ABSTRACT
OBJECTIVES:
Persistent infection with human papillomavirus causes cervical high-grade squamous intraepithelial lesions (HSILs). The role of antimicrobial peptides (AMPs) in premalignant and malignant transformation is not fully understood. In this study, we examined the expression of human ß-defensin 1 (HBD-1), HBD-2, HBD-3, LL37, psoriasin, and interleukin 8 (IL-8) in women with HSIL before and 6 months after surgery. MATERIALS ANDMETHODS:
Biopsies and secretion samples from the cervical canal were collected from 19 patients with HSIL and 14 healthy controls. The mRNA expression of HBD-1, HBD-2, HBD-3, LL37, psoriasin, and IL-8 was analyzed before and 6 months after surgery excision using reverse transcriptase real time polymerase chain reaction. For protein analyses, ELISA and immunohistochemistry were used for psoriasin and ELISA for IL-8.RESULTS:
The mRNA expression of psoriasin was lower in patients before treatment compared with healthy controls (p = .05). After surgery, when the infection was cleared, psoriasin increased on mRNA (p = .04) and protein (p = .03) levels compared with before treatment. Immunostaining for psoriasin after treatment was prominent and localized in the cytoplasm of the epithelial cells. After treatment, IL-8 mRNA was reduced compared with before treatment (p = .05), but not on the protein level. No changes in mRNA expression of the other AMPs analyzed were observed in pretreatment and posttreatment samples.CONCLUSIONS:
In this study of AMP expression in human papillomavirus-induced HSIL, we observed lower psoriasin levels before surgery compared with after treatment, when both mRNA and protein levels were similar to healthy controls. Interleukin 8, on the other hand, was increased before treatment, indicating an inflammatory response.
