(A) l(2) mbn cells were labeled with the ATPsyn-α, and mitochondrial morphology was scored as fragmented, normal, or elongated. (B) Cells were treated with control or Dcp-1 dsRNA and subjected to nutrient-rich media or 1 h of starvation. Quantifications represent the percentage of cells with elongated mitochondria divided by the total number of cells examined. At least 100 cells were examined manually in three independent experiments (n = 3). Error bars represent the mean ± SD. Statistical significance was determined using one-way ANOVA with a Bonferroni post test (*, P < 0.05; **, P < 0.01).
