Abstract
Description
本発明を説明するために使用される幾つかの用語の定義を下記に詳述する。
材料および方法
細胞培養および試薬
マウスC2C12筋芽細胞を、10%ウシ胎児血清(FBS)、50U/mLのペニシリン+50μg/mLのストレプトマイシン、および1%のL−グルタミン(Invitrogen、Milan、Italy)を追加したダルベッコ変法イーグル培地から構成される成長培地(GM)中で、空気95%/CO25%の加湿雰囲気で37℃において繁殖させた。
C2C12細胞を、24ウェルのプラスチックプレートに密度2×103細胞/cm2で播種した。塗布の1日後、その培養培地にスタチン(単独または植物性カンナビノイドの存在下で)を24時間加えた。細胞の生存を3−(4,5−ジメチルチアゾール−2−イル)−2,5−ジフェニルテトラゾリウム臭化物(MTT、5mg/mL、Sigma−Aldrich)還元アッセイにより評価し、生きている細胞のミトコンドリアによるMTT還元時のホルマザン塩の形成を分光光度法により595nmにおいて検出した。
細胞を冷PBS中で2回洗浄し、溶解溶液(150mM NaCl、1mM EDTA(pH7.4)、10mM Tris−HCl(pH8)、1%SDS、およびプロテアーゼ阻害剤)で溶解した。ライゼート(50〜60μg)をレムリSDSローディングバッファー中で5分間煮沸し、8%SDS−ポリアクリルアミドゲル電気泳動によって分離した。フィルターをマウス抗MyHC(1:1000希釈、Millipore)と一緒に4℃で一晩インキュベートした。
TRI−Reagent(Life Technology、Milan、Italy)を使用することによって全RNAを天然組織から単離し、製造業者の取扱説明書に従ってDNase−I(1U/μL、Sigma−Aldrich)と反応させ、次いで分光光度分析によって定量した。
この実施例では、高度に精製された植物性カンナビノイドCBD、CBDV、CBDA、THCV、およびCBGがテストされた。
データは、所与の実験数(n)の平均値±S.E.M.として表される。データセットは、適合するスチューデントのt検定を使用して、または必要に応じて一元配置分散分析、続いてニューマン・コイル検定を使用して比較された。統計的有意差は、pが<0.05である場合に受容された。
筋芽細胞分化に与える植物性カンナビノイドの潜在効果についての情報を得るために、C2C12細胞を、様々な植物性カンナビノイドの存在下または不在下のDM中において24〜48時間分化するように誘導した。
これらのデータは、植物性カンナビノイドCBD、CBDV、およびTHCVが骨格筋細胞の分化を調節し得ることを初めて示した。
材料および方法
細胞培養および試薬
初代ヒト衛星細胞(SC)をInnoprot Inc(Bizkaia−Spain)から購入し、必須および非必須アミノ酸、ビタミン類、有機および無機成分、ホルモン類、成長因子、微量元素、および低濃度のウシ胎児血清(5%)を含有する成長培地(GM)(Innoprot Inc/Bizkaia−Spain)中で、空気95%/CO25%の加湿雰囲気において37℃で繁殖させた。
実施例1で述べたものと同様である。
この実施例では、高度に精製された植物性カンナビノイドCBD、CBDV、およびTHCVがテストされた。
実施例1で述べたものと同様である。
ヒト骨格筋前駆細胞の分化に与えるカンナビノイドCBD、CBDV、およびTHCVの効果を更に調べるためにqPCR分析が使用された。
データは、CBD、CBDV、またはTHCVへの暴露が前駆細胞の筋管への分化を増進させるのに貢献することを示す。
材料および方法
動物:
mdxマウスを英国内務省規則(Home Office regulations)に従って飼育し保管した。6週齢の時点で雌性mdxマウスのグループ(対照はn=18、デフラザコートはn=18、CBDはn=19)を、飲料水に溶かした3.5%Kolliphor/水(v/v)に順応させた。
4週目に腓腹筋を回収し、相対的な遺伝子発現を測定した。
4週目に脾臓を回収し、CD8陽性細胞を分析した。
図7は、この検討の16週間にわたるマウスの体重を詳述する。図に見られるようにビヒクルグループとCBDグループとの間の総体質量は4週目まで差がなかったが、デフラザコートグループは有意に軽くなった(8.9%、p<0.05)。
上記in vivoのデータは、CBDがDMDを治療し得ることを実証する。
