Research Abstract

Neurofibrillary tangles (NFTs) are neuropathological hallmarks of Alzheimer disease (AD) and abnormally hyperphosphorylated tau is the major protein component of NFTs. According to our previous studies on the regulation of phosphorylation of tau protein, an involvement of intrinsic anti-apoptotic factor in neurodegenerative process in AD, is speculated. Therefore XIAP (X chromosome-linked inhibitor of apoptosis), one of intrinsic anti-apoptotic proteins, was investigated in this study. First, transfected XIAP protected COS cells from death and increased phosphorylation of tau protein in cells treated with 1 μM of wortmannin, an inhibitor to phosphatidylinositol 3-kinase. Second, the binding of XIAP with N-terminal tau sequence was observed only when the first methionine was deleted. These results suggest that XIAP might be involved in neurodegenerative process of AD or tauopathy, that is slowly progressive.
