乳腺癌恶化的肿瘤标志物CYR61 检测试剂盒 CYR61 是诊断 / 判断乳腺癌恶化的肿瘤标志物。 富含胱氨酸蛋白质 61 是分子量为 50KD 的糖蛋白,可调节血管上皮细胞,纤维母细胞和单核细胞的增生与粘附。 CYR61 是 CCN 家族中(包括: CCN1=CYR61,CCN2=CTGF,CCN3=NOV,CCN4=Wisp-1,CCN5=Wisp-2,CCN6=Wisp-3 )*个被克隆的成员。 CYR61 在 VWF 位点被纤维酶降解后,产生能够诱发上皮细胞迁移的 N 末端片段。 CYR61 在血管重建,上调 VEGF 的作用,以及骨形成过程中起到关键作用。 CYR61 的超量表达往往预示着乳腺癌的恶化( 1 , 3 ),腺癌的病理改变( 2 ),以及胰腺癌( 4 )和胶质瘤( 5 )的产生。 CYR61 同时也可以作为妊娠先兆子痫的早期诊断标志物( 6 )。 DRG 公司以固相三明治酶联免疫( ELISA )检测法开发生产了 CYR61ELISA 检测试剂。 参考文献 • Sampath D, Winneker HC,and Zhang Z CYR61,a member of the CCN family,is required for MCF-7 cell proliferation regulation by 17b-Estradiol and overexpression in human breast canner,Endocrinilogy 2001;142(6)2540-8 • Ming-Tsai,Chung-Yaou Zuon,Cheng-chi Chang,Szu-Ta Chen,Been-Ren Lin,Ming-Yangwang,Yung-MingJeng,King-Jen Chang,Po-Huang Lee,Wei-Jao Chen,and Min-Liang Kuo.CUR61 Induces Gasteric Cancer CellMotilityInvasion via Activation of the Integrin/Nuclear Factor KB/Cyclooxygenase-2 Signaling Pathway.Clin Cancer Res.2005;11(16)5809-20 • JA Menendez I Mehmi,D W C Griggs1 and R Lupu.The angiogenic factor CYR61 in breast cancer Molecular pathology and therapeutic perspectives.Endorcrine-Related Cancer 2003;10 141-152 • Holloway SE,Beck AW,Griard L.Jaber MR,Barnett SS Jr,Brekken RA,Fleming JB,Increased expression of Cyr61(CCN1)identified in peritoneal metastases from human pancreatic cancer J Am Coll Surg.2005;200(3);371-7 • Xie D,Yin D,Wang HJ,Liu GT,Elashoff R,Black K,Koeffler HP,Levels of CYR61 and CTGF are prognostic for tumor progression and survival of individuals with gliomas Clin Cancer Res,2004;10(6);2072-81 • Alexandra Gekkhaus,Msrkus Schmidt,Caroline Dunk,Stephen,J,lye,Rainer Kimming and Elke Winlterhager,Decreased expression of the angiogenic regulatoys CYR61(CCN1) and NOV(CNN3) in human placenta is associated with pre-eclampsia.Molecular Human Reproduction 2006;12,(6)389-399 |
