Comparison of miR-30d-5p and SOCS1 expression in endometrium samples from the RIF and control groups. A The relative expression level of LIF mRNA in the RIF group (n = 20) and the control group (n = 10), as detected via RT-qPCR; GAPDH was used as an internal control for LIF. B The relative expression levels of LIF, p-STAT3 and STAT3 protein in the RIF group (n = 20) and the control group (n = 10), as detected via western blotting; GAPDH was used as internal control. C, D Data of expression of LIF and p-STAT3 protein were expressed as mean ± SD. *P < 0.05
