Research Abstract	進行胃癌例の食欲不振の原因として胃癌が産生し、血中に存在するレプチンが重要な役割を有しているか否かを明らかとするための検討を行っている。対象には進行胃癌患者を用い、血清中のレプチンをELISAにて、胃癌組織中のレプチンmRNAをreal time quantitative PCRによって測定し、visual analogue scaleを用いた胃癌患者の食欲の障害の程度の評価を行った。健常者に比較して進行胃癌例の血清中レプチンは高い傾向が認められたが、検討症例数がまだ少ないためか有意な差にはいたらなかった。胃癌組織からtotal RNAを抽出し、real time quantitative PCRを用いレプチンmRNAを測定すると、種々の量のレプチンmRNAが胃癌組織中で産生されていることが明らかとなった。次いで胃癌の進展度、組織型、Helicobacter pylori感染の有無と胃癌組織中mRNA量、血清レプチンレベルに関係があるか否かの検討を行ったが明らかな関係は認められなかった。また胃癌組織中レプチンmRNA量と血清レプチン、食欲障害の程度に関しても現在検討終了した症例数では明らかな相関関係は認められなかった。そこで来年度検討症例数を増加して検討を行うとともに、レプチンのObRbを介した胃癌細胞増殖に及ぼす効果について検討をすすめる予定である。
