We investigated the effects of celecoxib combined with (-)-epigallocatechin-3-gallate (EGCG) or polyphenon E in a cisplatin-induced lung tumorigenesis model. Four-week-old female A/J mice were divided into seven groups: (i) Control, (ii) 150 mg/kg celecoxib (150Cel), (iii) 1,500 mg/kg celecoxib (1500Cel), (iv) EGCG+150 mg/kg celecoxib (EGCG+150Cel), (v) EGCG+1,500 mg/kg celecoxib (EGCG+1500Cel), (vi) polyphenon E+150 mg/kg celecoxib (PolyE+150Cel), and (vii) polyphenon E+1,500 mg/kg celecoxib (PolyE+1500Cel). All mice were administered cisplatin (1.62 mg/kg of body weight, i.p.) 1×/week for 10 weeks and sacrificed at week 30; the numbers of tumors on the lung surface were then determined. The tumor incidence and multiplicity (no. of tumors/mouse, mean±SD) were respectively 95% and 2.15±1.50 in Control, 95% and 2.10±1.29 in 150Cel, 86% and 1.67±1.20 in 1500Cel, 71% and 1.38±1.24 in EGCG+150Cel, 67% and 1.29±1.38 in EGCG+1500Cel, 80% and 1.95±1.36 in PolyE+150Cel, and 65% and 1.05±0.10 in PolyE+1500Cel. The combination of high-dose celecoxib with EGCG or polyphenon E significantly reduced multiplicity in cisplatin-induced lung tumors.
我们在顺铂诱导的肺癌发生模型中研究了塞来昔布联合(-)-表没食子儿茶素-3-没食子酸酯(EGCG)或多酚 E 的效果。将 4 周龄雌性 A/J 小鼠分为 7 组:(i)对照组,(ii)150mg/kg 塞来昔布(150Cel),(iii)1500mg/kg 塞来昔布(1500Cel),(iv)EGCG+150mg/kg 塞来昔布(EGCG+150Cel),(v)EGCG+1500mg/kg 塞来昔布(EGCG+1500Cel),(vi)多酚 E+150mg/kg 塞来昔布(PolyE+150Cel),和(vii)多酚 E+1500mg/kg 塞来昔布(PolyE+1500Cel)。所有小鼠每周接受 1 次顺铂(1.62mg/kg 体重,腹腔内注射)10 周,并在第 30 周处死;然后确定肺表面肿瘤的数量。对照组的肿瘤发生率和多发性(肿瘤数/只,平均值±标准差)分别为 95%和 2.15±1.50,150Cel 组为 95%和 2.10±1.29,1500Cel 组为 86%和 1.67±1.20,EGCG+150Cel 组为 71%和 1.38±1.24,EGCG+1500Cel 组为 67%和 1.29±1.38,PolyE+150Cel 组为 80%和 1.95±1.36,PolyE+1500Cel 组为 65%和 1.05±0.10。高剂量塞来昔布与 EGCG 或多酚 E 的联合使用显著降低了顺铂诱导的肺癌肿瘤的多发性。
