Object
The goal of this study was to evaluate gene delivery to a benign brain tumor.
Methods
A recombinant adenovirus vector bearing the Escherichia coli ß-galactosidase reporter gene was selectively injected into the vascular supply of a spontaneously occurring canine olfactory groove meningioma. The tumor and a small amount of peritumoral brain tissue were removed 5 days after viral injection and stained with X-Gal to assess gene delivery. The authors noted significant ß-galactosidase gene expression by the tumor, but not by surrounding brain tissue. No obvious viral-related cytotoxicity was noted.
Conclusions
The authors found that meningiomas can be successfully transduced by adenovirus vectors by using endovascular techniques.
