From: Lung glutathione adaptive responses to cigarette smoke exposure
GSH synthesis increases during the CS exposure recovery periods in both the lung and liver. γ-Glutamylcysteine ligase (GCL) is the rating limiting step in GSH synthesis and it was measured in the lung (A) and liver (B) at multiple time points during the CS exposure and during the recovery period. Data represented as mean ± SEM, with different letters representing statistically significant differences between groups, p < 0.05.
