研究内容
卵巣子宮内膜症と正常子宮内膜における遺伝子変異解明
子宮内膜症は子宮内膜に似た組織が子宮以外の組織に生着・増殖し、月経周期に応じて出血や疼痛をきたす疾患で、生殖年齢にある女性の約10%が罹患すると言われています。月経困難症、骨盤痛や不妊症との関連も指摘されており、少子化や女性の社会進出の障害として、社会的損失が大きい疾患です。子宮内膜症が最も多く発症する部位は骨盤腹膜や卵巣です。また、疫学研究により子宮内膜症が特定の組織型の卵巣がん(明細胞腺がん、類内膜がん)の発症リスクになることが報告されています。しかし、卵巣がんの発症母地(前がん病変)とされる卵巣子宮内膜症におけるゲノム変異については明らかにされていませんでした。 そこで、私たちは卵巣子宮内膜症および正常子宮内膜におけるゲノム解析を行い、良性腫瘍である子宮内膜症のみならず正常子宮内膜においても、多数のがん関連遺伝子に変異が存在することを明らかにしました。特に子宮内膜症と関連する卵巣がんで高頻度に認められるKRAS、PIK3CA、FBXW7、PPP2R1A、PIK3R1、ARID1Aの変異が多く認められました。発がんドライバーであるがん関連遺伝子変異が認められたにもかかわらず、これら上皮細胞において病理学的な形態異常は認められませんでした。また、子宮内膜症上皮において、がん関連遺伝子変異、特に卵巣がんで変異頻度の高いKRASおよびPIK3CAに変異を保有する上皮細胞がクローン性に増殖していることが分かりました。 さらに、正常子宮内膜上皮細胞が管状構造(図1)を呈して発達していることに着目し、単一腺管レベルという最小機能単位で体細胞変異プロファイリングを行いました。その結果、正常な子宮内膜から採取した腺管において、KRAS やPIK3CAを含むがん関連遺伝子に体細胞変異が多数検出されました。興味深いことに、各腺管で保有する変異はクローナルな状態に達していましたが、腺管ごとに異なる体細胞変異を保有していました。つまり、子宮内膜組織は、個々に異なる体細胞変異を有する腺管が集合して構成される組織であるため、ゲノムがモザイク状態を呈することが分かりました。これらの結果は、モザイク状ゲノムを呈する子宮内膜が月経血逆流を介して卵巣に生着・増殖する過程で、KRASなどのがん関連遺伝子変異を有する上皮細胞が生存に有利となり、クローナルに増殖することで、子宮内膜症発症に至ることを示唆しています。我々の解析結果は卵巣子宮内膜症発症における月経逆流説をゲノムレベルで支持するものとなりました(図1)。 ヒト正常子宮内膜に存在するがん関連遺伝子変異の機能的影響は未解明です。私たちの研究によって、がん関連遺伝子に体細胞変異を有する細胞クローンが子宮内膜組織において正の選択を受けていることが分かりました。しかし、そのような細胞クローンが存在していても、ほとんどの女性が婦人科がんを発症するには至りません。がん関連遺伝子変異を有する細胞クローンはがん化の危険性という負の側面だけではなく、子宮内膜のように月経周期に応じて再生を繰り返す組織において、増殖能の高い腺管が組織維持に役立っている可能性も考えられます。がん関連遺伝子変異を保有する正常子宮内膜の詳細なゲノム解析を通じて、がん化を抑え、生体を維持する分子機構を解明するための研究に取り組んでいます。 また、子宮内膜だけではなく、肺、胃、食道、皮膚といった他の組織においても、正常細胞における体細胞変異とがん化に関する研究を進めています。様々な正常組織におけるがん関連遺伝子変異の探索・機能的特性を評価することで、組織を越えて共通する分子機構、さらには、組織特有の分子機構を見出すことを目的としています。研究業績(過去5年間)
