STAT3 and cervical intraepithelial neoplasia: Aligned with our results, other studies evaluating STAT3 activation (via pY705 or pS727) on tissue samples of other cancer types such as cervical intraepithelial neoplasia (CIN) and prostate cancer, have also reported a significant correlation of pS727-STAT3 levels to the clinical outcome of those patients18,19.
