Research Abstract

Blood vessels are therapeutic targets for cancer, ischemic diseases and diabetes-related diseases. Therefore, understanding the process of angiogenesis is important for not only intellectual but potentially development of medicine for such diseases. A novel Rho-related gene, RhoJ was investigated for its physiological function by knocking out. The RhoJ KO exhibited retarded angiogenesis in the retina. Since the retina showed empty sleeves, regression seems to be one of causes for the retarded angiogenesis.
Flk1-GFP :: Flt1-tdsRed BAC Tg mice were created to monitor the endogenous expression of Flk1 and Flt1. Based on the expression of Flk1-GFP and Flt1-tdsRed, Flk1 and Flt1 are expressed in micro capillaries and mid/major endothelial cells, respectively.
