Import of plasmid DNA into the nucleus is sequence specific.
Nuclear import of plasmid DNA in nondividing cells is a process essential to the success of numerous viral life cycles, gene therapy protocols, and gene expression experiments. Here, intact protein-free SV40 DNA was cytoplasmically injected into cells and its subcellular localization was followed by in situ hybridization. SV40 DNA localized to the nucleus consistent with a mechanism of transpor...
متن کاملCytoplasmic transport and nuclear import of plasmid DNA
Productive transfection and gene transfer require not simply the entry of DNA into cells and subsequent transcription from an appropriate promoter, but also a number of intracellular events that allow the DNA to move from the extracellular surface of the cell into and through the cytoplasm, and ultimately across the nuclear envelope and into the nucleus before any transcription can initiate. Im...
متن کاملExpression of CK8 and CK17, Specific Epithelial Markers, by Oral Squamous Cell Carcinoma Cell Lines
Objectives Oral squamous cell carcinoma (OSCC) is among the most common cancers worldwide. This study aimed to assess the expression of CK8 and CK17 by OSCC cell lines in Iranian patients. Methods This observational study was conducted on three OSCC cell lines with a minimum of 45 passages. Cells isolated from three patients with OSCC were cultured and passaged. Expression of CK8 and CK17 epi...
متن کاملReconstitution of HIV-1 rev nuclear export: independent requirements for nuclear import and export.
The Rev protein of HIV-1 actively shuttles between nucleus and cytoplasm and mediates the export of unspliced retroviral RNAs. The localization of shuttling proteins such as Rev is controlled by the relative rates of nuclear import and export. To study nuclear export in isolation, we generated cell lines expressing a green fluorescent protein-labeled chimeric protein consisting of HIV-1 Rev and...
متن کاملSequence and characterization of cytoplasmic nuclear protein import factor p97
Nuclear location sequence-mediated binding of karyophilic proteins to the nuclear pore complexes is one of the earliest steps in nuclear protein import. We previously identified two cytosolic proteins that reconstitute this step in a permeabilized cell assay: the 54/56-kD NLS receptor and p97. A monoclonal antibody to p97 localizes the protein to the cytoplasm and the nuclear envelope. p97 is e...
