【摘要】 目的:研究表明IL-11、IL-11R与多种恶性肿瘤的生长、分化、进展密切相关。本实验采用Western blot法检测IL-11、IL-11R在原发性肝癌中的表达,探讨二者的表达与肝癌及相关临床和病理指标间的关系。方法:收集30例原发性肝癌手术患者的新鲜肿瘤组织、邻近的非癌肝组织标本及其临床、病理资料。采用Western blot法检测IL-11、IL-11R在肝癌组织、邻近的非癌肝组织中的表达。分别测定IL-11、IL-11R及β-actin带的积分光密度(IOD)值,以目的蛋白与相应β-actin的IOD值比值(A值)来表示目的蛋白的表达水平。结果:(1)IL-11在肝癌组织中表达水平(A值)(0.71±0.19),显著高于癌旁肝组织(0.34±0.27 P＜0.01),二者差异有显著性,而IL-11的表达与患者性别、诊断年龄、肿瘤大小、有无肝硬化、有无淋巴结转移均无相关性(P＞0.05),根据Edmondson病理分级分组,Ⅳ级肿瘤表达A值(0.83±0.13),明显高于Ⅰ+Ⅱ+Ⅲ级肿瘤表达A值(0.60±0.18 P＜0.05),在包膜受侵犯组肝癌中表达A值(0.89±0.10)明显高与包膜未受侵犯组(0.64±0.18 P＜0.05);在有门静脉癌栓组肝癌组中表达A值(0.83±0.13)亦明显高于无门静脉癌栓组(0.62±0.19 P＜0.05)。(2)IL-11R的肝癌组织中表达水平(A值)(0.56±0.19),显著高于癌旁肝组织(0.41±0.25 P＜0.01),二者差异有显著性,IL-11R的表达与患者性别、诊断年龄、肿瘤大小、有无肝硬化、肿瘤的分化程度均无相关性(P＞0.05),肿瘤伴有淋巴结转移组A值为(0.70±0.09),明显高于不伴淋巴结转移组(0.50±0.19 P＜0.05)。在包膜受侵犯组肝癌中表达A值(0.72±0.09)明显高与包膜未受侵犯组(0.48±0.17 P＜0.05);在有门静脉癌栓组中表达A值(0.67±0.15)亦明显高于无门静脉癌栓组(0.49±0.16 P＜0.05)。结论:(1)IL-11和IL-11R在肝癌组织及癌旁肝组织均有表达。肝癌组织中表达明显高于癌旁肝组织。提示IL-11/IL-11R可能与参与肝癌的发生。(2)IL-11的表达在分化程度低、包膜受侵犯、门静脉有癌栓组肝癌组织标本表达水平高;IL-11R的表达在有淋巴结转移、包膜受侵犯、门静脉有癌栓组肝组织标本表达水平高。表明IL-11/IL-11R可能参与肝癌的分化、侵袭及转移过程。更多还原

【Abstract】 Objectives:Previous investigations have shown that interleukin-11(IL-11)and interleukin-11 receptor(IL-11R)have been correlated with the regulation of tumor progression,cellular growth and differentiation in several malignant tumors.The objectives of this study were to clarify the role of IL-11 and IL-11R in human hepatocelluar carcinoma.Methods:30 PHC tissues,their pericarcinomatous liver tissues and their clinicopathological factors were obtained in the current study.Expression levers of IL-11 and IL-11R proteins in samples of pericarcinomatous liver and tumor tissue were analyzed by Western blot.The IOD of IL-11、IL-11R andβ-actin was quantitatively analysised by Analysis software.The expression level of IL-11 and IL-11R was denoted by the ratio of IOD,which was called value A.Results:(1)The value A of IL-11 in PHC tissue is 0.71±0.19,which sharply higher than that in pericarcinomatous liver tissue(0.34±0.27 P＜0.01),The expression of IL-11 has nothing to do with gender,age,size of tumor,corrhosis and lymph node metastasis.There is significance difference between the expression of IL-11 in gradeⅣ(0.83±0.13)and gradeⅠ+Ⅱ+Ⅲ(0.60±0.18)according to Edmondson’s grad(P＜0.05).Also the expression of IL-11 is significantly related to capsule invasion(capsule invasion 0.89±0.10 non-capsule invasion 0.64±0.18 P＜0.05)and tumor’s thrombus in portal vein(tumor’s thrombus in portal vein 0.83±0.13 No tumor’s thrombus in portal vein 0.62±0.19 P＜0.05)(2)The value A.of IL-11R in PHC tissue is 0.56±0.19,which remarkable higher than that in pericacinomatous liver tissue(0.41±0.25 P＜0.01).The expression of IL-11R have no relationship with gender,age,size of tumor,cirrhosis and differentiation grade of tumor.But there is statistical difference between the expression of IL-11R in tumor with lymph node metastasis(0.70±0.09)and tumor without lymph node metastasis(0.50±0.19 P＜0.05).Also the expression of IL-11R is significantly related to capsule invasion(capsule invasion 0.72±0.09 non- capsule invasion 0.48±0.17 P＜0.05)and tumor’s thrombus in portal vein(tumor’s thrombus in portal vein 0.67±0.15 No tumor’s thrombus in portal vein 0.49±0.16 P＜0.05)Conclusion:(1)The expression of IL-11 and IL-11R is upregulated obviously in PHC tissue,which indicate that IL-11/IL-11R may be concerned with the occurrence of PHC.(2)IL-11’s expression is markly higher in Edmonson gradingⅣ, capsule invasion,tumor’s thrombus in portal vein group than that in Edmonson gradingⅠ+Ⅱ+Ⅲ,non-capsule invasion,No tumor’s thrombus in portal vein group.IL-11R’s expression is obviously higher in lymph node metastasis,capsule invasion,tumor’s thrombus in portal vein group than that in non-metastasis non-capsule invasion,No tumor’s thrombus in portal vein group.These findings suggest that IL-11/IL-11R pathway may play important role in the differentiation,invasion and transfer of PHC.更多还原
