Current treatment strategies have limited efficacy in improving patient survival. Metabolic reprogramming is a hallmark of cancer and plays a key role in the pro-gression and maintenance of PC. PC cells exhibit a unique glutamine metabolism that is dis-tinct from other cancer types. The non-classical pathway of glutamine metabolic reprogram-ming plays a \"permissive role\" in the survival and proliferation of PC cells, mainly by affect-ing the redox homeostasis of the cells. In this review, we compare and contrast the canonical and non-canonical glutamine metabolic pathways and highlight recent advances in targeting non-canonical glutamine metabolism for therapeutic intervention. This may provide novel in-sights and opportunities for exploiting glutamine metabolic reprogramming in PC treatment.</p>","PeriodicalId":10816,"journal":{"name":"Current cancer drug targets","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143022499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
