Alpha-mangostin suppresses phorbol 12-myristate 13-acetate-induced MMP-2/MMP-9 expressions via alphavbeta3 integrin/FAK/ERK and NF-kappaB signaling pathway in human lung adenocarcinoma A549 cells.

The purpose of this study is to investigate the anti-metastatic effect of alpha-mangostin on phorbol 12-myristate 13-acetate (PMA)-induced matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) expressions in A549 human lung adenocarcinoma cells. Firstly, alpha-mangostin could inhibit PMA-induced abilities of the adhesion, invasion, and migration. Data also showed alpha-mangostin could inhibit the activation of alphavbeta3 integrin, focal adhesion kinase (FAK), and extracellular signal-regulated kinase1/2 (ERK1/2) involved in the downregulation the enzyme activities, protein and messenger RNA levels of MMP-2 and MMP-9 induced by PMA.
