摘要

摘要

En 中文
皮肤是人体最大的器官,也是多种疾病的发生部位。然而,由于皮肤组织的复杂性,文献中关于皮肤蛋白质组学的数据有限。在此,我们提出了一种改良且优化的蛋白质提取方案,结合化学和机械裂解方法从人体皮肤中提取蛋白质。为此,我们使用了含2% SDS、50 mM TEAB以及1%蛋白酶和磷酸酶抑制剂混合物的裂解缓冲液,并辅以Matrix A珠和FastPrep-24 5G匀质仪。为表征样品,所获得的蛋白质经纯化并用SP3方法(单锅固相样品制备)进行酶解,随后通过纳升液相色谱-串联质谱进行分析。通过这种方法,我们在健康个体及孢子丝菌病真菌感染患者的皮肤样本中鉴定出约6000种蛋白质。我们的改进方法有望显著加深对皮肤生物学的理解,并为皮肤疾病的生物标志物和 therapeutic targets 的发现提供新视角。
