This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the eukaryotic cell nucleus, chromatin is organized into higher-order structures through hierarchical levels of folding and coiling. Active genes are contained in chromatin domains with a more "open" conformation that is preferentially sensitive to DNase 1 digestion compared to inactive chromatin. The spatial organization of chromatin is maintained by the nuclear matrix, the major structural component of the nucleus. Chromosomal DNA is organized into supercoiled loops anchored at their bases to the nuclear matrix, and in most cases examined, active genes are located at or near the base of the loops. -- I have examined the DNase 1 sensitivity of the integrated viral sequences of four adenovirus type 5-transformed cell lines, and the organization of these sequences relative to the nuclear matrix. DNase 1 sensitivity was analysed by digesting nuclei with DNase 1 and monitoring the disappearance of virus-specific restriction fragments by Southern blotting and hybridization. In each cell line, the integrated viral sequences were in a conformation typical of active chromatin, i.e. they were preferentially sensitive to DNase 1 compared to inactive chromatin. The DNase 1 sensitive region included not only the active transforming (E1) genes, but extended into the adjacent inactive viral sequences. Thus, the integrated viral sequences were contained within active chromatin domains. -- In addition to these extended domains, DNase 1 hypersensitive sites were detected in the E1A 5'-flanking sequences. These sites were mapped to sequences previously shown to contain the E1A transcriptional enhancers and binding sites for cellular transcription factors. Therefore, the DNase 1 hypersensitive sites likely reflect alterations in local chromatin structure associated with regulation of transcription of the integrated E1A genes. -- The organization of the integrated viral sequences relative to the nuclear matrix was analysed by assessing the matrix associated and non-associated DNA fractions for their content of viral sequences by Southern blotting and hybridization. There was no enrichment or depletion of the viral sequences in either of these fractions relative to total unfractionated DNA, consistent with a random organization relative to the nuclear matrix. However, control studies indicated that these results may be due to the conditions used to isolate the nuclear matrix DNA fractions. - (Keywords: adenovirus type 5; chromatin domain; DNase 1 sensitivity; hypersensitive sites; nuclear matrix.).

Download or read book Nuclear Structure and Gene Expression written by R. Curtis Bird and published by Elsevier. This book was released on 1996-11-28 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Structure and Gene Expression assimilates the contributions of genome organization and of the components of the nuclear matrix to the control of DNA and RNA synthesis. Nuclear domains which accommodate DNA replication and gene expression are considered in relation to short-term developmental and homeostatic requirements as well as to long-term commitments to phenotypic gene expression in differentiated cells. Consideration is given to the involvement of nuclear structure in gene localization as well as to the targeting and concentration of transcription factors. Aberrations in nuclear architecture associated with and potentially functionally related to pathologies are evaluated. Tumor cells are described from the perspective of the striking modifications in both the composition and organization of nuclear components. Nuclear Structure and Gene Expression presents concepts as well as experimental approaches, which define functionality of nuclear morphology.* Mechanisms of interaction between nuclear structure and genes* Gene expression regulation by elements of the nuclear matrix* How nuclear structure exerts a regulatory effect on other aspects of cell function/physiology

Download or read book Monte Carlo Simulation in Statistical Physics written by Kurt Binder and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: When learning very formal material one comes to a stage where one thinks one has understood the material. Confronted with a "realiife" problem, the passivity of this understanding sometimes becomes painfully elear. To be able to solve the problem, ideas, methods, etc. need to be ready at hand. They must be mastered (become active knowledge) in order to employ them successfully. Starting from this idea, the leitmotif, or aim, of this book has been to elose this gap as much as possible. How can this be done? The material presented here was born out of a series of lectures at the Summer School held at Figueira da Foz (Portugal) in 1987. The series of lectures was split into two concurrent parts. In one part the "formal material" was presented. Since the background of those attending varied widely, the presentation of the formal material was kept as pedagogic as possible. In the formal part the general ideas behind the Monte Carlo method were developed. The Monte Carlo method has now found widespread appli cation in many branches of science such as physics, chemistry, and biology. Because of this, the scope of the lectures had to be narrowed down. We could not give a complete account and restricted the treatment to the ap plication of the Monte Carlo method to the physics of phase transitions. Here particular emphasis is placed on finite-size effects.

Download or read book Nuclear Chromosomal and Genomic Architecture in Biology and Medicine written by Malgorzata Kloc and published by Springer Nature. This book was released on 2022-11-08 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews the latest research on the functional implications of nuclear, chromosomal and genomic organization and architecture on cell and organismal biology, and development and progression of diseases. The architecture of the cell nucleus and non-random arrangement of chromosomes, genes, and the non-membranous nuclear bodies in the three-dimensional (3D) space alters in response to the environmental, mechanical, chemical, and temporal cues. The changes in the nuclear, chromosomal, or genomic compaction and configuration modify the gene expression program and induce or inhibit epigenetic modifications. The intrinsically programmed rearrangements of the nuclear architecture are necessary for cell differentiation, the establishment of cell fate during development and maturation of tissues and organs including the immune, muscle, and nervous systems. The non-programmed changes in the nuclear architecture can lead to fragmentation of the nucleus and instability of the genome and thus cause cancer. Microbial and viral infections can lead to a clustering of centromeres, telomeres and ribosomal DNA and alter the properties of the nuclear membrane, allowing large immobile macromolecules to enter the nucleus. Recent advances in next-generation sequencing technologies combined with nucleus/chromosome conformation capture, super-resolution imaging, chromosomal contact maps methods, integrative modeling, and genetic approaches, are uncovering novel features and importance of nuclear, chromosomal and genomic architecture. This book is an interesting read for cell biologists, researchers studying the structure and function of chromosomes, and anyone else who wants to get an overview of the field of nuclear, chromosomal and genomic architecture.
