Abstract

Interleukin-8 (IL-8), an important inflammatory cytokine, is strongly associated with gastric cancer development and metastasis. High-dose (>1 ng/ml) IL-8 has been revealed to promote the adhesion, migration and invasion of human gastric cancer SGC-7901 cells in a dose-dependent manner. However, the IL-8 level produced by gastric cells is marginal, at even less than 1 ng/ml. It is unclear whether low-dose IL-8 also induces these capacities. In the present study, the effect of low-dose IL-8 on the adhesion, migration and invasion of the SGC-7901 cell line and the underlying molecular mechanism with regard to cluster of differentiation 44 (CD44) were investigated. The SGC-7901 cells were exposed to various concentrations of IL-8 (0, 0.2, 0.5, 0.8 and 1 ng/ml) . The adhesion of the SGC-7901 cells to fibronectin, an extracellular matrix component, was then detected by cell counting kit 8 assay. Migration and invasion abilities were evaluated by wound scratch and Transwell chamber assays. In addition, protein and mRNA levels of CD44 were measured using immunofluorescence and western blotting, and quantitative polymerase chain reaction, respectively, in cells cultured for 72 h. Following the exposure of the SGC-7901 cells to the various low doses of IL-8, the cell adhesion, migration and invasion capacities were promoted by IL-8, but not in a significant dose-dependent manner. Low-dose IL-8 upregulated the protein and mRNA expression of CD44. In conclusion, low-dose IL-8 potently induces the adhesion, migration and invasion of SGC-7901 cells, and the regulation of CD44 expression is one of the potential molecular mechanisms involved.
