Association between Expression of HDAC1 Protein and HPV16/18 Infection in Cervical Intraepithelial Neoplasia and Cervical Squamous Cell Carcinoma

Objective To explore the anomalous expression of HDAC1 in cervical intraepithelial neoplasia(CIN)and cervical carcinoma and its relationship with the infection of HPV16/18. Methods The expressions of HDAC1 protein and HDAC1 infection were detected by in situ hybridization(ISH)and immunohistochemistry staining(SP)in tissues from patient with chronic cervicitis(the chronic cervicitis group),CIN(the CINⅠ group,the CINⅡ group and the CINⅢgroup)and cervical squamous carcinoma(the cervical carcinoma group). Results The infection rate of HPV16/18 was 8.33%,34.78%,48.00%,65.21%,78.00% in patients with chronic cervicitis,CINⅠ,CIN Ⅱ,CINⅢ and cervical carcinoma respectively. There was significant difference between groups(P 0.05). The positive expression rate of HDAC1 was 0,13.04%,32.00%,47.82%and 76.00% in chronic cervicitis,CIN Ⅰ,CINⅡ,CINⅢ and cervical carcinoma,respectively. The differences were statistically significant(P 0.05). The positive expression of HDAC1 in the HPV16/18 infected patients was significantly higher than those uninfected with HPV16/18(P 0.05). The HDAC1 positive expression had no relationship with clinical stages of cervical carcinoma,however,it was related to the tissue differentiation,stromal invasion and pelvic lymph node metastasis(all P 0.05). Conclusion The infection of HPV16/18 may play an important role in the carcinongenesis of SCC through increasing the expression of HDAC1.
