UCA1 expression level is positively correlated with MMP9 level of villi tissues derived from RM patients or HCs. a–c The mRNA levels of UCA1, MMP2, and MMP9 of the villi tissues collected from RM patients (n = 43) or HCs (n = 37) were detected by quantitative RT-PCR. d The mRNA level of MMP2 of the villi tissues isolated from RM patients and HCs was evaluated by quantitative RT-PCR. The potential correlation with the UCA1 level in the villi tissues from RM patients (n = 43) and HCs (n = 37) were analyzed. e The mRNA level of MMP9 in collected villi tissues of RM patients and HCs was examined by quantitative RT-PCR. The positive correlation with the level of UCA1 expression in RM patients (n = 43) and HCs (n = 37) were observed
