Development of methods to monitor cellular activity with magnetic resonance imaging (MRI) provides a powerful tool for studying disease progression and monitoring therapy. This thesis investigates components necessary for development of reporter gene expression for MRI, to track Nkx2.5 transcription factor activity during tumour growth and, in the future, to calibrate MR contrast against a well-known optical reporter gene, like firefly luciferase. In human MCF-7 breast cancer cells, Nkx2.5 is induced by all-trans retinoic acid (tRA) and activates a minimal promoter of the rat sodium iodide symporter (rNISmin) gene. Here, we used firefly luciferase reporter gene expression to examine a …
