EZR and cervical squamous intraepithelial neoplasia: We first performed immunohistochemistry for ezrin protein in 543 samples of paraffin-embedded cervical lesions, and found that the positive rate of ezrin protein was only 11.5% (6/52) in non-neoplastic cervical tissues, but higher in CIN lesions (85.4%, 204/239), in which it was 81.5% (53/65) in CIN-1, 84.3% (86/102) in CIN-2 and 90.3% (65/72) in CIN-3.
