Description
1)対数増殖期にあるPC−3細胞を採取して単一細胞懸濁液を調製した。1ウェルあたり100μlの細胞懸濁液(1×104細胞を含む)を96ウェルプレート内に播種し、5つの群:溶媒対照群、10μM群、50μM群、100μM群、200μM群に分けた。それぞれの群は、6つの複製物を含む。細胞を(37℃、5%CO2において)24時間プレインキュベートした;
2)新しい培地を使用し、異なる濃度のZL−n−91をそれぞれの群に添加した。細胞を(37℃、5%CO2において)それぞれ24時間および48時間継続して培養した;
3)100μlの10%CCK−8溶液を各ウェルに気泡なく添加した;
4)細胞を1〜2時間インキュベートし、プレートをそれぞれ30分、60分、および90分で取り出した。マイクロプレートリーダーを使用して、450nmにおける吸光度を測定した。
1)対数増殖期にあるPC−3細胞を採取して無血清F−12K培地中に単一細胞懸濁液を調製し、1.5mlのEPチューブに120μlずつ分注した(2×106細胞を含む);
2)調製した細胞懸濁液のうちの0.1mlを1mlの滅菌シリンジでヌードマウス内に皮下接種した;
3)接種3日後にマウスを薬物治療した。
4)ヌードマウスを2つの群:溶媒対照群および投与群(10mg/kg)に分けた。マウスに毎日投薬した。マウスの腫瘍体積および体重を週2回測定した;
5)腫瘍体積が1500mm3に到達したとき、腫瘍を摘出した。腫瘍サイズを測定し、腫瘍重量を記録した。
切除した腫瘍を4%ホルマリン中で一晩固定し、切片化のためにパラフィン中に包埋した。次いで、腫瘍増殖抗原Ki67を染色した。
1)対数増殖期にある細胞を採取して無血清DMEM培地中に懸濁液を調製した。1ウェルあたり100μlの細胞懸濁液(5×104細胞を含む)をTranswellの上方のチャンバーに添加した。それを3つの群:溶媒対照群、10μM群、50μM群に分けた。それぞれの群は、3つの複製を含む。
2)10%のFBSを含む完全DMEM培地を12ウェルプレートの下方のチャンバーに添加した。
3)12時間後、上方のチャンバーを取り出し、氷冷メタノール中で30分間固定し、室温で自然乾燥させた。
4)600μlの0.1%クリスタルバイオレット溶液を12ウェルプレートに添加し、チャンバーの下の表面にある細胞を15分間染色した。
5)PBSをチャンバーに添加し、次いで、5分後にそのPBSをピペットで取り出した。メンブレンの上部からの細胞をきれいな綿棒で優しく拭き取った。チャンバーをPBSで3回洗浄し、次いで、室温で自然乾燥させた。
6)300μlの10%酢酸溶液を12ウェルプレートに添加し、チャンバーの下の表面を10分間浸漬して細胞内のクリスタルバイオレット粒子を溶解させた。
7)12ウェルプレートの各ウェルからの100μlの溶液を96ウェルプレートに入れ、マイクロプレートリーダーを使用して570nmにおける吸光度を測定した。
