Angiogenesis is a crucial step in the growth and metastasis of cancers. Antiangiogenic activity of nomilin was studied using in vivo as well as in vitro models. Nomilin significantly inhibited tumor directed capillary formation. Serum proinflammatory cytokines such as IL-1 beta, IL-6, TNF-alpha and GM-CSF and also serum NO levels were significantly reduced by the treatment of nomilin. Administration of nomilin significantly reduced the serum level of VEGF. a proangiogenic factor and increased the antiangiogenic factors IL-2 and TIMP-1. In vitro studies using rat aortic ring assay showed that administration of nomilin at non-toxic concentrations significantly inhibited microvessel sprouting. Studies using human umbilical vein endothelial cells clearly demonstrated that administration of nomilin significantly retarded endothelial cell proliferation, migration, invasion and tube formation. These data clearly demonstrate the antiangiogenic potential of nomilin by downregulating the activation of MMPs, production of VEGF, NO and proinflammatory cytokines as well as upregulating IL-2 and TIMP.
