Keywords高比重リポ蛋白 / 動脈硬化 / 全エクソームシーケンス
Outline of Annual Research Achievements

動脈硬化症予防を目的に、症例に立脚した高比重リポ蛋白(HDL)代謝異常症の病態解明を目指した研究を引き続き試みている。発端者は①著明な高HDLコレステロール血症(170mg/dL)と②著明な低HDLコレステロール血症2例である。
②低HDLコレステロール血症患者2人(症例1:28歳女性、HDLコレステロール値2mg/dL、症例2:35歳女性、同6mg/dL)と2人の両親(HDLコレステロール値37mg/dL、41mg/dL)、4人の非血縁正常者(平均HDLコレステロール値107mg/dL)の計8人を対象に全エクソームシーケンスを行った。
305,202個の遺伝子多型が見出され、SnpEffを用い良性変異を除外した結果、21,708個のナンセンス変異、ミスセンス変異、スプライス部変異が同定された。さらに1%以上の頻度を認める変異を除外した結果5,192個の変異に絞られ、劣性遺伝に合致する変異、C-スコア10点未満の変異を除外した結果、ABCA1遺伝子変異c.6230C>A、c.6137G>A、c.2842>A、c.1130C>Tが残り、症例1はc.6230C>A/c.6137G>A、症例2はc.2842>A、c.1130C>Tのそれぞれコンパウンドヘテロ接合体(Tangier病)と診断された(Tada H, Kawashiri M et al. Atherosclerosis 240:324-329;2015)。
劣性遺伝性疾患の遺伝子診断に、全エクソームシーケンス法は有用であった。

Current Status of Research Progress
Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

全エクソームシーケンス法で著明な低HDLコレステロール血症(2、6mg/dL)2例の遺伝子解析を終了した。新規遺伝子ではなかったため機能解析は見送った。
著明な高HDLコレステロール血症(170mg/dL)症例に見出された新規候補「分子X」の機能解析に着手した。遺伝子改変動物を用いた検討は技術的に困難であり、培養細胞を用いたコレステロール引き抜き研究を先行させることにした。

Strategy for Future Research Activity

遺伝子導入細胞を用いたコレステロール引き抜き研究を展開する予定である。本研究は防衛医科大学校の研究グループが過去に行っている。研究がやや遅れており、共同研究を視野に研究を進める方針である。

Causes of Carryover

動物実験による「分子X」機能解析は技術的に困難であるため、培養細胞を用いたコレステロール引き抜き研究を優先させることとした。培養細胞実験の方が安価に実験可能であり、当初計上した予算を余すことが出来た。

Expenditure Plan for Carryover Budget

培養細胞を用いたコレステロール引き抜き研究を防衛大学の研究グループから教わる必要がある。次年度使用額はその旅費や実験消耗品等に充てる予定である。
