Regulation of pyruvate dehydrogenase and pyruvate dehydrogenase phosphate phosphatase activity in rat epididymal fat-pads. Effects of starvation, alloxan-diabetes and high-fat diet.

چکیده
1. Pyruvate dehydrogenase phosphate phosphatase activity in rat epididymal fat-pads was measured by using pig heart pyruvate dehydrogenase [32P]phosphate. About 80% was found to be extramitochondrial and therefore probably not directly concerned with the regulation of pyruvate dehydrogenase activity. The extramitochondrial activity was sensitive to activation by Ca2+, but perhaps less sensitive than the mitochondrial activity.

Alterations in adipose-tissue pyruvate dehydrogenase activity in starved, fat-fed and diabetic rats.
The pyruvate dehydrogenase complex in mammalian tissues exists in a phosphorylated (inactive) and in a non-phosphorylated (active) form. These forms are interconverted by an ATP-requiring kinase, which is inhibited by pyruvate, ADP and thiamin pyrophosphate, and a phosphatase, which is activated both by Mg2+ and by Ca2+ ions (Linn et al., 1969; for recent review, see Denton et al., 1975). Brief...

1. The conversion of inactive (phosphorylated) pyruvate dehydrogenase complex into active (dephosphorylated) complex by pyruvate dehydrogenase phosphate phosphatase is inhibited in heart mitochondria prepared from alloxan-diabetic or 48 h-starved rats, in mitochondria prepared from acetate-perfused rat hearts and in mitochondria prepared from normal rat hearts incubated with respiratory substra...

1. Isolated rat epididymal fat-cell mitochondria showed an inverse relationship between ATP content and pyruvate dehydrogenase activity consistent with competitive inhibition of pyruvate dehydrogenase kinase by ADP. At constant ATP concentration pyruvate rapidly activated pyruvate dehydrogenase in fat-cell mitochondria, an observation consistent with inhibition of fat-cell pyruvate dehydrogenas...

The total activity of pyruvate dehydrogenase (PDH) complex in rat hind-limb muscle mitochondria was 76.4 units/g of mitochondrial protein. The proportion of complex in the active form was 34% (as isolated), 8-14% (incubation with respiratory substrates) and greater than 98% (incubation without respiratory substrates). Complex was also inactivated by ATP in the presence of oligomycin B and carbo...
متن کاملRegulation of Pyruvate Dehydrogenase in Rat Heart
1. The proportion of active (dephosphorylated) pyruvate dehydrogenase in perfused rat heart was decreased by alloxan-diabetes or by perfusion with media containing acetate, n-octanoate or palmitate. The total activity, of the dehydrogenase was unchanged. 2. Pyruvate (5 or 25mm) or dichloroacetate (1m) increased the proption of active (dephosphorylated) pyruvate debydrogenase in perfused rat hea...
