摘要

摘要研究损伤后肌肉恢复过程中衰老对基底膜(BM)的影响。通过大鼠模型，我们发现衰老延迟了肌纤维和脑基恢复。此外，无论是年轻大鼠还是老年大鼠，在肌肉损伤后7天，脑损伤相关因子的表达均达到峰值。胶原合成因子的峰值表达随年龄的增长而降低，而降解因子的表达不受年龄的影响。这些结果表明，损伤后肌纤维和BM恢复的年龄相关延迟可能与胶原合成因子的抑制有关。

Effects of aging on basement membrane of tibialis anterior muscle during recovery following muscle injury in rats

Abstract We investigated the effect of aging on the basement membrane (BM) during postinjury muscle recovery. Using a rat model, we found that aging delayed muscle fiber and BM recovery. In addition, expression of BM-related factors peaked 7 days after muscle injury among both young and older rats. Peak expression of collagen IV synthetic factors decreased with age, whereas expression of the degradative factor was unaffected by age. These results suggest that age-related delays in postinjury muscle fiber and BM recovery may be related to the suppression of collagen IV synthetic factors.
