QRT-PCR for 27-hydroxylase and ABCA1 message in indomethacin-treated THP-1 cells. (a) 27-Hydroxylase mRNA expression is decreased by the non-specific COX inhibitor indomethacin in a dose-dependent fashion in THP-1 monocytes. Cultured THP-1 monocytic cells were untreated or exposed to increasing doses of indomethacin for 18 hours. After isolation of total RNA, the RNA was reverse-transcribed and the cDNA amplified by QRT-PCR as described. Signals obtained from the amplification of GAPDH message were used as internal controls. (b) ABCA1 mRNA expression is decreased by the non-specific COX inhibitor indomethacin in a dose-dependent fashion in THP-1 monocytes. Cultured THP-1 monocytic cells were untreated or exposed to increasing doses of indomethacin for 18 hours. After isolation of total RNA, the RNA was reverse-transcribed and the cDNA amplified by QRT-PCR as described. Signals obtained from the amplification of GAPDH message were used as internal controls. At 50 mM indomethacin concentration, cell death was statistically significant (16.8% ± 1.0%). ABCA1, ATP-binding cassette transporter A1; COX, cyclooxygenase; GAPDH, glyceraldehyde-3-phosphate dehydrogenase; QRT-PCR, quantitative real-time polymerase chain reaction. * p < 0.05, ** p < 0.01.
