Available in PDF, EPUB and Kindle. Book excerpt: Molecular Biology of Plant Tumors provides an opportunity to learn in detail about the latest insights into the mechanism of transformation of plant cells by Agrobacterium tumefaciens. The study of the molecular mechanism responsible for the crown gall phenomenon (induced by Agrobacterium tumefaciens) illustrates the point that the fundamental study of the cause(s) and mechanism(s) of abnormal growth might be one of the most efficient ways to understand cellular differentiation and the molecular basis of gene expression. The book is organized into three parts that contain research on abnormal plant growth, crown gall tumors, and potential vectors for genetic engineering in agriculture. The genetic structure responsible for the neoplasmic transformation of plant cells in crown galls is a bacterial plasmid (called Ti for tumor-inducing). Research described in this volume demonstrates that these Ti plasmids were designed by evolution as natural gene vectors with which some bacteria can introduce active genes into plants. These transferred genes are maintained by integration in the plant genome and their expression is directly or indirectly responsible for the tumorous growth pattern.

Available in PDF, EPUB and Kindle. Book excerpt: With the aim of providing an international forum for the communication of both the basic and clinical aspects of molecular and cellular biology of cancer, a NATO ASl was held in Porto Carras, Halkidiki, Greece, September 1-12, 1995. The principles as well as recent developments in tumor biology were discussed in depth, with emphasis on the regulation of the cell cycle, differentiation, programmed cell death (apoptosis) and genetics of cancer. This book constitutes the proceedings of that meeting. Specifically, the following areas were addressed: (a) enzymes and proteins (cyclins) that control the cell cycle, as well as the role of m as gene in meiosis and transformation; (b) the structural basis for specificity in protein-tyrosine kinase reactions; (c) the differentiation of normal as well as neoplastic cells with respect to molecular mechanism(s) by which chemical agents or growth factors trigger maturation; (d) phenotypic and genetic aspects of apoptosis; (e) the role of growth factors, like IGF-l, FGF, TN, IL-6, etc. , in cell cycle regulation, apoptosis (cell death) and senescence; (f) molecular mechanisms of transcriptional activation of globin genes and stability of mRNAs related to growth proteins and iron metabolism; (g) the cellular and molecular biology of bone marrow hemopoiesis; and (h) neurotrophic factors and the generation of cellular diversity in the central nervous system. It was obvious from the studies presented that neoplastic cell growth, differentiation and apoptosis in many cell types are regulated at several levels.

Available in PDF, EPUB and Kindle. Book excerpt: The Ninth Annual Pezcoller Symposium entitled "The Biology of Tumors" was held in Rovereto, Italy, June 4-7, 1997. It focused on the genetic mechanisms underlying het erogeneity of tumor cell populations and tumor cell differentiation, on interactions be tween tumor cells and cells of host defenses, and the mechanisms of angiogenesis. With presentations at the cutting edge of progress and stimulating discussions, this symposium addressed issues related to phenomena concerned with cell regulation and cell interactions as determined by activated genes through the appropriate and timely media tion of gene products. Important methodologies that would allow scientists to measure dif ferentially genes and gene products and thus validate many of the mechanisms of control currently proposed were considered, as were the molecular basis of tumor recognition by the immune system, interactions between cells and molecular mechanisms of cell regula tion as they are affected by or implemented through these interactions. The molecular and cellular mechanisms of tumor vascularization were also discussed. It was recognized that angiogenesis provides a potential site of therapeutic intervention and this makes it even more important to understand the mechanisms underlying it. We wish to thank the participants in the symposium for their substantial contribu tions and their participation in the spirited discussions that followed. We would also like to thank Drs.
Download or read book Agrobacterium Tumefaciens written by Eugene W. Nester and published by American Phytopathological Society. This book was released on 2005 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This anthology traces the fascinating progress from plant pathology to biotechnology through 38 scientific papers on Agrobacterium, published over the past century. Included are the seminal scientific papers on the biology and application of Agrobacterium with introductory commentaries mostly by those involved in the original work. The commentaries give background to the papers and explain the problems faced and the techniques used, providing insight into the way fundamental research progresses.Agrobacterium tumefaciens has played a major role in the astounding advances that have been made over the past several decades in the areas of plant genetics, plant molecular biology, and plant genetic engineering. The papers included in this book were integral to the current understanding of the interaction of Agrobacterium with its hosts, its development into a major player in the genetic engineering of plants, and the biological control of crown gall.Agrobacterium tumefaciens: From Plant Pathology to Biotechnology is divided into five sections. The first section begins with 1904 when Erwin F. Smith began detailed work on crown gall and considered it to be a plant pathological problem. It explores many of the biological discoveries made over the past century, including the pivotal moment when Armin C. Braun discovered that crown gall was a plant cancer. Other papers cover the beginnings of T-DNA research and the development of vectors to improve the process of transferring T-DNA from bacterium to plant cell. The second section delves further into vector systems and genetic coding for disease and insect resistance, exploring the evolution of genetic engineering in crops.The final three sections deal with themes developed from crown gall studies, including ?quorum sensing? or population density, the DNA sequencing of one strain of A. tumefaciens, and the first genetically engineered organism, strain K1026, released for commercial use.According to Editor, Eugene Nester, ?This book should serve as a testimony to the 100 years of research on this remarkable organism, as well as to an international group of investigators who helped reveal secrets of this natural genetic engineer.? Students, professors, plant pathologists, microbiologists, or anyone interested in research and/or the history of plant pathology and biotechnology, will find this collection of papers an intriguing read.From the Preface: ??the journey is not over. As the commentary by Paul Hooykaas indicates, it looks as though T-DNA will insert into any cell, be it plant, fungal or even mammalian. Is there a possibility of using Agro?bacterium in gene therapy? Will Agrobacterium prove to be as useful a tool in fungal genetics as it has been in plant genetics? Its potential is mind-boggling.?
Download or read book Agrobacterium From Biology to Biotechnology written by Tzvi Tzfira and published by Springer Science & Business Media. This book was released on 2007-12-25 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agrobacterium is a plant pathogen which causes the “crown-gall” disease, a neoplastic growth that results from the transfer of a well-defined DNA segment (“transferred DNA”, or “T-DNA”) from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications. The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability of neoplastic cells to survive exposure to various chemotherapeutic drugs represents the main obstacle to successful cancer chemotherapy. This book deals with a particular type of resistance in tumor cells that represents a single but especially important aspect of the multifaceted problem of cancer drug resistance. This type of resistance, known as multidrug or pleiotropic drug resistance, is characterized by cross-resistance of cells to several different classes of cytotoxic drugs, including some of the most commonly used anticancer agents. Over the last several years, there has been a veritable explosion of genetic, biochemical, and clinical information on multidrug resistance, which followed the identification and cloning of the genes responsible for this phenotype and the isolation of monoclonal antibodies against P-glycoproteins, the products of these genes. Elucida tion of the molecular mechanism of multidrug resistance has led to the formulation of novel approaches to the prediction of tumor response to chemotherapeutic drugs and increasing the efficacy of cancer therapy. Analysis of the structure and function of P glycoproteins from multidrug-resistant mammalian cells has also established a prototype for a novel class of eukaryotic membrane proteins, which have now been associated with a variety of transport processes in different organisms. This book summarizes the results of molecular biological, pharmacological, bio chemical, cytogenetic, immunological, and pathological studies on multidrug resistance in mammalian cells. Most of the chapters deal at least to some extent with the structure and expression of P-glycoprotein and its role in multidrug resistance.
Download or read book Biology of Tumors Surfaces Immunology and Comparative Pathology written by Frederick Becker and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: As was shown in the first two volumes of this series, great strides have been made in identifying many of the agents or classes of substances responsible for carcinogenesis and in delineating their interactions with the cell. Clearly, the aim of such studies is that, once identified, these agents can be eliminated from the environment. Yet, despite these advances and the elimination of some important carcinogenic agents, one major problem exists. It is a constant monitor of all oncologic study and diminishes the importance of every experiment and of every clinical observation. As we noted earlier, that problem is our inability to define the malignant cell. It is through studies of the fundamental biology of tumors that we seek this definition. A vast amount of information has been gathered which describes what this cell does and-to a lesser extent-how it does it. But the why evades us. We have been unable to define the malignant cell, save in broad terms by comparing it to its normal counterpart. The major problem appears to be that the malignant cell does so much. It is a chimera, mystifyingly composed of normal activities and structures, of phenotypic schizophrenia with embryonic, fetal, and adult charac teristics and, occasionally, a hint of an unclassifiable capacity unique to malignant cells.
