Heat shock proteins are emerging as important molecules in the development of cancer and as key targets in cancer therapy. These proteins enhance the growth of cancer cells and protect tumors from treatments such as drugs or surgery. However, new drugs have recently been developed particularly those targeting heat shock protein 90. As heat shock protein 90 functions to stabilize many of the oncogenes and growth promoting proteins in cancer cells, such drugs have broad specificity in many types of cancer cell and offer the possibility of evading the development of resistance through point mutation or use of compensatory pathways. Heat shock proteins have a further property that makes them tempting targets in cancer immunotherapy. These proteins have the ability to induce an inflammatory response when released in tumors and to carry tumor antigens to antigen presenting cells. They have thus become important components of anticancer vaccines. Overall, heat shock proteins are important new targets in molecular cancer therapy and can be approached in a number of contrasting approaches to therapy.

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

This is the third volume in the new World Health Organization series on histological and genetic typing of tumours. Tumours of the haematopoietic and lymphoid tissues are covered. This was a collaborative project of the European Association for Haematolpathology and the Society for Haematopathology and others. The WHO classification is based on the principles defined in the Revised European-American Classification of Lymphoid Neoplasms (REAL) classification. Over 50 pathologists from around the world were involved in the project and proponents of all major lymphoma and leukaemia classifications have agreed to accept the WHO as the standard classification of haematological malignancies. So this classification represents the first true world wide concensus of haematologic malignancies. Colour photographs, magnetic resonance and ultrasound images and CT scans are included.

Breaking Tolerance to Pancreatic Cancer Unresponsiveness to Chemotherapy edited by Dr. Nagaraju, PhD., DSc. focuses on overriding the resistance from chemotherapeutic drugs with a broader range of treatment options. It particularly focuses on stroma, tumor microenvironment, stem cells, stellate cells, transcription factors, growth factors, and important signaling pathways. This volume discusses topics such as pancreatic cancer biology, current therapeutic options, EMT, chemotherapy resistance mechanisms, and genetic manipulations and natural products to enhance the sensitivity of pancreatic cancer to chemotherapy. Additionally, it discusses small targeted molecules and pancreatic cancer trials, and nanotechnology-based drug delivery. Breaking Tolerance to Pancreatic Cancer Unresponsiveness to Chemotherapy is a valuable source for researchers and advanced students in cancer and oncology as well as clinicians and medical students who are interested in learning more about ways to break pancreatic cancer resistance to chemotherapy. - Modulates the biologic properties of stroma in pancreatic cancer by targeting the several chemotherapy resistance mechanisms to impede their malignant property by introducing new strategies and drugs - Provides information about on-going research as well as clinical data on pancreatic cancer and detailed descriptions about therapeutic options for easy understanding - Utilizes full color figures to help the understanding of the content and tables for easy comparison of information as well as quick access to it

Kinase drug discovery remains an area of significant interest across academia and in the pharmaceutical industry. There are now around 13 FDA approved small molecule drugs which target kinases and many more compounds in various stages of clinical development. Although there have been a number of reviews/publications on kinase research, this book fills a gap in the literature by considering the current and future opportunities and challenges in targeting this important family of enzymes. The book is forward-looking and identifies a number of hot topics and key areas for kinase drug discovery over the coming years. It includes contributions from highly respected authors with a combined experience in the industry of well over 200 years, which has resulted in a book of great interest to the kinase field and across drug discovery more generally. Readers will gain a real insight into the huge challenges and opportunities which this target class has presented drug discovery scientists. The many chapters cover a wide breadth of topics, are well written and include high quality colour and black and white images. Topics covered include an outline of how medicinal chemistry has been able to specifically exploit this unique target class, along with reflections on the mechanisms of kinases inhibitors. Also covered is resistance to kinase inhibitors caused by amino acid mutations, case studies of kinase programs and reviews areas beyond protein kinases and beyond the human kinome. Also described are modern approaches to finding kinase leads and the book finishes with a reflection of how kinase drug discovery may progress over the coming years.

The PI3Ks control many key functions in immune cells. PI3Ks phosphorylate PtdIns(4,5)P2 to yield PtdIns(3,4,5)P3. Initially, PI3K inhibitors such as Wortmannin, LY294002 and Rapamycin were used to establish a central role for Pi3K pathway in immune cells. Considerable progress in understanding the role of this pathway in cells of the immune system has been made in recent years, starting with analysis of various PI3K and Pten knockout mice and subsequently mTOR and Foxo knockout mice. Together, these experiments have revealed how PI3Ks control B cell and T cell development, T helper cell differentiation, regulatory T cell development and function, B cell and T cell trafficking, immunoglobulin class switching and much, much more. The PI3Kd inhibitor idelalisib has recently been approved for the treatment of B cell lymphoma. Clinical trials of other PI3K inhibitors in autoimmune and inflammatory diseases are also in progress. This is an opportune time to consider a Research Topic considering when what we have learned about the PI3K signalling module in lymphocyte biology and how this is making an impact on clinical immunology and haematology.

This book orchestrates the differential fields of technology in order to create a new era of the study of reverse chemical genetics. It introduces fundamental resources as well as the modification of these resources by recent molecular technologies.
