Interleukin 17A Promotes Gastric Cancer Invasiveness via NF-κB Mediated Matrix Metalloproteinases 2 and 9 Expression
Interleukin 17A (IL-17A), as a pro-inflammatory cytokine, is involved in pathology of inflammatory diseases and tumor microenvironment. The aim of this study is to investigate the effect of IL-17A on the invasiveness of gastric cancer (GC). In the study, we found that IL-17A could promote the migrat...

description | Interleukin 17A (IL-17A), as a pro-inflammatory cytokine, is involved in pathology of inflammatory diseases and tumor microenvironment. The aim of this study is to investigate the effect of IL-17A on the invasiveness of gastric cancer (GC). In the study, we found that IL-17A could promote the migration and invasion of GC cells. Furthermore, after treated with IL-17A, the expressions and activities of matrix metalloproteinase 2 (MMP-2) and MMP-9 were upregulated, while the expressions of TIMP-1 and TIMP-2 were downregulated. Moreover, the nuclear/overall fractions of p65 and p50 were dramatically elevated by IL-17A. Pretreatment with helenalin, a nuclear factor-κB (NF-κB) inhibitor, was proved to abolish the promoting effect of IL-17A on the invasion ability of GC cells and upregulation of MMP-2 and MMP-9. In conclusion, our findings illustrated that IL-17A could promote the invasion of GC cells by activating NF-κB pathway, and subsequently upregulating the expression of MMP-2 and MMP-9. These results may lead to the identification of new diagnostic markers and therapeutic targets of GC. |
