Book Description
Decades of research on the tumor suppressor p53 have revealed that it plays a significant role as a "guardian of the genome," protecting cells against genotoxic stress. In recent years, p53 research has begun to move into the clinic in attempts to understand how p53 is frequently inactivated in-and sometimes even promotes-human cancer. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine covers the rapid progress that has recently been made in basic and clinical research on p53. The contributors review new observations about its basic biology, providing updates on the functions of its isoforms and domains, the myriad stresses and signals that trigger its activation or repression, and its downstream effects on genome stability and the cell cycle that enforce tumor suppression in different cell and tissue types. They also discuss how p53 dysfunction contributes to cancer, exploring the various inherited and somatic mutations in the human TP53 gene, the impact of mutant p53 proteins on tumorigenesis, and the prognostic value and clinical outcomes of these mutations. Drugs that are being developed to respond to tumors harboring aberrant p53 are also described. This book is therefore essential reading for all cancer biologists, cell and molecular biologists, and pharmacologists concerned with the treatment of this disease.

Book Description
All of us have lurking in our DNA a most remarkable gene, which has a crucial job - it protects us from cancer. Known simply as p53, this gene constantly scans our cells to ensure that they grow and divide without mishap, as part of the routine maintenance of our bodies. If a cell makes a mistake in copying its DNA during the process of division, p53 stops it in its tracks, summoning a repair team before allowing the cell to carry on dividing. If the mistake is irreparable and the rogue cell threatens to grow out of control, p53 commands the cell to commit suicide. Cancer cannot develop unless p53 itself is damaged or prevented from functioning normally. Perhaps unsurprisingly, p53 is the most studied single gene in history. This book tells the story of medical science's mission to unravel the mysteries of this crucial gene, and to get to the heart of what happens in our cells when they turn cancerous. Through the personal accounts of key researchers, p53: The Gene that Cracked the Cancer Code reveals the fascination of the quest for scientific understanding, as well as the huge excitement of the chase for new cures - the hype, the enthusiasm, the lost opportunities, the blind alleys, and the thrilling breakthroughs. And as the long-anticipated revolution in cancer treatment tailored to each individual patient's symptoms begins to take off at last, p53 remains at the cutting edge. This timely tale of scientific discovery highlights the tremendous recent advances made in our understanding of cancer, a disease that affects more than one in three of us at some point in our lives.

The Cancer Code

Pages : 368

Book Description
Author of the international bestsellers The Diabetes Code and The Obesity Code Dr. Jason Fung returns with an eye-opening biography of cancer in which he offers a radical new paradigm for understanding cancer—and issues a call to action for reducing risk moving forward. Our understanding of cancer is slowly undergoing a revolution, allowing for the development of more effective treatments. For the first time ever, the death rate from cancer is showing a steady decline . . . but the “War on Cancer” has hardly been won. In The Cancer Code, Dr. Jason Fung offers a revolutionary new understanding of this invasive, often fatal disease—what it is, how it manifests, and why it is so challenging to treat. In this rousing narrative, Dr. Fung identifies the medical community’s many missteps in cancer research—in particular, its focus on genetics, or what he terms the “seed” of cancer, at the expense of examining the “soil,” or the conditions under which cancer flourishes. Dr. Fung—whose groundbreaking work in the treatment of obesity and diabetes has won him international acclaim—suggests that the primary disease pathway of cancer is caused by the dysregulation of insulin. In fact, obesity and type 2 diabetes significantly increase an individual’s risk of cancer. In this accessible read, Dr. Fung provides a new paradigm for dealing with cancer, with recommendations for what we can do to create a hostile soil for this dangerous seed. One such strategy is intermittent fasting, which reduces blood glucose, lowering insulin levels. Another, eliminating intake of insulin-stimulating foods, such as sugar and refined carbohydrates. For hundreds of years, cancer has been portrayed as a foreign invader we’ve been powerless to stop. By reshaping our view of cancer as an internal uprising of our own healthy cells, we can begin to take back control. The seed of cancer may exist in all of us, but the power to change the soil is in our hands.

The p53 Tumor Suppressor Pathway and Cancer

Book Description
The current year (2004) marks the Silver Anniversary of the discovery of the p53 tumor suppressor. The emerging ?eld ?rst considered p53 as a viral antigen and then as an oncogene that cooperates with activated ras in transforming primary cells in culture. Fueling the concept of p53 acting as a transforming factor, p53 expression was markedly elevated in various transformed and tumorigenic cell lines when compared to normal cells. In a simple twist of fate, most of the studies conducted in those early years inadvertently relied on a point mutant of p53 that had been cloned from a normal mouse genomic library. A bona ?de wild-type p53 cDNA was subsequently isolated, ironically, from a mouse teratocarcinoma cell line. A decade after its discovery, p53 was shown to be a tumor suppressor that protects against cancer. It is now recognized that approximately half of all human tumors arise due to mutations within the p53 gene. As remarkable as this number may seem, it signi?cantly underrepresents how often the p53 pathway is targeted during tumorigenesis. It is my personal view, as well as many in the p53 ?eld, that the p53-signaling pathway is corrupted in nearly 100% of tumors. If you are interested in understanding cancer and how it develops, you must begin by studying p53 and its pathway. After demonstrating that p53 functions as a tumor suppressor the ?eld exploded and p53 became a major focus of scientists around the world.

Pages : 241

Book Description
Two years after she underwent a mastectomy and chemotherapy, Barbara Bradfield's aggressive breast cancer had recurred and spread to her lungs. The outlook was grim. Then she took part in Genentech's clinical trials for a new drug. Five years later she remains cancer-free. Her-2 is the biography of Herceptin, the drug that provoked dramatic responses in Barbara Bradfield and other women in the trials and that offers promise for hundreds of thousands of breast cancer patients. Unlike chemotherapy or radiation, Herceptin has no disabling side effects. It works by inactivating Her-2/neu--a protein that makes cancer cells grow especially quickly-- produced by a gene found in 25 to 30 percent of all breast tumors. Herceptin caused some patients' cancers to disappear completely; in others, it slowed the progression of the disease and gave the women months or years they wouldn't otherwise have had. Herceptin is the first treatment targeted at a gene defect that gives rise to cancer. It marks the beginning of a new era of treatment for all kinds of cancers. Robert Bazell presents a riveting account of how Herceptin was born. Her-2 is a story of dramatic discoveries and strong personalities, showing the combination of scientific investigation, money, politics, ego, corporate decisions, patient activism, and luck involved in moving this groundbreaking drug from the lab to a patient's bedside. Bazell's deft portraits introduce us to the remarkable people instrumental in Herceptin's history, including Dr. Dennis Slamon, the driven UCLA oncologist who played the primary role in developing the treatment; Lily Tartikoff, wife of television executive Brandon Tartikoff, who tapped into Hollywood money and glamour to help fund Slamon's research; and Marti Nelson, who inspired the activists who lobbied for a "compassionate use" program that would allow women outside the clinical trials to have access to the limited supplies of Herceptin prior to FDA approval of the drug. And throughout there are the stories of the heroic women with advanced breast cancer who volunteered for the trials, risking what time they had left on an unproven treatment. Meticulously researched, written with clarity and compassion, Her-2 is masterly reporting on cutting-edge science.
