Salvianolic acid B promotes the invasion and migration of HO-induced HTR-8/Svneo trophoblast cells by upregulating matrix metalloproteinase-9 the phosphatidylinositol-4,5-bisphosphate 3-kinase/protein kinase B pathway.
Objective: To elucidate the regulatory effects of salvianolic acid B (SalB) on trophoblast cells in preeclampsia (PE).
Methods: 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenylte-trazolium bromide (MTT) assays were used to detect the viability of human extravillous trophoblast HTR-8/Svneo cells induced by HO following treatment with different concentrations of SalB. The levels of oxidative stress-related molecules, including superoxide dismutase, glutathione-Px and malondialdehyde were detected using corresponding kits. Cell apoptosis was detected using a Terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling (TUNEL) assay, and the expression of apoptosis-related proteins was detected using western blot analysis. In the present study, wound healing and Transwell assays were performed to measure the levels of cell invasion and migration. Western blot analysis was also used to detect the expression levels of epithelial-mesenchymal transition-related proteins. The mechanisms underlying SalB were further investigated using reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and western blot analysis, to determine the expression levels of matrix metallopeptidase 9 (MMP-9) and phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/protein kinase B (Akt).
Results: SalB increased the activity of HTR-8/Svneo cells, inhibited oxidative damage and promoted the invasion and migration of trophoblast cells induced by HO. Furthermore, the expression levels of MMP-9 and members of the PI3K/Akt signaling pathway were significantly decreased. The pathway agonist, LY294002, and MMP-9 inhibitor, GM6001, reversed the effects of SalB on HO-induced cells.
Conclusions: SalB promoted the invasion and migration of HO-induced HTR-8/Svneo trophoblast cells by upregulating MMP-9 the PI3K/Akt signaling pathway.
