本発明の第1の局面は褐色脂肪細胞分化誘導剤(以下、説明の便宜上「分化誘導剤」とも呼ぶ)に関する。「褐色脂肪細胞分化誘導剤」とは、褐色脂肪細胞への分化能を有する細胞(即ち前駆細胞又は幹細胞。典型的には、筋・褐色脂肪前駆細胞又は脂肪前駆細胞)に作用し、褐色脂肪細胞に分化するように働きかける薬剤をいう。褐色脂肪細胞分化誘導剤を使用すると、褐色脂肪細胞への分化が促進される結果、褐色脂肪細胞数が増大する。
CREG1は分泌型糖タンパク質であり、細胞の増殖や分化に関与することが知られているものの(Veal E, Eisenstein M, Tseng ZH, Gill G. Mol Cell Biol. 1998 Sep;18(9):5032-41.、Di Bacco, A., Gill, G. Oncogene (2003)、Sacher, M., Di Bacco, A., Lunin, V.V., Ye, Z., Wagner, J., Gill, G., Cygler, M. Proc. Natl. Acad. Sci. U.S.A. (2005)等を参照)、その生理学的役割の詳細は不明である。CREG1のアミノ酸配列及びそれをコードするヌクレオチド配列をそれぞれ配列表の配列番号1(GenPept(NCBI), ACCESSION: NP_003842, DEFINITION: protein CREG1 precursor [Homo sapiens].)及び配列番号3(GenBank(NCBI), ACCESSION: NM_003851, DEFINITION: Homo sapiens cellular repressor of E1A-stimulated genes 1 (CREG1), mRNA.)に示す。
本発明の一態様では、CREG1遺伝子を保持する発現ベクターを有効成分とする。「発現ベクター」とは、それに挿入された核酸を目的の細胞(宿主細胞)内に導入することができ、且つ当該細胞内において発現させることが可能なベクターをいう。本発明に係る発現ベクターでは、CREG1遺伝子が発現可能に保持されることになる。CREG1遺伝子を標的細胞に導入し、標的細胞内で発現させることが可能である限り、ベクターの種類は特に限定されない。ここでの「ベクター」にはウイルスベクター及び非ウイルスベクターが含まれる。ウイルスベクターを用いた遺伝子導入法は、ウイルスが細胞へと感染する現象を巧みに利用するものであり、高い遺伝子導入効率が得られる。ウイルスベクターとしてアデノウイルスベクター、アデノ随伴ウイルスベクター、レトロウイルスベクター、レンチウイルスベクター、ヘルペスウイルスベクター、センダイウイルスベクター等が開発されている。
褐色脂肪細胞は中性脂肪を燃焼して過剰エネルギーを消費する特殊な細胞であり、その減少が肥満やメタボリック症候群発症の原因となることが明らかとなってきた。従って、褐色脂肪細胞を増加させることは、肥満やメタボリック症候群など、代謝異常やその関連疾患の予防・治療に有効な手段となる。そこで本発明の第2の局面は、代謝異常又はその関連疾患の治療又は予防用の組成物を提供する。
本発明の組成物は、好ましくは医薬、医薬部外品又は食品の形態で提供される。即ち、本発明は好ましい態様として、本発明の分化誘導剤を有効成分として含有する医薬組成物、医薬部外品組成物及び食品組成物を提供する。本発明の組成物の治療ないし予防対象となる「代謝異常又はその関連疾患」(以下、説明の便宜上「標的疾患」と呼ぶ)の具体例は、肥満、糖尿病、脂質異常症、動脈硬化性疾患、メタボリック症候群である。ここで「肥満」とは一般的には体内に脂肪組織が過剰に蓄積した状態をいう。本明細書では用語「肥満」は広義に解釈されるものとし、その概念に肥満症を含む。「肥満症」とは肥満に起因ないし関連する健康障害(合併症)を有するか又は将来的に有することが予測される場合であって、医学的に減量が必要とされる病態をいう。肥満の判定法には、例えば、国際的に広く使用されているBMI(body mass index)を尺度としたものがある。BMIは、体重(kg)を身長(m)の二乗で除した数値(BMI=体重(kg)/身長(m)2)である。BMI<18.5は低体重(underweight)、18.5≦BMI<25は普通体重(normal range)、25≦BMI<30は肥満1度(preobese)、30≦BMI<35は肥満2度(obese class I)、35≦BMI<40は肥満3度(obese class II)、40<BMIは肥満4度(obese class III)と判定される(WHO)。また、BMIを利用して、日本人の成人の標準体重(理想体重)を以下の式、標準体重(kg)=身長(m)2×22から計算し、実測体重が標準体重(計算値)の120%を超える状態を肥満とする判定法もある。もっとも、標準体重(理想体重)は性別、年齢、又は生活習慣の差異などによって個人ごとに相違することから、肥満の判定をこの方法で一律に行うことは妥当でないと考えられている。

本発明の第3の局面は褐色脂肪細胞分化誘導物質をスクリーニングする方法に関する。本発明のスクリーニング方法によって選抜された化合物は、褐色脂肪細胞分化誘導剤の有効成分として有望であり、代謝異常又はその関連疾患の治療や予防に利用され得る。本発明のスクリーニング方法では、「CREG1の発現増強が、褐色脂肪細胞への分化を誘導する手段として有効である」との知見に基づき、「CREG1の発現レベルの上昇が認められること」を指標として被験物質の有効性を判断する。即ち、本発明のスクリーニング方法は、CREG1の発現レベル上昇作用を被験物質が示すか否かを調べることを特徴とする。本発明の一態様では、以下のステップを実施する。
(i)CREG1が発現している細胞を被験物質存在下で培養するステップ;
(ii)前記細胞におけるCREG1の発現レベル又は分泌レベルを測定するステップ;及び
(iii)測定結果に基づき被験物質の有効性を判定するステップであって、CREG1の発現レベル又は分泌レベルの上昇が認められることが有効性の指標となるステップ。
1.褐色脂肪細胞の分化誘導因子の探索
寒冷環境下でマウスやラットを飼育すると、褐色脂肪細胞の分化が刺激され、褐色脂肪組織が増大することが知られている。そこで、C57BL6マウスを5℃環境下で1週間飼育した(寒冷暴露)後、肩甲骨間から褐色脂肪組織を採取し、全RNA分画を調製した。コントロールとして、寒冷暴露しないマウスからも同様に褐色脂肪組織の全RNA分画を調製した。次に、全RNA分画から合成したcDNAを用いて、UCP1とCreg1のmRNA発現量を定量PCR法により測定した。コントロール遺伝子として同様に測定した36B4 mRNAの発現量によりノーマライズした結果(n=4)を図1に示す。従来の報告通り、寒冷暴露によって褐色脂肪組織が発達しUCP1遺伝子の発現量が約10倍に上昇した。同様に、Creg1遺伝子の発現量も寒冷暴露により4倍以上に上昇することが明らかとなった。
C57BL6マウスから採取した皮下白色脂肪組織を0.2%コラゲナーゼを含む組織消化液中にて37℃、30分間処理した後、2種類(口径70μm及び40μm)のナイロンフィルターを用いて組織消化液をろ過した。ろ液を170 gで6分間遠心分離し、沈殿した細胞分画を得た。次に、これらの初代細胞を30,000個/穴で24穴プレートに播種し、10%牛胎児血清を含むDMEM培地中(10%FBS/DMEM)において37℃、5%CO2インキュベーター内にて培養した。2日後、分化培地(0.5mM IBMX, 1μM デキサメタゾン, 10μg/ml インスリン, 125nM インドメタシン, 1nM T3, 1μM Pioglitazoneを含む10%FBS/DMEM)に培地交換して褐色脂肪細胞への分化を誘導した。分化誘導前を0日として1、2、4、6、8、10、12日目に細胞から全RNA分画を調製した。全RNA分画から合成したcDNAを用いてUCP1とCreg1のmRNA発現量を定量PCR法により測定した。コントロール遺伝子として同様に測定した36B4 mRNAの発現量によりノーマライズした結果(n=3)を図2に示す。
Creg1の過剰発現が褐色脂肪細胞の分化誘導に与える影響を検討するため、レトロウイルスベクターpMXを用いる実験系を構築した。pMX-GFP(コントロール)またはpMX-Creg1をPLAT-E細胞にトランスフェクションし、それぞれのウイルス液を作製した。次に、2.と同様に準備しておいた皮下白色脂肪組織由来の初代前駆脂肪細胞培養系にウイルス液を加え、翌日培地交換した後、褐色脂肪細胞への分化誘導を行った。5日後に、細胞から全RNA分画を調製し、合成したcDNAを用いてUCP1とCreg1のmRNA発現量を定量PCR法により測定した。コントロール遺伝子として同様に測定した36B4 mRNAの発現量によりノーマライズした結果(n=6)を図3に示す。
2.と同様に、皮下白色脂肪組織由来の初代前駆脂肪細胞培養系を用いてCreg1のsiRNA遺伝子ノックダウン実験を行い、褐色脂肪細胞分化誘導に対する影響を検討した。具体的には、24穴プレートに播種した初代細胞が約50〜70%コンフルエントとなった後、Invitrogen社のCreg1ノックダウン用Stealth RNAiをLipofectoamine RNAi MAX試薬を用いて細胞に導入した。翌日培地交換し、2日目から褐色脂肪細胞への分化誘導を行った。5日後に、細胞から全RNA分画を調製し、合成したcDNAを用いてUCP1とCreg1のmRNA発現量を定量PCR法により測定した。コントロール遺伝子として同様に測定した36B4 mRNAの発現量によりノーマライズした結果(n=6)を図4に示す。
Creg1遺伝子の褐色脂肪細胞分化における作用を個体レベルで検証するために、Creg1遺伝子発現アデノウイルスベクター系(Ad-Creg1)を構築した。Ad-LacZ(コントロール)またはAd-Creg1を293A細胞にトランスフェクションして調製したアデノウイルス(約3x1010 pfu/20μl)をマウスに皮下注射し、一週間後に各脂肪組織から全RNA分画を調製し、合成したcDNAを用いてUCP1 mRNA量を定量PCR法により測定した。コントロール遺伝子として同様に測定した36B4 mRNAの発現量によりノーマライズした結果(n=4)を図5に示す。コントロールに比べて、Creg1発現アデノウイルスを投与したマウスの褐色脂肪組織(A: BAT)においてCreg1 mRNA量は約2倍に上昇したが、UCP1発現量の上昇は15%程度に留まった。一方、内臓白色脂肪組織(B: GWAT)におけるCreg1 mRNA量の上昇は10%程度であったが、UCP1 mRNA量はコントロールの約13倍に上昇していることが明らかとなった。この結果は、内臓白色脂肪組織において褐色脂肪細胞の分化が顕著に誘導されたことを示すものである。また、この内臓白色脂肪組織における褐色脂肪細胞の分化誘導は組織学的検討からも確認された(結果省略)。同様に、Ad-LacZ(コントロール)またはAd-Creg1発現アデノウイルス(約1.6x109 pfu/マウス)をマウスの鼠蹊部白色脂肪組織に注射して一週間後にその白色脂肪組織から全RNA分画を調製し、合成したcDNAを用いてUCP1と36B4 mRNA量を定量PCR法により測定した(n=4)。コントロールに比べて、Creg1発現アデノウイルスを投与したマウスの鼠蹊部白色脂肪組織(C:IWAT)においてCreg1 mRNA量は約1.6倍に上昇し、UCP1発現量は約2.4倍に上昇した(図5(C))。この結果は、鼠蹊部白色脂肪組織においてCreg1を発現誘導することにより褐色脂肪細胞の分化が促進されたことを示すものである。
a)精製Creg1蛋白質の調製
哺乳動物細胞における蛋白質発現プラスミドpcDNA3.1にマウスCreg1 cDNAを挿入し、このCreg1発現ベクターをサル腎臓由来Cos7細胞に遺伝子導入した。Creg1発現ベクターを導入したCos7細胞において天然型マウスCreg1を安定的に産生する細胞を選別し、精製Creg1蛋白質調製用細胞とした。次に、この細胞を大量培養して得られた培養上清中に分泌されるCreg1を精製し天然型マウスCreg1を調製した。また、組換え型マウスCreg1は大腸菌における蛋白質発現プラスミドpET-21に挿入し、このCreg1発現ベクターを大腸菌に遺伝子導入した。Creg1発現ベクターを導入した大腸菌を大量培養し、得られた培養液からCreg1を精製し、組換え型マウスCreg1を調製した。
8週齢の雄性ApoE欠損動脈硬化モデルマウスに対して、麻酔下にてAd-LacZ(コントロール)またはAd-Creg1アデノウイルスを尾静脈より投与し(約1.5x109 pfu/マウス)、高脂肪食摂取下において2週間体重変化を観察した。2週間後にマウスを屠殺し、各組織を採取した。尚、Creg1蛋白質投与実験の代わりとして、アデノウイルスベクターを用いて生体内で天然型Creg1蛋白質の発現を誘導し、その効果を個体レベルで検討することにしたが、この方法では、アデノウイルスベクターの特性として目的蛋白質は主に肝臓で産生されて血中に分泌されることになる。マウス生体内におけるCreg1遺伝子の発現分布の検討から、Creg1産生の主要臓器の一つは肝臓と考えられることから、アデノウイルスベクターを用いる方法は本来Creg1が産生される組織における発現を増強するものとなる。以上の理由から、アデノウイルスベクターを用いるCreg1発現誘導法は、生体内においてCreg1レベルを上げるという目的において、Creg1蛋白質の投与実験と類似の結果を得られることが期待され、実験室レベルにおいて妥当な代替実験法と考えられる。
