Figure 2: Matrine affects the LPS-induced productions of COX and ICAM-1 in A549 cells. COX-2 and ICAM-1 protein levels were detected using Western blots with β-actin expression as an internal control (a), and ICAM-1 levels were measured by ELISA (b). (c) Treatment with 100–400 μM matrine (M) inhibited the adherence of neutrophil-like HL-60 cells to active A549 cells. Data are presented as the mean ± SEM. compared to LPS alone.
