摘要:
 【摘要】 目的 探讨高迁移率族蛋白B1( high mobility group protein B1,HMGB1)对激素难治性前列腺癌冷冻免疫反应的影响。方法 复制RM?蛳 1细胞激素非依赖性前列腺癌模型,将50只小鼠随机分为对照组(n = 25)和冷冻消融治疗组(n = 25)。利用氩氦冷冻系统针式冷冻器行皮下移植瘤冷冻消融治疗。分别于冷冻消融治疗前、治疗后1、7、14、21 d应用Western印迹技术检测HMGB1蛋白在肿瘤局部的表达情况,应用流式细胞术检测肿瘤局部树突状细胞(DC)的数量及活化比例。结果 治疗组肿瘤局部HMGB1表达水平及DC数量及活化比例均于术后第7天达最高值,与术前相比差异有统计学意义(P < 0.05);对照组HMGB1表达水平及DC数量及活化比例无明显改变,组内比较差异无统计学意义(P > 0.05)。治疗组术后1、7、14 d,肿瘤局部HMGB1表达水平及DC数量及活化比例均高于对照组,组间差异有统计学意义(P < 0.05)。相关性分析显示,治疗组肿瘤局部HMGB1表达量与DC数量、DC活化比例均呈高度正相关(r = 0.883,r = 0.997,P < 0.05)。结论 冷冻消融治疗导致肿瘤细胞坏死的同时可释放大量HMGB1,这些释放至细胞外的HMGB1在冷冻消融治疗后刺激机体产生特异性抗肿瘤冷冻免疫反应中发挥重要作用。
