From: Plasticity of adipose tissue in response to fasting and refeeding in male mice
Effects of fasting on mitochondrial biogenesis and expression of thermogenesis-related genes in various adipose tissues. Representative transmission electron microscopy (TEM) images of various adipose tissues of adult mice fed ad libitum (a-d) or 24 h-fasting (e-h) mice (arrows indicate mitochondria). Scale bar, 2 μm. Mitochondrial numbers were decreased in ingWAT and iBAT, but increased in eWAT and mWAT after 24 h of fasting compared with the control (i). Differential expressions of mitochondrial biogenesis related gene (Pgc-1α) and thermogenic gene (Ucp-1) in various depots from ad libitum fed or fasted mice (j) were observed (n = 6). All data are presented as the mean ± SEM. * p < 0.05; ** p < 0.01; *** p < 0.001
