LEO increases the viability of LPS-stimulated BEAS-2B cells. (A) Chemical structure of LEO. BEAS-2B cell viability was quantified using (B) MTT and (C) CCK-8 assays following pretreatment with various concentrations of LEO and subsequent LPS stimulation. Data are presented as the mean ± standard deviation of three independent experiments. ***P<0.001 vs. control; #P<0.05, ###P<0.001 vs. LPS. CCK-8, Cell Counting Kit-8; LEO, leonurine; LPS, lipopolysaccharide.
