Abstract

Angiogenesis has essential role in growth and metastasis of tumors. Development of therapies aimed to suppress Angiogenesis using medicinal plants is one of the effective approaches for prevention/treatment of cancer. The current study was performed to investigate in vitro anti-angiogenic effect of Teucrium Polium (TP) extract and its fractions. The aerial part of Teucrium Polium was powdered and extracted with 50% ethanol. The extract was fractionated in to aqueous (AQ), n-butanol (BU), ethyl acetate (EA) and nhexane (HE) fractions. Anti-angiogenic effect of TP was examined on human umbilical vein endothelial cells (HUVECs) in three-dimensional collagen matrix. The endothelial cells form capillary-like branches that can be visualized using phase contrast microscope and the number of tube-like structures can be quantified as a measure of in vitro Angiogenesis. Furthermore, anti-proliferative and Vascular endothelial growth factor(VEGF )suppressive effect of TP as important factors in the process of Angiogenesis were assessed using3-(4, 5-dimethyl-thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT)and quantitative ELISA, respectively. Based on our findings, among the TP fractions, EA fraction showed the highest inhibitory activity on Angiogenesis. This fraction with IC50: 68 μ g/mL, inhibited Angiogenesis at 60 μ g/mL. The crude extract and other fractions of TP inhibited Angiogenesis in a dose-dependent manner at doses higher concentrations than EA fraction, significantly. TP extract and EA fraction were able to inhibit Proliferation of HUVEC and inhibited VEGF secretion in a dose dependent manner. The ethyl acetate fraction at 60 μ g/ml inhibited VEGF secretion perfectly. Our data indicated that ethyl acetate fraction of Teucrium Polium could be a potential candidate for the prevention of Angiogenesis in cancer and other related disorders. However, this suggestion needs more quantitative and in vivo investigations for confirmation.
