Isolinderalactone suppresses human glioblastoma growth and angiogenic activity in 3D microfluidic chip and in vivo mouse models
Cancer Lett
Glioblastoma multiforme (GBM) is a lethal and highly vascular type of brain tumor. We previously reported that isolinderalactone enhances GBM apoptosis in vitro and in vivo, but its role in tumor angiogenesis is unknown.

- Paper Abstract
- Glioblastoma multiforme (GBM) is a lethal and highly vascular type of brain tumor. We previously reported that isolinderalactone enhances GBM apoptosis in vitro and in vivo, but its role in tumor angiogenesis is unknown. Here, we investigated the anti-angiogenic activity of isolinderalactone and its mechanisms. In a human GBM xenograft mouse model, isolinderalactone significantly reduced tumor growth and vessels. Isolinderalactone decreased the expression of vascular endothelial growth factor (VEGF) mRNA, protein, and VEGF secretion in hypoxic U-87 GBM cells and also in xenograft GMB tissue. In addition, we demonstrated that isolinderalactone significantly inhibited the proliferation, migration, and capillary-like tube formation of human brain microvascular endothelial cells (HBMECs) in the presence of VEGF. We also found that isolinderalactone decreased sprout diameter and length in a 3D microfluidic chip, and strongly reduced VEGF-triggered angiogenesis in vivo Matrigel plug assay. Isolinderalactone downregulated hypoxia-inducible factor-1alpha (HIF-1alpha) and HIF-2alpha proteins, decreased luciferase activity driven by the VEGF promoter in U-87 cells under hypoxic conditions, and suppressed VEGF-driven phosphorylation of VEGFR2 in HBMECs. Taken together, our results suggest that isolinderalactone is a promising candidate for GBM treatment through tumor angiogenesis inhibition.
