Herein, via a CRISPR/Cas9 library screen, the effects of ferroptosis agonists were increased in KRAS-mutant PC cells upon knockout of tropomodulin 3 (TMOD3), while these effects were not observed in KRAS-wild-type cells. Increased levels of TMOD3 were found in PC tissues, particularly in those with KRAS mutations. The increase in TMOD3 expression was facilitated by KRAS via the ETS transcription factor ELK1. Liquid chromatography–mass spectrometry (LC/MS) showed that TMOD3 increased acyl-CoA synthetase long chain family member 4 (ACSL4) protein expression and fatty acid metabolism. Mechanistically, TMOD3 promoted F-actin polymerization, thereby facilitating the fusion of autophagosomes with lysosomes, increasing the degradation of the ACSL4 protein, and augmenting the ferroptosis-inducing effects of RSL3. These effects of TMOD3 were counteracted by the administration of cytochalasin, the removal of the α2 domain of TMOD3, or the introduction of a mutation at S71. Cangrelor, an FDA-approved drug, can target TMOD3. In a mouse model, the suppression of TMOD3 using cangrelor or gene silencing technology resulted in increased infiltration of CD8+ T cells into tumor tissues with KRAS mutations and exhibited a synergistic effect with the PD-1 antibody. In conclusion, TMOD3 was found to inhibit ferroptosis and induced the resistance to PD-1 antibody by facilitating the fusion of autophagosomes and lysosomes through the promotion of F-actin polymerization in KRAS-mutant PC. TMOD3 was identified as a novel target for PC therapy.</div></div>","PeriodicalId":51022,"journal":{"name":"Drug Resistance Updates","volume":"78 ","pages":"Article 101171"},"PeriodicalIF":15.8,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142632056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ongoing development of small molecules targeting PRMTs has resulted in the generation of chemical probes for modulating most PRMTs and facilitated clinical treatment for the most advanced oncology targets, including PRMT1 and PRMT5. In this review, we summarize various mechanisms underlying protein arginine methylation and the roles of specific PRMTs in driving cancer drug resistance. Furthermore, we highlight the potential clinical implications of PRMT inhibitors in decreasing cancer drug resistance. PRMTs promote the formation and maintenance of drug-tolerant cells via several mechanisms, including altered drug efflux transporters, autophagy, DNA damage repair, cancer stem cell-related function, epithelial-mesenchymal transition, and disordered tumor microenvironment. Multiple preclinical and ongoing clinical trials have demonstrated that PRMT inhibitors, particularly PRMT5 inhibitors, can sensitize cancer cells to various anti-cancer drugs, including chemotherapeutic, targeted therapeutic, and immunotherapeutic agents. Combining PRMT inhibitors with existing anti-cancer strategies will be a promising approach for overcoming anti-cancer drug resistance.

Therefore, inhibiting the proliferation and growth of RAIR-DTC with multikinase inhibitors and other drugs or restoring its differentiation and then carrying out radioiodine therapy have become the first-line treatment strategies and main research directions. The drugs that regulate these kinases or signaling pathways have been studied in clinical and preclinical settings. In this review, we summarized the major gene mutations, gene rearrangements and abnormal activation of signaling pathways that led to radioiodine resistance of RAIR-DTC, as well as the medicine that have been tested in clinical and preclinical trials.</p></div>","PeriodicalId":51022,"journal":{"name":"Drug Resistance Updates","volume":"72 ","pages":"Article 101013"},"PeriodicalIF":24.3,"publicationDate":"2023-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1368764623000961/pdfft?md5=ea36196d0d2fa25a8ef3b2b8f13f4d5a&pid=1-s2.0-S1368764623000961-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71506790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
