We used GS-Gal4>Aβ42>+ −RU flies (Figure 4A), which did not induce Aβ42 expression, as the negative control, and used GS-Gal4>Aβ42>+ +RU flies (Figure 4B), the Drosophila AD model, which induces ubiquitous Aβ42 expression, as the control. This evidence concerns the gene LGALS4 and Alzheimer disease.
