FIG. 1.

Effects of Lippia extract on activation of cAMP response element (CRE)-responsive luciferase reporter. HEK293T cells expressing a CRE-responsive luciferase reporter were treated with increasing concentrations (1.6–100 μg/mL) of Lippia extract for 4 h. Results are plotted as relative luminescence units (RLUs) against increasing concentrations of Lippia extract (EC₅₀=20 μg/mL). Results are representative of three separate experiments and data reported as mean±one standard deviation (SD).
