Abundance of rRNA, normally and in T2D. RNA was isolated from human adipocytes obtained from five non-diabetic control subjects (blue) (mean age, 62 years (range, 57–69); mean BMI, 23 kg/m2 (range, 22–24)) and five subjects with type 2 diabetes (red) (mean age, 68 years (range, 45–79); mean BMI, 34 kg/m2 (range, 28–43)). RNA samples were then analyzed for the abundance of 18S rRNA by real time PCR. Data are presented as fraction of the mean of non-diabetic controls, mean ± S.E. (error bars), of cell preparations from the indicated number of subjects.
