In 2011, Rajkumar et al. observed that STAT1 was overexpressed in cervical intraepithelial neoplasia (CIN) 1 and 2 as well as in invasive cancers; however, in CIN3 and cervical carcinoma in situ (CIS), there was a decrease in STAT1 expression [155]. The gene discussed is STAT1; the disease is in situ carcinoma.
