Effect of APOA1 on basal tocopherol secretion in control and LXR-induced Caco-2 monolayers. Monolayers were treated with T0901317, BMS201038, and mixed micelles as in Fig. 1 and 2. APOA1 (0, 6, 12, or 20 μg/mL media) was added to the basolateral compartment and basal tocopherol (A) and unesterified cholesterol (C) secretion were determined after 24 h. (B) Secretion efficiency. Results are expressed as means ± SDs (A and B, n = 9; C, n = 3). *P < 0.001 vs. 0 μg/mL; x, P < 0.02 vs. 0 μg/mL; linear fits without a common letter differ: a, d, P < 0.001. APOA1, apolipoprotein A1; T, T0901317; TOH, tocopherol.
