The inhibition by citrinin (CTN) of lipid peroxidation of mitochondria, sub-mitochondrial particles (SMP) and microsomes was studied. This effect was reversed by the presence of high concentrations of Fe3+ (0·4 and 0·5 mM), suggesting chelation of

The effects of citrinin in the maintenance of the homeostasis of the reactive oxygen species in rat liver cells were evaluated. Citrinin (CTN) modifies the antioxidant enzymatic defences of cells through the inhibition of GSSG-reductase and transhydr

The effects of amiodarone (AMD) on lipid peroxidation of rat liver mitochondria, the formation of superoxide anions at the respiratory chain level, and the cytosolic and mitochondrial enzymatic protective mechanisms of oxidative stress were studied.

The effects of citrinin on energy production along the respiratory chain and on glycolytic lactate production were examined in BHK-21 cultured cells. Citrinin inhibited the oxygen consumption rate by about 45 per cent. The respiratory rate of digiton

The effect of citrinin on Ca2+ transport was studied in isolated kidney cortex and liver mitochondria, and baby hamster kidney cultured cells. The mycotoxin significantly inhibited the activity of 2-oxoglutarate and pyruvate dehydrogenases in both ki

Citrinin depresses the phosphorylation efficiency of rat renal cortical mitochondria, as inferred from the decrease of the respiratory control coefficient (RC) and ADP/O ratios. The transmembrane potential (delta psi) developed by energized mitochond

The effects of the mycotoxin citrinin on renal cortical and liver mitochondrial swelling were studied. Citrinin decreases the rate of swelling induced by the valinomycin-K+ complex, suggesting that the mycotoxin interferes with the mitochondrial memb

Enalapril maleate (EM) is the salt of N-[(S)-1-ethoxycarbonyl)-3-phenylpropyl]-L-alanyl-L-proline, used therapeutically as an anti-hypertensive agent. The effects of EM on some aspects of the energy metabolism and membrane properties of mitochondria

The mycotoxin citrinin, depressed the phosphorylation efficiency of liver mitochondria as deduced from a decrease of respiratory coefficient and of the ADP/O ratio. Citrinin (1.0 mM) inhibited some enzymes linked to the respiratory chain, namely NADH

The effect of methotrexate (MTX) on transplasma-membrane electron transport and ferricyanide-induced proton extrusion by HeLa cells was studied. Both systems were inhibited by MTX. It is suggested that inhibition of electron transport and proton extr
