KDM6B and obesity due to melanocortin 4 receptor deficiency: In vitro leptin exposure enhanced CCL2 expression/secretion and increased KDM6A/KDM6B and EP300 transcription, highlighting how obesity‐driven epigenetic mechanisms, including leptin‐mediated pathways, disrupt ASC plasticity and perpetuate adipose tissue dysfunction, offering novel therapeutic targets for metabolic disease intervention.
