Effect of L-Ergothioneine on the metabolic plasma profile of the RUPP rat model of pre-eclampsia.

ABSTRACT:

Introduction

Pre-eclampsia is a major cause of maternal and fetal mortality and morbidity worldwide. Its pathophysiology remains unclear, but mitochondrial dysfunction and oxidative stress have been implicated. L-Ergothioneine is a naturally occurring, water-soluble betaine, that has demonstrated antioxidant properties. Using the reduced uterine perfusion pressure (RUPP) rat model of pre-eclampsia, this study aimed to define the plasma metabolic profile following treatment with L-Ergothioneine.

Methods

The effect of L-Ergothioneine (ET) treatment was explored using in vivo treatment in rats: Sham control (SC, n = 5), RUPP control (RC, n = 5), Sham +ET (ST, n = 5), RUPP +ET (RT, n = 5). Differential expression of plasma metabolites were obtained using untargeted liquid chromatography coupled to mass spectrometry. Statistical analysis was performed on normalised data comparing RC to SC, RT to RC, and RT to ST. Metabolites significantly altered (FDR < 0.05) were identified through database search.

Results

We report significantly lower levels of L-palmitoylcarnitine in RC compared to SC, a fatty acyl substrate involved in beta-oxidation in the mitochondria. We report that a metabolite that has been associated with oxidative stress (Glutamylcysteine) was detected at significantly higher levels in RT vs RC and RT vs ST. Five metabolites associated with inflammation were significantly lower in RT vs RC and three metabolites in RT vs ST, demonstrating the anti-inflammatory effects of ET in the RUPP rat model of pre-eclampsia.

Conclusions

L-Ergothioneine may help preserve mitochondrial function by increasing antioxidant levels, and reducing inflammatory responses associated with pre-eclampsia. This study shows the potential of L-Ergothioneine as a treatment for pre-eclampsia.

Project description:BACKGROUND:In Nigeria, hypertensive disorders have become the leading cause of facility-based maternal mortality. Many factors influence pregnant women's health-seeking behaviors and perceptions around the importance of antenatal care. This qualitative study describes the care-seeking pathways of Nigerian women who suffer from pre-eclampsia and eclampsia. It identifies the influences - barriers and enablers - that affect their decision making, and proposes solutions articulated by women themselves to overcome the obstacles they face. Informing this study is the health belief model, a cognitive value-expectancy theory that provides a framework for exploring perceptions and understanding women's narratives around pre-eclampsia and eclampsia-related care seeking. METHODS:This study adopted a qualitative design that enables fully capturing the narratives of women who experienced pre-eclampsia and eclampsia during their pregnancy. In-depth interviews were conducted with 42 women aged 17-48 years over five months in 2015 from Bauchi, Cross River, Ebonyi, Katsina, Kogi, Ondo and Sokoto states to ensure representation from each geo-political zone in Nigeria. These qualitative data were analyzed through coding and memo-writing, using NVivo 11 software. RESULTS:We found that many of the beliefs, attitudes, knowledge and behaviors of women are consistent across the country, with some variation between the north and south. In Nigeria, women's perceived susceptibility and threat of health complications during pregnancy and childbirth, including pre-eclampsia and eclampsia, influence care-seeking behaviors. Moderating influences include acquisition of knowledge of causes and signs of pre-eclampsia, the quality of patient-provider antenatal care interactions, and supportive discussions and care seeking-enabling decisions with families and communities. These cues to action mitigate perceived mobility, financial, mistrust, and contextual barriers to seeking timely care and promote the benefits of maternal and newborn survival and greater confidence in and access to the health system. CONCLUSIONS:The health belief model reveals intersectional effects of childbearing norms, socio-cultural beliefs and trust in the health system and elucidates opportunities to intervene and improve access to quality and respectful care throughout a woman's pregnancy and childbirth. Across Nigerian settings, it is critical to enhance context-adapted community awareness programs and interventions to promote birth preparedness and social support.

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.
