This project focuses on the construction of an adenoviral vector to induce gene expression of enhanced green fluorescent protein or herpes simplex virus thymidine kinase (HSV-TK) upon irradiation of tumour cells. Following irradiation with clinically relevant doses of 2-6 Gy a significant induction of gene expression could be detected; furthermore, an enhanced cytotoxic effect could be shown after concomitant administration of HSV-TK and ganciclovir together with irradiation, compared to irradiation alone. The application of the employed promoter/ enhancer region of mEgr-1 is limited by a basal gene expression rate occurring without irradiation. Reduction of this basal promoter activity was achieved by flanking the expression cassette with polyadenylation sites deriving from bovine growth hormone.
