Mitochondrial function, ROS and ETC complex protein expression levels in quadricep muscle. (a) Quadriceps muscle mitochondrial membrane potential (ΔΨm), (b) mitochondrial reactive oxygen species (mtROS) levels, (c) total cellular ROS levels and (d) superoxide dismutase 2 (SOD2) levels in healthy never-smokers, ex-smokers, GOLD Grade 2 and GOLD Grade 3/4 patients. Data shown as mean ± SEM; never-smokers (n = 5), ex-smokers (n = 8), GOLD Grade 2 patients (n = 6), and GOLD Grade 3/4 patients (n = 6); *p < 0.05, **p < 0.01, Mann-Whitney test
