NAC treatment impairs physical performance and mitochondria function in atg7f/f mice. (A) Mean maximal running distance after 1 (left) and 3(right) d of eccentric exercise with and without NAC treatment in atg7f/f and atg7−/− females (NAC-treated n = 6 atg7f/f, n = 4 atg7−/−). NAC treatment did not improve atg7−/− but rather worsened atg7f/f physical performance. (B) TMRM analysis of atg7f/f females pre-exercise (top) and postexercise (bottom) after NAC treatment. Mitochondrial ability to maintain membrane potential is compromised by prolonged antioxidant treatment (n > 15 per condition).
