Abstract
PURPOSE:Glioblastoma (GBM) remains one of the most fatal malignancy with limited available treatment. Serpin peptidase inhibitor, clade E nexin group 1 (SERPINE1) was found up-regulated in multiple cancers and play crucial roles in facilitating tumor progression and metastasis respectively. However, the role of SERPINE1 in glioblastoma was poorly understood.METHODS:We tested the hypothesis that SERPINE1 mediated malignant behaviors in GBM via regulating hairy and enhancer of split-1 (HES1).RESULTS:First, SERPINE1 is confirmed to be up-regulated in GBM, while further functional analysis demonstrated that SERPINE1 promoted cell proliferation, migration and invasion in GBM by performing the CCK-8 assay, colony formation assay, wound healing assay and transwell assay. Finally, it was proved that SERPINE1 achieved its pro-tumor functions in GBM via regulating the expression of HES1.CONCLUSIONS:Collectively, our results highlight the critical contribution of SERPINE1 in a series of malignant characteristics of GBM via regulating the expression of HES1, which shed new light on a new direction to develop a more effective therapeutic management of malignant tumors like GBM.
