Research Abstract

ゲノム刷り込みは哺乳動物のみに見られる、世代を超えた現象であるため、すべての実験は酵母人工染色体導入マウス(YAC TgM)を用いて行う。
(1)YAC TgMの初期胚を用いて、受精後メチル化刷り込みの確立時期を決定する(H20)
(2)受精後メチル化刷り込み確立におけるインシュレータータンパク質・CTCFの必要性を検証するためにYAC TgMを作製・解析する(H20)
(3)受精後メチル化刷り込み確立における、特定のcis制御配列の関与を検証するためにYAC TgMを作製・解析する(H21以降)
(4)受精後メチル化刷り込み確立に必要十分な要素を決定するためにYAC TgMを用いた再構築実験を行う(H21以降)
(5)受精後メチル化刷り込み確立に必要な最小領域を決定するために、欠失変異体を用いてYAC TgMを作製・解析する(H21以降)
(6)YAC TgMを用いた母親由来メチル化刷り込み再現の検討を行う(H21以降)
