Fasentin diminishes endothelial cell proliferation, differentiation and invasion in a glucose metabolism-independent manner. Sci Rep. 2020 Apr 9;10(1):6132http://hdl.handle.net/10668/4149The synthetic compound fasentin has been described as a modulator of GLUT-1 and GLUT-4 transporters, thus inhibiting glucose uptake in some cancer cells. Endothelial glucose metabolism has been recently connected to angiogenesis and it is now an emerging topic in scientific research. Indeed, certain compounds with a known effect on glucose metabolism have also been shown to inhibit angiogenesis. In this work we tested the capability of fasentin to modulate angiogenesis in vitro and in vivo. We show that fasentin inhibited tube formation in endothelial cells by a mechanism that involves a negative effect on endothelial cell proliferation and invasion, without affecting other steps related to the angiogenic process. However, fasentin barely decreased glucose uptake in human dermal microvascular endothelial cells and the GLUT-1 inhibitor STF-31 failed to inhibit tube formation in these cells. Therefore, this modulatory capacity on endothelial cells function exerted by fasentin is most likely independent of a modulation of glucose metabolism. Taken together, our results show a novel biological activity of fasentin, which could be evaluated for its utility in cancer and other angiogenesis-dependent diseases.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/AnilidesEndothelial cellsGlucoseCell proliferationAnilidasCélulas endotelialesGlucosaProliferación celularMedical Subject Headings::Chemicals and Drugs::Organic Chemicals::Amides::AnilidesMedical Subject Headings::Organisms::Eukaryota::AnimalsMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Artiodactyla::Ruminants::CattleMedical Subject Headings::Anatomy::Cells::Cells, CulturedMedical Subject Headings::Anatomy::Animal Structures::Embryo, Nonmammalian::Chick EmbryoMedical Subject Headings::Chemicals and Drugs::Carbohydrates::Monosaccharides::Hexoses::GlucoseMedical Subject Headings::Anatomy::Cells::Cells, Cultured::Cell Line::Cell Line, Tumor::HeLa CellsMedical Subject Headings::Anatomy::Cells::Epithelial Cells::Endothelial Cells::Human Umbilical Vein Endothelial CellsMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Anatomy::Cells::Cells, Cultured::Cell Line::Cell Line, Tumor::MCF-7 CellsMedical Subject Headings::Phenomena and Processes::Circulatory and Respiratory Physiological Phenomena::Cardiovascular Physiological Phenomena::Cardiovascular Physiological Processes::Neovascularization, PhysiologicMedical Subject Headings::Chemicals and Drugs::Heterocyclic Compounds::Heterocyclic Compounds, 1-Ring::PyridinesMedical Subject Headings::Phenomena and Processes::Cell Physiological Phenomena::Cell Physiological Processes::Cell DifferentiationMedical Subject Headings::Phenomena and Processes::Cell Physiological Phenomena::Cell Physiological Processes::Cell MovementMedical Subject Headings::Phenomena and Processes::Physiological Phenomena::Physiological Processes::Growth and Development::Growth::Cell Growth Processes::Cell Proliferationresearch article32273578Acceso abierto10.1038/s41598-020-63232-z2045-2322PMC7145862
