Abstract
Background: Shark cartilage has been considered as a natural anti-angiogenesis material in traditional medicine since long ago, and a broad range of biological functions such as inhibition of endothelial cell adhesion, proliferation, migration and digestion of the extracellular matrix has been reported for it. Because of its widespread therapeutic usage in controlling angiogenesis, we have investigated the antiangiogenesis activity of the shark cartilage proteins, in the present study. Methods: Cartilage proteins were extracted in 100 mM sodium acetate buffer (pH=4.8) containing 4M guanidinium hydrochloride in the presence of protease inhibitors. The extract was then chromatographed on cation and anion exchange columns and the fractions were characterized for angiogenesis properties (like number and thickness of blood vessels, number and severity of bends in accessory vessels and abnormal colour of membrane) using chick chorioallantoic membrane (CAM) assay and gel electrophoresis techniques. Results: The results showed high antiangiogenesis activity of protein fraction A1 extracted from shark cartilage comparing to the controls and other trial groups. Survey on the active protein fraction A1 on gel electrophoresis showed existence of low molecular weight proteins between 14-16 kDa. Conclusion: Shark cartilage has an antiangiogenesis effect. Therefore, considering the importance and increasing needs of novel drugs for angiogenesis-based diseases, further molecular surveys on these angiogenesis proteins are recommended.
