This book was released on 2012-12-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: A workshop on "MOLECULAR ASPECTS OF MYELOID STEM CELL DEVELOPMENT" was held at the Historic Inns in Annapolis, MD during April 30-May 3, with approximately 70 persons attend ing. The enormous success of this meeting was attributable to the recent outburst of information generated from two areas of study: transcriptional regulation of developmentally important myeloid genes and molecular dissection of chromosomal abnormalities in human myeloid leukemias. It was reassuring that studies of normal myelopoiesis and abnormal myelopoiesis, as observed in dys plasias and neoplasia, are revealing several interrelated mechan isms of gene regulation. However, great challenges await us as we try to determine how these and other mechanisms in this intricate system orchestrate the ultimate fate of cells e. g. proliferation, differentiation or apoptosis. This volume of Current Topics in Micro biology encapsulates many of the key aspects of the workshop summarizing research over the past few years on the ontogeny and pathology of myeloid cells. Investigations into the complex process of normal myeloid cell . maturation were first made possible through development of in vitro clonigenic assays. These established the relationships of colony stimulating factors, interleukins and their combinations to the specific fates of myeloid progenitors derived from the bone , marrow and spleen. Molecular studies became feasible, however, through the later establishment of several cell culture systems in volving immortalized cells which, under the proper induction, could fairly accurately recapitulate the myelopoietic process.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this thesis is to explore the potential application of leukemia stem cell (LSC) properties for improving the treatment and management of adults with acute myeloid leukemia (AML), solidifying the clinical relevance of functional stem cell frequency estimates from xenotransplantation assays to human disease, and gaining insight into the gene regulatory logic underlying blood stem cells. Conventional risk stratification schemes in AML do not account for the leukemia initiating capacity of LSC within patient samples even though mounting evidence indicates its importance in the etiology and pathogenesis of AML. This may be attributed, at least in part, to insufficient data in support of the definitive relevance of xenografts (the gold standard assay for detecting LSC) to human disease. Instead, clinical schemes have focused on an ever-increasing number of genomic lesions for sorting patients into incrementally refined risk categories as newer technologies and larger study cohorts enable higher resolution and more complete capture of the continuum of genomic variation. Here, the derivation of the LSC17 gene expression score resulted in the first LSC-based diagnostic tool that complements and refines current risk assessment schemes, setting the stage for enhancing the overall accuracy of prognostic and predictive models in the clinic. The backbone of AML treatment has largely remained unchanged since the 1970s, and is curative for.

This book was released on 2007 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite a rapidly evolving understanding of the murine HSC niche, its signalling components, and the mechanisms utilized for trafficking to these sites, less is known of the microenvironmental requirements for human HSCs, while the gap in understanding for LSCs is even more pronounced. We demonstrate that administration of an activating anti-CD44 antibody impaired in vivo AML cell homing and facilitated eradication of these cells, including serially transplantable SL-IC in pre-engrafted NOD/SCID mice. Our results highlight CD44 as a key regulator of AML-LSC function, essential for their trafficking to microenvironmental niches and for maintaining their primitive state. The potential importance of microRNAs (miRNA) in the pathogenesis of cancer and in stem cell regulation prompted our investigation into the involvement of miRNAs in the initiation and/or maintenance of AML-LSC. Here we use global miRNA profiling of purified stem, progenitor and mature cell subfractions from primary AML samples to demonstrate the existence of a unique LSC-specific miRNA signature. We also show that mir-155, a miRNA highly expressed at elevated levels in human lymphomas, is also dysregulated in human AML and may play a functional role in maintaining the developmental status and abnormal growth properties of these leukemias. Transplantation models have provided valuable tools with which to investigate hematopoiesis and have been essential in elucidating the hierarchical nature of the murine blood system. In particular, these assays permit the study of hematopoietic stem cells (HSCs), unique in their capacity to re-establish enduring donor hematopoiesis. Similarly, the use of immunodeficient SCID and NOD/SCID mouse strains as recipients for human hematopoietic cells has facilitated the study of human SCID-repopulating cells and SCID-leukemia initiating cells (SL-ICs), responsible for initiating and perpetuating normal and malignant hematopoiesis respectively. Here we use lentiviruses to transduce acute myeloid leukemia (AML) SL-ICs with high efficiency, enabling in vivo tracking of individual SL-ICs. We show that the leukemia stem cell (LSC) compartment is heterogeneous with the existence of distinct classes that differ in proliferation and self-renewal capacity. The finding of a similar functional hierarchy within the normal HSC and LSC compartments represents compelling evidence of a stem cell origin for AML.

Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.

Book excerpt: 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.
