Effects of AMFR on APP amyloidogenic cleavage products. A AMFR and APP protein levels in SH-SY5Y-hAPP cells transfected with empty vector or His-AMFR. Data are shown as mean ± SEM from three independent experiments (*P < 0.05, ****P < 0.0001). B-D sAPPβ, Aβ40, and Aβ42 levels in SH-SY5Y-hAPP cells transfected with empty vector or His-AMFR by ELISA assays. Data are shown as mean ± SEM from three independent experiments (*P < 0.05, ****P < 0.0001). E AMFR and APP protein levels in SH-SY5Y-hAPP cells transfected with siRNA-control or siRNA-AMFR. Data are shown as mean ± SEM from three independent experiments (*P < 0.05, ***P < 0.001). F–H sAPPβ, Aβ40, and Aβ42 levels in SH-SY5Y-hAPP cells transfected with siRNA-control or siRNA-AMFR by ELISA assays. Data are shown as mean ± SEM from three independent experiments (*P < 0.05). I AMFR and APP protein levels in primary neurons of APP/PS1 embryonic mice transfected with empty vector or His-AMFR. Data are shown as mean ± SEM from three independent experiments (*P < 0.05). J-L sAPPβ, Aβ40, and Aβ42 levels in primary neurons of APP/PS1 embryonic mice transfected with empty vector or His-AMFR by ELISA assays. Data are shown as mean ± SEM from three independent experiments (*P < 0.05)
