Description
2.奇数脂肪酸が、C3プロピオン酸、C5吉草酸、C7エナント酸、C9ペラルゴン酸、C11ウンデカン酸、C13トリデカン酸、C15ペンタデカン酸、C17マルガリン酸、C19ノナデカン酸、C21ヘンイコシル酸、C23トリコシル酸からなる群から選択される、項目1に記載の細胞増殖促進剤。
3.高度不飽和脂肪酸が、ω-3脂肪酸である、項目1又は2のいずれか1項に記載の細胞増殖促進剤。
4.奇数脂肪酸又は高度不飽和脂肪酸が生物由来の天然に存在するものである、項目1〜3のいずれか1項に記載の細胞増殖促進剤。
5.奇数脂肪酸及び高度不飽和脂肪酸がオーランチオキトリウム(Aurantiochytrium)属藻類由来である、項目1〜4のいずれか1項に記載の細胞増殖促進剤。
6.奇数脂肪酸及び高度不飽和脂肪酸が、同一の、又は個別のトリグリセリドとのエステルの形態で存在する、項目1〜5のいずれか1項に記載の細胞増殖促進剤。
7.オーランチオキトリウム属藻類から抽出された奇数脂肪酸及び高度不飽和脂肪酸を含有するトリグリセリドを有効成分として含有する細胞増殖促進剤。
8.オーランチオキトリウム属藻類細胞を有効成分として含有する細胞増殖促進剤。
9.奇数脂肪酸と高度不飽和脂肪酸を、脂肪酸の重量比にして20:1〜1:20、18:1〜1:18、16:1〜1:16、14:1〜1:14、12:1〜1:12、10:1〜1:10、8:1〜1:8、6:1〜1:6、4:1〜1:4、又は2:1〜1:1で含有する、項目1〜8のいずれか1項に記載の細胞増殖促進剤。
10.損傷した組織の治癒、疼痛、自己免疫性疾患、神経変性疾患、免疫性疾患、代謝性症候群に関連する疾患及び癌関連疾患の緩和、皮膚の皺の減少、皮膚の代謝促進、育毛、アレルギー症状の軽減、筋肉痛の軽減、又は運動機能の向上のために用いられる、項目1〜9に記載の細胞増殖促進剤。
オーランチキトリウム属藻類NB6−3株(沖縄、オーピーバイオファクトリー株式会社)を、250mlのGTY培地(1%トリプトン、2%グルコース、0.5%酵母エキス、1.0%海水塩)を用いて、500mlの坂口培養フラスコの中で、一定温度、25℃、100ストローク/分で培養を行った。これを2,500g×で15分間遠心分離して12時間ごとに回収し、1.5%海水塩溶液で2回洗浄した。得られた細胞塊を、凍結乾燥させた。細胞量は、凍結乾燥させた細胞を計量して求めた。
対数増殖期のC15およびDHAの増加と細胞増殖の関係を明らかにするために、脂肪酸混合物を含む増殖培地の中で、オーランチオキトリウム属藻類NB6−3を増殖させた。DHA(50 mg/mL、東京化成工業製)とC15ペンタデカン酸(東京化成工業製)またはC14ミリスチン酸(和光純薬製)(25 mg/mL)の混合物を、50% DMSOで乳化した。同様に、オレイン酸(C18=1、50 mg/mL) と、C15またはC14(25 mg/mL)の混合物を50% DMSOで乳化した。これらの乳化液を、それぞれ培養液 (GTY培地(1%トリプトン、2%グルコース、0.5%酵母エキス、1.0%海水塩))で10倍に希釈し、当該希釈乳化液10μLを、オーランチオキトリウム属藻類NB6−3の培養物100μL(1×105細胞)に添加して、96穴のプレートで25℃、24時間培養後、培養物中の細胞の濃度を定量するため、分光光度計で濁度(OD650nm)を測定した。脂肪酸混合物の最終濃度は、75μg/100μLとなる。24時間培養後の濁度から培養液開始時の濁度を差し引いた値を、細胞増殖量とした。
オーランチオキトリウムNB6−3の細胞増殖に対する脂肪酸混合物の効果
実施例2において示された脂肪酸混合物のオーランチオキトリウム属藻類NB6−3に対する増殖促進効果が哺乳類細胞でも観察されるか否かを調査するために、脂肪酸混合物を含む増殖培地の中で、マウス胎児由来繊維芽細胞BalB/3T3 (Cell No. RCB0005、理化学研究所)を増殖させた。
