Overall, for themajority of proteins, staining was higher in carcinomas compared with ovariansurface epithelium, and in most cases (with the exception of EPCAM), staining incarcinomas was at a similar level to that seen in fallopian tube epithelium.LCN2 staining was not detected at significant levels in the ovarian cancercohort or in the epithelium of normal tissues, despite expression beingincreased in ovarian tumors in two expression array analyses [15], [18]. The gene discussed is EPCAM; the disease is carcinoma.
