越来越多的证据表明,生长/分化因子,特别是GDF 5,6和7,可能在肌腱和韧带生物学中发挥作用。Gdf 5基因突变的小鼠具有改变的肌腱组成和机械行为,而Gdf 7功能无效突变的动物具有更微妙的肌腱表型。本研究首次证明,Gdf 6的无效突变与4周龄雄性小鼠尾腱胶原蛋白含量(-33%)显著降低相关,这对组织的机械完整性(材料性能降低45-50%)具有直接的功能后果。这些数据支持GDF 6在肌腱矩阵建模中的作用。
Increasing evidence suggests that the growth/differentiation factors, GDFs 5, 6, and 7 in particular, may play a role in tendon and ligament biology. Mice with genetic mutations in Gdf5 have altered tendon composition and mechanical behavior, while animals with functional null mutations in Gdf7 have a more subtle tendon phenotype. The present study demonstrates for the first time that a null mutation in Gdf6 is associated with substantially lower levels of tail tendon collagen content (−33%) in four-week-old male mice, which has direct functional consequences for the mechanical integrity of the tissue (45-50% reduction in material properties). These data support a role for GDF6 in tendon matrix modeling.
