We proposed to exploit hypoxia-inducible factor (HIF)-1alpha overexpression in prostate tumours and use this transcriptional machinery to control the expression of the suicide gene cytosine deaminase (CD) through binding of HIF-1alpha to arrangements of hypoxia response elements. CD is a prodrug activation enzyme, which converts inactive 5-fluorocytosine to active 5-fluorouracil (5-FU), allowing selective killing of vector containing cells.

Image-Guided Targeting in Preclinical Studies: Tumors and Normal Tissues
While SARRP is often used to investigate the effect of radiation therapy in preclinical oncology settings, it should be noted that the impact of radiation on normal tissues requires understanding and further research to mitigate both early and late effects. The use of...
