Gullapalli, S and Shivaswamy, V and Ramasarma, T and Kurup, CK (1989) Increase in alpha-glycerophosphate dehydrogenase and other oxidoreductase activities of hepatic mitochondria on administration of vanadate to the rat. In: Indian Journal of Biochemistry & Biophysics, 26 (4). pp. 227-233.Full text not available from this repository.
Liver mitochondria isolated from vanadate-administered rats showed increased (20-25%) rates of oxidation of both NAD(+)-linked substrates and succinate. Respiratory control index and ADP/O were unaffected by the treatment. Dormant and uncoupler-stimulated ATPase activity also was not affected by vanadate administration. Membrane-bound, electron-transport-linked dehydrogenase activities (both NAD(+)- and succinate-dependent) increased by 15-20% on vanadate treatment. Mitochondrial alpha-glycerophosphate dehydrogenase activity increased by 50% on vanadate administration. The above effects of vanadate on oxidoreductase activities could be prevented by the prior administration of antagonists to alpha-adrenergic receptors. Substrate-dependent H2O2 generation by mitochondria also showed an increase on vanadate administration.
