  • 🏷️ 关键词:immune、sequencing、single-cell
  • 📝 描述:Contributors : Panyu Chen ; Luo ChenSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusSingle-cell RNA sequencing was performed on liver CD45+ immune cells isolated from mice subjected to acute-on-chronic liver failure (ACLF). Three experimental groups were included: CCl4-treated control mice, ACLF mice treated with vehicle, and ACLF mice treated with the EP300 inhibitor CCS1477. Male C57BL/6J mice were intraperitoneally injected with carbon tetrachloride (CCl4, 0.2 ml/kg, twice weekly) for 8 weeks. ACLF was induced by administration of a double dose of CCl4 (0.4 ml/kg), followed by intraperitoneal injection of Klebsiella pneumoniae. CCS1477 was administered intraperitoneally 2 hours before bacterial challenge. Liver CD45+ immune cells were isolated 36 hours after K. pneumoniae injection and subjected to BD Rhapsody whole-transcriptome single-cell RNA sequencing.

4.GSE279025 cGAS 缺陷小鼠表现出与染色质组织丧失、LINE1 元件去抑制和炎症诱导相关的早衰 [RNA-seq]

Cyclic GMP-AMP Synthase (cGAS) is a cytosolic DNA sensor that functions to activate interferon response upon detecting viral DNA in the cytoplasm. cGAS is also implicated in induction of inflammaging by responding to endogenous signals such as damaged DNA or LINE1 cDNA which forms in aged cells. While cGAS knockout mice are viable their aging has not been examined. Unexpectedly, we found that cGAS knockout mice exhibit accelerated aging phenotype associated with induction of inflammation and DNA damage signaling. Cells from cGAS knockout mice showed increased overall chromatin accessibility, particularly on LINE1 (L1) transposons and inflammation genes. Transcription of L1 elements was also increased associated with high levels of cytoplasmic L1 DNA and expression of ORF1 protein. Stimulated emission depletion microscopy (STED) showed that cGAS forms nuclear condensates that co-localize with heterochromatin. Taken together these results suggest a previously undescribed role for cGAS at maintaining heterochromatin and repressing L1 elements. We propose that cGAS knockout mice lose heterochromatin, leading to derepression of L1 elements and induction of inflammation resulting in premature aging phenotype.

For newly diagnosed MM (NDMM), standard three-drug treatment regimens—such as the combination of bortezomib, lenalidomide, and dexamethasone (VRd)—and the more recent inclusion of a fourth drug, anti-CD38 antibody immunotherapy, have significantly improved patient outcomes by targeting multiple mechanisms of tumorigenesis. This treatment approach typically involves several cycles of VRd induction therapy, followed by high dose melphalan (HDM) and autologous stem cell transplant (ASCT), and maintenance therapy. Treatment responses vary widely, with some patients requiring longer and more intense therapy and others exhibiting more rapid responses and longer relapse-free remission.This cycle of remission, maintenance, and eventual relapse persists despite advancements in treatment modalities, including immunotherapy, leaving MM incurable. This study characterizes the tumor state and immune microenvironment in MM patients across variable graded patient responses. Using a multimodal, longitudinal approach, we investigate immune and microenvironmental cellular changes during treatment in NDMM patients and in a second cohort of RRMM patients. For the NDMM cohort, longitudinal blood and bone marrow aspirate samples were collected at diagnosis, throughout induction therapy, following autologous stem cell transplant (ASCT), and at post-transplant intervals of 60 days, 90 days, and 1 and 2 years.

7. GSE338608 解冻后骨髓间充质干细胞(BM-MSCs)的单细胞RNA测序

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:RNA-seq、single-cell
  • 📝 描述:Contributors : Camila Medrano-Trochez ; Paramita Chatterjee ; Pallab Pradhan ; Hazel Y Stevens ; Molly E Ogle ; Edward A Botchwey ; Joanne Kurtzberg ; Carolyn Yeago ; Greg Gibson ; Krishnendu RoySeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensHuman mesenchymal stromal cells (MSCs) used in cell therapy are frequently administered directly out of thaw, yet the single-cell transcriptomic landscape of out-of-thaw MSC products is poorly defined. Here, cryopreserved bone marrow-derived MSCs from six healthy donors (seven lots) were characterized immediately after thawing using droplet-based single-cell RNA-sequencing on the Illumina-Bio-Rad ddSEQ platform. After SureCell-based UMI counting and knee filtering, profiles were analyzed with SC3 and Seurat. Donor-level clusters were identified that differ in immune-signaling, cell-surface, cell-cycle and metabolic gene programs, with low within-sample heterogeneity; cell-cycle status emerged as a major axis of inter-donor variation. Only the bone marrow samples are included in this submission.

10. GSE273874 热休克转录因子 HSF1 促进神经元基因组内拓扑异构酶 IIb (TOP2B) 的催化活性

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:Neuronal、genome
  • 📝 描述:Contributors : Lahiri Konada ; Thomas Catley ; Lance Heady ; Morgan Crewe ; Ilse D Ramirez ; Laura Wiggins ; Amir Segev ; Alice L Pyne ; Ram MadabhushiSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusTopoisomerase II (TOP2) poisons, such as etoposide and doxorubicin, are potent antineoplastic drugs that are used to treat a variety of solid tumors and leukemias. Yet these drugs also cause significant secondary malignancies and toxicity to postmitotic cells. Proliferating mammalian cells express two TOP2 isoforms, TOP2A and TOP2B, while postmitotic cells only express TOP2B. Selectively targeting TOP2A, but not TOP2B, could thus prevent secondary toxicity in postmitotic cells, but such isoform-selective targeting strategies remain elusive. Here we report that the heat shock transcription factor, HSF1, facilitates the catalytic engagement of TOP2B on chromatin. Purified recombinant HSF1 stimulates the DNA cleavage and relaxation activity of purified TOP2B. Using atomic force microscopy, we show that HSF1 also enhances the recycling of TOP2B for subsequent rounds of DNA relaxation. TOP2B co-occupies the genome with HSF1 in both postmitotic and dividing cells, and either the knockdown or inhibition of HSF1 reduces the levels of catalytically engaged TOP2B. Intriguingly, HSF1 neither significantly interacts with TOP2A nor enhances its catalytic activity. Furthermore, pharmacological HSF1 inhibitors protect postmitotic cells from the cytotoxicity of TOP2 poisons without compromising their ability to kill cancer cells, revealing a potential strategy for minimizing the side-effects of TOP2 poison-based chemotherapy.
