title: [A novel antiapoptosis gene, survivin, bcl-2, p53 expression in cervical carcinomas].
abstract: OBJECTIVE
  To study the expression of a novel inhibitor gene of apoptosis, survivin, in cervical carcinoma and its relationship with the expression of bcl-2, p53 genes.
  
  
  METHODS
  Using streptavidin-biotin peroxidase (SP) method, we examined the expression of survivin, bcl-2 and p53 genes in 10 normal cervical tissues and 59 cervical carcinoma tissues.
  
  
  RESULTS
  Survivin was expressed in 41 of 59 (69.5%) cases of cervical carcinomas. In contrast, normal cervical epithelium did not express survivin. Overexpression of survivin was related to the tumor grade and clinical stage. Survivin positive cases were strongly associated with bcl-2 expression (36/45, 80.0% versus 5 of 14 cases, P < 0.005) and p53 expression (33/43, 76.7% versus 8 of 16 cases, P < 0.05).
  
  
  CONCLUSIONS
  Apoptosis inhibition by survivin, alone or in cooperation with bcl-2 and p53 may participate in the onset and progression of cervical carcinoma. Survivin could be a new diagnostic/therapeutic target in cervical cancer.
