Figure 1. TRAP1 regulates ROS levels in vivo.
(A–C) Optic lobes of young adult Drosophila brains stained with Mitosox, and (D–F) larval segmental nerves of corresponding genotypes stained with antibody against mitochondrial Complex V. (A and D)w1118; +/+; +/+(B and E)w; TRAPΔ4/TRAPΔ4; +/+, (C and F) w; +/+; UAS-TRAP17M/ActinGal4. (G) MitoSox staining is significantly increased in w; TRAPΔ4/TRAPΔ4; +/+ mutants. While staining is marginally reduced in overexpression flies w; +/+; UAS-TRAP17M/ActinGal4, it is not significantly different from wildtype. Error bars denote standard deviation of means. N = 3–5. (**) indicate p < 0.001 from Student’s t-test. Mitochondrial distribution appears normal in mutant and overexpression animals in segmental nerves of Drosophila larvae. In all cases, scale bars equal 10 µm.
