Characterization of the MG828507 lncRNA Located Upstream of the FLT1 Gene as an Etiology for Pre-Eclampsia.

ABSTRACT:

Background

FLT1 is one of the significantly overexpressed genes found in a pre-eclamptic placenta and is involved with the etiology of this disease.

Methods

We conducted genome-wide expression profiling by RNA-seq of placentas from women with pre-eclampsia and those with normotensive pregnancy.

Results

We identified a lncRNA gene, MG828507, located ~80 kb upstream of the FLT1 gene in a head-to-head orientation, which was overexpressed in the pre-eclamptic placenta. MG828507 and FLT1 are located within the same topologically associated domain in the genome. The MG828507 mRNA level correlated with that of the FLT1 in placentas from pre-eclamptic women as well as in samples from uncomplicated pregnancies. However, neither the overexpression nor knockdown of MG828507 affected the expression of FLT1. Analysis of pre-eclampsia-linking genetic variants at this locus suggested that the placental genotype of one variant was associated with the expression of MG828507. The MG828507 transcript level was not found to be associated with maternal blood pressure, but showed a relationship with birth and placental weights, suggesting that this lncRNA might be one of the pivotal placental factors in pre-eclampsia.

Conclusion

Further characterization of the MG828507 gene may elucidate the etiological roles of the MG828507 and FLT1 genes in pre-eclampsia in a genomic context.

Project description:BackgroundPre-eclampsia is the most common complication occurring during pregnancy. In the majority of cases, it is concurrent with other pathologies in a comorbid manner (frequent co-occurrences in patients), such as diabetes mellitus, gestational diabetes and obesity. Providing bronchial asthma, pulmonary tuberculosis, certain neurodegenerative diseases and cancers as examples, we have shown previously that pairs of inversely comorbid pathologies (rare co-occurrences in patients) are more closely related to each other at the molecular genetic level compared with randomly generated pairs of diseases. Data in the literature concerning the causes of pre-eclampsia are abundant. However, the key mechanisms triggering this disease that are initiated by other pathological processes are thus far unknown. The aim of this work was to analyse the characteristic features of genetic networks that describe interactions between comorbid diseases, using pre-eclampsia as a case in point.ResultsThe use of ANDSystem, Pathway Studio and STRING computer tools based on text-mining and database-mining approaches allowed us to reconstruct associative networks, representing molecular genetic interactions between genes, associated concurrently with comorbid disease pairs, including pre-eclampsia, diabetes mellitus, gestational diabetes and obesity. It was found that these associative networks statistically differed in the number of genes and interactions between them from those built for randomly chosen pairs of diseases. The associative network connecting all four diseases was composed of 16 genes (PLAT, ADIPOQ, ADRB3, LEPR, HP, TGFB1, TNFA, INS, CRP, CSRP1, IGFBP1, MBL2, ACE, ESR1, SHBG, ADA). Such an analysis allowed us to reveal differential gene risk factors for these diseases, and to propose certain, most probable, theoretical mechanisms of pre-eclampsia development in pregnant women. The mechanisms may include the following pathways: [TGFB1 or TNFA]-[IL1B]-[pre-eclampsia]; [TNFA or INS]-[NOS3]-[pre-eclampsia]; [INS]-[HSPA4 or CLU]-[pre-eclampsia]; [ACE]-[MTHFR]-[pre-eclampsia].ConclusionsFor pre-eclampsia, diabetes mellitus, gestational diabetes and obesity, we showed that the size and connectivity of the associative molecular genetic networks, which describe interactions between comorbid diseases, statistically exceeded the size and connectivity of those built for randomly chosen pairs of diseases. Recently, we have shown a similar result for inversely comorbid diseases. This suggests that comorbid and inversely comorbid diseases have common features concerning structural organization of associative molecular genetic networks.

Project description:BackgroundAn evidence-based strategy exists to reduce maternal morbidity and mortality associated with severe pre-eclampsia/eclampsia (PE/E), but it may be difficult to implement in low-resource settings. This study examines whether facilities that provide emergency obstetric and newborn care (EmONC) in Afghanistan have the capacity to manage severe PE/E cases.MethodsA further analysis was conducted of the 2009-10 Afghanistan EmONC Needs Assessment. Assessors observed equipment and supplies available, and services provided at 78 of the 127 facilities offering comprehensive EmONC services and interviewed 224 providers. The providers also completed a written case scenario on severe PE/E. Descriptive statistics were used to summarize facility and provider characteristics. Student t-test, one-way ANOVA, and chi-square tests were performed to determine whether there were significant differences between facility types, doctors and midwives, and trained and untrained providers.ResultsThe median number of severe PE/E cases in the past year was just 5 (range 0-42) at comprehensive health centers (CHCs) and district hospitals, compared with 44 (range 0-130) at provincial hospitals and 108 (range 32-540) at regional and specialized hospitals (p < 0.001). Most facilities had the drugs and supplies needed to treat severe PE/E, including the preferred anticonvulsant, magnesium sulfate (MgSO4). One-third of the smallest facilities and half of larger facilities reported administering a second-line drug, diazepam, in some cases. In the case scenario, 96% of doctors and 89% of midwives recognized that MgSO4 should be used to manage severe PE/E, but 42% of doctors and 58% of midwives also thought diazepam had a role to play. Providers who were trained on the use of MgSO4 scored significantly higher than untrained providers on six of 20 items in the case scenario. Providers at larger facilities significantly outscored those at smaller facilities on five items. There was a significant difference between doctors and midwives on only one item: continued use of anti-hypertensives after convulsions are controlled.ConclusionsDrugs and supplies needed to treat severe PE/E are widely available at EmONC facilities in Afghanistan, but providers lack knowledge in some areas, especially concerning the use of MgSO4 and diazepam. Providers who have specialized training or work at larger facilities are better at managing cases of severe PE/E. The findings suggest a need to clarify service delivery guidelines, offer refresher training, and reinforce best practices with supervision and reinforcement.

Project description:BackgroundSub-Saharan Africa has the highest maternal mortality ratio at 500 deaths per 100,000 live births. In Mozambique maternal mortality is estimated at 249-480 per 100,000 live births and eclampsia is the third leading cause of death. The objective of this study was to describe the community understanding of pre-eclampsia and eclampsia, as a crucial step to improve maternal and perinatal health in southern Mozambique.MethodsThis qualitative study was conducted in Maputo and Gaza Provinces of southern Mozambique. Twenty focus groups were convened with pregnant women, partners and husbands, matrons and traditional birth attendants, and mothers and mothers-in-law. In addition, ten interviews were conducted with traditional healers, matrons, and a traditional birth attendant. All discussions were audio-recorded, translated from local language (Changana) to Portuguese and transcribed verbatim prior to analysis with QSR NVivo 10. A thematic analysis approach was taken.ResultsThe conditions of "pre-eclampsia" and "eclampsia" were not known in these communities; however, participants were familiar with hypertension and seizures in pregnancy. Terms linked with the biomedical concept of pre-eclampsia were high blood pressure, fainting disease and illness of the heart, whereas illness of the moon, snake illness, falling disease, childhood illness, illness of scaresand epilepsy were used to characterizeeclampsia. The causes of hypertension in pregnancy were thought to include mistreatment by in-laws, marital problems, and excessive worrying. Seizures in pregnancy were believed to be caused by a snake living inside the woman's body. Warning signs thought to be common to both conditions were headache, chest pain, weakness, dizziness, fainting, sweating, and swollen feet.ConclusionLocal beliefs in southern Mozambique, regarding the causes, presentation, outcomes and treatment of pre-eclampsia and eclampsia were not aligned with the biomedical perspective. The community was often unaware of the link between hypertension and seizures in pregnancy. The numerous widespread myths and misconceptions concerning pre-eclampsia and eclampsiamay induceinappropriatetreatment-seeking and demonstrate a need for increased community education regarding pregnancy and associated complications.Trial registrationNCT01911494.
