Tumor Suppressor Par-4: Structural Features, Molecular Mechanisms and Function
by Vivek M. RangnekarPar-4 is a tumor suppressor protein first discovered and identified in 1993 by Dr. Vivek Rangnekar’s laboratory in prostate cancer cells undergoing apoptosis. Par-4 (later also known as PAWR) is a naturally occurring tumor suppressor. Studies have indicated that Par-4 selectively induces apoptosis in cancer cells while leaving normal, healthy, cells unaffected. Mechanisms contributing to the cancer-selective action of Par-4 have been associated with protein kinase A activation of intracellular Par-4 in cancer cells or GRP78 expression primarily on the surface of cancer cells. Par-4 is downregulated, inactivated or mutated in diverse cancers. This first of two volumes will be the first on the market on the topic of Par-4, and will provide the opportunity for researchers to discuss the future direction of studies, broaden the scope of research, and contribute a more complete understanding of the molecule’s structural features, key functional domains, regulation and relevant basic and clinical/translational facets.
Tumor Suppressor Par-4: Role in Cancer and Other Diseases
by Vivek M. RangnekarPar-4 is a naturally occurring tumor suppressor. Studies have indicated that overexpression of Par-4 selectively induces apoptosis in cancer cells while leaving normal, health, cells unaffected. Mechanisms contributing to this cancer-selective action of Par-4 have been associated with PKA activation of intracellular Par-4 in cancer cells or GRP78 expression primarily on the surface of cancer cells. On the other hand, endogenous Par-4 sensitizes cells to the action of a broad range of apoptotic inducers acting via the extrinsic and intrinsic pathways. A number of binding partners of Par-4 have been identified and shown to regulate Par-4 function in cancer and other diseases, such as Alzheimer’s and major depression. Recent studies have recognized a number of natural products, dietary supplements, synthetic molecules and FDA-approved drugs that induce the secretion of Par-4 protein to cause apoptosis in primary or metastatic tumors, one of which is in clinical trials. More than 50 different laboratories worldwide are involved in Par-4 based research of this unique protein that has progressed from the bench to clinical trials. This second, companion volume will provide a comprehensive overview of Par-4’s role in cancer and other diseases. Chapters are written by leading researchers, and will be useful for a broad audience across the scientific community, particularly students and trainees, who are the next generation of scientists and clinicians to participate in new studies and discoveries on Par-4.
Tumor Therapeutic Regimens and Comprehensive Evaluation: A comprehensive evaluation of malignant tumor treatments for clinicians
by Qiu Li Xiao-Shi ZhangThis book starts from the clinical reality, take practicality as the purpose, closely integrate clinical work, including important clinical therapeutic regimens for various cancer, and describes the new developments in treatment of common malignant tumors. At the same time, in combination with improved version of the ASCO value framework, systematic and standardized comparisons and in-depth evaluations of therapeutic regimens were made to promote the standardization of medical treatment decisions for malignant tumors. Compared with the traditional evaluation method of malignant tumor therapeutic regimens, the evaluation method of this book has outstanding advantages. First, the evaluation indicators are comprehensive and diverse. The evaluation includes multiple indicators such as clinical benefits, adverse reactions, additional benefits, and costs, and includes more effective evaluation indicators to comprehensively evaluate the treatment plan. Second, the evaluation indicators are converted into numerical values, and different indicators are effectively quantified to make the result evaluation easier and more objective. This book systematically and comprehensively reflects the highest level of diagnosis and treatment of common oncology from a new perspective. It has great clinical guidance value and will be a valuable reference book for clinicians, medical students, graduate students and related researchers.
