Tissue leptin and LepRb levels in gastric cancer patients. Leptin and LepRb levels in patients' tissue were detected by real-time RT-PCR. (a, b) PCR melting curve. (c, d) mRNA levels were indicated for leptin and LepRb. (e) Correlation of leptin in serum and cancer tissue at individual patients. ∗Compared with paracarcinoma tissue, ∗P < 0.05. #Compared with nondepressive gastric cancer, #P < 0.05.
