TSG (2,3,5,4′-Tetrahydroxystilbene-2-O-β-D-glucoside) from the Chinese Herb Polygonum multiflorum Increases Life Span and Stress Resistance of Caenorhabditis elegans

Figure 4

Modulation of GST-4 expression by TSG. The images show GFP fluorescence of the head and the anterior part of the intestine of CL2166 transgenic nematodes pretreated with 100 μM of the compounds followed by an incubation under physiological conditions or under conditions of oxidative stress (150 μM Juglone; 3 h). Data represent mean values ± SEM, , versus corresponding DMSO value, one-way ANOVA with Dunnett’s post hoc test. At least 10 animals per group and experiment were analysed.
