Descrizione dell’editore
Cancer research has reached a major turning point. The quality and quantity of information gathered about this disease in the past twenty years has revolutionized our understanding of its origins and behavior. No one is better qualified to comment on these dramatic leaps forward than molecular biologist Robert A. Weinberg, director of one of the leading cancer research centers in the world. In One Renegade Cell , Weinberg presents an accessible and state-of-the-art account of how the disease begins and how, one day, it will be cured. Weinberg tells how the roots of cancer were uncovered in 1909 and when the first cancer-causing virus was discovered. He then moves forward to the discovery of the role of chemical carcinogens and radiation in triggering cancer, and relates the remarkable story of the discoveries of oncogenes and tumor suppressor genes, the master controllers of normal and malignant cell proliferation. This book, which presumes little prior knowledge of biology, describes the revolution in biomedical research that has finally uncovered the forces driving malignant growth. Drawing on insights that simply were not available until recently, the discoveries presented in One Renegade Cell have already begun to profoundly alter the way that we diagnose and treat human cancers.
PUBLISHERS WEEKLY
The last 20 years have brought a revolution in cancer research that will profoundly change diagnosis and treatment of the disease, writes Weinberg in this comprehensive but rigorous introduction to the subject. Weinberg, founder of the Whitehead Institute for Cancer Research and a biology professor at MIT, traces the development of previous theories of cancer, and explains that scientists are now certain that cancer is caused when genes are damaged through a succession of mutations. These can result from damage to a cell's DNA inflicted by mutagens (which can be of foreign origin, such as tobacco smoke, or of internal origin); from normal mistakes made when DNA is copied during cell growth; or from defects in the body's DNA repair machinery. Weinberg discusses the roles of chemical carcinogens, retroviruses and heredity in developing cancer, and explains the body's intricate defenses against tumor growth. Though he argues that cancer will never be fully eradicated because so many mutations occur during long lifetimes ("Given enough time, cancer will strike every human body"), Weinberg is optimistic that increasingly sophisticated understanding of cellular functions will yield more effective treatments for those cancers that cannot be prevented. Though some readers might find the technical sections of the book difficult, it readily conveys the challenge and excitement of scientific discovery. Two illustrations.
