Topics Covered
- Current understanding of the organization of the mammalian cell nucleus and how this organization impacts on gene expression
- in-vivo studies of gene expression as a result of the concerted processes of transcription, mRNA processing, messenger ribonucleoprotein particle (mRNP) export and translation
- studies of spatial and temporal aspects of critical cellular processes within the context of the living cell
- development of a cell system that allows the visualization of a transcription site and its mRNA and protein products directly in living cells
- evaluation of spatial and temporal changes in chromatin structure, mRNA synthesis and factor association/disassociation during the transition from a transcriptionally inactive to an active state
- understanding of the in-vivo dynamics of gene expression will provide the basis from which to elucidate spatial and/or temporal alterations that occur in cells associated with various disease states
