Mitochondrial adaptation in steatotic mice.
Mitochondrion, DOI: 10.1016/j.mito.2017.08.015 (2018)
Western lifestyle-associated malnutrition causes steatosis that may progress to liver inflammation and mitochondrial dysfunction has been suggested as a key factor in promoting this disease. Here we have molecularly, biochemically and biophysically analyzed mitochondria from steatotic wild type and immune-compromised mice fed a Western diet (WD) - enriched in saturated fatty acids (SFAs). WD-mitochondria demonstrated lipidomic changes, a decreased mitochondrial ATP production capacity and a significant sensitivity to calcium. These changes preceded hepatocyte damage and were not associated with enhanced ROS production. Thus, WD-mitochondria do not promote steatohepatitis per se, but demonstrate bioenergetic deficits and increased sensitivity to stress signals.
