(a) Hippocampal neurons were transfected with WT APP695, BACE1-GFP and
the indicated shRNA constructs. 72 hours after transfection, internalized APP
(60 min) was immunostained (red) to visualize colocalization of internalized APP
and BACE1 in axons. Scale bar: 10 μm.
(b) Quantification of colocalization of internalized APP with BACE1 in
axons. N (cells) = 8 (Luciferase shRNA), 13 (Par3 shRNA), from 3 independent
experiments. Data were expressed as Mean ± SEM with Student’s t
test: **p<0.01.
