Description

TGF-beta is a multifunctional cytokine affecting many cell types and implicated in tissue remodeling processes. Due to its many functions and cell-specific effects, the consequences of TGF-beta signaling are process-and stage-dependent, and it is not uncommon that TGF-beta exerts distinct and sometimes opposing effects on a disease progression depending on the stage and on the pathological changes associated with the stage. The mechanisms underlying cell- and process-specific effects of TGF-beta are poorly understood. We are describing a novel pathway that mediates induction of angiogenesis in response to TGF-beta1. We found that in endothelial cells (EC) thrombospondin-4 (TSP-4), a secreted extracellular matrix (ECM) protein, is upregulated in response to TGF-beta1 and mediates the effects of TGF-beta1 on angiogenesis. Upregulation of TSP-4 does not require the synthesis of new protein, is not caused by decreased secretion of
