摘要：

The aim of the present study was to study the expression and activity of trypsin in tissues from patients with cervical cancer and precursor lesions. Immunohistochemistry assays were used to analyze trypsin expression in fixed paraffin-embedded tumor tissues obtained from patients with squamous cervical carcinomas (large-cell keratinizing and non-keratinizing types) and squamous intraepithelial lesions. Proteolytic activity was evaluated in tissue extracts by zymography. Human papillomavirus (HPV) genotyping was performed using PCR. We describe for the first time that trypsin is expressed in invasive squamous cervical carcinomas. Both trypsin expression and proteolytic activity were linked to tumor progression. Our data suggest that trypsin, directly or indirectly, plays a key role in cervical cancer progression.
