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...

1. 1 Scope of the Review This review was intended initially as a reference source for those interested in the origins and fITst descriptions ofthe defective avian sarcoma viruses. Quite a few of these viruses have been characterized in the past few years and their varied nomenclature according to source, discoverer, date of isolation or biological properties could result in some con- fusion among those attempting to follow the literature. Information will be included on the molecular biology of the sarcoma viruses, rather more of which is available than when the review was fITst conceived,...

This book is a comprehensive survey of new and exciting developments regarding the role of DNA methylation in human cancer. Issues related to the mutagenicity of 5-methylcytosine and the increase in the interaction of chemical and physical carcinogens with these residues is discussed. The book summarizes the modulation of viral gene expression and the silencing of tumor suppressor genes and illustrates mechanisms by which the methylation signal is translated into altered chromatin structure. The relationship between DNA methylation and genomic imprinting and cancer, and changes in CpG island...
