Long-term effects of gestational diabetes mellitus on the pancreas of female mouse offspring. World J Diabetes 2024; 15:758-768. [PMID: 38680692 PMCID: PMC11045410 DOI: 10.4239/wjd.v15.i4.758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 01/29/2024] [Accepted: 03/11/2024] [Indexed: 04/11/2024] Open
Abstract
BACKGROUND Prolonged fetal exposure to hyperglycemia may increase the risk of developing abnormal glucose metabolism and type-2 diabetes during childhood, adolescence, and adulthood; however, the mechanisms by which gestational diabetes mellitus (GDM) predisposes offspring to metabolic disorders remain unknown. AIM To quantify the nerve axons, macrophages, and vasculature in the pancreas from adult offspring born from mouse dams with GDM. METHODS GDM was induced by i.p. administration of streptozotocin (STZ) in ICR mouse dams. At 12 wk old, fasting blood glucose levels were determined in offspring. At 15 wk old, female offspring born from dams with and without GDM were sacrificed and pancreata were processed for immunohistochemistry. We quantified the density of sensory [calcitonin gene-related peptide (CGRP)] and tyrosine hydroxylase (TH) axons, blood vessels (endomucin), and macro-phages (CD68) in the splenic pancreas using confocal microscopy. RESULTS Offspring mice born from STZ-treated dams had similar body weight and blood glucose values compared to offspring born from vehicle-treated dams. However, the density of CGRP+ and TH+ axons, endomucin+ blood vessels, and CD68+ macrophages in the exocrine pancreas was significantly greater in offspring from mothers with GDM vs control offspring. Likewise, the microvasculature in the islets was significantly greater, but not the number of macrophages within the islets of offspring born from dams with GDM compared to control mice. CONCLUSION GDM induces neuronal, vascular, and inflammatory changes in the pancreas of adult progeny, which may partially explain the higher propensity for offspring of mothers with GDM to develop metabolic diseases.

J Nutr 2024; 154:590-599. [PMID: 38159812 DOI: 10.1016/j.tjnut.2023.12.045] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 12/21/2023] [Accepted: 12/27/2023] [Indexed: 01/03/2024] Open
Abstract
BACKGROUND Polyunsaturated fatty acids (PUFAs), especially docosahexaenoic acid (DHA), are critical for proper fetal brain growth and development. Gestational diabetes mellitus (GDM) could affect maternal-fetal fatty acid metabolism. OBJECTIVE This study aimed to explore the effect of GDM and high-fat (HF) diet on the DHA transport signaling pathway in the placenta-brain axis and fatty acid concentrations in the fetal brain. METHODS Insulin receptor antagonist (S961) and HF diet were used to establish an animal model of GDM. Eighty female C57BL/6J mice were randomly divided into control (CON), GDM, HF, and HF+GDM groups. The fatty acid profiles of the maternal liver and fetal brain were analyzed by gas chromatography. In addition, we analyzed the protein amounts of maternal liver fatty acid desaturase (FADS1/3), elongase (ELOVL2/5) and the regulatory factor sterol-regulatory element-binding protein (SREBP)-1c, and the DHA transport signaling pathway (Wnt3/β-catenin/MFSD2a) of the placenta and fetal brain using western blotting. RESULTS GDM promoted the decrease of maternal liver ELOVL2, ELOVL5, and SREBP-1c. Accordingly, we observed a significant decrease in the amount of maternal liver arachidonic acid (AA), DHA, and total n-3 PUFA and n-6 PUFA induced by GDM. GDM also significantly decreased the amount of DHA and n-3 PUFA in the fetal brain. GDM downregulated the Wnt3/β-catenin/MFSD2a signaling pathway, which transfers n-3 PUFA in the placenta and fetal brain. The HF diet increased n-6 PUFA amounts in the maternal liver, correspondingly increasing linoleic acid, gamma-linolenic acid, AA, and total n-6 PUFA in the fetal brain, but decreased DHA amount in the fetal brain. However, HF diet only tended to decrease placental β-catenin and MFSD2a amounts (P = 0.074 and P = 0.098, respectively). CONCLUSIONS Maternal GDM could affect the fatty acid profile of the fetal brain both by downregulating the Wnt3/β-catenin/MFSD2a pathway of the placental-fetal barrier and by affecting maternal fatty acid metabolism.

Abstract
Diabetes mellitus during pregnancy, which can be classified into pregestational diabetes and gestational diabetes, has become much more prevalent worldwide. Maternal diabetes fosters an intrauterine abnormal environment for fetus, which not only influences pregnancy outcomes, but also leads to fetal anomaly and development of diseases in later life, such as metabolic and cardiovascular diseases, neuropsychiatric outcomes, reproduction malformation, and immune dysfunction. The underlying mechanisms are comprehensive and ambiguous, which mainly focus on microbiota, inflammation, reactive oxygen species, cell viability, and epigenetics. This review concluded with the influence of intrauterine hyperglycemia on fetal structure development and organ function on later life and outlined potential mechanisms that underpin the development of diseases in adulthood. Maternal diabetes leaves an effect that continues generations after generations through gametes, thus more attention should be paid to the prevention and treatment of diabetes to rescue the pathological attacks of maternal diabetes from the offspring.

Abstract
Pre-pregnancy obesity and high-fat diet (HFD) during pregnancy and lactation are associated with neurodevelopmental delay in offspring. This study aimed to investigate whether milk fat globule membrane (MFGM) supplementation in obese dams could promote neurodevelopment in offspring. Obese female rats induced by HFD were supplemented with MFGM during pregnancy and lactation. Maternal HFD exposure significantly delayed the maturation of neurological reflexes and inhibited neurogenesis in offspring, which were significantly recovered by maternal MFGM supplementation. Gut microbiota analysis revealed that MFGM supplementation modulated the diversity and composition of gut microbiota in offspring. The abundance of pro-inflammatory bacteria such as Escherichia shigella and Enterococcus were down-regulated, and the abundance of bacteria with anti-inflammatory and anti-obesity functions, such as Akkermansia and Lactobacillus were up-regulated. Furthermore, MFGM alleviated neuroinflammation by decreasing the levels of lipopolysaccharides (LPS) and pro-inflammatory cytokines in the circulation and brain, as well as inhibiting the activation of microglia. Spearman’s correlation analysis suggested that there existed a correlation between gut microbiota and inflammation-related indexes. In conclusion, maternal MFGM supplementation promotes neurodevelopment partly via modulating gut microbiota in offspring.

Abstract
Growing evidence suggests that adverse intrauterine environments could affect the long-term health of offspring. Recent evidence indicates that gestational diabetes mellitus (GDM) is associated with neurocognitive changes in offspring. However, the mechanism remains unclear. Using a GDM mouse model, we collected hippocampi, the structure critical to cognitive processes, for electron microscopy, methylome and transcriptome analyses. Reduced representation bisulfite sequencing (RRBS) and RNA-seq in the GDM fetal hippocampi showed altered methylated modification and differentially expressed genes enriched in common pathways involved in neural synapse organization and signal transmission. We further collected fetal mice brains for metabolome analysis and found that in GDM fetal brains, the metabolites displayed significant changes, in addition to directly inducing cognitive dysfunction, some of which are important to methylation status such as betaine, fumaric acid, L-methionine, succinic acid, 5-methyltetrahydrofolic acid, and S-adenosylmethionine (SAM). These results suggest that GDM affects metabolites in fetal mice brains and further affects hippocampal DNA methylation and gene regulation involved in cognition, which is a potential mechanism for the adverse neurocognitive effects of GDM in offspring.

Abstract
The placenta may play a key role in the activation of inflammation and initiation of insulin resistance (IR) during gestational diabetes mellitus (GDM) pathogenesis. Interleukin (IL)-1β and IL-18, regulated by NLR family pyrin domain containing-3 (NLRP3) inflammasome, are important inflammatory cytokines in the initiation of maternal IR during GDM. However, the mechanism responsible for the regulatory of NLRP3 inflammasome in placenta remains unknown. Hydrogen sulfide (H2S) exerts anti-inflammatory function partially via suppressing the activation of the NLPR3 inflammasome. The present study aimed to investigate the role of NLRP3 inflammasome, H2S synthetase cystathionine-γ-lyase (CSE) and cystathionine-β-synthetase (CBS) in placenta in the pathogenesis of GDM. Clinical placenta samples were collected from pregnant women with GDM (n=16) and healthy pregnant women at term (n=16). Western blot analysis was performed to detect the protein expression levels of NLRP3, cleaved caspase-1, CBS and CSE in the placenta samples. Pearson's correlation analysis was performed to assess the correlation between NLRP3 inflammasome and H2S synthetase. Human placental cells were cultured and treated with different concentrations of NaHS (0, 10, 25 and 50 nmol/l) or L-cysteine (0, 0.25, 0.50 and 1.00 mmol/l). In addition, western blot analysis was performed to detect the protein expression levels of NLRP3 and cleaved caspase-1, while ELISA was performed to measure the production of IL-1β and IL-18 in the culture media. The results demonstrated that the expression levels of NLRP3 and cleaved caspase-1 increased, while the expression levels of CBS and CSE decreased in the placenta samples. In addition, the expression levels of NLRP3 and cleaved caspase-1 were inversely correlated with the expression levels of CBS and CSE. Notably, NaHS and L-cysteine significantly suppressed the expression levels of NLRP3 and cleaved caspase-1, and the production of IL-1 and IL-18 in human placental cells. Taken together, the results of the present study suggest that H2S synthetase deficiency in placenta may contribute to excessive activation of NLRP3 inflammasome in GDM.

Abstract
The current pandemic was caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The quarantine period during corona virus disease 19 (COVID-19) outbreak might affect the quality of life leading thousands of individuals to diminish the daily caloric expenditure and mobility, leading to a sedentary behavior and increase the number of health disorders. Exercising is used as a non-pharmacological treatment in many chronic diseases. Here, we review the molecular mechanisms of physical exercise in COVID-19 pandemic on mental health. We also point links between exercise, mental, and cardiovascular health. The infection caused by SARS-CoV-2 affects host cells binding to angiotensin-converting enzyme-2 (ACE2), which is the receptor for SARS-CoV-2. If there is not enough oxygen supply the lungs and other tissues, such as the heart or brain, are affected. SARS-CoV-2 enhances ACE2 leading to inflammation and neuronal death with possible development of mood disorders, such as depression and anxiety. Physical exercise also enhances the ACE2 expression. Conversely, the activation of ACE2/Ang 1-7/Mas axis by physical exercise induces an antiinflammatory and antifibrotic effect. Physical exercise has beneficial effects on mental health enhancing IGF-1, PI3K, BDNF, ERK, and reducing GSK3β levels. In addition, physical exercise enhances the activity of PGC-1α/ FNDC5/Irisin pathway leading to neuronal survival and the maintenance of a good mental health. Thus, SARS-CoV-2 infection leads to elevation of ACE2 levels through pathological mechanisms that lead to neurological and cardiovascular complications, while the physiological response of ACE2 to physical exercise improves cardiovascular and mental health.

Abstract
Gestational diabetes (GD) is the glucose intolerance that occurs during pregnancy. Mothers who develop diabetes during gestation are at increased risk of developing type 2 diabetes mellitus (T2DM) later in life, and the risk of adverse fetal and neonatal outcomes are also increased as a function of maternal hyperglycemia. Infants who are exposed to fetal hyperglycemia show an increased risk of becoming obese and developing T2DM later in life. Due to the need of new research on this field, and the difficulty of performing studies in human brain, studies using experimental models are necessary to suggest possible ways to avoid or inhibit offspring brain damage or harmful metabolic alterations. Here, it was made a review about the characteristics of the main animal models of GD, and what are the consequences to the brain and behavior of the offspring. In many experimental models, either by pharmacological induction, diet manipulation, or in the use of transgenic animals, glycemic conditions are severe. S961, a selective insulin receptor antagonist, revealed an increased fasting blood glucose level and glucose intolerance during mid-gestation, which returned to basal levels postpartum in mice. GD contributes to offspring neuroinflammation, influences neuronal distribution in central nervous system (CNS), and apoptosis during embryogenesis, which in turn may contribute to changes in behavior and memory in adult life and aging. The usage of animal models to study GD allows to examine extensively the characteristics of this condition, the molecular mechanisms involved and the consequences to the brain and behavior of the offspring.

Abstract
During normal pregnancy, increased insulin resistance acts as an adaptation to enhance materno-foetal nutrient transfer and meet the nutritional needs of the developing foetus, particularly in relation to glucose requirements. However, about 1 in 6 pregnancies worldwide is affected by the inability of the mother's metabolism to maintain normoglycaemia, with the combination of insulin resistance and insufficient insulin secretion resulting in gestational diabetes mellitus (GDM). A growing body of epidemiologic work demonstrates long-term implications for adverse offspring health resulting from exposure to GDM in utero. The effect of GDM on offspring obesity and cardiometabolic health may be partly influenced by maternal obesity; this suggests that improving glucose and weight control during early pregnancy, or better still before conception, has the potential to lessen the risk to the offspring. The consequences of GDM for microbiome modification in the offspring and the impact upon offspring immune dysregulation are actively developing research areas. Some studies have suggested that GDM impacts offspring neurodevelopmental and cognitive outcomes; confirmatory studies will need to separate the effect of GDM exposure from the complex interplay of social and environmental factors. Animal and human studies have demonstrated the role of epigenetic modifications in underpinning the predisposition to adverse health in offspring exposed to suboptimal hyperglycaemic in utero environment. To date, several epigenome-wide association studies in human have extended our knowledge on linking maternal diabetes-related DNA methylation marks with childhood adiposity-related outcomes. Identification of such epigenetic marks can help guide future research to develop candidate diagnostic biomarkers and preventive or therapeutic strategies. Longer-term interventions and longitudinal studies will be needed to better understand the causality, underlying mechanisms, or impact of GDM treatments to optimize the health of future generations.

Abstract
PURPOSE/AIM Zika virus (ZIKV) infection during the pregnancy period is related to microcephaly and neurobehavioral disorders at birth, while prenatal exercise is supposed to provide neuroprotection in newborns pups. The aim of this study was to investigate the neurological consequences of exercise during prenatal ZIKV exposure to mice pups. MATERIAL AND METHODS Twelve weeks female mice were randomly assigned into three groups: Control group, intraperitoneally injected with saline (Control); untrained group, intraperitoneally injected with ZIKV (ZIKV); and trained group, intraperitoneally injected with ZIKV (ZIKV/swim). There was one familiarization week prior to the beginning of the swimming training. Dams swam for 60 min/session, 5 days/week, during 4 weeks. Mating occurred between the fifth and seventh day of the first week of the swimming training. ZIKV 106 plaque-forming units/100 µl (106 PFUs/100 µl) or an equal volume of saline was intraperitoneally injected in the pregnant mice at embryonic day 10.5. Pup's body mass and brain weight were measured at postnatal day 1 (P1). Behavioral tests were performed from P30 to P35. Thereafter, hippocampal levels of syntaxin-1, GFAP, IBA-1, and BDNF were measured. RESULTS Exercise during prenatal ZIKV exposure prevented brain atrophy, development of depression, anxiety, and disruption of social behavior. Exercise during prenatal ZIKV exposure inhibited the overexpression of microglia (IBA-1) and astrocytes (GFAP), with reduction of BDNF levels in the hippocampi of female and male mice pups. No significant changes were seen in syntaxin-1 levels. CONCLUSION Our findings reveal beneficial effects of exercise during pregnancy exposure to ZIKV in mice pups.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) raises the risk of high blood pressure and may cause a series of life-threatening complications in pregnant women. Screening and management of GDM and gestational hypertension (GH) in pregnancy helps to control and reduce these risks and prevent adverse effects on mothers and their fetuses. Currently, the majority criteria used for screening of diabetes mellitus is oral glucose tolerance tests, and blood pressure test is usually used for the screening and diagnosis of hypertension. However, these criteria might not anticipate or detect all GDM or GH cases. Therefore, new specific predictive and diagnostic tools should be evaluated for this population. This study selected three biomarkers of osteoprotegerin (OPG), interleukin (IL) and hepatocyte growth factor (HGF) for GDM and GH predication and diagnosis.
AIM To explore the feasibility of changes in placental and serum OPG, IL and HGF as tools for prediction and diagnosis of diabetes and hypertension in pregnant women.
METHODS From January 2018 to January 2019, 44 pregnant women with GDM and GH were selected as an observation group, and 44 healthy pregnant women were selected as a control group in the same period. Serum OPG, IL and HGF were compared between the two groups.
RESULTS The levels of OPG and HGF in the observation group were lower than in the control group, and the level of IL-1β was higher in the observation group than in the control group (all P < 0.05). Furthermore, OPG and HGF were negatively associated with gestational diabetes and gestational hypertension, while IL-1β was positively associated with GDM complicated with GH (all P < 0.05).
CONCLUSION The evaluation of serum OPG, HGF and IL-1β levels in patients with coexistent gestational diabetes complicated with hypertension can predict the degree of disease and play an important role in the follow-up treatment and prognosis prediction.

Abstract
Alzheimer's disease (AD) and type 2 diabetes (T2D) major feature is insulin resistance. Brain and peripheral insulin resistance lead to hyperglycemia, which contributes to the development of T2D-linked comorbidities, such as obesity and dyslipidemia. Individuals with hyperglycemia in AD present with neuronal loss, formation of plaques and tangles and reduced neurogenesis. Inflammation seems to play an essential role in the development of insulin resistance in AD and T2D. We conducted a literature review about the links between AD and T2D. Alterations in glucose metabolism result from changes in the expression of the insulin receptor substrates 1 and 2 (IRS-1 and IRS-2), and seem to be mediated by several inflammatory pathways being present in both pathologies. Although there are some similarities in the insulin resistance of AD and T2D, brain and peripheral insulin resistance also have their discrete features. Failure to activate IRS-1 is the hallmark of AD, while inhibition of IRS-2 is the main feature in T2D. Inflammation mediates the alterations in glucose metabolism in AD and T2D. Targeting inflammation and insulin receptors may be a successful strategy to prevent and ameliorate T2D and AD symptoms.

High-intensity resistance training induces changes in cognitive function, but not in locomotor activity or anxious behavior in rats induced to type 2 diabetes. Physiol Behav 2020; 223:112998. [PMID: 32505787 DOI: 10.1016/j.physbeh.2020.112998] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2019] [Revised: 03/12/2020] [Accepted: 06/01/2020] [Indexed: 10/24/2022]
Abstract
Type 2 diabetes (T2D) is a metabolic disorder that can lead to cognitive decline through impairment of insulin signaling. Resistance training, a type of physical exercise, is a non-pharmacological approach used to improve insulin resistance in T2D. The aim of our study was to evaluate the effects of high-intensity resistance training (HIRT) over cognitive function, locomotor activity, and anxious behavior in rats induced to T2D. Thirty young adult male wistar rats were distributed into 3 groups (n = 10): Control; dexamethasone (D); and dexamethasone + exercise (DE), that performed the HIRT during 4 weeks. Blood glucose, water intake, and total body fat were measured. Locomotor activity, and anxious behavior where evaluated through the open field task. Cognitive function was assessed through the novel object recognition task. Insulin resistance and neuronal death were evaluated through western blot analysis. Rats induced to T2D had higher blood glucose levels, and consumed more water when compared to control group, but DE had better blood glucose levels than D. Total body fat was reduced in DE compared to D. Locomotor activity, and anxious behavior were not significantly altered. T2D rats which performed HIRT maintained cognitive function, while those induced to T2D that did not exercise developed cognitive decline. DE group showed a reduction in the inhibition of the activation of hippocampal IRS-1 and higher expression of GSk3β phosphorylated in serine compared to D group, revealing insulin signaling impairment, and neuronal death were identified in the hippocampus of D group. Lifestyle intervention through the regular practice of HIRT plays a fundamental role in the treatment of T2D preventing cognitive decline.
