| Outline of Final Research Achievements |
We previously found that a production ratio of Aβ42/Aβ40 was decreases in a differentiation day-dependent manner when we differentiated human iPS cells to neuronal cells, suggesting that a γ-secretase-modulating factor may be expressed in the cells, because gene expression of any component of the γ-secretase complex was not changed. So, we analyzed a neuronal differentiation day-dependent gene expression profile and selected some genes as a tentative candidate gene of γ-secretase-modulating factor. We cloned the tentative candidate genes, transfected them into neuronal cells, and measured a production ratio of Aβ42/Aβ40 in cultured medium. To date, we identified one of zinc transporter as γ-secretase-modulating factor. Now, we are planning to confirm this function of the zinc transporter using some different experimental paradigms.
