To check if our in vitro findings might have any relevance in human diseases, we examined IL-17A and MTA1 expression in human cervical tissue specimens, including 5 cases of normal cervix, 5 cases of cervical intra-epithelial neoplasia (CIN) I, 5 cases of CIN II, 5 cases of CIN III, and 14 cases of cervical squamous carcinoma. The gene discussed is IL17A; the disease is uterine cervix carcinoma in situ.
