[¹⁸F]FDG SUV_peak within interscapular BAT of fasted male mice after NE injection. SUV_peak is plotted for each genotype. Means (short) and standard deviations (long) for each group are represented by horizontal gray bars. With fasting, a statistically significant difference between male WT (blue) and KO (white) SUV_peak was observed (p = 0.03). However, the WT and KO SUV_peak ranges still overlapped and a clear SUV threshold to differentiate animals with very different thermogenic capacity cannot be established, despite animal fasting
