Bouchard et al.[11] reported that SLPI expression is highly upregulated in pancreatic, papillary thyroid, uterine cervix, endometrial, and ovarian cancer; by contrast, SLPI is underexpressed in nasopharyngeal carcinoma, bladder tumors, and some breast carcinomas, although overexpression of this protein correlates with more invasive forms of breast carcinoma. Here, SLPI is linked to ovarian carcinoma.
