Researcher at Zhejiang University School of Medicine Targets Obesity (Activation of METTL3 promotes white adipose tissue beiging and combats obesity)

Article Description

The induction of beige adipocytes in white adipose tissue (WAT), also known as WAT beiging, improves glucose and lipid metabolism. However, the regulation of WAT beiging at the posttranscriptional level remains to be studied. Here, we report that METTL3, the methyltransferase of N6-methyladenosine (m6A) mRNA modification, is induced during WAT beiging in mice. Adiposespecific depletion of the Mettl3 gene undermines WAT beiging and impairs the metabolic capability of mice fed with a high-fat diet. Mechanistically, METTL3-catalyzed m6A installation on thermogenic mRNAs, including Kr€uppellike factor 9 (Klf9), prevents their degradation. Activation of the METTL3 complex by its chemical ligand methyl piperidine- 3-carboxylate promotes WAT beiging, reduces body weight, and correctsmetabolic disorders in diet-induced obesemice. These findings uncover a novel epitranscriptionalmechanism inWAT beiging and identifyMETTL3 as a potential therapeutic target for obesity-associated diseases.
