Fig. 4. Inhibition of PM10-induced TNF-α by LL-EA and oleanolic acid in keratinocytes. (A) HaCaT was pre-treated with different concentrations of LL-EA (2.5, 5, 10 μg/mL) or oleanolic acid (2.5, 5, 10 μg/mL) for 6 h, and after that PM10 (50 μg/mL) was treated for 18 h and analyzed by RT-PCR. Histograms of quantitated mRNA expression were showed in (B).
