  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、immune、sequencing
  • 📝 描述:Series Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensA comprehensive characterization of immune cells within the tumor microenvironment (TME) of cervical squamous cell carcinoma (CSCC) is essential to advance understanding of tumor biology and guide immunotherapy development. Using single-cell RNA sequencing, we analyzed 14,441 immune cells isolated from tumor tissues and paratumor tissues of three CSCC patients. This analysis identified nine major immune cell subsets, including CD8+ T cells, regulatory T cells (Tregs), natural killer/T cells (NK/T cells), B cells, plasmacytoid dendritic cells (pDCs), and macrophages. Notably, elevated CCR7 expression in exhausted CD8+ T cells was associated with improved prognosis, suggesting it as a preliminary candidate for an immunoregulatory target that warrants further investigation. Additionally, CCL5 levels were elevated in Tregs, indicating a possible involvement in their recruitment to the tumor site that requires further validation. By integrating data on tumor suppressors, oncogenic factors, cytokines, and chemokines, we performed differential gene expression analyses across immune populations, identifying candidate genes for further mechanistic investigation. This systematic comparison of the TME between tumor and paratumor tissues reveals dynamic changes in the immune landscape, providing insights and suggesting potential targets for further study to enhance understanding and treatment of CSCC.

Therefore, an in-depth study of the stemness characteristics and maintenance mechanism of GCSCs is of great significance for the treatment of gastric cancer (GC). In this study, GCSCs and non-gastric cancer stem cells (Non-GCSCs) derived from tumor tissues of GC patients were used for whole transcriptome sequencing. The goal of identifying key differentially expressed circRNAs, lncRNAs, miRNAs and mRNAs associated with GCSCs. In conclusion, we mapped the molecular feathers at RNA level closely related to GCSCs and revealed certain ncRNAs with great research potentia based on the whole transcriptome sequencing.

  • 📝 描述:Contributors : Xiangxiang Xu ; Lu Diao ; Ao Zhu ; Jin Wang ; Yuhan Liu ; Xianlan Chen ; Yan Zheng ; Jun Zhao ; Mi LiuSeries Type : OtherOrganism : Mus musculusThe therapeutic efficacy of cancer vaccines can be optimized from 3 aspects: adjuvants, vaccine formulation, and processing of tumor antigens. Herein, various different adjuvants, such as toll like receptors and STING agonists etc., and their combinations were compared in cancer nanovaccines loaded with whole tumor antigens were illustrated. By comparing different sized nanovaccines and micronvaccines, 200nm-400nm and 2.5μm were discovered to be optimal sizes of nanovaccines and micronvaccines. Rapid freezing, fixation, heating, salting-out, ethanol precipitate can affect the immunogenicity of tumor antigens and efficacy of cancer vaccines. The optimal cancer vaccine can cure all or most tumor-bearing body in melanoma mouse model, lung cancer mouse model, subcutaneous pancreatic cancer model, orthotopic pancreatic cancer model, melanoma lung metastasis model. In addition, the immune cell profiles were systematically investigated using single-cell sequencing, in blood, splenocytes and draining lymph nodes of healthy mice, PBS treated tumor-bearing mice, vaccine-treated non-cured mice and cured mice after different time. By comparing 21 samples, some featured clusters and markers, such as S100A4, KLRG1, SIPR5, CXCR3, IL2Ra, IKZF2, CX3CR1, S100A8, and S100A9 etc., were identified to distinguish responders and non-responders to immunotherapy. These biomarkers were verified and confirmed the feasibility of predicting therapeutic efficacy in mouse cancer model and cancer patients. In summary, this study presented a method to optimize cancer nanovacines from different aspects, systematically investigated immune cell profiles in non-responders and responders to immunotherapy, and discovered some featured biomarkers for predicting or distinguishing responders and non-responders to immunotherapy.

6. GSE307857 BRG1 缺失在肺癌中很常见,并通过转录和表观遗传重编程改变肺上皮细胞。

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、epigenetic
  • 📝 描述:Contributors : Mathewos Tessema ; Christin M Yingling ; Loryn M Phillips ; Kieu Do ; Maria A Picchi ; Randy Willink ; Steven A BelinskySeries Type : Methylation profiling by genome tiling arrayOrganism : Homo sapiensBackground/Objectives: BRG1 loss-of-function (LOF) mutation is found in ~10% non-small cell lung cancer (NSCLC) but its role in lung tumorigenesis is unclear and investigated in this study. Methods: BRG1-knockout (KO) lines were generated from various non-malignant, pre-malignant, and malignant human lung epithelia-derived cell lines using CRISPR. Effects of BRG1-KO on cell growth, transcriptome, methylome, and epigenetic therapy were compared with wild-type (BRG1-WT) isogenic controls using standard in vitro and in vivo assays. Results: BRG1 protein was expressed in all non/pre-malignant lung epithelial cells but lost in 47% (14/30) of NSCLC cell lines. BRG1-KO and cigarette smoke (CS) exposure individually transformed human bronchial epithelial cell lines (HBECs) as evident by anchorage-independent growth. BRG1-KO and CS produced additive to synergistic effects on sensitivity to transformation that differed across HBECs. RNA-seq analysis revealed BRG1-KO significantly changed expression of over 8,500 genes on average impacting lung development, function, damage repair and cancer pathways including axonal guidance, pulmonary wound healing, and epithelial-to-mesenchymal transition (EMT). BRG1-KO also led to hypermethylation of >47,000 promoter CpGs within ~9,500 genes on average in different HBECs that included silencing of epithelial genes involved in EMT and tumor suppressor genes. BRG1-KO also moderately increased the in vitro and in vivo sensitivity of NSCLC cells to some epigenetic drugs. Conclusion: BRG1-LOF is frequent in NSCLC, can drive transformation of lung epithelial cells to acquire properties of premalignant cells indicating a potential role in lung cancer initiation, and sensitizes lung tumors to epigenetic therapy.

8. GSE301405 DNA甲基化紊乱导致ATRT中可靶向转录可塑性[RNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:RNA-seq、methylation
  • 📝 描述:Contributors : Michael A. Koldobskiy ; Ashley R. TetensSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensAtypical teratoid rhabdoid tumor (ATRT) is a highly aggressive but genetically simple pediatric central nervous system tumor, defined by biallelic inactivation of the chromatin regulator SMARCB1 with remarkably few other cooperating mutations. Despite its genetic homogeneity, ATRT exhibits profound clinical and epigenetic heterogeneity, with three major subgroups (ATRT-TYR, ATRT-MYC, and ATRT-SHH) defined by DNA methylation and transcriptional signatures. Beyond these subgroup-defining features, we aimed to investigate epigenetic variability within tumors by applying whole-genome bisulfite sequencing and probabilistic modeling to quantify stochastic DNA methylation in primary ATRT samples encompassing all three subgroups. We show that ATRT exhibits a destabilized and increasingly stochastic methylome. While ATRT global methylation patterns diverge according to subgroup, some methylation perturbations, such as hypermethylation and increased methylation entropy over bivalent promoters, are consistent across subgroups. We find that methylation stochasticity alterations map onto potential drivers of ATRT, such as LIN28a, the HOXD cluster for ATRT-MYC, and OTX2 for ATRT-TYR, and identify actionable targets, such as hypermethylation of the tumor suppressor CDKN2a across all subgroups. We investigate the sensitivity of the aberrant DNA methylation landscape of ATRT to pharmacologic DNA methyltransferase inhibition and histone deacetylase inhibition (HDACi). We show that decitabine leads to profound demethylation of patient-derived ATRT cell lines, including reversal of hypermethylation at bivalent promoters and the CDKN2a locus. The addition of HDACi leads to dramatic gene expression changes, including upregulation of innate immune signaling pathways, such as STING/interferon signaling, genes under the regulation of bivalent promoters, and reactivation of the tumor suppressor CDKN2A. The combination of DNMTi and HDACi synergistically reduces cell viability. Taken together, we show that ATRT has a highly stochastic methylome sensitive to epigenetic manipulation.

10. GSE295777 转录因子 Yin-Yang 1 调控心脏代谢重编程以应对运动或病理应激

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:metabolic、cardiac
  • 📝 描述:Contributors : Manling Zhang ; Zishan Peng ; Haiqing Ping ; Zoe Li ; Jia-Jun Liu ; Silvia Liu ; Ning FengSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusThe pleiotropic transcription factor Yin Yang 1 (YY1) regulates cellular metabolism in a stage- and tissue-dependent manner. However, its role in cardiac energetic regulation remains unclear. We found that cardiac-specific YY1 knockout (cYY1 KO) mice exhibited cardiac dysfunction after two weeks of swimming exercise, suggesting an impaired adaptive cardiac response. Further analysis revealed that exercise-induced upregulation of transcription factor networks controlling cardiac metabolism, including peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α), was blunted in cYY1 KO mice. Consistently, citrate synthase activity, an indicator of mitochondrial content, was reduced in these mice. In response to transaortic constriction (TAC), cYY1 KO mice developed significantly exacerbated heart failure. RNA sequencing showed downregulation of metabolic genes and pathways, including PGC-1α, in TAC cYY1 KO mice hearts. Additionally, mitochondrial complex protein levels and complex I activity were reduced, consistent with suppressed metabolic gene transcription. Previously, we observed increased YY1 expression in hearts subjected to both exercise and TAC. However, while cardiac metabolism was enhanced with exercise, it was impaired with TAC. We found that p300 binding to YY1 increased during exercise, whereas histone deacetylase 3 (HDAC3) binding to YY1 increased in TAC hearts. These findings suggest that YY1-mediated transcriptional regulation of metabolic genes is modulated by the epigenetic regulators p300 and HDAC3.
