Effect of lutein and zeaxanthin supplementation on RPE/choroid A2E and iso-A2E levels in Abca4−/−/Bco2−/− and Abca4−/− mice. (a) Presents A2E levels, and (b) presents iso-A2E levels in Abca4−/−/Bco2−/− and Abca4−/− mice fed with the indicated carotenoids for three months. A placebo group supplemented carotenoid-free beadlets serves as the control. Data presented as mean ± SEM (n=12 mice/group, p values: **p<0.01, *p<0.05; N.D.: not detected).
