and helpful approaches that can be used in reader investigations

This book reviews novel approaches developed to reverse tumor cell resistance to chemo/immuno/radio-therapy and the use of various sensitizing agents in combination with various cytotoxics. It also introduces several current approaches developed by established investigators that are aimed at overcoming resistance. This is the first volume to compile studies on tumor cell sensitization. It will prove useful for students, scientists, clinicians and pharmaceutical companies.

In Breast Cancer Chemosensitivity, a group of world leading experts review critical aspects of resistance to systemic therapy in breast cancer patients. Beginning with a clinical overview of the problem, the book then focuses on the latest findings of molecular mechanisms of drug resistance. Coverage provides an example of using novel approaches for chemosensitization of breast cancer cells that gives readers an idea about the future direction in breast cancer treatment. It allows those who are interested in breast cancer therapy to get a jump-start on critical issues in breast cancer therapeutic resistance.

One of the main causes of failure in the treatment of cancer is the development of drug resistance by the cancer cells. The design of cancer chemotherapy has become increasingly sophisticated, yet there is no cancer treatment that is 100% effective against disseminated cancer. Resistance to treatment with anticancer drugs results from a variety of factors including individual variations in patients and somatic cell genetic differences in tumours, even those from the same tissue of origin. Frequently resistance is intrinsic to the cancer, but as therapy becomes more and more effective, acquired resistance has also become common. The most common reason for acquisition of resistance to a broad range of anticancer drugs is expression of one or more energy-dependent transporters that detect and eject anticancer drugs from cells, but other mechanisms of resistance including insensitivity to drug-induced apoptosis and induction of drug-detoxifying mechanisms probably play an important role in acquired anticancer drug resistance. Studies on mechanisms of cancer drug resistance have yielded important information about how to circumvent this resistance to improve cancer chemotherapy and have implications for pharmacokinetics of many commonly used drugs. This book presents new and important research in this field.

Strategies for overcoming chemotherapy resistance in cervical cancer highlights different strategies to reverse chemotherapy resistance in cervical cancer. The book has a strong focus on strategies to reverse chemotherapy resistance as well as strategies for early detection of the resistance, enhancing precision oncology in terms of patient care and maximizing patient management. The book also looks at virally induced resistance to chemotherapy and recommends combination therapies that can maximize the reversal of this resistance. In 10 chapters Strategies for overcoming chemotherapy resistance in cervical cancer not only gives an overview of cervical cancer and chemotherapy as treatment, but it also investigates resistance to chemotherapy and the treatment for resistance. It defines the treatment mechanisms, options, and limitations to beat chemotherapy resistance and the reversal of the resistance mechanisms. It gives insights into the future directions of cervical cancer treatment using epigenetic silencing, chemotherapy splicing, the involvement of MicroRNAs to chemotherapy resistance, and the application of Artificial Intelligence. This book is a valuable resource for health professionals, scientists and researchers, oncologists, virologists, health practitioners, medical and graduate students, and all those who wish to broaden their knowledge in the allied field. Discusses strategies to reverse and detect resistance to chemotherapy at an early stage Investigates the applications of Artificial Intelligence in the study of cervical chemotherapy resistance Presents research and applications developed to overcome cancer resistance
