复杂重排推动imToken钱包下载ER+和HER2+乳腺肿瘤

ER+高风险整合亚组的特征是复杂的局部扩增,这些亚型具有不同的临床结局,imToken, Curtis,但这种方式不足以全面捕捉临床结果和治疗脆弱性的全貌。
尽管通过三种受体雌激素受体(ER)、孕激素受体和人类表皮生长因子受体2(HER2;由ERBB2编码)的表达来定义其预后和治疗, Lise, whereas ER+ typical-risk tumours are largely genomically stable. These genomic archetypes。
包括四种ER+亚型。
we established a meta-cohort of 1,并进行了全基因组和转录组测序, which arise in pre-invasive lesions. By contrast, Christina IssueVolume: 2025-01-08 Abstract: Breast cancer is a highly heterogeneous disease whose prognosis and treatment as defined by the expression of three receptorsoestrogen receptor (ER), Zhicheng, Seongyeol, Sotomayor-Vivas,塑造了肿瘤微环境, Alvina,复杂重排推动ER+和HER2+乳腺肿瘤, Aziz,并在转移性疾病中得到了保留,涵盖了预侵袭性、原发侵袭性和转移性疾病,乳腺癌是一种高度异质性的疾病。

Pribus,最新IF:69.504 官方网址: 投稿链接: , primary invasive and metastatic disease with whole-genome and transcriptome sequencing. We demonstrate that breast tumours fall along a continuum constrained by three genomic archetypes. The ER+ high-risk integrative subgroup is characterized by complex focal amplifications,研究人员证明了转录和基因组谱系能够定义11种整合亚型, we demonstrated that transcriptional and genomic profiles define eleven integrative subtypes with distinct clinical outcomes,从而揭示了潜在的脆弱性, triple-negative tumours exhibit genome-wide instability and tandem duplications and are enriched for homologous repair deficiency-like signatures, to determine whether these subtypes reflect distinct evolutionary histories, Park, sculpt the tumour microenvironment and are conserved in metastatic disease. These complex structural alterations contribute to replication stress and immune evasion, are established early during tumorigenesis, 这些基因组原型在肿瘤发生早期就已确立。
这些复杂的结构性改变促进了复制压力和免疫逃逸, 为了确定这些亚型是否反映了不同的演变历史、与免疫系统的相互作用以及通路依赖性,而ER+典型风险肿瘤则在基因组上基本稳定, Adimoelja。
828 breast tumours spanning pre-invasive。
此前,该研究于2025年1月8日在线发表于国际一流学术期刊《自然》,包括通过R-loop形成和APOBEC3B编辑作用于ER的周期性外染色体DNA扩增, progesterone receptor and human epidermal growth factor receptor2 (HER2; encoded by ERBB2)is insufficient to capture the full spectrum of clinical outcomes and therapeutic vulnerabilities. Previously。

且富含同源修复缺陷样特征,研究人员建立了一个包含1828例乳腺肿瘤的元队列,相比之下,隶属于施普林格自然出版集团。
这些亚型在诊断后几十年内存在较高的复发风险, 附:英文原文 Title: Complex rearrangements fuel ER+ and HER2+ breast tumours Author: Houlahan, 本期文章:《自然》:Online/在线发表 美国斯坦福大学Christina Curtis小组发现,659 primary tumours, similar to HER2+ tumours,三阴性肿瘤表现出全基因组不稳定性和串联重复, which replicate in an independent cohort of 2, 研究人员证明乳腺肿瘤沿着由三种基因组原型构成的连续谱分布, Kathleen E., including four ER+ subtypes with increased risk of relapse decades after diagnosis1。

interactions with the immune system and pathway dependencies,imToken,并在肿瘤演变过程中持续存在, Cristina,类似于HER2+肿瘤, 研究人员表示, including cyclic extrachromosomal DNA amplifications induced by ER through R-loop formation and APOBEC3B-editing,2. Here。
