Molecular mechanism for Alzheimers disease: possible therapeutic targets Sungkwon Chung, Ph. D. Dept. of Physiology, Sungkyunkwan University, School of Medicine 13:30-14:30, April 4, Wednesday, 2012 Room 103, Building 1, DGIST Familial Alzheimers disease (FAD)-associated mutations in genes encoding presenilin 1 or 2 (PS1, PS2) lead to several cellular phenotypes, including alteration in -secretase-mediated cleavage of -amyloid precursor protein (APP) which liberates amyloid -peptide (A), leading to increase in amyloidogenic 42-residue A (A42) relative to A40. Independent of their role in -secretase function, presenilins are shown to modulate Ca2+ entry. We found that Ca2+ entry via the transient receptor potential melastatin 7 (TRPM7) channel was attenuated by the presence of FAD-associated PS1 mutants, such as E9 and L286V. Since our previous studies showed that the down-regulation of phosphatidylinositol-4,5-bisphosphate (PIP2) is attributable to the observed Ca2+ deficits, we attempted to test whether the intracellular delivery of PIP2 could restore theses phenotypes from FAD-associated PS mutants. Also, application of PIP2 reduced A42 levels but not A40 levels from PS mutant-transfected cells. Interestingly, A42 levels were not changed by PIP2 from PS wild-type cells, indicating that the effect of intracellular PIP2 is specific for PS mutant. Thus, the down-regulated PIP2 level may play an important role for regulating Ca2+ influx as well as the increased generation of A42 from FAD-associated PS mutants. Our results also indicate that regulating intracellular PIP2 level is a potential therapeutic target for AD. O-GlcNAcylation is a novel type of O-linked glycosylation attaching the monosaccharide N-acetylglucosamine (GlcNAc) to serine and threonine residues. In fact, APP was the first plasma membrane protein shown to be O-GlcNAcylated. Recently, it is shown that O-GlcNAcylation of APP increases the non-amyloidogenic processing of APP and decreases the production of A. Even though O-GlcNAcylation has been shown to modify the processing of APP, the role of O-GlcNAcylation in APP trafficking and endocytosis remains unknown. We found that when O-GlcNAcylated APP was increased, the level of APP in the plasma membrane was increased. Also, the level of sAPP (-secretase product) increased, while the level of sAPPb(b-secretase product) was concomitantly decreased, indicating the increased non-amyloidogenic processing of APP. Consistent with this results, the secreted levels of A species (A40 and A42) decreased. These results strongly indicate that O-GlcNAcylation increases the plasma membrane targeting of APP, where it can be cleaved preferentially by -secretase and g-secretase. The non-amyloidogenic processing of APP reduces the generation of A. Thus, O-GlcNAcylation of APP is implied as a potential therapeutic target for AD. ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Person in charge : Jeong Min Lee, Contact: yjm0329@dgist.ac.kr, 053)785-6101 Seminar Department of Brain Science
