Transforming growth factor-Pl (TGF-Pl) is a potent growth inhibitor of epithelial cell growth, but can also stimulate stromal cell growth. Loss of responsiveness to TGF-/)l or loss of TGF-P1 itself may be important in the progression of cervical intraepithelial neoplasia (CIN) to invasive cervical c

Abstract
Overexpression of kallikrein 7, a proteolytic enzyme important for epithelial cell shedding, may be causally involved in carcinogenesis, particularly in tumor metastasis and invasion. In this study, we have evaluated hK7 (human kallikrein 7) protein levels by immunohistochemistry in 367 cervical histological samples including 35 cases of cervicitis, 31 low‐grade cervical intraepithelial neoplasia, 51 high‐grade cervical intraepithelial neoplasia (H‐SIL), 197 squamous cervical carcinomas (SCC) and 53 cervical adenocarcinomas. We have observed that hK7 staining increased with the severity of cervical disease. Intense hK7 staining was found in 15.2% of cervicitis samples, in contrast to 55% of H‐SIL and 68% of SCC. Moreover, 92.5% of adenocarcinomas also exhibited intense hK7 staining. Differences in the expression of hK7 could potentially be used as a biomarker for the characterization of different stages of cervical disease.
