摘要
目的:研究太极拳运动对骨骼肌全基因组表达的影响及太极拳促进健康的分子机制。方法:6名健康的老年人(65.5±8.9岁)参加了为期12周的太极拳训练。在训练前后分别对实验对象进行肌活验,提取总RNA,经处理后与Affymetrix U133A基因芯片进行杂交,分析数据。结果:太极拳运动使老年人骨骼肌全基因组表达发生明显改变,筛选出725条表达有差异的基因。本文对表达差异最显著的20条差异表达基因进行研究(3条基因表达上调,17条基因表达下调)。根据基因功能分类对比,差异表达基因分别归属8种细胞组分和生物过程,经KEGG搜索找到4条基因的代谢途径。结论:太极拳运动有助保持神经系统的灵敏性,提高反应能力,有助于抗衰老和减肥等,而不利于骨骼肌蛋白质的合成。
