Summary

Insulin-like growth factor binding protein 7 (IGFBP7), also known as mac25 or IGFBP-related protein-1 (IGFBP-rP1), is a secreted protein belonging to the insulin-like growth factor (IGF) system. The IGF axis plays a key role in normal growth and development, and in pathophysiology of various cancers in mammals.
IGFBP7 is expressed in a variety of normal tissues including heart, spleen, ovary, small intestine and colon and has been found in biological fluids, such as serum, urine, CSF and amniotic fluid. While normal tissues express IGFBP7 abundantly, no or very weak IGFBP7 expression is detected in many cancers. Its expression is lost upon progression to more aggressive cancer types and loss of IGFBP7 expression is associated with poor prognosis. , IGFBP7 has been shown to be a tumor suppressor for solid cancer such as breast, colorectal, hepatocellular, prostate and thyroid cancer, melanoma and glioma. Reexpression of IGFBP7 or exposure of cancer cell lines to IGFBP7 results in either senescence or apoptosis. Overexpression of IGFBP7 significantly inhibited growth of cancer cells both in vitro and in vivo, thus, IGFBP7 could be a novel therapeutic target in cancer therapy.
In addition it was discovered, that IGFBP7 and tissue inhibitor of metalloproteinases-2 (TIMP-2) are two novel biomarkers for identification of moderate to severe acute kidney injury (AKI) in critically ill patients.
