2015 Fiscal Year Research-status Report

新規alpha-synuclein発現調節modifier遺伝子の同定と機能解明

Research Project

Project/Area Number 25860726
Research InstitutionJuntendo University

Principal Investigator

西岡 健弥  順天堂大学, 医学部, 准教授 (40348933)

Project Period (FY) 2013-04-01 – 2017-03-31
Keywordsパーキンソン病 / 遺伝子 / Gene chip
Outline of Annual Research Achievements

遺伝性パーキンソン病(PD)原因遺伝子産物alpha-synucleinは孤発性PDやレビー小体型認知症の病理学的特徴であるレビー小体を構成し病態に深く関与するとされる。本研究ではalpha-synclein 遺伝子2倍体/3倍体変異により発症する家族性PD(PARK1)臨床像の多様性に着目し、同蛋白発現の制御機構をmodifier遺伝子に焦点を当て、網羅的手法を用いて候補modifier遺伝子を同定し、同遺伝子変異をPD2400症例にて検証する。さらに同modifier遺伝子産物機能発現をalpha-synucleinopathy剖検脳・培養細胞にて機能を確認・実証し、alpha-synuclein発現調節機構の全貌に迫る。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

Affymetrix社のGene chip(Genome-wide hyman SNP array 6.0)によるSNCA duplication各家系の解析は終了した.その後,SNP HiTLink v1.5.1を用いてファイルを作成し,MERILINという連鎖解析ソフトを用いてLOD scoreを算出した.LOD 1.0以上の候補領域は1680程リストアップされ,そのデータをもとにUCHC genome browserのデータと比較することにより,高率に脳内発現している遺伝子を2つ絞り込んだ.現在それらの遺伝子についてdirect sequencingを行い,変異の有無の確認を行っている.

Strategy for Future Research Activity

2つの候補領域内に発症している者,していない者の間に何らかの相違が出た場合には,modifier geneの可能性が高く,alpha-synuclienとの関連解析を予定する.具体的には細胞培養実験,モデル動物の作成等である.

Causes of Carryover

研究,解析途中につき,予算が若干余りました.

Expenditure Plan for Carryover Budget

今後は英文校正や追加実験で用いる消耗品等に使用予定です.
