Fig. 4From: Longevity in the red flour beetle Tribolium castaneum is enhanced by broccoli and depends on nrf-2, jnk-1 and foxo-1 homologous genesThe effect of selected isothiocyanates on the survival of T. castaneum at 42 °C, based on their concentration in a normal diet supplemented with 5 % lyophilized broccoli. The concentrations were set to 0.01 % sulforaphane (a), 0.001 % phenylethylisothiocyanate (b) and 0.001 % allylisothiocyanate (c). **p < 0.01Back to article page
