PRC2 mutations suppress accumulation of pathogenic polyglutamine protein. a Animals expressing SCA3trQ78 in the photoreceptor cells have prominent nuclear inclusions. 3d animals, antibody to HA tag present on the SCA3trQ78 transgene (green). Dapi (blue), nuclei. Genotype: rh1-GAL4, UAS-SCA3trQ78/+. Scale bar indicates 10 μm. b Decreasing Pcl activity decreased SCA3trQ78 inclusions of 3d animals. Genotype: Pcl5/+; rh1-GAL4, UAS-SCA3trQ78/+. c Decreasing Su(z)12 activity decreased SCA3trQ78 inclusions of 3d animals. Genotype: rh1-GAL4, UAS-SCA3trQ78/Su(z)122. d Average number of inclusions detected in the region of interest in various genotypes. Mean ± SEM, n = 3 animals, using the average of at least 4 sections per animal. F2,6 = 27.84, p < 0.001, one-way ANOVA, with Tukey post-test **p < 0.01. e Mean size of inclusions. The size of inclusions detected in at least 4 sections per animal was determined, with the control cohort adjusted to 100%. The average size of inclusions was smaller in animals heterozygous for Pcl5 or Su(z)122. Mean ± SEM, n = 3 animals, using the average of at least 4 sections per animal. F2,6 = 30.89, p < 0.001, one-way ANOVA, with Tukey post-test, **p < 0.01
