    摘要: A method for identifying compounds that inhibit amyloid-beta precursor protein processing in cells, comprising contacting a test compound with a SPHK polypeptide, or fragment thereof, and measuring a compound-SPHK property related to the production of amyloid-beta peptide. Cellular assays of the method measure indicators including phosphorylated kinase substrate and/or amyloid beta peptide levels. Therapeutic methods, and pharmaceutical compositions including effective amyloid-beta precursor processing-inhibiting amounts of SPHK expression inhibitors, are useful for treating conditions involving cognitive impairment such as Alzheimer's Disease.
