Abstract

Boehmeria nivea (L.) Gaud., a flowering plant, has been widely cultivated in Asian countries including Korea. It has been reported that B. nivea exhibits health beneficial effects for the prevention of inflammation, oxidative stress, and virus-related diseases. In this study, we evaluated the inhibitory effect of B. nivea on adipocyte differentiation and angiogenesis. DPPH radical scavenging activities of 70% ethanol extract of B. nivea (EBN) and water extract of B. nivea (WBN) were $90.8{\pm}1.1%$ and $20{\pm}6.9%$, respectively. EBN was also effective in the reduction of adipocyte differentiation in 3T3-L1 cells. We next examined the transcriptional activity of peroxisome proliferator-activated receptor gamma ($PPAR-{\gamma}$), a pivotal target for anti-obesity. We found that treatment with rosiglitazone induced the transactivation of $PPAR-{\gamma}$. Under the same condition, $800{\mu}g/mL$ EBN reduced the transactivation of $PPAR-{\gamma}$ in rosiglitazone-induced cells. These results demonstrate that EBN-inhibited adipocyte differentiation was accompanied by $PPAR-{\gamma}$ inhibition. The study also tested whether EBN exhibits an anti-angiogenic effect by inhibiting tube formation in HUVECs. We found that EBN effectively inhibits tube formation, suggesting that EBN exhibited an anti-angiogenic effect. Taken together, B. nivea can be used as a functional food for the prevention of obesity and angiogenesis-related diseases including cancer.
