Specifically, Posiphen lowered sAPPa and sAPPb levels by 59.9% and 57.7%, respectively, assessed by the AlpaLisa assay, and by 34.1% and 34%, respectively, assessed by the MSD assay, in accordance with Posiphen’s proposed mechanism of action to inhibit APP expression. PubMed:22791904
We then tested the impact of anatabine on sAPPα and sAPPβ production using 7W CHO cells and observed that anatabine inhibits sAPPβ secretion without impacting sAPPα suggesting that anatabine is preventing the β-cleavage of APP (Fig. 4). PubMed:21958873
Nicotine does not appear to affect sAPPβ and sAPPα secretion in 7W CHO contrary to anatabine (Fig. 4) PubMed:21958873
We found that, like (-)-nilvadipine, Syk inhibition with the selective Syk inhibitor BAY61-3606 resulted in decreased sAPPβ secretion, BACE-1 mRNA, and BACE-1 protein expression (data not shown). PubMed:25331948
We have previously shown that racemic nilvadipine affects the β-cleavage of APP and reduces sAPPβ secretion PubMed:25331948

Dystrophic neurites are characterized by an accumula- tion of BACE-1 and sAPP β [31] and our previous work [28] has shown that Syk regulates BACE-1 expression and sAPP β levels suggesting that Syk upregulation in dystrophic neurites could contribute to the accumulation of BACE-1 and sAPP β .

Under physiological conditions activation of NF-κB by endogenous Aβ reduces βAPP, BACE1 and the γ-secretase activity, thereby lowering Aβ processing and facilitating Aβ homeostasis PubMed:25652642
However in AD, exposure to high Aβ concentrations upregulates NF-κB activation increasing βAPP and Aβ processing, precipitating a feed-back loop that favor exacerbated Aβ production PubMed:25652642
