To assess RYGB efficacy, a T2DM model was induced in rats, with Grin3a knockdown, and AMPK activation. Metabolic parameters, insulin resistance, lipid profiles, adipose tissue morphology, and mitochondrial function in epididymal white adipose tissue (eWAT) were examined. The influence of Grin3a on lipid metabolism and the CaMKK\u03b2\/AMPK axis was evaluated in\u00a0vitro using 3T3\u2010L1 adipocytes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Bioinformatic analyses revealed that Grin3a was diminished in visceral adipose tissue of obese or diabetic models and up\u2010regulated following RYGB. Its expression was associated with lipid metabolism and oxidative phosphorylation pathways. In\u00a0vivo, RYGB restored Grin3a levels and improved insulin sensitivity, lipid profiles, mitochondrial function, and adipose browning, while Grin3a knockdown attenuated these effects and AMPK activation partially reversed them. In\u00a0vitro, Grin3a regulated lipid metabolism and mitochondrial function in adipocytes via the CaMKK\u03b2\/AMPK pathway.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
