    ABSTRACT: 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. This review discusses the probable molecular mechanisms that lead to PE and summarizes the proteomics research carried out in understanding the pathogenicity of PE, and for identifying the candidate biomarker for diagnosis of the disease.

    ABSTRACT: 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). The vitamin B(12) deficient groups were supplemented with omega 3 fatty acid. An imbalance of maternal micronutrients reduces liver docosahexaenoic acid, increases Δ5 desaturase activity but decreases mRNA levels, decreases Δ6 desaturase activity but not mRNA levels as compared to control. mRNA level of Δ5 desaturase reverts back to the levels of the control group as a result of omega 3 fatty acid supplementation. Our data for the first time indicates that maternal micronutrients differentially alter the activity and expression of fatty acid desaturases in the liver.

    ABSTRACT: 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. Our results show that in preeclamptic women, maternal plasma VEGF and PlGF levels were lower, whereas sFlt-1 levels were higher (P<0.05 for all) than in normotensive women. In contrast, cord plasma VEGF levels were higher (P<0.05) in preeclamptic women, whereas there was no difference in sFlt-1 levels. Plasma DHA levels in both the mother and cord were lower (P<0.05) in the preeclamptic group compared with normotensive women. Maternal plasma sFlt-1 levels were positively (n=23, r=0.415, P=0.039) associated with MDA concentrations in preeclamptic women. Maternal plasma sFlt-1 levels showed a strong negative association with baby weight (n=37, r=-0.547, P=0.001), head circumference (n=37, r=-0.472, P=0.005) and baby chest circumference (n=37, r=-0.375, P=0.032) in the preeclamptic group. Cord plasma sFlt-1 concentrations were negatively associated with cord plasma DHA concentrations (n=28, r=-0.552, P=0.004). This study suggests that dysregulation of angiogenic factors may be associated with maternal oxidative stress. Increased oxidative stress may reduce cord DHA levels and increase sFlt-1 levels, leading to poor birth outcomes in preeclampsia.
