Whatever the mechanism of uptake, it is interesting to note that the signaling pathways evoked by the accumulation of intracellular Abeta resemble those evoked by extracellularly applied Abeta: transgenic rats overexpressing Abeta intraneuronally display elevated levels of phosphorylated ERK2 (Echeverria et al., 2004), as do rat hippocampal slices in response to bath-applied Abeta (Dineley et al., 2001). Again, bath-applied Abeta causes an increase in BAX and a decrease in BCL2 expression in neurons or neuronlike cell lines (Koriyama et al., 2003; Clementi et al., 2006). PubMed:19293145

AKT interacts with BAD to regulate apoptosis and, interestingly, also has many interacting partners in the insulin signaling pathway. Abeta increased activity of BAD, lowered the activity of the antiapoptotic protein BCL2, in rat hippocampal neurons in primary culture (Koriyama et al., 2003) and has been shown to be toxic to human neuroblastoma cells by increasing BAX activity and decreasing BCl-2 activity (Clementi et al., 2006).

The AD therapeutic AChE inhibitors donepezil, galantamine, and tacrine increase BCL2 expression when applied to cultured neuronal cells (Arias et al., 2004; Takada-Takatori et al., 2006). In these cells, nicotine promotes cell survival and causes the phosphorylation of the proapoptotic protein Bcl2-associated X protein (BAX), through the PI3K/AKT pathway, reducing the movement of BAX from the cytosol to the mitochondria and inhibiting its apoptotic activity (Xin and Deng, 2005).

In Alzheimer disease, 66 genes were identified that are also modulated by Protandim at the gene expression level. Of these 66 genes, the first 43 of them (65%) were regulated by Protandim in the opposing direction to that taken by the Alzheimer disease process. The beneficial effect of Protandim is further supported by the fact that of the 10 gene products currently targeted by drug therapies, eight of them are modulated by Protandim in the same direction that is proposed to be beneficial and caused by the drug.

Mechanistically, the Aβ induced neuronal apoptosis has been attributed to the increase in the ratio of proapoptotic gene (BAX) transcription to that of the anti-apoptotic gene Bcl-Xl, and/or to the reduction in constitutively activated NF-κB with consequent increase in the cytoplasmic IκB proteins PubMed:25652642
