TPA induces MMP-13 and MMP-3 in skin. a, TPA (10 nmol) in acetone was applied to the back skin. After 0, 1, 4, and 6 h, mice were killed and RNA from skin was prepared. MMP-13, MMP-3, c-jun, and c-fos expression was analyzed by Northern blot analysis. b, TPA (0.1, 1, 10, and 50 nmol) was applied as described in a, and animals were killed after 6 h and analyzed by Northern blot analysis. Rehybridization with a cDNA fragment of 18 S RNA was performed serving as a loading control.
