Markers of beige adipocytes in inguinal adipose tissue. The transcripts for FGF21, P2RX5, PAT2, CITED1, CAR4, TBX1, CD137, and TMEM26 were evaluated in inguinal adipose tissue from mice maintained at room temperature (22 °C) or exposed to cold (5 °C) for one week in 3 separate experiments were the ages of the mice at the end of the experiment were 2 months and 10 days (Exp-1), 2 months and 23 days (Exp-2), and 4 months and 10 days (Exp-3). The levels of the transcripts at 5 °C were normalized to the transcript of the same gene at 22 °C. Values are means ± SEM (n = 4–5). (*) different from 22 °C, p ≤ 0.05, two-tailed t-test
