Cardiovascular disease(CVD)remains one of the leading causes of mortality among adults globally,with continuously rising morbidity and mortality rates.Metabolic disorders are closely linked to various cardiovascular diseases and play a critical role in their pathogenesis and progression,involving multifaceted mechanisms such as altered substrate utilization,mitochondrial structural and functional dysfunction,and impaired ATP synthesis and transport.In recent years,the potential role of peroxisome proliferator-activated receptors(PPARs)in cardiovascular diseases has garnered significant attention,particularly peroxisome proliferator-activated receptor alpha(PPARα),which is recognized as a highly promising therapeutic target for CVD.PPARαregulates cardiovascular physiological and pathological processes through fatty acid metabolism.As a ligand-activated receptor within the nuclear hormone receptor family,PPARαis highly expressed in multiple organs,including skeletal muscle,liver,intestine,kidney,and heart,where it governs the metabolism of diverse substrates.Functioning as a key transcription factor in maintaining metabolic homeostasis and catalyzing or regulating biochemical reactions,PPARαexerts its cardioprotective effects through multiple pathways:modulating lipid metabolism,participating in cardiac energy metabolism,enhancing insulin sensitivity,suppressing inflammatory responses,improving vascular endothelial function,and inhibiting smooth muscle cell proliferation and migration.These mechanisms collectively reduce the risk of cardiovascular disease development.Thus,PPARαplays a pivotal role in various pathological processes via mechanisms such as lipid metabolism regulation,anti-inflammatory actions,and anti-apoptotic effects.PPARαis activated by binding to natural or synthetic lipophilic ligands,including endogenous fatty acids and their derivatives(e.g.,linoleic acid,oleic acid,and arachidonic acid)as well as synthetic peroxisome proliferators.Upon ligand binding,PPARαactivates the nuclear receptor retinoid X receptor(RXR),forming a PPARα-RXR heterodimer.This heterodimer,in conjunction with coactivators,undergoes further activation and subsequently binds to peroxisome proliferator response elements(PPREs),thereby regulating the transcription of target genes critical for lipid and glucose homeostasis.Key genes include fatty acid translocase(FAT/CD36),diacylglycerol acyltransferase(DGAT),carnitine palmitoyltransferase I(CPT1),and glucose transporter(GLUT),which are primarily involved in fatty acid uptake,storage,oxidation,and glucose utilization processes.Advancing research on PPARαas a therapeutic target for cardiovascular diseases has underscored its growing clinical significance.Currently,PPARαactivators/agonists,such as fibrates(e.g.,fenofibrate and bezafibrate)and thiazolidinediones,have been extensively studied in clinical trials for CVD prevention.Traditional PPARαagonists,including fenofibrate and bezafibrate,are widely used in clinical practice to treat hypertriglyceridemia and low high-density lipoprotein cholesterol(HDL-C)levels.These fibrates enhance fatty acid metabolism in the liver and skeletal muscle by activating PPARα,and their cardioprotective effects have been validated in numerous clinical studies.Recent research highlights that fibrates improve insulin resistance,regulate lipid metabolism,correct energy metabolism imbalances,and inhibit the proliferation and migration of vascular smooth muscle and endothelial cells,thereby ameliorating pathological remodeling of the cardiovascular system and reducing blood pressure.Given the substantial attention to PPARα-targeted interventions in both basic research and clinical applications,activating PPARαmay serve as a key therapeutic strategy for managing cardiovascular conditions such as myocardial hypertrophy,atherosclerosis,ischemic cardiomyopathy,myocardial infarction,diabetic cardiomyopathy,and heart failure.This review comprehensively examines the regulatory roles of PPARαin cardiovascular diseases and evaluates its clinical application value,aiming to provide a theoretical foundation for further development and utilization of PPARα-related therapies in CVD treatment. 展开更多

Parkinson’s disease(PD)is a common neurodegenerative disorder with profound impact on patients’quality of life and long-term health,and early detection and intervention are particularly critical.In recent years,the search for precise and reliable biomarkers has become one of the key strategies to effectively address the clinical challenges of PD.In this paper,we systematically evaluated potential biomarkers,including proteins,metabolites,epigenetic markers,and exosomes,in the peripheral blood of PD patients.Protein markers are one of the main directions of biomarker research in PD.In particular,α‑synuclein and its phosphorylated form play a key role in the pathological process of PD.It has been shown that aggregation ofα-synuclein may be associated with pathologic protein deposition in PD and may be a potential marker for early diagnosis of PD.In terms of metabolites,uric acid,as a metabolite,plays an important role in oxidative stress and neuroprotection in PD.It has been found that changes in uric acid levels may be associated with the onset and progression of PD,showing its potential as an early diagnostic marker.Epigenetic markers,such as DNA methylation modifications and miRNAs,have also attracted much attention in Parkinson’s disease research.Changes in these markers may affect the expression of PD-related genes and have an important impact on the onset and progression of the disease,providing new research perspectives for the early diagnosis of PD.In addition,exosomes,as a potential biomarker carrier for PD,are able to carry a variety of biomolecules involved in intercellular communication and pathological regulation.Studies have shown that exosomes may play an important role in the pathogenesis of PD,and their detection in blood may provide a new breakthrough for early diagnosis.It has been shown that exosomes may play an important role in the pathogenesis of PD,and their detection in blood may provide new breakthroughs in early diagnosis.In summary,through in-depth evaluation of biomarkers in the peripheral blood of PD patients,this paper demonstrates the important potential of these markers in the early diagnosis of PD and in the study of pathological mechanisms.Future studies will continue to explore the clinical application value of these biomarkers to promote the early detection of PD and individualized treatment strategies. 展开更多

Objective Repetitive transcranial magnetic stimulation(rTMS)has demonstrated efficacy in enhancing neurocognitive performance in Alzheimer’s disease(AD),but the neurobiological mechanisms linking synaptic pathology,neural oscillatory dynamics,and brain network reorganization remain unclear.This investigation seeks to systematically evaluate the therapeutic potential of rTMS as a non-invasive neuromodulatory intervention through a multimodal framework integrating clinical assessments,molecular profiling,and neurophysiological monitoring.Methods In this prospective double-blind trial,12 AD patients underwent a 14-day protocol of 20 Hz rTMS,with comprehensive multimodal assessments performed pre-and postintervention.Cognitive functioning was quantified using the mini-mental state examination(MMSE)and Montreal cognitive assessment(MOCA),while daily living capacities and neuropsychiatric profiles were respectively evaluated through the activities of daily living(ADL)scale and combined neuropsychiatric inventory(NPI)-Hamilton depression rating scale(HAMD).Peripheral blood biomarkers,specifically Aβ1-40 and phosphorylated tau(p-tau181),were analyzed to investigate the effects of rTMS on molecular metabolism.Spectral power analysis was employed to investigate rTMS-induced modulations of neural rhythms in AD patients,while brain network analyses incorporating topological properties were conducted to examine stimulus-driven network reorganization.Furthermore,systematic assessment of correlations between cognitive scale scores,blood biomarkers,and network characteristics was performed to elucidate cross-modal therapeutic associations.Results Clinically,MMSE and MOCA scores improved significantly(P<0.05).Biomarker showed that Aβ1-40 level increased(P<0.05),contrasting with p-tau181 reduction.Moreover,the levels of Aβ1-40 were positively correlated with MMSE and MOCA scores.Post-intervention analyses revealed significant modulations in oscillatory power,characterized by pronounced reductions in delta(P<0.05)and theta bands(P<0.05),while concurrent enhancements were observed in alpha,beta,and gamma band activities(all P<0.05).Network analysis revealed frequency-specific reorganization:clustering coefficients were significantly decreased in delta,theta,and alpha bands(P<0.05),while global efficiency improvement was exclusively detected in the delta band(P<0.05).The alpha band demonstrated concurrent increases in average nodal degree(P<0.05)and characteristic path length reduction(P<0.05).Further research findings indicate that the changes in the clinical scale HAMD scores before and after rTMS stimulation are negatively correlated with the changes in the blood biomarkers Aβ1-40 and p-tau181.Additionally,the changes in the clinical scales MMSE and MoCA scores were negatively correlated with the changes in the node degree of the alpha frequency band and negatively correlated with the clustering coefficient of the delta frequency band.However,the changes in MMSE scores are positively correlated with the changes in global efficiency of both the delta and alpha frequency bands.Conclusion 20 Hz rTMS targeting dorsolateral prefrontal cortex(DLPFC)significantly improves cognitive function and enhances the metabolic clearance ofβ-amyloid and tau proteins in AD patients.This neurotherapeutic effect is mechanistically associated with rTMS-mediated frequency-selective neuromodulation,which enhances the connectivity of oscillatory networks through improved neuronal synchronization and optimized topological organization of functional brain networks.These findings not only support the efficacy of rTMS as an adjunctive therapy for AD but also underscore the importance of employing multiple assessment methods—including clinical scales,blood biomarkers,and EEG——in understanding and monitoring the progression of AD.This research provides a significant theoretical foundation and empirical evidence for further exploration of rTMS applications in AD treatment. 展开更多

Currently,research on N^(6)-methyladenine(m^(6)A)is extensive in the field of oncology,while studies involving m^(6)A and skin diseases remain relatively limited.Based on existing reports,we searched PubMed and Web of Science for literature related to m^(6)A and dermatological conditions.Analysis of citation counts and journal impact factors revealed a significant upward trend in the volume of m^(6)A-related research.Term frequency analysis of titles and abstracts indicated that studies mainly focus on skin tumors and inflammatory or immune-related skin diseases,particularly melanoma,psoriasis,and skin development.Transcriptomic data from the Gene Expression Omnibus(GEO)were analyzed,revealing differential expression of m^(6)A-related genes in 4 types of skin tumors(including squamous cell carcinoma and basal cell carcinoma)as well as in inflammatory skin diseases such as psoriasis and atopic dermatitis,and potential mechanisms of action were also explored.Findings suggest that m^(6)A modifications exhibit heterogeneity between neoplastic and nonneoplastic skin diseases.However,the regulatory mechanisms of m^(6)A dynamic modifications on key genes involved in dermatological disorders remain unclear and warrant further investigation. 展开更多

Creutzfeldt-Jakob disease(CJD)is a rare neurodegenerative disorder characterized by abnormalities in the prion protein(PrP),the most common form of human prion disease.Although Genome-Wide Association Studies(GWAS)have identified numerous risk genes for CJD,the mechanisms underlying these risk loci remain poorly understood.This study aims to elucidate novel genetically prioritized candidate proteins associated with CJD in the human brain through an integrative analytical pipeline.Utilizing datasets from Protein Quantitative Trait Loci(pQTL)(NpQTL1=152,NpQTL2=376),expression QTL(eQTL)(N=452),and the CJD GWAS(NCJD=4110,NControls=13569),we implemented a systematic analytical pipeline.This pipeline included Proteome-Wide Association Study(PWAS),Mendelian randomization(MR),Bayesian colocalization,and Transcriptome-Wide Association Study(TWAS)to identify novel genetically prioritized candidate proteins implicated in CJD pathogenesis within the brain.Through PWAS,we identified that the altered abundance of six brain proteins was significantly associated with CJD.Two genes,STX6 and PDIA4,were established as lead causal genes for CJD,supported by robust evidence(False Discovery Rate<0.05 in MR analysis;PP4/(PP3+PP4)≥0.75 in Bayesian colocalization).Specifically,elevated levels of STX6 and PDIA4 were associated with an increased risk of CJD.Additionally,TWAS demonstrated that STX6 and PDIA4 were associated with CJD at the transcriptional level. 展开更多

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. 展开更多

Cardiovascular diseases are a group of disorders of the heart and blood vessels,primarily including coronary heart disease,stroke,and other diseases.It is the world’s leading cause of death,and its incidence is increasing yearly.Hypertension is a major risk factor for cardiovascular disease.Wnt signaling comprises a series of highly conservative cascading events controlling fundamental biological processes.Wnt signaling pathways include the canonical Wnt pathway(or Wnt/β-catenin pathway),the non canonical planar cell-polarity pathway,and the non-canonical calcium-dependent pathways.Abnormal Wnt signaling promotes cell proliferation and differentiation,cardiac malformations,various malignancies,so drugs targeting Wnt signaling play a great therapeutic potential.Wnt/β-catenin pathway is involved in the occurrence and development of cardiovascular diseases such as atherosclerosis and stroke by regulating cell proliferation,migration,apoptosis,blood-brain barrier permeability,inflammation,oxidative stress,and immune response.Based on the latest research progress,this review summarizes the role of Wnt/β-catenin signaling in cardiovascular diseases,in order to provide new ideas for the prevention and treatment of cardiovascular diseases. 展开更多
