Identification of azurocidin as a potential periodontitis biomarker by a proteomic analysis of gingival crevicular fluid

The inflammatory disease periodontitis results in tooth loss and can even lead to diseases of the whole body if not treated. Gingival crevicular fluid (GCF) reflects the condition of the gingiva and contains proteins transuded from serum or cells at inflamed sites. In this study, we aimed to discover potential protein biomarkers for periodontitis in GCF proteome using LC-MS/MS. We identified 305 proteins from GCF of healthy individuals and...
