Guanosine protects SH-SY5Y cells against β-amyloid-induced apoptosis

1 Apr 2004

Abstract excerpt

Apoptosis is implicated in the pathophysiology of Alzheimer's disease. Extracellular guanosine inhibits staurosporine-induced apoptosis in astrocytes. We examined whether guanosine protects SH-SY5Y human neuroblastoma cells against beta-amyloid(betaA)-induced apoptosis. Addition of betaA (fragment 25-35, 5 microM for 24 h) to SH-SY5Y cells increased the number of apoptotic cells, as evaluated by oligonucleosome...
