FIGURE 7:
PI3K activation increases Aβ42 protein deposits without affecting transcription. (A–D) Representative confocal images of 15-d-old adult heads stained with 6E10 antibody of the indicated genotypes. Note the large increase of amyloid deposits (white) revealed by the 6E10 antibody. Cell nuclei are marked by DAPI (magenta). (E) Western blot of adult heads of the same genotypes and age. Data correspond to three independent Western blots normalized for tubulin content as internal control. Note the significant increase of the 6E10 signal elicited by PI3K activation. One-way ANOVA significance is indicated with **, p < 0.01. (F) RT-qPCR data from the same genotypes and ages. Data represent mean ± SD. Statistical significance was analyzed by Student’s t test. Scale bar is 50 µm.
