A mouse model of OSA was established with high\u2010fat diet feeding and chronic intermittent hypoxia (CIH) treatment. The histological alterations of epididymal white adipose tissue (eWAT) were evaluated. The effects and mechanisms of methyltransferase\u2010like 14 (METTL14) on regulating macrophage polarization were determined by in\u00a0vitro assays. The global m\n                    <jats:sup>6<\/jats:sup>\n                    A RNA methylation levels and the expression levels of m\n                    <jats:sup>6<\/jats:sup>\n                    A methylation regulators were altered in OSA patients. The mRNA expression level of METTL14 was negatively associated with systemic inflammation parameters. CIH treatment aggravated the infiltration of macrophages in the eWAT of mice. The mRNA and protein levels of METTL14 were downregulated in the eWAT of mice treated with CIH and in hypoxia\u2010treated THP\u20101 macrophages. Overexpression of METTL14 was able to inhibit hypoxia\u2010induced M1 macrophage polarization and restore the M1\/M2 balance. Mechanistically, METTL14 overexpression mediated JAK2 m\n                    <jats:sup>6<\/jats:sup>\n                    A RNA methylation and promoted the decay of JAK2 mRNA, leading to the inhibition of the JAK2\/STAT3 signaling pathway.
