Apoastaxanthinals suppressed the mRNA expression of inflammatory factors in the activated RAW264.7 macrophages. Carotenoid-pretreated (5 μM for 2 h) cells are stimulated by LPS (100 ng/mL for 6 h) in the presence of carotenoids (5 μM). The levels of each inflammatory factor mRNA expression were determined by the quantitative PCR method. Gapdh was used as the endogenous control. Data are represented as the mean ± SEM (n = 3) with different letters (p < 0.05). Apo11: apo-11-astaxanthinal. Apo14′: apo-14′-astaxanthinal. Apo12′: apo-12′-astaxanthinal. Apo10′: apo-10′-astaxanthinal. Apo8′: apo-8′-astaxanthinal.
