摘要 目的:探讨耐力运动对雌激素依赖性乳腺癌肿瘤血管生成的影响。方法:40只雌性BALB/c小鼠随机分为2组,一组小鼠在跑台上进行8周持续耐力运动,另一组不进行运动。之后给予2组小鼠注射雌激素依赖性MC4L2癌细胞,肿瘤形成后,随机再将这两组小鼠以每组10只,分为4组,即:运动-肿瘤-运动组(A);运动-肿瘤-休息组(B);休息-肿瘤-运动组(C)和休息-肿瘤-休息组(D)。A、C组小鼠进行为期6周的耐力运动,每周运动5天。期间,每周测量肿瘤体积。最后,处死小鼠,摘除肿瘤组织,制成匀浆ELISA定量法测量细胞因子白细胞介素-6(IL-6)和血管内皮生长因子(VEGF)的表达水平。结果:A、C组与B、D组相比,IL-6(P=0.001)、VEGF(P=0.0001)和肿瘤体积(P=0.0001)显著降低。结论:运动可致使乳腺癌细胞致瘤小鼠的肿瘤组织内促炎症细胞因子水平降低,抑制肿瘤血管生成因子表达增加。因此,运动对雌激素依赖的乳腺癌可能有一定的辅助治疗与预防作用。
