A dimerization domain in the middle region acts as a hub for protein–protein interaction, while a non-canonical RNA-binding site is placed towards the C-terminus. The singular organization of structural domains present in GEMIN5 enables this protein to perform multiple functions through its ability to interact with distinct partners, both RNAs and proteins. This protein exerts a different role in translation regulation depending on its physiological state, such that while GEMIN5 down-regulates global RNA translation, the C-terminal half of the protein promotes translation of its mRNA. Additionally, GEMIN5 is responsible for the preferential partitioning of mRNAs into polysomes. Besides selective translation, GEMIN5 forms part of distinct ribonucleoprotein complexes, reflecting the dynamic organization of macromolecular complexes in response to internal and external signals. In accordance with its contribution to fundamental cellular processes, recent reports described clinical loss of function mutants suggesting that GEMIN5 deficiency is detrimental to cell growth and survival. Remarkably, patients carrying GEMIN5 biallelic variants suffer from neurodevelopmental delay, hypotonia, and cerebellar ataxia. Molecular analyses of individual variants, which are defective in protein dimerization, display decreased levels of ribosome association, reinforcing the involvement of the protein in translation regulation. Importantly, the number of clinical variants and the phenotypic spectrum associated with GEMIN5 disorders is increasing as the knowledge of the protein functions and the pathways linked to its activity augments. Here we discuss relevant advances concerning the functional and structural features of GEMIN5 and its separate domains in RNA-binding, protein interactome, and translation regulation, and how these data can help to understand the involvement of protein malfunction in clinical variants found in patients developing neurodevelopmental disorders.展开更多

Alt...Mitochondrial dysfunction has emerged as a critical factor in the etiology of various neurodevelopmental disorders, including autism spectrum disorders, attention-deficit/hyperactivity disorder, and Rett syndrome. Although these conditions differ in clinical presentation, they share fundamental pathological features that may stem from abnormal mitochondrial dynamics and impaired autophagic clearance, which contribute to redox imbalance and oxidative stress in neurons. This review aimed to elucidate the relationship between mitochondrial dynamics dysfunction and neurodevelopmental disorders. Mitochondria are highly dynamic organelles that undergo continuous fusion and fission to meet the substantial energy demands of neural cells. Dysregulation of these processes, as observed in certain neurodevelopmental disorders, causes accumulation of damaged mitochondria, exacerbating oxidative damage and impairing neuronal function. The phosphatase and tensin homolog-induced putative kinase 1/E3 ubiquitin-protein ligase pathway is crucial for mitophagy, the process of selectively removing malfunctioning mitochondria. Mutations in genes encoding mitochondrial fusion proteins have been identified in autism spectrum disorders, linking disruptions in the fusion-fission equilibrium to neurodevelopmental impairments. Additionally, animal models of Rett syndrome have shown pronounced defects in mitophagy, reinforcing the notion that mitochondrial quality control is indispensable for neuronal health. Clinical studies have highlighted the importance of mitochondrial disturbances in neurodevelopmental disorders. In autism spectrum disorders, elevated oxidative stress markers and mitochondrial DNA deletions indicate compromised mitochondrial function. Attention-deficit/hyperactivity disorder has also been associated with cognitive deficits linked to mitochondrial dysfunction and oxidative stress. Moreover, induced pluripotent stem cell models derived from patients with Rett syndrome have shown impaired mitochondrial dynamics and heightened vulnerability to oxidative injury, suggesting the role of defective mitochondrial homeostasis in these disorders. From a translational standpoint, multiple therapeutic approaches targeting mitochondrial pathways show promise. Interventions aimed at preserving normal fusion-fission cycles or enhancing mitophagy can reduce oxidative damage by limiting the accumulation of defective mitochondria. Pharmacological modulation of mitochondrial permeability and upregulation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha, an essential regulator of mitochondrial biogenesis, may also ameliorate cellular energy deficits. Identifying early biomarkers of mitochondrial impairment is crucial for precision medicine, since it can help clinicians tailor interventions to individual patient profiles and improve prognoses. Furthermore, integrating mitochondria-focused strategies with established therapies, such as antioxidants or behavioral interventions, may enhance treatment efficacy and yield better clinical outcomes. Leveraging these pathways could open avenues for regenerative strategies, given the influence of mitochondria on neuronal repair and plasticity. In conclusion, this review indicates mitochondrial homeostasis as a unifying therapeutic axis within neurodevelopmental pathophysiology. Disruptions in mitochondrial dynamics and autophagic clearance converge on oxidative stress, and researchers should prioritize validating these interventions in clinical settings to advance precision medicine and enhance outcomes for individuals affected by neurodevelopmental disorders.展开更多

Myelomeningocele is considered the most common malformation and the most common we saw in our community, with its morbidity problems seen commonly in the postoperative period. ASQ-3<sup>TM</sup> Scores are the ages and stages questionnaire, third edition, and represent a tool to assess the development progress, especially in toddlers. Objectives: Evaluation of neurodevelopmental outcome among Sudanese toddlers with spinal dysraphism after surgical closure with or without a VP shunt using ASQ-3<sup>TM</sup> Scores. Methodology: This is a retrospective hospital-based study of 84 patients who underwent myelomeningocele repair at the National Center for Neurological Sciences (NCNS) during the period from 2017 up to 2019. Data were collected through a constructed questionnaire, including ASQ-3<sup>TM</sup> Scores. Data were processed and analyzed using the Statistical Package for Social Science (SPSS) computer program. Version 25. Results: 84 patients were included in this study;all patients were diagnosed with spinal dysraphism. Out of them, 51 (60.7%) were 2 years old, 33 (39.3%) were 3 years old, 45 (53.6%) were male, 45 (53.6%) of patients mothers attended ANC irregularly, and 54 (64.3%) their mothers didn’t receive folate supplements. 44 (52.3%) of patients underwent MMC repair only, while 40 (47.7%) underwent MMC repair and VP shunt. The commonest postoperative complication was infection, reported in 12 (14.3%) of patients, followed by VP shunt revision in 9 (10.7%) of patients. Neurological assessment showed that the majority of patients need further assessment with a professional, 57 (67.9%) of children don’t walk, run, or climb like other toddlers as their parent’s state;also, half of patients (42, 50%) had medical problems, and 27 (32.1%) of their parent’s state that they do not talk like other toddlers their age. There was a statistically significant association between post-operative complications and communication development, problem-solving development, and personal social development (P value = 0.05), and a statistically significant association was found between age at repair and neurological development (P value = 0.05). Conclusion: The majority of patients had motor deficiency (particularly gross motor) and poor personal and social skills. Age at repair and postoperative complications significantly influenced the neurological development.展开更多

Methods: Among 2465 deliveries between 2013 and 2019, 109 cases of FGR were reviewed retrospectively for causes, indications for pregnancy termination, perinatal death, overall neonatal outcomes, and long-term prognosis. Results: Excluding FGR due to congenital anomalies (n = 17), the mortality rate was 3.3% (3/92). One neonate delivered at 23 weeks developed cerebral palsy (1.1%). Retinopathy of prematurity occurred in four neonates (4.3%). Neurodevelopmental disorders were present in six neonates (6.5%), all of whom were delivered at 32 - 38 weeks. Significantly lower gestational age at delivery, lower birth weight, and higher umbilical artery resistance indices were observed in neonates with neurodevelopmental disorders. Conclusions: Intact survival before 27 weeks of gestation at delivery with FGR is uncommon. Neurodevelopmental disorders may still develop after delivery at 32 - 38 weeks;consideration should be given to the timing of delivery usingfetal ductus venosus Doppler waveforms measurements to reduce neurodevelopmental disorders.展开更多

Common major neurodevelopmental disorders include autism and autism spectrum disorders （ASDs）, fragile X syndrome （FXS）, Down syndrome （DS）, and Rett syndrome （RTT）. They can be collectively described as disorders in which the plasticity of the brain has been severely impaired. The concept of plasticity refers to the brain＇s ability to adapt to and process new information and react accordingly, and it can be classified into three categories： a） molecular plasticity, whenever specific receptors, ion channels, enzymes,展开更多

In autism spectrum disorders, elevated oxidative stress markers and mitochondrial DNA deletions indicate compromised mitochondrial function. Attention-deficit/hyperactivity disorder has also been associated with cognitive deficits linked to mitochondrial dysfunction and oxidative stress. Moreover, induced pluripotent stem cell models derived from patients with Rett syndrome have shown impaired mitochondrial dynamics and heightened vulnerability to oxidative injury, suggesting the role of defective mitochondrial homeostasis in these disorders. From a translational standpoint, multiple therapeutic approaches targeting mitochondrial pathways show promise. Interventions aimed at preserving normal fusion-fission cycles or enhancing mitophagy can reduce oxidative damage by limiting the accumulation of defective mitochondria. Pharmacological modulation of mitochondrial permeability and upregulation of peroxisome proliferator-activated receptor gamma coactivator 1-alpha, an essential regulator of mitochondrial biogenesis, may also ameliorate cellular energy deficits. Identifying early biomarkers of mitochondrial impairment is crucial for precision medicine, since it can help clinicians tailor interventions to individual patient profiles and improve prognoses. Furthermore, integrating mitochondria-focused strategies with established therapies, such as antioxidants or behavioral interventions, may enhance treatment efficacy and yield better clinical outcomes. Leveraging these pathways could open avenues for regenerative strategies, given the influence of mitochondria on neuronal repair and plasticity. In conclusion, this review indicates mitochondrial homeostasis as a unifying therapeutic axis within neurodevelopmental pathophysiology. Disruptions in mitochondrial dynamics and autophagic clearance converge on oxidative stress, and researchers should prioritize validating these interventions in clinical settings to advance precision medicine and enhance outcomes for individuals affected by neurodevelopmental disorders.

文摘Maternal health during pregnancy has a direct impact on the risk and severity of neurodevelopmental disorders(NDDs)in the offspring,especially in the case of drug exposure.However,little progress has been made to assess the risk of drug exposure during pregnancy due to ethical constraints and drug use factors.We collected and manually curated sub-pathways and pathways(sub-/pathways)and drug information to propose an analytical framework for predicting drug candidates.This framework linked sub-/pathway activity and drug response scores derived from gene transcription data and was applied to human fetal brain development and six NDDs.Further,specific and pleiotropic sub-/pathways/drugs were identified using entropy,and sex bias was analyzed in conjunction with logistic regression and random forest models.We identified 19 disorder-associated and 256 regionally pleiotropic and specific candidate drugs that targeted risk sub-/pathways in NDDs,showing temporal or spatial changes across fetal development.Moreover,5443 differential drug-sub-/pathways exhibited sex-biased differences after filling in the gender labels.A user-friendly NDDP visualization website(https://ndd-lab.shinyapps.io/NDDP)was developed to allow researchers and clinicians to access and retrieve data easily.Our framework overcame data gaps and identified numerous pleiotropic and specific candidates across six disorders and fetal developmental trajectories.This could significantly contribute to drug discovery during pregnancy and can be applied to a wide range of traits.
文摘Background: Spinal dysraphism represents a wide spectrum of congenital abnormalities of the spine. Myelomeningocele is considered the most common malformation and the most common we saw in our community, with its morbidity problems seen commonly in the postoperative period. ASQ-3<sup>TM</sup> Scores are the ages and stages questionnaire, third edition, and represent a tool to assess the development progress, especially in toddlers. Objectives: Evaluation of neurodevelopmental outcome among Sudanese toddlers with spinal dysraphism after surgical closure with or without a VP shunt using ASQ-3<sup>TM</sup> Scores. Methodology: This is a retrospective hospital-based study of 84 patients who underwent myelomeningocele repair at the National Center for Neurological Sciences (NCNS) during the period from 2017 up to 2019. Data were collected through a constructed questionnaire, including ASQ-3<sup>TM</sup> Scores. Data were processed and analyzed using the Statistical Package for Social Science (SPSS) computer program. Version 25. Results: 84 patients were included in this study;all patients were diagnosed with spinal dysraphism. Out of them, 51 (60.7%) were 2 years old, 33 (39.3%) were 3 years old, 45 (53.6%) were male, 45 (53.6%) of patients mothers attended ANC irregularly, and 54 (64.3%) their mothers didn’t receive folate supplements. 44 (52.3%) of patients underwent MMC repair only, while 40 (47.7%) underwent MMC repair and VP shunt. The commonest postoperative complication was infection, reported in 12 (14.3%) of patients, followed by VP shunt revision in 9 (10.7%) of patients. Neurological assessment showed that the majority of patients need further assessment with a professional, 57 (67.9%) of children don’t walk, run, or climb like other toddlers as their parent’s state;also, half of patients (42, 50%) had medical problems, and 27 (32.1%) of their parent’s state that they do not talk like other toddlers their age. There was a statistically significant association between post-operative complications and communication development, problem-solving development, and personal social development (P value = 0.05), and a statistically significant association was found between age at repair and neurological development (P value = 0.05). Conclusion: The majority of patients had motor deficiency (particularly gross motor) and poor personal and social skills. Age at repair and postoperative complications significantly influenced the neurological development.

文摘The recent identification of a neurodevelopmental disorder with cerebellar atrophy and motor dysfunction(NEDCAM)has resulted in an increased interest in GEMIN5,a multifunction RNA-binding protein.As the largest member of the survival motor neuron complex,GEMIN5 plays a key role in the biogenesis of small nuclear ribonucleoproteins while also exhibiting translational regulatory functions as an independent protein.Although many questions remain regarding both the pathogenesis and pathophysiology of this new disorder,considerable progress has been made in the brief time since its discovery.In this review,we examine GEMIN5 within the context of NEDCAM,focusing on the structure,function,and expression of the protein specifically in regard to the disorder itself.Additionally,we explore the current animal models of NEDCAM,as well as potential molecular pathways for treatment and future directions of study.This review provides a comprehensive overview of recent advances in our understanding of this unique member of the survival motor neuron complex.
文摘Objective: This study aimed to assess perinatal morbidity, mortality rates, and neurodevelopmental outcomes in the management of fetal growth restriction (FGR) at a single tertiary institute. Methods: Among 2465 deliveries between 2013 and 2019, 109 cases of FGR were reviewed retrospectively for causes, indications for pregnancy termination, perinatal death, overall neonatal outcomes, and long-term prognosis. Results: Excluding FGR due to congenital anomalies (n = 17), the mortality rate was 3.3% (3/92). One neonate delivered at 23 weeks developed cerebral palsy (1.1%). Retinopathy of prematurity occurred in four neonates (4.3%). Neurodevelopmental disorders were present in six neonates (6.5%), all of whom were delivered at 32 - 38 weeks. Significantly lower gestational age at delivery, lower birth weight, and higher umbilical artery resistance indices were observed in neonates with neurodevelopmental disorders. Conclusions: Intact survival before 27 weeks of gestation at delivery with FGR is uncommon. Neurodevelopmental disorders may still develop after delivery at 32 - 38 weeks;consideration should be given to the timing of delivery usingfetal ductus venosus Doppler waveforms measurements to reduce neurodevelopmental disorders.

文摘Tributyltin(TBT),a common organotin environmental pollutant,may pose a threat to human development during critical early-life periods.We aimed to assess the neurodevelopmental intergenerational toxicity of early-life exposure to TBT and the protective effect of DNA methyl donor folic acid(FA).Specifically,after early-life exposure(1–21 days postfertilization,dpf)to TBT(0,1,10 and 100 ng/L),zebrafish(Danio rerio)were cultured in clean medium until sexual maturity.The exposed females were mated with unexposed males to produce embryos(F1).The F1 generation were cultured(4–120 hours post-fertilization,hpf)with and without 1 mmol/L FA.The neurotoxic effects of early-life TBT exposure for zebrafish and their offspring(F1)were significantly enhanced anxiety and reduced aggression,decreased gene expression of DNA methyltransferase in the brain and increased serotonin levels in the body.Moreover,the intergenerational neurodevelopmental toxicity,as manifested in the F1 generation,was attenuated by FA supplementation.In summary,early-life TBT exposure led to intergenerational neurodevelopmental deficits in zebrafish,and DNA methyl donors had a protective effect on F1 neurodevelopment,which can inform the prevention and treatment of intergenerational neurotoxicity due to organotin pollutants.
文摘Neurodevelopmental disorders are characterized by an abnormal development of the central nervous system, leading to a myriad of symptoms and diseases, including intellectual disability, attention deficits, impairments in learning and memory, speech disorders and repetitive behavior （Telias and Ben-Yosef, 2014）. Common major neurodevelopmental disorders include autism and autism spectrum disorders （ASDs）, fragile X syndrome （FXS）, Down syndrome （DS）, and Rett syndrome （RTT）. They can be collectively described as disorders in which the plasticity of the brain has been severely impaired. The concept of plasticity refers to the brain＇s ability to adapt to and process new information and react accordingly, and it can be classified into three categories： a） molecular plasticity, whenever specific receptors, ion channels, enzymes,

文摘Autism spectrum disorder(ASD)is a group of neurodevelopmental disorders that cause severe social,communication,and behavioral problems.Recent studies show that the variants of a histone methyltransferase gene KMT5B cause neurodevelopmental disorders(NDDs),including ASD,and the knockout of Kmt5b in mice is embryonic lethal.However,the detailed genotype-phenotype correlations and functional effects of KMT5B in neurodevelopment are unclear.By targeted sequencing of a large Chinese ASD cohort,analyzing published genome-wide sequencing data,and mining literature,we curated 39 KMT5B variants identified from NDD individuals.A genotype-phenotype correlation analysis for 10 individuals with KMT5B pathogenic variants reveals common symptoms,including ASD,intellectual disability,languages problem,and macrocephaly.In vitro knockdown of the expression of Kmt5b in cultured mouse primary cortical neurons leads to a decrease in neuronal dendritic complexity and an increase in dendritic spine density,which can be rescued by expression of human KMT5B but not that of pathogenic de novo missense mutants.In vivo knockdown of the Kmt5b expression in the mouse embryonic cerebral cortex by in utero electroporation results in decreased proliferation and accelerated migration of neural progenitor cells.Our findings reveal essential roles of histone methyltransferase KMT5B in neuronal development,prenatal neurogenesis,and neuronal migration.

文摘Mice use ultrasonic vocalizations(USVs)to communicate each other and to convey their emotional state.USVs have been greatly characterized in specific life phases and contexts,such as mother isolation-induced USVs for pups or female-induced USVs for male mice during courtship.USVs can be acquired by means of specific tools and later analyzed on the base of both quantitative and qualitative parameters.Indeed,different ultrasonic call categories exist and have already been defined.The understanding of different calls meaning is still missing,and it will represent an essential step forward in the field of USVs.They have long been studied in the ethological context,but recently they emerged as a precious instrument to study pathologies characterized by deficits in communication,in particular neurodevelopmental disorders(NDDs),such as autism spectrum disorders.This review covers the topics of USVs characteristics in mice,contexts for USVs emission and factors that modulate their expression.A particular focus will be devoted to mouse USVs in the context of NDDs.Indeed,several NDDs murine models exist and an intense study of USVs is currently in progress,with the aim of both performing an early diagnosis and to find a pharmacological/behavioral intervention to improve patients’quality of life.
文摘Survival of preterm infants has been steadily improving in recent years because of many recent advances in perinatal and neonatal medicine.Despite these advances,the growth of survivors does not reach the ideal target level of the normal fetus of the same gestational age.Postnatal weight gain is often not achieved because extrauterine growth has higher energy requirements than intrauterine growth,due to the intensive care environment,illness and inadequate nutrition.Although many other factors influence infant brain development,including family socioeconomic and educational background,the role of nutrition is considerable and fortunately,amenable to intervention.In the preterm neonate,the brain is the most metabolically demanding organ,consuming the largest proportions of energy and nutrient intake for its function and programmed growth and maturation.Weight gain,linear and head circumference growth are all markers of nutritional status and are independently associated with long-term neurodevelopment.Brain development is not only the result of nutrients intake,but in addition,of the interaction with growth factors which depend on adequate nutrient supply and overall health status.This explains why conditions such as sepsis,necrotizing enterocolitis and chronic lung disease alter the distribution and accretion of nutrients thereby suppressing growth factor synthesis.In this review,we will focus on the direct role of nutrition on neurodevelopment,emphasizing why it should be started without delay.The nutritional requirements of the preterm infant will be discussed,followed by the effects of general nutritional interventions and specific nutrients,as well as the role of nutritional supplements on neurodevelopment.The primordial role of human breast milk,breast milk fortifiers and human milk oligosaccharides will be discussed in detail.We will also examine the role of nutrition in preventing neonatal complications which can affect neurodevelopment in their own right.
文摘There is a complex relationship between sleep disorders and childhood neurodevelopmental,emotional,behavioral and intellectual disorders(NDEBID).NDEBID include several conditions such as attention deficit/hyperactivity disorder,autism spectrum disorder,cerebral palsy,epilepsy and learning(intellectual)disorders.Up to 75%of children and young people(CYP)with NDEBID are known to experience different types of insomnia,compared to 3%to 36%in normally developing population.Sleep disorders affect 15%to 19%of adolescents with no disability,in comparison with 26%to 36%among CYP with moderate learning disability(LD)and 44%among those with severe LD.Chronic sleep deprivation is associated with significant risks of behavioural problems,impaired cognitive development and learning abilities,poor memory,mood disorders and school problems.It also increases the risk of other health outcomes,such as obesity and metabolic consequences,significantly impacting on the wellbeing of other family members.This narrative review of the extant literature provides a brief overview of sleep physiology,aetiology,classification and prevalence of sleep disorders among CYP with NDEBIDs.It outlines various strategies for the management,including parenting training/psychoeducation,use of cognitive-behavioral strategies and pharmacotherapy.Practical management including assessment,investigations,care plan formulation and follow-up are outlined in a flow chart.
文摘‘Neurodevelopmental disorders’comprise a group of congenital or acquired longterm conditions that are attributed to disturbance of the brain and or neuromuscular system and create functional limitations,including autism spectrum disorder,attention deficit/hyperactivity disorder,tic disorder/Tourette’s syndrome,developmental language disorders and intellectual disability.Cerebral palsy and epilepsy are often associated with these conditions within the broader framework of paediatric neurodisability.Co-occurrence with each other and with other mental health disorders including anxiety and mood disorders and behavioural disturbance is often the norm.Together these are referred to as neurodevelopmental,emotional,behavioural,and intellectual disorders(NDEBIDs)in this paper.Varying prevalence rates for NDEBID have been reported in developed countries,up to 15%,based on varying methodologies and definitions.NDEBIDs are commonly managed by either child health paediatricians or child/adolescent mental health(CAMH)professionals,working within multidisciplinary teams alongside social care,education,allied healthcare practitioners and voluntary sector.Fragmented services are common problems for children and young people with multi-morbidity,and often complicated by subthreshold diagnoses.Despite repeated reviews,limited consensus among clinicians about classification of the various NDEBIDs may hamper service improvement based upon research.The recently developed“Mental,Behavioural and Neurodevelopmental disorder”chapter of the International Classification of Diseases-11 offers a way forward.In this narrative review we search the extant literature and discussed a brief overview of the aetiology and prevalence of NDEBID,enumerate common problems associated with current classification systems and provide recommendations for a more integrated approach to the nosology and clinical care of these related conditions.
