Proteome differences between hepatitis B virus genotype B and genotype C induced hepatocellular carcinoma revealed by iTRAQ based quantitative proteomics Journal of Proteome Research (PMID: ; IF= 4.173) 报告人：董浩 IMI CONFIDENTIAL

2 Background 分类：（基于LC-MS） 定性 定量 标记：SILAC、iTRAQ、 ICAT 非标记
bla 蛋白质组学（proteomics）是从整体角度分析细胞内蛋白质组成、表达变化、修饰状态，了解蛋白质之间的相互作用，从蛋白水平揭示蛋白质功能与细胞生命活动规律。 分类：（基于LC-MS） 定性 定量 标记：SILAC、iTRAQ、 ICAT 非标记 其研究内容主要包括：鉴定特定细胞、组织或器官的蛋白质种类（蛋白质组全谱鉴定）、特定条件下蛋白质的表达量变化研究（定量蛋白质组学）、明确蛋白质在生命活动中执行的功能（功能蛋白质组学）、揭示蛋白质之间的复杂相互作用机制（相互作用蛋白质组学）、描绘蛋白质的精确二维、三维以致四维结构（结构蛋白质组学）、以及蛋白质翻译后修饰研究（修饰蛋白质组学）。 IMI CONFIDENTIAL bla

3 Background 定量蛋白质组学 标记（label）定量：用不同的化学试剂或同位素作为标记物，对不同样品进行区别标记，然后混合、经过LC-MS/MS分析。 方法：SILAC：标记效率高，但只能针对细胞。 ICAT：兼容性广，但只能对含有半胱氨酸的肽段标记，且只能对两个样品标记。 iTRAQ：标记效率高、分离能力强、分析范围广、自动化程度高、定量结果准确。 IMI CONFIDENTIAL

KEGG分析：信号通路相关 聚类分析：展示作用 PPI分析：蛋白互作 IMI CONFIDENTIAL

5 Background 乙型肝炎病毒(HBV)是肝细胞癌的主要病因，HBV基因型B和C基因型是最普遍的。不同的病毒基因型对肝细胞癌的临床结果具有不同影响。然而,潜在的分子机制差异并不清楚。 目的：通过蛋白质组学方法分析 B、C基因型HBV引发的肝癌中蛋白质组差异，研究二者对肝癌发生的不同影响。 IMI CONFIDENTIAL
