The primary objective of this study was to explore whether antisense oligonucleotides (ASOs) that reduce LncNR_040117 expression in patients with antiphospholipid antibody syndrome (APS)-induced recurrent pregnancy loss (RPL), and further decrease apoptosis and improve trophoblasts invasion through mitogen-activated protein kinase (MAPK) pathways. This paper aimed to provide a new strategy to treat APS-induced RPL. In this study, we used quantitative reverse transcription-polymerase chain reaction (RT–qPCR) to analyze the expression level of LncNR 040117 in HTR-8/SVneo cells following transfection with ASOs. Then we utilized Western blotting to test the expression levels of interleukin-1β (IL-1β), intracellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and key molecules of MAPK pathways, including the extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinases (JNK) and p38. In addition, we examined the HTR-8/SVneo cells apoptosis by cell apoptosis assay, and migration and invasion by transwell antibody assay. Each experiment was repeated three times. The data are presented as the means ± SDs, and statistical comparisons were performed using Student’s t-test. p < 0.05 was considered significant. Transfected with ASOs, LncNR_040117 was downregulated in trophoblasts compared with APS-induced RPL patients. And LncNR_040117 low expression induced IL-1β and downstream adhesion molecules ICAM-1 and VCAM-1expression level decreased, as well as MAPK pathways downregulation, including the ERK pathway, JNK pathway and p38/MAPK pathway. Furthermore, all these changes resulted in decreased apoptosis and increased migration and invasion of trophoblasts. This study indicated that ASOs that decrease LncNR_040117 expression can reduce apoptosis and enhance the invasion and migration of trophoblasts by regulating the MAPK pathway.
