Secreted Frizzled-Related Protein 5 Mediates Wnt5a Expression in Microcystin-Leucine-Arginine-Induced Liver Lipid Metabolism Disorder in Mice

Objective Microcystin-leucine-arginine(MC-LR)exposure induces lipid metabolism disorders in the liver.Secreted frizzled-related protein 5(SFRP5)is a natural antagonist of winglesstype MMTV integration site family,member 5A(Wnt5a)and an anti-inflammatory adipocytokine.In this study,we aimed to investigate whether MC-LR can induce lipid metabolism disorders in hepatocytes and whether SFRP5,which has anti-inflammatory effects,can alleviate the effects of hepatic lipid metabolism by inhibiting the Wnt5a/Jun N-terminal kinase(JNK)pathway.Methods We exposed mice to MC-LR in vivo to induce liver lipid metabolism disorders.Subsequently,mouse hepatocytes that overexpressed SFRP5 or did not express SFRP5 were exposed to MC-LR,and the effects of SFRP5 overexpression on inflammation and Wnt5a/JNK activation by MC-LR were observed.Results MC-LR exposure induced liver lipid metabolism disorders in mice and significantly decreased SFRP5 mRNA and protein levels in a concentration-dependent manner.SFRP5 overexpression in AML12cells suppressed MC-LR-induced inflammation.Overexpression of SFRP5 also inhibited Wnt5a and phosphorylation of JNK.Conclusion MC-LR can induce lipid metabolism disorders in mice,and SFRP5 can attenuate lipid metabolism disorders in the mouse liver by inhibiting Wnt5a/JNK signaling.

Huangqin decoction alleviates lipid metabolism disorders and insulin resistance in nonalcoholic fatty liver disease by triggering Sirt1/NF-κB pathway

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is a clinicopathological entity characterized by intrahepatic ectopic steatosis.As a consequence of increased consumption of high-calorie diet and adoption of a sedentary lifestyle,the incidence of NAFLD has surpassed that of viral hepatitis,making it the most common cause of chronic liver disease globally.Huangqin decoction(HQD),a Chinese medicinal formulation that has been used clinically for thousands of years,has beneficial outcomes in patients with liver diseases,including NAFLD.However,the role and mechanism of action of HQD in lipid metabolism disorders and insulin resistance in NAFLD remain poorly understood.AIM To evaluate the ameliorative effects of HQD in NAFLD,with a focus on lipid metabolism and insulin resistance,and to elucidate the underlying mechanism of action.METHODS High-fat diet-induced NAFLD rats and palmitic acid(PA)-stimulated HepG2 cells were used to investigate the effects of HQD and identify its potential mechanism of action.Phytochemicals in HQD were analyzed by highperformance liquid chromatography(HPLC)to identify the key components.RESULTS Ten primary chemical components of HQD were identified by HPLC analysis.In vivo,HQD effectively prevented rats from gaining body and liver weight,improved the liver index,ameliorated hepatic histological aberrations,decreased transaminase and lipid profile disorders,and reduced the levels of pro-inflammatory factors and insulin resistance.In vitro studies revealed that HQD effectively alleviated PA-induced lipid accumulation,inflammation,and insulin resistance in HepG2 cells.In-depth investigation revealed that HQD triggers Sirt1/NF-κB pathwaymodulated lipogenesis and inflammation,contributing to its beneficial actions,which was further corroborated by the addition of the Sirt1 antagonist EX-527 that compromised the favorable effects of HQD.CONCLUSION In summary,our study confirmed that HQD mitigates lipid metabolism disorders and insulin resistance in NAFLD by triggering the Sirt1/NF-κB pathway.

Inonotus obliquus(Chaga)against HFD/STZ-induced glucolipid metabolism disorders and abnormal renal functions by regulating NOS-cGMP-PDE5 signaling pathway

Our prior investigations have established that Inonotus obliquus(Chaga)possesses hypoglycemic effects.Persistent hyperglycemia is known to precipitate renal function abnormalities.The functionality of the kidneys is intricately linked to the levels of cyclic guanosine-3',5'-monophosphate(cGMP),which are influenced by the activities of nitric oxide synthase(NOS)and phosphodiesterase(PDE).Enhanced cGMP levels can be achieved either through the upregulation of NOS activity or the downregulation of PDE activity.The objective of the current study is to elucidate the effects of Chaga on disorders of glucolipid metabolism and renal abnormalities in rats with type 2 diabetes mellitus(T2DM),while concurrently examining the NOS-cGMP-PDE5 signaling pathway.A model of T2DM was developed in rats using a high-fat diet(HFD)combined with streptozotocin(STZ)administration,followed by treatment with Chaga extracts at doses of 50 and 100 mg·kg^(−1)for eight weeks.The findings revealed that Chaga not only mitigated metabolic dysfunctions,evidenced by improvements in fasting blood glucose,total cholesterol,triglycerides,and insulin resistance,but also ameliorated renal function markers,including serum creatinine,urine creatinine(UCr),blood urea nitrogen,24-h urinary protein,and estimated creatinine clearance.Additionally,enhancements in glomerular volume,GBM thickness,podocyte foot process width(FPW),and the mRNA and protein expressions of podocyte markers,such as nephrin and wilms tumor-1,were observed.Chaga was found to elevate cGMP levels in both serum and kidney tissues by increasing mRNA and protein expressions of renal endothelial NOS and neural NOS,while simultaneously reducing the expressions of renal inducible NOS and PDE5.In summary,Chaga counteracts HFD/STZ-induced glucolipid metabolism and renal function disturbances by modulating the NOS-cGMP-PDE5 signaling pathway.This research supports the potential application of Chaga in the clinical prevention and treatment of T2DM and diabetic nephropathy(DN),with cGMP serving as a potential therapeutic target.

Cardiac energy metabolism disorder mediated by energy substrate imbalance and mitochondrial damage upon tebuconazole exposure

Tebuconazole exposure has been described as an increasing hazard to human health.An increasing number of recent studies have shown a positive association between tebuconazole exposure and cardiovascular disease risk,which is characterized by the reduction of adenosine triphosphate(ATP)synthesis.However,researches on the damage of tebuconazole exposure to energy metabolism and the related molecular mechanisms are limited.In the present study,male C57BL/6 mice were treated with tebuconazole at different low concentrations for 4 weeks.The results indicated that tebuconazole could accumulate in the heart and further induce the decrease of ATP content in the mouse heart.Importantly,tebuconazole induced an obvious shift in substrate utilization of fatty acid and glucose by disrupting their corresponding transporters(GLUT1,GLUT4,CD36,FABP3 and FATP1)expression,and significantly repressed the expression of mitochondrial biogenesis(Gabpa and Tfam)and oxidative phosphorylation(CS,Ndufa4,Sdhb,Cox5a and Atp5b)related genes in a dosedependent manner.Further investigation revealed that these alterations were related to the IRS1/AKT and PPARγ/RXRαpathways.These findings contribute to a better understanding of triazole fungicide-induced cardiovascular disease by revealing the key indicators associated with this phenomenon.

Transcriptome reveals overview of Ca^(2+) dose-dependent metabolism disorders in zebrafish larvae after Cd^(2+) exposure

Cadmium (Cd),a ubiquitous environmental hazardous heavy metal,poses a significant threat to the health of aquatic organisms,including teleosts.Although the toxic profile of Cd is well recognized,little is known regarding the overall view of toxic responses to varying aquatic environmental parameters (e.g.,water hardness) at an individual level.Herein,differences in water hardness were partially mimicked by adjusting Ca^(2+)levels in E3 medium.As an in vivo model,zebrafish embryos were exposed to variable Ca^(2+)levels (NV,normal Ca^(2+);LV,low Ca^(2+);HV,high Ca^(2+)) alone or combined with 30.7μg/L Cd^(2+)(NC,LC,and HC,respectively) until 144 hr post-fertilization.The genome-wide transcriptome revealed differentially expressed genes between groups.Functional enrichment analysis found that biological processes related to metabolism,particularly lipid metabolism,were significantly disrupted in NC and LC treatments,while a remission was observed in the HC group.Biochemical assays confirmed that the decrease in Ca^(2+)enhanced synthesis,inhibited mobilization and increased the storage of lipids in Cd^(2+)treatments.This study suggests that the toxic effect of Cd on biological pathways will be influenced by Ca^(2+),which will improve the toxicological understanding and facilitate accurate assessment of Cd.

The Role of Adipose Tissue-derived Exosomes in Chronic Metabolic Disorders

Excessive fat deposition in obese subjects promotes the occurrence of metabolic diseases,such as type 2 diabetes mellitus(T2DM),cardiovascular diseases,and non-alcoholic fatty liver disease(NAFLD).Adipose tissue is not only the main form of energy storage but also an endocrine organ that not only secretes adipocytokines but also releases many extracellular vesicles(EVs)that play a role in the regulation of whole-body metabolism.Exosomes are a subtype of EVs,and accumulating evidence indicates that adipose tissue exosomes(AT Exos)mediate crosstalk between adipose tissue and multiple organs by being transferred to targeted cells or tissues through paracrine or endocrine mechanisms.However,the roles of AT Exos in crosstalk with metabolic organs remain to be fully elucidated.In this review,we summarize the latest research progress on the role of AT Exos in the regulation of metabolic disorders.Moreover,we discuss the potential role of AT Exos as biomarkers in metabolic diseases and their clinical application.

Asiaticoside ameliorates type 2 diabetes mellitus in rats by modulating carbohydrate metabolism and regulating insulin signaling

Objective:To evaluate the effect of asiaticoside on streptozotocin(STZ)and nicotinamide(NAD)-induced carbohydrate metabolism abnormalities and deregulated insulin signaling pathways in rats.Methods:Asiaticoside(50 and 100 mg/kg body weight)was administered to STZ-NAD-induced diabetic rats for 45 days,and its effects on hyperglycaemic,carbohydrate metabolic,and insulin signaling pathway markers were examined.Results:Asiaticoside increased insulin production,lowered blood glucose levels,and enhanced glycolysis by improving hexokinase activity and suppressing glucose-6-phosphatase and fructose-1,6-bisphosphatase activities.Abnormalities in glycogen metabolism were mitigated by increasing glycogen synthase activity and gluconeogenesis was decreased by decreasing glycogen phosphorylase activity.Furthermore,asiaticoside upregulated the mRNA expressions of IRS-1,IRS-2,and GLUT4 in STZ-NAD-induced diabetic rats and restored the beta cell morphology to normal.Conclusions:Asiaticoside has the potential to ameliorate type 2 diabetes by improving glycolysis,gluconeogenesis,and insulin signaling pathways.

Estrogen deficiency exacerbates learning and memory deficits associated with glucose metabolism disorder in APP/PS1 double transgenic female mice

Alterations in glucose metabolism occur in the brain in the early stage of Alzheimer's disease(AD),and menopausal women have more severe metabolic dysfunction and are more prone to dementia than men.Although estrogen deficiency-induced changes in glucose metabolism have been previously studied in animal models,their molecular mechanisms in AD remain elusive.To investigate this issue,double transgenic(APP/PS1)female mice were subjected to bilateral ovariectomy at 3 months of age and were sacrificed 1 week,1 month and 3 months after surgery to simulate early,middle and late postmenopause,respectively.Our analysis demonstrated that estrogen deficiency exacerbates learning and memory deficits in this mouse model of postmenopause.Estrogen deficiency impairs the function of mitochondria in glucose metabolism.It is possible that the occurrence of AD is associated with the aberrant mitochondrial ERβ-mediated IGF-1/IGF-1R/GSK-3βsignaling pathway.In this study,we established a potential mechanism for the increased risk of AD in postmenopausal women and proposed a therapeutic target for AD due to postmenopause.

Uridine diphosphate glucuronosyltransferase 1A1 prevents the progression of liver injury

BACKGROUND Uridine diphosphate glucuronosyltransferase 1A1(UGT1A1)plays a crucial role in metabolizing and detoxifying endogenous and exogenous substances.However,its contribution to the progression of liver damage remains unclear.AIM To determine the role and mechanism of UGT1A1 in liver damage progression.METHODS We investigated the relationship between UGT1A1 expression and liver injury through clinical research.Additionally,the impact and mechanism of UGT1A1 on the progression of liver injury was analyzed through a mouse model study.RESULTS Patients with UGT1A1 gene mutations showed varying degrees of liver damage,while patients with acute-onchronic liver failure(ACLF)exhibited relatively reduced levels of UGT1A1 protein in the liver as compared to patients with chronic hepatitis.This suggests that low UGT1A1 levels may be associated with the progression of liver damage.In mouse models of liver injury induced by carbon tetrachloride(CCl_(4))and concanavalin A(ConA),the hepatic levels of UGT1A1 protein were found to be increased.In mice with lipopolysaccharide or liver steatosis-mediated liver-injury progression,the hepatic protein levels of UGT1A1 were decreased,which is consistent with the observations in patients with ACLF.UGT1A1 knockout exacerbated CCl_(4)-and ConA-induced liver injury,hepatocyte apoptosis and necroptosis in mice,intensified hepatocyte endoplasmic reticulum(ER)stress and oxidative stress,and disrupted lipid metabolism.CONCLUSION UGT1A1 is upregulated as a compensatory response during liver injury,and interference with this upregulation process may worsen liver injury.UGT1A1 reduces ER stress,oxidative stress,and lipid metabolism disorder,thereby mitigating hepatocyte apoptosis and necroptosis.

Effect of Dendrobium nobile powder combined with conventional therapy on mild to moderate fatty liver

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)encompasses a variety of liver conditions impacting individuals who consume minimal or no alcohol.Recently,traditional Chinese medicine has been gradually used to treat mild to moderate fatty liver,among which Dendrobium nobile Lindl.powder has been affirmed by many doctors and patients to be effective.However,there is limited research on combining this treatment with standard therapies for mild to moderate NAFLD.AIM To survey the effect of combining Dendrobium nobile Lindl.powder with standard treatment on liver function and lipid metabolism disorder in patients with mild to moderate NAFLD.METHODS Eighty patients with mild to moderate NAFLD participated in this retrospective study,classified into two groups:The observation group(n=40)and the control group(n=40).In November 2020 and November 2022,the study was conducted at People’s Hospital of Chongqing Liang Jiang New Area.The control group received standard treatment,while the observation group received Dendrobium nobile Lindl.powder based on the control group.The study compared differences in traditional Chinese medicine clinical syndrome scores,liver fibrosis treatment,liver function indicators,lipid levels,and serum inflammatory factor levels before and after treatment,and we calculated the incidence of adverse reactions for both groups.RESULTS The total effective rate was 97.50%in the observation group and 72.5%in the control group.After 8 weeks of treatment,the main and secondary symptom scores remarkably decreased,especially in the observation group(P<0.05),and there was a significant reduction in the serum levels of hyaluronic acid(HA),laminin(LN),human rocollagen III(PC III),and collagen type IV(CIV).The levels of HA,LN,PC III,and CIV were significantly lower in the observation group(P<0.05).After 8 weeks,both groups indicated remarkable improvements in liver function and blood lipid levels,with the observation group having even lower levels(P<0.05).Serum levels of interleukin-1β,tumor necrosis factor-α,and interleukin-8 also dropped significantly.The observation group had a lower rate of adverse reactions(5.00%)compared to the control group(22.50%).CONCLUSION Adding Dendrobium nobile Lindl.powder to standard treatment has been found to remarkably improve symptoms and reduce inflammation in patients with mild to moderate fatty liver disease.It also enhances hepatic function and lipid profile,ameliorates liver fibrosis indices,and lowers the risk of side effects.Consequently,this therapeutic protocol shows promise for clinical implementation and dissemination.

The current letter to the editor pertains to the manuscript entitled'Uridine diphosphate glucuronosyltransferase 1A1 prevents the progression of liver injury'.Increased levels of uridine diphosphate glucuronosyltransferase 1A1 during liver injury could mitigate damage by reducing endoplasmic reticulum stress,oxidative stress,and dysregulated lipid metabolism,impeding hepatocyte apoptosis and necroptosis.

Comparative Efficacy of Lifestyle Modifications versus Pharmacotherapy on Weight Loss and Metabolic Health Outcomes: A Comprehensive Review

Background: Obesity has become a serious global public health challenge, given that it leads to various adverse health outcomes that include cardiovascular illnesses, diabetes, and certain types of cancer. The World Health Organization (WHO) has estimated that, at the end of 2022, 1 out of every 8 individuals were obese, and that the global adult obesity rates have over doubled since 1990, even as the adolescent obesity rates have quadrupled. Thus, as of 2022, nearly 2.5 billion adults, aged 18 years and above, were overweight, with 890 million being obese. Obesity and overweight incidence rate has been gradually increasing over the years, presenting significant challenges to the healthcare systems throughout the globe. In this regard, the objective of this systematic review was to evaluate the effectiveness and safety of lifestyle modifications (diet and physical activity) and pharmacotherapy in promoting weight loss and improving metabolic health in overweight adults. Methodology: To attain the above stated study objective, a systematic evaluation of previous studies was carried out, particularly studies that assessed the effectiveness and safety of lifestyle modifications (diet and physical activity) and pharmacotherapy in promoting weight loss and improving metabolic health in overweight adults. The authors have used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in the selection of eligible studies for inclusion in the study. Results: The findings indicate that lifestyle interventions resulted in 5% - 10% weight reduction and significant improvements in metabolic indicators, while pharmacotherapy (GLP-1 receptor agonists) achieved up to 15% weight reduction and considerable metabolic health benefits. Further, comparative studies show lifestyle modifications provide overall health benefits, while medication is necessary for non-responders. Conclusion: Individualized treatment strategies are crucial, and further research is needed on long-term consequences and combination therapies.

Roles of fibroblast growth factors in the treatment of diabetes

Diabetes affects about 422 million people worldwide,causing 1.5 million deaths each year.However,the incidence of diabetes is increasing,including several types of diabetes.Type 1 diabetes(5%-10%of diabetic cases)and type 2 diabetes(90%-95%of diabetic cases)are the main types of diabetes in the clinic.Accumulating evidence shows that the fibroblast growth factor(FGF)family plays important roles in many metabolic disorders,including type 1 and type 2 diabetes.FGF consists of 23 family members(FGF-1-23)in humans.Here,we review current findings of FGFs in the treatment of diabetes and management of diabetic complications.Some FGFs(e.g.,FGF-15,FGF-19,and FGF-21)have been broadly investigated in preclinical studies for the diagnosis and treatment of diabetes,and their therapeutic roles in diabetes are currently under investigation in clinical trials.Overall,the roles of FGFs in diabetes and diabetic complications are involved in numerous processes.First,FGF intervention can prevent high-fat diet-induced obesity and insulin resistance and reduce the levels of fasting blood glucose and triglycerides by regulating lipolysis in adipose tissues and hepatic glucose production.Second,modulation of FGF expression can inhibit renal and cardiac fibrosis by regulating the expression of extracellular matrix components,promote diabetic wound healing process and bone repair,and inhibit cancer cell proliferation and migration.Finally,FGFs can regulate the activation of glucoseexcited neurons and the expression of thermogenic genes.

AIM: To study the prevalence and clinical biochemical, blood cell and metabolic features of lean-non-alcoholic fatty liver disease (lean-NAFLD) and its association with other diseases.

Gastric xanthelasma and metabolic disorders: A large retrospective study among Chinese population

AIM To gain knowledge of xanthelasma,a large populationbased study was conducted. METHODS Patients who underwent upper gastrointestinal endoscopy at the First Affiliated Hospital,College of Medicine,Zhejiang University,Hangzhou,China during Jan 2009 to Nov 2016 were included. General characteristics as well as clinical data were collected,including blood routine,serum biochemical analysis,endoscopic findinds,histological evaluation and comorbiditie. Statistical analyses was performed using SPSS 20.0 software for Windows(IBM Inc.,Chicago,IL,United States) using Student's t-test,Mann-Whitney U test,χ2 test,univariable and multivariable logistic analysis. 2-tailed P value less than 0.05 was considered to be statistically significant. RESULTS A total of 176006 endoscopies were retrieved and we included 1370 xanthelasma participants(703 men,667 women) in this study. Prevalence of xanthelasma was 0.78% with average age of 56.6 ± 11.2 years. Chief complaint of xanthelasma consisted abdominal pain (24.2%),up-abdominal discomfort(14.1%),abdominal distention(10.1%),dyspepsia(9.1%),et al. Most xanthelasma occurred as single lesion in gastric antrum. Xanthelasma patients witnessed higher Helicobacter pylori(H. pylori) infection rate,more of other gastric lesions including atrophy,intestinal metaplasia and dysplasia(P < 0.01). In xanthelasma patients,serum carcinoembryonic antigen,triglyceride,fasting glucose,neutrophil,neutrophil-to-lymphocyte ratio were significantly higher,and high density lipoprotein-cholesterol,lymphocyte was lower(P < 0.05). Xanthelasma accompanied with more fatty liver disease and hepatic cyst,but fewer gallbladder polyp(P < 0.05). In logistic regression,it revealed that fasting plasma glucose(OR = 3.347,1.170-9.575,P < 0.05),neutrophil(OR = 1.617,1.003-2.605,P < 0.05),and carcinoembryonic antigen(OR = 2.011,1.236-3.271,P < 0.01) were all independent risk factors in xanthelasma. CONCLUSION Current study described a large xanthelasma cohort in Chinese population,revealed its relationship with H. pylori infection,carcinogenesis,metabolic dysfunction and inflammation as well.

Prevalence of Metabolic Syndrome and Its Associations with Other Metabolic Disorders and Cardiovascular Changes in Health Examination Population in Beijing

Objective To investigate the prevalence of metabolic syndrome(MS) and its associations with other metabolic disorders and cardiovascular changes in health examination population in Beijing.Methods Totally,10 916 individuals who received health examination in Health Examination Center of Peking Union Medical College Hospital were enrolled.The height,weight,blood pressure,serum levels of triglyceride,high-density lipoprotein cholesterol(HDL-C),and fasting blood glucose were recorded.MS was diagnosed based on the working criteria of Chinese Diabetes Society 2004(CDS2004).Meanwhile,other metabolic disorders,including fatty liver and hyperuricemia,were recorded.The cardiovascular changes were reflected by the reports of electrocardiogram(ECG) ST-T changes and atherosclerosis of retinal arteries.Results The overall prevalence rate of MS was 6.1%(666/10 916) in the population.The prevalence rate of MS in male was much higher than that in female(9.0% vs.2.7%,P=0.000).For individuals with MS,the prevalence rates of fatty liver and hyperuricemia were significantly higher than those without MS,respectively(70.4% vs.35.4%,P=0.000;29.9% vs.17.7%,P=0.000).As for cardiovascular changes,the prevalence rates of ECG ST-T changes and atherosclerosis of retinal arteries were significantly higher in individuals with MS than those without MS,respectively(13.8% vs.11.7%,P=0.012;12.0% vs.6.8%,P=0.000).Conclusions The prevalence of MS in Beijing population is high.The individuals with MS have a higher risk for other metabolic disorders and cardiovascular changes.

Infant with cardiomyopathy: When to suspect inborn errors of metabolism?

Inborn errors of metabolism are identified in 5%-26% of infants and children with cardiomyopathy. Although fatty acid oxidation disorders, lysosomal and glycogen storage disorders and organic acidurias are well-known to be associated with cardiomyopathies, emerging reports suggest that mitochondrial dysfunction and congenital disorders of glycosylation may also account for a proportion of cardiomyopathies. This review article clarifies when primary care physicians and cardiologists should suspect inborn errors of metabolism in a patient with cardiomyopathy, and refer the patient to a metabolic specialist for a further metabolic work up, with specific discussions of "red flags" which should prompt additional evaluation.

Impact of the adherence to medical treatment on the main urinary metabolic disorders in patients with kidney stones

Objective:To assess the effect of the adherence to medical treatment on urinary parameters in the 24-h metabolic study of patients with kidney stones.Methods:A retrospective,longitudinal,descriptive,and observational study was carried out by reviewing the hospital electronic medical record from 2014 to 2018.The adherence to drug treatment was measured 6 months after its initiation,and the numerical values of the metabolic studies were compared.Wilcoxon tests were performed to compare the difference before and after treatment.Results:Ninety patients were evaluated,with 73.3% of adherence.The 180-day overall adherence rate was 61.2% in patients treated with a single drug and 85.4% in patients treated with multiple drugs.There is a statistically significant increase in citrate levels in patients with good adherence in comparison with non-adherent patients(p=0.031 vs.p=0.528).Conclusions:Medical treatment and dietary measures in patients with kidney stones have an initial impact at 6 months on the values of the main urinary metabolic alterations that predispose to calculi formation;the most significant is seen in those patients with adherence to medical treatment for hypocitraturia.
