Adenomyosis is one of the most common gynecological disorders that the molecular events underlying its pathogenesis remain not fully understood. Prior studies have shown that endometrial stromal cells (ESCs) played crucial roles in the pathogenesis of adenomyosis. In this study, we utilized two-dimensional gel electrophoresis combined with protein identification by mass spectrometry (2D/MS) proteomics analysis to compare the differential protein expression profile between the paired eutopic and ectopic ESCs (EuESCs and EcESCs) in adenomyosis, and a total of 32 significantly altered protein spots were identified. Among which, the expression of LIM and SH3 protein 1 (LASP1) was increased significantly in EcESCs compared to EuESCs. Immunohistochemical assay showed that LASP1 was overexpressed in the stromal cells of ectopic endometriums compared to eutopic endometriums; further functional analyses revealed that LASP1 overexpression could enhance cell proliferation, migration and invasion of EcESCs. Furthermore, we also showed that the dysregulated expression of LASP1 in EcESCs was associated with DNA hypermethylation in the promoter region of the LASP1 gene. However, the detailed molecular mechanisms of enhancing cell proliferation, invasion and migration caused by upregulated LASP1 in adenomyosis needs further study. For the first time, our data suggested that LASP1 plays important roles in the pathogenesis of adenomyosis, and could serve as a prognostic biomarker of adenomyosis.

子宫内膜基质细胞蛋白质组学分析揭示 LIM 和 SH3 蛋白 1 (LASP1) 在子宫腺肌症的进展中起重要作用

子宫腺肌病是最常见的妇科疾病之一,其发病机制的分子事件仍未完全了解。先前的研究表明,子宫内膜基质细胞(ESCs)在子宫腺肌病的发病机制中起着至关重要的作用。在这项研究中,我们利用二维凝胶电泳结合质谱(2D/MS)蛋白质组学分析来比较子宫腺肌病中配对的在位和异位胚胎干细胞(EuESCs和EcESCs)之间的差异蛋白表达谱,以及总确定了 32 个显着改变的蛋白质点。其中,与EuESCs相比,EcESCs中LIM和SH3蛋白1(LASP1)的表达显着增加。免疫组织化学分析显示,与在位子宫内膜相比,LASP1 在异位子宫内膜的基质细胞中过表达;进一步的功能分析表明,LASP1 过表达可以增强 EcESCs 的细胞增殖、迁移和侵袭。此外,我们还发现 EcESCs 中 LASP1 的失调表达与 LASP1 基因启动子区域的 DNA 高甲基化有关。然而,上调LASP1在子宫腺肌病中增强细胞增殖、侵袭和迁移的详细分子机制需要进一步研究。我们的数据首次表明 LASP1 在子宫腺肌病的发病机制中起重要作用,并可作为子宫腺肌病的预后生物标志物。进一步的功能分析表明,LASP1 过表达可以增强 EcESCs 的细胞增殖、迁移和侵袭。此外,我们还发现 EcESCs 中 LASP1 的失调表达与 LASP1 基因启动子区域的 DNA 高甲基化有关。然而,上调LASP1在子宫腺肌病中增强细胞增殖、侵袭和迁移的详细分子机制需要进一步研究。我们的数据首次表明 LASP1 在子宫腺肌病的发病机制中起重要作用,并可作为子宫腺肌病的预后生物标志物。进一步的功能分析表明,LASP1 过表达可以增强 EcESCs 的细胞增殖、迁移和侵袭。此外,我们还发现 EcESCs 中 LASP1 的失调表达与 LASP1 基因启动子区域的 DNA 高甲基化有关。然而,上调LASP1在子宫腺肌病中增强细胞增殖、侵袭和迁移的详细分子机制需要进一步研究。我们的数据首次表明 LASP1 在子宫腺肌病的发病机制中起重要作用,并可作为子宫腺肌病的预后生物标志物。上调LASP1在子宫腺肌病中增强细胞增殖、侵袭和迁移的详细分子机制有待进一步研究。我们的数据首次表明 LASP1 在子宫腺肌病的发病机制中起重要作用,并可作为子宫腺肌病的预后生物标志物。上调LASP1在子宫腺肌病中增强细胞增殖、侵袭和迁移的详细分子机制有待进一步研究。我们的数据首次表明 LASP1 在子宫腺肌病的发病机制中起重要作用,并可作为子宫腺肌病的预后生物标志物。
