Oncogenic drivers such as KRAS, c-Myc, and HIF-1α increase how much glutamine gets taken up and broken down. Meanwhile, the bacteria in the gut and tumor itself also affect how much glutamine is available throughout the body and near the tumor. This impacts both how the tumor grows and how the immune system can detect and respond to it. Multiple strategies have emerged to disrupt this dependence: glutamine antagonists (DON and its prodrugs DRP-104, JHU-083), small-molecule glutaminase inhibitors (CB-839), antibody–drug conjugates targeting the ASCT2 transporter, and combination regimens pairing glutamine blockade with immune checkpoint inhibitors. Nanoparticle formulations—including pH-sensitive and PEGylated liposomes co-delivering DON and gemcitabine—enable targeted delivery and reduce off-target toxicity. Single-agent treatments do not work so well because the cells can adapt. They boost enzymes such as asparagine synthetase and increase how they burn fatty acids to make up for the lack of glutamine. To overcome these escape routes, future interventions must concurrently target compensatory pathways and integrate biomarker-driven patient selection. Combining glutamine-targeted agents with inhibitors of asparagine synthesis or lipid oxidation, guided by multi-omics profiling, promises a more durable therapeutic benefit and lays the groundwork for personalized treatment of PDAC.</p>","PeriodicalId":15226,"journal":{"name":"Journal of Cell Communication and Signaling","volume":"19 3","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ccs3.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144589549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SIRT2 was found to deacetylate NF-κB p65, inhibiting NLRP3 activation and reducing inflammatory cytokines. SIRT2 overexpression enhanced chondrocyte proliferation, DNA repair, and mitochondrial function while decreasing reactive oxygen species production. In vivo, SIRT2 significantly improved cartilage repair in OA mice with NLRP3 overexpression attenuating its protective effects.

Primary mouse knee chondrocytes were separated, cultured, and challenged with IL-1β to establish in vitro KOA models. Cell viability was determined, Reactive oxygen species levels and ferroptosis-related factors were measured after interventions with NSD1, krüppel-like factor 9 (KLF9), and acyl-CoA synthetase long-chain family member 4 (ATG14). Furthermore, the enrichment of NSD1 and H3K36me2 on the KLF9 promoter as well as the enrichment of KLF9 on the ATG14 promoter was analyzed. Binding site between KLF9 and ATG14 promoter was assessed. NSD1 was downregulated in KOA mouse cartilage tissues and IL-1β-challenged chondrocytes. KOA severity was alleviated, chondrocyte viability was promoted, and ferroptosis was quenched after NSD1 overexpression. NSD1 strengthened H3K36me2 to upregulate KLF9 expression, and KLF9 transcriptionally activated ATG14 expression. KLF9 or ATG14 knockdown could both partially reverse the protective role of NSD1 overexpression on KOA cartilage ferroptosis.
