乳腺癌组织CD44v6和nm23H1的mRNA表达及意义

目的 探讨CD44v6和nm23H1的mRNA表达与乳腺癌临床病理参数及预后的关系及相关性。方法 应用原位杂交和CSA免疫组化方法，对94例乳腺癌组织进行CD44v6和nm23H1的mRNA检测。结果 CD44v6mRNA阳性表达及nm23H1mRNA阴性表达均与乳腺癌的组织学分级、临床分期、淋巴结转移、复发和预后呈正相关。乳腺癌中CD44v6mRNA表达与nm23H1mRNA表达呈负相关。CD44v6 mRNA阳性表达及nm23H1 mRNA阴性表达患者淋巴结转移率高、生存率低。结论 CD44v6mRNA表达与nm23H1 mRNA表达具有负调节的协同作用。联合检测两种基因，能更准确地判断乳腺癌的转移、预后状态。

EXPRESSION OF mRNA OF CD44v6 AND nm23H1 IN BREAST CANCER AND THEIR SIGNIFICANCE

Objective To study the relationship of the expression of CD44v6 mRNA and nm23H1 mRNA with the clinical pathology parameter and prognosis of breast cancer, and to investigate the correlation of the expression of CD44v6 mRNA and nm23H1 mRNA. Methods In situ hybridization and CSA immunohistochemistry method were used to detect the expression of CD44v6 mRNA and nm23H1 mRNA in 94 cases of breast cancer. Results The positive expression of CD44v6 mRNA and the negative expression of nm23H1 mRNA were positively correlated with the grading, clinical stage, lymph node metastasis, and recurrence and prognosis of breast cancer. CD44v6 mRNA expression and nm23H1 mRNA were negatively correlated in breast cancer. Patients who had positive expression of CD44v6 mRNA and negative expression of nm23H1 mRNA had a higher lymph node metastatic rate and a lower survival rate. Conclusion Several genes were involved in the occurrence and development of breast cancer in which the expression of CD44v6 mRNA has synergistic action in negative regulation with that of nm23H1 mRNA. Combined detection of the expression of these two mRNA is helpful to judge the metastasis, recurrence and prognosis of breast cancer.
