Hum Mol Genet:肌营养不良发育过程中肌营养不良蛋白/肌营养不良蛋白双敲除小鼠骨骼和肌肉异常的系统研究及其机制

2019-02-01 MedSci MedSci原创

肌营养不良蛋白- /- / utrophin - /- 双敲除(dKO-Hom)小鼠是人Duchenne肌营养不良症(DMD)的鼠模型。该研究调查了dKO-Hom小鼠的骨骼和肌肉异常及其机制。我们收集了来自对照小鼠和不同年龄的三种肌营养不良小鼠模型的骨骼和骨骼肌样品,并对骨骼和骨骼肌组织进行了MicroCT和组织学分析。还分析了血清RANKL和SOST水平,破骨细胞生成和血清蛋白质组学。结果表明,

肌营养不良蛋白- /- / utrophin - /- 双敲除(dKO-Hom)小鼠是人Duchenne肌营养不良症(DMD)的鼠模型。该研究调查了dKO-Hom小鼠的骨骼和肌肉异常及其机制。

我们收集了来自对照小鼠和不同年龄的三种肌营养不良小鼠模型的骨骼和骨骼肌样品,并对骨骼和骨骼肌组织进行了MicroCT和组织学分析。还分析了血清RANKL和SOST水平,破骨细胞生成和血清蛋白质组学。

结果表明,dKO-Hom小鼠在5日龄时出现骨骼肌组织病理学,而4周龄时出现骨骼异常。此外,我们的结果表明,与WT小鼠相比,dKO-Hom小鼠的胫骨近端和脊柱骨小梁中成骨细胞和破骨细胞的数量减少,这与血清RANKL水平的显着降低相关。胫骨皮质骨细胞的数量也减少,而dKO-Hom小鼠的血清SOST水平显着高于WT小鼠。在6周龄时,dKO-Hom小鼠的脊柱L6中的成骨细胞数显著降低,但破骨细胞数量增加,导致骨形成减少和骨吸收增加。血清蛋白质组学结果显示,与对照小鼠相比,dKO-Hom小鼠的蛋白质组特征异常。

总之,该研究阐明了骨骼和肌肉异常的发展时间。dKO-Hom小鼠的骨异常与较低的血清RANK L和较高的Sost水平相关,这导致骨生成和破骨细胞生成和骨丢失的失调。
