Definitions

  • the present invention relates to a DNA involved in apoptosis, a polypeptide encoded by the DNA, and an antibody recognizing the polypeptide.
  • Apoptosis refers to cell death in which cells that are no longer needed or have become abnormally self-destruct because the tissue retains its normal shape and function in the living body. For example, removal of unwanted cells during morphogenesis of developing tissues and organs and formation of neural networks, removal of old cells when cells in each tissue are replaced by new cells, elimination of immune cells that react to themselves, Apoptosis works to remove virus-infected cells.
  • Apoptotic cells are characterized by the accumulation of chromatin in the nucleus. The cells themselves contract and die, and are eliminated by phagocytic cells without inflammation. At this time, chromatin DNA is fragmented, and a ladder-like pattern is observed upon electrophoresis.
  • Apoptosis is cell death that is necessary for the body tissue to maintain its normal form and function, and is strictly controlled by various genes in the body. Therefore, it is considered that the abnormalities in the control have a great effect on the living body.
  • Nerve cells are strictly controlled by proliferation, elongation, and apoptosis from the developmental stage, and it is thought that the control forms a nerve network by nerve cells. Nerve cells cease to proliferate after differentiation, but survive for a long time. In recent years, it has been known that apoptosis is also involved in many pathological cell deaths in nerve cells. For example, neuronal necrosis due to cerebral ischemia In addition, death of a large number of nerve cells due to apoptosis has been observed along with necrosis [Journal of Cerebral Blood Flow and Metabolism, 16, 186 (1996), Stroke, 26, 1252 (1995)].

  • p53 [Proc. Natl. Acad. Sci. USA, 91, 7525 (1994)] arrests the cell cycle. In addition to controlling the cell cycle by this activity, it is thought to act to stop the cycle of cells damaged by radiation, drugs and the like, and to induce apoptosis. It is thought that if p53 becomes abnormal, the damaged cells will proliferate as they are, causing cancer. The mechanism of apoptosis induction of p53 is not yet known.

新規アポトーシス関連 D N A 技術分野  New apoptosis-related DNA
本発明は、 アポトーシスに関与する D N A、 該 D N Aのコードするポリべプチ ドおよび該ポリべプチドを認識する抗体に関する。  The present invention relates to a DNA involved in apoptosis, a polypeptide encoded by the DNA, and an antibody recognizing the polypeptide.
背景技術 Background art
アポトーシスは生体において組織が通常の形態や機能を保持していくために、 不要となった、 あるいは異常を起こした細胞が自ら自己破壊を起こす細胞死を意 味する。 例えば、 発生期の組織や器官の形態形成および神経ネッ トワーク形成時 の不要な細胞の除去、 各組織の細胞が新しい細胞に交替する際の古い細胞の除去、 自己に反応する免疫細胞の排除、 ゥィルス感染細胞の除去等にはアポト—シスが 働いている。  Apoptosis refers to cell death in which cells that are no longer needed or have become abnormally self-destruct because the tissue retains its normal shape and function in the living body. For example, removal of unwanted cells during morphogenesis of developing tissues and organs and formation of neural networks, removal of old cells when cells in each tissue are replaced by new cells, elimination of immune cells that react to themselves, Apoptosis works to remove virus-infected cells.
アポトーシスを起こした細胞は核でのクロマチンの凝縮が起こることが特徴的 であり、 細胞自身も収縮して死に、 炎症を起こさずに貪食細胞に除去される。 こ の際クロマチン D N Aが断片化し、 電気泳動にかけ梯子状のパターンが観察され る。  Apoptotic cells are characterized by the accumulation of chromatin in the nucleus. The cells themselves contract and die, and are eliminated by phagocytic cells without inflammation. At this time, chromatin DNA is fragmented, and a ladder-like pattern is observed upon electrophoresis.
アポトーシスは生体の組織が通常の形態や機能を保持していくために必要な細 胞死であり、 生体内の種々の遺伝子によって厳密に制御されている。 従って、 該 制御の異常による生体への影響は多大であると考えられている。  Apoptosis is cell death that is necessary for the body tissue to maintain its normal form and function, and is strictly controlled by various genes in the body. Therefore, it is considered that the abnormalities in the control have a great effect on the living body.
神経細胞は、 発生段階より、 増殖、 伸長およびアポトーシスによる厳密な制御 を受けており、 該制御により、 神経細胞による神経ネッ トワークが形成されると 考えられている。 神経細胞は、 分化後には増殖が停止するが、 生存は長期に渡つ て維持される。 近年になって、 神経細胞における多くの病理的な細胞死にもアポ ト一シスが関与することが知られてきた。 例えば、 脳虚血による神経細胞の壊死 において、 ネクローシスとともに、 アポトーシスによる多数の神経細胞の死が観 察されている [Journal of Cerebral Blood Flow and Metabolism, 16, 186 (19 96)、 Stroke, 26, 1252 (1995)] 。 また、 進行的に神経細胞が脱落減少していく ような疾患、 例えば、 アルツハイマー病 [Experimental Neurology, 133- 225 ( 1995)] 、 パーキンソン病 [Journal of Neurological Sciences, 137, 120 (199 6)〕 、 ハンチン ト ン舞踏病 [Experimental Neurology, 133, 265 (1995)、 Neuro report, 6, 1053 (1995)、 Journal of Neuroscience, 1_5, 3775 (1995)] 、 筋萎 縮性側索硬化症 [Neuropathology and Applied Neurobiology, 21, 498 (1995) 〕 等において、 神経細胞にアポトーシスが起きていることが報告されている。 アルツハイマー病で細胞に蓄積し、 病態に深く関与していると考えられている アミロイ ド βぺプチドは神経細胞死を引き起こすが、 このアミロイ ド/?ぺプチド による細胞死もアポトーシスであり 〔Pro Natl.

USA, 90, 7951 ( 1993)〕 、 ヒ ト免疫不全症ウ ィルス (H I V) 感染による神経細胞死もアポトー シスによるものであると報告されている [American Journal of Pathology, 146, 1121 (1995)、 Acta Neuropathologies, 91, 169 (1996)〕 。 Nerve cells are strictly controlled by proliferation, elongation, and apoptosis from the developmental stage, and it is thought that the control forms a nerve network by nerve cells. Nerve cells cease to proliferate after differentiation, but survive for a long time. In recent years, it has been known that apoptosis is also involved in many pathological cell deaths in nerve cells. For example, neuronal necrosis due to cerebral ischemia In addition, death of a large number of nerve cells due to apoptosis has been observed along with necrosis [Journal of Cerebral Blood Flow and Metabolism, 16, 186 (1996), Stroke, 26, 1252 (1995)]. In addition, diseases in which neurons are progressively lost, such as Alzheimer's disease [Experimental Neurology, 133-225 (1995)], Parkinson's disease [Journal of Neurological Sciences, 137, 120 (1996)], Huntington's chorea [Experimental Neurology, 133, 265 (1995), Neuro report, 6, 1053 (1995), Journal of Neuroscience, 1_5, 3775 (1995)], Amyotrophic lateral sclerosis [Neuropathology and Applied Neurobiology, 21, 498 (1995)], etc., report that apoptosis occurs in nerve cells. Amyloid β-peptide, which accumulates in cells in Alzheimer's disease and is thought to be deeply involved in the pathogenesis, causes neuronal cell death, and cell death by this amyloid / peptide is also apoptosis [Pro Natl Acad. Sci. USA, 90, 7951 (1993)], and neuronal cell death due to human immunodeficiency virus (HIV) infection has also been reported to be due to apoptosis [American Journal of Pathology, 146, 1121 (1995), Acta Neuropathologies, 91, 169 (1996)].
神経細胞のアポトーシスを制御する遺伝子とその機構については、 神経細胞に 実験的にアポト一シスを誘導することによりいく らか解明されてきた。  The genes controlling neuronal apoptosis and their mechanisms have been elucidated somewhat by experimentally inducing apoptosis in neurons.
例 は、 b c 1 — 〔B cell lymphoma / leukemia- 2 gene、 science, 258, 3 02 (1992)、 Pro Natl. Acad. Sci. USA, 90, 4533 (1993)〕 はアポトーシスを 抑制する働きを持つ蛋白の遺伝子であり、 個体発生の際の形態形成などにも関与 していると考えられている。 多様なガン細胞で該遺伝子が過剰発現されているこ とがわかり, 抗ガン剤開発の標的となっている。 該 b e 1 — 2のアンチセンス - オリゴ DN Aを用いることによ り、 動物実験でヒ トの結腸ガンの成長を抑止させ ることができることを米国 Genta社は証明している (日経バイォ最新用語辞典、 日経 B P社 1 9 9 5年) 。  For example, bc 1 — [B cell lymphoma / leukemia-2 gene, science, 258, 302 (1992), Pro Natl. Acad. Sci. USA, 90, 4533 (1993)] has an inhibitory effect on apoptosis It is a protein gene that is thought to be involved in morphogenesis during ontogeny. This gene was found to be overexpressed in various cancer cells, and has become a target for anticancer drug development. Genta has shown that the use of the be1-2 antisense-oligoDNA can inhibit the growth of human colon cancer in animal studies. Dictionary, Nikkei Business Publications, 1995).
p 53 [Proc. Natl. Acad. Sci. USA, 91, 7525 (1994)] は細胞周期を止め る活性を有する力 該活性による細胞周期の制御に加え、 放射線、 薬剤などによ る傷を受けた細胞の周期を停止させたり、 アポトーシスを引き起こさせるのに働 いていると考えられている。 p 53が異常をきたすと損傷を受けた細胞がそのま ま増殖することとなり、 ガンが発生すると考えられている。 p 5 3のアポトーシ ス誘導機構はまだ知られていない。 p53 [Proc. Natl. Acad. Sci. USA, 91, 7525 (1994)] arrests the cell cycle. In addition to controlling the cell cycle by this activity, it is thought to act to stop the cycle of cells damaged by radiation, drugs and the like, and to induce apoptosis. It is thought that if p53 becomes abnormal, the damaged cells will proliferate as they are, causing cancer. The mechanism of apoptosis induction of p53 is not yet known.

USA, 93, 5635 (1996)] に関する報告がある。 しかしながら、 これらの分子に よるアポトーシス誘因の情報伝達機構は解明されていない。 USA, 93, 5635 (1996)]. However, the signaling mechanism of these molecules to induce apoptosis has not been elucidated.
