(A–F) images show the abnormal wing posture (B) and thoracic indentation (E) in the mutant compared to wild-type siblings (A,D). Quantification of %mutant individuals with abnormal wing posture (C) and thoracic indentation (F) showed a significant difference between vehicle- and drug (olmesartan)-treated samples. (G–J) Effect of olmesartan on the mitochondrial aggregation and DA neuron loss phenotypes of pink1 mutant, in comparison to DMSO control. Mitochondria are labeled with mito-GFP reporter. Data quantification shown in I, J. (n = 12; **, p < 0.01, *** p < 0.001, unpaired t-test).
