"Both AZD2281 and NR induced a strong superoxide burst at day 1 of adulthood, although at this stage no protective activation of
sod-3 expression was observed (Figure 3C). When we measured at the same age UPRmt activation using
hsp-6::GFP reporter worms (Yoneda et al., 2004), both compounds robustly induced UPRmt (Figure 3D), without activating the ER-specific unfolded protein response (
hsp-4::GFP; Figure 3E)."
