| description | The coexistence of brown adipocytes with low and high thermogenic activity is a fundamental feature of brown adipose tissue (BAT) heterogeneity and plasticity. However, the mechanisms that govern thermogenic adipocyte heterogeneity and its significance in obesity and metabolic disease remain poorly understood. Here we show that in male mice, a population of JunB-enriched (JunB+) adipocytes within the BAT exhibits lower thermogenic capacity compared to high-thermogenic adipocytes. To determine if JunB plays a role in the control of brown adipocyte heterogeneity in thermogenesis, we performed single-nucleus RNA sequencing (snRNA-seq) of BAT from JunB FKO and control mice (3-month-old male mice (5/group)) housed at room temperature. Our study pointing to a potent inhibition by JunB in the conversion from low- to high-thermogenic adipocyte. The nuclei was isolated from newly collected brown fat tissue of 10-week-old JunB deficient and control mice (n=5/group). The same number of nuclei from each individual animal were combined within a group and used for snRNAseq. |
