*AREDS, AREDS antioxidants (Antiox.) and rosemary were solubilized with vehicle (1% Tween 80/16% ethanol/ 25% ROPUFA). Zinc oxide and copper oxide levels per AREDS1 formula [6]. Zinc oxide was dissolved in distilled water [25]. Carnosic acid and ursolic acid were solubilized with 50% pure ethanol/ 50% ROPUFA. Weanling male Sprague-Dawley rats were supplemented for 6 weeks before intense light exposure or sacrifice for gene array analysis. Short-term supplementation was for 1 week prior to intense light treatment and subsequent analysis. The numbers in parenthesis indicate the n for each sub-group of dietary treatment. Comparable numbers of vehicle and AREDS fed rats were used for these experiments.
