Preeclampsia (PE) is the leading cause of maternal and fetal morbidity and mortality. It complicates around 2%–10% pregnancies worldwide due to imbalance between proangiogenic and anti-angiogenic factors, leading to incomplete placentation, ischemia, and endothelial dysfunction. The study was aimed to analyze the mRNA expression of vascular endothelial growth factor (VEGF) and its receptors, i.e., VEGF receptor-1 (VEGFR-1), VEGF receptor-2 (VEGFR-2), and soluble Fms-like tyrosine kinase-1 (sFlt-1) from maternal peripheral blood mononuclear cells (PBMCs) of PE patients. This was a cross-sectional comparative study comprising 18 normotensive and 18 PE patients; the patients were further divided as early-onset preeclampsia (EOP) and late-onset preeclampsia (LOP). The expression level of VEGF, its receptors (VEGFR-1 and VEGFR-2), and sFlt-1 was investigated using real-time polymerase chain reaction. There was a significant change in the mRNA expression with a decrease in VEGF, VEGFR-1, and VEGFR-2 and an increase in sFlt-1 in PBMCs of PE and normal pregnancies (P < 0.001). sFlt-1 mRNA expression was increased by 2.95-fold in the PE group with an inverse correlation with expression of VEGFR-2 (Spearman's rho = 0.68). Based on these findings, we conclude that PE is associated with decrease in the mRNA expression of VEGF, VEGFR-1, and VEGFR-2 as compared to an increase in sFlt-1 in PBMCs.
