Abstract
Mitochondria are more than mere energy generators; they are multifaceted organelles that integrate metabolic, signalling, and immune functions, making them indispensable players in maintaining cellular and systemic health. Mitochondrial transfer has recently garnered attention due to its potential role in several physiological and pathological processes. This process involves multiple mechanisms by which mitochondria, along with mitochondrial DNA and other components, are exchanged between cells. In this review, we examine the critical roles of mitochondrial transfer in health and disease, focusing on its impact on immune cell function, the resolution of inflammation, tissue repair, and regeneration. Additionally, we explore its implications in viral infections and cancer progression. We also provide insights into emerging therapeutic applications, emphasizing its potential to address unmet clinical needs.

J Affect Disord 2025; 380:685-695. [PMID: 40180044 DOI: 10.1016/j.jad.2025.03.116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2024] [Revised: 02/16/2025] [Accepted: 03/19/2025] [Indexed: 04/05/2025]
Abstract
BACKGROUND Mitochondrial dysfunction has been implicated in the development of mental disorders, yet the underlying mechanisms remain unclear. In this study, we employed summary-data-based Mendelian randomization (SMR) analysis to explore the associations between mitochondrial-related genes and seven common mental disorders across gene expression, DNA methylation, and protein levels. METHOD Summary statistics from genome-wide association studies were used for seven mental disorders, including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, anxiety, bipolar disorder, major depressive disorder, post-traumatic stress disorder, and schizophrenia (SCZ). Instrumental variables associated with 1136 mitochondria-related genes were derived from summary statistics for DNA methylation, gene expression, and protein quantitative trait loci. SMR analyses and colocalization analyses were then conducted across these three biological levels to explore the associations with each of the seven mental disorders. RESULTS We identified mitochondria-related genes associated with mental disorders with multi-omics evidence: RMDN1 for ADHD, and ACADVL, ETFA, MMAB, and PPA2 for SCZ. Specifically, an increase of one standard deviation in the level of RMDN1 was linked to a 12 % decrease in the risk of developing ADHD (OR = 0.88, 95 % CI: 0.83-0.94). Increased levels of ETFA (OR = 1.79, 95 % CI: 1.24-2.60) and MMAB (OR = 1.10, 95 % CI: 1.05-1.16) were significantly associated with increased risk of SCZ. Conversely, high levels of ACADVL (OR = 0.50, 95 % CI: 0.33-0.77) and PPA2 (OR = 0.68, 95 % CI: 0.55-0.85) were associated with a reduced risk of SCZ. CONCLUSIONS These findings suggested that dysfunction in mitochondria-related genes may underlie the molecular mechanisms of ADHD and SCZ, providing novel biomarkers for diagnosis and therapeutic interventions.

[PMID: 40306112 DOI: 10.1016/j.intimp.2025.114741] [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: 01/05/2025] [Revised: 04/22/2025] [Accepted: 04/23/2025] [Indexed: 05/02/2025]
Abstract
Sepsis-associated acute kidney injury (SA-AKI) is a severe condition with high mortality rates and a lack of specific treatments. Dendrobine (DEN) has shown diverse pharmacological effects across different diseases. Nonetheless, its impact on SA-AKI remains unexplored. This study aimed to investigate DEN's therapeutic potential in SA-AKI and elucidate its mechanism of action. In vivo, SA-AKI models were induced through cecal ligation and puncture or lipopolysaccharide (LPS) administration, while in vitro model was established using LPS-stimulated HK-2 cells. We found that pre-treatment with DEN reduced levels of inflammation-related cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6), and improved kidney function in SA-AKI both in vitro and in vivo. RNA-seq analysis unveiled the critical role of mitophagy in DEN treatment for SA-AKI. We observed an initial increase in mitophagy-related proteins such as PINK1, PARKIN, and LC3B/A, peaking at 8 h post-LPS stimulation, followed by a subsequent decline. Additionally, we demonstrated that DEN upregulated the expression of mitophagy-associated proteins in both in vitro and in vivo SA-AKI models. Notably, we found that carbonyl cyanide 3-chlorophenylhydrazone (CCCP) increased LC3B/A levels in DEN treatment for SA-AKI, whereas Mdivi-1 counteracted the effect of DEN on PINK1, PARKIN, and LC3B/A. These findings demonstrated that DEN enhances mitophagy through the activation of PINK1/PARKIN-mediated pathways, thus mitigating SA-AKI.

Abstract
Hepatocellular carcinoma (HCC) represents a significant global health challenge, characterized by a high incidence rate. Mitochondria have emerged as an important therapeutic target for HCC. Donafenib, a multi-receptor tyrosine kinase inhibitor, has been approved for the treatment of advanced HCC. However, the underlying mechanisms remain to be elucidated. In this study, we aim to investigate the effects of Donafenib on mitochondrial function in HCC cells. Firstly, we show that Donafenib induces mitochondrial oxidative stress in SNU-449 liver cancer cells by increasing mitochondrial ROS while reducing glutathione peroxidase (GPx) activity and the expression of Mn-SOD. We also demonstrate that Donafenib decreases mitochondrial membrane potential (MMP) and induces the opening of the mitochondrial permeability transition pore (mPTP). Furthermore, Donafenib reduces mitochondrial respiratory rate, COX IV activity, and ATP production. Notably, Donafenib induces mitochondrial fragmentation and reduces mitochondrial length by increasing the expression of DRP1, without affecting Mfn1 or Mfn2. Silencing of DRP1 protects against mitochondrial dysfunction induced by Donafenib, indicating that DRP1 plays a key role in mediating Donafenib's effects on mitochondrial function in HCC cells.

Abstract
Mitochondrial metabolism in neurons is necessary for energetically costly processes like synaptic transmission and plasticity. As post-mitotic cells, neurons are therefore faced with the challenge of maintaining healthy functioning mitochondria throughout lifetime. The precise mechanisms of mitochondrial maintenance in neurons, and particularly in morphologically complex dendrites and axons, are not fully understood. Evidence from several biological systems suggests the regulation of cellular metabolism by extracellular vesicles (EVs), secretory lipid-enclosed vesicles that have emerged as important mediators of cell communication. In the nervous system, neuronal and glial EVs were shown to regulate neuronal circuit development and function, at least in part via the transfer of protein and RNA cargo. Interestingly, EVs have been implicated in diseases characterized by altered metabolism, such as cancer and neurodegenerative diseases. Furthermore, nervous system EVs were shown to contain proteins related to metabolic processes, mitochondrial proteins and even intact mitochondria. Here, we present the current knowledge of the mechanisms underlying neuronal mitochondrial maintenance, and highlight recent evidence suggesting the regulation of synaptic mitochondria by neuronal and glial cell EVs. We further discuss the potential implications of EV-mediated regulation of mitochondrial maintenance and function in neuronal circuit development and synaptic plasticity.

Vital Role of PINK1/Parkin-Mediated Mitophagy of Pulmonary Epithelial Cells in Severe Pneumonia Induced by IAV and Secondary Staphylococcus aureus Infection. Int J Mol Sci 2025; 26:4162.

Abstract
Influenza A virus (IAV) infection causes considerable morbidity and mortality worldwide, and the secondary bacterial infection further exacerbates the severity and fatality of the initial viral infection. Mitophagy plays an important role in host resistance to pathogen infection and immune response, while its role on pulmonary epithelial cells with viral and bacterial co-infection remains unclear. The present study reveals that the secondary Staphylococcus aureus infection significantly increased the viral and bacterial loads in human lung epithelial cells (A549) during the initial H1N1 infection. Meanwhile, the secondary S. aureus infection triggered more intense mitophagy in A549 cells by activating the PINK1/Parkin signaling pathway. Notably, mitophagy could contribute to the proliferation of pathogens in A549 cells via the inhibition of cell apoptosis. Furthermore, based on an influenza A viral and secondary bacterial infected mouse model, we showed that activation of mitophagy was conducive to the proliferation of virus and bacteria in the lungs, aggravated the inflammatory damage and severe pneumonia at the same time, and eventually decreased the survival rate. The results elucidated the effect and the related molecular mechanism of mitophagy in pulmonary epithelial cells following IAV and secondary S. aureus infection for the first time, which will provide valuable information for the pathogenesis of virus/bacteria interaction and new ideas for the treatment of severe pneumonia.

Abstract
Mitochondrial dysfunction has emerged as a critical factor in the progression and prognosis of low-grade glioma (LGG). In this study, we explored the role of mitochondrial-related genes through consensus clustering analysis using multi-omics data from the TCGA, CGGA, and other independent datasets. Patients were categorized into three clusters (Cluster A, B, and C), with Cluster B consistently associated with poorer prognosis. Mutation landscape analysis revealed distinct genetic alterations and copy number variations among clusters, particularly in Cluster B, which exhibited unique genetic signatures. Immune infiltration analysis showed that Cluster B had higher expression levels of immune checkpoint genes, stronger immune evasion activity, and greater immune cell infiltration, suggesting an immunosuppressive tumor microenvironment. Furthermore, we identified mitochondrial-related prognostic markers and developed a MITscore based on gene expression patterns, which stratified patients into high- and low-risk groups. High MITscore groups displayed stronger stemness characteristics, poorer survival outcomes, and differential responses to chemotherapy and immunotherapy. Cross-validation with drug sensitivity and immunotherapy cohorts indicated that high MITscore patients were more sensitive to certain chemotherapeutic agents and responded better to immunotherapy. Finally, using the SRGA method, we identified novel biomarkers (KDR, LRRK2, SQSTM1) closely associated with mitochondrial function, which may serve as potential targets for therapeutic intervention. These findings highlight the critical role of mitochondrial dysfunction in LGG prognosis, tumor microenvironment regulation, and treatment response, providing new avenues for precision oncology.

Mitochondrial metabolism-related features guiding precision subtyping and prognosis in breast cancer, revealing FADS2 as a novel therapeutic target. Transl Oncol 2025; 54:102330. [PMID: 39986190 PMCID: PMC11904520 DOI: 10.1016/j.tranon.2025.102330] [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: 10/26/2024] [Revised: 01/27/2025] [Accepted: 02/13/2025] [Indexed: 02/24/2025] Open
Abstract
BACKGROUND Breast cancer is one of the most prevalent malignant tumors in women. Mitochondria, essential for cellular function, have altered metabolic activity in cancer cells, influencing tumor regulation and clinical outcomes. The connection between mitochondrial metabolism-related genes and breast cancer prognosis remains underexplored. This study aims to investigate the role of these genes in breast cancer by constructing risk models. METHODS Breast cancer transcriptome data were obtained from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), and mitochondrial gene data were sourced from the MitoCarta3.01 database. Clustering analysis was conducted using the "ConsensusClusterPlus" package, followed by Gene Set Enrichment Analysis (GSEA), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses. A prognostic model was built using Cox regression and Least Absolute Shrinkage and Selection Operator (LASSO) algorithms. Immune cell infiltration levels were assessed via CIBERSORT and MCPcounter algorithms. Validation of key gene expression was performed on breast cancer tissue specimens and cell models to explore their biological functions in breast cancer cells. RESULTS The LASSO regression analysis of the TCGA BRCA dataset identified four prognosis-related mitochondrial metabolism genes: MYH11, LTF, FADS2, and PSPHP1. Validation using the GEO dataset confirmed that patients with high-risk scores (based on these four genes) had shorter overall survival compared to those with lower risk scores. Immunological analysis revealed that high-risk patients were less responsive to immunotherapy but more sensitive to conventional chemotherapies. This suggests that combining chemotherapy with immunotherapy might enhance T cell-based treatments. Univariate and multivariate Cox regression confirmed that the mitochondrial gene model was an independent predictor of overall survival, and a nomogram was developed to predict patient prognosis. Tissue validation showed consistent expression patterns with bioinformatic predictions. Functional assays confirmed that FADS2 was highly expressed in breast cancer cells, and its knockout significantly reduced cell invasion, migration, and colony formation. CONCLUSION This study reveals that mitochondrial metabolism-related genes are closely associated with breast cancer progression, clinical outcomes, and genetic alterations. The findings may offer new avenues for treatment strategies, early intervention, and prognosis prediction in breast cancer.

Abstract
BACKGROUND Melanoma is the most dangerous type of skin cancer with poor therapy outcomes. Since malignant cells are more susceptible to Ca2+ overload than normal cells, activating Ca2+ overload-mediated apoptosis may be a promising strategy to inhibit melanoma progression. Hydrogen sulfide (H2S) donors can regulate Ca2+ channels, but their effects on melanoma cells remain unclear. OBJECTIVE To explore the effects of Thiotaurine (TTAU), an H2S donor, on melanoma cells and its underlying mechanisms. METHODS We tested the effect of TTAU by culturing melanoma cells in vitro and establishing the xenograft model of mice in vivo. Cell proliferation and apoptosis were assessed using the CCK-8 test and flow cytometry. Molecules involved in apoptosis or Ca2+-related signal transduction were analyzed by western blotting. Immunofluorescence was used to measure Ca2+ levels, mitochondrial damage, and reactive oxygen species (ROS). RESULTS TTAU significantly reduced melanoma cell viability and induced apoptosis both in vitro and in vivo. Mechanistically, TTAU increased intracellular Ca2+, upregulated transient receptor potential vanilloid 1(TRPV1), and decreased activating transcription factor 3(ATF3) by nuclear factor of activated T cell cytoplasmic 1(NFATc1). TTAU also caused mitochondrial damage and ROS overproduction, which also promoted apoptosis. CONCLUSION We first elucidate that TTAU inhibits melanoma progression by activating Ca2+ influx-NFATc1-ATF3 signaling and aggravating mitochondrial oxidative stress, in which TRPV1 may act as an amplifier for Ca2+ influx. Our research is expected to provide new ideas for the treatment of tumors such as melanoma, as well as the clinical application of reactive sulfur species-based drugs.

Abstract
Evidence accumulated mitochondria, as the "powerplants of the cell," express several functional receptors for external ligands that modify their function and regulate cell biology. This review sheds new light on the role of these organelles in sensing external stimuli to facilitate energy production for cellular needs. This is possible because mitochondria express some receptors on their membranes that are responsible for their autonomous responses. This is not surprising given the widely accepted hypothesis that these intracellular organelles originated from prokaryotic ancestors that fused with eukaryotic cells during early evolution. It has been reported that mitochondria express functional estrogen, androgen, glucocorticoid, 5-hydroxytryptamine, melatonin, and cannabinoid receptors. What is intriguing is recent evidence showing that mitochondria could also be directly regulated by active mediators of intracellular complement (complosome) and intrinsic mediators of purinergic signaling. Accordingly, they express receptors for intracellular complement cleavage fragments (C5a and C3a) as well as for adenosine triphosphate (ATP), which, besides its crucial role in transferring energy in the cells, is also an important signaling molecule interacting with P2X7 receptor expressed not only on the cell surface but also on the mitochondria membrane. Based on this, intrinsic complosome and purinergic signaling mediators emerge as important cooperating regulators of reactive oxygen species (ROS) release from mitochondria and activators of intracellular pattern recognition receptor Nlrp3 inflammasome. This activation within the beneficial "hormetic zone response" regulates cell metabolism, proliferation, migration, and adaptation to the surrounding challenges of the microenvironment in a favorable way.

Abstract
Although cisplatin is a widely used chemotherapeutic agent, it is severely toxic and causes irreversible hearing loss, restricting its application in clinical settings. This study aimed to determine the molecular mechanism underlying cisplatin-induced ototoxicity. Here, we established in vitro and in vivo ototoxicity models of cisplatin-induced hair cell loss, and our results showed that reducing STING levels decreased inflammatory factor expression and hair cell death. In addition, we found that cisplatin-induced mitochondrial dysfunction was accompanied by cytosolic DNA, which may act as a critical linker between the cyclic GMP-AMP synthesis-stimulator of interferon genes (cGAS-STING) pathway and the pathogenesis of cisplatin-induced hearing loss. H-151, a specific inhibitor of STING, reduced hair cell damage and ameliorated the hearing loss caused by cisplatin in vivo. This study underscores the role of cGAS-STING in cisplatin ototoxicity and presents H-151 as a promising therapeutic for hearing loss.

Transplantation of gastric epithelial mitochondria into human gastric cancer cells inhibits tumor growth and enhances chemosensitivity by reducing cancer stemness and modulating gastric cancer metabolism. Stem Cell Res Ther 2025; 16:87. [PMID: 39988680 PMCID: PMC11849191 DOI: 10.1186/s13287-025-04223-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2024] [Accepted: 02/11/2025] [Indexed: 02/25/2025] Open
Abstract
BACKGROUND Gastric cancer is the malignant disease. The problems associated with cancer stemness and chemotherapy resistance in gastric cancer therapy remain unresolved. Glucose-regulated protein 78 (GRP78) is a biomarker of gastric cancer and modulates cancer stemness and chemoresistance. Previous studies have shown that mitochondrial transplantation from healthy cells is a promising method for treating various diseases and that the regulation of mitochondrial metabolism is crucial for modulating the stemness and chemoresistance of cancer cells. The aim of this study was to investigate the therapeutic effect of mitochondrial transplantation from normal gastric epithelial cells into gastric cancer and the associated mechanisms. METHODS The expression of cancer stemness markers, intracellular oxidative stress, or apoptotic-related proteins were evaluated via flow cytometry. Western blotting was used to investigate the molecular mechanism involved in MKN45 or AGS human gastric cancer cells after transplantation with human gastric epithelial mitochondria. The mitochondrial metabolic function of gastric cancer cells was determined via a Seahorse bioanalyzer, and extracellular lactate was evaluated via bioluminescent assay. The viability of 5-fluorouracil (5-FU)-treated gastric cancer cells was detected via a CCK-8 assay. Furthermore, a xenograft tumor animal study was performed to validate the therapeutic effects of human gastric epithelial mitochondrial transplantation in gastric cancer. Immunohistochemistry and Western blotting were then used to assess the expressions related to cancer stemness and mitochondrial metabolism-related proteins in tumor tissues. RESULTS Transplanting human gastric epithelial mitochondria downregulates gastric cancer mitochondrial biogenesis, glycolysis, GRP78-mediated cancer stemness, and increases oxidative stress, cell apoptosis under hypoxic conditions and chemosensitivity in response to 5-FU treatment. Moreover, the transplantation of epithelial mitochondria into gastric tumors inhibited the tumor growth in vivo tumor graft animal models. Therefore, mitochondrial transplantation can be considered for the treatment of gastric cancer.

Abstract
The production and weathering processes of nanoparticles (NPs) introduce charged functional groups on their surface. Previous studies have found that the surface charge properties of NPs play a critical role in their toxic effects and the mechanisms are generally attributed to their different accumulations and transmembrane potentials. Currently, we still lack sufficient knowledge about effects, owing to the unique structures of these polymers. In this study, positively charged NPs (PS-NH2, 50 nm) at 0.05-0.5 μg mL-1 promoted the proliferation of hepatic tumors in oncogenic KrasG12V zebrafish larvae and they also increased the viability of human hepatocellular carcinoma cells, whereas negatively charged NPs (PS-COOH, 50 nm) did not. We present evidence indicating that the potential carcinogenicity of PS-NH2 is related to the special polymer-molecular interactions caused by its positive surface charge. The affinity of PS-COOH chains for peptides typically enhances enzyme stability and upregulates its expression. However, PS-NH2 strongly competes with hydrogen bonds of the first rate-limiting enzyme PCK1 in gluconeogenesis, thus downregulating the expression of PCK1 and promoting the aerobic glycolysis pathway, which most tumor cells prefer. This study indicates that positive-charge modified NPs in the environment may bring additional carcinogenic risks.

Abstract
Sepsis is a life-threatening multi-organ dysfunction syndrome caused by dysregulated host response to infection, posing a significant global healthcare challenge. Sepsis-induced myocardial dysfunction (SIMD) is a common complication of sepsis, significantly increasing mortality due to its high energy demands and low compensatory reserves. The substantial mitochondrial damage rather than cell apoptosis in SIMD suggests disrupted cardiac energy metabolism as a crucial pathophysiological mechanism. Therefore, we systematically reviewed the mechanisms underlying energy metabolism dysfunction in SIMD, including alterations in myocardial cell energy metabolism substrates, excitation-contraction coupling processes, mitochondrial dysfunction, and mitochondrial autophagy and biogenesis, summarizing potential therapeutic targets within them.

Abstract
Mitochondrial transplantation is a significant therapeutic approach for addressing mitochondrial dysfunction in patients with spinal cord injury (SCI), yet it is limited by rapid mitochondrial deactivation and low transfer efficiency. Here, high-quality mitochondria microfactories (HQ-Mitofactories) were constructed by anchoring Prussian blue nanoenzymes onto mesenchymal stem cells for effective mitochondrial transplantation to treat paralysis from SCI. Notably, the results demonstrated that HQ-Mitofactories could continuously produce vitality-boosting mitochondria with highly interconnected and elongated network structures under oxidative stress by scavenging excessive ROS. Furthermore, HQ-Mitofactories enabled efficient transfer of therapeutic mitochondria to injured neurons primarily via gap junctions, resulting in the restoration of mitochondrial homeostasis and thereby suppressing intracellular ROS burst and facilitating neuronal repair. After i.v. administration, HQ-Mitofactories migrated to the injured spinal cords of SCI mice and subsequently promoted neuronal regeneration and remyelination. Consequently, HQ-Mitofactory-treated mice successfully recovered locomotor function within 4 weeks, with 40% of the mice fully restoring walking after hindlimb paralysis. Conversely, untreated SCI exhibited completely abolished hindlimb movements. In light of real-time generation of vitality-boosting mitochondria even under oxidative stress and enabling targeted mitochondrial transfer, HQ-Mitofactories have promising therapeutic potential in the context of mitochondrial transplantation to reduce SCI-related paralysis, and more broadly impact the field of neuroregenerative medicine.

Abstract
BACKGROUND Sepsis is a systemic inflammatory syndrome that can cause coagulation abnormalities, leading to damage in multiple organs. Vascular endothelial cells (VECs) are crucial in the development of sepsis-induced coagulopathy (SIC). The role of Parthenolide (PTL) in regulating SIC by protecting VECs remains unclear. METHODS The study utilized septic rats and lipopolysaccharide (LPS)-stimulated VECs to simulate a SIC model and observe the therapeutic effects of PTL. Additionally, nanotechnology was employed to produce Nano-PTL (N-PTL), to observe whether it has advantages over PTL in treating SIC. RESULTS PTL has been shown to mitigate lung injury in septic rats, significantly reduce tumor necrosis factor-α (TNF-α) levels, and increase survival rates. PTL treatment also enhances coagulation function, augments vascular endothelial cell (VEC) function, reduces mitochondrial fragmentation, and increases both mitochondrial oxygen consumption rate (OCR) and mitochondrial membrane potential (MMP), while inhibiting reactive oxygen species (ROS) production. By increasing BRD4/BCL-xL levels, PTL can prevent mitochondrial-mediated apoptosis in VECs, improve VEC function, and consequently ameliorate SIC. Additionally, nanotechnology-synthesized N-PTL further enhances the protective effects on VECs and coagulation function. CONCLUSIONS This study clarifies the therapeutic effects and mechanisms of PTL on SIC, offering new strategies and directions for the treatment of sepsis.

Abstract
Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling. Many mitochondria-transfer mechanisms have been described using a variety of names, generating confusion about mitochondria transfer biology. Furthermore, several therapeutic approaches involving mitochondria-transfer biology have emerged, including mitochondria transplantation and cellular engineering using isolated mitochondria. In this Consensus Statement, we define relevant terminology and propose a nomenclature framework to describe mitochondria transfer and transplantation as a foundation for further development by the community as this dynamic field of research continues to evolve.

Li Y, Qi J, Guo L, Jiang X, He G. Organellar quality control crosstalk in aging-related disease: Innovation to pave the way. Aging Cell 2025; 24:e14447. [PMID: 39668579 PMCID: PMC11709098 DOI: 10.1111/acel.14447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2024] [Revised: 11/04/2024] [Accepted: 12/02/2024] [Indexed: 12/14/2024] Open
Abstract
Organellar homeostasis and crosstalks within a cell have emerged as essential regulatory and determining factors for the survival and functions of cells. In response to various stimuli, cells can activate the organellar quality control systems (QCS) to maintain homeostasis. Numerous studies have demonstrated that dysfunction of QCS can lead to various aging-related diseases such as neurodegenerative, pulmonary, cardiometabolic diseases and cancers. However, the interplay between QCS and their potential role in these diseases are poorly understood. In this review, we present an overview of the current findings of QCS and their crosstalk, encompassing mitochondria, endoplasmic reticulum, Golgi apparatus, ribosomes, peroxisomes, lipid droplets, and lysosomes as well as the aberrant interplays among these organelles that contributes to the onset and progression of aging-related disorders. Furthermore, potential therapeutic approaches based on these quality control interactions are discussed. Our perspectives can enhance insights into the regulatory networks underlying QCS and the pathology of aging and aging-related diseases, which may pave the way for the development of novel therapeutic targets.

Abstract
Epidural fibrosis post laminectomy is the leading cause of failed back surgery syndrome. Little is known about the role and mechanisms of adipose tissues in epidural fibrosis. Here, we found that obese patients were more likely to develop epidural fibrosis after spine surgery. Similarly, obesity led to more progressive epidural fibrosis in a mouse model of laminectomy. Adipocyte-myofibroblast transition (AMT) occurs in epidural scarring. Mechanistically, large extracellular vesicles (EVs) from M2-type macrophages transfer mitochondria into adipocytes and promote AMT by activating the TGF-β and PAI-1 pathways. Blocking the PAI-1 pathway significantly attenuated the transition of adipocytes into myofibroblasts. We conclude that large EVs from macrophages transfer mitochondria to promote AMT in epidural fibrosis.

Abstract
Colorectal cancer refers to malignant tumors occurring in the walls of the colon or rectum. The roles of WD Repeat Domain 12 (WDR12) and mitochondrial ribosome-associated tumor suppressor 4 (MRTO4) genes in colorectal cancer remain unclear. The colorectal cancer dataset GSE113513 configuration file was downloaded from the gene expression omnibus database generated from GPL15207. Differentially expressed genes screening, functional enrichment analysis, gene set enrichment analysis, Weighted Gene Co-expression Network Analysis, construction and analysis of protein-protein interaction networks, survival analysis, and gene expression heatmap plotting were conducted. Comparative toxicogenomics database analysis was performed to find diseases most relevant to core genes. TargetScan was used to screen miRNAs regulating core genes. A total of 3106 differentially expressed genes were identified. According to gene ontology analysis, they mainly enriched in organic acid metabolic processes, condensed chromosome kinetochore, oxidoreductase activity, and cell cycle. In Kyoto encyclopedia of genes and genomes analysis, they primarily concentrated in the cell cycle, TGF-β signaling pathway, Jak-STAT signaling pathway, PI3K-Akt signaling pathway, Ras signaling pathway, TNF signaling pathway, p53 signaling pathway, NF-kB signaling pathway, and WNT signaling pathway. Weighted Gene Co-expression Network Analysis with a soft thresholding power set to 12 generated 29 modules. The protein-protein interaction network identified 6 core genes (DDX27, NAT10, WDR12, DKC1, MRTO4, and NOP56). Survival analysis showed core genes (POSTN, MYH11, LUM, COL6A3, and COL4A1) as risk factors. Gene expression heatmap revealed high expression of core genes (WDR12 and MRTO4) in colorectal samples. Comparative toxicogenomics database analysis linked core genes (WDR12 and MRTO4) with local tumor infiltration, bowel obstruction, abdominal pain, and colorectal neoplasms. WDR12 and MRTO4 genes are highly expressed in colorectal cancer, potentially influencing its progression.

Abstract
Intercellular communication is pivotal in mediating the transfer of mitochondria from donor to recipient cells. This process orchestrates various biological functions, including tissue repair, cell proliferation, differentiation and cancer invasion. Typically, dysfunctional and depolarized mitochondria are eliminated through intracellular or extracellular pathways. Nevertheless, increasing evidence suggests that intercellular transfer of damaged mitochondria is associated with the pathogenesis of diverse diseases. This review investigates the prevalent triggers of mitochondrial damage and the underlying mechanisms of mitochondrial transfer, and elucidates the role of directional mitochondrial transfer in both physiological and pathological contexts. Additionally, we propose potential previously unknown mechanisms mediating mitochondrial transfer and explore their prospective roles in disease prevention and therapy.

Abstract
Oral epithelial dysplasia includes a range of clinical oral mucosal diseases with potentially malignant traits. Dental pulp stem cells (DPSCs) are potential candidates for cell-based therapies targeting various diseases. However, the effect of DPSCs on the progression of oral mucosal precancerous lesions remains unclear. Animal experiments were conducted to assess the effect of human DPSCs (hDPSCs). We measured the proliferation, motility and mitochondrial respiratory function of the human dysplastic oral keratinocyte (DOK) cells cocultured with hDPSCs. Mitochondrial transfer experiments were performed to determine the role mitochondria from hDPSCs in the malignant transformation of DOK cells. hDPSCs injection accelerated carcinogenesis in 4NQO-induced oral epithelial dysplasia in mice. Coculture with hDPSCs increased the proliferation, migration, invasion and mitochondrial respiratory function of DOK cells. Mitochondria from hDPSCs could be transferred to DOK cells, and activated mTOR signaling pathway in DOK cells. Our study demonstrates that hDPSCs activate the mTOR signaling pathway through mitochondrial transfer, promoting the malignant transformation of oral precancerous epithelial lesions.

Abstract
Iron overload is a pathological condition characterized by the abnormal accumulation of iron within the body, which may result from excessive iron intake, disorders of iron metabolism, or specific disease states. This condition can lead to significant health complications and may pose life-threatening risks. The excessive accumulation of iron can induce cellular stress, adversely affecting the structure and function of mitochondria, thereby compromising overall organ function. Given the critical role of mitochondria in cellular metabolism and homeostasis, it is imperative to investigate how mitochondrial dysfunction induced by iron overload contributes to disease progression, as well as to explore mitochondrial-related pathways as potential therapeutic targets for various iron overload disorders. This review examines the mechanisms by which mitochondria are implicated in iron overload-induced damage, including increased oxidative stress, mitochondrial DNA damage, and disruptions in energy metabolism. Additionally, it addresses the relationship between these processes and various forms of programmed cell death, as well as alterations in mitochondrial dynamics. Furthermore, the review discusses strategies aimed at alleviating and mitigating the complications associated with iron overload in patients by targeting mitochondrial pathways.

Abstract
Mitochondria are metabolic and signalling hubs that integrate a plethora of interconnected processes to maintain cell homeostasis. They are also dormant mediators of inflammation and cell death, and with aging damages affecting mitochondria gradually accumulate, resulting in the manifestation of age-associated disorders. In addition to coordinate multiple intracellular functions, mitochondria mediate intercellular and inter-organ cross talk in different physiological and stress conditions. To fulfil this task, mitochondrial signalling has evolved distinct and complex conventional and unconventional routes of horizontal/vertical mitochondrial transfer. In this regard, great interest has been focused on the ability of extracellular vesicles (EVs), such as exosomes and microvesicles, to carry selected mitochondrial cargoes to target cells, in response to internal and external cues. Over the past years, the field of mitochondrial EVs (mitoEVs) has grown exponentially, revealing unexpected heterogeneity of these structures associated with an ever-expanding mitochondrial function, though the full extent of the underlying mechanisms is far from being elucidated. Therefore, emerging subsets of EVs encompass exophers, migrasomes, mitophers, mitovesicles, and mitolysosomes that can act locally or over long-distances to restore mitochondrial homeostasis and cell functionality, or to amplify disease. This review provides a comprehensive overview of our current understanding of the biology and trafficking of MitoEVs in different physiological and pathological conditions. Additionally, a specific focus on the role of mitoEVs in aging and the onset and progression of different age-related diseases is discussed.

Abstract
The triatomine bug Rhodnius prolixus is a hematophagous hemipteran and a primary vector of Trypanosoma cruzi, the causative agent of Chagas' disease (CD), in Central America and Northern South America. Blood-feeding poses significant challenges for hematophagous organisms, particularly due to the release of high doses of pro-oxidant free heme during hemoglobin digestion. In this arthropod, most of the free heme in the gut is aggregated into hemozoin (Hz), an inert and non-oxidative biocrystal. Two major components present in the perimicrovillar membranes (PMM) of triatomine insects have been previously implicated in heme crystallization: lipids and the biochemical marker of the PMM, the enzyme α-glucosidase. In this study, we investigated the role of R. prolixus α-glucosidase isoform G (Rp-αGluG) in heme detoxification and the effects of its knockdown on the insect physiology. The effect of α-glucosidase isoform G (αGluG) knockdown on T. cruzi proliferation and metacyclogenesis was also investigated. Initially, a 3D structure of Rp-αGluG was predicted by comparative modeling and then subjected to molecular docking with the heme molecule, providing in silico support for understanding the process of Hz biocrystallization. Next, adult females of R. prolixus were challenged with RNAi against Rp-αGluG (dsαGluG) to assess physiological and phenotypic changes caused by its knockdown. Our data show that the group challenged with dsαGluG produced less Hz, resulting in more intact hemoglobin available in the digestive tract. These animals also laid fewer eggs, which had a lower hatching rate. In addition, T. cruzi metacyclogenesis was significantly lower in the dsαGluG group. The present work demonstrates the importance of Rp-αGluG in heme detoxification, the digestive and reproductive physiology of R. prolixus, as well as its influence on the life cycle of T. cruzi. Since heme neutralization is a vital process for hematophagous bugs, our study provides useful information for the development of new strategies targeting the Hz formation and potentially affecting the vectorial transmission of Chagas disease.

Abstract
BACKGROUND Disrupted cellular communication, inflammatory responses and mitochondrial dysfunction are consistently observed in late-life depression (LLD). Exosomes (EXs) mediate cellular communication by transporting molecules, including mitochondrial DNA (EX-mtDNA), playing critical role in immunoregulation alongside tumor necrosis factor (TNF). Changes in EX-mtDNA are indicators of impaired mitochondrial function and might increase vulnerability to adverse health outcomes. Our study examined EX-mtDNA levels and integrity, exploring their associations with levels of TNF receptors I and II (TNFRI and TNFRII), and clinical outcomes in LLD. METHODS Ninety older adults (50 LLD and 40 controls (HC)) participated in the study. Blood was collected and exosomes were isolated using size-exclusion chromatography. DNA was extracted and EX-mtDNA levels and deletion were assessed using qPCR. Plasma TNFRI and TNFRII levels were quantified by multiplex immunoassay. Correlation analysis explored relationships between EX-mtDNA, clinical outcomes, and inflammatory markers. RESULTS Although no differences were observed in EX-mtDNA levels between groups, elevated levels correlated with poorer cognitive performance (r = -0.328, p = 0.002) and increased TNFRII levels (r = 0.367, p = 0.004). LLD exhibited higher deletion rates (F(83,1) = 4.402, p = 0.039), with a trend remaining after adjusting for covariates (p = 0.084). Deletion correlated with poorer cognitive performance (r = -0.335, p = 0.002). No other associations were found. LIMITATION Cross-sectional study with a small number of participants from a specialized geriatric psychiatry treatment center. CONCLUSION Our findings suggest that EX-mtDNA holds promise as an indicator of cognitive outcomes in LLD. Additional research is needed to further comprehend the role of EX-mtDNA levels/integrity in LLD, paving the way for its clinical application in the future.

Abstract
Mitochondria transfer is a recently described phenomenon in which donor cells deliver mitochondria to acceptor cells1-3. One possible consequence of mitochondria transfer is energetic support of neighbouring cells; for example, exogenous healthy mitochondria can rescue cell-intrinsic defects in mitochondrial metabolism in cultured ρ0 cells or Ndufs4-/- peritoneal macrophages4-7. Exposing haematopoietic stem cells to purified mitochondria before autologous haematopoietic stem cell transplantation allowed for treatment of anaemia in patients with large-scale mitochondrial DNA mutations8,9, and mitochondria transplantation was shown to minimize ischaemic damage to the heart10-12, brain13-15 and limbs16. However, the therapeutic potential of using mitochondria transfer-based therapies to treat inherited mitochondrial diseases is unclear. Here we demonstrate improved morbidity and mortality of the Ndufs4-/- mouse model of Leigh syndrome (LS) in multiple treatment paradigms associated with mitochondria transfer. Transplantation of bone marrow from wild-type mice, which is associated with release of haematopoietic cell-derived extracellular mitochondria into circulation and transfer of mitochondria to host cells in multiple organs, ameliorates LS in mice. Furthermore, administering isolated mitochondria from wild-type mice extends lifespan, improves neurological function and increases energy expenditure of Ndufs4-/- mice, whereas mitochondria from Ndufs4-/- mice did not improve neurological function. Finally, we demonstrate that cross-species administration of human mitochondria to Ndufs4-/- mice also improves LS. These data suggest that mitochondria transfer-related approaches can be harnessed to treat mitochondrial diseases, such as LS.

[PMID: 39218420 DOI: 10.1016/j.phrs.2024.107382] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2024] [Revised: 08/08/2024] [Accepted: 08/26/2024] [Indexed: 09/04/2024]
Abstract
It is now recognized that tumors are not merely masses of transformed cells but are intricately interconnected with healthy cells in the tumor microenvironment (TME), forming complex and heterogeneous structures. Recent studies discovered that cancer cells can steal mitochondria from healthy cells to empower themselves, while reducing the functions of their target organ. Mitochondrial transfer, i.e. the intercellular movement of mitochondria, is recently emerging as a novel process in cancer biology, contributing to tumor growth, metastasis, and resistance to therapy by shaping the metabolic landscape of the tumor microenvironment. This review highlights the influence of transferred mitochondria on cancer bioenergetics, redox balance and apoptotic resistance, which collectively foster aggressive cancer phenotype. Furthermore, the therapeutic implications of mitochondrial transfer are discussed, emphasizing the potential of targeting these pathways to overcome drug resistance and improve treatment efficacy.

Carcinoma-associated mesenchymal stem cells promote ovarian cancer heterogeneity and metastasis through mitochondrial transfer. Cell Rep 2024; 43:114551.

Abstract
Ovarian cancer is characterized by early metastatic spread. This study demonstrates that carcinoma-associated mesenchymal stromal cells (CA-MSCs) enhance metastasis by increasing tumor cell heterogeneity through mitochondrial donation. CA-MSC mitochondrial donation preferentially occurs in ovarian cancer cells with low levels of mitochondria ("mito poor"). CA-MSC mitochondrial donation rescues the phenotype of mito poor cells, restoring their proliferative capacity, resistance to chemotherapy, and cellular respiration. Receipt of CA-MSC-derived mitochondria induces tumor cell transcriptional changes leading to the secretion of ANGPTL3, which enhances the proliferation of tumor cells without CA-MSC mitochondria, thus amplifying the impact of mitochondrial transfer. Donated CA-MSC mitochondrial DNA persisted in recipient tumor cells for at least 14 days. CA-MSC mitochondrial donation occurs in vivo, enhancing tumor cell heterogeneity and decreasing mouse survival. Collectively, this work identifies CA-MSC mitochondrial transfer as a critical mediator of ovarian cancer cell survival, heterogeneity, and metastasis and presents a unique therapeutic target in ovarian cancer.

Abstract
Mitochondrial dysregulation plays a significant role in the carcinogenesis. On the other hand, its destabilization strongly represses the viability and metastatic potential of cancer cells. Photodynamic and photothermal therapies (PDT and PTT) target mitochondria effectively, providing innovative and non-invasive anticancer therapeutic modalities. Cyanine dyes, with strong mitochondrial selectivity, show significant potential in enhancing PDT and PTT. The potential and limitations of cyanine dyes for mitochondrial PDT and PTT are discussed, along with their applications in combination therapies, theranostic techniques, and optimal delivery systems. Additionally, novel approaches for sonodynamic therapy using photoactive cyanine dyes are presented, highlighting advances in cancer treatment.

Abstract
Several cardiovascular illnesses are associated with aberrant activation of cellular pyroptosis, ferroptosis, necroptosis, cuproptosis, disulfidptosis, and macrophage polarisation as hallmarks contributing to vascular damage and abnormal cardiac function. Meanwhile, these three novel forms of cellular dysfunction are closely related to mitochondrial homeostasis. Mitochondria are the main organelles that supply energy and maintain cellular homeostasis. Mitochondrial stability is maintained through a series of regulatory pathways, such as mitochondrial fission, mitochondrial fusion and mitophagy. Studies have shown that mitochondrial dysfunction (e.g., impaired mitochondrial dynamics and mitophagy) promotes ROS production, leading to oxidative stress, which induces cellular pyroptosis, ferroptosis, necroptosis, cuproptosis, disulfidptosis and macrophage M1 phenotypic polarisation. Therefore, an in-depth knowledge of the dynamic regulation of mitochondria during cellular pyroptosis, ferroptosis, necroptosis, cuproptosis, disulfidptosis and macrophage polarisation is necessary to understand cardiovascular disease development. This paper systematically summarises the impact of changes in mitochondrial dynamics and mitophagy on regulating novel cellular dysfunctions and macrophage polarisation to promote an in-depth understanding of the pathogenesis of cardiovascular diseases and provide corresponding theoretical references for treating cardiovascular diseases.

Abstract
Understanding the pathophysiology of long COVID is one of the most intriguing challenges confronting contemporary medicine. Despite observations recently made in the relevant molecular, cellular, and physiological domains, it is still difficult to say whether the post-acute sequelae of COVID-19 directly correspond to the consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This work hypothesizes that neutrophils and neutrophil extracellular traps (NETs) production are at the interconnection of three positive feedback loops which are initiated in the acute phase of SARS-CoV-2 infection, and which involve inflammation, immunothrombosis, and autoimmunity. This phenomenon could be favored by the fact that SARS-CoV-2 may directly bind and penetrate neutrophils. The ensuing strong neutrophil stimulation leads to a progressive amplification of an exacerbated and uncontrolled NETs production, potentially persisting for months beyond the acute phase of infection. This continuous self-stimulation of neutrophils leads, in turn, to systemic inflammation, micro-thromboses, and the production of autoantibodies, whose significant consequences include the persistence of endothelial and multiorgan damage, and vascular complications.

Abstract
Mitochondria are complex organelles with an outer membrane enveloping a second inner membrane that creates a vast matrix space partitioned by pockets or cristae that join the peripheral inner membrane with several thin junctions. Several micrometres long, mitochondria are generally close to 300 nm in diameter, with membrane layers separated by a few tens of nanometres. Ultrastructural data from electron microscopy revealed the structure of these mitochondria, while conventional optical microscopy revealed their extraordinary dynamics through fusion, fission, and migration processes but its limited resolution power restricted the possibility to go further. By overcoming the limits of light diffraction, Super-Resolution Microscopy (SRM) now offers the potential to establish the links between the ultrastructure and remodelling of mitochondrial membranes, leading to major advances in our understanding of mitochondria's structure-function. Here we review the contributions of SRM imaging to our understanding of the relationship between mitochondrial structure and function. What are the hopes for these new imaging approaches which are particularly important for mitochondrial pathologies?

Abstract
Objectives Elevated circulating DNA (cirDNA) concentrations were found to be associated with trauma or tissue damage which suggests involvement of inflammation or cell death in post-operative cirDNA release. We carried out the first prospective, multicenter study of the dynamics of cirDNA and neutrophil extracellular trap (NETs) markers during the perioperative period from 24 h before surgery up to 72 h after curative surgery in cancer patients. Methods We examined the plasma levels of two NETs protein markers [myeloperoxidase (MPO) and neutrophil elastase (NE)], as well as levels of cirDNA of nuclear (cir-nDNA) and mitochondrial (cir-mtDNA) origin in 29 colon, prostate, and breast cancer patients and in 114 healthy individuals (HI). Results The synergistic analytical information provided by these markers revealed that: (i) NETs formation contributes to post-surgery conditions; (ii) post-surgery cir-nDNA levels were highly associated with NE and MPO in colon cancer [r = 0.60 (P < 0.001) and r = 0.53 (P < 0.01), respectively], but not in prostate and breast cancer; (iii) each tumor type shows a specific pattern of cir-nDNA and NETs marker dynamics, but overall the pre- and post-surgery median values of cir-nDNA, NE, and MPO were significantly higher in cancer patients than in HI. Conclusion Taken as a whole, our work reveals the association of NETs formation with the elevated cir-nDNA release during a cancer patient's perioperative period, depending on surgical procedure or cancer type. By contrast, cir-mtDNA is poorly associated with NETs formation in the studied perioperative period, which would appear to indicate a different mechanism of release or suggest mitochondrial dysfunction.

Abstract
Intercellular mitochondrial transfer (MT) is a newly discovered form of cell-to-cell signalling involving the active incorporation of healthy mitochondria into stressed/injured recipient cells, contributing to the restoration of bioenergetic profile and cell viability, reduction of inflammatory processes and normalisation of calcium dynamics. Recent evidence has shown that MT can occur through multiple cellular structures and mechanisms: tunneling nanotubes (TNTs), via gap junctions (GJs), mediated by extracellular vesicles (EVs) and other mechanisms (cell fusion, mitochondrial extrusion and migrasome-mediated mitocytosis) and in different contexts, such as under physiological (tissue homeostasis and stemness maintenance) and pathological conditions (hypoxia, inflammation and cancer). As Mesenchimal Stromal/ Stem Cells (MSC)-mediated MT has emerged as a critical regulatory and restorative mechanism for cell and tissue regeneration and damage repair in recent years, its potential in stem cell therapy has received increasing attention. In particular, the potential therapeutic role of MSCs has been reported in several articles, suggesting that MSCs can enhance tissue repair after injury via MT and membrane vesicle release. For these reasons, in this review, we will discuss the different mechanisms of MSCs-mediated MT and therapeutic effects on different diseases such as neuronal, ischaemic, vascular and pulmonary diseases. Therefore, understanding the molecular and cellular mechanisms of MT and demonstrating its efficacy could be an important milestone that lays the foundation for future clinical trials.

Abstract
We examined from a large exploratory study cohort of COVID-19 patients (N = 549) a validated panel of neutrophil extracellular traps (NETs) markers in different categories of disease severity. Neutrophil elastase (NE), myeloperoxidase (MPO), and circulating nuclear DNA (cir-nDNA) levels in plasma were seen to gradually and significantly (p < 0.0001) increase with the disease severity: mild (3.7, 48.9, and 15.8 ng/mL, respectively); moderate (9.8, 77.5, and 27.7 ng/mL, respectively); severe (11.7, 99.5, and 29.0 ng/mL, respectively); and critical (13.1, 110.2, and 46.0 ng/mL, respectively); and are also statistically different with healthy individuals (N = 140; p < 0.0001). All observations made in relation to the Delta variant-infected patients are in line with Omicron-infected patients. We unexpectedly observed significantly higher levels of NETs in asymptomatic individuals as compared to healthy subjects (p < 0.0001). Moreover, the balance of cir-nDNA and circulating mitochondrial DNA level was affected in COVID-19 infected patients attesting to mitochondrial dysfunction.

Abstract
Mitochondria are important for maintaining cellular energy metabolism and regulating cellular senescence. Mitochondrial DNA (mtDNA) encodes subunits of the OXPHOS complexes which are essential for cellular respiration and energy production. Meanwhile, mtDNA variants have been associated with the pathogenesis of neurodegenerative diseases, including MELAS, for which no effective treatment has been developed. To alleviate the pathological conditions involved in mitochondrial disorders, mitochondria transfer therapy has shown promise. Wharton's jelly mesenchymal stem cells (WJMSCs) have been identified as suitable mitochondria donors for mitochondria-defective cells, wherein mitochondrial functions can be rescued. Miro1 participates in mitochondria trafficking by anchoring mitochondria to microtubules. In this study, we identified Miro1 over-expression as a factor that could help to enhance the efficiency of mitochondrial delivery. More specifically, we reveal that Miro1 over-expressed WJMSCs significantly improved intercellular communications, cell proliferation rates, and mitochondrial membrane potential, while restoring mitochondrial bioenergetics in mitochondria-defective fibroblasts. Furthermore, Miro1 over-expressed WJMSCs decreased rates of induced apoptosis and ROS production in MELAS fibroblasts; although, Miro1 over-expression did not rescue mtDNA mutation ratios nor mitochondrial biogenesis. This study presents a potentially novel therapeutic strategy for treating mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS), and other diseases associated with dysfunctional mitochondria, while the pathophysiological relevance of our results should be further verified by animal models and clinical studies.

Abstract
Bladder cancer (BC) is the ninth most-common cancer worldwide and it is associated with high morbidity and mortality. Mitochondrial Dysfunction is involved in the progression of BC. This study aimed to developed a novel diagnostic model based on mitochondria-related genes (MRGs) for BC patients using Machine Learning. In this study, we analyzed GSE13507 datasets and identified 752 DE-MRGs in BC specimens. Functional enrichment analysis uncovered the significant roles of 752 DE-MRGs in key processes such as cellular and organ development, as well as gene regulation. The analysis revealed the crucial functions of these genes in transcriptional regulation and protein-DNA interactions. Then, we performed LASSO and SVM-RFE, and identified four critical diagnostic genes including GLRX2, NMT1, OXSM and TRAF3IP3. Based on the above four genes, we developed a novel diagnostic model whose diagnostic value was confirmed in GSE13507, GSE3167 and GSE37816 datasets. Moreover, we reported the expressing pattern of GLRX2, NMT1, OXSM and TRAF3IP3 in BC samples. Immune cell infiltration analysis revealed that the four genes were associated with several immune cells. Finally, we performed RT-PCR and confirmed NMT1 was highly expressed in BC cells. Functional experiments revealed that knockdown of NMT1 suppressed the proliferation of BC cells. Overall, we have formulated a diagnostic potential that offered a comprehensive framework for delving into the underlying mechanisms of BC. Before proceeding with clinical implementation, it is essential to undertake further investigative efforts to validate its diagnostic effectiveness in BC patients.

Abstract
Osteoarthritis is a common joint disease characterized by damage to the joint cartilage that occurs throughout the entire joint tissue. This damage primarily manifests as pain in the affected area. In clinical practice, medication is commonly used to relieve pain, but the treatment's effectiveness is poor and recurrent attacks are likely. Schisandrin B is the most abundant biphenylcyclohexene lignan found in the traditional Chinese medicine Schisandra chinensis, and it possesses various pharmacological effects. This study aims to investigate the protective effect of Schisandrin B on mitochondrial damage in osteoarthritis (C28I2 cells) under an inflammatory environment induced by LPS. Cell proliferation and activity, scratch tests, and LDH release tests are utilized to assess cell growth and migration ability. The immunofluorescence assay was used to detect the expression levels of proliferation and apoptosis proteins. The Western Blot assay was used to detect the expression levels of mitochondrial fusion and division proteins. The JC-1 assay was used to detect changes in mitochondrial membrane potential. The mitochondrial fluorescence probe assay was used to detect mitochondrial activity. Through research, it was found that Schisandrin B promotes the proliferation, growth, and migration of C28I2 cells, reduces apoptosis of C28I2 cells, balances mitochondrial fusion and division, stabilizes mitochondrial membrane potential, and promotes mitochondrial activity in an LPS induced inflammatory environment.

Abstract
From the moment a cell is on the path to malignant transformation, its interaction with other cells from the microenvironment becomes altered. The flow of molecular information is at the heart of the cellular and systemic fate in tumors, and various processes participate in conveying key molecular information from or to certain cancer cells. For instance, the loss of tight junction molecules is part of the signal sent to cancer cells so that they are no longer bound to the primary tumors and are thus free to travel and metastasize. Upon the targeting of a single cell by a therapeutic drug, gap junctions are able to communicate death information to by-standing cells. The discovery of the importance of novel modes of cell-cell communication such as different types of extracellular vesicles or tunneling nanotubes is changing the way scientists look at these processes. However, are they all actively involved in different contexts at the same time or are they recruited to fulfill specific tasks? What does the multiplicity of modes mean for the overall progression of the disease? Here, we extend an open invitation to think about the overall significance of these questions, rather than engage in an elusive attempt at a systematic repertory of the mechanisms at play.

Abstract
Bladder cancer (BC) is the fourth and tenth most common malignancy in men and women worldwide, respectively. The complexity of the molecular biological mechanism behind BC is a major contributor to the lack of effective treatment management of the disease. The development and genesis of BC are influenced by mitochondrial retrograde control and mitochondria-nuclear cross-talk. However, the role of mitochondrial-related genes in BC remains unclear. In this study, we analyzed TCGA datasets and identified 752 DE-MRGs in BC samples, including 313 down-regulated MRGs and 439 up-regulated MRGs. Then, the results of machine-learning screened four critical diagnostic genes, including GLRX2, NMT1, PPP2R2B and TRAF3IP3. Moreover, we analyzed their prognostic value and confirmed that only PPP2R2B was associated with clinical prognosis of BC patients and Cox regression assays validated that PPP2R2B expression was a distinct predictor of overall survival in BC patients. Them, we performed RT-PCR and found that PPP2R2B expression was distinctly decreased in BC specimens and cell lines. Functional experiments revealed that overexpression of PPP2R2B distinctly suppressed the proliferation, migration and invasion of BC cells via Wnt signaling pathway. In summary, these research findings offer potential molecular markers for the diagnosis and prognosis of BC, with the discovery of PPP2R2B particularly holding significant biological and clinical significance. This study provides valuable clues for future in-depth investigations into the molecular mechanisms of BC, as well as the development of new diagnostic markers and therapeutic targets.

Abstract
Introduction: NBP is a compound isolated from celery seeds, which was approved by the National Medical Products Administration in 2002 for clinical treatment of ischemic stroke. However, in brain ischemia/reperfusion (I/R) injury, the related research on mitochondrial dynamics and its mechanism of action of NBP still need to be further studied. The aim of this study was to assess NBP on cerebral pathology in ischemic stroke in vivo, with a specific focus on the molecular mechanisms of how NBP promotes mitochondrial fusion. Methods: Male C57BL/6 mice were utilized in this study and were subjected to middle cerebral artery occlusion/reperfusion (MCAO/R). Pre-ischemia, NBP was administered through intraperitoneal (i.p.) injection for 7 days. Results: Our findings demonstrated that NBP effectively reduced infarct volume, improved neurological dysfunction, enhanced cerebral blood flow, and promoted mitochondrial fusion in mice subjected to MCAO/R. More importantly, the pro-fusion effects of NBP were found to be linked to the activation of AMPK/Mfn1 pathway, and with the activation of neurological function, which was partially eliminated by inhibitors of AMPK. Discussion: Our results revealed that NBP is a novel mitochondrial fusion promoter in protecting against ischemic stroke through the AMPK-mediated Mfn1. These findings contribute to the understanding of novel mechanisms involved in the protection of neurological function following NBP treatment for ischemic stroke.

Abstract
Gynecologic tract melanoma is a malignant tumor with poor prognosis. Because of the low survival rate and the lack of a standard treatment protocol related to this condition, the investigation of the mechanisms underlying melanoma progression is crucial to achieve advancements in the relevant gynecological surgery and treatment. Mitochondrial transfer between adjacent cells in the tumor microenvironment regulates tumor progression. This study investigated the effects of endothelial mitochondria on the growth of melanoma cells and the activation of specific signal transduction pathways following mitochondrial transplantation. Mitochondria were isolated from endothelial cells (ECs) and transplanted into B16F10 melanoma cells, resulting in the upregulation of proteins associated with tumor growth. Furthermore, enhanced antioxidation and mitochondrial homeostasis mediated by the Sirt1-PGC-1α-Nrf2-HO-1 pathway were observed, along with the inhibition of apoptotic protein caspase-3. Finally, the transplantation of endothelial mitochondria into B16F10 cells promoted tumor growth and increased M2-type macrophages through Nrf2/HO-1-mediated pathways in a xenograft animal model. In summary, the introduction of exogenous mitochondria from ECs into melanoma cells promoted tumor growth, indicating the role of mitochondrial transfer by stromal cells in modulating a tumor's phenotype. These results provide valuable insights into the role of mitochondrial transfer and provide potential targets for gynecological melanoma treatment.

Abstract
Due to their beneficial effects in an array of diseases, Mesenchymal Stromal Cells (MSCs) have been the focus of intense preclinical research and clinical implementation for decades. MSCs have multilineage differentiation capacity, support hematopoiesis, secrete pro-regenerative factors and exert immunoregulatory functions promoting homeostasis and the resolution of injury/inflammation. The main effects of MSCs include modulation of immune cells (macrophages, neutrophils, and lymphocytes), secretion of antimicrobial peptides, and transfer of mitochondria (Mt) to injured cells. These actions can be enhanced by priming (i.e., licensing) MSCs prior to exposure to deleterious microenvironments. Preclinical evidence suggests that MSCs can exert therapeutic effects in a variety of pathological states, including cardiac, respiratory, hepatic, renal, and neurological diseases. One of the key emerging beneficial actions of MSCs is the improvement of mitochondrial functions in the injured tissues by enhancing mitochondrial quality control (MQC). Recent advances in the understanding of cellular MQC, including mitochondrial biogenesis, mitophagy, fission, and fusion, helped uncover how MSCs enhance these processes. Specifically, MSCs have been suggested to regulate peroxisome proliferator-activated receptor-gamma coactivator 1 alpha (PGC1α)-dependent biogenesis, Parkin-dependent mitophagy, and Mitofusins (Mfn1/2) or Dynamin Related Protein-1 (Drp1)-mediated fission/fusion. In addition, previous studies also verified mitochondrial transfer from MSCs through tunneling nanotubes and via microvesicular transport. Combined, these effects improve mitochondrial functions, thereby contributing to the resolution of injury and inflammation. Thus, uncovering how MSCs affect MQC opens new therapeutic avenues for organ injury, and the transplantation of MSC-derived mitochondria to injured tissues might represent an attractive new therapeutic approach.
