KAT5 and Huntington disease: In contrast, Tip60 showed slight but non-significant reduction in the PD Drosophila brain (Fig. 2B: (t(4) = 2.468, p = 0.0691, unpaired t-test), significantly reduced in the ALS Drosophila brain (Fig. 2C: (t(4) = 4.589, p = 0.0101, unpaired t-test) and upregulated in the HD Drosophila brain (Fig. 2A:t(4) = 3.392, p = 0.0275, unpaired t-test).
