The expression of autophagy-related genes is upregulated in flies expressing expanded CUG or CCUG repeats in muscle or heart. Relative expression levels of Atg4, Atg7, Atg8a, Atg9 and Atg12 measured by qRT-PCR in muscle (Mhc-Gal4 driver; A) and heart samples (GMH5-Gal4 driver; B), showed a significant upregulation of these autophagy-related genes in flies expressing expanded CUG (CUG(250)×) or CCUG repeats (CCUG(1100)×). The histograms show the mean ± SEM. *p < 0.05, **p < 0.01, ***p < 0.001 (Student’s t-test).
