    An integrative understanding of nuclear events including transcription in normal and cancer cells requires comprehensive and quantitative measurement of protein dynamics that underlie such events. However, the low abundance of most nuclear proteins hampers their detailed functional characterization. We have now comprehensively quantified the abundance of nuclear proteins with the use of proteomics approaches in both normal and transformed human diploid fibroblasts. We found that subunits of the 26S proteasome complex were markedly down-regulated in the nuclear fraction of the transformed cells compared with that of the wild-type cells. The intranuclear proteasome abundance appeared to be inversely related to the rate of cell cycle progression, with restraint of the cell cycle being associated with an increase in the amount of proteasome subunits in the nucleus, suggesting that the nuclear proteasome content is dependent on the cell cycle. Furthermore, chromatin enrichment for proteomics (ChEP) analysis revealed enrichment of the proteasome in the chromatin fraction of quiescent cells and its apparent dissociation from chromatin in transformed cells. Our results thus suggest that translocation of the nuclear proteasome to chromatin may play an important role in control of the cell cycle and oncogenesis through regulation of chromatin-associated transcription factors.

    Glucose metabolism is remodeled in cancer, but the global pattern of cancer-specific metabolic changes remains unclear. Here we show, using the comprehensive measurement of metabolic enzymes by large-scale targeted proteomics, that the metabolism both carbon and nitrogen is altered during the malignant progression of cancer. The fate of glutamine nitrogen is shifted from the anaplerotic pathway into the TCA cycle to nucleotide biosynthesis, with this shift being controlled by glutaminase (GLS1) and phosphoribosyl pyrophosphate amidotransferase (PPAT). Interventions to reduce the PPAT/GLS1 ratio suppresses tumor growth of many types of cancer. A meta-analysis reveals that PPAT shows the strongest correlation with malignancy among all metabolic enzymes, in particular in neuroendocrine cancer including small cell lung cancer (SCLC). PPAT depletion suppresses the growth of SCLC lines. A shift in glutamine fate may thus be required for malignant progression of cancer, with modulation of nitrogen metabolism being a potential approach to SCLC treatment.

    老化に伴い細胞は特殊な代謝状態を取ることが知られているが、これまで老化代謝を対象にした解析はあまり行われていない。そこで本研究課題では、われわれが独自に開発した次世代プロテオミクス技術(iMPAQTシステム)を駆使して、老化過程で起こるタンパク質発現量変化の網羅的な解析を実施している。本研究の実施・遂行の結果として代謝経路の人為的操作により老化状態を制御することが可能となれば、多くの細胞老化と関わると推定されている種々の疾患の診断や治療あるいは予防に役立つだけでなく、逆に老化を促進することによってがん細胞の撲滅を図る戦略も可能になることが期待できる。
    前年度までに3種類の老化誘導モデル(複製老化、酸化ストレス誘導老化、がん遺伝子誘導老化)の全代謝酵素関連タンパク質の情報基盤多重モニタリング法と、転写産物量の計測を実施した。その結果、3種類の老化細胞に共通する代謝変動パターンと各種老化細胞特異的な代謝ネットワークのリモデリングを見出すことに成功している。
    令和三年度は、3種類の老化細胞で発現が減少していたDNA合成関連酵素群の過剰発現およびノックダウン実験を実施し、代謝酵素量の介入実験による細胞老化の制御が可能かを検証した。このうち、Ribonucleotide reductase subunits (RRM)遺伝子の発現を正常細胞で低下させたところ、細胞の増殖が停止した。このノックダウン細胞を詳細に解析したところ、老化細胞の表現型を示すことを見出した。RRM遺伝子の低下に伴い、p16, p21の発現量の上昇およびLamin B1の発現量の低下していた。また老化マーカーであるSA-β-Gal染色も陽性であった。以上から、DNA合成酵素の発現を低下させることで細胞老化が生じることを明らかにした。

    前年度までにリン酸化ペプチドの精製技術を確立した。21年度は細胞内リン酸化細胞周期の全過程の解析には少なくとも4点以上の定量が必要となるため、多検体間比較定量法を構築した。当初、一般的に質量分析計による定量法として安定同位体標識アミノ酸代謝標識法(SILAC)が主流であり、これを応用した多点定量法の構築を試みたが、使用できる培養細胞が限られるなどの欠点があるため、新規リン酸化定量プロテオミクス法であるphospho-iTRAQ法の構築を試みた。
    iTRAQ法は4種類,あるいは8種類の試料間の同時比較定量が可能であるため、細胞周期など時系列解析に適している。しかしながら、リン酸化の解析に適用する場合、試料の消化・リン酸ペプチドの精製後に標識を行うため、消化や精製過程での誤差が生じやすい。そこで、カゼインなどのリン酸化タンパク質を内部標準として各々の試料に少量添加することで、消化や精製の誤差を補正することを考案した。実際、実験過程で生じる誤差を内部標準由来のリン酸化ペプチドの定量値を用いて補正することが可能であった。本方法を用いて増殖因子刺激や細胞周期進行過程でリン酸化の変動を大規模に解析したところ、約10,000種類以上のリン酸化部位を同定・定量が可能であった。
    得られた新規細リン酸化の細胞周期制御上の意味を検証するため当該タンパク質の機能撹乱やリン酸化部位変異体の導入による細胞周期への影響の検討、さらに、細胞内局在や他のタンパク質との相互作用の細胞周期依存性等を横断的に解析している。

    Factors that determine the spectrum of target organs involved in autoimmune destruction are poorly understood. Although loss of function of autoimmune regulator (AIRE) in thymic epithelial cells is responsible for autoimmunity, the pathogenic roles of AIRE in regulating target-organ specificity remain elusive. In order to gain insight into this issue, we have established NOD mice, an animal model of type I diabetes caused by autoimmune attack against b-cell islets, in which Aire has been abrogated. Remarkably, acinar cells rather than β-cell islets were the major targets of autoimmune destruction in Aire-deficient NOD mice, and this alteration of intra-pancreatic target-organ specificity was associated with production of auto-Ab against pancreas-specific protein disulfide isomerase (PDIp), an antigen expressed predominantly by acinar cells. Consistent with this pathologic change, the animals were resistant to the development of diabetes. The results suggest that Aire is not only critical for the control of self-tolerance but is also a strong modifier of target-organ specificity through regulation of T-cell repertoire diversification. We also demonstrated that transcriptional expression of PDIp was retained in the Aire-deficient NOD thymus, further supporting the concept that Aire may regulate the survival of autoreactive T cells beyond transcriptional control of self-protein expression in the thymus.
