Figure 6. qPCR analysis of mRNA expression after suberoylanilide hydroxamic acid (SAHA) treatment in lipopolysaccharide (LPS)-challenged BEAS-2B cells and in A549 cells.
(A) The expression level of IL-1 and IL-6 in BEAS-2B cells; (B) The expression level of DNMT1 and DNMT3A in BEAS-2B cells; C) The expression level of DNMT1 and DNMT3A in A549 cells. *P < 0.05, **P < 0.01, and ***P < 0.001 indicate statistically significant. All experiments were conducted in triplicate (n = 3).
