Relative galanin (GAL) mRNA expression level by quantitative real-time PCR. (A) Mean GAL expression in 112 colorectal cancers (CRCs) (tumors with recurrence and tumors without recurrence) was significantly higher than that in 27 non-cancerous mucosa (P=0.01). Tumors with recurrence showed higher GAL expression than those without recurrence (P<0.001). (B) Mean GAL expression in stage II CRCs was significantly higher than that in stage III CRCs (P<0.001). Expression was normalized to GAPDH mRNA levels.
