Although rDNA transcription is limited in somatic cells, it is more active in stem cells. Nevertheless, the mechanisms involved in somatic cell reprogramming remain elusive. Both somatic and stem cell nucleoli exhibit a reticular structure. However, under the electron microscope, we identified an intermediate nucleolar state during reprogramming. This state underwent changes characterised by rDNA hypertranscription, resulting in an enlarged nucleolus, enhanced activity of nucleolus organiser regions (NORs), and a transition from the reticular nucleolar type to an intermediate state of reprogramming, whose three liquid phase boundaries are blurred. Our research revealed that Oct4 was directly targeted to the rDNA enhancer region, promoting its hypertranscription and nucleolar enlargement during reprogramming. Using rDNA transcriptional inhibitors, we proved that nucleolar remodelling and subsequent reprogramming are halted by inhibiting rDNA transcription. But why could rDNA transcriptional activity influence reprogramming? Our findings elucidate that the active nucleoli have the capability to release perinucleolar heterochromatin. By joint analysis of Assay for Transposase-Accessible Chromatin with high throughput sequencing (ATAC-seq) and RNA-seq, we have characterised the perinucleolar chromatin released by the nucleolus in a reprogramming intermediate state. The released chromatin mainly impacted mesenchymal-to-epithelial transition (MET)-related genes. MET is a stage of silencing of mesenchymal genes, accompanied by the activation of epithelial genes. Concurrently, the morphology of mouse embryonic fibroblast cells (MEFs) transitions from elongated spindle-shaped cells to short roundish forms, exhibiting a propensity to cluster together. MET was considered an early event in reprogramming; our findings suggested that nucleolar remodelling occurred before MET.","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70052"},"PeriodicalIF":5.9,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143974445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite advancements in gene targeted therapies and immunotherapies, high heterogeneity contributes to limited efficacy and therapeutic resistance. Ubiquitination, a crucial post-translational modification that regulates protein stability and degradation, plays a significant role in cancer pathogenesis by influencing key oncogenic pathways and tumour progression. This review systematically explores the ubiquitin-proteasome system (UPS) and its potential as a therapeutic target for NSCLC. We highlight recent preclinical and clinical studies focusing on ubiquitination-related biomarkers, drug targets and emerging therapies like proteasome inhibitors and Proteolysis-targeting chimeras (PROTACs). By exploring the impact of the UPS on tumour biology, the progression of NSCLC and its response to therapy, we aim to underscore the potential of targeting the ubiquitination-deubiquitination system as a complementary or synergistic approach to existing therapeutic strategies in NSCLC, thereby enhancing patient outcomes and overcoming treatment resistance.","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70050"},"PeriodicalIF":5.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143982192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current treatment methods bring new disease burdens to patients due to postoperative complications and multiple side effects, especially in surface tumours such as oral squamous cell carcinoma (OSCC). In this study, we developed a microwave cold atmospheric plasma (CAP) device in conjunction with tumour microenvironment-responsive nanohydroxyapatite (nHA) for the first time. The synergistic effects of CAP and nHA combined application on OSCC were evaluated in both in vitro and in vivo experiments. The synergistic effects of CAP and pH-responsive NH2-nHA on the apoptosis, intracellular reactive oxygen species (ROS) and calcium ion concentration of OSCC cells were investigated in vitro. The synergistic induction of CAP with NH2-nHA exhibited optimal tumour-specific inhibitory effects on OSCC. The results revealed that the combined application of CAP with NH2-nHA induced apoptosis of tumour cells in vitro and killed 84.0% of tumours in vivo. Mechanistically, CAP enhances extracellular ROS production, while NH2-nHA amplifies intracellular calcium ion (Ca2+) concentrations, synergistically increasing intracellular ROS levels to provoke oxidative stress in OSCC cells, ultimately triggering the mitochondrial apoptosis pathway. In conclusion, the combined utilisation of CAP and NH2-nHA presents a promising avenue as a novel, selective, and non-invasive strategy in the management of OSCC.","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70041"},"PeriodicalIF":5.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143981687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Normalisation of glycolysis metabolism is essential for senescence amelioration. However, the mechanism of proteins involved in cellular glycolysis metabolism has not been fully elucidated. Here, we identified a candidate compound, an oxazole analogue (KB2764), that can improve senescence. To elucidate the mechanism of the KB2764, we investigated the interacting proteins. KB2764 interacted with alpha-enolase (ENO1) and pyruvate kinase M (PKM), ultimately allowing PKM to phosphorylate ENO1. KB2764 consequently increased mitochondrial ATP production and reduced reliance on glycolysis. Knockdown of the ENO1 experiment in senescent cells demonstrates that regulation of ENO1 activity is a prerequisite for recovery of mitochondrial function. Furthermore, the action of KB2764 extends its application to extend the lifespan of Caenorhabditis elegans. Taken together, our findings reveal a novel mechanism by which senescence is ameliorated through metabolic reprogramming and mitochondrial functional recovery via KB2764-mediated regulation of ENO1 protein activity.","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70049"},"PeriodicalIF":5.9,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143969509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its pathogenesis remains incompletely understood, and effective treatment strategies are still lacking. Organoid technology, in which stem cells or progenitor cells self-organise into miniature tissue structures under three-dimensional (3D) culture conditions, provides a promising in vitro platform for simulating the pathological microenvironment of OA. This approach can be employed to investigate disease mechanisms, carry out high-throughput drug screening and facilitate personalised therapies. This review summarises joint structure, OA pathogenesis and pathological manifestations, thereby establishing the disease context for the application of organoid technology. It then examines the components of the arthrosis organoid system, specifically addressing cartilage, subchondral bone, synovium, skeletal muscle and ligament organoids. Furthermore, it details various strategies for constructing OA organoids, including considerations of cell selection, pathological classification and fabrication techniques. Notably, this review introduces the concept of intelligent manufacturing of OA organoids by incorporating emerging engineering technologies such as artificial intelligence (AI) into the organoid fabrication process, thereby forming an innovative software and hardware cluster. Lastly, this review discusses the challenges currently facing intelligent OA organoid manufacturing and highlights future directions for this rapidly evolving field. By offering a comprehensive overview of state-of-the-art methodologies and challenges, this review anticipates that intelligent, automated fabrication of OA organoids will expedite fundamental research, drug discovery and personalised translational applications in the orthopaedic field.","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70043"},"PeriodicalIF":5.9,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143974446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although kynurenic acid (KYNA) has been associated with protective effects against ischemia-reperfusion injury in various organs, the precise mechanisms underlying its protective role in HIRI are not well elucidated. In this study, a 70% mouse HIRI model and an in vitro hypoxia/reoxygenation model were employed to examine the protective effects of KYNA on HIRI. In this study, we illustrate that KYNA influences the methylation status of the Hippo signalling pathway by enhancing the expression of the fat mass and obesity-associated gene (FTO). Within this pathway, large tumour suppressor kinase 1 (LATS1) is identified as a direct target of FTO. Moreover, the stability of LATS1 mRNA exhibits an inverse correlation with FTO levels and is modulated through its interaction with YTH N6-Methyladenosine RNA Binding Protein F2 (YTHDF2). The reduction in LATS1 expression facilitated Yes-associated protein (YAP) nuclear translocation, decreased hepatocyte apoptosis, and mitigated HIRI. Clinically, elevated levels of serum KYNA correlate with a diminished severity of liver injury post-transplantation. our work revealed that KYNA possesses significant clinical translational potential for the prevention of HIRI, and further exploration of its underlying mechanisms was conducted.","PeriodicalId":9760,"journal":{"name":"Cell Proliferation","volume":" ","pages":"e70048"},"PeriodicalIF":5.9,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143967221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
