Inhibition of angiogenesis and metastasis of uveal melanoma cells by astragaloside IV
Astragaloside IV (AS) has been recently shown to possess pharmacologic activities against cancer. Vascular endothelial growth factor (VEGF) plays a prominent role in the induction of physiological or pathophysiological processes of tumor angiogenesis. The present study focuses on the anti-angiogenesis effects of AS in uveal melanoma cells. In this study, AS was demonstrated to exhibit higher anti-proliferation activity...

Analysis of anti-oxidant activity of medicinal plants according to the extracted parts
In this research, we compared and analyzed the anti-oxidant activity of ten medicinal plants using an oriental medicine and a folk remedy. Among them, the extracts from Oenothera odorata had the highest anti-oxidant effect. The extracts from the root, stem and flower ofO. odorata were tested by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity test, 3-[4, 5-dimethylthiazol-2-yl]-2,...

In vitro anti-angiogenic activity fractions from hydroalcoholic extract of Elaeagnus angustifolia L. flower and Nepeta crispa L. arial part
Angiogenesis is an essential event in the tumor growth and Metastasis. The aim of our research is to study the effect of Elaeagnus angustifolia and Nepeta crispa extracts on anti-angiogenic activities in human umbilical endothelial cells (HUVEC). Hydroalcoholic extract and its successive hexane, ethyl acetate, chloroform and aqueous fractions were used in different concentration by three...

Glycyrrhizin and isoliquiritigenin production by hairy root culture of Glycyrrhiza glabra
Glycyrrhizin and isoliquiritigenin production by hairy root culture of Licorice (Glycyrrhiza glabra) was investigated using Agrobacterium rhizogenes strain AR15834. Hairy roots were induced by inoculation of the leaf and stem explants with A. rhizogenes. Presence of therolB gene in the hairy root lines was performed by polymerase chain reaction (PCR) and using rolB gene specific primers....
