Modulation of pyruvate dehydrogenase kinase activity in cultured hepatocytes by glucagon and n-octanoate
The Biochemical Journal
|February 15, 1986
Abstract:
The activity of pyruvate dehydrogenase kinase in extracts of mitochondria from rat hepatocytes cultured for 21 h in medium 199 was increased 2.5-fold by the presence of 55 nM-glucagon and 1 mM-sodium n-octanoate in the culture medium. The change was comparable with that induced in vivo by 48 h starvation. The potential contribution of branched-chain complex to estimates of PDH-complex activity in rat liver mitochondria has been defined.
