Research Abstract

加齢による学習記憶力の低下(加齢性記憶障害)は脳老化の重要な表現型である。我々は世界で初めてとなる加齢性記憶障害の特異的な抑制変異体DC0/+を単離し、PKA活性が加齢性記憶障害を発生させることを明らかにした。本研究では加齢性記憶障害と相関するタンパクの動態をプロテオミクス解析により調べた。その結果、Pyruvate Carboxylase (PCx)に高いホモロージーを持つCG1516によりコードされるタンパクの発現動態とリン酸化動態に加齢性記憶障害との高い相関を見出した。CG1516の機能欠失型変異体を用いて加齢性記憶障害を調べたところ、顕著な加齢性記憶障害の抑制がみられた。さらにPKAの過剰発現による加齢性記憶障害様の記憶障害が、CG1516の機能欠失型変異体ではみられなかった。以上の結果から、加齢に伴うPKA依存性のPCxの活性上昇が加齢性記憶障害の原因であることが示唆された。
