Figure 1

Bmi-1 and HMGA2 expressions in head and neck squamous cell carcinoma (HNSCC) clinical samples. mRNA expression levels in 38 cases of HNSCC. The relative mRNA expression levels in tumor tissues (T: dark gray/black bar) and their corresponding non-cancerous background tissues (N: gray bar) in each of the 38 cases are shown in the right panel. Samples 1–13 are from well-differentiated HNSCCs; 14–30 from moderately differentiated HNSCCs; 31–38 from poorly differentiated HNSCCs. (a) Bmi-1 and (b) HMGA2. The average expression level of Bmi-1 was slightly higher in tumor tissues than in non-cancerous background liver tissues (13.27 vs 13.07; *P=0.96; left panel). The average expression level of HMGA2 was significantly higher in tumor tissues than in non-cancerous background squamous epithelium (6.05 vs 0.77; **P<0.01; left panel).
