Quan T, Li R, Gao T. Molecular mechanism of melatonin-mediated mitophagy regulating proline production to ameliorate skin aging. Exp Gerontol 2025; 204:112738.

Abstract
Collagen loss is one of the major contributor to signs of skin aging such as dryness, roughness, and wrinkle formation, which is closely linked to a decline in the amount of proline produced in mitochondria. Melatonin has been shown to improve several clinical signs of skin aging, while the mechanism is unclear. In our study, we found that mitophagy, proline synthesis key enzyme NADK2 and proline and collagen levels were significantly reduced, while oxidative stress levels increased in aging skin, and melatonin supplementation could effectively up-regulate mitophagy level and restore proline synthesis and further improved skin aging. However, proline supplementation could also exert an anti-aging effect, while it had no effect on the mitochondrial dysfunction. Moreover, our study indicated that melatonin enters the cell by binding to the MT1 receptor and then enters the mitochondria via the PEPT1 transporter to exert its mitochondrial protective effects. This study helps to elucidate the mechanism of mitochondrial dysfunction-induced skin aging, and provides new theoretical guidance for revealing the mechanism of skin aging and rationally utilizing endocrine hormones to improve skin aging, which has a broad application prospect.

Abstract
Tendinopathy is a chronic, degenerative disease that has increased prevalence in aged populations, and is characterized by a loss in extracellular matrix (ECM) integrity. Recent work has clearly demonstrated age-related deficits in ECM synthesis with aging, as well as some changes to metabolic activity. Since glucose metabolism is critical to protein synthesis and known to be altered in aging, we sought to investigate if age-related changes in metabolism are linked to changes in ECM remodeling. We used our previously developed flexor tendon explant model to expose young and aged tendon explants to various concentrations of glucose and glutamine supplementation and observe changes in metabolic activity, matrix composition, matrix biosynthesis, and expression of metabolic and ECM genes. We hypothesized that elevated levels of glucose and glutamine would lead to increased ECM remodeling as well as elevated gene expression of their respective pathways in young tendons, with no such effect in aged tendons. Interestingly, we found that glutamine processing is affected by glucose levels with increased expression of key glutamine processing pathways with increased glucose, but this effect was lost with aging. We also observed that ECM remodeling is directly related to both glucose and glutamine processing with altered glycosaminoglycan and collagen synthesis with glucose and glutamine media concentration. Overall, our work reveals that glucose and glutamine are intricately linked for both tenocyte health and ECM homeostasis and that their metabolism could be one of the key drivers of age-related deficiencies in tissue maintenance.

Acta Biomater 2025:S1742-7061(25)00315-0. [PMID: 40318743 DOI: 10.1016/j.actbio.2025.04.062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2024] [Revised: 04/25/2025] [Accepted: 04/30/2025] [Indexed: 05/07/2025]
Abstract
Diabetic foot ulcers (DFUs) are a multifactorial medical problem that require multifaceted approaches for effective healing. Most research on DFU healing has concentrated on promoting wound closure, with less emphasis on the quality of repaired tissue. This is problematic, however, since quality of the repaired tissues can have potential to improve wound healing outcomes and limit re-ulceration. If more functionally active dermis replaces the lost tissue, this can effectively maximize strength, organization, and overall structure of the plantar surface. Additionally, DFUs commonly show multi-strain infection, which further exacerbates the non-healing status of these wounds. Treatment of chronic wounds can be benefitted by application of oxygen and localized infection treatment, both can be achieved via our methacrylated chitosan-based (MACF) hydrogel. A non-healing diabetic infected wound model was used to explore extracellular matrix (ECM) organization, tensile strength, and metabolomic profiles at a 21-day endpoint as a marker for maturation and improved functionality of repaired tissues over normal scar formation. Effective remediation of infection was achieved with 14 days of polyhexamethylene biguanide (PHMB) application with improved wound repair compared to continuous treatment. Prolonged (21 day) application of PHMB showed resulting necrosis, although standard application times for patients with infected wounds can reach up to 28 continuous days. Biaxial mechanical analysis showed improved isotropic strength of infected tissues treated with MACF with PHMB stopped on D14, supported by collagen fiber orientation in second harmonics generation (SHG) imaging. Oxygenating MACF treatments also improved collagen deposition through the enhancement of the hydroxyproline fibrillary collagen synthesis pathway. These structural and mechanical results demonstrate a promising potential treatment for infected diabetic foot ulcers which shows improved dermal functionality. STATEMENT OF SIGNIFICANCE: Diabetic foot ulcers are a multifaceted problem in the medical field exacerbated by infection, with potential for gangrene, lower limb amputation, sepsis, or death. Current treatment regimens include oxygen therapy, physical debridement, and strong antibacterials. However, there is a lack of multi-faceted approaches, which we have designed in our oxygenating chitosan-based hydrogels capable of delivering antibiotics. Treatments currently focus on closure of wounds; however, functionality of regenerated tissues are limited due to fibrotic scar formation. Therefore, we have chosen to focus not only on closure, but also quality of regenerated tissues through mechanical testing and analysis of extracellular matrix composition and organization, with a goal of improving functionality of regenerated tissues.

Synthesis and evaluation of piceatannol derivatives as novel arginase inhibitors with radical scavenging activity and their potential for collagen reduction in dermal fibroblasts. Eur J Med Chem 2025; 287:117376. [PMID: 39952100 DOI: 10.1016/j.ejmech.2025.117376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2024] [Revised: 02/04/2025] [Accepted: 02/05/2025] [Indexed: 02/17/2025]
Abstract
High arginase activity is associated with several pathological conditions, including TGF-β-induced fibrosis, by increasing levels of the proline precursor l-ornithine, thereby promoting collagen biosynthesis and increasing oxidative stress due to nitric oxide synthase (NOS) uncoupling. The natural piceatannol has been shown to have beneficial effects on collagen deposition, fibrosis and oxidative stress. In this study, we present an in-depth structure-activity relationship study on arginase I, which resulted in the thioamide derivative 12a with dual catechol rings that displays potent inhibitory activity with IC₅₀ values of 9 μM and 55 μM for bovine and human arginase I, respectively. Quantum chemical modelling suggested that the sulphur atom in the thioamide group plays a crucial role in binding affinity by forming a stable hydrogen bond within the active site of the enzyme. In addition, compound 12a demonstrated high radical scavenging activity and effectively normalised collagen and procollagen levels at 5 μM in an in vitro cell model of a dermal fibrosis.

Abstract
The Pinophyta family has long been used to protect the skin from oxidation, thanks to the action of molecules such as stilbenes, flavonoids, and lignans, which are particularly concentrated in knotwood. These molecules are of interest from a cosmetic perspective. The present study focuses on four species from larch (Larix decidua Mill.), silver fir (Abies alba Mill.), Norway spruce (Picea abies (L.) H.Karst), and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) knotwood, recovered from byproducts of the wood industry. The molecules are extracted from knotwood and used in vitro on human keratinocytes (HaCaT). Studies quantifying reactive oxygen species (ROS) have demonstrated its ability to eliminate hydroxyl radicals and superoxides. Metabolomic analyses using proton nuclear magnetic resonance (1H NMR) and multivariate statistics (PLS-DA) demonstrated that keratinocytes modulate metabolite expression after treatment with knot extracts. Indeed, our findings indicate an increase in metabolites such as glutathione, glycine, glutamate, sarcosine, taurine, and proline, which are known to reduce intracellular oxidative stress and validate the effect on ROS levels. They also indicate that knotwood extracts may affect membrane balance, collagen formation, and oxidative stress levels. This study highlights the value of metabolomic analysis in the cosmetic industry for a detailed understanding of the mechanisms implemented in a whole cell.

Growth performance, nutrient utilization, gut integrity, short-chain fatty acids, and gene expression in Eimeria-challenged broilers receiving stimbiotics and wheat bran as an additional fiber source. Poult Sci 2025; 104:104877. [PMID: 40101510 PMCID: PMC11964626 DOI: 10.1016/j.psj.2025.104877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2024] [Revised: 01/25/2025] [Accepted: 02/01/2025] [Indexed: 03/20/2025] Open
Abstract
Stimbiotic (STB) supplementation and precise inclusion of dietary fiber (DF) can increase the number of fiber-fermenting microorganisms, enhance growth performance, and increase the cecal concentration of short-chain fatty acids (SCFA), potentially improving overall gut health. 1200 male byproduct-breeder day-old chicks were allocated to six treatments in a randomized complete block design. The treatments were: 1) 0 g/kg wheat bran (WB), no STB, no challenge (NCH); 2) 0 g/kg WB, 0.1 g/kg STB, no challenge (NCH- STB); 3) 0 g/kg WB, no STB, with challenge (CH); 4) 50 g/kg WB, no STB, with challenge (CH-WB) 5) 0 g/kg WB, 0.1 g/kg STB and with challenge (CH-STB); 6) 50 g/kg WB, 0.1 g/kg STB plus the challenge (CH-WB-STB). On d13, birds were inoculated with a solution containing E. tenella, E. maxima, and E. acervulina. Data were analyzed by one-way ANOVA, and Tukey HSD was used to separate the means. During the starter phase, weight gain (WG) was greater (P < 0.05), and FCR was lower (P < 0.05) in the WB compared with the control and STB groups. Birds in NCH and NCH-STB treatments had higher (P < 0.05) WG during the acute, whole challenge, grower, and overall phases. Dry matter digestibility (DMD) was higher (P < 0.05) for NCH-STB and CH-STB, and nitrogen (N) digestibility was higher in the CH-WB and CH-WB-STB than in the NCH-STB group. GLUT-1 and CAT-1 were increased (P < 0.05) in the CH-WB than in NCH-STB group. 4EBP1 was increased (P < 0.05) in CH, CH-WB-STB than NCH and NCH-STB groups, and FBXO9 was higher in CH, CH-WB, CH-WB-STB than NCH group. On d42, CH-WB and CH-WB-STB had lower levels (P < 0.05) of isobutyrate and isovalerate than NCH-STB group. In conclusion, neither STB nor WB inclusion influenced growth performance and SCFA profile in Eimeria-challenged birds. Wheat-bran inclusion decreased ceca branched-chain fatty acids (BCFA), which suggests a lower protein fermentation in the ceca, likely as a result of modification of the ceca microbiota.

Abstract
Mitochondria perform essential metabolic processes that sustain cellular bioenergetics and biosynthesis. In a recent article, Ryu et al. explored how mitochondria coordinate biochemical reactions with opposing redox demands within the same cell. They demonstrate that subcellular mitochondrial heterogeneity enables metabolic compartmentalization to permit concurrent oxidative ATP production and reductive proline biosynthesis.

Abstract
Calcium hydroxylapatite (CaHA) is widely used in aesthetics for its dual role as a dermal filler and biostimulator, promoting collagen and elastin synthesis. This study evaluates the comparative potential of CaHA in conventional saline dilution versus CaHA mixed with a poly-micronutrient solution (CaHA/PMN) to enhance its biostimulatory effects. In an in vitro model, primary human fibroblasts were treated with both formulations, and cell viability and gene expression of type I collagen, elastin, FOXO3, SIRT-1, and SIRT-3 were assessed. The results demonstrated that both CaHA and CaHA/PMN treatments significantly improved cellular responses compared to the control. CaHA/PMN outperformed conventional CaHA, with greater increases in cell viability, collagen synthesis, elastin synthesis, and the expression of SIRT-1, SIRT-3, and FOXO3. These findings suggest that poly-micronutrient-enriched solutions can enhance CaHA's regenerative potential, providing a promising approach for skin rejuvenation and elasticity improvement.

Abstract
Heart failure (HF) is a multifaceted clinical syndrome characterized by the heart's inability to pump sufficient blood to meet the body's metabolic demands. It arises from various etiologies, including myocardial injury, hypertension, and valvular heart disease. A critical aspect of HF pathophysiology involves mitochondrial dysfunction, particularly concerning calcium (Ca2+) homeostasis and oxidative stress. This review highlights the pivotal role of excess mitochondrial Ca2+ in exacerbating oxidative stress, contributing significantly to HF progression. Novel insights are provided regarding the mechanisms by which mitochondrial Ca2+ overload leads to increased production of reactive oxygen species (ROS) and impaired cellular function. Despite this understanding, key gaps in research remain, particularly in elucidating the complex interplay between mitochondrial dynamics and oxidative stress across different HF phenotypes. Furthermore, therapeutic strategies targeting mitochondrial dysfunction are still in their infancy, with limited applications in clinical practice. By summarizing recent findings and identifying these critical research gaps, this review aims to pave the way for innovative therapeutic approaches that improve the management of heart failure, ultimately enhancing patient outcomes through targeted interventions.

Abstract
This study employs a comprehensive multi-omics approach to investigate the regulatory roles of specific microRNAs (miRNAs) in Congenital Tooth Agenesis (CTA). A total of 58 miRNAs associated with tooth diseases, cancer, and bone development were initially identified through a literature review and analyzed using bioinformatics. Based on target prediction and network analysis, eight miRNAs with strong connectivity and common target genes were shortlisted for further investigation. Blood samples from 10 CTA patients and 5 healthy controls were analyzed for miRNA expression using stem-loop RT-PCR. Four miRNAs-hsa-miR-218-5p, hsa-miR-15b-5p, hsa-miR-200b-3p, and hsa-let-7a-3p-were identified as significantly differentially expressed, marking their first reported involvement in CTA. Notably, hsa-miR-218-5p and hsa-let-7a-3p emerged as novel regulators with no prior associations with CTA or tooth development. To address the limitations of a small sample size, a multi-omics strategy was employed to validate these findings, integrating miRNA expression data with whole exome sequencing (WES), gene expression panels, and metabolomic profiling. The analysis confirmed the association of these four miRNAs with CTA and highlighted their involvement in critical biological pathways such as Wnt signaling, FGF signaling, and PI3 kinase pathways, which are essential for cellular proliferation, differentiation, and tissue morphogenesis. Importantly, the identification of these miRNAs in blood samples, rather than traditional dental tissues, highlights a minimally invasive approach that could aid in the early detection, therapeutic targeting, and personalized management of dental anomalies.

Abstract
Human skin wounds primarily heal through reparative wound healing without pilosebaceous units or other appendages, rather than regenerative wound healing. Hair follicle (HF) regeneration is a significant challenge for skin wound healing. The effects and underlying mechanisms of Isaria cicadae Miquel rice fermentation extract (IMFRE) remain unclear, although it has anti-inflammatory, antioxidant, and reparative effects on oxidative damage in keratinocytes. We assessed the regenerative wound healing ability of IMFRE and its related molecular mechanisms through experimental validation and network pharmacology analysis. Our findings suggest that IMFRE could be an important potential solution for regenerative wound healing of skin hair follicle by utilizing the Hippo pathway regulatory mechanism. KEY POINTS: • IMFRE was found to significantly enhance the wound healing rate of mouse skin. • CK15 and CD34 were significantly increased by high-dose IMFRE intervention. • IMFRE could inhibit EGFR, GPCR, and Integrin expression.

Abstract
Proline is a major substrate in collagen biosynthesis and is required for collagen molecule formations. However, detailed explanations of the molecular basis through which proline functions in collagen biosynthesis have yet to be provided. Thus, genome-wide screening was employed to elucidate these in the pre-osteoblastic MC3T3-E1 and human periodontal ligament fibroblast (hPDLF) cell lines. Indeed, both cell lines represent important sources for collagen biosynthesis and tissue regeneration in the dental region, specifically treating extracellular proline during cultivations. The altered gene expression patterns were identified, and the precise expression patterns were confirmed by microarray. Cell viability and osteogenic differentiation patterns were examined using a range of experimental methods, such as the MTS assay, ALP staining, ARS staining, and collagen (COL)-type1A ELISA. Overall, we revealed a cell line-specific function of exogenous proline in collagen biosynthesis during osteogenic differentiation conditions with the candidate signaling pathways. These putative signaling networks could represent plausible answers to understanding collagen biosynthesis for regenerating connective tissues such as skin, muscle, and bone.

Abstract
The proline amino acid and prolyl residues of peptides/proteins confer unique biological and biochemical properties that motivates the development of proline-selective analysis. The study focuses on one specific class of problem, the detection of single amino acid variants involving proline, and reports a Pro-selective electrochemiluminescence (ECL) method. To develop this method, the A1-/A2- variants of milk's β-casein protein are investigated because it is a well-established example and abundant samples are readily available. Specifically, β-casein has 209 amino acids with 34 (or 35) proline residues: the A1-variant has a Pro-to-His substitution at position 67 (relative to the A2 variant). The study shows that proline's strong luminescence allows the generic discrimination of: Pro from other amino acids; an A2-oligopeptide from an A1-oligopeptide; the A2-β-casein variant from the A1-variant; and commercially-available A2 milks from A1-containing regular milks. The evidence indicates that luminescence depends on proline content and accessibility, as well as signal quenching. Compared to conventional immunoassays, the ECL method is simple, rapid, and inexpensive. Further, the ECL-method is Pro-selective (vs molecularly-selective like typical immunoassays) which should make it broadly useful for studying the role of proline in biology and especially useful for tracking the digestion of proline-rich proteins in the diet.

Abstract
Tendinopathy is an age-associated degenerative disease characterized by a loss in extracellular matrix (ECM). Since glucose and glutamine metabolism is critical to amino acid synthesis and known to be altered in aging, we sought to investigate if age-related changes in metabolism are linked to changes in ECM remodeling. We exposed young and aged tendon explants to various concentrations of glucose and glutamine to observe changes in metabolic processing (enzyme levels, gene expression, etc.) and matrix biosynthesis. Interestingly, we found that glutamine processing is affected by glucose levels, but this effect was lost with aging. ECM synthesis was altered in a protein-dependent manner by increased glucose and glutamine levels in young tendons. However, these changes were not conserved in aged tendons. Overall, our work suggests that glucose and glutamine metabolism is important for ECM homeostasis, and age-related changes in nutrient metabolism could be a key driver of tendon degeneration.

Abstract
Metabolic dysregulation, including perturbed glutamine-glutamate homeostasis, is common among patients with cardiovascular diseases, but the underlying mechanisms remain largely unknown. Using the human MESA cohort, here we show that plasma glutamine-glutamate ratio is an independent risk factor for carotid plaque progression. Mice deficient in glutaminase-2 (Gls2), the enzyme that mediates hepatic glutaminolysis, developed accelerated atherosclerosis and susceptibility to catastrophic cardiac events, while Gls2 overexpression partially protected from disease progression. High-throughput transcriptional profiling and high-resolution structural biology imaging of aortas showed that Gls2 deficiency perturbed extracellular matrix composition and increased vessel stiffness. This results from an imbalance of glutamine- and glutamate-dependent cross-linked proteins within atherosclerotic lesions and cellular remodeling of plaques. Thus, hepatic glutaminolysis functions as a potent regulator of glutamine homeostasis, which affects the aortic wall structure during atherosclerotic plaque progression.

Abstract
Liquid-jet photoelectron spectroscopy (LJ-PES) and electronic-structure theory were employed to investigate the chemical and structural properties of the amino acid l-proline in aqueous solution for its three ionized states (protonated, zwitterionic, and deprotonated). This is the first PES study of this amino acid in its biologically relevant environment. Proline's structure in the aqueous phase under neutral conditions is zwitterionic, distinctly different from the nonionic neutral form in the gas phase. By analyzing the carbon 1s and nitrogen 1s core levels as well as the valence spectra of aqueous-phase proline, we found that the electronic structure is dominated by the protonation state of each constituent molecular site (the carboxyl and amine groups) with small yet noticeable interference across the molecule. The site-specific nature of the core-level spectra enables the probing of individual molecular constituents. The valence photoelectron spectra are more difficult to interpret because of the overlapping signals of proline with the solvent and pH-adjusting agents (HCl and NaOH). Yet, we are able to reveal subtle effects of specific (hydrogen-bonding) interaction with the solvent on the electronic structure. We also demonstrate that the relevant conformational space is much smaller for aqueous-phase proline than for its gas-phase analogue. This study suggests that caution must be taken when comparing photoelectron spectra for gaseous- and aqueous-phase molecules, particularly if those molecules are readily protonated/deprotonated in solution.

Abstract
Pesticide toxicity is a global concern for honeybee populations, and understanding these effects at the molecular level is critical. This study analyzed the transcriptome of honeybees at larval and adult stages after chronic exposure to a sublethal dose (0.0017 µg a.i./larva) of spinetoram (SPI) during the larval phase. Four groups were used: acetone-treated honeybee larvae (ATL), acetone-treated honeybee adults (ATAs), SPI-treated honeybee larvae (STL), and SPI-treated honeybee adults (STAs). In total, 5719 differentially expressed genes (DEGs) were identified for ATL vs. ATAs, 5754 for STL vs. STAs, 273 for ATL vs. STL, and 203 for ATAs vs. STAs (FC ≤ 1.5, p < 0.05). In response to SPI, 29 unique DEGs were identified in larvae and 42 in adults, with 23 overlapping between comparisons, suggesting genes linked to SPI toxicity. Gene ontology analysis showed that SPI affected metabolism-related genes in larvae and lipid-transport-associated genes in adults. KEGG pathway analysis revealed an enrichment of pathways predominantly associated with metabolism, hormone biosynthesis, and motor proteins in STL. The transcriptomic data were validated by qPCR. These findings demonstrated that SPI disrupts essential molecular processes, potentially harming honeybee development and behavior, underscoring the need for safer agricultural practices.

Abstract
Enchondromas are a common tumor in bone that can occur as multiple lesions in enchondromatosis, which is associated with deformity of the affected bone. These lesions harbor somatic mutations in IDH and driving expression of a mutant Idh1 in Col2 expressing cells in mice causes an enchondromatosis phenotype. Here we compared growth plates from E18.5 mice expressing a mutant Idh1 with control littermates using single cell RNA sequencing. Data from Col2 expressing cells were analysed using UMAP and RNA pseudo-time analyses. A unique cluster of cells was identified in the mutant growth plates that expressed genes known to be upregulated in enchondromas. There was also a cluster of cells that was underrepresented in the mutant growth plates that expressed genes known to be important in longitudinal bone growth. Immunofluorescence showed that the genes from the unique cluster identified in the mutant growth plates were expressed in multiple growth plate anatomic zones, and pseudo-time analysis also suggested these cells could arise from multiple growth plate chondrocyte subpopulations. This data supports the notion that a subpopulation of chondrocytes become enchondromas at the expense of contributing to longitudinal growth.

[PMID: 38838622 DOI: 10.1016/j.foodchem.2024.139917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Revised: 05/19/2024] [Accepted: 05/28/2024] [Indexed: 06/07/2024]
Abstract
Crocus sativus L. is a both medicinal and food bulbous flower whose qualities are geographically characterized. However, identification involving different places of origin of such substances is currently limited to single-omics mediated content analysis. Integrated metabolomics and proteomics, 840 saffron samples from six countries (Spain, Greece, Iran, China, Japan, and India) were analyzed using the QuEChERS extraction method. A total of 77 differential metabolites and 14 differential proteins were identified. The limits of detection of the method were 1.33 to 8.33 μg kg-1, and the recoveries were 85.56% to 105.18%. Using homology modeling and molecular docking, the Gln84, Lys195, Val182 and Pro184 sites of Crocetin glucosyltransferase 2 were found to be the targets of crocetin binding. By multivariate statistical analysis (PCA and PLS-DA), different saffron samples were clearly distinguished. The results provided the basis for the selection and identification of high quality saffron from different producing areas.

Stem Cell Res Ther 2024; 15:346. [PMID: 39380092 PMCID: PMC11462665 DOI: 10.1186/s13287-024-03967-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Accepted: 09/29/2024] [Indexed: 10/10/2024] Open
Abstract
BACKGROUND The metabolic patterns of human placental-derived mesenchymal stem cell (hP-MSC) treatment for primary sclerosing cholangitis (PSC) remain unclear, and therapeutic effects significantly vary due to individual differences. Therefore, it is crucial to investigate the serological response to hP-MSC transplantation through small molecular metabolites and identify easily detectable markers for efficacy evaluation. METHODS Using Mdr2-/- mice as a PSC model and Mdr2+/+ mice as controls, the efficacy of hP-MSC treatment was assessed based on liver pathology, liver enzymes, and inflammatory factors. Serum samples were collected for 12C-/13C-dansylation and DmPA labeling LC-MS analysis to investigate changes in metabolic pathways after hP-MSC treatment. Key metabolites and regulatory enzymes were validated by qRT-PCR and Western blotting. Potential biomarkers of hP-MSC efficacy were identified through correlation analysis and machine learning. RESULTS Collectively, the results of the liver histology, serum liver enzyme levels, and inflammatory factors supported the therapeutic efficacy of hP-MSC treatment. Based on significant differences, 41 differentially expressed metabolites were initially identified; these were enriched in bile acid, lipid, and hydroxyproline metabolism. After treatment, bile acid transport was accelerated, whereas bile acid production was reduced; unsaturated fatty acid synthesis was upregulated overall, with increased FADS2 and elongase expression and enhanced fatty acid β-oxidation; hepatic proline 4-hydroxylase expression was decreased, leading to reduced hydroxyproline production. Correlation analysis of liver enzymes and metabolites, combined with time trends, identified eight potential biomarkers: 2-aminomuconate semialdehyde, L-1-pyrroline-3-hydroxy-5-carboxylic acid, L-isoglutamine, and maleamic acid were more abundant in model mice but decreased after hP-MSC treatment. Conversely, 15-methylpalmitic, eicosenoic, nonadecanoic, and octadecanoic acids were less abundant in model mice but increased after hP-MSC treatment. CONCLUSIONS This study revealed metabolic regulatory changes in PSC model mice after hP-MSC treatment and identified eight promising biomarkers, providing preclinical evidence to support therapeutic applications of hP-MSC.

Abstract
A major risk associated with surgery, including bone tissue procedures, is surgical site infection. It is one of the most common as well as the most serious complications of modern surgery. A helpful countermeasure against infection is antibiotic therapy. In the present study, a methodology has been developed to obtain clindamycin-modified polymer-ceramic hybrid composite coatings for potential use in bone regenerative therapy. The coatings were prepared using a UV-light photocrosslinking method, and the drug was bound to a polymeric and/or ceramic phase. The sorption capacity of the materials in PBS was evaluated by determining the swelling ability and equilibrium swelling. The influence of the presence of ceramics on the amount of liquid bound was demonstrated. The results were correlated with the rate of drug release measured by high-performance liquid chromatography (HPLC). Coatings with higher sorption capacity released the drug more rapidly. Scanning electron microscopy (SEM) imaging was carried out comparing the surface area of the coatings before and after immersion in PBS, and the proportions of the various elements were also determined using the EDS technique. Changes in surface waviness were observed, and chlorine ions were also determined in the samples before incubation. This proves the presence of the drug in the material. The in vitro tests conducted indicated the release of the drug from the biomaterials. The antimicrobial efficacy of the coatings was tested against Staphylococcus aureus. The most promising material was tested for cytocompatibility (MTT reduction assay) against the mouse fibroblast cell line L929 as well as human osteoblast cells hFOB. It was demonstrated that the coating did not exhibit cytotoxicity. Overall, the results signaled the potential use of the developed polymer-ceramic hybrid coatings as drug carriers for the controlled delivery of clindamycin in bone applications. The studies conducted were the basis for directing samples for further in vivo experiments determining clinical efficacy.

[PMID: 39047907 PMCID: PMC11344013 DOI: 10.1016/j.molmet.2024.101995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2024] [Accepted: 07/15/2024] [Indexed: 07/27/2024] Open
Abstract
OBJECTIVES Mutations in Tissue Inhibitor of Metalloproteinases 3 (TIMP3) cause Sorsby's Fundus Dystrophy (SFD), a dominantly inherited, rare form of macular degeneration that results in vision loss. TIMP3 is synthesized primarily by retinal pigment epithelial (RPE) cells, which constitute the outer blood-retinal barrier. One major function of RPE is the synthesis and transport of vital nutrients, such as glucose, to the retina. Recently, metabolic dysfunction in RPE cells has emerged as an important contributing factor in retinal degenerations. We set out to determine if RPE metabolic dysfunction was contributing to SFD pathogenesis. METHODS Quantitative proteomics was conducted on RPE of mice expressing the S179C variant of TIMP3, known to be causative of SFD in humans. Proteins found to be differentially expressed (P < 0.05) were analyzed using statistical overrepresentation analysis to determine enriched pathways, processes, and protein classes using g:profiler and PANTHER Gene Ontology. We examined the effects of mutant TIMP3 on RPE metabolism using human ARPE-19 cells expressing mutant S179C TIMP3 and patient-derived induced pluripotent stem cell-derived RPE (iRPE) carrying the S204C TIMP3 mutation. RPE metabolism was directly probed using isotopic tracing coupled with GC/MS analysis. Steady state [U-13C6] glucose isotopic tracing was preliminarily conducted on S179C ARPE-19 followed by [U-13C6] glucose and [U-13C5] glutamine isotopic tracing in SFD iRPE cells. RESULTS Quantitative proteomics and enrichment analysis conducted on RPE of mice expressing mutant S179C TIMP3 identified differentially expressed proteins that were enriched for metabolism-related pathways and processes. Notably these results highlighted dysregulated glycolysis and glucose metabolism. Stable isotope tracing experiments with [U-13C6] glucose demonstrated enhanced glucose utilization and glycolytic activity in S179C TIMP3 APRE-19 cells. Similarly, [U-13C6] glucose tracing in SFD iRPE revealed increased glucose contribution to glycolysis and the TCA cycle. Additionally, [U-13C5] glutamine tracing found evidence of altered malic enzyme activity. CONCLUSIONS This study provides important information on the dysregulation of RPE glucose metabolism in SFD and implicates a potential commonality with other retinal degenerative diseases, emphasizing RPE cellular metabolism as a therapeutic target.

Abstract
BACKGROUND Fibrotic interstitial lung disease is often identified late due to non-specific symptoms, inadequate access to specialist care, and clinical unawareness precluding proper and timely treatment. Biopsy histological analysis is definitive but rarely performed due to its invasiveness. Diagnosis typically relies on high-resolution computed tomography, while disease progression is evaluated via frequent pulmonary function testing. This study tested the hypothesis that pulmonary fibrosis diagnosis and progression could be non-invasively and accurately evaluated from the hair metabolome, with the longer-term goal to minimize patient discomfort. METHODS Hair specimens collected from pulmonary fibrosis patients (n = 56) and healthy subjects (n = 14) were processed for metabolite extraction using 2DLC/MS-MS, and data were analyzed via machine learning. Metabolomic data were used to train machine learning classification models tuned via a rigorous combination of cross validation, feature selection, and testing with a hold-out dataset to evaluate classifications of diseased vs. healthy subjects and stable vs. progressed disease. RESULTS Prediction of pulmonary fibrosis vs. healthy achieved AUROCTRAIN = 0.888 (0.794-0.982) and AUROCTEST = 0.908, while prediction of stable vs. progressed disease achieved AUROCTRAIN = 0.833 (0.784 - 0.882) and AUROCTEST = 0. 799. Top metabolites for diagnosis included ornithine, 4-(methylnitrosamino)-1-3-pyridyl-N-oxide-1-butanol, Thr-Phe, desthiobiotin, and proline. Top metabolites for progression included azelaic acid, Thr-Phe, Ala-Tyr, indoleacetyl glutamic acid, and cytidine. CONCLUSION This study provides novel evidence that pulmonary fibrosis diagnosis and progression may in principle be evaluated from the hair metabolome. Longer term, this approach may facilitate non-invasive and accurate detection and monitoring of fibrotic lung diseases.

Abstract
Staphylococcus aureus is a pulmonary pathogen associated with substantial human morbidity and mortality. As vaccines targeting virulence determinants have failed to be protective in humans, other factors are likely involved in pathogenesis. Here we analysed transcriptomic responses of human clinical isolates of S. aureus from initial and chronic infections. We observed upregulated collagenase and proline transporter gene expression in chronic infection isolates. Metabolomics of bronchiolar lavage fluid and fibroblast infection, growth assays and analysis of bacterial mutant strains showed that airway fibroblasts produce collagen during S. aureus infection. Host-adapted bacteria upregulate collagenase, which degrades collagen and releases proline. S. aureus then imports proline, which fuels oxidative metabolism via the tricarboxylic acid cycle. Proline metabolism provides host-adapted S. aureus with a metabolic benefit enabling out-competition of non-adapted strains. These data suggest that clinical settings characterized by airway repair processes and fibrosis provide a milieu that promotes S. aureus adaptation and supports infection.

Abstract
Metabolomics significantly impacts drug discovery and precise disease management. This study meticulously assesses the metabolite profiles of cells treated with Crocin, Dexamethasone, and mesenchymal stem cells (MSCs) under oxidative stress induced by 2-chloroethyl ethyl sulfide (CEES). Gas chromatography/mass spectrometry (GC/MS) analysis unequivocally identified substantial changes in 37 metabolites across the treated groups. Notably, pronounced alterations were observed in pathways associated with aminoacyl-tRNA biosynthesis and the metabolism of aspartate, serine, proline, and glutamate. These findings demonstrate the potent capacity of the analyzed treatments to effectively reduce inflammation, mitigate reactive oxygen species production, and enhance cell survival rates. SIGNIFICANCE.

Abstract
Leishmania is an intracellular protozoan transmitted by sand fly vectors; it causes cutaneous, mucocutaneous, or visceral disease. Its growth and survival are impeded by type 1 T helper cell responses, which entail interferon (IFN)-γ-mediated macrophage activation. Leishmania partially escapes this host defense by triggering immune cell and cytokine responses that favor parasite replication rather than killing. Novel methods for in situ analyses have revealed that the pathways of immune control and microbial evasion are strongly influenced by the tissue context, the micro milieu factors, and the metabolism at the site of infection, which we collectively term the 'immunomicrotope'. Understanding the components and the impact of the immunomicrotope will enable the development of novel strategies for the treatment of chronic leishmaniasis.

[PMID: 38964153 DOI: 10.1016/j.phymed.2024.155838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 06/12/2024] [Accepted: 06/20/2024] [Indexed: 07/06/2024]
Abstract
BACKGROUND Areca nut polyphenols (AP) that extracted from areca nut, have been demonstrated for their potential of anti-fatigue effects. However, the underlying mechanisms for the anti-fatigue properties of AP has not been fully elucidated to date. Previous studies have predominantly concentrated on single aspects, such as antioxidation and anti-inflammation, yet have lacked comprehensive multi-dimensional analyses. PURPOSE To explore the underlying mechanism of AP in exerting anti-fatigue effects. METHODS In this study, we developed a chronic sleep deprivation-induced fatigue model and used physiological, hematological, and biochemical indicators to evaluate the anti- fatigue efficacy of AP. Additionally, a multi-omics approach was employed to reveal the anti-fatigue mechanisms of AP from the perspective of microbiome, metabolome, and proteome. RESULTS The detection of physiology, hematology and biochemistry index indicated that AP markedly alleviate mice fatigue state induced by sleep deprivation. The 16S rRNA sequencing showed the AP promoted the abundance of probiotics (Odoribacter, Dubosiella, Marvinbryantia, and Eubacterium) and suppressed harmful bacteria (Ruminococcus). On the other hand, AP was found to regulate the expression of colonic proteins, such as increases of adenosine triphosphate (ATP) synthesis and mitochondrial function related proteins, including ATP5A1, ATP5O, ATP5L, ATP5H, NDUFA, NDUFB, NDUFS, and NDUFV. Serum metabolomic analysis revealed AP upregulated the levels of anti-fatigue amino acids, such as taurine, leucine, arginine, glutamine, lysine, and l-proline. Hepatic proteins express levels, especially tricarboxylic acid (TCA) cycle (CS, SDHB, MDH2, and DLST) and redox-related proteins (SOD1, SOD2, GPX4, and PRDX3), were significantly recovered by AP administration. Spearman correlation analysis uncovered the strong correlation between microbiome, metabolome and proteome, suggesting the anti-fatigue effects of AP is attribute to the energy homeostasis and redox balance through gut-liver axis. CONCLUSION AP increased colonic ATP production and improve mitochondrial function by regulating gut microbiota, and further upregulated anti-fatigue amino acid levels in the blood. Based on the gut-liver axis, AP upregulated the hepatic tricarboxylic acid cycle and oxidoreductase-related protein expression, regulating energy homeostasis and redox balance, and ultimately exerting anti-fatigue effects. This study provides insights into the anti-fatigue mechanisms of AP, highlighting its potential as a therapeutic agent.

Abstract
Detecting and quantifying amino acids is vital in biochemical analyses, especially for diagnosing metabolic disorders. L-proline, among these amino acids, holds significant relevance for various metabolic disorders in living organisms, particularly in humans. hyperprolinemia arises when ineffective breakdown of L-proline occurs due to enzyme deficiencies, leading to its accumulation in the body and underscoring the need for precise monitoring. To address this challenge, molecular imprinting offers a reliable single-step technique for detecting target molecules like proteins, peptides, amino acids, or ions with high selectivity. Moreover, nanoparticles, with significant surface area-to-volume ratios, enable high-level mass transfer and binding kinetics, making them ideal for nano-scale sensitive applications. In this study, 2-hydroxyethyl methacrylate-based molecularly imprinted nanoparticles were synthesized via mini-emulsion polymerization, combining the advantages of molecular imprinting technique and nanoparticles for the specific recognition of L-proline, and were well-characterized by Scanning Electron Microscopy, zeta-sizer particle size analysis, and Fourier Transform Infrared Spectroscopy. Based on zeta-sizer analysis, the estimated diameters of L-proline-imprinted and non-imprinted nanoparticles (Pro-MIPs and NIPs) were determined to be approximately 27.51 nm and 20.66 nm, respectively. The adsorption of L-proline onto nanoparticles from aqueous solutions was investigated in a batch system, and the maximum L-proline adsorption capacity was determined to be 26.58 mg/g for Pro-MIPs and 4.65 mg/g for and NIPs. The selectivity of Pro-MIPs was assessed using Liquid Chromatography-Tandem Mass Spectrometry, even in human serum and in the presence of competing molecules (L-histidine and L-phenylalanine). Additionally, Pro-MIPs maintained their adsorption capacity through up to 10 adsorption-desorption cycles without significant decrease.

Abstract
The article delves into the pathogenesis of systemic sclerosis (SSc) with an emphasis on immunometabolism dysfunctions. SSc is a complex autoimmune connective tissue disorder with skin and organ fibrosis manifestation, vasculopathy, and immune dysregulation. A growing amount of research indicates that immunometabolism plays a significant role in the pathogenesis of autoimmune diseases, including SSc. The review explores the intricate interplay between immune dysfunction and metabolic alterations, focusing on the metabolism of glucose, lipids, amino acids, the TCA (tricarboxylic acid) cycle, and oxidative stress in SSc disease. According to recent research, there are changes in various metabolic pathways that could trigger or perpetuate the SSc disease. Glycolysis and TCA pathways play a pivotal role in SSc pathogenesis through inducing fibrosis. Dysregulated fatty acid β-oxidation (FAO) and consequent lipid metabolism result in dysregulated extracellular matrix (ECM) breakdown and fibrosis induction. The altered metabolism of amino acids can significantly be involved in SSc pathogenesis through various mechanisms. Reactive oxygen species (ROS) production has a crucial role in tissue damage in SSc patients. Indeed, immunometabolism involvement in SSc is highlighted, which offers potential therapeutic avenues. The article underscores the need for comprehensive studies to unravel the multifaceted mechanisms driving SSc pathogenesis and progression.

Abstract
BACKGROUND Eyelash serums, both prescription and over-the-counter, are gaining popularity for enhancing the appearance of eyelashes through various biologically active molecules. Categorized into prostaglandin analogs and non-prostaglandin analogs, these serums claim increased strength, length, luster, and thickness. Current United States law also requires no efficacy or safety assessments by the Food and Drug Administration before approving products for consumer use, potentially posing health risks for patients seeking over-the-counter eyelash enhancements. AIMS Our aims include exploring proposed benefits and adverse effects associated with eyelash serums, while providing evidence-based clinical recommendations on their use. We aim to contribute valuable insights to the understanding of eyelash serums and their respective safety considerations. METHODS The authors conducted a comprehensive electronic search across databases including PubMed, Embase, Cochrane Central, and Google Scholar to evaluate eyelash serum ingredients. Articles were evaluated by two independent researchers for relevance, and the ingredients discussed were analyzed and given clinical recommendations for eyelash serums based off the Oxford Centre for Evidence-Based Medicine. RESULTS Results highlight bimatoprost's efficacy, supported by numerous studies evaluating safety and adverse effects. Other prostaglandin ingredients show potential benefits, but further studies are encouraged to enhance the understanding of respective safety profiles. While non-prostaglandins ingredients show promising data, more studies are needed due to a lack of formal evidence in eyelash serum use. CONCLUSION As the cosmeceutical market for eyelash serums is growing, dermatologists need to be knowledgeable about evidence-based information regarding prescription and over-the-counter eyelash serum products before making recommendations to patients.

Abstract
Intradermal injection of bioactive compounds is used to reduce the effects of aging skin. The aim of this work is to study the response of facial injection of a hyaluronic acid complex supplemented with amino acids and antioxidant vitamins on skin rejuvenation. A total of 40 healthy adult subjects were recruited to whom this complex was injected into the facial skin, three consecutive times every two weeks. Together with assessing the degree of skin hydration, the level of skin microcirculation, wrinkles, skin color, and skin biomechanical parameters were evaluated. Using the GAIS scale, the degree of satisfaction of the participants was assessed. At 42 days (D42), there was an 11-12% increase in skin hydration and viscoelasticity, a 23% increase in skin density, a 27% increase in skin microcirculation, and a significant lightening and whitening of skin color, but without causing changes in skin wrinkles. A value between 1 and 3 on the GAIS scale was observed between 70 and 92% of the participants, and 87% of subjects found their skin more beautiful, 85% would recommend this treatment, and more than 50% found their face rejuvenated. In summary, the intradermal treatment tested suggests skin rejuvenation, with a good degree of safety.

Abstract
Cadmium (Cd) is a toxic heavy metal that causes nephrosis, including acute kidney injury. To prevent and treat acute kidney injury (AKI) following Cd exposure, a tripeptide, Ser-Arg-Pro (SRP), from Sipunculus nudus L. was employed, and its potential efficacy in AKI was assessed. Oral administration of SRP significantly alleviated Cd-induced kidney damage, leading to improved renal function and the attenuation of structural abnormalities. A network pharmacology analysis revealed the potential of SRP in renal protection by targeting various pathways, including mitogen-activated protein kinase (MAPK) signaling, inflammatory response, and apoptosis pathways. Mechanistic studies indicated that SRP achieves renal protection by inhibiting the activation of MAPK pathways (phosphorylation of p38, p56, ERK, and JNK) in the oxidative stress cascade, suppressing inflammatory responses (iNOS, Arg1, Cox2, TNF-α, IL-1β, and IL-6), and restoring altered apoptosis factors (caspase-9, caspase-3, Bax, and Bcl-2). Hence, SRP has the potential to be used as a therapeutic agent for the treatment of Cd-induced nephrotoxicity.

Abstract
Enchondromas are a common tumor in bone that can occur as multiple lesions in enchondromatosis, which is associated with deformity of the effected bone. These lesions harbor mutations in IDH and driving expression of a mutant Idh1 in Col2 expressing cells in mice causes an enchondromatosis phenotype. In this study we compared growth plates from E18.5 mice expressing a mutant Idh1 with control littermates using single cell RNA sequencing. Data from Col2 expressing cells were analyzed using UMAP and RNA pseudo-time analyses. A unique cluster of cells was identified in the mutant growth plates that expressed genes known to be upregulated in enchondromas. There was also a cluster of cells that was underrepresented in the mutant growth plates that expressed genes known to be important in longitudinal bone growth. Immunofluorescence showed that the genes from the unique cluster identified in the mutant growth plates were expressed in multiple growth plate anatomic zones, and pseudo-time analysis also suggested these cells could arise from multiple growth plate chondrocyte subpopulations. This data identifies subpopulations of cells in control and mutant growth plates, and supports the notion that a mutant Idh1 alters the subpopulations of growth plate chondrocytes, resulting a subpopulation of cells that become enchondromas at the expense of other populations that contribute to longitudinal growth.

Abstract
Arsenic exposure is connected with lung toxicity and is related to lung fibrotic changes. Idiopathic pulmonary fibrosis (IPF) is characterized by extracellular matrix (ECM) deposition. Various genetic mechanisms and environmental factors induce or exacerbate pulmonary fibrosis. Collagen synthesis induced by sodium arsenite (NaAsO2) is closely associated with IPF. Fibroblasts tend to fine-tune their metabolic networks to support their synthetic requirements in response to environmental stimuli. Alterations in metabolism have an influential role in the pathogenesis of IPF. However, it is unclear how arsenic affects the metabolism in IPF. The urea cycle (UC) is needed for collagen formation, which provides adequate levels of proline (Pro) for biosynthesis of collagen. Carbamoyl phosphate synthetase 1 (CPS1) converts the ammonia to carbamoyl phosphate, which controls the first reaction of the UC. We show that, in arsenite-exposed mice, high amounts of ammonia in the lung microenvironment promotes the expression levels of CPS1 and the Pro metabolism. Reduction of ammonia and CPS1 ablation inhibit collagen synthesis and ameliorate IPF phenotypes induced by arsenite. This work takes advantage of multi-omics data to enhance understanding of the underlying pathogenic mechanisms, the key molecules and the complicated cellular responses to this pollutant, which provide a target for the prevention of pulmonary fibrosis caused by arsenic.

Abstract
Influenza A virus (IAV) infections pose a global health challenge that necessitates a comprehensive understanding of the host immune response to devise effective therapeutic interventions. As monocytes and macrophages play crucial roles in host defence, inflammation, and repair, this review explores the intricate journey of these cells during and after IAV infection. First, we highlight the dynamics and functions of lung-resident macrophage populations post-IAV. Second, we review the current knowledge of recruited monocytes and monocyte-derived cells, emphasising their roles in viral clearance, inflammation, immunomodulation, and tissue repair. Third, we shed light on the consequences of IAV-induced macrophage alterations on long-term lung immunity. We conclude by underscoring current knowledge gaps and exciting prospects for future research in unravelling the complexities of macrophage responses to respiratory viral infections.

Abstract
Bone is increasingly recognized as a target for diabetic complications. In order to evaluate the direct effects of high glucose on bone, we investigated the global transcriptional changes induced by hyperglycemia in osteoblasts in vitro. Rat bone marrow-derived mesenchymal stromal cells were differentiated into osteoblasts for 10 days, and prior to analysis, they were exposed to hyperglycemia (25 mM) for the short-term (1 or 3 days) or long-term (10 days). Genes and pathways regulated by hyperglycemia were identified using mRNA sequencing and verified with qPCR. Genes upregulated by 1-day hyperglycemia were, for example, related to extracellular matrix organization, collagen synthesis and bone formation. This stimulatory effect was attenuated by 3 days. Long-term exposure impaired osteoblast viability, and downregulated, for example, extracellular matrix organization and lysosomal pathways, and increased intracellular oxidative stress. Interestingly, transcriptional changes by different exposure times were mostly unique and only 89 common genes responding to glucose were identified. In conclusion, short-term hyperglycemia had a stimulatory effect on osteoblasts and bone formation, whereas long-term hyperglycemia had a negative effect on intracellular redox balance, osteoblast viability and function.

Abstract
Fluorosis due to high fluoride levels in drinking water profoundly affects the development of human skeletal and dental structures. Sodium butyrate (NaB) has been found to regulate overall bone mass and prevent pathological bone loss. However, the mechanism of NaB action on fluorosis remains unclear. In this study, a rat model of fluorosis induced by 100 mg/L sodium fluoride was used to investigate the impact of NaB on bone homeostasis and serum metabolomics. It was found that NaB significantly reduced the levels of bone resorption markers CTX-Ⅰ and TRACP-5B in fluorosis rats. Moreover, NaB increased calcium and magnesium levels in bone, while decreasing phosphorus levels. In addition, NaB improved various bone microstructure parameters, including bone mineral density (BMD), trabecular thickness (Tb. Th), trabecular bone separation (Tb. SP), and structural model index (SMI) in the femur. Notably, NaB intervention also enhanced the antioxidant capacity of plasma in fluorosis rats. Furthermore, a comprehensive analysis of serum metabolomics by LC-MS revealed a significant reversal trend of seven biomarkers after the intervention of NaB. Finally, pathway enrichment analysis based on differential metabolites indicated that NaB exerted protective effects on fluorosis by modulating arginine and proline metabolic pathways. These findings suggest that NaB has a beneficial effect on fluorosis and can regulate bone homeostasis by ameliorating metabolic disorders.

Abstract
Plasma metabolomics holds potential for precision medicine, but limited information is available to compare the performance of such methods across multiple cohorts. We compared plasma metabolite profiles after an overnight fast in 11,309 participants of five population-based Swedish cohorts (50-80 years, 52% women). Metabolite profiles were uniformly generated at a core laboratory (Metabolon Inc.) with untargeted liquid chromatography mass spectrometry and a comprehensive reference library. Analysis of a second sample obtained one year later was conducted in a subset. Of 1629 detected metabolites, 1074 (66%) were detected in all cohorts while only 10% were unique to one cohort, most of which were xenobiotics or uncharacterized. The major classes were lipids (28%), xenobiotics (22%), amino acids (14%), and uncharacterized (19%). The most abundant plasma metabolome components were the major dietary fatty acids and amino acids, glucose, lactate and creatinine. Most metabolites displayed a log-normal distribution. Temporal variability was generally similar to clinical chemistry analytes but more pronounced for xenobiotics. Extensive metabolite-metabolite correlations were observed but mainly restricted to within each class. Metabolites were broadly associated with clinical factors, particularly body mass index, sex and renal function. Collectively, our findings inform the conduct and interpretation of metabolite association and precision medicine studies.

Abstract
The effect of Amaranthus cruentus L. seed oil (AmO) on collagen biosynthesis and wound healing was studied in cultured human dermal fibroblasts exposed to UVA radiation. It was found that UVA radiation inhibited collagen biosynthesis, prolidase activity, and expression of the β1-integrin receptor, and phosphorylated ERK1/2 and TGF-β, while increasing the expression of p38 kinase. The AmO at 0.05-0.15% counteracted the above effects induced by UVA radiation in fibroblasts. UVA radiation also induced the expression and nuclear translocation of the pro-inflammatory NF-κB factor and enhanced the COX-2 expression. AmO effectively suppressed the expression of these pro-inflammatory factors induced by UVA radiation. Expressions of β1 integrin and IGF-I receptors were decreased in the fibroblasts exposed to UVA radiation, while AmO counteracted the effects. Furthermore, AmO stimulated the fibroblast's migration in a wound healing model, thus facilitating the repair process following exposure of fibroblasts to UVA radiation. These data suggest the potential of AmO to counteract UVA-induced skin damage.

Synergistic and antagonistic interactions of oxybenzone and ocean acidification: new insight into vulnerable cellular processes in non-calcifying anthozoans. Front Physiol 2024; 14:1332446.

Abstract
Cnidarians face significant threats from ocean acidification (OA) and anthropogenic pollutants such as oxybenzone (BP-3). The convergence of threats from multiple stressors is an important area to investigate because of potential significant synergistic or antagonistic interactions. Real-time quantitative PCR was performed to characterize the expression profiles of twenty-two genes of interest (GOI) in sea anemones (Exaiptasia diaphana) exposed to one of four treatments: 1) 96 h of OA conditions followed by a 4 h exposure to 20 ppb BP-3; 2) Exposure to 4 h 20 ppb BP-3 without 96 h of OA; 3) Exposure to 96 h of OA alone; or 4) laboratory conditions with no exposure to BP-3 and/or OA. These 22 GOIs represent cellular processes associated with proton-dependent transport, sodium-dependent transport, metal cation binding/transport, extracellular matrix, amino acid metabolism/transport, immunity, and/or steroidogenesis. These 22 GOIs provide new insight into vulnerable cellular processes in non-calcifying anthozoans exposed to OA and BP-3. Expression profiles were categorized as synergistic, antagonistic, or additive of BP-3 in the presence of OA. Two GOIs were synergistic. Fifteen GOIs were antagonistic and the remaining five GOIs were additive in response to BP-3 in acidified seawater. A subset of these GOIs appear to be candidate biomarkers for future in situ investigations. In human health, proton-dependent monocarboxylate transporters (MCTs) are promising pharmacological targets and recognized as potential biomarkers. By comparison, these same MCTs appear to be targets of xenobiotic chemical pollutants in cnidarian physiology. In the presence of BP-3, a network of collagen synthesis genes are upregulated and antagonistic in their expression profiles. Cytochrome b561 is a critical protein required for collagen synthesis and in silico modeling demonstrates BP-3 binds in the pocket of cytochrome b561. Understanding the underlying molecular mechanisms of "drug-like" compounds such as BP-3 may lead to a more comprehensive interpretation of transcriptional expression profiles. The collective antagonistic responses of GOIs associated with collagen synthesis strongly suggests these GOIs should be considered candidate biomarkers of effect. GOIs with synergistic and additive responses represent candidate biomarkers of exposure. Results show the effects of OA and BP-3 are interactive with respect to their impact on cnidarians. This investigation offers mechanistic data that supports the expression profiles and underpins higher order physiological responses.

Abstract
Glioblastoma Multiforme (GBM) is a malignant primary brain tumor. Radiotherapy, one of the standard treatments for GBM patients, could induce GBM radioresistance via rewiring cellular metabolism. However, the precise mechanism attributing to GBM radioresistance or targeting strategies to overcome GBM radioresistance are lacking. Here, we demonstrate that SLC25A22, a mitochondrial bi-directional glutamate transporter, is upregulated and showed uni-directionality from mitochondria to cytosol in radioresistant GBM cells, resulting in accumulating cytosolic glutamate. However, mitochondrial glutaminolysis-mediated TCA cycle metabolites and OCR are maintained constantly. The accumulated cytosolic glutamate enhances the glutathione (GSH) production and proline synthesis in radioresistant GBM cells. Increased GSH protects cells against ionizing radiation (IR)-induced reactive oxygen species (ROS) whereas increased proline, a rate-limiting substrate for collagen biosynthesis, induces extracellular matrix (ECM) remodeling, leading to GBM invasive phenotypes. Finally, we discover that genetic inhibition of SLC25A22 using miR-184 mimic decreases GBM radioresistance and aggressiveness both in vitro and in vivo. Collectively, our study suggests that SLC25A22 upregulation confers GBM radioresistance by rewiring glutamate metabolism, and SLC25A22 could be a significant therapeutic target to overcome GBM radioresistance.

Abstract
Intestinal fibrostenosis in patients with Crohn's disease (CD) is a common and untreatable comorbidity that is notoriously difficult to monitor. We aimed to find metabolites associated with the presence of fibrostenosis in patients with CD using targeted and untargeted metabolomics analyses of serum and primary cell cultures using hyphenated ultra-high performance liquid chromatography high-resolution mass spectrometry. Targeted metabolomics revealed 11 discriminating metabolites in serum, which were enriched within the arginine and proline metabolism pathway. Based on untargeted metabolomics and discriminant analysis, 166 components showed a high predictive value. In addition, human intestinal fibroblasts isolated from stenotic tissue were characterized by differential levels of medium-chain dicarboxylic acids, which are proposed as an energy source through beta-oxidation, when oxidative phosphorylation is insufficient. Another energy providing pathway in such situations is anaerobic glycolysis, a theory supported by increased expression of hexokinase 2 and solute carrier family 16 member 1 in stenotic fibroblasts. Of interest, four (unannotated) metabolic components showed a negative correlation with hexokinase 2 gene expression. Together, this study provides a discriminative metabolic fingerprint in the serum and in intestinal fibroblasts of stenotic and non-stenotic patients with CD suggestive for increased production of building blocks for collagen synthesis and increased glycolysis.

Abstract
We report a 10-year-old boy with a de novo pathogenic variant in ALDH18A1, a rare form of metabolic cutis laxa, which was complicated by atlantoaxial instability and spinal cord compression following a fall from standing height. The patient required emergent cervical spine fusion and decompression followed by a 2-month hospitalization and rehabilitation. In addition to the core clinical features of joint and skin laxity, hypotonia, and developmental delays, we expand the connective tissue phenotype by adding a new potential feature of cervical spine instability. Patients with pathogenic variants in ALDH18A1 may warrant cervical spine screening to minimize possible morbidity. Neurosurgeons, geneticists, primary care providers, and families should be aware of the increased risk of severe cervical injury from minor trauma.

Abstract
Accurate diagnosis of dry eye disease (DED) is challenging, and even today there is no gold standard biomarker of DED. Hypothesis-free global metabolomic studies of tears from DED patients have great potential to discover metabolites and pathways affected in the pathophysiology of DED, and to identify possible future biomarkers. These metabolites and biomarkers could be important for diagnosing and monitoring disease as well as for new therapeutic targets and strategies. As DED is associated with dry mouth, this study aimed to perform metabolomic analyses of tears and saliva from patients with decreased tear film break-up time but normal Schirmer test, and age-matched controls with both tear production and stability within physiological range. We applied strict inclusion criteria to reduce sampling bias in the metabolomic analyses and selected only age-matched females with Schirmer test values between 10-15 mm/5 min. The tear film analysis arm included 19 patients (with tear film break-up time 0-5 s) and 12 controls (with tear film break-up time 10-30 s), while the salivary analysis arm consisted of a subset which included 18 patients and six controls. Metabolomic analyses were performed using liquid chromatography and high-resolution mass spectrometry. Analyses using a global database search detected a total of 56 metabolites in tear samples that were significantly different between the groups. Of these, several have known associations with DED. These metabolites are present in meibum and have anti-oxidative characteristics or associations with the ocular microbiome, and altered concentrations suggest that they may play a significant role in DED associated with decreased tear film stability. In saliva, hypotaurine levels were lower among patients with tear film instability. In this pilot study, we found different levels of several metabolites in patients with decreased tear film break-up time that may have associations with DED. Future studies are required to replicate our findings and clarify the exact roles of these metabolites.

Abstract
Bone marrow fibrosis represents an important structural change in the marrow that interferes with some of its normal functions. The aetiopathogenesis of fibrosis is not well established except in its primary form. The present review consolidates current understanding of marrow fibrosis. We searched PubMed without time restriction using key words: bone marrow and fibrosis as the main stem against the terms: growth factors, cytokines and chemokines, morphology, megakaryocytes and platelets, myeloproliferative disorders, myelodysplastic syndrome, collagen biosynthesis, mesenchymal stem cells, vitamins and minerals and hormones, and mechanism of tissue fibrosis. Tissue marrow fibrosis-related papers were short listed and analysed for the review. It emerged that bone marrow fibrosis is the outcome of complex interactions between growth factors, cytokines, chemokines and hormones together with their facilitators and inhibitors. Fibrogenesis is initiated by mobilisation of special immunophenotypic subsets of mesenchymal stem cells in the marrow that transform into fibroblasts. Fibrogenic stimuli may arise from neoplastic haemopoietic or non-hematopoietic cells, as well as immune cells involved in infections and inflammatory conditions. Autoimmunity is involved in a small subset of patients with marrow fibrosis. Megakaryocytes and platelets are either directly involved or are important intermediaries in stimulating mesenchymal stem cells. MMPs, TIMPs, TGF-β, PDGRF, and basic FGF and CRCXL4 chemokines are involved in these processes. Genetic and epigenetic changes underlie many of these conditions.

Abstract
Volatile organic compounds (VOCs) have shown promise as potential biomarkers in idiopathic pulmonary fibrosis. Measuring VOCs in the headspace ofin vitromodels of lung fibrosis may offer a method of determining the origin of those detected in exhaled breath. The aim of this study was to determine the VOCs associated with two lung cell lines (A549 and MRC-5 cells) and changes associated with stimulation of cells with the pro-fibrotic cytokine, transforming growth factor (TGF)-β1. A dynamic headspace sampling method was used to sample the headspace of A549 cells and MRC-5 cells. These were compared to media control samples and to each other to identify VOCs which discriminated between cell lines. Cells were then stimulated with the TGF-β1 and samples were compared between stimulated and unstimulated cells. Samples were analysed using thermal desorption-gas chromatography-mass spectrometry and supervised analysis was performed using sparse partial least squares-discriminant analysis (sPLS-DA). Supervised analysis revealed differential VOC profiles unique to each of the cell lines and from the media control samples. Significant changes in VOC profiles were induced by stimulation of cell lines with TGF-β1. In particular, several terpenoids (isopinocarveol, sativene and 3-carene) were increased in stimulated cells compared to unstimulated cells. VOC profiles differ between lung cell lines and alter in response to pro-fibrotic stimulation. Increased abundance of terpenoids in the headspace of stimulated cells may reflect TGF-β1 cell signalling activity and metabolic reprogramming. This may offer a potential biomarker target in exhaled breath in IPF.

Abstract
TGF-β1, a key fibrotic cytokine, enhances both the expression and translocation of the activating transcriptional factor 4 (ATF4) and activates the serine/glycine biosynthesis pathway, which is crucial for augmenting collagen production. Targeting the TGF-β1-ATF4-serine/glycine biosynthesis pathway might offer a promising therapeutic approach for fibrotic diseases. In this study, we aimed to identify a proline-containing dipeptide in Hibiscus sabdariffa plant cells that modulates collagen synthesis. We induced Hibiscus sabdariffa plant cells and screened for a proline-containing dipeptide that can suppress TGF-β1-induced collagen synthesis in fibroblasts. Analyses were conducted using LC-MS/MS, RT-qPCR, Western blot analysis, and immunocytochemistry. We identified Gly-Pro (GP) from the extract of Hibiscus sabdariffa plant cells as a dipeptide capable of suppressing TGF-β1-induced collagen production. GP inhibited the phosphorylation of Smad2/3 and reduced the expression of ATF4, which is upregulated by TGF-β1. Notably, GP also decreased the expression of enzymes involved in the serine/glycine biosynthesis and glucose metabolism pathways, such as PHGDH, PSAT1, PSPH, SHMT2, and SLC2A1. Our findings indicate that the peptide GP, derived from Hibiscus sabdariffa plant cells, exhibits potent anti-fibrotic effects, potentially through its regulation of the TGF-β1-ATF4-serine/glycine biosynthesis pathway.

Abstract
Proline and its synthesis enzyme pyrroline-5-carboxylate reductase 1 (PYCR1) are implicated in epithelial-mesenchymal transition (EMT), yet how proline and PYCR1 function in allergic asthmatic airway remodeling via EMT has not yet been addressed to our knowledge. In the present study, increased levels of plasma proline and PYCR1 were observed in patients with asthma. Similarly, proline and PYCR1 in lung tissues were high in a murine allergic asthma model induced by house dust mites (HDMs). Pycr1 knockout decreased proline in lung tissues, with reduced airway remodeling and EMT. Mechanistically, loss of Pycr1 restrained HDM-induced EMT by modulating mitochondrial fission, metabolic reprogramming, and the AKT/mTORC1 and WNT3a/β-catenin signaling pathways in airway epithelial cells. Therapeutic inhibition of PYCR1 in wild-type mice disrupted HDM-induced airway inflammation and remodeling. Deprivation of exogenous proline relieved HDM-induced airway remodeling to some extent. Collectively, this study illuminates that proline and PYCR1 involved with airway remodeling in allergic asthma could be viable targets for asthma treatment.

Abstract
The development of liver fibrosis is one of the most severe and life-threatening outcomes of chronic liver disease (CLD). For targeted therapy of CLD, it is highly needed to reveal molecular targets for normalizing metabolic processes impaired in damaged liver and associated with fibrosis. In this study, we investigated the morphological and biochemical changes in rat liver models of fibrosis induced by chronic administration of thioacetamide, carbon tetrachloride, bile duct ligation (BDL), and ischemia/reperfusion (I/R), with a specific focus on carbohydrate and energy metabolism. Changes in the levels of substrates and products, as well as enzyme activities of the major glucose metabolic pathways (glycolysis, glucuronidation, and pentose phosphate pathway) were examined in rat liver tissue after injury. We examined key markers of oxidative energy metabolism, such as the activity of the Krebs cycle enzymes, and assessed mitochondrial respiratory activity. In addition, pro- and anti-oxidative status was assessed in fibrotic liver tissue. We found that 6 weeks of exposure to thioacetamide, carbon tetrachloride, BDL or I/R resulted in a decrease in the activity of glycolytic enzymes, retardation of mitochondrial respiration, elevation of glucuronidation, and activation of pentose phosphate pathways, accompanied by a decrease in antioxidant activity and the onset of oxidative stress in rat liver. Resemblance and differences in the changes in the fibrosis models used are described, including energy metabolism alterations and antioxidant status in the used fibrosis models. The least pronounced changes in glucose metabolism and mitochondrial functions in the I/R and thioacetamide models were associated with the least advanced fibrosis. Ultimately, liver fibrosis significantly altered the metabolic profile in liver tissue and the flux of glucose metabolic pathways, which could be the basis for targeted therapy of liver fibrosis in CLD caused by toxic, cholestatic, or I/R liver injury.
