LPA induced the expression, secretion and activity of MMP-9 in a dose- and time- dependent manner. Macrophages were treated with the pointed concentrations of LPA for 24 h or with 10 μM LPA for the pointed time course. The mRNA levels (A,E), protein levels (B,F), secretion (C,G) and activity (D) of MMP-9 were detected by RT-PCR, Western Blot, ELISA and gelatin zymography, respectively. LPA induced MMP-9 expression in human peripheral blood monocyte-derived macrophages (H). Data were expressed as mean ± SD of three independent experiments. *P < 0.05, compared with control.
