[HTML][HTML] Dimethylbiguanide inhibits cell respiration via an indirect effect targeted on the respiratory chain complex I

MY El-Mir, V Nogueira, E Fontaine, N Avéret… - Journal of Biological …, 2000 - ASBMB
We report here a new mitochondrial regulation occurring only in intact cells. We have
investigated the effects of dimethylbiguanide on isolated rat hepatocytes, permeabilized
hepatocytes, and isolated liver mitochondria. Addition of dimethylbiguanide decreased
oxygen consumption and mitochondrial membrane potential only in intact cells but not in
permeabilized hepatocytes or isolated mitochondria. Permeabilized hepatocytes after
dimethylbiguanide exposure and mitochondria isolated from dimethylbiguanide pretreated …
