  • 📝 描述:Contributors : Yang Liu ; Dejiang Wang ; Xiangjun Di ; Shenjie WangSeries Type : OtherOrganism : Homo sapiens ; Mus musculusTumor heterogeneity arises from the sequential acquisition of somatic mutations and the selection of fitter clones, leading to distinct genotypes and phenotypes. Joint mapping of genome and transcriptome in the same tumor tissue can directly link clonoal relation to transcriptional state enabling a more in-depth understanding of intrinsic and extrinct tumor heterogeneity in the tissue context. Here, we introduce Spatial-GT-seq, a spatial multi-omic technology capable of genome-wide co-profiling of the genome and transcriptome at near single-cell resolution. We demonstrated in situ identification of tumor subclones in a mouse model of lung metastasis, with parallel transcriptomic profiles indicating that the gene expression profile of the same tumor clone is altered by the tumor microenvironment. Furthermore, analysis of primary and recurrent human pancreatic neuroendocrine tumors reveals both persistent and newly emerging tumor subclones, exhibiting transcriptional changes in both the original and recurrence sites. These findings highlight Spatial-GT-seq as a valuable platform for studying genotype-phenotype-microenvironment associations, providing new insights into cancer evolution and heterogeneity.

Treatment is guided by its proximal counterpart, colorectal cancer (CRC), despite recent studies demonstrating AA’s unique mutational landscape and poor response to CRC chemotherapy. As the first application of single-cell technology to AA these data provide insight into the intratumor heterogeneity of AA and highlight the important contribution of the tumor microenvironment in this orphan disease. These results also reinforce multiple observations that AA is a unique disease entity from CRC and targeting the tumor microenvironment should be considered as a therapeutic strategy.

  • 📝 描述:Contributors : Mengwei Li ; Congyi Zhang ; Wenqiu Cai ; Feng Ren ; Xintong ChenSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensRenal cell carcinoma (RCC) is among the most common urological malignancies, yet the transcriptomic landscape underlying its pathogenesis remains incompletely characterized, particularly for non-coding regions that may harbor functional non-canonical open reading frames (ncORFs). Here we performed whole-transcriptome RNA-seq on 5 clear cell RCC tumor tissues and 5 adjacent normal kidney tissues to systematically profile mRNA, lncRNA, and circRNA expression. This dataset serves as the transcriptomic layer of an integrative multi-omics study aimed at identifying dysregulated ncORF-encoded micropeptides in RCC, with lncRNAs representing a predominant source of tumor-associated cryptic peptides. The data provide a reference for translational activity assessment when combined with matchedribosome profiling and immunopeptidomics datasets.

6. ⭐ GSE345263 成人骨髓中的 CD4 谱系红系髓系祖细胞定义了巨噬细胞生成的替代途径 [RNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:macrophage、RNA-seq、pathway
  • 📝 描述:Contributors : Tikoo Shweta ; Jain Rohit ; Weninger Wolfgang ; Wielscher Matthias ; Farlik MatthiasSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusTissue-resident macrophages originate from distinct developmental sources, but in adulthood, their replenishment is thought to depend exclusively on circulating monocytes. Here, we identify a previously unrecognized CD4-lineage erythro-myeloid progenitor, termed EMPROR (Erythro-Myeloid Progenitor), that resides in the adult bone marrow and defines an alternative pathway for generating macrophages. EMPROR cells are phenotypically and transcriptionally distinct from hematopoietic stem cells, common myeloid progenitors, and monocyte precursors. They lack expression of Csf1r and Ccr2 while expressing Cd4 and c-Kit. Single-cell RNA sequencing, RNA velocity analysis, and in vitro and in vivo lineage assays demonstrate a multilineage potential encompassing macrophage, neutrophil, megakaryocytic, and erythroid fates. In vivo, EMPROR cells efficiently generate perivascular and tumor-associated macrophages independently of CCR2-mediated monocyte recruitment, and also contribute to erythroid and granulocytic lineages under inflammatory and neoplastic conditions. Transcriptomic comparisons position EMPROR cells closest to embryonic erythro-myeloid progenitors, indicating that an embryonic-like erythro-myeloid program persists within the adult bone marrow. These findings expand current models of adult myelopoiesis and highlight a previously unappreciated developmental pathway that sustains macrophage diversity beyond the classical monocyte lineage.

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、immunity、antigen
  • 📝 描述:Contributors : Masateru Yamamoto ; Kyoko Fukuda ; Yasushi UemuraSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiens ; Mus musculusActivation of cancer-reactive T cells by dendritic cells (DCs) is important for cancer elimination by host immunity. One type of cancer immunotherapy in which DCs loaded with “cancer antigens” are administered has not been able to achieve stable efficacy due to heterogeneity in cell quality dependent on patient DC status. We constructed IL12-producing antigen-presenting cells from mouse induced pluripotent stem cells (iPSC). These cells can be controlled to proliferate using cytokines, allowing for the mass production of cells with stable performance. When these cells were loaded with a model cancer antigen and administered to cancer-bearing mice, cancer-reactive T cells rapidly acquired effector functions and propagated an interferon (IFN)-stimulated gene signature to cancer tissue distant from the site of administration. This was accompanied by infiltration of effector cells into the cancer tissue, while associated with a decrease in myeloid-derived suppressor cells. These were extremely more potent than immune checkpoint inhibitors (ICIs) and were further amplified in combination with ICIs and correlated with antitumor effects. Based on these observations, we constructed IL12-producing antigen-presenting cells from human iPSCs that express only HLA molecules involved in cancer antigen presentation and exclude other HLA molecules for improved versatility. These human cells, like their mouse counterparts, were capable of cytokine-regulated proliferation and induced antigen-specific activation and IFN-γ production of cancer antigen-specific T cells. Thus, these cells may become an alternative antigen-presenting cell platform for patient DCs to overcome HLA polymorphisms and ensure stable supply and quality.

9. ⭐ GSE301083 HOXA9 重编程 3D 基因组结构以调节急性髓系白血病中的致癌转录 [CUT&RUN]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:leukemia、regex:onco(logy|logist|gene|genic)、genome
  • 📝 描述:Contributors : Xueqing Wang ; Wentao Yang ; Fan Fang ; Yali DouSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensThe hierarchical three-dimensional (3D) organization of chromatin underpins the spatial and temporal control of gene expression during development. This principle is exemplified by the Hox gene clusters, where dynamic topological architecture governs precise transcriptional activation. While disruption of chromatin organization at Hox genes is increasingly recognized in various human malignancies, the extent to which Hox genes themselves contribute to shaping 3D genome architecture remains poorly understood. In particular, it is unknown whether oncogenic overexpression of HOXA9—a highly conserved transcription factor and common downstream effector of diverse genetic alterations in acute myeloid leukemia (AML)—can actively reprogram chromatin topology. Here, we uncover a pivotal role for HOXA9 as a master regulator of 3D chromatin architecture in human AML. We demonstrate that HOXA9 orchestrates a leukemia-specific reconfiguration of chromatin topology. HOXA9 promotes the formation of leukemia specific topologically associating domains (TADs) and establishes long-range enhancer–promoter interactions essential for maintaining the leukemic transcriptional program. Perturbation of HOXA9 leads to widespread architectural collapse, marked by the dissolution of chromatin loops, disrupted enhancer communication, and silencing of critical leukemogenic genes. Furthermore, HOXA9-mediated chromatin looping occurs independently of CTCF. Instead, HOXA9 functions through the cohesin complex to facilitate higher-order genome organization, thereby functioning as a non-canonical architectural factor. Among its targets, we identify NHLRC2 as a HOXA9-associated loop gene essential for leukemic cell survival and proliferation. Collectively, these findings uncover a previously unappreciated architectural function of HOXA9 in modulating 3D genome organization and sustaining oncogenic gene expression in AML. More broadly, they suggest a mechanistic paradigm in which HOX transcription factors actively reprogram nuclear architecture to enforce lineage-specific or malignant gene expression programs.
