Caloric restriction mimetics (CRMs) are compounds mimicking CR effects, offering a potential therapeutic avenue for age-related diseases. This study explores the potential protective effects of CR on the brain neocortex (GSE11291) and the identification of CRMs using integrative bioinformatics and systems biology approaches. Our findings indicate that long-term CR activates cellular pathways improving mitochondrial function, enhancing antioxidant capacity, and reducing inflammation, potentially providing neuroprotection. The key signaling pathways enriched in our study include PPAR, mTOR, FoxO, AMPK, and Notch signaling pathways, which are crucial regulators of metabolism, cellular stress response, neuroprotection, and longevity. We identify key signaling molecules and molecular mechanisms associated with CR, including transcription factors, kinase regulators, and microRNAs linked to differentially expressed genes. Furthermore, potential CRMs such as rapamycin, replicating CR-related health benefits, are identified. Additionally, machine learning models were developed to classify small molecules based on their CNS activity and anti-inflammatory properties. As a proof of concept, we have demonstrated the ischemic neuroprotective effects of two top-ranked candidate reference molecules (CRMs) using the oxygen–glucose deprivation (OGD) model, an established in vitro stroke model. However, further investigations are essential to fully elucidate the therapeutic potential of these CRMs. In summary, our study suggests that long-term CR entails protective mechanisms preserving and safeguarding neuronal function, potentially impacting the treatment of age-related neurological diseases. Moreover, our findings contribute to the identification of potential genes and regulatory molecules involved in CR, along with potential CRMs, providing a promising foundation for future research in the field of neurological disorder treatment.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":652,"journal":{"name":"Journal of Molecular Neuroscience","volume":"75 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We previously identified extracellular matrix protein 2 (ECM2) as a potential candidate biomarker for predicting intracranial aneurysm (IA) rupture through iTRAQ combined with LC–MS/MS protein quantification technology, so this study aimed to further validate the ability of plasma ECM2 expression levels to predict IA rupture. This prospective, observational, single-center cohort study enrolled 322 individuals with ruptured intracranial aneurysm (RIA, <i>N</i> = 123), UIA (<i>N</i> = 89), traumatic subarachnoid hemorrhage (tSAH, <i>N</i> = 55), or healthy controls (HC, <i>N</i> = 55). ECM2 plasma levels were quantified using enzyme-linked immunosorbent assay (ELISA). The Spearman rank correlation analysis was employed to examine the relationship between variables. Independent risk factors of sIA rupture were identified using logistic regression analysis. The ROC curve assessed the predictive capability for sIA rupture. Plasma ECM2 was notably higher in RIA patients than in UIA, tSAH, and HC groups. Plasma ECM2 levels showed no significant difference among the asymptomatic UIA, HC, and tSAH groups. There was also no significant difference in plasma ECM2 levels between symptomatic UIA patients and RIA patients. Furthermore, the plasma ECM2 level was closely related to hypertension history in sIA patients. ECM2 plasma level was an independent risk factor for sIA rupture. The plasma ECM2 cutoff level for predicting IA rupture was determined to be 1540.67 pg/ml. The combination of ECM2 levels and aneurysm location increased predictive accuracy (AUC = 0.828, sensitivity 87.0%, specificity 68.8%, accuracy 83.2%), surpassing the performance of PHASES and ELPASS scores.

Additionally, the tissue-specific expression [mean counts per million (CPM) of 5.979] of novel lncRNA, BambuTx1299, in the cerebellar hemisphere was observed.

They originate due to defects in the O-mannosyl glycosylation of α-dystroglycan (α-DG), a prominent linker between the intracellular cytoskeleton and the extracellular matrix (ECM). Fundamentally, such interactions are crucial for the integrity of muscle fibers and neuromuscular synapses, where their defects are mainly associated with muscle and brain dysfunction. To date, biallelic variants in 18 genes have been associated with DGPs, where the underlying cause is still undefined in a significant proportion of patients. Glycosylation of α-DG generates three core motifs where the core M3 is responsible for interaction with the basement membrane. Consistently, all gene defects that corrupt core M3 maturation have been identified as causes of DGPs. <i>POMGNT1</i> which stimulates the generation of core M1 is also associated with DGPs, as it plays a central role in core M3 processing. Other genes involved in the glycosylation of α-DG seem unrelated to DPGs. The current review illustrates the <i>O</i>-mannosylation pathway of α-DG highlighting the functional properties of related genes and their contribution to the progression of DPGs. Different classes of DPGs are also elaborated characterizing the clinical features of each distinct type and phenotypes associated with each single gene.

A cross-sectional survey was conducted in rural China among 994 individuals aged 30 years or older. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). Genetic analysis focused on two single-nucleotide polymorphisms (SNPs) in the autophagy-related gene ATG7 (rs2606757 and rs8154). Plasma concentrations of metals were quantified using inductively coupled plasma mass spectrometry. Restricted cubic splines were used to explore the association between serum metal concentration and the occurrence of mild cognitive impairment in individuals with various genotypes. Bayesian Kernel Machine Regression (BKMR) models were used to explore the interactions between individual metals. In a restricted cubic spline model, there is a nonlinear relationship between plasma concentration of Cd and the occurrence of cognitive impairment in individuals carrying the AA (<i>P</i> of Nonlinear = 0.008) and AT (<i>P</i> of Nonlinear = 0.007) genotypes at the rs2606757.

The TT genotype at rs2606757 in ATG7 appears to confer greater cognitive resilience against Cd-induced cognitive damage.
