cellular
• increase in intracellular calcium concentration and presence of hyperfused mitochondria in MEFs
• increase in mitochondrial mass in MEFs
• increase in the extra-cellular acidification rate and lactate production in MEFs
• expression analysis indicates increased autophagy in MEFs and in the liver
• selective impairment of proliferation of MEFs by glucose starvation
• glucose uptake is increased by 50% in MEFs compared to wild-type cells
• enhanced glycolysis and an decrease in ATP content in MEFs
• increase in O2 consumption rates and fatty acid oxidation in MEFs
• hyperpolarization of mitochondrial membranes in MEFs
• MEFs produce more glutathione indicating an increase in reactive oxygen species production
• increase in lipid peroxidation in MEFs and mice
• livers show increased 4-Hydroxy-2-nonenal staining and glutathione levels are increased in the blood indicating increased oxidative stress

homeostasis/metabolism
• expression analysis indicates increased autophagy in MEFs and in the liver
• glutathione levels and malonaldehyde content are increased in the blood

liver/biliary system
• livers show increased 4-Hydroxy-2-nonenal staining indicating increased oxidative stress
• increased autophagy and mitophagy in the liver
