RELA and cervical squamous intraepithelial neoplasia: Notably, we found that p-RELA expression in the cytoplasm significantly increased from the stage of simple hyperplasia in cervical epithelial cells, accompanied by a gradual increase in nuclear expression throughout the transition from CIN to CSCC (with nuclear positivity rates of 90%, 97%, 99%, 100%, and 100%, respectively) (Figure 1D–F).
