FIGURE 1.

Snail and E-cadherin expression in cervical carcinoma tissues determined by immunohistochemical staining (original magnification × 200). (A) Representative Snail expression in tumor and normal tissues, with positive expression located in the cytoplasm. (B) Scatter dot plot showing the staining score (mean ± SEM) of Snail in tumor and normal tissues using the paired t-test. *P < 0.001; (C) Representative E-cadherin expression in tumor and normal tissues, with positive expression located in the membrane and cytoplasm. (D) Scatter dot plot showing the staining score (mean ± SEM) of E-cadherin in tumor and normal tissues using the paired t-test. *P < 0.001; (E) Snail expression was negatively correlated with E-cadherin expression in 203 patients with cervical carcinoma.
