  • 📝 描述:Contributor : Dongyang ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensGiant cell tumor of bone (GCTB) is intermediate, locally aggressive primary bone tumor that are usually occur in long bones and typically present as lytic lesions, leading to cortical expansion or destruction with a soft-tissue component. At present, the main treatment of GCTB is surgical curettage and bone cement filling, but the recurrence rate is more than 20%. It is known that tumor recurrence and immune escape are closely related to the microenvironment. We need a deeper understanding of the complex tumor microenvironment, as well as the role of various immune cells in the development of GCTB, in order to achieve a comprehensive treatment of GCTB.

However, the histone modification landscape inprofile of ESCC remains poorly characterized, especially from human clinical samplesunderstood. Here, we performed comprehensive histone modification profiling of paired samples from 122 ESCC patients, identifying numerous aberrantly expressed histone modification sitesand identified a number of modification sites that are aberrantly expressed in ESCC. Most of these alterations correlate with patient survivalMost of these differentially expressed histone modification sites are associated with survival in ESCC patients. In particular, H3K27ac is aberrantly expressed in tumor tissue and stroma and its high expression is significantly correlated with poor prognosis of ESCC patients. We analyzed the H3K27ac ChIP-seq data for primary ESCC tumor tissues and ESCC cell lines and identified hundreds of altered putative super-enhancers (SEs) in ESCC tissues respectively relative to ESCC cell lines. Moreover, these differential SEs contribute to the transcriptomic aberrations in ESCC tissues. Genes regulated by ESCC tissue- gained SEs are highly expressed in ESCC tissues compared to ESCCthan in cell lines and are mostly enriched in microenvironment-related pathways. We definerefer to these SEs as tumor microenvironment-acquired super-enhancers (TMEA-SEs). Through integrative analysis of ChIP-seq, RNA-seq, scRNA-seq and ATAC-seq data, we identified a TMEA-SE activated in cancer-associated fibroblasts (CAFs) and found that IL1R1 is directly regulated by this TMEA-SE. We demonstrated that IL1R1 activation can affect CAFs to promotes ESCC cells migration and invasion via CAFs. Collectively, our findings these observations reveal that a critical oncogenic mechanism in ESCC whereby TMEA-SE drive malignancy by activating IL1R1 in CAFs.

  • 🏷️ 关键词:immune、spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Yucheng Tang ; Chunhua Zhu ; Aihua Zhang ; Enrico PetrettoSeries Type : OtherOrganism : Homo sapiensImmune dysregulation is a hallmark of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), particularly in the kidney; however, the spatial organization of renal microenvironments remains poorly understood. Here, we applied spatial transcriptomics to renal biopsies from pediatric patients with AAV representing distinct histological classes defined by the Berden classification (4 control, 2 focal, and 3 non-focal cases), generating an in situ map of localized disease programs. Four disease-associated compartments—immune/interstitial fibroblasts (IM/Fib), glomeruli, myofibroblasts, and vascular compartments—showed distinct compartment-specific signatures that correlated with patient-level histopathology. We further identified coordinated immune–fibrotic signaling associated with different histopathological classes. Within IM/Fib, the CXCR4–CD74 receptor complex co-localized with IgM⁺ cells, and lumican (LUM) co-localized with collagen I/III; both were validated by immunofluorescence and associated with fibrotic injury. These tissue-anchored signatures represent potential disease-associated molecular features with possible diagnostic relevance, and highlight the value of this foundational spatial transcriptomics map for generating testable hypotheses to be further evaluated in larger, stratified, treatment-annotated cohorts.

9.GSE315487 CD73抑制可克服前列腺癌模型中PARP抑制引起的适应性免疫抵抗

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、immune、resistance
  • 📝 描述:Contributors : Ping Xie ; Renqiang Ma ; Minghui Zhang ; Jie Fan ; Longzhen Song ; Yong Wan ; Bin ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMetastatic castration-resistant prostate cancer (mCRPC) remains a major cause of cancer-related mortality in the male population. While poly(ADP-ribose) polymeraseinhibitors (PARPi) are approved for selected mCRPC patients with homologous recombination repair (HRR) deficiencies, combinations with PD-1/PD-L1 inhibitors immunotherapy have demonstrated limited efficacy in unselected populations. To investigate the immunomodulatory effects of PARPi in an unbiased manner, we performed bulk RNA sequencing on HRR-proficient MyC-CaP cells treated with PARPi Olaparib or control vehicle. Pathway enrichment analysis revealed a marked upregulation of CD73 (NT5E), an emerging immune checkpoint ectoenzyme that generates extracellular adenosine, suggesting an adaptive mechanism that undermines PARPi efficacy and enables unwanted immunosuppression. CD73 induction by PARPi was confirmed in both human and mouse prostate cancer cell lines, with more pronounced effects in the HRR-compromised PTEN knock-out (KO) cells. Mechanistically, Olaparib-driven CD73 expression was mediated through the DNA damage-activated ATR-CHEK1-IRF1 and TGF-β1-ΑΚΤ signaling pathways. Concurrently, PARPi enhanced tumor cell immunogenicity by activating the type I interferon pathway and antigen presentation machinery. In vivo, combining Olaparib with CD73 blockade therapy delayed tumor growth, improved T-cell infiltration, and augmented antigen-specific CD8⁺ T-cell effector function across HRR-proficient and PTEN KO prostate cancer models. These findings highlight PARPi-induced CD73 upregulation as a novel resistance mechanism and support PARPi plus CD73 blockade as a promising therapeutic strategy for mCRPC, irrespective of HRR status.

10.GSE311644 癌胚 RNA 结合蛋白 IGF2BP 抑制白血病干细胞中的先天免疫信号通路 [ATAC-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:leukemia、immune、ATAC-seq
  • 📝 描述:Contributors : Irina Elcheva ; Karamveer Karamveer ; Yasin Uzun ; Alexis Morrissey ; Shaun MahonySeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensActivation of innate inflammatory signaling and tumor-specific antigen presentation in cancer cells provides a foundation for anti-cancer immunotherapies. Here, we show that Insulin-like Growth Factor 2 mRNA-Binding Proteins (IGF2BP1, IGF2BP2, and IGF2BP3), which are upregulated across various human malignancies, including acute myeloid leukemia (AML), suppress the activity of RNA-sensing pattern recognition receptors and downstream ISRE- and NF-κB-driven transcription. IGF2BPs exert a strong inhibitory effect on RIG-I signaling. This suppression is most pronounced when all three paralogs are co-expressed, particularly in embryonic-like hematoendothelial and leukemia stem cells and is at least partly mediated through IGF2BP-dependent regulation of negative regulators of immune signaling. Genetic and pharmacological inhibition of IGF2BPs activates innate immune signaling and induces MHC class I gene expression in AML, highlighting a promising strategy for RIG-I- and TLR-based cancer immunotherapies.
