Scutellarin suppresses triple-negative breast cancer metastasis by inhibiting TNFα-induced vascular endothelial barrier breakdown
文献摘要：
Triple-negative breast cancer(TNBC)is an aggressive subtype of breast cancer with high vascularity and frequent metastasis.Tumor-associated abnormal vasculature was reported to accelerate TNBC metastasis.Scutellarin(SC)is a natural flavonoid with a cardiovascular protective function.In this study,SC reduced TNBC metastasis and alleviated tumor-associated vascular endothelial barrier injury in vivo.SC rescued the tumor necrosis factor-α(TNFα)-induced diminishment of endothelial junctional proteins and dysfunction of the endothelial barrier in vitro.SC reduced the increased transendothelial migration of TNBC cells through a monolayer composed of TNFα-stimulated human mammary microvascular endothelial cells(HMMECs)or human umbilical vein endothelial cells(HUVECs).TNFα induced the nuclear translocation of enhancer of zeste homolog-2(EZH2),and its chemical inhibitor GSK126 blocked TNFα-induced endothelial barrier disruption and subsequent TNBC transendothelial migration.TNF receptor 2(TNFR2)is the main receptor by which TNFα regulates endothelial barrier breakdown.Extracellular signal-regulated protein kinase(ERK)1/2 was found to be downstream of TNFα/TNFR2 and upstream of EZH2.Additionally,SC abrogated the TNFR2-ERK1/2-EZH2 signaling axis both in vivo and in vitro.Our results suggest that SC reduced TNBC metastasis by suppressing TNFα-initiated vascular endothelial barrier breakdown through rescuing the reduced expression of junctional proteins by regulating the TNFR2-ERK1/2-EZH2 signaling pathway.
