核因子-κB、增殖性细胞核抗原在宫颈癌组织中的表达及意义

目的探讨核因子-κB（NF-κB）、增殖性细胞核抗原（PCNA）在宫颈癌组织中的表达及其意义。方法采用免疫组织化学方法，检测45例宫颈癌组织及30例正常宫颈组织中NF—κBp65、PCNA的表达。结果宫颈癌组织中NF-κBp65、PCNA表达率均明显高于正常组织（P〈0．05）。Ⅰb、Ⅱa期宫颈癌组织NF—κBp65、PCNA表达明显高于Ⅰa期宫颈癌组织（P〈0．05），低分化者表达明显高于中、高分化者（P〈0．05），有淋巴结转移者明显高于无淋巴结转移者（P〈0．05）；且NF-κBp65与PCNA的表达呈正相关（r=0．705，P〈0．05）。结论NF-κB、PCNA与宫颈癌的发病、侵袭和转移密切相关。

Expression and significance of nuclear factor-kappa B and proliferating cell nuclear antigen in uterine cervix cancer tissues

Objective To study the expression and significance of nuclear factor-kappa B(NF-κB)and proliferating cell nuclear antigen(PCNA)in uterine cervix cancer tissues.Methods The expression of NF-κB p65 and PCNA in the uterine cervix cancer tissues(n=45)and normal cervix tissues(n=30)were detected by immunohisto chemistry method.Results The expression rate of NF-κB p65 and PCNA in the uterine cervix cancer tissues were significantly higher than that in normal cervix tissues(P＜0.05).The expression of NF-κB p65 and PCNA in stage Ⅰ b,Ⅱa were significantly higher than that in stageⅠ a(P＜0.05),they were significantly higher in poorly differentiated than those in moderately differentiated,well-differentiated(P ＜ 0.05),they were significantly higher in existing lymphnode metastasis than those in non-existing lymphnode metastasis(P ＜0.05);and the expression of NF-κB p65 was positively related to PCNA in uterine cervix cancer tissues(r=0.705,P＜0.05).Conclusion The invasion,infestation and metastasis maybe dosely related to NF-κB and PCNA.
