Recently, several molecules other than mesothelin have been found to be potential biomarkers for ovarian carcinoma, such as DF3, vascular endothelial growth factor, MUC1, HE4, and CA19-9 (Cheng et al, 1999; Rosen et al, 2005; Hefler et al, 2006). The gene discussed is WFDC2; the disease is ovarian carcinoma.
