Description
また、特許文献3には、KS及びヒアルロン酸(以下、HAという)をリガンドとする固相プレートを用いたアッセイ方法が記載されている。
従って、本発明の目的は、生体試料中のグリコサミノグリカンを高感度かつ簡便に測定し、ムコ多糖症を正確に診断するための方法を提供することにある。
(A)下記ステップ(1)及び(2)を含む、ムコ多糖症の診断方法。
(1)(a)生体試料を限外濾過フィルターで濾過し、フィルター上でGAG特異的酵素による消化を行なうか、又は(b)生体試料をGAG特異的酵素による消化を行ない、得られた消化物を限外濾過フィルターで濾過した後、
得られた消化物を遠心分離して得られた濾過液を又は得られた濾過液LC/MS/MSへ注入し、GAG由来の二糖について分析するステップ。
(2)(1)の測定結果である定量濃度及び二糖組成を用いて、ムコ多糖症の診断、又はムコ多糖症の各疾患の判別鑑定を行なうステップ。
また、本発明の方法はムコ多糖症の診断の他、前述した治療時における治療効果の把握と治療方針の決定、さらには医薬品開発の薬効評価へも使用することが可能である。
さらに本発明の方法は、GAGに関連する疾患である変形性関節症、慢性関節リウマチ、角膜組織異常を伴う疾患、リウマチなどの炎症、癌、肝疾患におけるバイオマーカー測定法としても有用である。
ΔDiHS−0S:ΔHexA α1→4GlcNAc:
2−acetamido−2−deoxy−4−O−(4−deoxy−α−L−threo−hex−enopyranosyluronic acid)−D−glucose、ΔDiHS−NS:ΔHexA α1→4GlcNS:
2−deoxy−2−sulfamino−4−O−(4−deoxy−α−L−threo−hex−4−enopyranosyluronic acid)−D−glucose、ΔDiHS−6S:ΔHexA α1→4GlcNAc(6S):
2−acetamido−2−deoxy−4−O−(4−deoxy−α−L−threo−hex−4−enopyranosyluronic acid)−6−O−D−glucose、MSD:
Galβ1→3GlcNAc(6S)、DSD:Gal(6S)β1→3GlcNAc(6S)。
本発明のアッセイ法により血漿及び血清を用いたスクリーニングが可能か否かを調べるため、ムコ多糖症の患者血漿とヒトのコントロール血漿を用いて、以下の実験を行なった。
本発明のアッセイ法により尿を用いたスクリーングが可能か否かを調べるため、ムコ多糖症の患者尿とヒトのコントロール尿を用いて、以下の実験を行なった。
三種類のコントロール尿を3日間、N=5で測定した結果を表12及び表13に示す。
特にムコ多糖症IV A型(表14内No.16〜18)とIV B型(表14内No.19〜21)ではKS由来のDSD比率が異なる。すなわちIV A型ではDSDの高い比率が示された。従って組成比率を解析することで、IV A型とIV B型を区別することが可能である。
