高迁移率族蛋白1mRNA表达与子宫内膜癌临床病理特征的关系

目的通过检测高迁移率族蛋白1（High mobility group protein1，HMGB1）mRNA在子宫内膜癌中的表达，探讨HMGBI基因与子宫内膜癌临床病理特征的关系。方法应用半定量RT—PCR技术检测56例子宫内膜癌和20例正常子宫内膜中HMGB1 mRNA的表达情况。结果子宫内膜癌组织和正常子宫内膜组织HMGB1 mRNA的表达水平分别为0．3512±0．0985和0．2208±0．0170，内膜癌组高于正常内膜组，差异有统计学意义（P〈0．05）；子宫内膜癌按不同的临床病理特征分组，HMGB1 mRNA表达的相对含量随手术病理分期的增加、淋巴结的转移和肌层浸润的加深出现上调的趋势，差异均有统计学意义（P〈0.05）。结论HMGB1 mRNA的表达与子宫内膜癌的临床病理特征有关，HMGB1可能参与子宫内膜癌的发生、发展、浸润和转移过程。

Correlation with expression of HMGB1 mRNA and clinicopathological features of endometrial carcinoma

Objective To investigate the expression of HMGB1 mRNA in endometrial carcinoma and its correlation with clinicopathological features of endometrial carcinoma. Methods Semi-quantitative RT-PCR method was used to detect the expression level of HMGB1 gene in 56 cases of endometrial carcinoma and 20 cases of normal endometrium. Results The expression of HMGB1 mRNA in endometrial carcinoma (0. 3512 ± 0. 0985 ) was significantly higher than that in normal endometrium (0. 2208 ± 0. 0170 ).There was a significant difference in the two groups( P ＜0. 05 ). Grouping by clinicopathological features,the expression of HMGB 1 mRNA in endometrial carcinoma had a correlation with clinical-surgical stage ( P＜0. 05), metastasis of lymph nodes ( P ＜ 0. 05), and depth of myometrial invasion ( P ＜ 0. 05 ). Conclusion The high level of HMGB1 mRNA indicated that HMGB1 might play an essential role in the genesis, growth, invasion and metastasis of endometrial carcinoma.
