A four‐ to fivefold overexpression of the gene for the Alzheimer β/A4 amyloid precursor protein (APP) in individuals with Down's Syndrome (DS) appears to be responsible for the fifty year earlier onset of Alzheimer's disease (AD) pathology in DS compared to the normal population. It is therefore likely that a deregulated overexpression of the APP gene is a risk factor for the β/A4 amyloid formation. To test this hypothesis and to get a better understanding of how APP expression is regulated, we…

Mechanism for β-amyloid Overproduction in Alzheimer Disease
A mechanism is proposed that may be responsible for the overproduction of Aβ in sporadic AD, which constitutes the majority of all AD cases and makes several verifiable predictions and suggests new directions of experimentation that may lead to a better understanding of the mechanisms involved in AD.
Alzheimer’s disease: towards therapeutic manipulation of the amyloid precursor protein and amyloid β-peptides
• Biology
• 1997
This review will cover patenting activity concerning APP and Aβ for the period 1995 - 1996 and special emphasis is placed on the patent applications aimed at preventing Aβ aggregation since this seems to be a key event in potentiating Aβ neurotoxicity.
Physiological role of amyloid precursor protein during neural development
The physiological functions of the zebrafish Appb, a highly conserved homologue of human APP, during neural development are examined and it is found that Appb is required for the patterning and outgrowth of motor neurons in the spinal cord as well as for the synapse formation at the neuromuscular junctions, thus essential for the formation of normal locomotor behavior.
β-Amyloid precursor protein transgenic mice that harbor diffuse Aβ deposits but do not form plaques show increased ischemic vulnerability: Role of inflammation

Findings elucidate molecular mechanisms of neuronal injury in AD and suggest that antiinflammatory compounds preventing activation of p38 MAPK in microglia may reduce neuronal vulnerability in AD.
DNA Methylation and Alzheimer’s Disease
It is of interest to note that it has been shown that AD patients tend to have low levels of folate and high levels of homocysteine, and parental influences in the inheritance of AD have been demonstrated, likely caused by gene imprinting.
The role and therapeutic targeting of α-, β- and γ-secretase in Alzheimer's disease
• Biology

• 2015
Research efforts that have attempted to inhibit the generation of the Aβ peptide through modulation of the activity of the proteolytic secretases that act on APP are reviewed and whether this is a viable therapeutic strategy for treating AD is discussed.
Upregulation of SET Expression by BACE1 and its Implications in Down Syndrome

This work provides a new insight that BACE1 overexpression not only promotes neuritic plaque formation but may also potentiate neurodegeneration mediated by SET elevation in Alzheimer-associated dementia in DS.

Evidence is presented that the transcription factor Sp1 can bind to element A and that another specific complex, called C2A, can be observed, which covers a region overlapping with the Sp1 binding site on the APP promoter.
