Measurements of protein levels in white and brown adipose tissue. WAT protein levels of IL-6 and IL-1β in DIO animals (a) and in ob/ob mice (b). BAT protein levels of PGC1-α in ob/ob mice (c). β-actin for WAT and α-tubulin for BAT were used to normalize protein levels. Values are mean ± SEM of 7-8 animals per group. ; ; versus controls.
