Abstract:
ObjectiveTo evaluate the relationship of human papillomavirus(HPV) intection with expressions of cell cycle regulatory proteins cyclin D1,E and their dependent kinase inhibitor p27 in bowenoid papulosis(BP).MethodsTissue specimens were obtained from the lesions of 44 patients with BP,and circumcised foreskin tissue from 10 males served as the control.Gene chip was used to determine the genotypes of HPV,and immunohistochemistry to quantify the expressions of cyclin D1,E,p27,in these specimens.Results Of the 44 BP specimens,all were positive for HPV DNA,38(86.36％) for high risk types of HPV,and 6 for low risk types of HPV.Of the high risk HPV-positive specimens,30(68.18％) harbored HPV16,16 harbored single HPV 16,14 harbored other types of HPV besides HPV 16,8 harbored other high risk types of HPV.HPV 6 predominated in low risk HPV-positive specimens.The expression of cyclin D1 was significantly higher in patients with high-risk HPV(u =53.00,P＜ 0.05),with both high and low risk HPV(u =5.00,P＜ 0.01) and with low risk HPV (u =22.50,P＜ 0.05) than in normal human controls,and higher in patients with both high and low risk HPV (u =44.00,P＜ 0.01) and with low risk HPV (u =22.50,P＜ 0.05) than those with high risk HPV.In the case of cyclin E expression,patients with high risk HPV (u =0.00,P ＜ 0.01 ),with both high and low risk HPV (u =4.00,P ＜ 0.01 ),and with low risk HPV(u =1.50,P ＜ 0.01 ) were higher than normal human controls,and patients with high risk HPV were higher than those with low risk HPV(u =11.00,P ＜ 0.01).No significant difference was observed in the expression of p27 between patients with high and low risk types of HPV.A significant increase was observed in the expression of p27 in patients aged ＞ 50 years compared with patients aged 20-30 years(u =47.00,P＜ 0.05) and aged 31-50 years (u =55.50,P＜ 0.05),as well as in the expression of cyclin E in patients aged ＞ 50 years compared with those aged 20-30 years(u =45.50,P ＜ 0.05),and in female patients compared with male patients (u =137.50,P＜ 0.05).ConlusionThere is a significant difference in the expression of cyclin D1,E and p27 among patients with BP infected with different types of HPV.
