Mitochondrial dysfunction in renal tubular epithelial cells (TECs) plays a crucial role in the progression of CKD.

In mice with hypertensive CKD induced by AngII (angiotensin II) infusion, renal mtDNA 6mA levels significantly increased, while 5-methylcytosine levels remained stable. METTL4 (methyltransferase-like protein 4), the only known mammalian methyltransferase for 6mA, was upregulated in the renal tubules of hypertensive CKD mice and patients with hypertension. AngII stimulation increased METTL4 expression and mtDNA 6mA levels in primary TECs. Activated c-Jun/AP-1 (activator protein-1) directly promoted Mettl4 transcription in AngII-treated primary TECs. METTL4-catalyzed mtDNA 6mA impeded mitochondrial transcription initiation complex assembly, thereby halting mtDNA transcription, disrupting mitochondrial function, and resulting in the transition of TECs into a proinflammatory and profibrotic phenotype. TEC-specific Mettl4 gene deletion in mice exhibited reduced mtDNA 6mA, preserved mtDNA transcription, improved tubular mitochondrial function, and alleviation of hypertensive CKD.CONCLUSIONSThis study reveals that METTL4-catalyzed mtDNA 6mA contributes to renal mitochondrial dysfunction and hypertensive CKD, offering novel therapeutic strategies from the perspective of mitochondrial epigenetics.","PeriodicalId":13042,"journal":{"name":"Hypertension","volume":"24 1","pages":""},"PeriodicalIF":8.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652794","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}
