文题释义:
Mkx(Mohawk):又被称为Irxl,是三氨基环酸超家族的成员之一。Mkx是肌腱发育过程中肌腱细胞所表达的非典型的同源异型盒基因,在许多组织器官发育过程中都是必要的,包括细胞的增殖、分化等过程。Mkx具有转录抑制活性,且包括了3个小阻遏域。Mkx作为一个转录抑制因子,是通过招募Sin3A / DHAC抑制复合物而发挥作用的。
掌板:也叫掌侧韧带,为一长方形的致密纤维软骨板,位于掌指关节及指间关节掌侧。其中掌指关节掌板其远端厚而坚韧,附于近节指骨底掌唇,近端薄而松弛,呈膜状附于掌骨颈掌侧,并与深筋膜交织,两侧与侧副韧带相连。远侧指间关节的掌板为远侧指间关节掌侧一长方形质地坚韧的致密纤维软骨扳,远端厚而坚韧。坚固地附于远节指骨底掌倒唇,构成关节囊的掌面,同时也构成屈肌腱的底面,近端薄而松弛为膜样结构,并与骨膜相延续。
摘要
背景:
近年来研究证实转录因子Mkx(Mohawk)是肌腱形成、发育、分化的关键因子之一。
目的:总结Mkx的分子结构、分布、功能以及在肌腱分化过程中的信号通路等方面的研究进展。
方法:用计算机检索维普数据库(1990至2016年)、中国期刊全文数据库(1990至2016年)及Medline数据库(1990至2016年),检索词分别为“Mkx;Mohawk;Irxl;肌腱;成肌腱分化;组织工程;转化生长因子β;干细胞;和“Mkx;Mohawk;Irxl;tendon;tendon differentiation;tissue engineering;TGFβ;stem cell”。检索有关转录因子Mkx(Mohawk)在肌腱组织工程中的研究进展,最终保留55篇文献。 
结果与结论:转录因子Mkx在肌腱形成发育及组织工程肌腱的形成过程中发挥重要作用。Mkx在多种中胚层来源组织细胞中表达,Mkx发挥作用的途径虽不直接作用于Scx(Scleraxis),但可间接调控转化生长因子β2信号通路来调控肌腱祖细胞的分化,而干细胞的物种来源和不同细胞系以及不同细胞因子均对Mkx在肌腱组织工程中发挥作用有不同的影响。

Abstract:

BACKGROUND: Mkx (Mohawk, transcription factor) is one of the crucial factors in tendon formation, development and differentiation.
OBJECTIVE: To summarize the molecular structure, distribution and function of Mkx and its research process in the signaling pathways during tendon differentiation.
METHODS: The first author retrieved the databases of CqVip, CNKI and Medline from1990 to 2016 using the keywords of “Mkx, Mohawk, Irxl, tendon, tendon differentiation, tissue engineering, TGFβ, stem cell” in Chinese and English, respectively. The articles related to research process of Mkx in tendon tissue engineering were retrieved, and a total of 55 literatures were enrolled finally.
RESULTS AND CONCLUSION: Mkx that expresses in various mesoderm-derived tissues plays an important role in the formation and development of tendon and tissue-engineered tendon formation. Although Mkx does not directly act on Scx (Scleraxis), it can regulate the differentiation of tendon progenitor cells via transforming growth factor-β2 signaling pathway. Cells from different species and different cell lines as well as various cytokines for certain make different effects on Mkx involved in tendon tissue engineering.
