文摘Non-alcoholic fatty liver disease(NAFLD)is associated with mutations in lipopolysaccharide-binding protein(LBP),but the underlying epigenetic mechanisms remain understudied.Herein,LBP^(-/-)rats with NAFLD were established and used to conduct integrative targetingactive enhancer histone H3 lysine 27 acetylation(H3K27ac)chromatin immunoprecipitation coupled with high-throughput and transcriptomic sequencing analysis to explore the potential epigenetic pathomechanisms of active enhancers of NAFLD exacerbation upon LBP deficiency.Notably,LBP^(-/-)reduced the inflammatory response but markedly aggravated high-fat diet(HFD)-induced NAFLD in rats,with pronounced alterations in the histone acetylome and regulatory transcriptome.In total,1128 differential enhancer-target genes significantly enriched in cholesterol and fatty acid metabolism were identified between wild-type(WT)and LBP^(-/-)NAFLD rats.Based on integrative analysis,CCAAT/enhancer-binding proteinβ(C/EBPβ)was identified as a pivotal transcription factor(TF)and contributor to dysregulated histone acetylome H3K27ac,and the lipid metabolism gene SCD was identified as a downstream effector exacerbating NAFLD.This study not only broadens our understanding of the essential role of LBP in the pathogenesis of NAFLD from an epigenetics perspective but also identifies key TF C/EBPβand functional gene SCD as potential regulators and therapeutic targets.
文摘Non-alcoholic fatty liver disease(NAFLD)was the term first used to describe hepatic steatosis in patients with the metabolic syndrome who did not consume excess amounts of alcohol.Alcoholic liver disease(ALD)has many similarities to NAFLD in both pathogenesis and histology.This entity is now the most prevalent chronic liver disease worldwide as a consequence of the epidemic of obesity.Attempts to incorporate the importance of the metabolic syndrome in the development of steatosis resulted in the renaming of NAFLD as metabolic-associated fatty liver disease.This new term,however,has the disadvantage of the use of terms that may be perceived as derogatory.The terms fatty and non-alcoholic have negative connotations in many cultures.In addition,non-alcoholic is not usually a term applicable to pediatric cases of hepatic steatosis.Recently,an international collaborative effort,with participants from 56 countries,after a global consultation process,recommended to change the nomenclature to steatotic liver disease-including metabolic dysfunction-associated steatotic liver disease,metabolic-associated steatohepatitis and metabolic dysfunction-associated ALD.The new terminology is consistent with most of the previously published epidemiological studies and will have a major impact on research into diagnosis,prognosis and treatment.

文摘Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a“multi-omics”platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.
文摘Non-alcoholic fatty liver disease(NAFLD)is the most common chronic liver disease,defined by several phases,ranging from benign fat accumulation to non-alcoholic steatohepatitis(NASH),which can lead to liver cancer and cirrhosis.Although NAFLD is a disease of disordered metabolism,it also involves several immune cell-mediated inflammatory processes,either promoting and/or suppressing hepatocyte inflammation through the secretion of pro-inflammatory and/or anti-inflammatory factors to influence the NAFLD process.However,the underlying disease mechanism and the role of immune cells in NAFLD are still under investigation,leaving many open-ended questions.In this review,we presented the recent concepts about the interplay of immune cells in the onset and pathogenesis of NAFLD.We also highlighted the specific non-immune cells exhibiting immunological properties of therapeutic significance in NAFLD.We hope that this review will help guide the development of future NAFLD therapeutics.

文摘Caffeine intake during pregnancy is common,while its effect on gut microbiota composition of offspring and the relationship with susceptibility to adult diseases remains unclear.This study aimed to confirm the effects of prenatal caffeine exposure(PCE)on the gut microbiota composition and its metabolites in female offspring rats,and to further elucidate its underlying mechanism and intervention targets in adult non-alcoholic fatty disease(NAFLD).The results showed that the gut microbiota of PCE female offspring at multiple time points from infancy to adolescence were significantly changed with depletion of butyric acid-producing bacteria,leading to a decrease in butyric acid in adulthood.It was also found that PCE female offspring rats were sensitive to NAFLD induced by a postnatal high-fat diet(HFD),which is mainly related to the enhancement of hepatic triglyceride synthesis function.Through mechanism exploration,we found that HFD further reduced the fecal and serum butyric acid levels in the PCE female offspring,which was significantly negatively correlated with hepatic SREBP-1c/FASN mRNA expression and triglyceride level.In vivo and in vitro experiments confirmed that sodium butyrate(NaB)supplementation could reduce hepatic lipid accumulation through MCT1/GPR109A-AMPK,thereby effectively decreasing the susceptibility to NAFLD in the PCE female offspring rats.
文摘In this editorial,we commented on a recently released manuscript by Zeng et al in the World Journal of Gastroenterology.We focused specifically on lifestyle changes in patients with non-alcoholic fatty liver disease(NAFLD).NAFLD is a hepatic manifestation of the metabolic syndrome,which ultimately leads to advanced hepatic fibrosis,cirrhosis,and hepatocellular carcinoma and affects more than 25%of the population globally.Existing therapeutic strategies against NAFLD such as pharmacologic therapies focus on liver protection,anti-inflammation,and regulating disease-related metabolic disorder symptoms.Although several drugs are in late-stage development,potent drugs against the diseases are lacking.Additionally,existing surgical approaches such as bariatric surgery are not routinely used to treat NAFLD.Intervening in patients’unhealthy lifestyles,such as weight loss through dietary changes and exercises to ameliorate patientassociated metabolic disorders and metabolic syndrome,is the first-line treatment for patients with NAFLD.With sufficient intrinsic motivation and adherence,the management of unhealthy lifestyles can reduce the severity of the disease,improve the quality of life,and increase the survival expectancy of patients with NAFLD.

文摘Non-alcoholic fatty liver disease(NAFLD)is characterized by symptoms of excessive fat accumulation and steatosis in the liver without alcohol intake in patients.The associated pathogenic mechanism is not completely understood and there are no specific drugs for patients with NAFLD.Exercise and diet adherence are the best options for the management of NAFLD patients.Questionnaire associated analysis models of adherence to these interventions are used to assess their effectiveness in the management of NAFLD patients using specificity,sensitivity,and so on.Studies have indicated that the relative ratio of NAFLD can be reduced by physical activity with diet control.In the future,the pathogenesis of NAFLD should be clarified with stratified efforts to develop appropriate drugs,and both exercise and diet adherence should be optimized using better questionnaire design and evaluation models for patients with NAFLD.

文摘In this editorial,we comment on the article by Liu et al published in the recent issue of the World Journal of Diabetes(Relationship between GCKR gene rs780094 polymorphism and type 2 diabetes with albuminuria).Type 2 diabetes mellitus(T2DM)is a chronic disorder characterized by dysregulated glucose homeostasis.The persistent elevated blood glucose level in T2DM significantly increases the risk of developing severe complications,including cardiovascular disease,re-tinopathy,neuropathy,and nephropathy.T2DM arises from a complex interplay between genetic,epigenetic,and environmental factors.Global genomic studies have identified numerous genetic variations associated with an increased risk of T2DM.Specifically,variations within the glucokinase regulatory protein(GCKR)gene have been linked to heightened susceptibility to T2DM and its associated complications.The clinical trial by Liu et al further elucidates the role of the GCKR rs780094 polymorphism in T2DM and nephropathy development.Their findings demonstrate that individuals carrying the CT or TT genotype at the GCKR rs780094 locus are at a higher risk of developing T2DM with albuminuria compared to those with the CC genotype.These findings highlight the importance of genetic testing and risk assessment in T2DM to develop effective preventive strategies and personalized treatment plans.

文摘BACKGROUND The understanding of bile acid(BA)and unsaturated fatty acid(UFA)profiles,as well as their dysregulation,remains elusive in individuals with type 2 diabetes mellitus(T2DM)coexisting with non-alcoholic fatty liver disease(NAFLD).Investigating these metabolites could offer valuable insights into the pathophy-siology of NAFLD in T2DM.AIM To identify potential metabolite biomarkers capable of distinguishing between NAFLD and T2DM.METHODS A training model was developed involving 399 participants,comprising 113 healthy controls(HCs),134 individuals with T2DM without NAFLD,and 152 individuals with T2DM and NAFLD.External validation encompassed 172 participants.NAFLD patients were divided based on liver fibrosis scores.The analytical approach employed univariate testing,orthogonal partial least squares-discriminant analysis,logistic regression,receiver operating characteristic curve analysis,and decision curve analysis to pinpoint and assess the diagnostic value of serum biomarkers.RESULTS Compared to HCs,both T2DM and NAFLD groups exhibited diminished levels of specific BAs.In UFAs,particular acids exhibited a positive correlation with NAFLD risk in T2DM,while theω-6:ω-3 UFA ratio demonstrated a negative correlation.Levels ofα-linolenic acid andγ-linolenic acid were linked to significant liver fibrosis in NAFLD.The validation cohort substantiated the predictive efficacy of these biomarkers for assessing NAFLD risk in T2DM patients.CONCLUSION This study underscores the connection between altered BA and UFA profiles and the presence of NAFLD in individuals with T2DM,proposing their potential as biomarkers in the pathogenesis of NAFLD.

文摘BACKGROUND Many studies have revealed a link between non-alcoholic fatty liver disease(NA-FLD)and coronavirus disease 2019(COVID-19),making understanding the relationship between these two conditions an absolute requirement.AIM To provide a qualitative synthesis on the currently present data evaluating COVID-19 and NAFLD.METHODS This systematic review was conducted in accordance with the guidelines pro-vided by preferred reporting items for systematic reviews and meta-analyses and the questionnaire utilized the population,intervention,comparison,and outcome framework.The search strategy was run on three separate databases,PubMed/MEDLINE,Scopus,and Cochrane Central,which were systematically searched from inception until March 2024 to select all relevant studies.In addition,ClinicalTrials.gov,Medrxiv.org,and Google Scholar were searched to identify grey literature.RESULTS After retrieval of 11 studies,a total of 39282 patients data were pooled.Mortality was found in 11.5%and 9.4%of people in NAFLD and non-NAFLD groups.In all,23.2%of NAFLD patients and 22%of non-NAFLD admissions diagnosed with COVID-19 were admitted to the intensive care unit,with days of stay varying.Ventilatory support ranged from 5%to 40.5%in the NAFLD cohort and from 3.1%to 20%in the non-NAFLD cohort.The incidence of acute liver injury showed significance.Clinical improvement on days 7 and 14 between the two classifications was significant.Hospitalization stay ranged from 9.6 days to 18.8 days and 7.3 days to 16.4 days in the aforementioned cohorts respectively,with 73.3%and 76.3%of patients being discharged.Readmission rates varied.CONCLUSION Clinical outcomes except mortality consistently showed a worsening trend in patients with NAFLD and concomitant COVID-19.Further research in conducting prospective longitudinal studies is essential for a more powerful conclusion.
文摘BACKGROUND There are limited studies investigating the association between type 2 diabetes mellitus(T2DM)and non-alcoholic fatty liver disease(NAFLD)in the region of Bihar,India.AIM To estimate the prevalence of NAFLD in persons with newly diagnosed T2DM in the population of North Bihar,India.METHODS This single centre cross-sectional study was undertaken in the Research Centre for Diabetes Hypertension and Obesity,Samastipur,Bihar,India.Data were collected from persons newly diagnosed with T2DM or those diagnosed within 6 months of when the study was conducted between December 2022 to May 2023.RESULTS A total of 148 people with newly diagnosed T2DM were included(median age 47 years,46.6%female)and 109 patients with liver disease on ultrasound evaluation.The persons with liver disease consumed more fats and oils(88.1%vs 74.4%,P=0.042)and they had significantly greater body mass index(27.4 vs 23.0,P<0.001),waist circumference(37 vs 33,P<0.001),and waist-to-hip ratio(1.00 vs 0.70,P=0.025).Females were associated with greater liver disease[odds ratio(OR):3.09,95%confidence interval(CI):1.09-8.80,P=0.32].Waist circumference(OR:1.42,95%CI:1.22-1.66,P<0.001)and low-density lipoprotein cholesterol(OR:1.01,95%CI:1.01-1.02,P=0.048)were associated with any liver disease.The factors most associated with grade 2/3 liver disease was right upper quadrant pain or heaviness(OR:5.22,95%CI:1.40-19.41,P=0.14),greater income(OR:3.58,95%CI:1.28-10.04,P=0.015)and waist circumference(OR:1.31,95%CI:1.02-1.69,P=0.036).CONCLUSION NAFLD is common in new/recently diagnosed T2DM and disease burden is high and common among patients who are either high consumers of fats and oils or have obesity-associated markers.

文摘Studies have shown that non-alcoholic fatty liver disease(NAFLD)may be associated with sleep disorders.In order to explore the explicit relationship between the two,we systematically reviewed the effects of sleep disorders,especially obstructive sleep apnea(OSA),on the incidence of NAFLD,and analyzed the possible mechanisms after adjusting for confounding factors.NAFLD is independently associated with sleep disorders.Different sleep disorders may be the cause of the onset and aggravation of NAFLD.An excessive or insufficient sleep duration,poor sleep quality,insomnia,sleep-wake disorders,and OSA may increase the incidence of NAFLD.Despite that some research suggests a unidirectional causal link between the two,specifically,the onset of NAFLD is identified as a result of changes in sleep characteristics,and the reverse relationship does not hold true.Nevertheless,there is still a lack of specific research elucidating the reasons behind the higher risk of developing sleep disorders in individuals with NAFLD.Further research is needed to establish a clear relationship between NAFLD and sleep disorders.This will lay the groundwork for earlier identification of potential patients,which is crucial for earlier monitoring,diagnosis,effective prevention,and treatment of NAFLD.
文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular diseases independently of other risk factors.However,data on its effect on cardiovascular outcomes in coronavirus disease 2019(COVID-19)hospitalizations with varied obesity levels is scarce.Clinical management and patient care depend on understanding COVID-19 admission results in NAFLD patients with varying obesity levels.AIM To study the in-hospital outcomes in COVID-19 patients with NAFLD by severity of obesity.METHODS COVID-19 hospitalizations with NAFLD were identified using International Classification of Disease-10 CM codes in the 2020 National Inpatient Sample database.Overweight and Obesity Classes Ⅰ,Ⅱ,and Ⅲ(body mass index 30-40)were compared.Major adverse cardiac and cerebrovascular events(MACCE)(all-cause mortality,acute myocardial infarction,cardiac arrest,and stroke)were compared between groups.Multivariable regression analyses adjusted for sociodemographic,hospitalization features,and comorbidities.RESULTS Our analysis comprised 13260 hospitalizations,7.3% of which were overweight,24.3% Class Ⅰ,24.1% Class Ⅱ,and 44.3% Class Ⅲ.Class Ⅲ obesity includes younger patients,blacks,females,diabetics,and hypertensive patients.On multivariable logistic analysis,Class Ⅲ obese patients had higher risks of MACCE,inpatient mortality,and respiratory failure than Class Ⅰ obese patients.Class Ⅱ obesity showed increased risks of MACCE,inpatient mortality,and respiratory failure than Class I,but not significantly.All obesity classes had non-significant risks of MACCE,inpatient mortality,and respiratory failure compared to the overweight group.CONCLUSION Class Ⅲ obese NAFLD COVID-19 patients had a greater risk of adverse outcomes than class Ⅰ.Using the overweight group as the reference,unfavorable outcomes were not significantly different.Morbid obesity had a greater risk of MACCE regardless of the referent group(overweight or Class Ⅰ obese)compared to overweight NAFLD patients admitted with COVID-19.
