CGA and neoplasm: Also, low‐dose vasostatin‐1 can delay tumor growth and reduce microvessel density in murine models of solid tumors.41 In these models, neutralization of endogenous murine CgA with antibodies against its C‐terminal region enhances tumor growth rate, whereas systemic administration of low amounts of hCgA1–439 reduces tumor growth.178 It appears, therefore, that circulating full‐length CgA and vasostatin‐1 can work as physiological inhibitors of tumor growth.
