METHODS: Human U937 cells were stimulated by in- cubation with 100 nM phorbo112-myristate 13-ace- tate (PMA) for 48 h.These stimulated, monocyte-like cells were then incubated for 24 h with 50 mg/L oxi- dized low-density lipoprotein (ox-LDL, to induce foam cell formation), together with a liver X recep- tor (LXR) agonist or with different DHI concentra- tions. MSR1 and ABCA1 mRNA levels were mea- sured by fluorescence-based quantitative PCR. RESULTS: Compared with control cells (which re- ceived only ox-LDL), cells treated with both ox-LDL and 10 IJmol/L LXR agonist showed lower MSR1 ex-pression (but this effect was not statistically signifi- cant, P〉0.05) and higher ABCA1 expression (P〈 0.01). Cells that received ox-LDL and 3 mL/L DHI possessed higher MSR1 mRNA levels than the con- trols, whereas cells treated with ox-LDL and higher DHI concentrations (10, 30 or 60 mL/L) showed low- er MSR1 expression levels (but the differences ob- served between DHI concentration groups were not statistically significant, P〉0.05). ABCA1 expression in cells treated with ox-LDL and 3, 10 or 30 mL/L DHI was higher than in the control cells, and increased with increasing DHI concentration (P〈0.05). ABCA1 expression in cells treated with ox-LDL and the highest DHI concentration tested (60 mL/L) was not significantly different from that in the controls. ABCA1 mRNA levels in cells treated with ox-LDL and DHI were similar to, or lower than, those in cells treated with ox-LDL and the LXR agonist. CONCLUSION: DHI does not affect MSR1 mRNA lev- els in ox-LDL-treated U937 cells. However, at certain concentrations (10 and 30 m展开更多
