To explore the relationship between c-myc and bcat1 expression and the occurrence, development and clinical features of cervical cancer.
The expression level of c-myc and bcat1 were detected in 30 cases of normal cervical tissues, 30 cases of CIN tissues, 40 cases of cervical squamous carcinoma tissues and 40 cases of cervical adenocarcinoma tissues by immunohistochemistry; Conduct a Spearman rank correlation analysis between c-myc and bcat1 expressions; Analyze the relationship between the expression of both genes and clinicopathological factors of cervical cancer.
The positive rates of c-myc expression were 16.7% (5/30) in normal cervical tissues, 43.3% (13/30) in CIN tissues and 73.8% (59/80) in cervical cancer tissues, the positive rates of bcat1 expression were 10.0% (3/30) in normal cervical tissues, 23.3% (7/30) in CIN tissues and 52.5% (42/80) in cervical cancer tissues. The rank correlation index between c-myc and bcat1 is respectively 0.773 (=0.000) in cervical squamous carcinoma and 0.369 (=0.019) in adenocarcinoma. The positive expression rate of c-myc was related to the pathological type of cancer tissue (adenocarcinoma/squamous cell carcinoma), the degree of tumor tissue differentiation, the depth of interstitial infiltration, and the presence or absence of vascular invasion (<0.05). The positive expression rate of bcat1 was related to the degree of tumor differentiation, vascular invasion and Ki67 index (<0.05).
The high expression of c-myc may promote the invasion and metastasis of cervical cancer, and the high expression of bcat1 may promote the proliferation, invasion and metastasis of cervical cancer, which may have a synergistic effect in the pathogenesis of cervical cancer.
探讨c-myc和bcat1表达与宫颈癌发生、发展及临床特征的关系。
采用免疫组织化学法检测30例正常宫颈组织、30例宫颈上皮内瘤变(CIN)组织、40例宫颈鳞癌组织及40例宫颈腺癌组织中c-myc和bcat1的表达水平;对c-myc与bcat1表达进行Spearman等级相关分析;分析两者基因表达与宫颈癌临床病理因素的关系。
c-myc表达阳性率在正常宫颈组织中为16.7%(5/30),CIN组织中为43.3%(13/30),宫颈癌组织中为73.8%(59/80);bcat1表达阳性率在正常宫颈组织中为10.0%(3/30),CIN组织中为23.3%(7/30),宫颈癌组织中为52.5%(42/80)。c-myc与bcat1在宫颈鳞癌中的等级相关指数分别为0.773(P=0.000),在腺癌中为0.369(P=0.019)。c-myc阳性表达率与癌组织病理类型(腺癌/鳞癌)、肿瘤组织分化程度、间质浸润深度及有无血管浸润有关(P<0.05)。bcat1阳性表达率与肿瘤分化程度、血管浸润及Ki67指数有关(P<0.05)。
c-myc高表达可能促进宫颈癌的侵袭和转移,bcat1高表达可能促进宫颈癌的增殖、侵袭和转移,二者在宫颈癌发病机制中可能具有协同作用。
