| Outline of Final Research Achievements |
A disintegrin and metalloprotease with thrombospondin type I motifs 1 (ADAMTS1), a member of the matrix metalloproteinase family, inhibits angiogenesis and lymphangiogenesis. ADAMTS1 in endothelial cells is induced by hypoxia and mechanical stress such as blood wall shear stress. We investigated the effects of tumor interstitial fluid pressure (TIFP) on the expression of ADAMTS1 in the tumor tissues. Stromal ADAMTS1 was mainly expressed in neovascular endothelial cells. It was suggested that stromal ADAMTS1 might implicate in vascular fragility and rarefaction, and elevation of TIFP.
