Abstract
The Camella japonica flower(CJF) extract was studied for their anti-angiogenenic and anti-cell adhesion effect. CJF-extract inhibited the tube formation on human umbilical vein endotherial cells(HUVEC) with butanol extract by 70.2%, acetone extract by 54.2%, ethyl acetate extract by 37.0%, chloroform extract by 21.2%. Cell adhesion molecules were effectively suppressed at different concentration of CJF at 50, 100, 200 ug/well such as for intercellular adhesion molecule(ICAM) by 5.9%, 29.4% and 52.9%, for vascular cell adhesion molecule(VCAM) by 12.5%, 43.8% and 62.5%, for E-selectin by 7.1%, 21.4% and 35.7%, respectively. Signal molecules of vascular endotherial growth factor receptor 2(VEGFR2), ${/beta}$-catenin and PI3K are inhibited by different concentration of CJF at 10, 20 and 30 ${\mu}g/mL$ with western blot. Angiogenesis will be inhibited with suppressing NF-kB molecule resulted in signal molecules blocked by CJF. CJF will be useful materials for treatment of angiogenesis related diseases such as cancer, metastasis, rheumathioid arthritis and obesity.
