Bioregulators of Reproduction focuses on the biological regulators of reproductive processes. Discussions are grouped based on sex differentiation and determination, germ cell reproduction, gonadotropins, nonsteroidal gonadal hormones, in vitro fertilization, and post-fertilization. This text is organized into six sections and comprised of 31 chapters, beginning with a discussion on the most important regulatory mechanisms underlying reproduction. The reader is then methodically introduced to the role of the H-Y antigen in primary sex determination, H-Y antigenic determinants of human testis-organizing protein, and how H-Y antibodies confuse antigenic complexes with unaltered self or allo-MHC antigens. The cellular mechanisms of sexual differentiation of the brain, meiosis in female mammals, and interspecies comparisons in molecular reproductive biology are also considered. Other chapters explore the role of haplodins in the ovarian and extraovarian control of meiosis; the link between nucleoprotein transitions and chromatin changes during rat spermatogenesis; and gonadotropin secretion in primates. This book will be of interest to students and scientists in fields ranging from biology and neuroendocrinology to genetics, biochemistry, biophysics, pathology, and zoology.

Cell Biology of the Major Histocompatibility Complex documents the proceedings of a symposium on ""Cell Biology of the Major Histocompatibility Complex"" held at Arden House on the Harriman Campus of Columbia University from June 8 -10, 1984. The meeting was the ninth of the P & S Biomedical Sciences Symposia. The book is organized into five parts. Part I on the structure of MHC molecules includes papers on human histocompatibility antigens; the cloning of human MHC; and organization of the genes of the H-2 complex. Part II on alternate forms of MHC molecules includes studies on the expression of a secreted form of the MHC class I antigen and alternative splicing in the H-2 multigene family. Part III deals with MHC biosynthesis, intracellular transport, and membrane expression. It includes studies on the manipulation of glycans on antigens of the MHC and dynamics of MHC molecules in lymphoid cells. Part IV on homologues of class I MHC molecules covers topics such as Tla expression in normal and malignant cells and the Qa series of antigens. Part V on the association of MHC with antigens includes studies such as histocompatibility molecules as immune response gene products and molecular nature of T-cell recognition of antigen.

Significant recent advances in cell culture technology now permit a detailed biochemical and molecular analysis of differentiation in both normal and tumor cells. These studies are important in attempting to understand the complex factors involved in normal growth and development, as well as the abnormalities associated with carcinogenesis. Mechanisms of Differentiation, Volumes I and II, is comprised of review chapters addressing various topics of current interest in this important area of research. Topics discussed include genes controlling differentiation, changes in gene expression during differentiation, induction of differentiation, induction of differentiation as a mode of action of chemotherapeutic agents, and the effect of cell shape, growth factors and differentiation modulating agents on the differentiated cell phenotype. Mechanisms of Differentiation is valuable to researchers involved in differentiation and development, carcinogenesis, cell biology, chemotherapy, and immunology.

Regulatory T Lymphocytes documents the proceedings of a symposium on ""Regulatory T Lymphocytes"" held at Arden House on the Harriman Campus of Columbia University from June 8-10, 1979. The meeting was the fourth of the P&S Biomedical Sciences Symposia. Starting with the opening address on regulatory T lymphocytes and their antigen receptors, the remainder of the book presents the contributions made by researchers at the symposium. These contributions are organized into seven parts. Part I contains studies T cell receptors. Part II presents studies on T cell subpopulations. Parts III and IV examine helper T cells. Parts V and VI deal with suppressor T cells. Part VII contains papers on regulatory T cell circuits.

Pathobiology of the Endothelial Cell presents the proceedings of the symposium on the "Pathobiology of the Endothelial Cell" held at Arden House, on the Harriman Campus of Columbia University on June 5-7, 1981. The book discusses the endothelial growth regulation; the stimulation of vascular cell growth by macrophage products; and the control of proliferation and differentiation of endothelial cells. The text also describes vessel wall growth control; the implications of angiogenesis in vitro for tumor biology; and the interactions and activation of coagulation proteases. Platelet adhesion and fibrinogen proteolysis; endothelial protein synthesis; prostaglandins, and endothelial cell-cell interactions are also considered. The book further tackles topics on vascular pathobiology. Biologists, pathologists, biochemists, hematologists, oncologists, immunologists, and microbiologists will find the text invaluable.

First multi-year cumulation covers six years: 1965-70.

Cells of Immunoglobulin Synthesis documents the proceedings of a symposium on ""Cells of Immunoglobulin Synthesis"" held at Arden House, on the Harriman Campus of Columbia University from June 9-11, 1978. The meeting was the third of the P & S Biomedical Sciences Symposia. Starting with the opening address on B lymphocyte differentiation and the tolerance problem, the remainder of the book presents the contributions made by researchers at the symposium. These contributions are organized into seven parts. Part I contains studies on immunoglobulin genes, messages, and molecules. Part II presents studies on cellular immunoglobulin production. Part III examines membrane immunoglobulins while Part IV focuses on immunoglobulins as regulatory molecules. Part V deals with lymphocyte hybrids. Part VI examines immunoglobulin idiotypes while Part VII contains papers on the ontogeny of immunoglobulin-synthesizing cells.

CRISPR Genome Surgery in Stem Cells and Disease Tissues focuses uniquely on the clinical applications of CRISPR/Cas9 based technology. Topics include the latest advances in gene editing and its translational applications to various diseases, including retinal degenerative disease, recessively inherited diseases, and dominantly inherited diseases, to name a few. The book's target audience includes researchers, students, clinicians and the general public. This space that is not currently served by any existing resource, so this publication fills a gap in current literature. - Provides a thorough review of CRISPR-Cas9, from discovery to therapy - Covers the latest advances in gene editing and its translational applications to various diseases - Written by global leaders in the fields of gene editing and stem cell therapy

Transfer and Expression of Eukaryotic Genes documents the progress in our understanding of the transfer and expression of eukaryotic genes. This book covers topics organized around three themes: gene expression and its regulation; in vivo gene transfer and development; and viral gene and oncogene systems. This text is divided into three sections encompassing 25 chapters and begins with an overview of the molecular basis of gene expression, with emphasis on transcription complexes that account for transcription control in eukaryotic genes. It then turns to experiments that assess the in vitro stimulatory effect of the SV40 72-bp repeat on specific transcription from heterologous promoter elements using a HeLa whole cell extract. The reader is methodically introduced to the regulation signals and factors of histone gene transcription; transcriptional control of beta-globin and liver-specific genes in mouse cells; and gene transfer in Drosophila and the sea urchin Strongylocentrotus purpuratus. This book also considers the splicing of messenger RNA precursors and the regulation of thymidine kinase enzyme expression, and then concludes with a chapter that describes the activation of the myc oncogene by chromosomal translocation. This book will be of interest to students and researchers in fields ranging from molecular genetics to microbiology, biochemistry, pathology, and immunology.
