To rule out the possibility that the 14 potential biomarkers identified in this study (6Ckine, CD14, CEACAM-1, ENA-78, ERBB3, IL-7, I-TAC, LAP (TGF-β), Lipocalin-2, MCP-1, NrCAM, RAGE, TARC, TNF-β) are nonspecific to other inflammatory gynecological conditions, we also compared the differential expression of the 14 proteins between 52 healthy controls with 5 polycystic ovarian syndrome patients (PCOS), 6 pelvic adhesion patients, and 15 ovarian cyst patients. The gene discussed is NRCAM; the disease is Ovarian cyst.
