Book excerpt: Elucidating Mechanisms of Eukaryotic Genetic Expression by Studying Animal Viruses AARON 1. SHATIGN* Eukaryotic genetic expression is carefully regulated. Normal cell growth and division, tis sue differentiation, and organism development all depend on a strictly ordered progres sion of specific events. Perturbation of the control of these processes, for example by ex posure to harmful chemicals or infection with viruses leads to aberrant forms of meta bolism, often resulting in malignancies and cell death. One of the most challenging problems in biology is to derme at the molecular level the mechanisms that govern gene function in higher organisms, including ultimately man. This goal serves to unify the diverse efforts of many investigators, whether studying the precise patterns of embryo genesis, the loss of control that occurs during neoplastic growth or the redirection of biosynthetic pathways in virus-infected cells. Recently there has been remarkable and exciting progress toward understanding the molecular biology of eukaryotic expression. Much of this rapidly increasing new infor mation has come from studies of animal virus systems. Just as investigations of the relatively simple, rapidly assayed, and easily manipulated bacteriophages lead to basic discoveries about prokaryotic cells, analyses of animal viruses and their interactions with host cells have provided fundamental information about how eukaryotic nucleic acids are organized for regulated replication, transcription, and translation. For example, the small genome of SV , like cellular DNA in chromatin, is associated with histones to 40 form nucleosomal arrays (Griffin 1975).

Book Synopsis The Epstein-Barr Virus by : M. A. Epstein
Download or read book The Epstein-Barr Virus written by M. A. Epstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Epstein-Barr virus was discovered 15 years ago. Since that time an immense body of information has been accumu lated on this agent which has come to assume great signifi cance in many different fields of biological science. Thus, the virus has very special relevance in human medicine and oncology, in tumor virology, in immunology, and in mole cular virology, since it is the cause of infectious mononu cleosis and also the first human cancer virus, etiologically related to endemic Burkitt's lymphoma and probably to nasopharyngeal carcinoma. In addition, continuous human lymphoid cell lines initiated and maintained by the transform ing function of the virus genome provide a laboratory tool with wide and ever-growing applications. Innumerable papers on the Epstein-Barr virus have ap peared over recent years and reports of work with this agent now constitute a veritable flood. The present book provides the first and only comprehensive, authoritative over-view of all aspects of the virus by authors who have been the original and major contributors in their particular disciplines. A complete and up-to-date survey of this unique and important agent is thus provided which should be of great interest to experts, teachers, and students engaged in cancer research, virology, immunology, molecular biology, epide miology, and cell culture. Where topics have been dealt with from more than one of these viewpoints, some inevitable overlap and duplication has resulted; although this has been kept to a minimum, it has been retained in some places because of positive usefulness.

Book Synopsis Epstein-Barr Virus Late Gene Regulation by : Reza Djavadian
Download or read book Epstein-Barr Virus Late Gene Regulation written by Reza Djavadian and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epstein-Barr virus lytic replication is accomplished by an intricate cascade of gene expression that integrates viral DNA replication and structural protein synthesis. Most genes encoding structural proteins exhibit "true" late kinetics - their expression is strictly dependent on lytic DNA replication. Recently, the EBV BcRF1 gene was reported to encode a TATA box binding protein homolog, which preferentially recognizes the TATT sequence found in true late gene promoters. BcRF1 is one of seven EBV genes with homologs found in other [small beta]- and [small gamma]-, but not in [small alpha]-herpesviruses. Using EBV BACmids, we systematically disrupted each of these "[small beta][small gamma]" genes. We found that six of them, including BcRF1, exhibited an identical phenotype: intact viral DNA replication with loss of late gene expression. The proteins encoded by these six genes have been found by other investigators to form a viral protein complex that is essential for activation of TATT-containing reporters in EBV-negative HEK293 cells. Unexpectedly, in EBV infected HEK293 cells, we found that TATT reporter activation was weak and non-specific unless an EBV origin of lytic replication (OriLyt) was present in cis. Using two different replication-defective EBV genomes, we demonstrated that OriLyt-mediated DNA replication is required in cis for TATT reporter activation and for late gene expression from the EBV genome. We further demonstrate by fluorescence in situ hybridization that the late BcLF1 mRNA localizes to EBV DNA replication factories. These findings support a model in which the [small beta][small gamma] gene-encoded viral pre-initiation complex (vPIC) mediates late gene transcription from newly replicated viral DNA. While this model explains the dependence of late gene transcription on lytic DNA replication, it does not account for this dependence in [small alpha]-herpesviruses nor for recent reports that some EBV late genes are transcribed independently of vPIC. To rigorously define which transcription start sites (TSS) are dependent on viral lytic DNA replication or the [small beta][small gamma] complex, we performed Cap Analysis of Gene Expression (CAGE)-seq on cells infected with wildtype EBV or EBV mutants defective for DNA replication, [small beta][small gamma] function, or lacking an origin of lytic replication (OriLyt). This approach identified 16 true-late, 32 early, and 16 TSS that are active at low levels early and are further upregulated in a DNA replication-dependent manner (leaky late). Almost all late gene transcription is vPIC-dependent, with BCRF1 (vIL10), BDLF2, and BDLF3 transcripts being notable exceptions. We present evidence that leaky late transcription is not due to a distinct mechanism, but results from superimposition of the early and late transcription mechanisms at the same promoter. Our results represent the most comprehensive characterization of EBV lytic gene expression kinetics reported to date and suggest that most, but not all EBV late genes are vPIC-dependent

This book was released on 2010-03-10 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature on recoding is scattered, so this superb book ?lls a need by prov- ing up-to-date, comprehensive, authoritative reviews of the many kinds of recoding phenomena. Between 1961 and 1966 my colleagues and I deciphered the genetic code in Escherichia coli and showed that the genetic code is the same in E. coli, Xenopus laevis, and guinea pig tissues. These results showed that the code has been c- served during evolution and strongly suggested that the code appeared very early during biological evolution, that all forms of life on earth descended from a c- mon ancestor, and thus that all forms of life on this planet are related to one another. The problem of biological time was solved by encoding information in DNA and retrieving the information for each new generation, for it is easier to make a new organism than it is to repair an aging, malfunctioning one. Subsequently, small modi?cations of the standard genetic code were found in certain organisms and in mitochondria. Mitochondrial DNA only encodes about 10–13 proteins, so some modi?cations of the genetic code are tolerated that pr- ably would be lethal if applied to the thousands of kinds of proteins encoded by genomic DNA.
