Effects of Dx on expression of atherosclerosis-associated CD molecules induced by 27OHChol. (a) After incubation with 27OHChol (2.5 μg/mL) for 48 h with or without 0.1, 1, or 10 μM of Dx, transcription of CD105, CD137, and CD166 was analyzed by real-time PCR. Data are expressed as mean ± SD ( replicates/group). versus control; versus 27OHChol. (b) THP-1 cells (1 × 106 cells/60 mm culture dish) were cultured for 48 h with 2.5 μg/mL of 27OHChol with or without 1 μM of Dx. The harvested cells were immunostained with antibodies against CD105, CD137, and CD166 and analyzed by flow cytometry. Results are representative of three independent experiments.
