1.GSE326102 全基因组组蛋白乙酰化凸显了光热疗法在卵巢癌中诱导的肿瘤内在免疫信号传导

  • ✍️ 作者:未知作者

  • 📝 描述:Contributors : Reddick Walker III ; Melissa Hadley ; Jose Colina ; Kevin Nestler ; Abby Lee ; Elizabeth Sweeney ; Rohan Fernandes ; Katherine B ChiappinelliSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensOvarian cancer remains the most lethal gynecological malignancy with few durable responses to standard of care platinum-based chemotherapies and emerging immunotherapies. This poor response is attributed to the immunosuppressive tumor microenvironment which lacks effector lymphocytes necessary for tumor clearance. Therefore, increasing tumor intrinsic immune signaling remains a therapeutic goal for OC. One strategy for improved tumor intrinsic immune signaling relies on induction of tumor cell immunogenic cell death (ICD) features including tumor cell surface expression of Calreticulin and Hsp70 with concurrent release of immunostimulatory signals that activate innate and adaptive immune cells. The induction of ICD through a nanoparticle-based heat shock treatment, termed Prussian blue nanoparticle photothermal therapy (PBNP-PTT), has shown strong recruitment of antigen-specific lymphocytes to the tumor microenvironment in glioblastoma and neuroblastoma preclinical models. While the molecular signatures of ICD are well described, the epigenetic reprogramming during treatment-induced tumor intrinsic immune signaling remains unknown. Therefore, this study sought to determine the efficacy of PBNP-PTT heat shock in ovarian cancer and characterize epigenetic responses that accompany its induced tumor intrinsic immune signaling. We first demonstrate that PBNP-PTT activates tumor intrinsic immune signaling in ovarian cancer and leads to improved monocyte activation through tumor cell proinflammatory cytokine release and presentation of Calreticulin and Hsp70. Accompanying this intrinsic immunostimulatory effect, PBNP-PTT induces genome-wide chromatin accessibility via H3K9ac, which associates with chromatin remodeling and heat shock response genes. Lastly, we show targeting histone acetylation via histone deacetylase inhibition (Panobinostat) improves the tumor intrinsic immune signaling potential of PBNP-PTT. These findings indicate that PBNP-PTT activates the release of immunostimulatory factors in ovarian cancer cells through H3K9ac rewiring and suggests the potential of combination with HDACi to improve tumor intrinsic immune signaling in ovarian cancer.

  • 📝 描述:Contributors : Gloria Solano-Aguilar ; Sukla Lakshman ; Celine Chen ; Ethiopia Beshah ; Aleksey Molokin ; Bryan Vinyard ; Harry Dawson ; Monica Santin-Duran ; Gonzalo Bruna ; Allen Smith ; Joseph UrbanSeries Type : Expression profiling by high throughput sequencingOrganism : Sus scrofaDietary intake of fruits and vegetables (FV) has been inversely associated with lower risk of ulcerative colitis. A pig model was used to evaluate the impact of feeding FV on the host response to dextran sulfate sodium (DSS)-induced colitis. Methods: Six-week-old pigs were fed a grower diet alone or supplemented with lyophilized FV equivalent to the half (half-FV) or full (full-FV) daily levels recommended for humans by the Dietary Guidelines for Americans (DGA). Pigs were fed a 1) grower diet alone (negative control), 2) grower diet and orally treated with 4% DSS for 10 days to induce colitis (positive control), 3) half-FV diet treated with 4% DSS or 4) full-FV diet treated with 4% DSS. Pigs were monitored for the development of clinical signs of colitis. Proximal colon (PC) contents and mucosa (PCM) were collected for gut metagenome, tissue transcriptome and histopathological analysis. Results: Pigs fed the full-FV diet did not exhibit diarrhea, showed less fecal occult blood (FOB), PCM crypt hyperplasia but with no differential expressed genes (DEG) or changes in PC microbiome diversity (p < 0.05). Pigs within the half-FV group exhibited increased group FOB and DEG associated with tissue remodeling, crypt and goblet cell hyperplasia in the PCM and no changes in PC microbiome diversity and two pigs exhibiting diarrhea (p < 0.05). Pigs within the DSS positive control group exhibited a reduced DEG involved with intestinal immune response and PC microbiome diversity with altered metagenome, increased group PCM erosion and FOB with persistent diarrhea in one pig (p < 0.05) Conclusions: Overall, our results showed that pigs fed a three-week full-FV supplemented diet, were resistant to DSS-induced colitis with a differential dose-dependent protective effect on host intestinal tissue and gut metagenome when exposed to an inflammatory challenge.

3.GSE304150 人类黑色素瘤细胞中芳烃受体的激活增强癌细胞固有的 MHC-II 表达 [全基因组 CRISPR 筛选]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:cancer、MHC、genome
  • 📝 描述:Contributors : Yiteng Jin ; Zexian ZengSeries Type : OtherOrganism : Homo sapiensCancer immunotherapy has revolutionized patient outcomes by enhancing immune responses, with major histocompatibility complex class II (MHC-II) playing a pivotal role. While MHC-II is classically expressed by professional antigen-presenting cells (pAPCs), emerging evidence highlights its expression by cancer cells, where it correlates with enhanced immune infiltration and favorable clinical outcomes. However, the regulatory mechanisms of cancer cell-intrinsic MHC-II remain unclear. Here, using genome-wide CRISPR-Cas9 screens, we identify the aryl hydrocarbon receptor (AhR) and its nuclear translocator (ARNT) as key regulators of MHC-II expression in human melanoma cells. The expression level and ligand-dependent activity of AhR and ARNT significantly correlate with cancer cell-intrinsic MHC-II expression. Multi-omics analyses reveal that this regulation is mediated through transcriptional activation of the MHC-II transactivator, CIITA, via binding of AhR-ARNT to its second promoter, pII. Our findings uncover a previously unrecognized regulatory axis for MHC-II expression in tumors, presenting new targets for enhancing immunotherapy.

7.GSE291525 KMT2A重排儿童急性髓系白血病中RET受体酪氨酸激酶的表观遗传调控和治疗靶向机制研究

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:leukemia、kinase、epigenetic
  • 📝 描述:Contributor : Samrat Roy ChoudhurySeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensPediatric acute myeloid leukemia (pAML) driven by KMT2A gene rearrangements (KMT2A-r; 11q23 translocations) is a high-risk leukemia with limited treatment options and a poor prognosis. Previously, we reported (PMID: 38226414) that the RET receptor tyrosine kinase is epigenetically upregulated in major KMT2A-r subgroups. In this study, we utilized a synthetic drug, 8p, which serves as a dual inhibitor of RET and cyclin-dependent kinase 8 (CDK8). We conducted RNA sequencing analysis on 8p-treated KMT2A-MLLT3 fusion-positive MOLM-13 cells to profile genome-wide gene expression changes. This study enhances our understanding of the major pathways affected by the dual inhibition of RET and CDK8 in KMT2A-r AML.

9. GSE319576 催乳素受体信号传导介导β细胞表观遗传适应以促进OVOL2结合[scATAC-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:scATAC、epigenetic
  • 📝 描述:Contributors : Nelmari Ruiz-Otero ; Jin-Yong Chung ; Ronadip R BanerjeeSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculus"Maternal pancreatic β-cells undergo functional and structural changes to adapt to increased metabolic demands during pregnancy. Lactogen signaling via the prolactin receptor (PRLR) contributes to these adaptations by increasing β-cell mass, insulin transcription and glucose-stimulated insulin secretion. Lactogen-responsive tissues such as the mammary glands and some hypothalamic nuclei display gestationally induced epigenetic changes, some of which persist long after birth. We have previously found that prolactin treatment in islets regulates the expression of epigenetic modifiers. However, whether lactogen signaling in β-cells mediates epigenetic changes to regulate chromatin accessibility has not been examined. Therefore, our objective was to determine whether PRLR signaling alters chromatin accessibility of β-cells to facilitate transcriptional regulation. We identified differentially accessible regions in wild type β-cells which had 718 overrepresented motifs following prolactin treatment of murine islets. Validating this approach, these included motifs bound by established PRLR signaling effectors such as the STAT family of transcription factors (TFs). Using RNA-sequencing we identified transcriptional changes in 41 TFs whose motifs were overrepresented in DARs. These TFs included several previously linked to PRLR signaling within β-cells, including Myc, Mafb and Esr1. Importantly, we also identified several TFs not previously associated with PRLR signaling, which included OVOL2 which is often associated with epigenetic regulation. OVOL2 is a transcription factor involved in EMT inhibition and energy homeostasis with unknown roles in β-cell functions. Here, we establish that OVOL2 acts as a negative regulator of PRL-dependent effects on glucose stimulated insulin secretion and β-cell proliferation, establishing a novel regulatory pathway for PRLR signaling.

10. GSE288641 PTPMT1依赖性调节性T细胞介导对肠道致病菌的免疫耐受

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:gut、regex:gut(-?microbiome)?
  • 📝 描述:Contributors : Mauro Corrado ; David E SaninSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMitochondrial dysfunctions are emerging as key drivers of gut inflammation, colitis, and IBD, yet their role in regulating immune tolerance remains unclear. Meanwhile, pathobiont infections, such as those caused by Helicobacter species, affect nearly half the global population, with symptoms manifesting in only 20%, adding a new layer of complexity. The genetic and environmental factors that disrupt gut tolerogenic mechanisms, tipping the balance toward disease in symptomatic infections, are not fully understood. Here, we show that PTPMT1 impairs tolerance to Helicobacter via Treg cells, independently from T cell-generated Type I or Type II interferons. Without cardiolipin, Treg cells lose metabolic fitness and immunosuppressive potential, unleashing pro-inflammatory myeloid cells in the gut. As a result, PTPMT1 ΔT mice are highly vulnerable to pathobiont infections even without microbiome imbalance. Inflammation and helper T cell imbalance are conserved in Barth syndrome, linked to cardiolipin deficiency from TAFAZZIN mutations. Overall, we propose that T cell-specific PTPMT1 governs the balance between tolerance and inflammation in the gut, dictating outcomes in pathobiont infections.
