Muscle-dependent regulation of adipose tissue function in long-lived growth hormone-mutant mice

Figure 2. Expression of UCP1 in adipose tissue of Snell Dwarf mice (dw). (A) RNA was isolated from brown fat, mesenteric, inguinal and perigonadal adipose tissues of 24-week-old littermate control (WT) mice and Snell Dwarf mice (dw). mRNA levels of UCP1 were measured by qRT-PCR. Data (mean ± SEM; n = 4) were normalized by the amount of GAPDH mRNA and expressed relative to the corresponding male WT value. *P < 0.05 versus WT. (B) Cell lysate was prepared from brown fat, inguinal and perigonadal adipose tissues of 24-week-old WT and dw mice, and protein levels of UCP1 were measured by western blotting. Representative gel images are shown. (C) Relative protein expression was normalized to β-actin levels. Values are mean ±SEM (n = 4).
