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). PubMed:19293145

a(CHEBI:nicotine) decreases bp(GO:"apoptotic process") View Subject | View Object

Nicotine protects PC12 cells from cell death resulting from serum depletion through a mechanism that depends upon the function of IP3 receptors, L-type calcium channels, ryanodine receptors, and ERK, suggesting that the protective effect of nicotine is mediated by calcium signaling pathways (Ren et al., 2005).

Furthermore, nicotinic activation of ERK-1/2 promotes survival of cultured murine spinal cord neurons, and the blocking of ERK-1 prevents nicotine’s antiapoptotic action (Toborek et al., 2007). Likewise, the alpha7-specific agonist A-582941 induces phosphorylation of ERK-1/2 in PC12 cells and in mouse brain, and this is completely blocked by the mitogen-activated protein kinase 1 inhibitor SL327 (Bitner et al., 2007).

p(HGNC:FYN) decreases bp(GO:"apoptotic process") View Subject | View Object

In a microarray study comparing brains from patients with AD with control brains, FYN was found to be significantly upregulated in AD (Wang et al., 2003a). In this context, it is of interest that FYN has also been shown to activate the PI3K/AKT cascade, thereby inhibiting apoptosis (Tang et al., 2007). Indeed, FYN is required for phos- phorylation of phosphoinositide 3-kinase enhancer (PIKE), which itself regulates AKT (Fig. 3). PIKE binds to AKT and up-regulates its kinase a ctivity, thereby reducing apoptosis. Phosphorylation protects PIKE from caspase cleavage, hence FYN is antiapoptotic (Tang et al., 2007).

complex(p(FPLX:AKT), p(HGNC:BAD)) regulates bp(GO:"apoptotic process") View Subject | View Object

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). PubMed:19293145

act(p(HGNC:MAPK1)) increases bp(GO:"apoptotic process") View Subject | View Object

Abeta initiates intracellular signaling cascades via nAChRs (Fig. 3), including the MAPK kinase signaling pathway, resulting in cell death. In hippocampal slices, Abeta activates ERK-2 isoforms of the ERK MAPK. This is blocked by alpha7 antagonists, suggesting that Abeta evokes the cascade through alpha7 nAChRs (Dineley et al., 2001). PubMed:19293145

act(p(FPLX:PI3K)) decreases bp(GO:"apoptotic process") View Subject | View Object

For instance, over-expressing PI3K in Drosophila melanogaster neurons in situ results in an increase in functional synapses as well as synaptic sprouting (Martín-Pen˜ a et al., 2006). Thus it is possible that nicotine’s activation of the PI3K pathway results in increased synaptic stability, and it would be of interest to explore this further in vertebrates. Thus, the evidence suggests that activation of nAChRs activates the PI3K/AKT pathway to favor antiapoptotic pathways and possibly induce synaptogenesis. PubMed:19293145

act(p(HGNC:MYC)) increases bp(GO:"apoptotic process") View Subject | View Object

Application of nicotine to rat microglia results in the up-regulated expression of cyclooxygenase-2 and prostaglandin E2 (De Simone et al., 2005). Signaling pathways downstream to the MAPK pathway are similarly well placed to effect changes in gene expression. For example, alpha7-dependent activation of the MAPK pathway is known to activate c-Myc (Liu et al., 2007), a protooncogene whose transcription product sensitizes cells to pro-apoptotic stimuli.

A recent study showed that thrombin is elevated in microvessels isolated from AD brain compared to microvessels from control brain (33). Additionally, thrombin was present in the CSF of AD patients but not in that of controls (33). This is important, as thrombin can act as a neurotoxin by activating intracellular signaling cascades causing neurite retraction and stimulating apoptosis (34–36) PubMed:24027553

Thrombin may also be influencing tau pathology, as treatment of immortalized hippocampal neuronal cells (HT22 cells) with thrombin resulted in the formation of thioflavin-S positive tau aggregates within 24 h, followed by an increase in cell death at 72 h (37). PubMed:24027553

p(HBP:"Tau C3") increases bp(GO:"apoptotic process") View Subject | View Object

There may be reciprocity with the apoptosis pathway as activating caspase-3 by inducing apoptosis in cortical neuronal culture led to tau cleavage (22), and selectively expressing tauC3 led to apoptosis in NT2 and COS cells (21).

Caspase-6 was also shown to cleave the N-terminus of tau in vitro (24). Caspase-3, which is a key effector in the apoptotic cascade, cleaves tau predominantly at the C-terminal D421 site generating a fragment often referred to as tauC3 (22, 23). PubMed:24027553

In this report, we describe a novel mechanism of action determined by the JunD component of AP-1, a factor enhancing cell survival in v-Src-transformed cells. We show that the loss of JunD results in the aberrant activation of a genetic program leading to cell death. This program requires the activation of the tumor suppressor death-associated protein kinase 1 (DAPK1). Since DAPK1 is phosphorylated and inhibited by v-Src, these results highlight the importance of this kinase and the multiple mechanisms controlled by v-Src to antagonize the tumor suppressor function of DAPK1.

We show here that ITPKB protein level was increased 3-fold in the cerebral cortex of most patients with Alzheimer's disease compared with control subjects, and accumulated in dystrophic neurites associated to amyloid plaques. In mouse Neuro-2a neuroblastoma cells, Itpkb overexpression was associated with increased cell apoptosis and increased β-secretase 1 activity leading to overproduction of amyloid-β peptides. In this cellular model, an inhibitor of mitogen-activated kinase kinases 1/2 completely prevented overproduction of amyloid-β peptides. Transgenic overexpression of ITPKB in mouse forebrain neurons was not sufficient to induce amyloid plaque formation or tau hyperphosphorylation. However, in the 5X familial Alzheimer's disease mouse model, neuronal ITPKB overexpression significantly increased extracellular signal-regulated kinases 1/2 activation and β-secretase 1 activity, resulting in exacerbated Alzheimer's disease pathology as shown by increased astrogliosis, amyloid-β40 peptide production and tau hyperphosphorylation.

The three sensors of ER proteotoxic stress facilitate contra- dictory responses since they either promote cell survival by decreasing the misfolded protein and/or oxidative load, or, if UPR fails, they promote the activation of apoptotic pathways that eventually result in cell death [57].

To address this question, we first applied the oligomers directly after the purification of the protein eluting from the Butyl FF 16/ 10 column (without buffer exchange; 1, 5, and 10 mM) to SHSY5Y cells and observed a variety of toxic effects, including pronounced reduction in the cell viability (by MTT assay, Fig. 3A), increase in apoptotic cells (by Hoechst staining, Supplementary Fig. 4A), loss of mitochondrial membrane potential (by JC1 assay, Supplementary Fig. 4B), caspase 3/7 activation (Supplementary Fig. 4C-D), and cytochrome-c release (Supplementary Fig. 4), within 5 hours of incubation.

There may be reciprocity with the apoptosis pathway as activating caspase-3 by inducing apoptosis in cortical neuronal culture led to tau cleavage (22), and selectively expressing tauC3 led to apoptosis in NT2 and COS cells (21). This might represent a feed-forward loop of neurotoxicity. PubMed:24027553

A relationship has recently been reported between the expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and apoptotic events14. Real-time RT-PCR experiments showed that the expression of GAPDH was significantly increased by the addition of GA (Fig. 2a). These results suggested that GA caused cell toxicity concomitant with increases in the gene expression of GAPDH in SH-SY5Y cells. PubMed:26304819
