Effects of TO901317 on mRNA levels of ABCA1, apoA1, apoM, LRH-1 and SHP1 in Caco-2 cells. Caco-2 cells were cultured with different concentrations of TO901317 for 24 hrs. The mRNA levels of ABCA1, apoA1, apoM, LRH-1 and SHP1 were determined by real-time RT-PCR in triplicates. The controls were represented as 100%. Data represents one of two similar experiments (means ± SE, n = 5). *p < 0.05; **p < 0.01; ***p < 0.001 vs. controls.
