Cold stimulation not only activates the thermogenesis activity of brown adipose tissue (BAT) but also induces browning of white adipose tissue (WAT). To elucidate the mechanisms underlying cold-induced thermogenesis and adipose tissue remodeling, we used RNA sequencing (RNA-seq) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) to examine the transcriptomic and proteomic profiles, respectively, of adipose tissue from mice exposed to cold or thermoneutral temperature. The male C57BL/6J mice were divided into three groups (5 mice/group), two groups were kept at 6 ˚C for 6 h and 24 h, respectively, and the control group were kept at 22 ˚C for 24 h. Subsequently, the BAT and inguinal WAT of each mouse were dissected and subjected to RNA-seq and data-independent acquisition (DIA)-based LC-MS/MS.
