What the literature leaves open

  • Finally, GSR activity was measured as a functional readout of NADPH-dependent antioxidant capacity, whereas other NADPH-dependent systems, such as thioredoxin reductase, remain to be examined in future studies. L-malate-specific respiration was not directly assessed in permeabilized hepatocytes or isolated mitochondria, which remains a limitation of the present study.

  • Several limitations of the present study should be acknowledged.
