Abstract
A DNA sequence for the gene therapy of tumors is described. In its essential elements, the DNA sequence is composed of an activator sequence, a promoter module and a gene for the active substance. The activator sequence is activated, in a cell-specific manner, in proliferating endothelial cells or in cells which are adjacent to these endothelial cells. This activation is regulated by the promoter module in a cell cycle-specific manner. The active substance is an inhibitor of angiogenesis or a cytostatic or cytotoxic molecule. The DNA sequence is inserted into a viral or non-viral vector which is supplemented with a ligand which possesses affinity for the activated endothelial cell.
Claims52
A DNA construct for the prophylaxis or therapy of tumor diseases, which comprises an activator sequence, a cell cycle-regulated promoter module, and a DNA sequence encoding an antitumor substance, wherein said promoter module comprises a cell cycle dependent element, a cell cycle homology region, and an initiation site.
