文题释义:
细胞迁移:
也称为细胞爬行、细胞移动或细胞运动,是指细胞在接收到迁移信号或感受到某些物质的梯度后而产生的移动。细胞迁移为细胞头部伪足的延伸、新的黏附建立、细胞体尾部收缩在时空上的交替过程。细胞迁移是正常细胞的基本功能之一,是机体正常生长发育的生理过程,也是活细胞普遍存在的一种运动形式。胚胎发育、血管生成、伤口愈合、免疫反应、炎症反应、动脉粥样硬化、癌症转移等过程中都涉及细胞迁移。
细胞骨架:20世纪60年代后,人们使用戊二醛常温固定的方法开始逐渐发现细胞骨架。科学家发现,细胞骨架在细胞迁移过程起到承载和支撑的作用。在20世纪末21世纪初,科学家对细胞迁移复杂机制的认识有了非常大的进步,对细胞与基质的粘着、非对称性极化和胞内分层运动都有了进一步的了解、但是整个过程其实仍未被了解透彻,很多中间过程就是连起作用的物质都未明。科学家对其中部分需要进行假设,再进一步通过实验去证实。

 

摘要
背景:
在类风湿关节炎的发病过程中,其滑膜衬里层的成纤维样滑膜细胞的病理生理学行为涉及细胞的增殖、侵袭、迁移、凋亡和破骨作用。
目的:比较类风湿关节炎关节成纤维样滑膜细胞(MH7A)与正常关节成纤维样滑膜细胞(HFLS)迁移和侵袭能力。  
方法:利用Transwell细胞迁移和侵袭实验比较2种细胞的迁移、侵袭能力,设计11种miRNA序列特异性引物,按SYBR®PrimeScript™miRNA RT-PCR Kit说明书进行实时定量聚合酶链式反应检测类风湿关节炎相关miRNAs的表达。
结果与结论:①Transwell细胞迁移、侵袭实验显示MH7A迁移和袭能力较HFLS明显增强;与HFLS相比,MH7A细胞中miR-132、-155、-203、-223、-124的表达上调;而miR-15a、-16、18a、-19a、-26a、-146a的表达下调。②结果说明,MH7A迁移和侵袭能力较HFLS明显增强;与HFLS相比,MH7A中类风湿关节炎相关的11种miRNAs表达水平的改变,可能通过相应的机制调节类风湿关节炎成纤维样滑膜细胞的迁移和侵袭,参与类风湿关节炎的发病。

Abstract:

BACKGROUND: Fibroblast-like synoviocytes (FLS) in the synovial lining layer are related to the cell proliferation, invasion, migration and apoptosis as well as bone resorption in rheumatoid arthritis.

OBJECTIVE: To compare the migration and invasion abilities of FLS (MH7A) in rheumatoid arthritis and normal FLS (HFLS).
METHODS: The capacities of cell migration and invasion were evaluated by Transwell cell migration and invasion assays. The primers of the indicated microRNAs were designed and synthesized, and the expression levels of miRNAs were determined by real-time PCR according to the SYBR®PrimeScript™miRNA RT-PCR Kit instruction.

RESULTS AND CONCLUSION: MH7A possessed stronger migration and invasion abilities than HFLS. Compared with HFLS, obviously upregulated miR-132, -155, -203, -223 and -124, and significantly downregulated miR-15a, -16, 18a, -19a, -26a and -146a were found in MH7A. These findings suggest that the differentially expressed 11 kinds of rheumatoid arthritis-associated miRNAs participate in the pathogenesis of rheumatoid arthritis probably by enhancing the migration and invasion capacities of MH7A.
