Endostatin Biomarker Spotlight
Endostatin is an endogenous angiogenesis inhibitor localized in the vascular basement membrane in various organs. The biological functions of the endostatin-network involve SPARC, thrombospondin-1, glycosaminoglycans, collagens, and integrins. Endostatin is expressed during the progression of renal fibrosis in tubular cells of injured tissue.

A recent study aimed to discover the role of endostatin in in the dysregulation of angiogenesis in patients with kidney and heart failure. Scientists found that due to its capability to inhibit angiogenesis and tumor growth, endostatin is highly involved in these processes in chronic kidney disease and heart failure. Since endostatin is not just a biomarker of angiogenesis but also a hormone regulating these processes, pharmacologic intervention in this system might offer new therapeutic options in the future.
