Expression of the URG4 protein in cervical cancer tissues from patients at different clinical stages. (a) Representative images from immunohistochemical analyses of URG4 expression in normal cervical tissues and cervical cancer tissues at different clinical stages. (b) The statistical analyses of the average mean optical density (MOD) of URG4 staining in normal cervical tissues and cervical cancer specimens at different clinical stages. (c) The statistical analyses of the average MOD of URG4 staining in the lymph node metastasis group and the lymph node metastasis-free group. *P < 0.05.
