中南大学湘雅医院袁灿、肖献忠等为深入研究心肌缺血预适应的分子机制 ,采用含 4 2 0 0个基因的ｃＤ ＮＡ芯片检测了大鼠心肌缺血预适应不同时间点的基因表达改变情况 ,并采用ＳＯＭ对具有相同表达模式的基因进行聚类分析 ,获得了多个新的与心肌缺血预适应相关的已知基因和可能 Yuan Can, Xiao Xianzhong, Xiangya Hospital of Central South University, etc. In order to further study the molecular mechanism of myocardial ischemic preconditioning, cD NA chips containing 4200 genes were used to detect the gene expression changes of myocardial ischemic preconditioning at different time points And using SOM clustering analysis of genes with the same expression pattern, obtained a number of new known genes related to myocardial ischemic preconditioning and possible
