1 Organ-specific activation of activator protein-1 in transgenic mice by 12-o-tetradecanoylphorbol-13-acetate with different administration methods. Tetradecanoylphorbol Acetate jun proto-oncogene Mus musculus
2 injection), we analyzed TPA-stimulated activator protein-1 (AP-1) activity in various organs (liver, kidney, brain, lung, spleen, heart, stomach, colon, esophagus, and skin) from transgenic mice expressing the AP-1 luciferase reporter gene. Tetradecanoylphorbol Acetate jun proto-oncogene Mus musculus
