Download or read book Nuclear Export of Viral RNAs written by J. Hauber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In eukaryotic cells, the nuclear genome and its transcriptional apparatus is separated from the site of protein synthesis by the nuclear envelope. Thus, a constant flow of proteins and nucleic acids has to cross the nuclear envelope in both directions. This transport in and out of the nucleus is mediated by nuclear pore complexes (NPCs) and occurs in an energy and signal-dependent manner. Thus, nucleocytoplasmic translocation of macro molecules across the nuclear envelope appears to be a highly specific and regulated process. Viruses that replicate their genome in the cell nucleus are therefore forced to develop efficient ways to deal with the intracellulZlr host cell transport machinery. Historically, investigation of Polyomavirus replication allowed identification ofsequences that mediate nuclear import, which led subsequently to our detailed understanding of the cellular factors that are involved in nuclear import. Transport ofmacromolecules in the opposite direction, however, is less well understood. The investigation of retroviral gene expression in recent years pro vided the first insights into the cellular mechanisms that regulate nuclear export. In particular, the detailed dissection of the function of the human immunodeficiency virus type I (HIV-I) Rev trans-activator protein identified CRMI, as a hona fide nuclear export receptor. CRM I appears to be involved in the nucleocytoplasmic translocation of the vast majority of viral and cellular proteins that have subsequently been found to contain a Rev-type leucine-rich nuclear export signal (NES).
Download or read book Structures and Functions of Retroviral RNAs written by Philippe Fosse and published by John Wiley & Sons. This book was released on 2022-09-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: One family of viruses is responsible for the infection of many species of vertebrates. These are the retroviruses whose genomic RNA is used to support genetic information and ensures many essential functions that are required for the formation of an infectious viral particle. These functions depend on structures formed by the folding of the genomic RNA. Structures and Functions of Retroviral RNAs describes the formation of these structures and their specific interactions with nucleic acids and proteins. In light of recent advances in molecular virology, it provides an understanding of the various facets of the retroviral genome. It emphasizes in particular that the study of the structure–function relationship of retroviral RNAs is a driving force behind increased research into HIV-1, the main causal agent of AIDS. Indeed, one of the challenges of pharmacology lies in the exploitation of several targets which allow us to anticipate and stem the emergence of resistance to anti-HIV drugs. The book also presents structures and interactions that may be potential future targets in this regard.

Download or read book Retroviruses written by John M. Coffin and published by CSHL Press. This book was released on 1997 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over 25 years the study of retroviruses has underpinned much of what is known about information transfer in cells and the genetic and biochemical mechanisms that underlie cell growth and cancer induction. Emergent diseases such as AIDS and adult T-cell lymphoma have widened even further the community of investigators directly concerned with retroviruses, a development that has highlighted the need for an integrated understanding of their biology and their unique association with host genomes. This remarkable volume satisfies that need. Written by a group of the field's most distinguished investigators, rigorously edited to provide a seamless narrative, and elegantly designed for clarity and readability, this book is an instant classic that demands attention from scientists and physicians studying retroviruses and the disorders in which they play a role.

Download or read book Translational Control of Gene Expression written by Nahum Sonenberg and published by CSHL Press. This book was released on 2001 with total page 1034 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1996 publication of Translational Control, there has been fresh interest in protein synthesis and recognition of the key role of translation control mechanisms in regulating gene expression. This new monograph updates and expands the scope of the earlier book but it also takes a fresh look at the field. In a new format, the first eight chapters provide broad overviews, while each of the additional twenty-eight has a focus on a research topic of more specific interest. The result is a thoroughly up-to-date account of initiation, elongation, and termination of translation, control mechanisms in development in response to extracellular stimuli, and the effects on the translation machinery of virus infection and disease. This book is essential reading for students entering the field and an invaluable resource for investigators of gene expression and its control.

Download or read book The Threat of Pandemic Influenza written by Institute of Medicine and published by National Academies Press. This book was released on 2005-04-09 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public health officials and organizations around the world remain on high alert because of increasing concerns about the prospect of an influenza pandemic, which many experts believe to be inevitable. Moreover, recent problems with the availability and strain-specificity of vaccine for annual flu epidemics in some countries and the rise of pandemic strains of avian flu in disparate geographic regions have alarmed experts about the world's ability to prevent or contain a human pandemic. The workshop summary, The Threat of Pandemic Influenza: Are We Ready? addresses these urgent concerns. The report describes what steps the United States and other countries have taken thus far to prepare for the next outbreak of "killer flu." It also looks at gaps in readiness, including hospitals' inability to absorb a surge of patients and many nations' incapacity to monitor and detect flu outbreaks. The report points to the need for international agreements to share flu vaccine and antiviral stockpiles to ensure that the 88 percent of nations that cannot manufacture or stockpile these products have access to them. It chronicles the toll of the H5N1 strain of avian flu currently circulating among poultry in many parts of Asia, which now accounts for the culling of millions of birds and the death of at least 50 persons. And it compares the costs of preparations with the costs of illness and death that could arise during an outbreak.
