Relationship between REG4 mRNA expression and clinicopathological features of ovarian cancer. REG4 mRNA expression was quantified by real-time RT-PCR in normal ovarian tissue (No; n = 17), benign (Be; n = 10) and borderline (Bo; n = 6) tumors, primary (Ca; n = 66) and metastatic cancers in the omentum (Om; n = 21). aREG4 mRNA expression levels are significantly higher in both benign ovarian tumors and primary carcinoma compared to normal ovarian tissue. b Mucinous (Mu) tumors show higher REG4 mRNA expression levels than serous (Se) tumors; and Mann-Whitney U test showed that REG4 mRNA expression is higher in well- and moderately-differentiated tumors than in poorly-differentiated tumors (c), but there was no significant difference between (d) FIGO staging I–II & III–IV; *P < 0.05
