摘　　要：缺血性心肌损伤的分子病理机制一直备受国际关注。该文应用C57BL/6品系的野生型(WT)小鼠、极低密度脂蛋白(Very Low Density Lipoprotein,VLDL)受体基因敲除(VLDLR-KO)小鼠、心脏特异性转基因(VLDLR-TG)小鼠,通过在体及离体实验研究VLDL受体对小鼠缺血性心肌损伤的影响,构建生物分子网络研究VLDL受体发挥生物学功能的关键分子及其关键信号通路。通过生物网络的功能模块计算,发现了VLDL受体→MAPKs、AKT、NF-κB信号通路→心肌损伤病理表型的因果关联性,阐明了VLDL受体影响缺血性心肌损伤的分子机制。The molecular mechanism of ischemic myocardial injury is still a hot topic in the international academic circles.In this paper,C57 BL/6 wild type（WT） mouse strains,very low density lipoprotein（VLDL） receptor knockout（VLDLR-KO） mice and VLDL receptor transgenic（VLDLR-TG） mice,were selected to investigate on the effect of VLDL receptor on myocardial ischemic injury in vivo and in vitro.Key molecular signaling pathways were found based on the biomolecular network analyses.A causal relationship between VLDL receptor→MAPKs,AKT,NF-κB signaling pathway and the pathological phenotype of myocardial infarction,was identified by computational analysis of functional modules across biological networks,to illustrate the effect of VLDL receptor molecular mechanism in myocardial ischemic injury.
