Activating thermogenic adipose tissues, such as brown adipose tissue and beige adipose tissue, could be a promising strategy to combat obesity and consequently obesity-related diabetes. Both peroxisome proliferator-activated receptor-γ (PPARγ) and retinoid X receptor γ (RXRγ) play significant roles in the regulation of adipogenic differentiation. However, the underlying mechanisms and interactions between these receptors during adipogenic differentiation remain unclear. In this study, we conducted a comprehensive analysis of a transcriptome sequencing dataset sourced from the GEO database, encompassing samples of white and brown adipose tissues from 15 healthy individuals. Our findings reveal that RXRγ expression is significantly elevated in brown adipose tissue relative to white adipose tissue (<i>p</i> = 0.041). Furthermore, co-immunoprecipitation assays validated that RXRγ can be co-precipitated with PPARγ.
