1.RNAヘリカーゼによる癌化形質促進作用
RNAヘリカーゼとは、遺伝子から転写されたmRNAの転写開始点から開始コドンまでの5’-untranslated region（5’-UTR）に生じている高次構造を解消する酵素タンパク質である。すなわち、翻訳を担っているリボソームが開始コドンを効率よく認識するためにものであり、タンパク質の翻訳効率に大きな役割を担っているものである。我々はヒト癌細胞において高発現しているRNAヘリカーゼ、YTHDC2（Y2）のクローニングに成功した。そこで、大変興味深いことにY2分子の発現を抑制したヒト癌細胞を移植すると、転移が抑制された。我々はY2が癌転移に関わる遺伝子群のmRNAの高次構造の解消に働いていると考えている。具体的には、癌転移の起因に係わる低酸素ストレスの応答を担う遺伝子群の翻訳に係わるY2分子の役割について解析を進めている。

2.自己抗原になりやすい構造特性はあるのか？
全身性エリテマトーデス（SLE）や慢性関節リウマチなどの自己免疫疾患は理論的に、全身性の細胞性・体液性免疫の破綻が考えられるが、実際には臓器特異的な障害が共通な自己抗体によって起因している場合が多い。すなわち病態の多様性に対して自己抗体のレパートリーの多様性がそれほどなく、おそらく抗原性獲得のための構造を内在している可能性がある（抗原になりやすい構造）。我々はそれを解き明かしたい。現在、マウス常染色体由来のマイナー抗原分子、IL-4 inducible gene 1 (IL4I1)が抗原提示細胞、樹状細胞内での抗原提示経路について解明しており、抗原提示阻害物質の発見を通じ、抗原提示には特異的な小胞体輸送分子が係わっていることを証明した。今後はその分子機構について明らかにしていきたい。

どんなに小さい一歩でも、自分で踏み出さない限り、決して前には進みません。どんなに、どんなに小さくても、昨日よりは前に進みたい、と言う気持ちでいます。
