To evaluate STING expression in HPV-associated premalignancies, we performed immunohistology of high grade cervical intraepithelial neoplasia (CIN3), high grade anal intraepithelial neoplasia (AIN3), and condyloma, as well as benign hyperplasia and tissues from normal uterus as a control. The gene discussed is STING1; the disease is cervical intraepithelial neoplasia.
