    摘要:

    目的 检测 Dlx 2 基因在小尾寒羊颅骨缺损模型颅骨组织中的表达,探讨其对颅骨缺损的意义?方法 选取10 只1 月龄小尾寒羊,建立颅骨缺损模型,对缺损部位的新生颅骨组织及邻近缺损部位的原生颅骨组织进行取材,应用Real?time PCR 和Western blot 技术检测 Dlx 2 的mRNA 和蛋白表达水平?结果 与邻近缺损部位的原生颅骨组织比较,缺损部位的新生颅骨组织 Dlx 2 mRNA 和蛋白表达水平显著升高( P < 0. 05)?结论 Dlx 2 基因表达增加可能对颅骨缺损修复有重要意义?

    Abstract:

    Objective To determine the expression of the Dlx 2 gene in skull tissue of the small?tailed Han sheep skull defect model, and to investigate its significance in this skull defect. Methods Ten small?tailed Han sheep aged one month old were selected to establish the skull defect model. Newborn skull tissue in the defect area and native skull tissue adjacent to the defect area were collected. Dlx 2 expression at the mRNA and protein levels was determined by real?time PCR and western blotting. Results Compared with the levels in native skull tissue adjacent to the defect area, the Dlx 2 mRNA and protein expression of newborn skull tissue in the defect area was significantly increased ( P < 0. 05). Conclusions Increased Dlx 2 gene expression may play an important role in the repair of skull defects.
