Background: Glucocorticoids (GCs) modulate glucose homeostasis by acting on metabolic tissues including liver, adipose, and skeletal muscle. ABCC1 is a transmembrane ‘drug-resistance’ transporter expressed in adipose tissue and skeletal muscle with previously unknown physiological function. We recently showed that ABCC1 modulates intracellular GC concentrations and action in adipose. Here, we tested the hypothesis that Abcc1 regulates GC concentrations in skeletal mu...
