Angiogenesis
Research in the area of angiogenesis reported from RIKEN
March 17th, 2009
"Shikonin and beta-hydroxyisovalerylshikonin (beta-HIVS) from Lithospermum erythrorhizon inhibit angiogenesis via inhibition of vascular endothelial growth factor receptors (VEGFR) in an adenosine triphosphate-non-competitive manner, although the underlying molecular mechanism has not been fully understood. In the present study, we found that beta-HIVS inhibited angiogenesis within chicken chorioallantoic membrane approximately threefold more efficiently than shikonin. beta-HIVS also significantly inhibited angiogenesis in two other assays, induced either by Lewis lung carcinoma cells implanted in mouse dorsal skin or by VEGF in s.c. implanted Matrigel plugs and metastasis of Lewis lung...
