Polymerase Gamma Mutator (PolG) Mice Rely on Increased Glycolytic Flux for Energy Production

PolG mice have reduced mitochondrial oxidative capacity secondary to systemic mitochondrial dysfunction, and subsequently show exercise intolerance. While the deleterious effects on oxidative capacity in the PolG mice have been clearly documented, assessment of a compensatory increase in anaerobic capacity in PolG mice is lacking. Thus, we sought to delineate the extent of glycolysis/gluconeogensis as a means of energy production in the PolG …
