Fibulin-5 secreted by tumor-associated fibroblast blocks the interaction of fibronectin and integrin, which leads to a decrease or block of ROS (Reactive Oxygen Species) production resulting in increased angiogenesis and tumor growth. In contrast, in the absence of fibulin-5 and integrin interaction in normal cells, increased ROS production results in decreased angiogenesis and tumor growth.
