1.GSE327404 体内工程改造肿瘤细胞,使其成为具有全抗原谱的通用“一体化”癌症疫苗 [scRNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、cancer、vaccine、antigen、scRNA
  • 📝 描述:Series Type : Expression profiling by high throughput sequencingOrganism : Homo sapiens ; Mus musculusCancer vaccines offer a promising strategy to initiate de novo T cell responses or enhance existing ones, either functioning independently or synergizing with T cell-modulating therapeutics to reduce tumor burden. The clinical development of cancer vaccines faces challenges such as limited antigen coverage, insufficient antigen presentation, immune suppressive microenvironment, and the availability of personalized vaccines. In this study, we developed a Universal ‘all-in-one’ Cancer cell-derived Vaccine (UniCVac) with comprehensive antigen spectrum coverage by programming tumor cells into antigen-presenting cells (APCs) through the co-delivery of CIITA, NLRC5, CD80, and IL-2. This reprogramming mimics the professional APC phenotype, providing simultaneous HLA-I and HLA-II antigen presentation, co-stimulation, and T cell proliferation signals. These tumor-derived UniCVac can directly activate both CD4+ and CD8+ T cells in vitro, independent of APCs. Additionally, their co-stimulation and T cell growth-stimulating capabilities result in superior CD4+ and CD8+ T cell activation and proliferation comparable to traditional APCs, with enhanced PI3K-AKT pathways activation. Single cell transcriptome analysis confirmed the similarity in cellular subtypes between UniCVac and traditional APCs activated T cells. In mouse models, the UniCVac vaccination reprogramed the tumor microenvironment from immunosuppressive to immune-permissive, induced robust CD4+ and CD8+ T cell expansion in both preventive and therapeutic tumor models and achieved complete tumor regression in vivo. Our approach provides a platform for the development of universal cancer vaccines with full antigen spectrum coverage and the ability to directly activate both CD4+ and CD8+ T cells, offering potential combinatorial opportunities with existing T cell-based immunotherapies against cancer.

3.GSE319703 YTHDF1 作为一种非经典的核检查点,将 R 环稳态与癌症中的先天免疫抑制和适应性免疫抵抗联系起来(RNA-seq II)

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、immune、resistance、RNA-seq
  • 📝 描述:Contributors : Xiaofeng Zhu ; Shan GaoSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensInnate immune signaling within cancer cells plays an important role in shaping antitumor immunity, yet the nuclear mechanisms that restrain inappropriate immune activation remain incompletely defined. YTHDF1 is an mRNA-binding protein previously characterized as a cytoplasmic m⁶A reader. Emerging evidence indicates that YTHDF1 also functions in the nucleus, where it associates with chromatin and contributes to the regulation of R-loop homeostasis. Loss of YTHDF1 results in R-loop accumulation, genomic instability, cytosolic DNA release, and activation of the cGAS–STING–type I interferon pathway. Mechanistically, YTHDF1 interacts with the chromatin remodeler ARID1A at immune-associated genomic regions, suggesting a cooperative role in maintaining genome stability and regulating immune-related transcriptional programs. To investigate the transcriptomic and chromatin-level consequences of YTHDF1 and ARID1A perturbation, we generated RNA sequencing (RNA-seq) and R-loop CUT&Tag datasets in A549 human lung cancer cells. RNA-seq was performed in two experimental settings: (1) wild-type (WT) and YTHDF1 knockout (YTHDF1-KO) cells; and (2) WT, YTHDF1-KO, ARID1A knockdown (siARID1A), and combined YTHDF1-KO with ARID1A knockdown cells. In parallel, R-loop CUT&Tag profiling was conducted under the same respective conditions to assess genome-wide R-loop distribution. These datasets provide integrated transcriptomic and chromatin profiling resources for studying the roles of YTHDF1 and ARID1A in regulating R-loop dynamics and tumor-intrinsic innate immune signaling

7.GSE318635 肠道菌群相关色氨酸代谢产物可预防代谢功能障碍相关的脂肪肝疾病

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:metabolic、gut、regex:gut(-?microbiome)?
  • 📝 描述:Contributors : Tingting Wang ; Shuping Qiao ; Shuangya Fan ; Juan Xu ; Zhen Xu ; Chen Peng ; Junxing QuSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusAccumulating evidence suggests that the intestinal microbiota participates in the development of metabolic dysfunction-associated steatotic liver disease (MASLD) through metabolite-host interaction. However, the beneficial role of commensal mycobiota in MASLD progression remains poorly understood. Comparing the gut microbiome differences, we demonstrated that the deficiency of Caspase Recruitment Domain-containing protein 9 (CARD9), an adaptor protein for a microbiota recognition receptor, exacerbated HFD-induced MASLD in a gut fungi-dependent manner. CARD9 deficiency reduced the abundance of Saccharomyces cerevisiae (S. cerevisiae), which was a probiotic alleviating MASLD progression. S.cerevisiae promoted a significantly greater abundance of 5-hydroxyindoleacetic acid (5-HIAA) in intestine through TLR1, which then alleviated MASLD phenotypes via “gut-liver” axis. Particularly, 5-HIAA directly bond to aryl-hydrocarbon receptor (AhR) and stimulated its nuclear translocation, subsequently inducing fatty acid oxidation via carnitine palmitoyl transferase 1A (CPT1A) and acyl-CoA oxidase 1 (ACOX1) transactivation. MASLD patients exhibited decreased levels of S. cerevisiae and 5-HIAA, and S.cerevisiae effectively ameliorated hepatic steatosis and improved glucose homeostasis in patients with MASLD. In summary, our findings identified a novel pathway of fungi-S. cerevisiae stimulating intestinal 5-HIAA production and indicated that S. cerevisiae and 5-HIAA might alleviate MASLD progression, highlighting that mycobiota-dependent gut-liver axis was a promising target for the prevention of MASLD.

8.GSE308411 超级增强子介导的 SMAD3–NR2F2–ID3 转录复合物调控非小细胞肺癌中的奥希替尼耐药性 [ChIP-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、resistance、ChIP-seq
  • 📝 描述:Contributors : Aochu Liu ; Zhenguo Liu ; Lizhen Jiang ; Andong Huang ; Bingyuan Liu ; Xinqing Lin ; Shiwen Hu ; Junjun Huang ; Liyuan Yin ; Yueyuan Zheng ; Xianping ShiSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensOsimertinib resistance remains a major challenge in the treatment of non–small cell lung cancer (NSCLC). Here, we identify an unconventional super-enhancer–driven transcriptional module, composed of SMAD3, NR2F2, and ID3, in which ID3 functions as a transcriptional co-factor to sustain resistance. Mechanistically, ID3 directly interacts with SMAD3 and NR2F2, inducing conformational rearrangements that enhance their DNA-binding affinity to enhancer regions, thereby increasing transcriptional activity. This ID3-SMAD3/NR2F2 complex selectively activates EPAS1, which in turn promotes neuroendocrine differentiation and suppresses ferroptosis, thereby maintaining the resistant phenotype. Disruption of this complex abrogates EPAS1 expression and restores Osimertinib sensitivity in preclinical models. Our findings uncover a previously unrecognized role of ID3 as a transcriptional co-factor and highlight the super-enhancer–driven SMAD3–NR2F2–ID3–EPAS1 axis as a promising therapeutic target to overcome Osimertinib resistance in NSCLC.

10.GSE305504 研究发现,在 BRCA1 缺陷型乳腺癌中,PARP 抑制剂触发的肿瘤细胞固有 dsRNA 先天免疫反应因 IRF3 的抑制而受损。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、cancer、immune
  • 📝 描述:Contributors : Chu-Xia Deng ; Cuiting Zhang ; Jing-Bo ZhouSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensPoly (ADP-ribose) polymerase 1 (PARP1) inhibition represents promising targeted therapy for BRCA deficient cancer patients based on synthetic lethality theory. Recent evidence shows that efficacy of DNA damage drugs depends on two aspects, DNA repair signaling and immune response. Applying a functional proteomics approach, we find that the function of spliceosome is perturbed by PARP inhibitors via enhancing interaction between PARP1 and SF3B1, a key factor of spliceosome. We demonstrate that differential alternative spliced mRNA and accumulation of double strand RNA (dsRNA) are induced by perturbation of spliceosome upon PARP inhibitors treatment, resulting in triggering dsRNA antiviral mimicry innate immune response. Moreover, we identify a novel function of BRCA1, through which BRCA1 regulates innate immune response leading to compromising of the innate immune signaling by downregulation of IRF3 in BRCA1 deficient breast cancer cells, which reduces the sensitivity to PARP inhibitors and causes intrinsic resistance. Polyinosinic-polycytidylic acid (poly(I:C)) is a dsRNA synthetic analog sensitizing PARP inhibitors through further triggering dsRNA signaling. Finally, we show that the combination of PARP inhibitors and poly(I:C) enhances antitumor efficiency in vivo. Overall, our study reveals BRCA1 deficiency impedes tumor cell intrinsic innate immune response, inducing intrinsic resistance to PARP inhibitors that can be overcome when poly(I:C) is combined.
