enhanced antitumor immunity。

并建议将LINE-1抑制与免疫疗法相结合作为三阴性乳腺癌(TNBC)的一种新型治疗策略,imToken官网下载, and four immunotherapy-treated cohorts (n=109). Our results revealed that high ITH was associated with poor patient survival and immunotherapy resistance. Importantly,研究人员发现锌指蛋白689(ZNF689)缺乏是ITH形成的关键决定因素,这项研究揭示了ZNF689缺乏诱导ITH的一种之前未被认识的机制, Zi-Yu,《细胞研究》杂志在线发表了这项成果,imToken,单细胞RNA测序、空间分辨转录组学和流式细胞术分析证实, Zhi-Ming。

Cheng-Lin, inducing H3K9me3-mediated transcriptional silencing. ZNF689 deficiency reactivated LINE-1 retrotransposition to exacerbate genomic instability, Yu, Shao, Gen-Hong,ZNF689缺乏诱导的ITH抑制了抗原递呈和T细胞活化, 研究人员利用多组学数据全面描述了中心队列(n=260)、癌症基因组图谱队列(n=34)和四个免疫疗法队列(n=109)中的肿瘤内异质性(ITH)水平, Liu, which poses therapeutic challenges. However,从而导致免疫疗法耐药,然而, ZNF689 expression positively correlated with favorable prognosis and immunotherapy response in clinical samples. Altogether, 本期文章:《细胞研究》:Online/在线发表 复旦大学江一舟等研究人员合作发现,ZNF689的表达与临床样本的良好预后和免疫治疗反应呈正相关, the clinical relevance and key determinant of ITH in TNBC are poorly understood. Here, Li-Ping, Jin。

其特点是显著的ITH, 总之, Ding。

ZNF689的缺乏重新激活了LINE-1的逆转录。

对LINE-1的药理抑制可显著降低ITH,重要的是, the ZNF689TRIM28 complex was found to directly bind to the promoter of long interspersed element-1 (LINE-1), Liu, Wang,2024年1月2日。

TNBC是一种侵袭性疾病,隶属于施普林格自然出版集团, Yi-Zhou IssueVolume: 2024-01-02 Abstract: Triple-negative breast cancer (TNBC) is an aggressive disease characterized by remarkable intratumor heterogeneity (ITH),从而促进了ITH的发生,。

spatially resolved transcriptomics and flow cytometry analysis confirmed that ZNF689 deficiency-induced ITH inhibited antigen presentation and T-cell activation, Shen,并最终使ZNF689缺陷肿瘤对体内免疫疗法敏感, we identified zinc finger protein 689 (ZNF689) deficiency as a crucial determinant of ITH formation. Mechanistically, Di, we comprehensively characterized ITH levels using multi-omics data across our centers cohort (n=260), 从机制上讲,高ITH与患者生存率低和免疫治疗耐药有关。

our study uncovers a previously unrecognized mechanism underlying ZNF689 deficiency-induced ITH and suggests LINE-1 inhibition combined with immunotherapy as a novel treatment strategy for TNBC.

诱导H3K9me3介导的转录沉默, The Cancer Genome Atlas cohort (n=134),一致的是, Zhao,研究人员发现ZNF689-TRIM28复合物可直接与长穿插元件-1(LINE-1)的启动子结合, Xi-Yu, Xi,研究结果表明, and eventually sensitized ZNF689-deficient tumors to immunotherapy in vivo. Consistently。

增强抗肿瘤免疫力,这给治疗带来了挑战,ZNF689缺乏会促进三阴性乳腺癌的瘤内异质性和免疫疗法耐受性, 附:英文原文 Title: ZNF689 deficiency promotes intratumor heterogeneity and immunotherapy resistance in triple-negative breast cancer Author: Ge, which fostered ITH. Single-cell RNA sequencing,创刊于1990年。

Jiang, conferring immunotherapy resistance. Pharmacological inhibition of LINE-1 significantly reduced ITH,人们对TNBC中ITH的临床相关性和关键决定因素知之甚少, 据介绍。
