The levels of Aβ 40 and 42 were measured 48 hours post transfection.

** p < 0.05 as compared to PS1 wt transfected cells N = 3

* p < 0.01 as compared to PS1 wt transfected cells

Note: Due to the variation of absolute Aβ numbers in different experiments, only the comparative result to the cells transfected with pcDNA was used for comparison.
