タイトル Overexpression of the nucleoporin Nup88 stimulates migration and invasion of HeLa cells.
ジャーナル Histochem Cell Biol
Abstract Elevated expression of the nucleoporin Nup88, a constituent of the nuclear pore complex, is seen in various types of malignant tumors, but whether this overexpression contributes to the malignant phenotype has yet to be determined. Here, we investigated the effect of the overexpression of Nup88 on the migration and invasion of cervical cancer HeLa cells. The overexpression of Nup88 promoted a slight but significant increase in both migration and invasion, whereas knockdown of Nup88 by RNA interference suppressed these phenotypes. The observed phenotypes in Nup88-overexpressing HeLa cells were not due to the progression of the epithelial-to-mesenchymal transition or activation of NF-κB, which are known to be important for cell migration and invasion. Instead, we identified an upregulation of matrix metalloproteinase-12 (MMP-12) at both the gene and protein levels in Nup88-overexpressing HeLa cells. Upregulation of MMP-12 protein by the overexpression of Nup88 was also observed in one other cervical cancer cell line and two prostate cancer cell lines but not 293 cells. Treatment with a selective inhibitor against MMP-12 enzymatic activity significantly suppressed the invasive ability of HeLa cells induced by Nup88 overexpression. Taken together, our results suggest that overexpression of Nup88 can stimulate malignant phenotypes including invasive ability, which is promoted by MMP-12 expression.
