In addition to performing its prime function as a vehicle for scientific communications of varied colora­ tions, Molecular and Cellular Biochemistry is again focusing on two subjects which it treats in depth. One of these is a book issue dealing with the transglutaminase reaction. The other is this issue that deals with induction and modulation of enzymes. This is a very broad subject that calls for broader coverage than could be included in one book issue. However, I have elected to include only certain contributions that serve as general examples of the principles involved. There are six articles on enzyme regulation in hepatocyte culture. These include arginase and argino-succi­ nate synthetase, y-glutamyl transferase and plasminogen activitor. Other regulatory enzymes that are discussed are protein kinases, 2,3-bisphosphoglycerate synthetases, carbamoyl phosphate synthetase, heme oxygenase, cytochrome P-450, tyrosine hydroxylase, fatty acid synthetase, acetyl eoA carboxylase, among others. Also included is the regulation of several enzyme messengers RNAs. As in the past, subscribers to the journal will receive this double volume as a continuation of regular issues of the journal Molecular and Cellular Biochemistry. This double volume will also be available separately in the form of a book issue to interested readers through Martinus Nijhoff Publishers. v.A.

Medicinal Chemistry of Anticancer Drugs, Second Edition, provides an updated treatment from the point of view of medicinal chemistry and drug design, focusing on the mechanism of action of antitumor drugs from the molecular level, and on the relationship between chemical structure and chemical and biochemical reactivity of antitumor agents. Antitumor chemotherapy is a very active field of research, and a huge amount of information on the topic is generated every year. Cytotoxic chemotherapy is gradually being supplemented by a new generation of drugs that recognize specific targets on the surface or inside cancer cells, and resistance to antitumor drugs continues to be investigated. While these therapies are in their infancy, they hold promise of more effective therapies with fewer side effects. Although many books are available that deal with clinical aspects of cancer chemotherapy, this book provides a sorely needed update from the point of view of medicinal chemistry and drug design. - Presents information in a clear and concise way using a large number of figures - Historical background provides insights on how the process of drug discovery in the anticancer field has evolved - Extensive references to primary literature

Chapters in this book provide a diverse and comprehensive coverage of this compound class and consequently this publication is a valuable resource for researchers in chemical, pharmaceutical and biological sciences.

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

This book compiles detailed information concerning a dozen of the best known allosteric enzymes, and so allows the comparison of their regulatory mechanisms and the confrontation of these mechanisms with the theoretical models. Stimulating and unexpected ideas emerge from these comparisons and emphasize the importance of developing various methods of investigation such as crystallography, X-ray solution scattering, and the study of fast movements in proteins and site-directed mutagenesis. This book is addressed to students and researchers interested in structure-function relationship in proteins, enzymology and metabolic regulation. It is also a basis for teaching.

This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

This book covers the most recent developments in the analysis of allosteric enzymes and provides a logical introduction to the limits for enzyme function as dictated by the factors that are limits for life. The book presents a complete description of all the mechanisms used for changing enzyme activity. It is extensively illustrated to clarify kinetic and regulatory properties. Eight enzymes are used as model systems after extensive study of their mechanisms. Wherever possible, the human form of the enzyme is used to illustrate the regulatory features.

Nucleotide Metabolism: An Introduction is a textbook exclusively focusing on the study of the aspects of nucleotide metabolism. The book intends to present the chemistry and metabolism of nucleotides, one of the oldest subjects of biochemistry. The text is divided in two parts. Part I considers the general aspects of nucleotide metabolism such as the history of the discovery of nucleotides; functions of nucleotides in cells; and group-transfer reactions during nucleotide metabolism. Part II deals with the synthesis, formation, and conversion of purine ribonucleotides. Biochemists, pharmacologists, and researchers in the fields of medicine and pharmaceuticals will find the book invaluable.
