Nymphaeol-A Isolated from Okinawan Propolis Suppresses Angiogenesis and Induces Caspase-Dependent Apoptosis via Inactivation of Survival Signals
Figure 10
Angiotensin II reverses inactivation of ERK1/2 by nymphaeol-A. HUVECs were pretreated with 1 μM angiotensin II, an ERK1/2 activator, for 3 h. Pretreated cells were incubated with nymphaeol-A at the indicated concentrations for 3 h. Caspase-3/7 activity was measured using the Caspase-Glo Assay Kit by luminescence assays as described in the text. *, as compared with the control group.
