Description
A.Beishuizenら、「Endogenous Mediators in Sepsis/and Septic Shock」、Advances in Clinical Chemistry、Vol.33、1999、55-131 C.Gabayら、「Acute Phase Proteins and Other Systemic Responses to Inflammation」、The New England Journal of Medicine、Vol.340、No.6 1999、448-454 K.Reinhartら、「Sepsis und septischer Schock」[Sepsis and septic shock]、in Intensivmedizin、Georg Thieme Verlag、Stuttgart、New York、2001、756-760 M.Assicotら、「High serum procalcitonin concentrations in patients with sepsis and infection」、The Lancet、Vol.341、No.8844、1993、515-518
GNATの発見および同定を、添付の配列表を参照して下記にさらに詳細に説明する。
内毒素の注射によってプロカルシトニン分泌を刺激する、複数のヒヒで実施された実験に基づいて(H.Redlら「外傷および敗血症のヒヒモデルにおけるプロカルシトニン分泌パターン:サイトカインおよびネオプテリンに対する関係」「procalcitonin release pattern in a baboon model of trauma and sepsis:relationship to cytokines and neopterin」、Crit Care Med 2000、Vol.28、No.11、3659-3663;およびH.Redlら、「敗血症の非ヒト霊長類モデル」「Non-Human Primate Models of Sepsis」in:Sepsis 1998;2:243-253参照)、複数のヒヒ(雄、約2歳、27〜29kg)それぞれに、体重kgあたり100μgのLPS(サルモネラティフィムリウム由来のリポポリサッカライド:供給源はシグマ)を静脈内投与した。投与5〜5.5時間後に、10mlのドレータルを静脈内投与して動物を犠牲にした。その死から60分以内に、すべての器官および組織を切開し、液体窒素で凍らせることによって安定化した。
一方では、複数の健常なヒヒ(対照)、他方では、LPSが注入されている複数のヒヒの肝臓細胞の複数の細胞質タンパク抽出物をプロテオーム分析に使用した。初回の2次元ゲル電気泳動分析では、タンパク100μgを含む肝臓抽出物を、9M尿素、70mMDTT、2%両性電解質、pH2〜4に対して安定化させ、次に2次元ゲル電気泳動分析で、J.Kloseら(「タンパクの2次元電気泳動:ゲノムの機能的分析の最新プロトコルおよび含意」、「Two-dimensional electrophoresis of proteins:An updated protocol and implications for a functional analysis of the genome」、Electrophoresis 1995、16、1034-1059)に記載のように分離した。2次元電気泳動ゲルにおけるタンパクの視覚化は、銀染色(J.Huekeshovenら「ファストシステム開発ユニットIにおける高速染色のための改良銀染色手順:ソディウムドデシルゲルの染色」「Improved silver staining procedure for fast staining in Phast-System Development Unit.I.Staining of sodium dodecyl gels」、Electrophoresis 1988、9、28-32)で行った。
図1(A)および1(B)に示すように、LPSの注入物が予め投与されている複数のヒヒの肝臓細胞抽出物が、とりわけ新規タンパクを含んでいた。このタンパクは、ゲル電気泳動のデータを基にして既知分子量のマーカー物質と比べて、分子量が約37000±700ダルトンであると推定され、一方、1次元のタンパク相対的位置から等電点が約7.0から8.0であると推定された。
