文题释义:
TGF-β/Smad3信号通路:
无活性的TGF-β经水解后获得活性并与TβRII相结合,其配体复合物可激活TPRI的丝氨酸/苏氨酸激酶磷酸化而表现出激酶活性;活化的TβRI激酶区的IV和V亚区的L45环结构特异性结合胞内R-Smads的MH2区L3环结构,在R-Smads端的SSXS基序的2个丝氨酸残基被磷酸化后,MH1与MH2区相互接触的状态接触,分子完全伸展,使R-Smad呈活化构象。
干扰素:是由某些细胞受到一定的反应刺激而产生分泌的一类蛋白质,依据其分子结构与抗原性的不同,将其分为α、β和γ 3种类型。人的IFN γ基因定位于第12对染色体长臂,长度约为6 kb,相对分子质量为40 000,由3个内含子和4个外显子构成,成熟IFN -Y因子由143个氨基酸组成。

 

摘要
背景:
大量动物实验表明骨髓间充质干细胞移植能够促进皮肤损伤、肝损伤、肺损伤的修复;益母草具有活血祛瘀、调经的功效。
目的:验证骨髓间充质干细胞移植联合益母草碱治疗兔宫腔粘连的作用并探讨其机制。
方法:采用双重损伤法建立新西兰大白兔宫腔粘连模型,实验随机分为5组:假手术组、宫腔粘连组、骨髓间充质干细胞组、益母草碱组和骨髓间充质干细胞+益母草碱组(联合组)。假手术组切开子宫后不作任何处理,生理盐水冲洗后关腹;骨髓间充质干细胞组与联合组在子宫缝合前将骨髓间充质干细胞局部移植至子宫组织内;益母草碱组与联合组分别在造模后灌胃益母草碱4 mg/kg,共14 d。苏木精-伊红染色观察子宫内膜形态学变化,免疫组织化学染色法检测组织中转化生长因子β、Smad3的蛋白表达变化,实时荧光定量PCR(qPCR)检测IFN-γ的mRNA表达变化。
结果与结论:①与宫腔粘连组相比,骨髓间充质干细胞组、益母草碱组与联合组的宫腔粘连程度减轻,其中以联合组宫腔粘连程度最小;②与假手术组相比,宫腔粘连组的转化生长因子β、Smad3蛋白表达显著升高,干扰素γ的mRNA表达显著降低;与宫腔粘连组相比,骨髓间充质干细胞组、益母草碱组与联合组中转化生长因子β、Smad3蛋白表达显著降低,干扰素γ的mRNA表达显著升高,其中以联合组的变化程度最大。③结果证实骨髓间充质干细胞移植联合益母草碱能够显著改善宫腔粘连;其作用可能与转化生长因子β/Smad3通路有关。

Abstract:

BACKGROUND: Increasing evidence has demonstrated that bone marrow mesenchymal stem cell (BMSC) transplantation can promote skin, liver and lung repair in animal models; and Leonurus sibiricus L. has the ability of promoting blood circulation and regulating menstruation.
OBJECTIVE: To investigate the therapeutic effect of BMSC transplantation with leonurine on intrauterine adhesions (IUA) in rabbits and the relevant mechanism of action.
METHODS: After modeled using dual injury method, rabbit models of IUA were randomly divided into five groups: sham-operated group (sham), model group (IUA), BMSC transplantation group, leonurine treatment group and combined treatment group (BMSCs+leonurine). Rabbits in the sham group were only given normal saline rinsing after hysterotomy, while those in the latter three groups were correspondingly given intrauterine BMSC transplantation or/and intragastric administration of 4 mg/kg leonurine for 14 days. Morphological changes of the endometrium were observed using hematoxylin-eosin staining, and expression levels of transforming growth factor β protein, Smad3 protein and interferon-γ mRNA were detected using immunohistochemical staining and real-time fluorescence quantitative PCR, respectively.
RESULTS AND CONCLUSION: Compared with the model group, the degree of IUA was all significantly improved in the other groups, especially in the combined treatment group. Moreover, BMSC transplantation, leonurine treatment and their combined use all could inhibit IUA-induced increase of transforming growth factor β and Smad3 protein expression and IUA-induced decrease of interferon-γ mRNA level. Importantly, all these alternations were much more pronounced in the combined treatment group. Our results show that the combined use of BMSC transplantation and leonurine treatment can exert a synergistic effect in the improvement of IUA through the transforming growth factor β/Smad3 pathway.
