In this study, we demonstrated additional contributions of inflammation to the progression of lung cancer metastasis and a novel molecular target of EGCG, human neutrophil elastase, which induces lung cancer cell migration. 14 demonstrated that the natural polyphenol product curcumin inhibits tumor proliferation induced by neutrophil elastase via the upregulation of AAT in lung cancer. These results indicated that treatment with EGCG at a concentration between 10 and 20 μ M induces a substantial anti-migratory effect without affecting the proliferation of A549 cells exposed to neutrophil elastase. Our results showed that the neutrophil elastase-induced decrease in IRS-1 expression was significantly inhibited by EGCG in A549 cells. ./cache/cord-001712-a1sbdhhn.txt ./txt/cord-001712-a1sbdhhn.txt
