Effects of Trichosanthes kirilowii Extract against Angiogenesis and Various Tumor Cells' Growth

천화분 추출물이 혈관신생 및 암세포성장에 미치는 영향

Objectives : This study was aimed to elucidate the effects of Trichosanthes kirilowii extract (TKE) on the angiogenesis and growth of tumor cells. Methods : Tube formation assay was performed by using human umbilical vein endothelial cells (HUVEC), and anchorage dependent colony assay was performed by using B16-F10 melanoma, Hep G2 and HT1080, CT-26 and SNU-1 cells. Results : For HUVEC, TKE at a level of more than 100 ${\mu}g/m{\ell}$ suppresses cell growth. For HUVEC at 100 ${\mu}g/m{\ell}$ and greater TKE density, the formation of tubes was suppressed in a dose-dependant manner. TKE controls the colony formations of B16-F10 melanoma cells, CT 26 cells, and Hep G2 cells, and its effect is proportional to density. In HT1080 cells and SNU-1 cells, formation is suppressed regardless of density. Conclusions : From these results, it could be concluded that TKE has significant properties on anti-angiogenesis and growth inhibiting of tumor cells. It is suggested that TKE will be a good candidate for new drugs or therapeutics for anti-angiogenesis.
