Percentage apoptosis as determined by caspase 3 assay and flow cytometric analysis. Cells were treated with 3 different concentrations of dexamethasone for 48 hours (top panel) and 60 hours (middle panel). The experiment was performed twice with similar results. (Bottom panel) Table describing the properties of transactivation, transrepression, and RAFTK phosphorylation for the cells expressing GR mutants.
