SOX9 and cervical carcinoma: The scatter plot reflects the IHC score of SOX9 staining (Fig. 1C), and the IHC scores of SOX9 were decreased significantly from 5.8±2.7 (n=29) in normal cervical tissues to 4.1±3.0 (n=29) in cervical carcinoma in situ and to 2.4±2.1 (n=39) in cervical invasive carcinoma (P<0.05 between normal cervical tissues versus cervical carcinoma in situ; P < 0.01 between normal cervical tissues versus cervical carcinoma P < 0.05 between cervical carcinoma in situ versus cervical carcinoma).
