Expression of DKK1 in individual tissues from patients with URSM and healthy pregnancy. A, DKK1 mRNA expression as measured by quantitative real-time RT-PCR in patients with URSM and control group. B, Correlative analysis of DKK1 mRNA levels in individual decidual tissue samples and serum DKK1 levels by Spearman's correlation test (2-tailed). C, Each DKK1 intensity was divided by the corresponding intensity of β-actin from the same tissue sample to adjust for the sample variation. D, Increased DKK1 protein expression was present in URSM decidual tissues than the control. E, Among 59 study subjects, high expression of DKK1 protein was significantly correlated with the serum DKK1 levels.
