title: [Expression of Daxx and HPV16 E6 and its significance in cervical lesions].
abstract: OBJECTIVE
  To investigate the expression of death domain associated protein (Daxx) and human papillomavirus 16 E6 protein (HPV16 E6) in cervical lesions and analyze their significance.
  
  
  METHODS
  Immunohistochemical SABC method was used to detect the expression of Daxx and HPV16 E6 in 194 cases of cervical tissues with different lesions.
  
  
  RESULTS
  (1) The positive expression rate of Daxx was 28.57% (12/42), 40.00% (18/45), 65.91% (29/44), 66.67% (42/63), respectively, in chronic cervicitis, cervical intraepithelial neoplasia I-II (CIN I-II), CIN III and cervical squamous cell carcinoma. The positive expression rate of HPV16 E6 was 15.38% (6/39), 36.17% (17/47), 46.30% (25/54), 100.00% (24/24) in the above four groups. The positive rates in cervical cancer group and high grade CIN group were significantly higher than these in low level of CIN group and chronic cervicitis group (P<0.05). (2) The expression of Daxx was stronger in HPV16 E6 high positive group than that in HPV16 E6 low positive group (P<0.05). (3) There was no significant relationship between the expression of Daxx and pathological classification, clinical stage, situation of lymph node metastasis or patients' age in cervical squamous cell carcinoma (P>0.05). (4) There was significant positive relationship between Daxx and HPV16 E6 expression (r=0.695, P<0.05).
  
  
  CONCLUSIONS
  The expression of Daxx and HPV16 E6 gradually increases with cervical lesion degree aggravating. Here might be synergy between them, and both could promote the development of cervical lesions.
