Eur J Pharmacol 2025; 994:177388. [PMID: 39971228 DOI: 10.1016/j.ejphar.2025.177388] [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: 08/04/2024] [Revised: 02/09/2025] [Accepted: 02/13/2025] [Indexed: 02/21/2025]
Abstract
Aging can cause age-related diseases such as cancer, cardiovascular and neurodegenerative diseases. Cordycepin exerts anti-oxidation, anti-inflammatory and neuroprotective effects. However, the anti-aging effect of cordycepin is still unclear. This study aimed to investigate the anti-aging effect of cordycepin and unravel the underlying mechanism. Cordycepin prolonged the lifespan of C. elegans under normal and heat stress conditions, without effects on the normal growth and reproduction of C. elegans. Cordycepin also improved the locomotion ability, inhibited the deposition of aging pigment lipofuscin and alleviated the oxidative stress damage by decreasing the excessive accumulation of ROS and raising the antioxidant enzyme activities in C. elegans. The metabolomics study showed that cordycepin changed 19 metabolites including citric acid, linoleic acid, oleic acid, glutamic acid, pyruvic acid and so on. Transcriptomics study revealed that cordycepin up-regulated the gene expression of acox-1.2, acox-1.3, acox-1.4, acs-1, acs-15, acdh-1, acdh-4 and acdh-8 in C. elegans, suggesting that cordycepin prolonged its lifespan via regulating fatty acid degradation, fatty acid metabolism and so on. In summary, the current study demonstrated that cordycepin exerted the anti-aging effect on C. elegans by improving the antioxidant system and regulating the genes involved in fatty acid metabolism to inhibit the accumulation of linoleic acid and oleic acid. Therefore, cordycepin might be a promising agent for aging and age-related diseases.

Occurrence of White Flesh Color and Refreshing Flavor Following Phytoene Synthase 2A Gene Variation in Loquat Fruit. JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2025; 73:10531-10544. [PMID: 40233287 PMCID: PMC12046595 DOI: 10.1021/acs.jafc.4c11968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2024] [Revised: 04/04/2025] [Accepted: 04/09/2025] [Indexed: 04/17/2025]
Abstract
Loquat fruits from the apple tribe of Rosaceae ripen from late spring to early summer, when most fresh fruits are out of season. Compared with the orange-fleshed varieties, the white-fleshed varieties are usually preferentially chosen by consumers for a more favorable flavor. Though the breeding of white-fleshed cultivars with large fruit size greatly promoted the development of loquat production, the mechanisms of how fruits with lighter pigments are generated and how fruit flavor changes following flesh color shifting remain to be elucidated. Pigment measurements indicated carotenoids as the dominant pigment underlying the change in flesh color changing. Genotyping and haplotyping of 807 loquat accessions revealed that the rise of PSY2Ad-PSY2Ad genotype blocks carotenoids accumulation and confers to white flesh color of loquat fruit. Analysis of widely targeted metabolomes on 18 representative cultivars identified 1420 metabolites, with 223 differentially accumulated metabolites between the two groups. Further metabolite comparison demonstrated that low levels of bitter or astringent compounds, such as flavonoids, lignans and coumarins, phenolic acids, nucleotides, alkaloids, and terpenoids, may confer to a refreshing flavor of white-fleshed fruits. Furthermore, 18 metabolic biomarkers were identified by machine learning to distinguish fruits with diverse flesh colors. This work gives insights into the understanding of how fruit color variation associated with flavor and also promotes white-fleshed loquat breeding by genus-wide genotyping.

Abstract
Brain aging is a complex process regulated by genetic, environmental, and metabolic factors, and increasing evidence suggests that environmental pollutants can significantly accelerate this process by interfering with oxidative stress, neuroinflammation, and mitochondrial function-related signaling pathways. Traditional studies have focused on the direct damage of pollutants on macromolecules (e.g., proteins, DNA), while the central role of senescence-associated small molecules (e.g., ROS, PGE2, lactate) in early regulatory mechanisms has been long neglected. In this study, we innovatively proposed a cascade framework of "small molecule metabolic imbalance-signaling pathway dysregulation-macromolecule collapse", which reveals that pollutants exacerbate the dynamics of brain aging through activation of NLRP3 inflammatory vesicles and inhibition of HIF-1α. Meanwhile, to address the technical bottleneck of small molecule spatiotemporal dynamics monitoring, this paper systematically reviews the cutting-edge detection tools such as electrochemical sensors, genetically encoded fluorescent probes and antioxidant quantum dots (AQDs). Among them, AQDs show unique advantages in real-time monitoring of ROS fluctuations and intervention of oxidative damage by virtue of their ultra-high specific surface area, controllable surface modification, and free radical scavenging ability. By integrating multimodal detection techniques and mechanism studies, this work provides a new perspective for analyzing pollutant-induced brain aging and lays a methodological foundation for early intervention strategies based on small molecule metabolic networks.

Abstract
Cellular senescence is intricately linked with numerous changes observed in the aging process, including the depletion of the stem cell pool and the decline in tissue and organ functions. Over the past three decades, efforts to halt and reverse aging have intensified, bringing rejuvenation closer to reality. Current strategies involve treatments using stem cells or their derivatives, such as the secretome. This article aims to highlight key points and evaluate the utilization of secretome derived from mesenchymal stromal cells (MSCs) as an antisenescent approach. Employing a quasi-systematic research approach, the authors conducted a comprehensive analysis based on a search algorithm targeting the in vitro effects of MSC-derived secretome on rescuing cells from a senescent state. Reviewing 39 articles out of 687 hits retrieved from PubMed and Scopus without a time limit, the authors synthesized information and identified common types of MSC-tissue sources utilized (including bone marrow-MSCs, umbilical cord-MSCs, iPSC-derived MSCs, adipose tissue-MSCs, dental pulp-MSCs, amniotic membrane-MSCs, placenta-MSCs, gingival-MSCs, urine-MSCs, and commercially available MSC lineages) from both human and other species (such as mice and rats). The authors also examined the forms of secretome tested (including conditioned media and extracellular vesicles), the cell types treated (MSCs or other cell types), methods/biomarkers of monitoring senescence/rejuvenation, and the mechanisms involved. Ultimately, this review underscores the proof-of-principle of the beneficial effects of MSC-derived secretome in reversing cellular senescence across various cell types. Such insights might aid the scientific community in designing improved in vitro and in vivo assays for future research and clinical validation of this promising cell-free therapy.

Abstract
Currently, there is no specific treatment for diabetes-induced osteoporosis (DOP). Our study identified diabetes-induced cellular senescence, marked by elevated activity of senescence-associated β-galactosidase. Targeting senescent cells holds promise for osteoporosis treatment. We demonstrated that scutellarin (SCU) effectively mitigated bone loss in DOP mice, and co-treatment with SCU significantly reduced diabetes-induced senescence in LepR+MSCs. Furthermore, our research highlighted the role of Nrf2 in SCU's anti-senescence effects on bone. The deletion of Nrf2 impaired SCU's ability to alleviate DOP. Mechanistically, SCU enhances Ezh2 expression and increases H3K27me3 activity at the Keap1 promoter region, leading to Keap1 repression and enhanced Nrf2-ARE signalling. Additionally, SCU notably inhibited cellular senescence and diabetes-related osteoporosis, these effects were significantly reduced in Ezh2LepRcre conditional knockout models. These findings suggest that the Ezh2-Nrf2 signalling axis is crucial for mediating SCU's beneficial effects in this context. Overall, our discoveries provide insights into the mechanisms underlying DOP and propose a potential preventive strategy for this condition.

Abstract
Background: Diabetic cardiomyopathy (DCM), a prevalent complication of diabetes, is a major cause of heart failure and death among patients with diabetes. However, the pathological mechanisms underlying the development of DCM remain unclear. This study aims to investigate the role and underlying mechanisms of caveolin-1 (CAV1) in DCM. Methods: DCM model was established in vivo through intraperitoneal injection of streptozotocin in mice and in vitro through high-glucose (HG) treatment in neonatal rat ventricular myocytes (NRVMs). CAV1-knockout (CAV1-KO) and overexpression (by injecting adeno-associated virus 9 (AAV9) encoding CAV1) mice were utilized to explore the role of CAV1 in DCM. Nuclear factor erythroid 2-related factor 2 (NRF2)-KO and AAV9-NRF2 mice and ML385 (an NRF2 inhibitor) were used to investigate the effect of NRF2 on DCM. Results: CAV1 expression was significantly increased in the cardiac tissues of diabetic mice and HG-treated NRVMs. CAV1 deficiency significantly alleviated diabetes-induced myocardial hypertrophy, fibrosis, abnormal mitochondria, excessive reactive oxygen species production, and ferroptosis. Conversely, cardiac-specific overexpression of CAV1 exacerbated cardiac dysfunction and myocardial histological abnormalities caused by diabetes. Mechanistically, CAV1 directly bound to NRF2 and inhibited its nuclear translocation, reducing the transcription of glutamate cysteine ligase catalytic subunit (GCLC), accumulating excess peroxide, and inducing ferroptosis and myocardial injury. Conclusion: CAV1 exacerbates the progression of DCM by suppressing the NRF2/GCLC pathway, suggesting that targeting CAV1 is a potential therapeutic approach for DCM.

Abstract
Osteoarthritis (OA) is a prevalent joint disease characterized by pain, disability, and loss of physical function, posing a challenge to public health. However, molecular mechanisms of OA pathogenesis have not been fully described. We report that tripartite motif containing 15 (TRIM15) is a regulator in chondrocyte senescence and OA. Our study revealed heightened expression of TRIM15 in chondrocytes of senescent cartilage from patients with OA and in aged wild-type mice. Using gain- and loss-of-function studies, we found that TRIM15 facilitated human chondrocyte senescence. Conditional deletion of Trim15 in mouse chondrocytes severely impaired skeletal growth, partially because of impaired embryonic chondrocyte senescence. Compared with conditionally knocked out Col2a1-CreERT2/Trim15flox/flox mice, Trim15flox/flox control mice exhibited accelerated OA phenotypes, increased senescence markers, and senescence-associated secretory phenotype during aging. Mechanistically, TRIM15 bound with yes-associated protein (YAP) and mediated K48-linked YAP ubiquitination at K254, which interrupted the interaction between YAP and angiomotin, leading to enhanced YAP nuclear translocation. Dysregulation of TRIM15-YAP and transcriptional coactivator with PDZ-binding motif (TAZ) signaling promoted OA progression in both the surgery-induced and natural aging-induced mouse OA model. Intra-articular injection of adeno-associated virus 5 (AAV5)-Trim15 shRNA decelerated OA progression in mice. In particular, YAP and TAZ protein amounts were increased in chondrocytes of patients with OA. Our preclinical results demonstrated that the AAV5-TRIM15 shRNA treatment protected human OA explants against degeneration through inhibiting chondrocyte senescence. Together, our findings underscore the potential of targeting TRIM15 in reshaping the aging cartilage microenvironment and suggest a promising therapeutic avenue for OA.

Int Immunopharmacol 2025; 150:114264. [PMID: 39954658 DOI: 10.1016/j.intimp.2025.114264] [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: 05/18/2024] [Revised: 01/27/2025] [Accepted: 02/06/2025] [Indexed: 02/17/2025]
Abstract
Renal ischemia-reperfusion injury (IRI) makes a significant contribution to delayed graft function (DGF) and reduced allograft survival time post-transplantation, thereby complicating the prognosis of renal transplant recipients. Cordycepin, an active compound purified from the traditional Chinese medicine Cordyceps sinensis, has exhibited remarkable anti-inflammatory and organ-protective effects against various diseases, including neurological, hepatic, and metabolic disorders. Therefore, the present study used a murine model of renal ischemia/reperfusion (I/R) and HK2 cell line hypoxia/reoxygenation (H/R) to determine whether cordycepin influences renal IRI. The findings indicated that cordycepin significantly mitigated renal IRI by inhibiting the p38/JNK signaling pathway in the renal tubular epithelial cells, thereby suppressing inflammation, cell apoptosis, and ferroptosis. These findings offer a novel avenue for improving the prognosis of renal transplant recipients and allograft survival.

Abstract
Radiation-induced skin injury (RSI) presents a significant challenge in wound care due to its complex pathophysiology, which includes increased oxidative stress, impaired angiogenesis, and delayed re-epithelialization. Transcriptomic analysis reveals significant alterations in genes associated with the ferroptosis pathway following radiation exposure. In this study, we introduce microneedles composed of silk fibroin hydrogel loaded with deferoxamine (SF+MNs+DFO) to inhibit ferroptosis. SF+MNs+DFO exhibits optimal mechanical properties and drug release kinetics. Histopathological analysis shows reduced inflammation, oxidative stress, and collagen deposition in RSI treated with SF+MNs+DFO, leading to accelerated tissue regeneration and decreased scarring. Molecular biology studies indicate that SF+MNs+DFO inhibits ferroptosis by reducing the concentration of free Fe2+ in the body, thereby decreasing the generation of reactive oxygen species (ROS) and lipid peroxidation. Immunofluorescence studies further confirm the increased neovascularization and reduced fibrosis in SF+MNs+DFO-treated RSI, indicating enhanced tissue repair. SF+MNs+DFO not only inhibits ferroptosis but also promotes angiogenesis and tissue regeneration, offering a promising therapeutic strategy for RSI. In conclusion, DFO-loaded SF hydrogel microneedles provide precise drug delivery, iron chelation, and improved wound healing, demonstrating an effective approach for treating RSI.

Hepatol Commun 2025; 9:e0633.

Abstract
BACKGROUND Immune checkpoint inhibitors are effective treatments for HCC; however, their therapeutic efficacy is often limited by the development of drug resistance. Therefore, investigating new combination therapeutics involving immune checkpoint inhibitors is critical to improving patient prognosis. In this study, we investigated the therapeutic effect of cordycepin (COR) in HCC and its synergistic effect with anti-programmed cell death ligand 1 (anti-PD-L1) immunotherapy. METHODS We selected 2 HCC cell lines to investigate the effects of COR on HCC growth using in vivo and in vitro experiments. We performed RNA sequencing of the MHCC97H cell line treated with or without COR to understand the underlying mechanism and identify the key regulatory genes. Through in vivo and in vitro experiments on gene knockdown cells, we identified thioredoxin-interacting protein as a key molecule involved in the role of COR. Next, we used mouse subcutaneous and orthotopic tumor models to evaluate the therapeutic effects of COR, atezolizumab (a programmed death-ligand 1 [PD-L1] inhibitor), or their combination. Multiple immunofluorescence staining revealed that the combination of atezolizumab and COR therapy greatly increased the number of tumor-infiltrating CD8+ T cells and PD-L1 expression in HCC compared to monotherapy. RESULTS Our study revealed that COR significantly inhibited HCC growth both in vitro and in vivo. Mechanistically, we showed that COR induces endoplasmic reticulum stress, which upregulates thioredoxin-interacting protein expression and leads to HCC cell pyroptosis. In addition, the combination treatment with COR and PD-L1 inhibitors profoundly inhibited HCC. CONCLUSIONS Overall, our study successfully established a combined therapeutic strategy using COR and PD-L1 inhibitors. This strategy has significant synergistic effects on cancer cells, highlighting its importance in cancer therapy.

Abstract
BACKGROUND The persistent accumulation of senescence cells is one of the characteristics of radiation-induced skin injury (RISI), leading to fibrosis and impaired healing. However, the reasons why these senescence cells are resistant to clearance remain unclear. METHODS The mouse RISI model was established using an X-ray generator, and a shield was used to cover all areas except the skin of the right leg or back for protecting surrounding tissue. ScRNA sequencing, immunohistochemistry, immunofluorescence, qPCR, western blot, primary cell co-culture system and fluorescence microsphere phagocytosis assay were performed for the functional and mechanistic investigations. RESULTS The dynamic changes of senescence cell levels and multiple immune cell levels during RISI were evaluated, we found that macrophages could remove senescence cells from the dermis, and the clearance ability gradually strengthens over time. ScRNA sequencing revealed that macrophages with high senescence clearance capacity exhibited increased NOD-like receptor family pyrin domain-containing 3 (NLRP3) expression compared to those with low senescence clearance capacity. Inhibition or conditional knockout of Nlrp3 in macrophages led to senescence cell clearance dysfunction and impaired healing. Further studies found that interleukin-33 secreted by senescence cells inhibited the expression of NLRP3 in macrophages and their ability to phagocytize senescence cells, especially in the early stages after radiation. In addition, Nocardia rubra cell wall skeleton (Nr-CWS), an approved immunomodulator, was found to activate macrophage NLRP3 expression, reduce senescence cell burden, and accelerate the healing of RISI. CONCLUSION This study underscored NLRP3 in macrophages as a critical intervention target for senescence cell immunosurveillance and emphasized Nr-CWS as a potential therapeutic agent for accelerating senescence cell clearance in RISI.

Cordycepin ameliorates spaceflight-induced osteoporosis by preventing BMSCs oxidative stress and senescence via interacting with PI3K p110α and regulating PI3K/Akt/FOXO3 signalling. Free Radic Biol Med 2025; 228:108-125.

Abstract
Spaceflight-induced osteoporosis (SFOP) is a detrimental healthcare consequence during spaceflight. Weightlessness and ionizing radiation were main environmental factors that contribute to SFOP, especially in the manned deep space voyages. However, currently there is scarce effective method to treat SFOP. This study aims at discovering the role and mechanism of cordycepin (COR) in treating SFOP. A combined ionizing radiation and tail suspension (IR/IS) model is constructed in mice to simulate SFOP. COR injection exhibits certain dose-dependent therapeutic effects including better imageological bone index and improved histological bone regeneration in treating SFOP, which is most prominent at a dose of 20 mg/kg. A combined radiation and microgravity (R/M) model is established to treat BMSCs in vitro. 10 μM COR alleviates oxidative stress and cellular senescence of BMSCs. Through high-throughput sequencing, molecular docking and microscale thermophoresis (MST), we reveal a novel mechanism that COR interacts with p110α subunit in PI3K isoform α (PI3Kα) and inhibits PI3K kinase activity, which then regulates the PI3K/Akt/FOXO3 signalling. To elevate the bioavailability of COR in the SFOP treatment, a BMSCs-targeted delivery system that uses exosomes (Exos) modified with BMSC-affinity peptide E7 (E7-Exos) is constructed and loaded with COR. E7-Exos loaded COR reduces the dosage of COR to 5 mg/kg while enhancing the therapeutic effect than using 20 mg/kg COR alone in treating SFOP. In conclusion, COR shows promise as a potential agent in SFOP therapy.

Abstract
Non-alcoholic fatty liver disease (NAFLD) has emerged as a global health concern, placing a substantial financial strain on public health systems. Currently, no specific pharmacological treatments are recommended in existing guidelines. Abscisic acid (ABA), a natural plant hormone, is recognized for its promising potential in the healthcare field due to its diverse biological activities. Therefore, this study is aimed at exploring the protective mechanism of ABA against NAFLD. In vitro, experiments were conducted using palmitic acid (PA) to establish a fatty liver cell model, whereas in vivo, an NAFLD model was established using a continuous high-fat diet (HFD). It was found that ABA, as a natural activator of NRF2 and AMPK, reduced lipid accumulation in hepatocytes and exerted anti-inflammatory and antioxidant effects by enhancing the nuclear expression of NRF2, thereby alleviating NAFLD in mice. Furthermore, AMPK was activated by ABA through the promotion of its phosphorylation, which subsequently enhanced the p62-dependent autophagic degradation of KEAP1, leading to the release and nuclear translocation of NRF2. In conclusion, it is indicated that ABA reduces lipid accumulation, inflammation, and oxidative stress in hepatocytes via the NRF2 and AMPK pathways, potentially serving as a promising candidate for alleviating NAFLD.

Abstract
Esophageal cancer is an aggressive malignancy with a poor prognosis. NUC7738, a cordycepin derivative, has shown promise in overcoming the limited in vivo efficacy of its parent compound. This study compares the anticancer effects of NUC7738 and cordycepin in esophageal cancer and explores the molecular mechanisms of NUC7738 action. In vitro, NUC7738 and cordycepin were tested on normal (Het1A) and esophageal cancer cell lines (ECA109, KYSE510) using Cell Counting Kit-8 (CCK-8) and colony formation assays. Apoptosis was confirmed by inhibitors and flow cytometry. Western blot was performed to detect apoptosis-related protein. KEGG analysis identified potential downstream signaling pathways, while qPCR, western blot, and immunofluorescence staining were applied to assess p53 expression and stability. In vivo, ECA109 cells were xenografted into nude mice, and tumor tissues were analyzed for p53 expression using Immunohistochemical staining. Finally, CCK-8, colony formation, and subcutaneous tumor xenograft assays in nude mice were employed to assess the synergistic effects of NUC7738 and cisplatin. The results revealed that NUC7738, although less effective than cordycepin in vitro, demonstrated superior anticancer activity in vivo. NUC7738 induced apoptosis by stabilizing p53 via ubiquitination, inhibiting tumor growth. Additionally, NUC7738 combined with cisplatin showed enhanced anticancer effects both in vitro and in vivo. These findings highlight greater potential of NUC7738 for clinical application, particularly in improving p53 stability and augmenting chemotherapeutic efficacy.

FEBS Open Bio 2025; 15:335-345.

Abstract
Obesity, a global health concern, results from an energy imbalance leading to lipid accumulation. In the present study, Cordyceps militaris extract (CM) and its primary component, cordycepin, were investigated to characterize their potential effects on adipogenesis and lipolysis. Treatment with CM or cordycepin reduced lipid droplets and increased hormone-sensitive lipase activation in 3T3-L1 cells. In a diabetic obese mouse model, CM and cordycepin lowered serum low-density lipoprotein/very low-density lipoprotein levels and reduced oxidative stress and cell senescence markers. Thus, cordycepin inhibits preadipocyte differentiation and promotes lipolysis, which may serve as a novel obesity treatment. Further studies, including clinical trials, are required to validate the clinical potential of cordycepin.

Abstract
Radiotherapy (RT) is widely applied in tumor therapy, but inevitable side effects, especially for skin radiation injury, are still a fatal problem and life-threatening challenge for tumor patients. The main components of topical radiation protection preparations currently available on the market are antioxidants, such as SOD, which are limited by their unstable activity and short duration of action, making it difficult to achieve the effects of radiation protection and skin radiation damage treatment. Therefore, we designed a drug-free antioxidant hydrogel patch with encapsulated bioactive epidermal growth factor (EGF) for the treatment of radiation skin injury. The X-ray responsive hydrogel formed by copolymerization of the disulfide-containing hyperbranched poly(β-hydrazide ester) macromer polymer (PBAE), methacryloylated hyaluronic acid, and acrylamide exhibits continuous antioxidant activity through the oxidation of disulfide bonds in PBAE as well as the triggered release of EGF after X-ray responsive breakage of the polymer network to finally promote radioactive wound healing. Upon radiotherapy, the antioxidant hydrogel is able to alleviate local oxidative stress by continuously eliminating excessive ROS and can prevent deterioration of radiation skin injury. Moreover, the drug-free hydrogel with its excellent antioxidant property can overcome the disadvantages of traditional medicine (such as poor solubility, random diffusion, rapid drug clearance, and interference with tumor efficacy). Notably, the drug-free hydrogel exhibits a negligible effect for tumor therapy because the antioxidant hydrogel acts only on the epidermis and displays no shielding effect for ionization radiation. Ultimately, in vivo animal studies affirm the efficacy of our methodology, wherein the administration of the antioxidant hydrogel on acute irradiated skin attenuates the progression of radiation skin injury and promotes radioactive wound healing. This innovative strategy points out a new inspiration for the precise treatment of skin radiation damage with X-ray responsive antioxidant drug-free hydrogels.

Abstract
Radiation-induced skin injury (RISI) is a prevalent complication following nuclear accidents and radiotherapy for tumors. The associated side effects may include erythema, desquamation, ulceration, and in severe cases, necrosis of certain skin tissues. These adverse reactions significantly impact the quality of life for patients and contribute to both psychological distress and economic burdens. However, there is currently no standardized protocol for the treatment and management of RISI. In comparison to traditional pharmaceuticals, the utilization of biomaterials in addressing radiation-induced diseases has garnered increasing attention due to their superior biocompatibility and outstanding functionality. Nevertheless, comprehensive reviews on this topic remain scarce. In this context, this paper systematically elucidates the pathogenesis of RISI, subsequently introducing the clinical manifestations and advancements in treatment for RISI. It emphasizes a comprehensive discussion on the design and innovation of novel biomaterials aimed at treating and protecting against RISI, while also illustrating the mechanisms by which multifunctional biomaterials enhance both treatment efficacy and protective measures for radiation-induced skin conditions. Finally, it addresses the challenges encountered by multifunctional biomaterials in managing radiation-related diseases and outlines potential directions for future research efforts. The objective of this review is to investigate the therapeutic and protective effects of multifunctional biomaterials in relation to radiation-induced skin injury, thereby providing significant reference value for the design and clinical application of innovative materials.

Abstract
Regenerating periodontal bone defect surrounding periodontal tissue is crucial for orthodontic or dental implant treatment. The declined osteogenic ability of periodontal ligament stem cells (PDLSCs) induced by inflammation stimulus contributes to reduced capacity to regenerate periodontal bone, which brings about a huge challenge for treating periodontitis. Here, inspired by the adhesive property of mussels, we have created adhesive and mineralized hydrogel microspheres loaded with traditional compound cordycepin (MMS-CY). MMS-CY could adhere to the surface of alveolar bone, then promote the migration capacity of PDLSCs and thus recruit them to inflammatory periodontal tissues. Furthermore, MMS-CY rescued the impaired osteogenesis and ligament-forming capacity of PDLSCs, which were suppressed by the inflammation stimulus. Moreover, MMS-CY also displayed the excellent inhibitory effect on the osteoclastic activity. Mechanistically, MMS-CY inhibited the premature senescence induced by the inflammation stimulus through the nuclear factor erythroid 2-related factor (NRF2) pathway and reducing the DNA injury. Utilizing in vivo rat periodontitis model, MMS-CY was demonstrated to enhance the periodontal bone regeneration by improving osteogenesis and inhibiting the osteoclastic activity. Altogether, our study indicated that the multi-pronged approach is promising to promote the periodontal bone regeneration in periodontitis condition by reducing the inflammation-induced stem cell senescence and maintaining bone homeostasis.

Abstract
BACKGROUND Streptococcus mutans (S. mutans) contributes to caries. The biofilm formed by S. mutans exhibits greater resistance to drugs and host immune defenses than the planktonic form of the bacteria. The objective of this study was to evaluate the anti-biofilm effect of cordycepin from the perspective of metabolomics. METHODS The minimum inhibitory concentration (MIC) was determined to evaluate the antimicrobial effect of cordycepin on planktonic S. mutans. The 24-h biofilm was treated with 128 µg/mL of cordycepin for 10 min at the 8- or 20-h time points. Biofilm biomass and metabolism were assessed using crystal violet and MTT assays and cordycepin cytotoxicity was evaluated in human oral keratinocytes (HOK) using CCK-8 assays. The live bacterial rate and the biofilm volume were assessed by confocal laser scanning microscopy. Metabolic changes in the biofilm collected at different times during with cordycepin were analyzed by metabolomics and verified by quantitative real-time PCR. RESULTS The results showed that treatment with 128 µg/mL cordycepin reduced both the biomass and metabolic activity of the biofilm without killing the bacteria, and cordycepin at this concentration showed good biocompatibility. Metabolomics analysis showed that differentially abundant metabolites following cordycepin treatment were mainly related to purine and nucleotide metabolism. After immediate treatment with cordycepin, genes related to purine and nucleotide metabolism were downregulated, and the levels of various metabolites changed significantly. However, the effect was reversible. After continuing culture for 4 h, the changes in genes and most metabolites were reversed, although the levels of 2'-deoxyadenosine, 2'-deoxyinosine, and adenine remained significantly different. CONCLUSIONS Cordycepin has the effect of anti-biofilm of S. mutans, mainly related to purine and nucleotide metabolism.

Abstract
Aging impairs bone marrow mesenchymal stem cell (BMSC) functions as well as associated angiogenesis which is critical for bone regeneration and repair. Hence, repairing bone defects in elderly patients poses a formidable challenge in regenerative medicine. Here, the engineered dental pulp stem cell-derived exosomes loaded with the natural derivative of adenosine Cordycepin (CY@D-exos) are fabricated by means of the intermittent ultrasonic shock, which dually rejuvenates both senescent BMSCs and endothelial cells and significantly improve bone regeneration and repair in aged animals. CY@D-exos can efficiently overcome the senescence of aged BMSCs and enhance their osteogenic differentiation by activating NRF2 signaling and maintaining heterochromatin stability. Importantly, CY@D-exos also potently overcomes the senescence of vascular endothelial cells and promotes angiogenesis. In vivo injectable gelatin methacryloyl (GelMA) hydrogels with sustained release of CY@D-exos can accelerate bone injury repair and promote new blood vessel formation in aged animals. Taken together, these results thus demonstrate that cordycepin-loaded dental pulp stem cell-derived exosomes display considerable potential to be developed as a next-generation therapeutic agent for promoting aged bone regeneration and repair.

Abstract
Cellular senescence is an adverse factor in the development of pulmonary fibrosis (PF). Ginsenoside Rb1 has been found to inhibit both cellular senescence and PF. This study aimed to elucidate the molecular mechanisms by which ginsenoside Rb1 regulates cellular senescence and PF. A PF mouse model was established by Bleomycin (BLM) administration, and a cell model of senescence was constructed using MRC-5 cells treated with Adriamycin RD (ARD) administration. Hematoxylin and Eosin (HE) staining and Masson staining were employed to evaluate cellular structure and collagen fiber content. RT-qPCR and western blotting were used to detect mRNA and protein expression of the target genes. Enzyme-linked Immunosorbent Assay (ELISA) was applied to measure the protein concentration of IL-1[Formula: see text] and IL-18. SA-[Formula: see text]-gal staining was used to evaluate cellular senescence. Our results show that ginsenoside Rb1 effectively suppressed BLM-induced PF in mice. ARD administration to induce cellular senescence reduced NRF2, QKI, and SMAD7 expression in MRC-5 cells. By inducing NRF2 overexpression, ARD-induced cellular senescence and fibrosis in MRC-5 cells were relieved. Notably, NRF2 knockdown abolished the mitigating effects of ginsenoside Rb1 on ARD-induced cellular senescence and fibrosis in MRC-5 cells. Mechanistically, NRF2 increased SMAD7 mRNA stability through the transcriptional regulation of QKI. As expected, ginsenoside Rb1 alleviated ARD-induced senescence and fibrosis in MRC-5 cells by activating the NRF2/QKI/SMAD7 axis. Therefore, it was found that ginsenoside Rb1 mitigates cellular senescence and fibrosis during PF progression by activating the NRF2/QKI/SMAD7 axis. This study provides a potential therapeutic strategy for the treatment of PF and elucidates its mechanism of action.

Abstract
Chronic kidney disease (CKD) is characterized by irreversible progressive worsening of kidney function leading to kidney failure. CKD is viewed as a clinical model of premature aging and to date, there is no treatment to reverse kidney damage. The well-established treatment for CKD aims to control factors that may aggravate kidney progression and to provide kidney protection effects to delay the progression of kidney disease. As an alternative, Traditional Chinese Medicine (TCM) has been shown to have fewer adverse effects for CKD patients. However, there is a lack of clinical and molecular studies investigating the mechanisms by which natural products used in TCM can improve CKD. In recent years, autophagy and cellular senescence have been identified as key contributors to aging and age-related diseases. Exploring the potential of natural products in TCM to target these processes in CKD patients could slow disease progression. A better understanding of the characteristics of these natural products and their effects on autophagy and cellular senescence through clinical studies, coupled with the use of these products as complementary therapy alongside mainstream treatment, may maximize therapeutic benefits and minimize adverse effects for CKD patients. While promising, there is currently a lack of thorough research on the potential synergistic effects of these natural products. This review examines the use of natural products in TCM as an alternative treatment for CKD and discusses their active ingredients in terms of renoprotection, autophagy, and cellular senescence.

Abstract
BACKGROUND PD-L1 blockade has been found to be effective in treating multiple malignancies. Combined therapy is proposed to provide better therapeutic effects. Cordycepin, a prominent bioactive compound found in cordyceps, can inhibit the development of various cancers. PURPOSE This study aimed to determine the efficacy of combined anti-PD-L1 antibody and cordycepin in tumor treatment. METHODS A single-cell RNA sequencing was used to analyze the mechanism of combined treatment. RESULTS Combination therapy of anti-PD-L1 and cordycepin significantly inhibited tumor growth by regulating the T cell ratio and improving the function of CD8+T cells. Furthermore, cordycepin promoted the reprogramming of type-II macrophages into type-I macrophages, a process confirmed through flow cytometry analysis of the underlying mechanism. CONCLUSION Our findings demonstrate that the combination of anti-PD-L1 and cordycepin effectively suppressed tumor growth by regulating the proportion of T cells and reprograming type-II macrophages.

Abstract
Purpose Skin radiation damage is a prevalent form of tissue injury encountered during radiotherapy, radiation accidents, and occupational exposure. The only clinically approved radioprotective agent, amifostine, is associated with numerous side effects, underscoring the urgent need for the development of safe and effective radioprotective agents. Natural products with reductive properties possess high antioxidant activity and biocompatibility, but their low bioavailability limits their radioprotective efficacy and clinical application. To address this, we utilized epigallocatechin gallate (EGCG) as a model compound and employed nanotechnology to enhance cellular uptake of natural compounds, thereby improving their free radical scavenging capabilities. Methods EGCG nanoparticles (EGCG NPs) with robust intracellular reactive oxygen species (ROS) scavenging ability were prepared via self-assembly. The morphology, size distribution, and antioxidant capacity of EGCG NPs were characterized. Cytocompatibility, intracellular ROS levels and DNA damage, cell migration and immune response of EGCG NPs to macrophages were tested in vitro. The in vivo radiation protection and biocompatibility of EGCG NPs were assessed in murine model. Results The EGCG NPs was successfully prepared and compared to free EGCG, EGCG NPs demonstrated better cellular uptake, significantly enhancing their biocompatibility, intracellular ROS scavenging capacity, and ability to mitigate DNA damage. Furthermore, EGCG NPs facilitated fibroblast proliferation and migration, while inhibiting the polarization of macrophages towards the M1 phenotype in vitro. In animal levels, EGCG NPs exhibited markedly improved radioprotective efficacy over free EGCG, effectively reducing skin edema and ulceration, alleviating pathological conditions such as interstitial edema, dermal fluid accumulation, and inflammatory infiltration, decreasing the duration of skin injury, and promoting wound healing. Conclusion This work offers novel insights into the therapeutic application of EGCG NPs as a potential alternative for skin radioprotection and provides a powerful approach for developing radioprotective agents derived from natural products.

Abstract
BACKGROUND Radiation-induced myelopathy (RM) is a significant complication of radiotherapy with its mechanisms still not fully understood and lacking effective treatments. Compound 7 (C7) is a newly identified, potent, and selective inhibitor of the Keap1-Nrf2 interaction. This study aimed to explore the protective effects and mechanisms of C7 on RM in vitro and in vivo. METHODS Western blotting, quantitative real-time polymerase chain reaction (qRT-PCR), reactive oxygen species (ROS) and mitochondrial polarization, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, genetic editing techniques, locomotor functions, and tissue staining were employed to explore the protective effects and underlying mechanisms of C7 in radiation-induced primary rat microglia and BV2 cells, as well as RM rat models. RESULTS In this study, we found that C7 inhibited the production of pro-inflammation cytokines and oxidative stress induced by irradiation in vitro. Further, the data revealed that radiation worsened the locomotor functions in rats, and C7 significantly improved histological and functional recovery in RM rats. Mechanically, C7 activated Nrf2 signaling and promoted the microglia transformation from M1 to M2 phenotype. CONCLUSION C7 could ameliorate RM by boosting Nrf2 signaling and promoting M2 phenotype microglia polarization in vitro and in vivo.

Abstract
Ionizing radiation (IR)-induced intestinal injury remains a major limiting factor in abdominal radiation therapy, and its pathogenesis remains unclear. In this study, mouse models of IR-induced intestinal injury were established, and the effect of IR on nuclear factor erythroid 2-related factor 2 (Nrf2) was determined. More severe IR-induced intestinal damage was observed in Nrf2 knockout (KO) mice than in wild-type mice. Then, the negative regulation of cyclic GMP-AMP synthase/stimulator of interferon genes (cGAS/STING) signaling by Nrf2 was examined both in vivo and in vitro after IR. This was accompanied by alterations in the intestinal neutrophil and macrophage populations in mice. Subsequently, the effect of the cGAS/STING pathway on the intestinal toxicity of IR was also investigated. Moreover, the downregulation of cGAS/STING by Nrf2 via its target gene, Pirin, was confirmed using transfection assays. A rescue experiment with Pirin was also conducted using adeno-associated virus in Nrf2 KO mice. Finally, the protective effect of calcitriol against IR-induced intestinal injury, along with increased Nrf2 and Pirin levels and decreased cGAS, pSTING, and interferon-beta levels, were observed. Taken together, our results suggest that Nrf2 alleviates IR-induced intestinal injury through Pirin-mediated inhibition of the innate immunity-related cGAS/STING pathway.

Abstract
Radiation-induced intestinal injury is one of the most common intestinal complications caused by pelvic and abdominal tumor radiotherapy, severely impacting patients' quality of life. Ionizing radiation, while killing tumor cells, inevitably damages healthy tissue. Radiation-induced enteropathy results from radiation therapy-induced intestinal tissue damage and inflammatory responses. This damage involves various complex molecular mechanisms, including cell apoptosis, oxidative stress, release of inflammatory mediators, disruption of immune responses, and imbalance of intestinal microbiota. A thorough understanding of these molecular mechanisms is crucial for developing effective prevention and treatment strategies.

Abstract
Cutaneous wound healing is a complex multi-step process that is highly controlled, ensuring efficient repair to damaged tissue and restoring tissue architecture. Multiple cell types play a critical role in wound healing, and perturbations in this can lead to non-healing wounds or scarring and fibrosis. Thus, the process is tightly regulated and controlled. Cellular senescence is defined as irreversible cell cycle arrest and is associated with various phenotypic changes and metabolic alterations and coupled to a secretory program. Its role in wound healing, at least in the acute setting, appears to help promote appropriate mechanisms leading to the complete restoration of tissue architecture. Opposing this is the role of senescence in chronic wounds where it can lead to either chronic non-healing wounds or fibrosis. Given the two opposing outcomes of wound healing in either acute or chronic settings, this has led to disparate views on the role of senescence in wound healing. This review aims to consolidate knowledge on the role of senescence and aging in wound healing, examining the nuances of the roles in the acute or chronic settings, and attempts to evaluate the modulation of this to promote efficient wound healing.

Abstract
The human skin, the body's largest organ, undergoes continuous renewal but is significantly impacted by aging, which impairs its function and leads to visible changes. This study aimed to identify botanical compounds that mimic the anti-aging effects of baricitinib, a known JAK1/2 inhibitor. Through in silico screening of a botanical compound library, 14 potential candidates were identified, and 7 were further analyzed for their effects on cellular aging. The compounds were tested on both normal aged fibroblasts and premature aging fibroblasts derived from patients with Hutchinson-Gilford Progeria Syndrome (HGPS). Results showed that these botanical compounds effectively inhibited the JAK/STAT pathway, reduced the levels of phosphorylated STAT1 and STAT3, and ameliorated phenotypic changes associated with cellular aging. Treatments improved cell proliferation, reduced senescence markers, and enhanced autophagy without inducing cytotoxicity. Compounds, such as Resveratrol, Bisdemethoxycurcumin, Pinosylvin, Methyl P-Hydroxycinnamate, cis-Pterostilbene, and (+)-Gallocatechin, demonstrated significant improvements in both control and HGPS fibroblasts. These findings suggest that these botanical compounds have the potential to mitigate age-related cellular alterations, offering promising strategies for anti-aging therapies, particularly for skin health. Further in vivo studies are warranted to validate these results and explore their therapeutic applications.

Abstract
Carbon dots (CDs), a type of nanoparticle with excellent optical properties, good biocompatibility, and small size, are finding increasing application across the fields of biology and biomedicine. In recent years, biomass-derived CDs with pharmacological activity (BP-CDs) derived from herbal medicines (HMs), HMs extracts and other natural products with demonstrated pharmaceutical activity have attracted particular attention. Herein, we review recent advances in the development of BP-CDs, covering the selection of biomass precursors, different methods used for the synthesis of BP-CDs from natural sources, and the purification of BP-CDs. Additionally, we summarize the many remarkable properties of BP-CDs including optical properties, biocompatibility and pharmaceutical efficacy. Moreover, the antibacterial, antiviral, anticancer, biosensing, bioimaging, and other applications of BP-CDs are reviewed. Thereafter, we discuss the advantages and disadvantages of BP-CDs and Western drug-derived CDs, highlighting the excellent performance of BP-CDs. Finally, based on the current state of research on BP-CDs, we suggest several aspects of BP-CDs that urgently need to be addressed and identify directions that should be pursued in the future. This comprehensive review on BP-CDs is expected to guide the precise design, preparation, and future development of BP-CDs, thereby advancing the application of BP-CDs in biomedicine.

Abstract
Rescuing or compensating mitochondrial function represents a promising therapeutic avenue for radiation-induced chronic wounds. Adult stem cell efficacies are primarily dependent on the paracrine secretion of mitochondria-containing extracellular vesicles (EVs). However, effective therapeutic strategies addressing the quantity of mitochondria and mitochondria-delivery system are lacking. Thus, in this study, we aimed to design an effective hydrogel microneedle patch (MNP) loaded with stem cell-derived mitochondria-rich EVs to gradually release and deliver mitochondria into the wound tissues and boost wound healing. We, first, used metformin to enhance mitochondrial biogenesis and thereby increasing the secretion of mitochondria-containing EVs (termed "Met-EVs") in adipose-derived stem cells. To verify the therapeutic effects of Met-EVs, we established an in vitro and an in vivo model of X-ray-induced mitochondrial dysfunction. The Met-EVs ameliorated the mitochondrial dysfunction by rescuing mitochondrial membrane potential, increasing adenosine 5'-triphosphate levels, and decreasing reactive oxygen species production by transferring active mitochondria. To sustain the release of EVs into damaged tissues, we constructed a Met-EVs@Decellularized Adipose Matrix (DAM)/Hyaluronic Acid Methacrylic Acid (HAMA)-MNP. Met-EVs@DAM/HAMA-MNP can load and gradually release Met-EVs and their contained mitochondria into wound tissues to alleviate mitochondrial dysfunction. Moreover, we found Met-EVs@DAM/HAMA-MNP can markedly promote macrophage polarization toward the M2 subtype with anti-inflammatory and regenerative functions, which can, in turn, enhance the healing process in mice with skin wounds combined radiation injuries. Collectively, we successfully fabricated a delivery system for EVs, Met-EVs@DAM/HAMA-MNP, to effectively deliver stem cell-derived mitochondria-rich EVs. The effectiveness of this system has been demonstrated, holding great potential for chronic wound treatments in clinic.

Exercise activates AMPK in mouse and human pancreatic islets to decrease senescence. Nat Metab 2024; 6:1976-1990.

Abstract
Beta (β)-cell senescence contributes to type 2 diabetes mellitus (T2DM). While exercise is vital for T2DM management and significantly affects cellular ageing markers, its effect on β-cell senescence remains unexplored. Here, we show that short-term endurance exercise training (treadmill running, 1 h per day for 10 days) in two male and female mouse models of insulin resistance decreases β-cell senescence. In vivo and in vitro experiments revealed that this effect is mediated, at least in part, by training-induced increases in serum glucagon, leading to activation of 5'-AMP-activated protein kinase (AMPK) signalling in β-cells. AMPK activation resulted in the nuclear translocation of NRF2 and decreased expression of senescence markers and effectors. Remarkably, human islets from male and female donors with T2DM treated with serum collected after a 10-week endurance exercise training programme showed a significant decrease in the levels of senescence markers. These findings indicate that exercise training decreases senescence in pancreatic islets, offering promising therapeutic implications for T2DM.

[PMID: 39326562 DOI: 10.1016/j.arthro.2024.09.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 08/31/2024] [Accepted: 09/05/2024] [Indexed: 09/28/2024]
Abstract
PURPOSE To explore the potential of M2 macrophage-derived exosomes (M2-Exos) in enhancing tendon-to-bone healing in aged rats by mitigating cellular senescence of bone marrow-derived stem cells (BMSCs). METHODS In vitro, the effects of M2-Exos on alleviating cellular senescence and improving chondrogenic potential of senescent BMSCs were evaluated. Rats (24 young and 48 aged) with chronic rotator cuff tear (RCT) were repaired and assigned into 3 groups: young group (young rats injected with fibrin at the enthesis), aged group (aged rats injected with fibrin at the enthesis), and aged + M2-Exos group (aged rats injected with fibrin containing M2-Exos at the enthesis). At 6 and 12 weeks after repair, enthesis regeneration was evaluated. Proteomic analysis was conducted to explore the mechanism through which M2-Exos mitigated cellular senescence. RESULTS In senescent BMSCs treated with M2-Exos, there was a reduction in senescence biomarkers including senescence-associated β-galactosidase, p53, p21, and senescence-associated secretory phenotype (P < .001). M2-Exos also enhanced chondrogenic potential of senescent BMSCs, reflected in greater Bern score (P < .001) and increased expression of Sox9 (P = .013), Col2a1 (P < .001), and Acan (P < .001). Histologically, aged rats treated with M2-Exos demonstrated significantly greater histologic scores (P < .001 at both 6 and 12 weeks) and increased fibrocartilage regeneration at the enthesis. Biomechanically, these rats exhibited greater failure load, stiffness, and stress (all P < .001) at 12 weeks. Mechanistically, proteomic analysis suggested that M2-Exos might alleviate cellular senescence by potentially regulating DNA replication and repair. CONCLUSIONS M2-Exos can significantly alleviate BMSC senescence and thereby enhance tendon-to-bone healing in an aged rat RCT model. CLINICAL RELEVANCE This study suggests the potential utility of M2-Exos as a therapy for RCT in the older population.

Abstract
Radiation therapy for cancer treatment brings about a series of radiation injuries to normal tissues. In recent years, the discovery of copper-regulated cell death, cuproptosis, a novel form of programmed cell death, has attracted widespread attention and exploration in various biological functions and pathological mechanisms of copper metabolism and cuproptosis. Understanding its role in the process of radiation injury may open up new avenues and directions for exploration in radiation biology and radiation oncology, thereby improving tumor response and mitigating adverse reactions to radiotherapy. This review provides an overview of copper metabolism, the characteristics of cuproptosis, and their potential regulatory mechanisms in radiation injury.

Abstract
Background Radiation therapy has become an important treatment for many malignant tumours after surgery and for palliative tumour care. Although modern radiotherapy technology is constantly improving, radiation damage to normal tissues is often difficult to avoid, and radiation-induced skin injury (RSI) is a common complication, manifested as skin erythema, peeling, ulceration, and even bone and deep organ damage, seriously affect the quality of life for patients. Basic research and clinical trials related to RSI have achieved certain results, while no researchers have conducted comprehensive bibliometric studies. Objective A comprehensive bibliometric analysis of publications on RSI published between 2004 and 2023 was conducted to identify current hotspots and future directions in this area of study. Methods RSI-related publications published between January 1, 2004, and December 31, 2023, were retrieved from the Web of Science Core Collection (WoSCC) database for analysis using VOSviewer and CiteSpace analytics. Results A total of 1009 publications on RSI from 2004 to 2023 were included in the WoSCC database. The United States had the highest productivity with 299 papers, accounting for 29.63% of the total production, followed by China with 193 papers (19.13%) and Japan with 111 papers (11.00%). In terms of research institutions and journals, the University of Toronto and Journal of Supportive Care in Cancer published the highest number of papers. Professor Edward Chow published the most articles, while Professor Shuyu Zhang was the most cited. The top ten most-cited papers focused on the pathogenesis, prevention, and management of RSI. Keyword co-occurrence analysis and the top 25 keywords with the strongest citation bursts suggest that current research focuses on the pathogenesis, prevention, and treatment management of RSI. Conclusion This study conducted a systematic bibliometric analysis of RSI publications from 2004 to 2023; identified the trends in RSI publications, major research countries, major research institutions, major research journals, major research authors, and major research keywords; and revealed the future development direction and research hotspots of this field. This study provides a valuable reference for future RSI research.

Abstract
Neoadjuvant radiotherapy, a preoperative intervention regimen for reducing the stage of primary tumors and surgical margins, has gained increasing attention in the past decade. However, radiation-induced skin damage during neoadjuvant radiotherapy exacerbates surgical injury, remarkably increasing the risk of refractory wounds and compromising the therapeutic effects. Radiation impedes wound healing by increasing the production of reactive oxygen species and inducing cell apoptosis and senescence. Here, a self-assembling peptide (R-peptide) and hyaluronic-acid (HA)-based and cordycepin-loaded superstructure hydrogel is prepared for surgical incision healing after neoadjuvant radiotherapy. Results show that i) R-peptide coassembles with HA to form biomimetic fiber bundle microstructure, in which R-peptide drives the assembly of single fiber through π-π stacking and other forces and HA, as a single fiber adhesive, facilitates bunching through electrostatic interactions. ii) The biomimetic superstructure contributes to the adhesion and proliferation of cells in the surgical wound. iii) Aldehyde-modified HA provides dynamic covalent binding sites for cordycepin to achieve responsive release, inhibiting radiation-induced cellular senescence. iv) Arginine in the peptides provides antioxidant capacity and a substrate for the endogenous production of nitric oxide to promote wound healing and angiogenesis of surgical wounds after neoadjuvant radiotherapy.

Abstract
Radiation causes damage to normal tissues that leads to increased oxidative stress, inflammation, and fibrosis, highlighting the need for the selective radioprotection of healthy tissues without hindering radiotherapy effectiveness in cancer. This study shows that adiponectin, an adipokine secreted by adipocytes, protects normal tissues from radiation damage invitro and invivo. Specifically, adiponectin (APN) reduces chronic oxidative stress and fibrosis in irradiated mice. Importantly, APN also conferred no protection from radiation to prostate cancer cells. Adipose tissue is the primary source of circulating endogenous adiponectin. However, this study shows that adipose tissue is sensitive to radiation exposure exhibiting morphological changes and persistent oxidative damage. In addition, radiation results in a significant and chronic reduction in blood APN levels from adipose tissue in mice and human prostate cancer patients exposed to pelvic irradiation. APN levels negatively correlated with bowel toxicity and overall toxicities associated with radiotherapy in prostate cancer patients. Thus, protecting, or modulating APN signaling may improve outcomes for prostate cancer patients undergoing radiotherapy.

Abstract
Radiation-induced heart disease (RIHD), characterized by severe oxidative stress and immune dysregulation, is a serious condition affecting cancer patients undergoing thoracic radiation. Unfortunately, clinical interventions for RIHD are lacking. Selenium (Se) is a trace element with excellent antioxidant and immune-modulatory properties. However, its application in heart radioprotection remains challenging. Herein, we developed a novel bioactive Cordyceps militaris-based Se oral delivery system (Se@CM), which demonstrated superior radioprotection effects in vitro against X-ray-induced damage in H9C2 cells through suppressing excessive ROS generation, compared to the radioprotectant Amifostine. Moreover, Se@CM exhibited exceptional cardioprotective effects in vivo against X-ray irradiation, reducing cardiac dysfunction and myocardial fibrosis by balancing the redox equilibrium and modulating the expression of Mn-SOD and MDA. Additionally, Se@CM maintained immuno-homeostasis, as evidenced by the upregulated population of T cells and M2 macrophages through modulation of selenoprotein expression after irradiation. Together, these results highlight the remarkable antioxidant and immunity modulation properties of Se@CM and shed light on its promising application for cardiac protection against IR-induced disease. This research provides valuable insights into developing effective strategies for preventing and managing RIHD.

Abstract
Oresitrophe is monotypic, with the only species, Oresitrophe rupifraga Bunge, which is exclusive to China, having special growth and developmental traits due to its habitat. Furthermore, it has bright flowers and medicinal benefits. This study investigated the metabolites present in various tissues of Oresitrophe rupifraga Bunge. Using a widely targeted metabolomics approach, 1965 different metabolites were identified in Oresitrophe rupifraga Bunge. Based on principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA), the aboveground and underground metabolites of Oresitrophe rupifraga differed significantly. The comparison between bulblets and leaves revealed the differential expression of 461 metabolites, whereas the comparison between rhizomes and leaves showed the differential expression of 423 metabolites, and the comparison between bulblets and rhizomes showed the differential expression of 249 metabolites. The bulblets exhibited 49 metabolites that were higher and 412 metabolites that were lower than those of the leaves, whereas the rhizomes showed 123 upregulated and 300 downregulated metabolites. Bulblets showed an increase in 18 metabolites and a decrease in 231 metabolites compared to the rhizomes. Leaves contain more phenolic acids than the rhizomes and bulblets, whereas the rhizomes and bulblets contain more terpenoids than the leaves. KEGG pathway analysis showed an association between metabolites and metabolic pathways, as well as their effect on the progression and maturation of Oresitrophe rupifraga Bunge. The research findings can provide some insight into the growth and developmental traits of Oresitrophe rupifraga Bunge, thus providing a theoretical foundation for cultivating and utilising this plant.

Abstract
Hepatic ischemia-reperfusion injury (HIRI) is a major complication of liver trauma, resection, and transplantation that can lead to liver dysfunction and failure. Scholars have proposed a variety of liver protection methods aimed at reducing ischemia-reperfusion damage, but there is still a lack of effective treatment methods, which urgently needs to find new effective treatment methods for patients. Many studies have reported that signaling pathway plays a key role in HIRI pathological process and liver function recovery mechanism, among which nuclear transfer factor-κB (NF-κB) signaling pathway is one of the signal transduction closely related to disease. NF-κB pathway is closely related to HIRI pathologic process, and inhibition of this pathway can delay oxidative stress, inflammatory response, cell death, and mitochondrial dysfunction. In addition, NF-κB can also interact with PI3K/Akt, MAPK, and Nrf2 signaling pathways to participate in HIRI regulation. Based on the role of NF-κB pathway in HIRI, it may be a potential target pathway for HIRI. This review emphasizes the role of inhibiting the NF-κB signaling pathway in oxidative stress, inflammatory response, cell death, and mitochondrial dysfunction in HIRI, as well as the effects of related drugs or inhibitors targeting NF-κB on HIRI. The objective of this review is to elucidate the role and mechanism of NF-κB pathway in HIRI, emphasize the important role of NF-κB pathway in the prevention and treatment of HIRI, and provide a theoretical basis for the target NF-κB pathway as a therapy for HIRI.

Klotho-mediated activation of the anti-oxidant Nrf2/ARE signal pathway affects cell apoptosis, senescence and mobility in hypoxic human trophoblasts: involvement of Klotho in the pathogenesis of preeclampsia. Cell Div 2024; 19:13. [PMID: 38632651 PMCID: PMC11025225 DOI: 10.1186/s13008-024-00120-2] [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: 12/05/2023] [Accepted: 04/11/2024] [Indexed: 04/19/2024] Open
Abstract
The anti-aging gene Klotho is implicated in the pathogenesis of preeclampsia (PE), which is a pregnancy disease characterized by hypertension and proteinuria. Oxidative stress is closely associated with the worse outcomes in PE, and Klotho can eliminate Reactive Oxygen Species (ROS), but it is still unclear whether Klotho regulates PE pathogenesis through modulating oxidative damages. Here, by analyzing the clinical data, we found that Klotho was aberrantly downregulated in PE umbilical cord serum and placental tissues, compared to their normal counterparts. In in vitro experiments, the human trophoblasts were subjected to hypoxic pressure to establish the PE models, and we confirmed that hypoxia also decreased the expression levels of Klotho in those trophoblasts. In addition, through performing functional experiments, we confirmed that hypoxia promoted oxidative damages, cell apoptosis and senescence, whereas suppressed cell invasion in human trophoblasts, which were all reversed overexpressing Klotho. The following mechanical experiments verified that Klotho increased the levels of nuclear Nrf2, total Nrf2, SOD2 and NQO1 to activate the anti-oxidant Nrf2/ARE signal pathway, and silencing of Nrf2 abrogated the protective effects of Klotho overexpression on hypoxic human trophoblasts. Consistently, in in vivo experiments, Klotho overexpression restrained oxidative damages and facilitated cell mitosis in PE rats' placental tissues. In conclusion, this study validated that Klotho activated the Nrf2/ARE signal pathway to eliminate hypoxia-induced oxidative damages, cell apoptosis and senescence to recover normal cellular functions in human trophoblasts, and our data supported that Klotho could be used as novel biomarker for PE diagnosis and treatment.

Abstract
Diabetic foot ulcers (DFUs) are a prevalent and profoundly debilitating complication that afflicts individuals with diabetes mellitus (DM). These ulcers are associated with substantial morbidity, recurrence rates, disability, and mortality, imposing substantial economic, psychological, and medical burdens. Timely detection and intervention can mitigate the morbidity and disparities linked to DFU. Nevertheless, current therapeutic approaches for DFU continue to grapple with multifaceted limitations. A growing body of evidence emphasizes the crucial role of cellular senescence in the pathogenesis of chronic wounds. Interventions that try to delay cellular senescence, eliminate senescent cells (SnCs), or suppress the senescence-associated secretory phenotype (SASP) have shown promise for helping chronic wounds to heal. In this context, targeting cellular senescence emerges as a novel therapeutic strategy for DFU. In this comprehensive review, we look at the pathology and treatment of DFU in a systematic way. We also explain the growing importance of investigating SnCs in DFU and highlight the great potential of senotherapeutics that target SnCs in DFU treatment. The development of efficacious and safe senotherapeutics represents a pioneering therapeutic approach aimed at enhancing the quality of life for individuals affected by DFU.

Abstract
Acute lung injury (ALI) is one of the most common complications in COVID-19 and also a syndrome of acute respiratory failure with high mortality rates, but lacks effective therapeutic drugs. Natural products provide inspiration and have proven to be the most valuable source for bioactive molecule discovery. In this study, the chemical evolution of the natural product Tanshinone IIA (Tan-IIA) to achieve a piperidine-fused scaffold through a synthetic route of pre-activation, multi-component reaction, and post-modification is presented. Through biological evaluation, it is pinpointed that compound 8b is a standout candidate with remarkable anti-inflammation and anti-oxidative stress properties, coupled with low toxicity. The mechanistic study unveils a multifaceted biological profile of 8b and shows that 8b is highly efficient in vivo for the treatment of ALI. Therefore, this work not only provides an effective strategy for the treatment of ALI, but also offers a distinctive natural product-inspired drug discovery.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116882. [PMID: 37422100 DOI: 10.1016/j.jep.2023.116882] [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: 04/30/2023] [Revised: 07/03/2023] [Accepted: 07/05/2023] [Indexed: 07/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a traditional Chinese anti-emetic formula, Xiao-Ban-Xia decoction (XBXD) was recorded in Golden Chamber, and has promising anti-emetic effect on chemotherapy-induced nausea and vomiting (CINV). AIM OF THE STUDY This study aimed to determine whether the underlying mechanism of XBXD against CINV is correlated to the restoration of cisplatin-induced PINK1/Parkin mediated mitophagy deficiency and mitigation of gastrointestinal inflammation. MATERIALS AND METHODS The rat pica model was established by intraperitoneal injection of cisplatin 6 mg/kg. The daily kaolin consumption, food intake and body weight were recorded every 24 h. The pathological damage of gastric antrum and ileum were observed by hematoxylin-eosin staining. The levels of serum reactive oxygen species (ROS), interleukin-1β (IL-1β) and interleukin-1β (IL-18) were detected by ELISA. The expression of microtubule-associated protein 1 light chain 3 (LC3) in gastric antrum and ileum was detected by Immunofluorescence staining. The levels of LC3II, P62/SQSTM1, PTEN-induced putative protein kinases (PINK1), E3 ubiquitin ligase (Parkin), AMP-dependent protein kinases (AMPK), phosphorylated AMPK (p-AMPK), nuclear factor erythroid 2-related factor (Nrf2) and kelch like ECH Associated Protein 1 (Keap1) in gastric antrum and ileum were assayed by western blotting. RESULTS At 24 h and 72 h following cisplatin challenge, XBXD inhibited cisplatin-induced elevation of kaolin consumption, and improved the daily food intake and body weight loss in rats. Cisplatin-induced gastrointestinal histopathological damages were alleviated, and serum levels of ROS, IL-1β and IL-18 increases were mitigated following XBXD treatments. In gastric antrum and ileum, XBXD activated AMPK-Nrf2 signaling pathway and restored cisplatin-induced PINK1/Parkin mediated mitophagy deficiency. CONCLUSIONS XBXD significantly ameliorated CINV in a cisplatin-induced rat pica model. The underlying anti-emetic mechanism of XBXD might be related to the activation of AMPK-Nrf2 signaling pathway and the restoration of cisplatin-induced PINK1/Parkin-mediated mitophagy deficiency in the gastrointestinal tract.

Abstract
This research aimed to find important genes and pathways related to cellular senescence (CS) in diabetic foot ulcers (DFU) and to estimate the possible pathways through which CS affects diabetic foot healing. The GSE80178 dataset was acquired from the Gene Expression Omnibus (GEO) database, containing six DFU and three diabetic foot skin (DFS) samples. The limma package was used to identify differentially expressed genes (DEGs). At the same time, DEGs associated with CS (CS-DEGs) were found using the CellAge database. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted on the CS-DEGs. A protein-protein interaction (PPI) network was built using the String database, and the cytoHubba plug-in within Cytoscape helped identify hub genes. Lastly, the miRNA-TF-mRNA regulatory network for these hub genes was established. In total, 66 CS-DEGs were obtained. These genes mainly focus on CS, Kaposi sarcoma-associated herpesvirus infection and Toll-like receptor signalling pathway. Eight hub genes were identified to regulate cell senescence in DFU, including TP53, SRC, SIRT1, CCND1, EZH2, CXCL8, AR and CDK4. According to miRNA-TF-mRNA regulatory network, hsa-mir-132-3p/SIRT1/EZH2 axis is involved in senescence cell accumulation in DFU.

Abstract
Normal tension glaucoma (NTG) is referred to as a progressive degenerative disorder of the retinal ganglion cells (RGCs), resulting in nonreversible visual defects, despite intraocular pressure levels within the statistically normal range. Current therapeutic strategies for NTG yield limited benefits. Excitatory amino acid carrier 1 (EAAC1) knockout (EAAC1-/- ) in mice has been shown to induce RGC degeneration without elevating intraocular pressure, mimicking pathological characteristics of NTG. In this study, we explored whether daily oral administration of melatonin could block RGCs loss and prevent retinal morphology and function defects associated with EAAC1 deletion. We also explored the molecular mechanisms underlying EAAC1 deletion-induced RGC degeneration and the neuroprotective effects of melatonin. Our RNA sequencing and in vivo data indicated EAAC1 deletion caused elevated oxidative stress, activation of apoptosis and cellular senescence pathways, and neuroinflammation in RGCs. However, melatonin administration efficiently prevented these detrimental effects. Furthermore, we investigated the potential role of apoptosis- and senescence-related redox-sensitive factors in EAAC1 deletion-induced RGCs degeneration and the neuroprotective effects of melatonin administration. We observed remarkable upregulation of p53, whereas NRF2 and Sirt1 expression were significantly decreased in EAAC1-/- mice, which were prevented by melatonin treatment, suggesting that melatonin exerted its neuroprotective effects possibly through modulating NRF2/p53/Sirt1 redox-sensitive signaling pathways. Overall, our study provided a solid foundation for the application of melatonin in the management of NTG.

Abstract
Chronic wounds fail to achieve complete closure and are an economic burden to healthcare systems due to the limited treatment options and constant medical attention. Chronic wounds are characterised by dysregulated signalling pathways. Research has focused on naturally derived compounds, stem-cell-based therapy, small molecule drugs, oligonucleotide delivery nanoparticles, exosomes and peptide-based platforms. The phosphoinositide-3-kinase (PI3K)/protein kinase B (AKT), Wingless-related integration (Wnt)/β-catenin, transforming growth factor-β (TGF-β), nuclear factor erythroid 2-related factor 2 (Nrf2), Notch and hypoxia-inducible factor 1 (HIF-1) signalling pathways have critical roles in wound healing by modulating the inflammatory, proliferative and remodelling phases. Moreover, several regulators of the signalling pathways were demonstrated to be potential treatment targets. In this review, the current research on targeting signalling pathways under chronic wound conditions will be discussed together with implications for future studies.
