Molecular Biology of Human Cancers: An Advanced Student's Textbook
Presents many of the molecules and mechanisms generally important in human cancers. Following an overview on the cancer problem, individual chapters deal with cancer genetics and epigenetics, DNA damage and repair, oncogenes, tumor suppressors, regulatory pathways in cancer, apoptosis, cellular senescence, tumor invasion, and metastasis. A consensus is emerging that while these common mechanisms and molecules are all relevant to human cancers, in each cancer type (or even subtype) a selection of them are extremely important. For selected cancers, the route from genetic and epigenetic changes to their biological and clinical behavior can already be traced. Part II of the book presents a broad, but exemplary selection of cancers that serve as paradigms to illustrate this point. In fact, cancer research has now reached a critical stage, in which the accumulated knowledge on molecular mechanisms is gradually translated into improved prevention, diagnosis, and treatment. The state, pitfalls, and potential of these efforts are summarized in Part III. More than ever, cancer research is now an interdisciplinary effort which requires a basic knowledge of commonly used terms, facts, issues, and concepts. The aim of this book is to provide advanced students and practitioners of different disciplines with this basis, bridging the gap between standard textbooks of molecular biology, pathology, and oncology on the one hand and the specialized cancer literature on the other.
Free-Radical-Induced DNA Damage and Its Repair : A Chemical Perspective
Understanding of the molecular basis of DNA damage and its repair has increased dramatically in recent years, and substantial knowledge now exists concerning the products arising from free-radical attack on DNA. Free-radical DNA damage may lead to mutations, cancer, and cell death. Free radicals have various sources, notably ionizing radiation and oxidative stress. In radiotherapy for cancer and with some anticancer drugs, use is made of cell death by excessive DNA damage. The mechanisms leading to products of free-radical attack which have been studied in models and with small double-stranded DNA fragments are discussed in detail, and the basics of the underlying free-radical chemistry are dealt with in separate chapters.
Effect of antioxidants in plant extracts and free radicals on blood sample
Antioxidants are substances that inhibit and regulate the formation of free radicals, and prevent or slow down the damage to cells caused by free radicals. There is a balance between antioxidants and free radicals throughout the body, and free radicals become dangerous when the balance is disturbed Free radicals play a key role in many physiological decisions in cells. Since free radicals are toxic to cellular components, it is known that they cause DNA damage, contribute to DNA instability and mutation and thus favor carcinogenesis.Low levels of free radicals and steady state levels of antioxidant enzymes are responsible for the fine tuning of redox status inside cells. A change in redox state is a way to modify the physiological status of the cell.Many healthful foods contain antioxidants. If a person consumes some or all of these foods regularly, they may increase their antioxidant levels, potentially helping them prevent the damage that doctors associate with oxidative stress.
DNA damage detection : Methods and protocols
Explores techniques in DNA damage analysis, important not only for understanding cellular health after exposure to genotoxic agents but also for assessing cellular ability of genome maintenance. The book explores traditional DNA damage measurement methods, as well as modern fluorescence-based analysis and high throughput automatic analysis methods. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
Checkpoint Responses in Cancer Therapy
This book’s distinguished panel of authors takes a close look at topics ranging from the major molecular players affecting DNA synthesis and the response to DNA damage to advances made in the identification of chemical compounds capable of inhibiting individual mitotic kinases. Illuminating and authoritative, Checkpoint Responses in Cancer Therapy offers a critical summary of findings for researchers in the pharmaceutical and biotechnology industries and a valuable resource for academic scientists in cancer research and the study of cell-cycle regulation, signal transduction and apoptosis.
Charge Migration in DNA : Perspectives from Physics, Chemistry, and Biology
Charge migration through DNA has been the focus of considerable interest in recent years. A deeper understanding of the nature of charge transfer and transport along the double helix is important in fields as diverse as physics, chemistry and nanotechnology. It has also important implications in biology, in particular in DNA damage and repair. This book presents contributions from an international team of researchers active in this field.
Cell Cycle Regulation
The cell cycle is tightly regulated on many different levels to ensure properly controlled proliferation. Deregulation of cell cycle regulation is a hallmark of cancer. In this book, many aspects of cell cycle regulation are discussed, which include G1, S, M phase control, ubiquitin-mediated degradation, DNA damage response, mitotic spindle checkpoint, the centrosome cycle, Retinoblastoma protein family, the Myc oncogene, and mouse models for tumor suppressors, cyclin-dependent kinases, and meiosis. These chapters written by experts provide an updated view on how the cell cycle is regulated in vivo and about the involvement of cell cycle regulators in cancer.
Bacteriophage therapy : a potential solution for antibiotic resistance crisis
For many years, humans have been fighting with bacteria, in a matter of fact, bacteria have been winning for the last decade, becoming resistant to every weapon we have; The antibiotics. In order to win the fight humans had to think of alternative ways, like viruses. There is a special type of viruses that have been in a war with bacteria for millenniums, Bacteriophages. Bacteriophages (or phages), the most abundant viral entity of the planet. On the basis of their unique characteristics and anti-bacterial property, phages are being the freshly evaluated taxonomically. Phages replicate inside the host either by lytic or lysogenic mode after infecting and using the cellular machinery of a bacterium. Phage became an important agent for combating pathogenic bacteria in clinical treatments and its related research gained momentum. However, due to recent rise of bacterial resistance on antibiotics, applications of phage (phage therapy) become an unavoidable option of research. In this dissertation, the advantage and limitations of Bacteriophages for use in humans will be discussed. Furthermore, this dissertation deals with recent development of its application in the areas of biotechnology.
Apoptosis, Senescence, and Cancer
Apoptosis, Senescence and Cancer provides insight into established practices and research into apoptosis and senescence by thoroughly examining novel and emerging techniques and research in the fields of cell death pathways, senescence growth arrest, drugs and resistance, DNA damage response, and other topics which still hold mysteries for researchers.this volume provides basic scientists and clinicians with a deeper and more complete understanding of the cellular responses of malignancies which may determine the effectiveness of treatment.
