Cloning And Characterization Of Novel Members Of The Rel Nf Kb Family Of Transcription Factors

Depite the rapid expansion of the field of biophysics, there are very few books that comprehensively treat specific topics in this area. Recently, the field of single molecule biophysics has developed very quickly, and a few books specifically treating single molecule methods are beginning to appear. However, the promise of single molecule biophysics is to contribute to the understanding of specific fields of biology using new methods. This book would focus on the specific topic of the biophysics of DNA-protein interactions, and would include the use of new approaches, including both bulk methods as well as single molecule methods. This would make the book attractive to anyone working in the general area of DNA-protein interactions, which is of course a much wider market than just single molecule biophysicists or even biophysicists. The subject of the book will be the biophysics of DNA-protein interactions, and will include new methods and results that describe the physical mechanism by which proteins interact with DNA. For example, there has been much recent work on the mechanism by which proteins search for specific binding sites on DNA. A few chapters will be devoted to experiments and theory that shed light on this important problem. We will also cover proteins that alter DNA properties to facilitate interactions important for transcription or replication. Another section of the book will cover the biophysical mechanism by which motor proteins interact with DNA. Finally, we will cover larger protein-DNA complexes, such as replication forks, recombination complexes, DNA repair interactions, and their chromatin context.

Focuses on recent key discoveries made relating to the cell cycle and its regulation - a critical new horizon in therapeutics. Research into all aspects of cell cycle regulation has undergone explosive growth during the past decade due to the powerful techniques of molecular biology. An overall view of the cellular processes, both at the enzymatic and genetic level, has been identified in continually finer detail, as described inside this text. This has enabled significant progress in the identification of drugs capable of acting on specific components of the cell cycle, with the result that we may soon have the ability to manipulate the cell cycle pharmacologically. The potential impact on clinical conditions such as cancer, hematopoiesis, angiogenesis, inflammation, organ remodelling and apoptosis is vast. Originating from presentations at the Eighth SmithKline Beecham Pharmaceuticals United States Research Symposium, each chapter in this volume is written by an opinion leader in the field.

Cells have evolved multiple strategies to adapt the composition and quality of their protein equipment to needs imposed by changes in intra- and extracellular conditions. The appearance of pro teins transmit ting novel functional properties to cells can be controlled at a transcrip tional, posttranscriptional, translational or posttranslational level. Extensive research over the past 15 years has shown that transcriptional regulation is used as the predominant strategy to control the production of new proteins in response to extracellular stimuli. At the level of gene transcription, the initiation ofmRNA synthesis is used most frequently to govern gene expression. The key elements controlling transcription initiation in eukaryotes are activator proteins (transactivators) that bind in a sequence-specific manner to short DNA sequences in the of genes. The activator binding sites are elements of larger proximity control units, ca lied promoters and enhancers, which bind many distinct proteins. These may synergize or negatively cooperate with the activators. The do novo binding of an activator to DNA or, if already bound to DNA, its functional activation is what ultimately turns on a high-level expression of genes. The activity of transactivators is controlled by signalling pathways and, in some cases, transactivators actively partici pate in signal transduction by moving from the cytoplasm into the nuc1eus. In this first volume of Inducible Gene Expression, leading scientists in the field review six eukaryotic transactivators that allow cells to respond to various extracellular stimuli by the expression of new proteins.

Transcription Factors Normal and Malignant Development of Blood Cells Katya Ravid and Jonathan Licht The role of transcription factors in activating specific genes in blood cells is an important facet of hematopoiesis. Equally important, however, is the pursuit of genes rearranged and aberrantly activated in leukemias (blood malignancies). Transcription Factors: Normal and Malignant Development of Blood Cells focuses on those major transcription factors involved in activation of lineage-specific gene expression during normal versus malignant development of specific blood lineages, as revealed from gene promoter studies, knockout of transcription factors in mice models, and the identification and characterization of chromosomal rearrangement in human blood leukemias. This complete digest of current transcription factor data offers comprehensive coverage of the myriad of transcription factors in blood cell development, composed by established experts in the field. In addition to updating the reader on the connection between chromosomal translocations involving transcription factors and cellular transformation leading to leukemia, Transcription Factors also reviews such subjects as: * Transcription factors and the megakaryocytic, myeloid, and erythroid lineages * Leukemias due to chromosomal translocations involving gene encoding transcription factors * Oncogenesis and hematopoiesis * In vivo studies of transcription factors implicated in hematopoiesis * And much more Appealing to both the researcher and the clinician in the field of hematology, Transcription Factors is a timely presentation of cell lineage development and sheds light on the processes involved in the development of specific leukemias. Providing insight into the study of transcription factors, readers will gain an understanding of mechanisms that lead to normal lineage commitment and terminal differentiation.
