Sayers, Brooks, Sayers, Chertov: "Increased secretory leukocyte protease inhibitor (SLPI) production by highly metastatic mouse breast cancer cells." in: PLoS ONE, Vol. 9, Issue 8, pp. e104223, (2015) (PubMed).
Secretory leukocyte protease inhibitor (SLPI) is produced at mucosal surfaces, primarily the upper respiratory tract and is thought to play an important role in the antiprotease defense mechanism of the lung. SLPI forms inhibitory complexes with numerous proteolytic enzymes such as neutrophil elastase, and has been shown to possess anti-inflammatory, anti-viral, and antibacterial activities. Its expression in oral epithelial cells is stimulated by HIV-1 gp120, suggesting that SLPI is a component of the oral mucosal response to HIV-1. In peripheral blood monocytes, SLPI can inhibit NF-kB activation by inhibiting IkB degradation in the cytoplasm and competing for NF-kB binding sites in the nucleus. This attenuation of the inflammatory response may also act to suppress liver metastases and other cancer cell invasions, but promote blood-borne metastasis via an invasion-independent pathway.Synonyms: BLPI, HUSI-1, Mucus proteinase inhibitor, Protease inhibitor WAP4, SLPI, Secretory leukocyte protease inhibitor, Seminal proteinase inhibitor, WAP four-disulfide core domain protein 4, WAP4, WFDC4
