What is endostatin?

Endostatin is a naturally occurring protein that acts as an inhibitor of angiogenesis, the process through which new blood vessels form from existing ones. It is a fragment of collagen XVIII and has been studied for its potential in cancer therapy, as it can impede tumor growth by restricting the blood supply necessary for cancer cells to thrive. Research has also explored its role in various other conditions involving abnormal blood vessel formation. Overall, endostatin represents a promising area of investigation in the field of anti-cancer treatments.
