Abstract | OBJECTIVE: METHODS: Twenty-six placenta tissue samples from pregnant women with severe preeclampsia (study group), and 20 samples from normal pregnancies (control group) were obtained. We detected the expression of relaxin receptor by immunohistochemistry and the expression of relaxin receptor mRNA by RT-PCR. RESULTS: In the placenta of control and preeclampsia groups, the leucine-rich repeat-containing G protein-coupled receptor (LGR7) was positively expressed. Relaxin receptor was located in the membrane of trophoblast cells. There were both strong signals on cytotrophoblastic cells and syncytiotrophoblast. The level of relaxin receptor in the control group was 0.912 +/- 0.003, and 0.625 +/- 0.037 in the preeclampsia group. The difference between the two groups was obvious (P < 0.01). In the control group, the level of relaxin receptor mRNA was 0.776 +/- 0.021; in the preeclampsia group, it was 0.393 +/- 0.075. The difference was obvious (P < 0.01). CONCLUSION:
