1.GSE312026 肉瘤中的表观遗传重塑通过调节 Hippo 通路促进 T 细胞浸润(人类)

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:T cell、epigenetic、pathway
  • 📝 描述:Contributors : Lundqvist Andreas ; Cruz De los Santos MireiaSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensImmunotherapy in osteosarcoma remains limited by insufficient T cell infiltration. Considering the importance of epigenetics in sarcomagenesis, the impact of histone modifications in shaping the immune microenvironment was investigated. Using patient-derived ex vivo spheroids and in vivo metastatic osteosarcoma models, we found that pharmacological elevation of H3K27ac by the histone deacetylase 1/3 inhibitor entinostat promotes CD8⁺ T-cell activation, cytotoxicity, and the recruitment of CD8+CD103⁺ tissue-resident memory (TRM) T cells. Mechanistically, these immune-boosting effects are triggered by a Hippo pathway switch, in which Yes-associated protein 1 (YAP1) is suppressed and vestigial-like family member 3 (VGLL3) is induced, thereby rewiring transcription. Furthermore, we identified that VGLL3/CD103 signatures predict a response to anti-PD-1 treatment in sarcoma patients, and that combining H3K27ac induction with anti-PD-1 further augments T cell-mediated killing in ex vivo autologous patient-derived spheroid models. Our findings reveal an epigenetic-Hippo-immunomodulatory axis in osteosarcoma that also extends to other sarcomas, providing a rationale for incorporating epigenetic preconditioning with immunotherapy to improve patient outcomes and pointing towards novel biomarkers for treatment guidance.

5.GSE285362 通过单细胞和空间转录组学鉴定人类卵巢皮质中的冷冻敏感微环境和可靶向的FOS/AP-1程序

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:spatial、spatial transcriptomics、transcriptomics
  • 📝 描述:Contributors : Fanghao Guo ; Di Sun ; Wen LiSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensOvary is a vital and dynamic reproductive organ. Ovarian tissue cryopreservation (OTC) plays vital role in female fertility preservation, especially for adolescent female cancer patients. Yet, the sensitive cell populations and cryoinjury molecular mechanisms underlying cryopreservation remain elusive. This study employs single-cell RNA sequencing and spatial transcriptomics to dissect the impacts of temperature stress and cryoprotectant toxicity on the human ovarian cortex. The spatiotemporal molecular characteristics of eight ovarian cell types following vitrification-thawing had been comprehensively characterized. Granulosa, perivascular and stromal cells are identified as most sensitive cell types to OTC procedure. Further analysis using Smart-seq2 on oocytes highlights alterations in “cell cycle” and “DNA methylation” pathways. Notably, the FOS/AP-1 pathway emerges as a crucial response factor to stress and toxicity during cryopreservation. Inhibition of this pathway with T-5224 mitigates vascular damage and reduces apoptosis in vitrification-thawed ovaries. These findings provide insight into the spatiotemporal dynamics during ovarian vitrification and thawing, aiding in prioritizing therapeutic strategies for pre- and post-cryopreservation interventions.

6.GSE244508 ITGB1 是一种 TNBC 肿瘤微环境依赖性免疫调节剂

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、immune、tumor microenvironment
  • 📝 描述:Contributors : Nuozi Song ; Siqi Chen ; Mingye FengSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensTumorigenesis and metastasis, as well as insufficient response and the emergence of resistance to immunotherapy, are frequently attributed to the intricate interplay between cancer cells and tumor microenvironment (TME). Cancer cells significantly contribute to the recruitment of tumor-infiltrating leukocytes, which, in turn, directly regulate cancer cell proliferation and viability. Comprehending the mechanism and key regulators of the crosstalk between cancer cells and immune components in the TME is imperative for developing efficacious immunotherapeutic interventions. Here, through an in vivo CRISPR screen targeting cell surface genes, we identify ITGB1 as a central arbiter dictating the tumorigenicity of triple-negative breast cancer (TNBC). ITGB1 mediates the establishment of pro-tumorigenic TME by orchestrating tumor-associated myeloid populations and impeding T cell infiltration, while transducing pro-survival signaling from the tumor-favorable milieu into TNBC cells, to bolster tumor development.

  • 📝 描述:Contributors : Jiaqi Zhang ; Marc A Schwartz ; Mohammed Mutaher ; Oluwatomisin Olajide ; Yuri Pritkyin ; Orr Ashenbrg ; Nir Hacohen ; Caroline UhlerSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusPerturbations of genes with functional importance in T cells could be used to change the distribution of CD8 T cell states to enhance anti-tumor functions for cancer immunotherapies. We launched a world-wide computational challenge to predict the effects of gene perturbations and to devise objective functions for prioritizing gene perturbations that lead to desired T-cell state distributions. We supported the challenge by generating a single-cell Perturb-seq dataset profiling the effect of knocking out 73 individual expert-defined genes in T cells transferred into a mouse melanoma model. We compared the top algorithms developed by participants, and found that performance was primarily determined by the prior data used for gene feature representation, with perturbational data derived features, proving most effective. Experimental validation of the top 61 genes nominated by the algorithms revealed that perturbation of Ndufv2 and Dimt1 reached the defined objective and biased differentiation toward desired states.

9. GSE325631 T调节细胞中TET功能的丧失导致前Treg细胞偏向于T滤泡辅助细胞,并通过自身抗体的产生引发自身免疫性疾病——脾脏和外周淋巴结

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:lymph、regex:lymph(o|atic)?
  • 📝 描述:Contributors : Kazumasa Suzuki ; Leo J Arteaga-Vazquez ; Bruno Villalobos Reveles ; Lot Hernández-Espinosa ; Isaac F López-Moyado ; Atsushi Odonera ; Daniela Samaniego-Castruita ; Ferhat Ay ; Arlet Lara-Custodio ; Patrick G Hogan ; Hugo Sepulveda ; Anjana RaoSeries Type : OtherOrganism : Mus musculusT regulatory cells (Treg cells) express the transcription factor FOXP3 and maintain immune homeostasis by attenuating effector responses. Treg cells are prone to lose FOXP3 and convert to pathological ‘ex-Treg’ cells under conditions of strong or chronic inflammation. One mechanism for loss of FOXP3 expression involves increased DNA methylation of intronic enhancers CNS1 and CNS2 in the Foxp3 locus; these enhancers are maintained in a demethylated state by TET enzymes, 5-methylcytosine (5mC) dioxygenases that generate 5-hydroxymethylcytosine (5hmC) and other oxidized methylcytosines that are essential intermediates in all pathways of DNA demethylation. We previously showed that FOXP3+ Treg cells from Tet2/3-deficient (Tet2/3 DKO) mice displayed increased methylation of CNS1 and CNS2 and converted to FOXP3-negative ex-Treg cells considerably more efficiently than WT Treg cells. Here we extend our previous analysis of Foxp3-Cre Tet2/3fl/fl mice. We classified the mice as DKO-moderate or DKO-severe based on the total number of leukocytes in the spleen and peripheral lymph nodes and investigated the phenotypic and molecular basis for the progressive inflammation occurring in these mice. RNA-seq as well as histological and immunocytochemical analyses showed a striking expansion of T follicular helper (Tfh) cells and plasma cells in Tet2/3 DKO-severe mice. And single-cell (sc) RNA-seq analyses suggested that this was due to skewed differentiation of both Tet2/3 DKO FOXP3+ Treg cells and Tet2/3 DKO FOXP3– ex-Treg cells into Tfh-like cells. Base-resolution “6-base” sequencing showed the expected loss of 5hmC and increased 5mC in Tfh cells purified from Tet2/3 DKO-severe mice, and suggested that the observed bias in gene expression patterns could arise either from a direct increase in methylation of essential enhancers due to TET deficiency, or from interference with binding of methylation-sensitive transcriptional repressors including CTCF.

10. GSE319803 CENPF 过表达通过 MYC 通路促进肝细胞癌细胞的 G1/S 细胞周期转换

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:carcinoma、pathway
  • 📝 描述:Contributors : Saiping Qi ; Donghu Zhou ; Sisi Chen ; Liying Sun ; Jian HuangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensCentromere protein F (CENPF), a mitosis-related protein, is overexpressed in hepatocellular carcinoma (HCC) and has emerged as a promising biomarker for early HCC. However, with ultra-large molecular weight of 358kDa of CENPF, no study has directly explored its carcinogenicity with an overexpression model. In the present study, a CRISPR/dCas9 system was applied to construct the CENPF overexpression model. CENPF was upregulated and downregulated to analyze its functions in vitro. CENPF knockdown cell models showed inhibition of HCC proliferation. Notably, as a cell cycle protein with high constitutive expression in G2/M phase, CENPF overexpression cell models also showed inhibitory effects, probably due to the toxic effect of excessive CENPF expression on G2/M transition. However, in both CENPF downregulation and overexpression models, cell cycle assays showed CENPF promoted G1/S transition in HCC cells. RNA-seq showed that CENPF overexpression activated the MYC pathway, thereby promoting G1/S transition. The rescue experiment indicated that the MYC pathway inhibitor 10058-F4 counteracted the G1/S transition induced by CENPF overexpression in HCCLM3 cells. CENPF overexpression might facilitate HCC cells G1/S cell cycle transition via the MYC pathway.
