Similarly, in cancer, it acts as a tumor suppressor by downregulating various oncogenes and signaling pathways involved in cancer progression, such as Wnt–β-catenin, p38–mitogen-activated protein kinase and nuclear factor-κB. However, the upregulation of these pathways suppresses miR-29b, contributing to fibrosis and cancer development.

Through controlling the balance of the cellular methionine (MET) metabolite pool, MET adenosyl transferase 2 alpha (MAT2A) regulates crucial steps during metabolism and the epigenetic control of transcription. The aberrant function of MAT2A has been shown to drive malignant transformation through metabolic addiction, transcriptional rewiring, and immune modulation of the tumor microenvironment (TME). Moreover, MAT2A sustains the survival of 5′-methylthioadenosine phosphorylase (MTAP)-deficient tumors, conferring synthetic lethality to cancers with MTAP loss, a genetic alteration that occurs in ∼15% of all cancers. Thus, the pharmacological inhibition of MAT2A is emerging as a desirable therapeutic strategy to combat tumor growth. Here, we review the latest insights into MAT2A biology, focusing on its roles in both metabolic addiction and gene expression modulation in the TME, outline the current landscape of MAT2A inhibitors, and highlight the most recent clinical developments and opportunities for MAT2A inhibition as a novel anti-tumor therapy.</div></div>","PeriodicalId":301,"journal":{"name":"Drug Discovery Today","volume":"29 11","pages":"Article 104189"},"PeriodicalIF":6.5,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142277768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
