Fig. 2. Bmal1-Luc cell luminescence intensities with cortisol addition.

a Successive changes of luminescence intensities of Bmal1-Luc cells by adding 1 nM, 10 nM, 25 nM, 75 nM, and 100 nM cortisol to the medium. One representative of two experiments with similar results is shown. b Successive changes of relative luminescence intensities of Bmal1-Luc cells by administrating 25 nM cortisol and glucocorticoid receptor inhibitor (GRi) at 40 h and 52 h after serum shock (Blue arrows). One representative of two experiments with similar results is shown.
