Implication

Narrative review uncovers FTO-driven m6A demethylation mechanisms in metabolic tissues, highlighting targeted pathways for treating obesity, fatty liver, and atherosclerosis.

Key Points

To delineate the molecular mechanisms by which FTO-mediated mRNA m6A demethylation regulates lipid metabolism, adipogenesis, and associated metabolic disorders.
Synthesized molecular and pathway-level evidence on FTO-catalyzed RNA m6A demethylation affecting mRNA processing, maturation, and translation.
Analyzed tissue-specific downstream effects across the liver, adipose tissue, skeletal muscle, and macrophages.
Hepatic FTO overexpression enhances lipogenesis and lipid droplet enlargement via SREBP1c while suppressing CPT-1-dependent fatty acid oxidation, driving nonalcoholic fatty liver disease.
Adipocytic FTO promotes preadipocyte differentiation and fat accumulation via C/EBPβ, PPARγ, and RUNX1T1 splicing, while simultaneously blocking lipolysis through IRX3 and leptin inhibition.
FTO diminishes muscle lipid utilization via PPARβ/δ and AMPK suppression, yet conversely restrains atherosclerosis by decreasing macrophage lipid uptake and stimulating AMPK-mediated cholesterol efflux.
