Extension of Drosophila lifespan by Korean red ginseng through a mechanism dependent on dSir2 and insulin/IGF-1 signaling
Figure 2. Effect of KRG on stress resistance in fruit flies. Survival of fruit flies fed a KRG-containing diet or a control diet under heat-shock stress (A), starvation stress (C), and oxidative stress (E). (B) Recovery time of flies fed a KRG-containing diet or a control diet after cold-shock (freezing). (D) TAG level of flies fed a KRG-containing diet or a control diet. (F) The mRNA levels of antioxidant enzymes were analyzed in fruit flies fed a KRG-containing diet or a control diet for 7 or 40 days. Enzyme activity of SOD (G) or Cat (H) was measured after KRG or positive control paraquat treatment. *p < 0.05.
