BACKGROUND:Neuroinflammation is a critical aspect of aging and neurodegenerative disorders, increasingly recognized for its significant role in the progression of cognitive impairments. Mitochondrial homeostasis is closely linked to cognitive function in the aging brain. However, it remains unclear whether exercise can safeguard cognitive function by enhancing mitochondrial homeostasis in the aged hippocampus affected by neuroinflammation. METHODS:In this study, we established mouse models exhibiting memory impairment and neuroinflammation in the aged hippocampus to investigate whether exercise can reverse lipopolysaccharides (LPS)-induced cognitive dysfunction in aged mice, reduce neuroinflammation, and simultaneously improve mitochondrial homeostasis in the hippocampus. Eighteen-month-old male ICR mice underwent 8 weeks of moderate-intensity aerobic exercise. RESULTS:The exercise regimen enhanced memory function in LPS-injected aged mice, which was accompanied by reductions in inflammation, oxidative stress, and apoptosis in the aged hippocampus. Importantly, exercise improved mitochondrial homeostasis in the hippocampus of LPS-injected aged mice. CONCLUSION:our results provide the first evidence that exercise can protect cognitive function in the context of neuroinflammation in the aged hippocampus, suggesting that this effect may be associated with the improvement of mitochondrial homeostasis.
Growing evidence suggests that exercise can provide neuroprotection by improving mitochondrial quality control (MQC) on the aged brain. Adenosine 5 '-monophosphate (AMP)-activated protein kinase (AMPK) signaling responsiveness declines with aging. However, whether AMPK plays a role in the exercise-mediated improvement of memory and MQC in the aged hippocampus remains to be established. 5-Aminoimidazole 4-carboxamide ribonucleoside (AICAR), a pharmacological agonist of AMPK, has been proposed to be an exercise mimetic recently. However, it has not been clarifi ed whether AICAR could mimic the eff ects of exercise on the aged hippocampus through improvement of MQC. In this study, AICAR (AMPK agonist) and Compound C (AMPK inhibitor) were used to investigate if AMPK plays a key role in exercise-induced improvement of MQC and if AICAR could act as an exercise mimetic through improvement of MQC in aged hippocampus. Both exercise and AICAR improved the memory of aged mice and increased AMPK phosphorylation in the aged hippocampus. Exercise, but not AICAR, improved mitochondrial respiratory function in the aged hippocampus and increased the microtubule associated protein 1 light chain 3 (LC3)-II/LC3-I ratio and the protein expression of LC3-II and autophagy related protein 7 (ATG7) in the lysate of whole hippocampal tissue. Both exercise and AICAR increased the ratio of LC3-II/LC3-I and the protein expression of LC3-II in the mitochondrial fractions of the hippocampus. Regarding mitochondrial dynamics, neither exercise training nor AICAR changed the protein level of mitofusin 2 (Mfn2). Exercise, but not AICAR, increased the protein level of dynamin-related protein 1 (Drp1). Furthermore, both exercise training and AICAR increased the protein level of peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1 alpha), a modulator of mitochondrial biogenesis. Compound C abolished the exercise-induced effects on memory in aged mice, AMPK phosphorylation, autophagy, mitophagy, and mitochondrial fi ssion in the aged hippocampus. However, Compound C did not reverse the exercise-induced increase in PGC-1 alpha protein levels in the aged hippocampus. Our data provide evidence that AMPK plays an important role in the exercise-induced improvement of memory and MQC in the hippocampus of aged mice. Importantly, we demonstrated for the fi rst time that AICAR could partially mimetic the benefi cial eff ects of endurance exercise on memory and MQC in the hippocampus of aged mice, and thus may be a promising exercise mimetic for counteracting brain aging.
ObjectiveThe Mediterranean diet (MD), a widely recognized healthy dietary pattern, has demonstrated significant value in the prevention and management of metabolic syndrome (MetS). However, quantitative integrated analyses of its mechanisms of action remain scarce, highlighting an urgent need for systematic collation.MethodsThis study retrieved relevant literature published between 2015 and 2025 from the Web of Science and Scopus databases, and conducted visual bibliometric analyses using R software (Bibliometrix package), VOSviewer, and CiteSpace.ResultsA total of 1723 valid articles were identified from the Web of Science, and 1061 from Scopus. The number of publications steadily increased from 2015 to 2022, with a particularly notable growth spurt between 2016 and 2018, followed by a slight decline from 2022 to 2024. Spain led significantly in the number of publications, followed by Italy, the United States, and Iran, and Spain has established an extensive international cooperation network. At the journal level, Nutrients serves as the core academic platform in this field, ranking first in both publication volume and citation frequency. Current research hotspots primarily focus on the regulatory effects of MD on blood glucose homeostasis, insulin sensitivity, lipid metabolism, and blood pressure in MetS patients, as well as the mechanisms by which bioactive components (e.g., polyphenols, unsaturated fatty acids, and vitamins) promote metabolic health through anti-inflammatory, antioxidant, and insulin-sensitizing pathways. Gut microbiota modulation has evolved into an emerging research direction in this domain.ConclusionOver the past decade, interdisciplinary research on MD and MetS has gained increasing attention and is expected to become a core focus in the non-pharmacological intervention of MetS. This study systematically clarifies the research status, hot topics, and developmental context of this field, providing important references for future precision nutrition mechanism research and clinical intervention trials.
Background Dysregulation of mitochondrial dynamics, including fusion/fission, transport, mitophagy and biogenesis, plays a crucial role in neurodegenerative diseases. However, a systematic quantitative mapping of the knowledge structure (i.e., key research themes, foundational references, and citation/collaboration clusters) and evolving research trends (i.e., research hotspots over time) in this research field is lacking. Methods Empirical and review article on mitochondrial dynamics in neurodegenerative diseases, which published in English from 2005 to 2025, were retrieved from the Web of Science Core Collection and Scopus. BibliometriX, VOSviewer, and CiteSpace were applied to perform the bibliometric analysis and science mapping. Scientific performance analyses, collaborative networks of authors/institutions/countries, reference co-citation networks, keyword bursts analysis were conducted. Results A total of 834 documents were included, revealing a rapid growth in scientific productivity from 2005 to 2025. The United States, China, and Germany were the most productive countries, with institutions such as Case Western Reserve University and Texas Tech University serving as major hubs. Co-citation and keyword burst analyses reveal a distinct temporal shift: from foundational studies of fusion/fission machinery and oxidative stress toward an integrated Mitochondrial Quality Control paradigm encompassing mitophagy, dynamics, and biogenesis. Key emerging hotspots include mitochondrial biogenesis, mitochondrial transport, and quality control mechanisms. Translational frontiers prioritize enhancing PINK1/Parkin-mediated mitophagy, inhibiting Drp1-driven excessive fission, and activating PGC-1α-dependent biogenesis. Conclusion This bibliometric study maps the intellectual structure and evolutionary trajectory of mitochondrial dynamics research in neurodegenerative diseases. It documents a field-wide paradigm shift toward a translational agenda centered on the MQC framework. Furthermore, the findings highlight the necessity of integrating pharmacological interventions with lifestyle modifications and precision medicine approaches to overcome translational barriers and develop effective disease-modifying strategies.
Ischemic stroke (IS) continues to be a major contributor to global mortality and long - term disability. Buyang Huanwu Decoction (BHD), a traditional Chinese medicine formula, has shown effectiveness in reducing brain injury and promoting post - stroke recovery through experimental researches and clinical trials. The neuroprotective mechanisms of BHD against cerebral ischemic injury involve multiple pathways, such as suppression of inflammation, reduction of oxidative stress, inhibition of apoptosis, regulation of autophagy, and enhancement of mitochondrial function. Moreover, BHD presents therapeutic potential by boosting neuroplasticity, enhancing angiogenesis, reducing excitotoxicity, optimizing brain energy metabolism, and regulating gut microbiota. Considering the current scarce effective treatments for IS, exploring BHD’s therapeutic potential and its mechanism holds substantial clinical significance. This review systematically organizes recent research advancements on BHD’s application in IS management and its underlying mechanisms, providing useful insights for future research and clinical practice.
Nicotinamide adenine dinucleotide (NAD+) is a crucial coenzyme involved in catalyzing cellular redox reactions and serving as a substrate for NAD+-dependent enzymes. It plays a vital role in maintaining tissue homeostasis and promoting healthy aging. Exercise, a well-established and cost-effective method for enhancing health, can influence various pathways related to NAD+ metabolism. Strategies such as supplementing NAD+ precursors, modulating NAD+ synthesis enzymes, or inhibiting enzymes that consume NAD+ can help restore NAD+ balance and improve exercise performance. Various overlapping signaling pathways are known to play a crucial role in the beneficial effects of both NAD+ and exercise on enhancing health and slowing aging process. Studies indicate that a combined strategy of exercise and NAD+ supplementation could synergistically enhance athletic capacity. This review provides an overview of current research on the interactions between exercise and the NAD+ network, underscoring the significance of NAD+ homeostasis in exercise performance. It also offers insights into enhancing exercise capacity and improving aging-related diseases through the optimal use of exercise interventions and NAD+ supplementation methods.
Obesity impairs the health and regeneration of skeletal muscle. Astaxanthin (AX) possesses antioxidant and anti-obesity properties, making it possible to improve obesity-associated damages. 42 male C57BL/6J mice were fed a control diet, a high-fat diet (HFD) or a HFD with 0.02 %AX for 16 weeks. Mice were either immediately euthanized (experiment one) or given intramuscular injections of cardiotoxin (CTX) and euthanized on the seventh day (experiment two). The experiment one showed that AX improved grip strength and motor function with reduced fat deposition and elevated SOD in skeletal muscle. The experiment two found that AX increased the expression of proteins related to muscle regeneration and mitochondrial biogenesis. The in vitro experiment of interfering C2C12 myogenic cells with AX suggested that AX promoted myoblast differentiation and mitochondrial biogenesis. In conclusion, astaxanthin improves skeletal muscle health and regeneration in obese mice induced by HFD.
Exercise is known to be an effective intervention for depression. NADPH has been demonstrated to have neuroprotective effects in our previous studies. This study aimed to investigate if NADPH has antidepressant effects and can mimic the effects of exercise in a chronic unpredictable stress (CUS) rat model. CUS rats underwent an 8week swimming exercise (30 min/d, 5d/w) or were intraperitoneally administered 4 mg/kg or 8 mg/kg NADPH. The open field test (OFT), sucrose preference test (SPT), novelty-suppressed feeding test (NSFT), and forced swimming test (FST) were used to examine the antidepressant-like behaviors of the rats. Exercise, 4 mg/kg, and 8 mg/kg NADPH similarly reduced anxiety, as demonstrated by the number of fecal pellets. Meanwhile, exercise and 8 mg/kg NADPH significantly increased locomotion activity in the OFT. Exercise, 4 mg/kg, and 8 mg/kg NADPH effectively reversed CUS-induced anhedonia in rats in the SPT. Exercise, 4 mg/kg, and 8 mg/kg NADPH had no impact on appetite of depressed rats; however, 8 mg/kg NADPH increased the rats' exploratory activity in the NSFT. Exercise, 4 mg/kg, and 8 mg/kg NADPH significantly reduced the immobility time of CUS model rats, while exercise and 8 mg/kg NADPH postponed the early CUS-induced "immobility" in the FST. These results demonstrated that NADPH has similar antidepressant-like effects to exercise in CUS-induced depression model rats and is a potential exercise-mimicking antidepressant.
Lung adenocarcinoma is a highly aggressive subtype of lung cancer with a high mortality rate, which makes the investigation of novel lung adenocarcinoma therapeutic targets essential. Since oxidative stress has been shown to be a cancer-specific deplete in the lung, which is highly associated with oxidative stress, it is crucial to investigate and assess the clinical value of oxidative stress-related target genes in lung adenocarcinoma. In the current study, we obtained 3170 differentially expressed genes via differential analysis and 1058 oxidative stress-related genes via the molecular signatures database. Upon analyzing their intersection, 207 genes were identified. tRNA-histidine guanylyltransferase 1 like protein, glutathione peroxidase 8, and mitogen-activated protein kinase 3 were identified as lung adenocarcinoma biomarkers using machine learning algorithms. The tumor immune infiltrating analysis revealed that the tRNA-histidine guanylyltransferase 1 like protein gene is associated with the infiltration of regulatory T cells. In addition, the multivariate analysis revealed that elevated tRNA-histidine guanylyltransferase 1 like protein expression is a significant, independent predictor of overall survival. Furthermore, the pan-cancer analysis revealed that elevated tRNA-histidine guanylyltransferase 1 like protein expression is related to a worse prognosis in a variety of cancers. In light of these findings, the identification of tRNA-histidine guanylyltransferase 1 like protein as a novel biological marker may shed light on potential function mechanisms and the impact of the immune microenvironment in lung adenocarcinoma.
Evidence from clinical studies and preclinical studies supports that exercise preconditioning can not only reduce the risk of stroke but also improve brain tissue and functional outcome after stroke. It has been demonstrated that autophagy and mitochondrial dynamics are involved in ischemic stroke. However, it is still unclear whether exercise preconditioning-induced neuroprotection against stroke is associated with modulation of autophagy and mitochondrial dynamics. Although age and sex interactively affect ischemic stroke risk, incidence, and outcome, studies based on young male animals are most often used to explore the role of exercise preconditioning in the prevention of ischemic stroke. In the current study, we examined whether exercise preconditioning could modulate autophagy and mitochondrial dynamics in a brain ischemia and reperfusion (I/R) model of female aged mice. The results showed that exercise preconditioning reduced infarct volume and improved neurological deficits. Additionally, increased levels of autophagy-related proteins LC3-II/LC3-I, LC3-II, p62, Atg7, and mitophagy-related proteins Bnip3L and Parkin, as well as increased levels of mitochondrial fusion modulator Mfn2 and mitochondrial fission modulator Drp1 in the ischemic cortex of female aged mice at 12 h after I/R were present. Our results could contribute to a better understanding of exercise preconditioning-induced neuroprotection against ischemic stroke for the elderly.
BACKGROUND:Mitochondrial autophagy, the elimination of damaged mitochondria through autophagy, contributes to neuron survival in cerebral ischemia. Long non-coding RNAs (lncRNAs)/microRNAs (miRNAs)/mRNAs are important regulatory networks implicated in various biological processes, including cerebral ischemia-reperfusion (I/R) injury. Therefore, this work clarifies a novel RGD1564534-mediated regulatory network on mitochondrial autophagy in cerebral I/R injury.METHODS:Differentially expressed lncRNAs in cerebral I/R injury were predicted by bioinformatics analysis. Expression of RGD1564534 was examined in the established middle cerebral artery occlusion (MCAO) rats and oxygen glucose deprivation/reoxygenation (OGD/R)-exposed neurons. We conducted luciferase activity, RNA pull-down and RIP assays to illustrate the interaction among RGD1564534, miR-101a-3p and Dusp1. Gain- or loss-of-function approaches were used to manipulate RGD1564534 and Dusp1 expression. The mechanism of RGD1564534 in cerebral I/R injury was evaluated both in vivo and in vitro.RESULTS:RGD1564534 was poorly expressed in the MCAO rats and OGD/R-treated cells, while its high expression attenuated nerve damage, cognitive dysfunction, brain white matter and small vessel damage in MCAO rats. In addition, RGD1564534 promoted mitochondrial autophagy and inhibited NLRP3 inflammasome activity. RGD1564534 competitively bound to miR-101a-3p and attenuated its binding to Dusp1, increasing the expression of Dusp1 in neurons. By this mechanism, RGD1564534 enhanced mitochondrial autophagy, reduced NLRP3 inflammasome activity and suppressed the neuron apoptosis induced by OGD/R.CONCLUSION:Altogether, RGD1564534 elevates the expression of Dusp1 by competitively binding to miR-101a-3p, which facilitates mitochondrial autophagy-mediated inactivation of NLRP3 inflammasome and thus retards cerebral I/R injury.
