Transcriptional targeting in renal cancer cell lines via the human CXCR4 promoter.
Metastatic renal cell carcinoma (RCC) is often resistant to standard treatment, thereby requiring new therapeutic strategies. In this regard, tumor cell migration and metastasis have recently been shown to be regulated by chemokines and their respective receptors (e.g., SDF-1alpha/CXCR4). In the context of RCC, up-regulation of CXCR4 expression is closely related to the development of invasive ...
متن کاملTranscriptional Targeting of Primary and Metastatic Tumor Neovasculature by an Adenoviral Type 5 Roundabout4 Vector in Mice
New approaches targeting metastatic neovasculature are needed. Payload capacity, cellular transduction efficiency, and first-pass cellular uptake following systemic vector administration, motivates persistent interest in tumor vascular endothelial cell (EC) adenoviral (Ad) vector targeting. While EC transductional and transcriptional targeting has been accomplished, vector administration approa...
متن کاملTargeting gene expression to specific cells of kidney tubules in vivo, using adenoviral promoter fragments
Although techniques for cell-specific gene expression via viral transfer have advanced, many challenges (e.g., viral vector design, transduction of genes into specific target cells) still remain. We investigated a novel, simple methodology for using adenovirus transfer to target specific cells of the kidney tubules for the expression of exogenous proteins. We selected genes encoding sodium-depe...
متن کاملReplication of an adenoviral vector controlled by the human telomerase reverse transcriptase promoter causes tumor-selective tumor lysis.
Telomerase reactivation is a critical step for tumorigenesis, allowing cancer cells to proliferate indefinitely. Taking advantage of this property, we generated an adenovirus vector in which E1 gene expression, and therefore viral replication, is under control of the human telomerase reverse transcriptase (hTERT) promoter. This vector, referred to as Ad5-hTERT-E1, replicated in cancer cells and...
متن کاملAdenoviral Vector Driven by a Minimal Rad51 Promoter Is Selective for p53-Deficient Tumor Cells
BACKGROUND The full length Rad51 promoter is highly active in cancer cells but not in normal cells. We therefore set out to assess whether we could confer this tumor-selectivity to an adenovirus vector. METHODOLOGY/PRINCIPAL FINDINGS Expression of an adenovirally-vectored luciferase reporter gene from the Rad51 promoter was up to 50 fold higher in cancer cells than in normal cells. Further ev...
