Glucose utilization in vivo and insulin-sensitivity of rat brown adipose tissue in various physiological and pathological conditions

Abstract

Brown-adipose-tissue glucose utilization rate and its insulin-sensitivity were measured in vivo in the anaesthetized rat by a 2-deoxy[1-3H]glucose technique. Glucose utilization can be increased 60-fold by insulin, to reach extremely high rates. Glucose utilization and its insulin-sensitivity are modulated in accordance with physiological or pathological conditions.
