Consistent with these results, immunohistochemistry (IHC) studies showed that both the immunosignal intensity and positivity of YAP1 protein significantly increased with grades of cervical intraepithelial neoplasia (CIN) (n = 7 for normal control, n = 28 for CIN1, n = 23 for CIN2, n = 29 for CIN3; Figures S2A–S2D). This evidence concerns the gene YAP1 and cervical squamous intraepithelial neoplasia.
