目的探讨聚蛋白聚糖(aggrecan,ACAN)在泛癌中的表达,并聚焦乳腺癌分析其临床预后意义、免疫细胞浸润及功能富集分析。方法采用生物信息学分析ACAN在多种肿瘤组织及正常组织中的表达、临床预后;运用GEPIA 2、UALCAN、t.e Human Prot.in Alt.s多组学数据库分析ACAN在乳腺癌和正常乳腺组织中的表达;采用t.GA数据库分析ACAN在乳腺癌中的表达水平与临床病理参数及预后的关系;利用t.MER2.0数据库分析ACAN在乳腺癌中的表达水平与免疫细胞浸润的关系,并进一步了解ACAN与免疫检查点的关系;利用GeneMANIA和St.ING数据库构建ACAN基因与蛋白质互作网络;运用Met.scape数据库对ACAN相关基因进行功能富集分析。结果ACAN在多种肿瘤组织中差异表达,在乳腺癌组织中呈现高表达且为预后不良因素(Pt.B淋巴细胞低浸润、巨噬细胞和中性粒细胞高浸润相关(Pt.4、ADAMt.5、HAPLN1及COMP相互作用并参与人体多种生物学过程。结论ACAN在乳腺癌中表达水平增高,且ACAN高表达的乳腺癌患者预后较差,其机制可能与抑制t.B淋巴细胞浸润,促进巨噬细胞、中性粒细胞浸润有关。
