SOX11 protein expression in the nasopharyngeal carcinoma and chronic inflammation tissues. Tm: SOX11 gene methylated nasopharyngeal carcinoma tissues; Tu: SOX11 gene unmethylated nasopharyngeal carcinoma tissues; Ci: Chronic inflammation tissues in pharynx nasalis. The electrophoretogram showed that weak expression of SOX11 protein was found in the nasopharyngeal carcinoma tissues with SOX11 gene promoter methylation, strong expression of SOX11 protein was found in the chronic inflammation tissues and nasopharyngeal carcinoma tissues with SOX11 gene promoter unmethylation.
