Abstract

The demonstration that type 2 transglutaminase (TG2) can incorporate polyamine into the E7 oncoprotein of human papillomavirus (HPV) type 18 has led to the hypothesis that TG2 can have a role in the host cellular response to HPV infection. The aim of this study was to investigate whether HPV-related pathology, in infected human cervical epithelium, was associated with modulation of TG2 expression. Normal controls and HPV-infected cervical biopsies were analyzed for the expression of TG2, and the findings were compared with lesion grade. The correlation between TG2 expression and p16, a marker for HPV-induced dysplasia, and the retinoblastoma protein (Rb), a target of the E7 protein of HPV, was also investigated. Results obtained showed that TG2 was absent in normal squamous mucosa, whereas it was present in 100% CIN I lesions. Low-grade lesions showed significantly higher TG2 expression than high-grade lesions (P
