To explore novel AMPK-interacting proteins and investigate their biological functions, the present study used TurboID proximity labeling in U251 cells stably expressing AMPK-TurboID. Novel AMPK-interacting proteins were explored under both normal and CCCP-treated conditions to investigate their biological functions. Stable cell lines overexpressing AMPK-TurboID were successfully established, and interacting proteins were identified through biotin labeling, silver staining and mass spectrometry analysis. Due to the involvement of AMPK in numerous metabolic pathways and the advantages of TurboID over traditional techniques, including its high temporal resolution, <i>in situ</i> labeling in living cells and its ability to capture weak and transient interactions, a number of proteins interacting with AMPK were identified. Six proteins identified by label-free MS were validated by western blotting, showing that the expression levels of menage a trois-1 and DNAJ heat shock protein family (Hsp40) member A1 (DNAJA1) closely matched the MS data. DNAJA1 was selected for further experimentation. TurboID proximity labeling, affinity purification and LC-MS/MS, western blotting, co-immunoprecipitation (co-IP) and immunofluorescence (IF) techniques demonstrated that AMPK and DNAJA1 not only interact with each other but also synergistically protect cells from apoptosis, perhaps providing a basis for targeted therapeutics (such as treatments for diabetes and myocardial infarction). The present study achieved covalent labeling of endogenous proteins located within nanometer distance of the labeling enzyme by adding a biotin-based substrate. The labeled proteins were then captured and enriched using streptavidin-coated magnetic beads for subsequent identification by MS. These MS results, combined with subsequent validation, led to the identification of DNAJA1 as a key AMPK-interacting protein that synergizes with AMPK to protect cells from apoptosis.</p>","PeriodicalId":94002,"journal":{"name":"Experimental and therapeutic medicine","volume":"31 6","pages":"149"},"PeriodicalIF":2.3,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13096766/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147793011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These organosulfur compounds, particularly allicin and its derivatives such as diallyl disulfide, diallyl trisulfide and ajoene, function through a number of mechanisms, preventing viral entry into host cells by blocking attachment and fusion, inhibiting key viral enzymes required for replication (such as neuraminidase and viral polymerase), and strengthening the innate immune response of the host. However, the clinical application of allicin has been limited by its inherent instability, rapid metabolism and poor bioavailability. To overcome these challenges, researchers are beginning to develop innovative nano-delivery systems using lipid nanoparticles and polymeric carriers that can effectively protect allicin from degradation, improving its solubility and enhancing targeted delivery to infected tissues. Combining the established applications of allicin with nanotechnology advancements represents a promising way to create garlic-based antiviral treatments.

Despite this phenomenon, the mechanisms underlying host cell recovery remain poorly understood. Upon breaching the epithelial barrier, SP primarily targets the pulmonary interstitial cells, which constitute the major mesenchymal component of the lung. These cells serve as essential effectors of tissue repair, extracellular matrix remodeling and epithelial restoration. Therefore, a feline pulmonary interstitial cell (FCA-L2) model of SP infection was established to investigate the protective effects of glutamine (GLU) and fish collagen peptides (FCP) through integrated transcriptomic and metabolomic analyses. Cells were infected with SP (0.05 McFarland units for 4 h) and then treated with doxycycline (7.5 µg/ml for 18 h) followed by GLU (40 mM) or FCP (500 µg/ml). Notably, SP infection increased lactate dehydrogenase (LDH) release by 3.5-fold, induced secretion of IL-1β, TNF-α and IL-8, disrupted tight-junction proteins (claudin, ZO-1 and occludin) and caused oxidative imbalance and apoptosis despite antibiotic (doxycycline) treatment. However, treatment with GLU or FCP significantly reduced LDH release by ~40%, restored junctional proteins, suppressed inflammatory cytokines and enhanced antioxidant enzyme activities. Multi-omics analysis revealed that GLU promoted amino acid biosynthesis and energy metabolism and suppressed aminoacyl-tRNA synthetases and cell-cycle regulators, thereby enhancing metabolic adaptability. By contrast, FCP activated amino and nucleotide sugar metabolism, increased polyunsaturated fatty-acid synthesis and supported glycocalyx repair and membrane reconstruction. GLU and FCP provided complementary metabolic and structural protection, which mitigated post-infectious stress and promoted cellular recovery.

The present retrospective case-control study analyzed preterm infants who underwent ROP screening at Hebei General Hospital (Shijiazhuang, China) between September 2018 and July 2023. Participants were stratified into mild (n=42) and severe ROP (n=38) groups based on fundus examination results and treatment requirements. Demographic characteristics, perinatal complications, maternal third-trimester lipid profiles and serial hematological parameters (within 24 h of birth and at 1 week of age) were analyzed. Binary logistic regression analysis was performed to identify independent risk factors, and receiver operating characteristic (ROC) curves were constructed to evaluate predictive performance. Significant differences were observed between severe and mild ROP groups in gestational age, birth weight and 1-min Apgar score (all P<0.001). Perinatal complications significantly associated with severe ROP included neonatal bronchopulmonary dysplasia (P<0.001), neonatal respiratory distress syndrome (P=0.003), neonatal sepsis (P=0.009) and blood transfusion requirements (P<0.001). Among hematological parameters, lymphocyte-to-monocyte ratio (LMR) was significantly lower in the severe ROP group both within 24 h of birth (P=0.015) and at 1 week of age (P=0.01).
