Dynamic proteome in enigmatic preeclampsia: an account of molecular mechanisms and biomarker discovery.

The coevolution of genomics and proteomics has led to advancements in the field of diagnosis and molecular mechanisms of disease. Proteomics is now stepping into the field of obstetrics, where early diagnosis of pregnancy complication such as preeclampsia (PE) is imperative. PE is a multifactorial disease characterized by hypertension with proteinuria, which is a leading cause of maternal and neonatal morbidity and mortality occurring in 5-7% of pregnancies worldwide.

Effect of maternal micronutrients (folic acid, vitamin B12) and omega 3 fatty acids on liver fatty acid desaturases and transport proteins in Wistar rats.

A disturbed fatty acid metabolism increases the risk of adult non-communicable diseases. This study examines the effect of maternal micronutrients on the fatty acid composition, desaturase activity, mRNA levels of fatty acid desaturases and transport proteins in the liver. Pregnant female rats were divided into 6 groups at 2 levels of folic acid both in the presence and absence of vitamin B(12).

Reduced placental docosahexaenoic acid levels associated with increased levels of sFlt-1 in preeclampsia.

Our earlier studies, in preeclamptic women have shown altered levels of long chain polyunsaturated fatty acids (LCPUFA), essential constituents of the cell membrane lipids responsible for membrane stability as one of the key factors contributing to the pathophysiology of preeclampsia. We have also reported elevated levels of sFlt-1 in preeclampsia. The present study examines the levels of LCPUFA and their association with sFlt-1 levels in 69 pre-eclamptic women and 40 normotensive women.

Circulating angiogenic factors and their association with birth outcomes in preeclampsia.

This study was designed to test the hypothesis that altered angiogenic factors together with increased oxidative stress and reduced docosahexaenoic acid (DHA) levels may be associated with altered birth outcome parameters. To test this hypothesis, levels of plasma vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1), the oxidative stress marker malondialdehyde (MDA) and fatty acids were estimated in women with preeclampsia and their cord samples and compared with those in normotensive women. The association of these parameters with birth outcome was also examined.

Long-chain polyunsaturated fatty acid composition of breast milk in pre-eclamptic mothers.

Background: Maternal fatty acid nutrition during pregnancy and lactation determines the transfer of long-chain polyunsaturated fatty acids via the placenta and through human milk. Neural maturation of breast-fed infants is known to be linked to breast-milk long-chain polyunsaturated fatty acid concentrations. In spite of this, the fatty acid composition of breast milk in pre-eclamptic mothers is poorly understood.
