When the wild-type hGR and hGR -Ile 729 were expressed in CV-1 cells that were cotransfected with the mouse mammary tumor virus long terminal repeat fused to the chloramphenicol acetyl transferase ( CAT ) gene , the hGR -Ile 729 conferred a fourfold decrease in apparent potency on dexamethasone stimulation of CAT activity .
