目的:研究半胱氨酸天冬氨酸蛋白酶招募域家族分子10(caspase recruitment domain family member 10,CARD10)在肝癌组织中的表达,及其对肝癌进展尤其是凋亡抵抗的作用和机制。方法:采集2008年至2010年海军军医大学东方肝胆外科医院收治的...目的:研究半胱氨酸天冬氨酸蛋白酶招募域家族分子10(caspase recruitment domain family member 10,CARD10)在肝癌组织中的表达,及其对肝癌进展尤其是凋亡抵抗的作用和机制。方法:采集2008年至2010年海军军医大学东方肝胆外科医院收治的129例肝癌患者手术切除的肝癌及其癌旁组织标本,采用实时定量PCR法检测癌旁和肝癌组织中CARD10的表达,以Spearman等级相关统计学分析CARD10表达与肝癌分期的相关性。在CARD10质粒转染过表达以及RNA干扰敲减表达后,采用流式细胞术Annexin-V/PI标记法检测肝癌细胞株的凋亡,采用Western blotting检测肝癌细胞株中NF-κB信号的活化。结果:CARD10在肝癌组织中的表达较癌旁组织显著增高(P<0.01),且肝癌组织中CARD10的表达增高与肝癌分期进展呈正相关(P<0.01)。CARD10过表达可以抑制肝癌细胞株SMMC-7721和BEL-7402的凋亡,而敲减CARD10能够促进肝癌细胞株凋亡。CARD10过表达能够增强肝癌细胞株中促生存的NF-κB信号的活化,而CARD10敲减能够抑制NF-κB信号活化。结论:CARD10在肝癌组织中表达显著增高并与肝癌进展呈正相关,CARD10能够通过活化NF-κB信号进而促进肝癌细胞凋亡抵抗。展开更多
