Research Abstract

免疫グロブリンH(IgH)鎖遺伝子とリンパ腫関連遺伝子をプローブにして、間期核double-colorFISH(DC-FISH)法によって非ホジキンリンパ腫173例を検索し、70例(40.5%)にIgH転座を検出した。うち52例(74.3%)で相手遺伝子が同定でき、BCL2が19例、BCL6が16例、BCL1が11例、c-MYCが7例、PAX-5が2例であった。これらの相手遺伝子とWorkingFormulationの組織型との対応は乏しかったが、REAL分類では明確な対応の認められる病型があった。マントル細胞リンパ腫と診断された5例はすべてBCL1/IgH転座が陽性であり、PAX-5/IgH転座陽性の2例はlymphoplasmacytoid lymphomaであった。従って、IgH遺伝子の転座相手をFISHで検出することによって、REAL分類によるリンパ腫の診断をより正確に行うことができると考えられる。一方、IgH遺伝子転座の相手染色体が不明であった14q+をspectral karyotyping法で解析し、t(10;14)を2例、t(2;14)と11q13を切断点としないt(11;14)を各1例、同定できた。
次に、MALTリンパ腫に特異的なt(11;18)(q21;q21)の18q21からMALT1を単離した。MALT1はリンパ造血細胞に優位に発現、免疫グロブリンのスーパーファミリーに属する構造を持ち、接着分子として機能している可能性がある。MALT1領域と11q21をカバーする人工酵母染色体をプローブにするDC-FISHによって、t(11;18)を間期核で検出する方法を確立した。B-NHL39例のうち4例(肺MALTリンパ腫3例と胃MALTリンパ腫1例)と、12例のマクログロブリン血症のうち1例でt(11;18)を検出した。
