This study investigated the therapeutic potential of nicotinamide mononucleotide (NMN), a metabolic modulator known to enhance immune cell functionality, in augmenting MSLN CAR-NK cell efficacy against ovarian cancer (OC). Through systematic evaluation, we found that NMN supplementation significantly enhanced CAR-NK cell activation marker expression (CD69, NKG2D), degranulation capacity (CD107a+ increased by 21.7 ± 1.1%), and cytokine production (IFN-γ elevated 1.3-fold). In addition, NMN treatment potentiated MSLN CAR-NK cell-mediated cytotoxicity against MSLN+ target cells, achieving 32.8 ± 1.4% specific lysis at an effector-to-target ratio of 25:1, while concurrently reducing cellular apoptosis compared with controls. Mechanistic interrogation via transcriptomic profiling revealed NMN-mediated modulation of PLC-γ phosphorylation cascades and mitochondrial redox homeostasis. Notably, NMN effectively counteracted tumor microenvironment-induced mitochondrial ROS accumulation (reduced by 25.1 ± 0.8% in OC-conditioned medium). Critically, in an OVCAR8-MSLN xenograft model, adoptive transfer of NMN-preconditioned CAR-NK cells led to superior tumor control, reduced proliferation (Ki67), diminished angiogenesis (CD31), and enhanced intratumoral CAR-NK infiltration compared with controls. These findings establish NMN as a clinically relevant adjuvant that augments CAR-NK cell efficacy through dual mechanisms: metabolic enhancement of effector functions and protection against microenvironmental oxidative suppression, thereby offering a translatable strategy to improve CAR-NK therapy for ovarian cancer.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"33 9","pages":"1081-1091"},"PeriodicalIF":6.4,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148757480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cellular quiescence, reversible exit from the cell cycle, increases chemotherapy resistance as chemotherapies primarily target rapidly proliferating cells. Here, we report that CHD4 and MBD3, components of the nucleosome remodeling and deacetylase (NuRD) complex, are downregulated in quiescent OvCa cells (qOvCa). We find that either CHD4 or MBD3 knockdown or histone deacetylase inhibitors (HDACi), induce quiescence in OvCa cells. RNA-Seq and ATAC-seq analysis of HDACi-treated cells confirmed expression changes consistent with induction of quiescence. Additionally, HDACi-treated cells revealed downregulation of the RHO/RAC pathways. Suggesting downregulation of the RAC pathway could play a role in HDACi-mediated quiescence, RAC inhibitors (RACi) similarly induced quiescence. Both HDACi and RACi resulted in nuclear-to-cytoplasmic shifting of the pro-proliferative transcription factor MRTFA. which has been linked to quiescence. Further analysis of HDACi qOvCa indicated multiple alterations in proteostasis, including increased proteasome activity and autophagy. We find qOvCa cells are dependent on these pathways for survival, such that there is profound synergistic OvCa cell death with HDACi and proteasome- or autophagy-inhibitor combination therapy. Combined, this work supports HDACi as pharmacologic means to induce a quiescent state in OvCa cells and sensitize them to proteostasis-targeting drugs.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"33 9","pages":"1-16"},"PeriodicalIF":6.4,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41417-026-01067-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148764516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this, we integrated comprehensive bioinformatics analyses of The Cancer Genome Atlas (TCGA) dataset with experimental validation to identify PCAT7 as a functionally relevant long non-coding RNA (lncRNA), complemented by functional assays including cell proliferation tests, glucose consumption measurements, and lactate production assays, as well as molecular interaction verification using luciferase reporter assays and RNA immunoprecipitation (RIP). Our results showed that PCAT7 is overexpressed in BRCA tissues and correlates with poor patient prognosis; mechanistically, PCAT7 acts as a molecular sponge for miR-204-5p, alleviating its inhibitory effect on RUNX2 and thereby regulating key glycolytic regulators including GLUT1 and PKM2, while silencing PCAT7 suppresses tumor cell proliferation, invasion, migration, and glycolytic activity in vitro. Collectively, this study uncovers a novel ceRNA network involving PCAT7/miR-204-5p/RUNX2 that drives glycolytic metabolism in BRCA, advancing our understanding of epigenetic regulation in cancer metabolism and highlighting PCAT7 as a potential prognostic biomarker for BRCA patients, with future in vivo studies needed to further validate the therapeutic potential of targeting this axis.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"33 9","pages":"1069-1080"},"PeriodicalIF":6.4,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148705564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the tumorigenic potential of these mutations remains unresolved partly due to the challenges in modeling tumors that arise during early brain development. We and others recently demonstrated that small molecule UM171 mimics KBTBD4 mutations by promoting robust CoREST degradation and expansion of hematopoietic stem cells. Leveraging this mechanistic similarity, we modeled KBTBD4 mutations in hematopoietic stem and progenitor cells (HSPCs) and found that mutants induced expansion of immature stem and progenitor populations and impaired lineage differentiation. High-throughput screening identified HDAC inhibitors as specific agents that disrupt mutant KBTBD4 activity, by preventing interaction with the CoREST complex. Using our HSPC model, we demonstrated that the class I HDAC inhibitor mocetinostat alleviated differentiation defects caused by KBTBD4 mutations. Together, these findings reveal the tumorigenic mechanism of KBTBD4 mutations and uncover therapeutic vulnerabilities that may be exploited for clinical applications.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"33 9","pages":"1092-1098"},"PeriodicalIF":6.4,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41417-026-01068-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148705505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bioinformatic analysis of clinical datasets revealed that CLK3 expression positively correlated with angiogenesis-related pathways in colorectal cancer. In vitro and in vivo experiments confirmed that CLK3 overexpression promoted tumor angiogenesis, whereas CLK3 knockout inhibited this process.
