ABSTRACT
PURPOSE:
To elucidate the underlying mechanism of HIF-1α in migration and invasion of choriocarcinoma.METHODS:
Cell proliferation was determined by CCK-8 assay when cell invasion was detected by transwell assay. The protein expression was detected by western blotting, immunohistochemistry, and qPCR assay.RESULT:
HIF-1α was shown to be strongly expressed in both clinical tumour tissues and cell lines in choriocarcinoma. When HIF-1α was efficiently knocked down in JEG3 cells, the proliferation rate was reduced by approximately 50% and the number of cells that migrated through the transwell insert was greatly decreased. The cell invasion rate was also significantly reduced. Moreover, typical markers of epithelial-mesenchymal transition such as E-cadherin, were increased, while vimentin and α-SMA were decreased after HIF-1α knockdown. In contrast, overexpression of DEC1 reversed the effects of HIF-1α knockdown. Cell proliferation, migration, and invasion were partially recovered. The level of E-cadherin was decreased, while the level of vimentin and α-SMA was increased. In addition, the level of ß-catenin and LEF1 was downregulated after HIF-1α knockdown. The expression of MMP2 and MMP9 also declined. However, overexpression of DEC1 after HIF-1α knockdown partially reversed the expression pattern of these molecules.CONCLUSION:
HIF-1α contributed to EMT and metastasis through activation of canonical ß-catenin signalling in choriocarcinoma and this process was dependent on DEC1. This study provides a new mechanism of HIF-1α in choriocarcinoma and suggests that intervention with DEC1 might be a promising therapeutic choice for choriocarcinoma.Palabras clave
