Abstract

The effect of indole-3-carbinol (I3C), a major indolic metabolite in cruciferous vegetables, on lipopolysaccharide (LPS)-activated macrophage-induced tube formation and its associated factors in endothelial EA hy926 cells was investigated. LPS significantly enhanced the capillary-like structure of endothelial cells (ECs) co-cultured with macrophages, but no such effect was observed in single-cultured ECs. I3C, on the other hand, suppressed such enhancement in concert with decreased secretions of vascular endothelial growth factor (VEGF), nitric oxide (NO), interleukin-6 (IL-6), and matrix metalloproteinases (MMPs). The results obtained from cultivating ECs with conditioned medium (CM) collected from macrophages suggested that both ECs and macrophages were inactivated by I3C. These results indicate that I3C from cruciferous vegetables may possess potential roles in preventing inflammation-associated angiogenic diseases.
