1.GSE255516 通过体内 CRISPR 激活筛选肿瘤微环境调节剂,合理设计免疫基因治疗组合 [scRNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、immune、tumor microenvironment、scRNA
  • 📝 描述:Contributors : Feifei Zhang ; Ryan D Chow ; Chuanpeng Dong ; Emily He ; Lvyun Zhu ; Shan Xin ; Daniyal Mirza ; Yanzhi Feng ; Xinyu Ling ; Qin Han ; Sidi Chen ; Guangchuan WangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensThe hostile tumor microenvironment (TME) is major challenge for cancer immunotherapies. Here, we design and perform TME-targeted in vivo CRISPR activation (CRISPRa) screens to uncover factors that promote anti-tumor immunity, culminating in rationally designed immune gene therapy combinations. Through adeno-associated virus (AAV) delivery, we find that multiplexed activation of pooled immunoregulatory genes encoding antigen presentation, cytokine, and co-stimulation molecules (APCM) leads to enhanced anti-tumor immunity. A CRISPRa screen targeting APCM genes in metastatic tumors identifies CD80, TNFSF14, CXCL10, TNFSF18, TNFSF9, and IFNG as the top immunostimulatory candidates. Further optimization pinpoints 4-1BBL(TNFSF9) + IFNG + IL12B (4II) as a potent streamlined therapeutic combination. AAV delivered 4II has potent in vivo anti-tumor efficacy in multiple tumor models, by enhancing tumor antigen presentation while simultaneously promoting the infiltration, activation, and expansion of anti-tumor T cells. We further demonstrate that APCM therapy synergizes with CAR-T therapy against human solid tumors in vivo. CRISPRa screens and gene activation systems targeting APCM factors thus represent a powerful approach for rapid development of off-the-shelf immune gene therapies against solid tumors.

3.GSE230944 通过表观遗传学靶向 NPM1 促进心肌梗死后修复,重编程修复性巨噬细胞代谢 [RNA-Seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:macrophage、metabolism、cardiac、RNA-seq
  • 📝 描述:Contributors : Zhenzhen Zhan ; Sheng ZhangSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusBackground: Post-infarction heart failure is attributed to ischemia-induced myocardial inflammation and unfavorable remodeling, with reparative macrophages playing a crucial role in limiting excessive fibrosis and promoting cardiac repair via cytokine secretion and cross-cell interactions. Hence, a timely and adequate transition of macrophage phenotypes is essential for proper wound healing post-MI, but the precise mechanisms underlying this process remain incompletely elucidated. Methods: To elucidate the function of NPM1 in post-infarct cardiac repair, we generated macrophage-specific NPM1 knockout mouse models. Additionally, Cut&Tag assays were conducted on cardiac macrophages for the first time to explore the epigenetic mechanisms underlying NPM1-mediated regulation of macrophage metabolic reprogramming. Results: Macrophage-specific deletion of NPM1 in MI mouse models resulted in reduced tissue fibrosis and enhanced cardiac repair by promoting the phenotypic transition of macrophages towards a reparative state. NPM1 deletion also led to a shift in macrophage metabolism from glycolysis to mitochondrial OXPHOS via inactivation of the mTOR cascades. Mechanistically, we demonstrated that IL-4 induced NPM1 oligomerization, which recruited histone demethylase KDM5b to the promoter region of Tsc1, ultimately leading to macrophage metabolic rewiring. Antisense oligonucleotides and inhibitory compounds targeting NPM1 exhibited notable protective effects on cardiac repair post-MI. Conclusions: Our study demonstrates that NPM1 may serve as a promising prognostic biomarker and a valuable therapeutic target for ischemia-induced heart failure, shedding new light on the understanding of post-infarct cardiac repair and may pave the way for the development of innovative therapeutic strategies.

6.GSE298478 诱导肾脏发育细胞状态与预后良好型 Wilms 肿瘤的化疗耐药性相关 [RNA-seq]

  • ✍️ 作者:未知作者
  • 🏷️ 关键词:tumor、resistance、RNA-seq
  • 📝 描述:Contributors : Andrew J Murphy ; Hongjian JinSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensChildren with favorable histology Wilms tumor (FHWT) who experience disease relapse or whose tumors exhibit blastemal predominance after chemotherapy often have poor outcomes. We established a FHWT patient-derived xenograft model, KT-47, that exhibited blastemal predominance after chemotherapy treatment with vincristine, actinomycin, and doxorubicin (VAD) and ultimately developed complete resistance to VAD after serial exposures to this combination. Histologic analyses and comprehensive multi-omics approaches were used to evaluate changes associated with resistance. CUT&TAG identified increased transcriptionally active H3K4me3 at stem cell and nephrogenesis gene promoters among the most different regions in KT-47 resistant compared to the KT-47 pretreatment model including the HOXB cluster, HOXC cluster, MYCN, SIX2, IGF2, CITED1, and OSR1. In contrast, decreased H3K27me3 was identified at HOX gene cluster and nephrogenesis gene promoter regions. The most significantly upregulated transcript and protein that associated with resistance in KT-47 was the let7 microRNA processor LIN28B. LIN28B upregulation was associated with copy number gain at MYCN and plasticity of cancer cells marked by open chromatin at the LIN28B locus rather than expansion of a minor subclone expressing LIN28B present in the original primary tumor material. The stem cell-associated multidrug resistance protein ABCB1 was upregulated in epithelial cells in association with an inter-chromosomal interaction between chromosomes 1 and 7. The impact of these findings at MYCN, LIN28B, and ABCB1 were validated in additional WT models and samples. Overall, these results support de-differentiation of FHWT cancer cells to a stem-like state which is associated with chemotherapy resistance. Targeting epigenetic modifiers that modulate differentiation of cancer cells with a stem-like phenotype could be a future treatment strategy in chemotherapy resistant FHWT.

Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that help tumors grow, adapt, and survive treatment. By tracking thousands of individual cells over time, the approach shows which chromosome combinations give cancer an edge and why some tumors become especially resilient.
