Keywords頭頸部癌 / AP-1遺伝子群 / 頸部リンパ節転移 / FOSL1
Outline of Annual Research Achievements

今までの研究で頭頸部扁平上皮癌の転移関連遺伝子群として同定したAP-1遺伝子群の中でもFosL1を検証対象として選出し,頭頸部扁平上皮癌の大きな予後因子の一つである頸部リンパ節転移能へのFosL1の関与について検討を行った。
頭頸部扁平上皮癌におけるFosL1発現抑制に伴い,in vitroでは浸潤能,遊走能の低下と,in vivoでは同所性頭頸部癌モデルにおける頸部転移形成の抑制と生存期間の延長を認めた。また,FosL1が制御する遺伝子を探索するため,FosL1発現抑制細胞株とコントロール細胞株を用いてプロテオミクス解析を行い,FosL1の標的遺伝子候補としてHMGA1を選出した。HMGA1発現抑制に伴い,in vitroで遊走能の低下を認め,頭頸部扁平上皮癌において,FosL1は細胞浸潤能,遊走能を亢進することで頸部転移形成を促進し,その制御にHMGA1を介することが示唆された。
