摘要:

目的:研究转录因子Oct-4和SOX-2在宫颈癌及正常宫颈组织中的表达情况,
阐明二者作为宫颈癌干细胞标记物的可能性。方法:采用免疫组织化学SP法检测Oct-4和SOX-2在
52例宫颈癌组织和28例正常宫颈组织中的表达,分析二者在不同类型宫颈癌患者中的表达情况。
结果:Oct-4在宫颈癌组织中表达率(46.1%,24/52)显著高于其在正常组织中的表达率(7.1%,2/28),二者比较差异有统计学意义(P<0.05);SOX-2
在宫颈癌组织中的表达率(59.6%,31/52)显著高于其在正常组织中的表达率(10.7%,3/28),
二者比较差异有统计学意义(P<0.05)。宫颈癌组织中Oct-4和SOX-2的表达与患者年龄、病
理类型和FIGO分期均无关联性(P>0.05);与宫颈癌的分化程度有关联,随分化程度的降低,Oct-4和SO
X-2表达水平升高,不同分化程度宫颈癌患者表达频数比较差异均有统计学意义(P<0.05);宫颈癌组织中Oct-4与SOX-2的表达频数呈正相关关系(r=0.753,P<0.05)。结论:Oct-4和SOX-2在宫颈癌组织中频数较高,且随宫颈癌分化程度降低表达频数升高,提示Oct-4和SOX-2可作为
宫颈癌干细胞的标记物。

Abstract:

Objective To investigate the expressions of transcription factor Oct-4
 and SOX-2 in cervical cancer and normal cervix  tissue and to explore the possibility of Oct-4 and SOX-2 as the  stem cell markers of cervical cancer.
Methods The expressions of Oct-4 and SOX-2  in 52 cases of cervical cancer tissue and 28 cases of normal cervix tissue
 were detected by immunohistochemical SP   method.The expressions of Oct-4 and SOX-2 in the patients with cervical canc
er with different types were analyzed.Results The expression of Oct-4 protein in cervical cancer tissue(46.1%,24/5
2) was significantly higher than that in normal cervix tissue(7.1%,2/28)(P<0.05);the expression of SOX-2 protein in cervical  cancer tissue(59.6%,31/5
2) was significantly higher than that in normal cervix tissue(10.7%,3/28)(P<0.05).The expressions of Oct-4 and SOX-2 in cervical cancer tissue  were significantly correlated with the histological grade(P<0.05);but not correlated with the age,pathological type,FIGO stage of the patients(P>0.05).The expressions of OCt-4 and SOX-2 were increased with the decreasing of the differentiation degree,and there were significant differences of the expression frequencies  of OCt-4 and SOX-2 in the patients with different differentiation degrees(P<0.05).The expression of Oct-4 was positively related to the expression of SOX-2 in cervical cancer tissue(P<0.05).
Conclusion The expression frequencies of Oct-4 and SOX-2 in cervical cancer tissue are increased with the decreasing of differentiantion degree of cervical cancer which indicates that Oct-4 and SOX-2 may be used as the markers of cervical cancer stem cells.
