Zusammenfassung: | The recruitment of bone marrow-derived endothelial progenitor cells (EPCs) facilitates physiological and pathological processes involved in new blood vessel synthesis. Glucocerebroside, an extract of Cordyceps militaris, inhibits inflammatory cytokine production and monocyte migration, although its anti-angiogenic properties in human EPCs has remained largely unknown up until now. We describe how glucocerebroside reduces migration as well as tube formation induced by vascular endothelial growth factor (VEGF) stimulation in human EPCs, without affecting cell viability. This inhibitory effect was achieved through the focal adhesion kinase (FAK)/c-Src pathways. We also found that glucocerebroside reduced VEGF-promoted upregulation of the transcription factor Runx2 in the EPCs. The in vivo chick embryo chorioallantoic membrane model demonstrated that glucocerebroside reduces new vessel formation. Our investigation is the first to show that glucocerebroside reduces angiogenesis in human EPCs and to describe the underlying mechanisms. Further investigations are needed to examine the effects of glucocerebroside in other angiogenesis-related disorders. |
