The present invention discloses nucleic acid molecules encoding AD4 gene products, expression vectors and host cells suitable for expressing such gene products. Also disclosed are methods for treating, preventing, and diagnosing Alzheimers Disease.
Genetic Alterations Related To Familial Alzheimer's Disease
Isolated nucleic acid molecules are provided encoding human PS1 gene products. Mutant PS1 polypeptides are also provided, as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of the activity of the PS1 polypeptide and mutants thereof. Also provided are diagnostic methods for detecting Alzheimer's disease and therapeutic methods for treating the same.

Reduction Of Beta-Amyloid Levels By Treatment With The Small Molecule Differentiation-Inducing Factor
The present invention relates to novel uses for a family of small molecules, Differentiation-Inducing Factors (DIFs). It has been discovered that DIFs surprisingly can alter the metabolic processing of amyloid precursor protein (APP) and in turn reduce the level of secreted Aβ. The metabolic processing of other γ-secretase substrates normally present in cells (Notch and APLP1) is not affected when treated with DIF. The invention provides methods for reducing Aβ production in mammalian cells that express APP by administering DIF-I, DIF-2, DIF-3, a functionally equivalent analog and or any combination thereof. The invention also provides methods for treating and/or preventing Alzheimer's disease by preferentially reducing Aβ production.

International Classification:
A61K 3800
US Classification:
530300
Abstract:
The present invention is directed to isolated amyloid precursor-like proteins (APLPs), nucleotide sequences coding for and regulating expression of these protein, antibodies directed against these proteins, and recombinant vectors and host cells containing the genetic sequences coding for and regulating the expression of these protein sequences. The invention is also directed to isolated genomic. DNA, cDNA anti-sense RNA, and RNA containing the protein sequence. Antibodies can be used to detect an APLP in biological specimens, including, for example, fluid, serum or tissue samples. APLP1 and APLP2 are candidate genes for late onset familial Alzheimer's disease.
