Abstract

Over the past two decades, emerging data have found that YKL-40, a secreted glycoprotein, is elevated in a broad spectrum of human diseases including cancers, liver injury, asthma, diabetes, inflammatory diseases, and cardiac disorders. In breast cancer, increased serum levels of YKL-40 are correlated with cancer metastasis and short survival, suggesting that serum levels of YKL-40 serve as a cancer biomarker. YKL-40 has the ability to stimulate vascular endothelial cell activation and suppress mammary epithelial cell differentiation, the pathophysiological events associated with tumor angiogenesis and poor differentiation. Neutralization of YKL-40 via an anti-YKL-40 monoclonal antibody in animal trials demonstrates the ability of YKL-40 blockade to impede tumor angiogenesis and tumor growth, thus holding therapeutic promise for cancer therapy. Apart from these findings, substantial efforts are urgently required to decipher the key molecular mechanisms that mediate cancer metastasis and malignancy, which is expected to significantly offer translational value for breast cancer diagnosis, prognosis and therapy. This review discusses the current status of research on YKL-40’s expression, biophysiological and pathological activities and functional inhibition, which is instrumental for future clinical practice.
