CDKN2A is a tumor suppressor located in chromosome 9p21 and frequently lost in Barrett’s esophagus (BE) and esophageal adenocarcinoma (EAC). How CDKN2A and other 9p21 gene co-deletions affect EAC evolution remains understudied. We explored the effects of 9p21 loss in EACs and cancer progressor and non-progressor BEs with matched genomic, transcriptomic and clinical data. Despite its cancer driver role, CDKN2A loss in BE prevents EAC initiation by counterselecting subsequent TP53 alterations. 9p21 gene co-deletions predict poor patient survival in EAC but not BE through context-dependent effects on cell cycle, oxidative phosphorylation and interferon response. Immune quantifications using bulk transcriptome, RNAscope and high-dimensional tissue imaging showed that IFNE loss reduces immune infiltration in BE, but not EAC. Mechanistically, CDKN2A loss suppresses the maintenance of squamous epithelium, contributing to a more aggressive phenotype. Our study demonstrates context-dependent roles of cancer genes during disease evolution, with consequences for cancer detection and patient management. Ganguli et al. show that CDKN2A loss in Barrett’s esophagus prevents esophageal adenocarcinoma initiation by counterselecting subsequent TP53 loss and report context-dependent effects of 9p21 gene co-deletions on disease progression.
CDKN2A是一种位于染色体9p21上的肿瘤抑制因子,在巴雷特食管(BE)和食管腺癌(EAC)中经常丢失。CDKN2A和其他9p21基因共缺失如何影响EAC进化仍有待研究。我们利用匹配的基因组、转录组学和临床数据,探讨了9p21缺失对EACs、癌症进展者和非进展者的影响。尽管它具有癌症驱动作用,但BE中CDKN2A的缺失通过反选择随后的TP53改变来阻止EAC的启动。通过对细胞周期、氧化磷酸化和干扰素反应的环境依赖性影响,9p21基因共缺失预测EAC患者的生存期较差,但不预测BE。使用大量转录组、RNAscope和高维组织成像的免疫定量分析显示,IFNE丢失会减少BE的免疫浸润,但不会减少EAC。从机制上讲,CDKN2A的缺失抑制了鳞状上皮的维持,导致更具侵袭性的表型。我们的研究证明了癌症基因在疾病进化过程中的环境依赖作用,以及癌症检测和患者管理的后果。

Circulating tumor cells (CTCs) drive metastasis, the leading cause of death in individuals with breast cancer. Due to their low abundance in the circulation, robust CTC expansion protocols are urgently needed to effectively study disease progression and therapy responses. Here we present the establishment of long-term CTC-derived organoids from female individuals with metastatic breast cancer. Multiomics analysis of CTC-derived organoids along with preclinical modeling with xenografts identified neuregulin 1 (NRG1)–ERBB2 receptor tyrosine kinase 3 (ERBB3/HER3) signaling as a key pathway required for CTC survival, growth and dissemination. Genome-wide CRISPR activation screens revealed that fibroblast growth factor receptor 1 (FGFR1) signaling serves a compensatory function to the NRG1–HER3 axis and rescues NRG1 deficiency in CTCs. Conversely, NRG1–HER3 activation induced resistance to FGFR1 inhibition, whereas combinatorial blockade impaired CTC growth. The dynamic interplay between NRG1–HER3 and FGFR1 signaling reveals the molecular basis of cancer cell plasticity and clinically relevant strategies to target it. Our CTC organoid platform enables the identification and validation of patient-specific vulnerabilities and represents an innovative tool for precision medicine. Trumpp and colleagues develop a method to obtain long-term circulating tumor cell-derived organoids from individuals with metastatic breast cancer and identify the neuregulin 1–HER3 axis as important for organoid growth and a promising therapeutic target.
循环肿瘤细胞(ctc)驱动转移,是乳腺癌患者死亡的主要原因。由于它们在循环中的丰度较低,迫切需要强有力的CTC扩增方案来有效研究疾病进展和治疗反应。在这里,我们提出建立长期ctc来源的类器官从女性个体转移性乳腺癌。对CTC衍生类器官的多组学分析以及异种移植物临床前建模发现,神经调节蛋白1 (NRG1)-ERBB2受体酪氨酸激酶3 (ERBB3/HER3)信号通路是CTC存活、生长和传播所需的关键途径。全基因组CRISPR激活筛选显示,成纤维细胞生长因子受体1 (FGFR1)信号通路对NRG1- her3轴具有代偿功能,并可挽救CTCs中的NRG1缺陷。相反,NRG1-HER3激活诱导对FGFR1抑制的抗性,而联合阻断则会损害CTC的生长。NRG1-HER3和FGFR1信号传导之间的动态相互作用揭示了癌细胞可塑性的分子基础和临床相关的靶向策略。我们的CTC类器官平台能够识别和验证患者特定的脆弱性,代表了精准医疗的创新工具。

The coronavirus disease 2019 pandemic substantially impacted the delivery of cancer services and programs. Here we reviewed and synthesized the global scale and impact of pandemic-related delays and disruptions on cancer services, including diagnosis, diagnostic procedures, screening, treatment and supportive and palliative care. Based on data from 245 articles in 46 countries, we observed declines in the number of cancer screening participation (39.0%), diagnoses (23.0%), diagnostic procedures (24.0%) and treatment (28.0%), ranging from a 15.0% decline for radiotherapy to a 35.0% decline for systemic treatment during the pandemic compared to during the prepandemic period. Medium-human development index (HDI) category countries experienced greater reductions than high- and very-high-HDI countries. Missing data from low-HDI countries emphasize the need for increased investments in cancer surveillance and research in these settings. PROSPERO registration: CRD42022301816 Shah et al. conducted a systematic review and meta-analysis of the impact of COVID-19 pandemic-related disruptions to cancer healthcare services and reported reduced cancer screening, diagnosis and treatment of patients.
2019年冠状病毒病大流行严重影响了癌症服务和项目的提供。在这里,我们回顾并综合了与大流行相关的延迟和中断对癌症服务的全球规模和影响,包括诊断、诊断程序、筛查、治疗以及支持和姑息治疗。根据46个国家245篇文章的数据,我们观察到,与大流行前相比,大流行期间,癌症筛查参与(39.0%)、诊断(23.0%)、诊断程序(24.0%)和治疗(28.0%)的数量下降,从放射治疗下降15.0%到全身治疗下降35.0%不等。中等人类发展指数(HDI)类别国家比高和非常高人类发展指数国家减少得更多。低人类发展指数国家缺少的数据强调了在这些环境中需要增加对癌症监测和研究的投资。普洛斯彼罗注册号:CRD42022301816。

The cerebrospinal fluid (CSF) border accommodates diverse immune cells that permit peripheral cell immunosurveillance. However, the intricate interactions between CSF immune cells and infiltrating cancer cells remain poorly understood. Here we use fate mapping, longitudinal time-lapse imaging and multiomics technologies to investigate the precise origin, cellular crosstalk and molecular landscape of macrophages that contribute to leptomeningeal metastasis (LM) progression. Mechanically, we find that dura-derived LM-associated macrophages (dLAMs) migrate into the CSF in a matrix metalloproteinase 14 (MMP14)-dependent manner. Furthermore, we identify that dLAMs critically require the presence of secreted phosphoprotein 1 (SPP1) in cancer cells for their recruitment, fostering an immunosuppressed microenvironment characterized by T cell exhaustion and inactivation. Conversely, inhibition of the SPP1–MMP14 axis can impede macrophages from bypassing the border barrier, prevent cancer cell growth and improve survival in LM mouse models. Our findings reveal an unexpectedly private source of innate immunity within the meningeal space, shed light on CSF barrier dysfunction dynamics and supply potential targets of clinical immunotherapy. Zhao et al. find that a macrophage subset migrates from the dura matter to reshape the cerebrospinal fluid microenvironment and promote metastasis and show that the secreted phosphoprotein 1–matrix metallopeptidase 14 axis can be targeted to inhibit this.
脑脊液(CSF)边界容纳多种免疫细胞,允许外周细胞免疫监视。然而,脑脊液免疫细胞与浸润性癌细胞之间复杂的相互作用仍然知之甚少。在这里,我们使用命运图谱、纵向延时成像和多组学技术来研究巨噬细胞的精确起源、细胞串扰和分子景观,这些巨噬细胞有助于瘦脑膜转移(LM)的进展。机械上,我们发现硬脑膜衍生的lm相关巨噬细胞(dram)以基质金属蛋白酶14 (MMP14)依赖的方式迁移到CSF中。此外,我们发现dram需要癌细胞中分泌磷酸化蛋白1 (SPP1)的存在才能募集,从而形成以T细胞衰竭和失活为特征的免疫抑制微环境。相反,抑制SPP1-MMP14轴可以阻止巨噬细胞绕过边界屏障,阻止癌细胞生长,提高LM小鼠模型的存活率。我们的发现揭示了脑膜空间内先天免疫的一个意想不到的私人来源,揭示了脑脊液屏障功能障碍动力学,并提供了临床免疫治疗的潜在靶点。Zhao等人发现巨噬细胞亚群从硬脑膜迁移,重塑脑脊液微环境,促进转移,并表明分泌的磷酸化蛋白1 -基质金属肽酶14轴可被靶向抑制。
