[PMID: 34768025 DOI: 10.1016/j.plefa.2021.102364] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Revised: 10/01/2021] [Accepted: 10/27/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND Preeclampsia is a pregnancy disorder characterized with abnormal placental angiogenesis. Vitamin D and long chain polyunsaturated fatty acids (LCPUFA) play a crucial role in pregnancy and are required for normal placental and fetal growth and development. This study reports the effect of maternal vitamin D on LCPUFA levels in the mother and offspring brain fatty acid levels and angiogenic markers in a rat model of preeclampsia. METHODS Female rats were divided into four groups from pre-pregnancy to pregnancy, viz Control; Preeclampsia (PE); Vitamin D deficient with PE (VDD-PE) and Vitamin D supplemented with PE (VDS-PE). Preeclampsia was induced by administering l-nitroarginine methyl ester (L-NAME) at the dose of 50 mg/kg body weight/day from day 14 to day 19 of gestation. Dams were sacrificed at d20 of gestation to collect dam blood, placenta and pup brain. LCPUFA levels from dam plasma, erythrocytes and placenta and its transcription factor peroxisome proliferator activated receptor gamma (PPAR-g) from placenta were estimated. Pup brain LCPUFA levels, angiogenic factors vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) and transcription factor hypoxia inducible factor (Hif-1α) and PPAR-g were also estimated. RESULTS Maternal vitamin D status influences fatty acid levels. Placental PPAR-g levels were lower in the VDD-PE group as compared to the VDS-PE groups (p < 0.01). In the offspring brain, both PE and VDD-PE group showed lower levels of DHA (p < 0.05 for both) while saturated fatty acids (SFA) levels in the VDD-PE group were higher as compared to the control group (p < 0.05). VDD-PE group also showed lower levels of PlGF and PPAR-g (p < 0.01 and p < 0.05, respectively) in the pup brain while vitamin D supplementation demonstrated levels similar to control. CONCLUSION This study for the first time demonstrates that maternal vitamin D status influences LCPUFA metabolism and angiogenesis in the offspring brain.

Abstract
OBJECTIVES To assess whether serum concentrations of saturated (SFAs), polyunsaturated (PUFAs), and monounsaturated (MUFAs) fatty acids are associated with changes in blood pressure (BP) throughout pregnancy. STUDY DESIGN Prospective cohort. MAIN OUTCOME MEASURES Longitudinal measurements of systolic (SBP) and diastolic (DBP) BP. METHODS Two hundred twenty-three healthy pregnant women were recruited in a public health center in Rio de Janeiro, Brazil between 2009 and 2011. Fasting blood samples and BP measurements were obtained at the 1st (5th-13th weeks), 2nd (20th-26th) and 3rd trimester (30th-36th). Crude and adjusted (maternal age, education, energy intake, gestational body weight change, leptin concentrations, early pre-pregnancy BMI, leisure time physical activity prior to pregnancy and linear and quadratic gestational weeks) longitudinal linear mixed-effects models were employed. RESULTS SBP and DBP decreased from the 1st to the 2nd trimester and slightly increased from the 2nd to the 3rd trimester (P < 0.001). In the adjusted model (ß and 95% CI), total SFAs [0.005 (0.001-0.008); P = 0.008], total MUFAs [0.005 (0.001-0.009); P = 0.019] and total n-6 PUFAs [0.005 (0.001-0.009); P = 0.025] were positively associated with SBP throughout pregnancy. CONCLUSIONS Maternal serum concentrations of total SFAs, MUFAs and n-6 PUFAs were positively associated with BP levels in normotensive pregnant women.

Abstract
Pulmonary hypertension (PH) and right ventricular hypertrophy (RVH) affect 16-25% of premature infants with bronchopulmonary dysplasia (BPD), contributing significantly to perinatal morbidity and mortality. Omega-3 polyunsaturated fatty acids (PUFA ω-3) can improve vascular remodeling, angiogenesis, and inflammation under pathophysiological conditions. However, the effects of PUFA ω-3 supplementation in BPD-associated PH are unknown. The present study aimed to evaluate the effects of PUFA ω-3 on pulmonary vascular remodeling, angiogenesis, and inflammatory response in a hyperoxia-induced rat model of PH. From embryonic day 15, pregnant Sprague-Dawley rats were supplemented daily with PUFA ω-3, PUFA ω-6, or normal saline (0.2 ml/day). After birth, pups were pooled, assigned as 12 per litter, randomly assigned to either air or continuous oxygen exposure (fraction of inspired oxygen = 85%) for 20 days, and then euthanized for pulmonary hemodynamic and morphometric analysis. We found that PUFA ω-3 supplementation improved survival, decreased right ventricular systolic pressure and RVH caused by hyperoxia, and significantly improved alveolarization, vascular remodeling, and vascular density. PUFA ω-3 supplementation produced a higher level of total ω-3 in lung tissue and breast milk and was found to reverse the reduced levels of VEGFA, VEGF receptor 2, angiopoietin-1 (ANGPT1), endothelial TEK tyrosine kinase, endothelial nitric oxide synthase, and nitric oxide concentrations in lung tissue and the increased ANGPT2 levels in hyperoxia-exposed rats. The beneficial effects of PUFA ω-3 in improving lung injuries were also associated with an inhibition of leukocyte infiltration and reduced expression of the proinflammatory cytokines IL-1β, IL-6, and TNF-α. These data indicate that maternal PUFA ω-3 supplementation strategies could effectively protect against infant PH induced by hyperoxia.

[PMID: 26674001 PMCID: PMC4661600 DOI: 10.1016/j.bbacli.2015.06.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/10/2015] [Revised: 06/11/2015] [Accepted: 06/16/2015] [Indexed: 01/23/2023]
Abstract
Background Long chain polyunsaturated fatty acids (LCPUFAs) are biologically active fatty acids which regulate placental angiogenesis, inflammation, and oxidative stress. Abnormalities in these aspects have been associated with preeclampsia (PE). Further, placenta has a heterogeneous structure with differential vascularization across different regions. We therefore hypothesize that the distribution of fatty acids in various regions of the placenta is altered in PE leading to poor fetal outcome. Methods In this cross-sectional study we recruited 69 normotensive control (NC) and 44 women with PE. PE women were further classified as those delivered preterm (PTPE, n = 24) and at term (TPE, n = 20). Fatty acid levels were analyzed from placental samples from four different regions (CF—central fetal, PF—peripheral fetal, CM—central maternal and PM—peripheral maternal). Results In the NC placenta, AA levels were lower (p < 0.05) in CM as compared with CF region. However, such differences were not seen in the TPE and PTPE. In contrast, the DHA levels varied between regions only in the PTPE placenta. Between groups, DHA levels were lower (p < 0.05 for both) in the CM and CF regions of the PTPE as compared with NC. The levels of DHA in TPE placenta were similar to NC. AA levels were lower (p < 0.05 for both) in CF region of TPE and PF region of PTPE placenta than NC. Conclusions There is differential pattern of LCPUFA distribution across various regions of the NC, TPE and PTPE placenta. This may have implications for placental growth and development as well as transfer of LCPUFA to the fetus. There are regional differences in fatty acid levels in normal placenta. Regional fatty acid distribution is further affected in preeclampsia. Preterm preeclampsia placenta is more affected than term preeclampsia and control. DHA of peripheral fetal region positively associated with baby weight in preeclampsia.
