Liver gene expression in apoE^−/− mice fed chow or vitamin A-deficient diet with or without β-carotene. Liver mRNA levels of the indicated genes were detected by real-time PCR. Gapdh was used as a reference gene. Gene expression was detected after 15 weeks of treatment. Cyp26a1 (a), Pparγ (b), Cyp7α(c), and Hmgr (d). Measured by real-time PCR and normalized to GAPDH. Values are means ± SE, n = 8. ^{a, b, c}Within each graph, means without a common letter differ, P < 0.05. Dunaliella treated group (BC); vitamin A-deficient diet group (VAD); vitamin A-deficient diet fortified with Dunaliella group (VAD-BC).
