Summary: Preeclampsia is a dangerous complication of pregnancy that can lead to maternal death and long-term complications. This study aimed to find new compounds to reduce placental sFlt-1 and discovered that luteolin showed the most potent inhibition of sFlt-1 release, with over 95% reduction. Luteolin was found to reduce sFlt-1 through inhibition of HIF-1 alpha, possibly via the Akt pathway.

Summary: This study suggests that sFlt-1 may be useful in predicting the timing of pregnancy termination in patients with preeclampsia. However, further research is needed to confirm these findings and determine the optimal timing for pregnancy termination in order to reduce severe maternal complications.

Summary: This study found that using placental-specific sFLT-1 e15a performs comparably to total sFLT-1 in diagnosing preeclampsia, which is particularly helpful in diagnosing early-onset preeclampsia.

Summary: Preeclampsia is a serious complication of pregnancy that can lead to maternal death and long-term complications. This study aimed to identify new compounds that can reduce sFlt-1 and inhibit HIF-1a, a prohypertensive factor. The natural compound luteolin showed the strongest inhibition of sFlt-1 release, with over 95% reduction compared to the control group. Luteolin also reduced HIF-1a expression through the Akt pathway. This makes luteolin a potential novel treatment for preeclampsia.

Summary: The early identification of women at risk of preeclampsia is important, and this study aimed to determine relevant biomarkers for predicting preeclampsia. Serum creatine kinase, soluble tyrosine protein kinase receptor (sTIE2), and anti-angiogenic factor soluble c-Met (sMet) were found to be significantly different between women with and without preeclampsia, indicating their potential as biomarkers. However, other kinases and phosphatases were not found to be different between the two groups. Rating: 7

Summary: This study tested the link between altered PlGF and sFLT-1 levels, and their ratio with PE and PE-associated features, and found that increased sFlt-1 levels and sFlt-1/PlGF ratio are independent risk factors for PE.

Summary: Aspirin reduces trophoblast apoptosis in preeclampsia by inactivating the NF-kappa B signaling pathway and reversing endothelial dysfunction and oxidative stress caused by sFlt-1. This treatment significantly improves the condition of patients with preeclampsia.

Summary: This study developed a new model of preeclampsia by modulating the circulating protein sFlt-1 associated with the pregnancy complication using a safe and effective approach. The new model shows promise for testing and developing treatments for preeclampsia.

Summary: Human alpha(2)-macroglobulin (h alpha M-2) is a large homotetrameric protein involved in the broad inhibition of endopeptidases. After cleavage, h alpha M-2 undergoes conformational changes and eventually entraps the peptidase through a Venus flytrap mechanism. Biochemical and biophysical characterization of purified h alpha M-2 from fresh or frozen plasma showed no differences in molecular or functional properties, indicating that native h alpha M-2 remains functional despite freezing.

Summary: sFlt-1 is associated with various angiogenesis-related diseases, such as pre-eclampsia, perinatal cardiomyopathy, diabetic nephropathy, hypertension, tumor, atherosclerosis, etc. Its regulatory mechanisms in these diseases are mainly related to the bioavailability of VEGF and vascular endothelial cell integrity.

Summary: This study investigated the effect of the proton pump inhibitor omeprazole on circulating levels of sFlt-1, PlGF, and ET-1 in women with confirmed preeclampsia. The results showed that omeprazole did not alter these levels, suggesting that it is not a suitable treatment for this syndrome.

Summary: A2M is an antiproteinase that plays an inhibitory role by trapping proteinases with its unique cage structure. Its synthesis increases in inflammatory diseases and it can trap various proteinases involved in coagulation and fibrinolysis. Therefore, A2M plays an important role in the balanced regulation of hemostasis.

Summary: Alpha-2-macroglobulin is known for its role as a broad-spectrum protease inhibitor and has additional functions such as regulating proteolysis, promoting cell migration, and binding cytokines, especially crucial in immune-cell function. This review provides an overview of all functions of Alpha-2-macroglobulin in the context of inflammation, immunity, and infections.

Summary: Preeclampsia (PE) is characterized by new onset hypertension in association with placental ischemia, reduced fetal weight, elevated soluble fms-like tyrosine kinase-1 (sFlt-1), and placental mitochondrial (mt) dysfunction and oxidative stress. This study demonstrates that sFlt-1 induced hypertension during pregnancy reduces placental mitochondrial function, but treatment with PIBF improves placental mitochondrial function and hypertension, suggesting the efficacy of enhanced progesterone signaling as a potential therapy for PE.
