LGALS4 and Alzheimer disease: Similar to Oregon-R control also elav-GAL4 and UAS-Aβ42/+ flies were less active than AD flies (elav-GAL4: −43.6%, ***p < 0.001; UAS-Aβ42/+: −46.4, ***p < 0.001) in the first half of the experiment (day 1–12) and showed more activity monitor counts (elav-GAL4: +22.3%, p > 0.05); UAS-Aβ42/+: +38.6%, **p < 0.01) from day 13–20 (Figures 5B,C).
