概括

蛋白Z (PZ) 促进了肺癌的转移. 击败PZ减少了癌细胞的增殖,迁移和入侵,这表明PZ是非小细胞肺癌的潜在治疗标.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
生物化学生物化学

背景情况:

蛋白Z (PZ) 是一种依赖维生素K的抗凝血糖蛋白,在恶性组织中表达高.
增加PZ表达与肺癌患者的预后不佳相关.

研究的目的:

研究蛋白Z (PZ) 在肺癌细胞迁移,入侵和转移中的病理作用.
探索PZ对非小细胞肺癌 (NSCLC) 中表皮细胞-介质细胞转换 (EMT) 途径的影响.

主要方法:

西方斑块被用来评估NSCLC细胞系中的PZ表达 (A549,H1299,H1975).
siRNA被用来在A549细胞中击倒PZ.
进行细胞计数套件 (CCK) -8,伤口愈合和Transwell测试以评估扩散,迁移和入侵.
西方斑点被用来检测PZ淘汰后的EMT标记物 (Slug,Vimentin,N-cadherin).

主要成果:

证实PZ表达在A549,H1299和H1975NSCLC细胞系中升高.
抑制PZ显著抑制了A549细胞的增殖,迁移和入侵.
PZ的淘汰导致EMT标记物的蛋白质水平降低: Slug,Vimentin和N-cadherin.

结论:

蛋白Z (PZ) 在肺癌中表现出前转移活性.
在A549肺癌细胞中,PZ调节了表皮层-介质细胞过渡 (EMT) 途径.
向PZ可能代表NSCLC治疗的新疗法策略.

关键词:

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
