HCV causes hepatic steatosis and insulin resistance, while HBV confers increased risk of liver cancer. We hypothesized these differences may be due to virus-specific effects on mitochondrial function.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Seahorse technology was used to investigate effects of virus infection on mitochondrial function. Cell-based assays were used to measure mitochondrial membrane potential and quantify pyruvate and lactate. Mass spectrometry was performed on mitochondria isolated from HBV-expressing, HCV-infected, and control cells cultured with isotope-labelled amino acids, to identify proteins with different abundance. Altered expression of key mitochondrial proteins was confirmed by real-time polymerase chain reaction (PCR) and western blot.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Reduced mitochondrial function and ATP production were observed with HCV infection and HBV expression. HCV impaired glycolysis and fatty acid oxidation, promoting lipid accumulation whereas HBV caused lactate accumulation. In HBV-expressing cells enrichment of pyruvate dehydrogenase kinase inhibited pyruvate to acetyl-CoA conversion thereby reducing its availability for mitochondrial oxidative phosphorylation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>HBV and HCV impair mitochondrial function.
