本研究では, 肝癌症例の肝癌組織と非癌部肝組織, 肝癌を合併しない慢性肝疾患組織, コントロール肝組織を対象として, それらにおける三種の癌遺伝子c-myc, c-Ki-ras, c-Ha-rasのメチル化状態を比較検討した。肝癌組織18例中13例(72.2%), 非癌部肝組織34例中29例(85.2%), 肝癌を合併しない慢性肝疾患組織34例中25例(73.5%)においてc-myc遺伝子の第2エクソンのCCGG 部位の完全脱メチル化を認めた。一方, コントロール肝組識31例中3例においてのみ同CCGG 部位の完全脱メチル化を認め, 残りの28例に部分的脱メチル化を認めた。完全脱メチル化を認めた患者3例は, 0, 14, 23歳の若年者であり, 一方部分的脱メチル化を認めた患者28例は25歳から83 歳であり, これは肝癌患者および慢性肝疾患患者とほぼ同様の年齢分布であった。また完全脱メチル化を有する頻度は, 肝硬変で肝癌を合併するか否かで明らかな差を認めず, 慢性活動性肝炎でも同様であった。肝癌組織18例中7例(38.9%)にc-myc遺伝子第3エクソンの脱メチル化が生じており, 13例(72.2%)にc-K1-ras遺伝子の脱メチル化が生じており, 非癌部肝組織, 慢性肝疾患組織, コントロール肝組織においては脱メチル化が生じていなかった。肝癌組織13例(72.2%)において同じ症例の非癌部肝組織と比較してc-Ha-ras 遺伝子の脱メチル化が生じていた。また肝癌組織18例中16例(88.9%)において, 三つのうちいずれかの癌遺伝子に脱メチル化が生じていた。c-myc遺伝子第2エクソンのCCGG 部位の脱メチル化は, 持続する肝細胞壊死とそれに対する代償的な再生をきたす慢性肝疾患における病態と関連を有すると考えられる。そこに肝癌が発生する過程でc-myc遺伝子の第3エクソンあるいはc-Ki-ras, c-Ha-ras遺伝子の脱メチル化等が生じると考えられるが, これらの癌遺伝子の脱メチル化が肝癌発生の原因であるのか結果であるのかは, 本研究では明らかにすることが出来なかった。","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_3_description_6":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"富山医科薬科大学医学会誌,
