Effects of TAK-475, T-91485 and atorvastatin on apoAI-mediated (a) and HDL-mediated (b) cholesterol efflux from cholesterol-enriched THP-1 differentiated macrophages. Data are represented as mean±s.e.m percentage values of control (n=3). *P<0.025 and †P<0.05 vs control values (apoAI, 41,900±2254 dpm per milligram cell protein; HDL, 133,340±7362 dpm per milligram cell protein) by one-tailed Williams' test and Dunnett's test, respectively.
