HEK 293T cells were transfected with constructs directing the expression of G11αQ209L (0.5 μg/plate) or GqαQ209L (0.5 μg/plate) in the presence of CREB-β-galactosidase (0.5 μg/plate), SRE-luciferase (0.5 μg/plate), or pFR-luciferase (0.1 μg/plate) plus pFA2-Elk-1 (0.5 μg/plate). Transfection efficiency was normalized using a cytomegalovirus-β-galactosidase or cytomegalovirus-luciferase control vector. The amount of luciferase or β-galactosidase activity was measured 1 day later. Data are reported as the fold activation ± 2 S.D. of three experiments performed in duplicate compared to the activity of the reporter genes in the absence of activator.
