摘要: Summary Autosomal dominant polycystic kidney disease (ADPKD) is a common monogenic disorder marked by numerous progressively enlarging cysts. Mettl3, methyltransferase that catalyzes the abundant N6-methyladenosine (m6A) RNA modification, implicated in development, but its role most diseases unknown. Here, we show Mettl3 and m6A levels are increased mouse human ADPKD samples kidney-specific transgenic expression produces tubular Conversely, deletion three orthologous models slows cyst growth. Interestingly, methionine S-adenosylmethionine (SAM) also elevated models. Moreover, SAM induce aggravate ex vivo growth, whereas dietary restriction attenuates ADPKD. Finally, activates cyst-promoting c-Myc cAMP pathways through enhanced Avpr2 mRNA modification translation. Thus, promotes links utilization to epitranscriptomic activation of proliferation
