Figure 1. Chemical structure of zerumbone and experimental protocol for dietary zerumbone supplementation after UVB irradiation to the mouse cornea. A: The chemical structure of zerumbone. B: Daily UVB light exposure (indicated by arrows) was performed from Day 1 to Day7, with dietary zerumbone given at 1, 10, and 100 mg/kg of bodyweight, respectively, from Day 0 until Day 8. No zerumbone was given to the UVB group or the blank control group.
