Top: Immunoblot assessing the effect of mtON activation on AMPK phosphorylation status. Top bands (~62 kDa) are phosphorylated AMPK signal, and bottom bands (~43 kDa) are actin signal. Image is from the same membrane cut to separately probe for phosphorylated AMPK (pAMPK) and actin. Bottom: Densitometry analysis showing decreased pAMPK to actin ratio, as there is no known antibody directed against total AMPK in C. elegans. Phosphorylation increases in the absence of food, but low phosphorylation is preserved when mtON is activated, two-way ANOVA with Sidak's test for multiple comparisons, *p = 0.0203, n = 3,3,3,4,4 biological replicates each bar from left to right. Data show mean + standard deviation.
