Regardless of tumor sites, paired t-test analysis of tumor and healthy tissues from all 41 patients indicated significant expression changes in nine genes including ACLY (p = 0.00110), CDC20 (p = 0.00007), KRT14 (p = 0.00031), MCM2 (p = 0.00011), MKI67 (p = 0.00004), SKP2 (p = 0.00012), SLC2A1 (p = 0.00012), SNAI2 (p = 0.000862), and STMN1 (p = 0.00031) (Table 1). This evidence concerns the gene MCM2 and neoplasm.
