Abstract:
ObjectiveThe relationship between glycosaminoglycans sulodexide (SDX) and HDP such as preeclampsia (PE) has not been reported. The purpose of this study is to observe the protective effect and molecular mechanism of SDX on the function damage of human umbilical vein endothelial cells induced by pregnancy serum of PE.Methodsthe indicated concentrations of SDX (0, 0.1, 0.3, 1, 3, 10, 30 LSU/mL) were used to interfere with HUVEC and Ea.hy926 cells. CCK8 and Matrigel methods were used to detect cell proliferation and tube formation. The normal pregnant women serum (NPS) or PE patients serum (PES) which collected at the 12 th week of pregnancy and the effective concentration of SDX were used to intervene the cells. Matrigel methods were used to observe the protective effect of SDX on endothelial function damage which induced by pathological serum. The secretion level of sFLT-1 and PlGF in supernatant were determined by ELISA.ResultsCompared with the control group, high concentration of SDX inhibited the proliferation of endothelial cells. SDX significantly promoted the tube formation activity wiht a peak at 0.3 LSU/mL (P<0.01). PES damaged the tube formation activity. 0.3 LSU/mL SDX protected cells from tube formation damage which induced by PES (P<0.01). PES promoted the secretion of sFLT-1 and inhibit the secretion of PlGF, while 0.3 LSU/mL SDX reversed the secretion of sFLT-1 and PlGF induced by PES (P<0.01).Conclusion0.3 LSU/mL SDX can protect endothelial cells from PES induced endothelial dysfunction, which is associated with the secretion balance regulation of sFLT-1 / PlGF.
