Description
3例の正常脳組織、15例の神経膠芽腫組織、及び3種の神経膠腫細胞株を用いて糖蛋白質糖鎖分析を行った。コントロールとしての3例の正常脳組織(男性:女性=2:1、平均年齢55.2)は、てんかん性の手術を受けた患者からインフォームドコンセントを得て組織を収集した。また、15例の神経膠芽腫組織は、新潟大学病院で神経膠芽腫を有する患者(表1参照)からインフォームドコンセントを得て組織を収集した。
HPLCの結果神経膠芽腫に含有され、正常脳では検出されなかったA2G2Fに対して、レクチン染色を行った。細胞においてLCAレクチンが特異的に結合するfucosylated α1−6GlcNAc構造は、0.1%以上存在する糖鎖構造の中でA2G2Fのみであったことから、コア(core)のα1,6-fucosylation構造に特異的に結合するLCA(レンズマメレクチン;Seikagaku Corporation,Tokyo,Japan)を使用した。
U251,T98G (Riken Cell Bank,Tsukuba,Japan)、及び神経膠芽腫患者組織から培養されたON−12神経膠腫細胞株を10%のFCS,50mMの2−メルカプトエタノール,10mMのヘペス(Hepes)(pH 7.4),2mMのグルタミン,100U/mlのペニシリン, 100μg/mlのストレプトマイシンを含むMEM培地 (Invitrogen, Tokyo,Japan)中で培養したものを試料として使用した。
Claims (3)
