- ✍️ 作者:未知作者
- 🏷️ 关键词:tumor、cancer、immune、aging、scRNA
- 📝 描述:Contributors : Pengze Yan ; Kornelia PolyakSeries Type : Expression profiling by high throughput sequencingOrganism : Rattus norvegicusAging is a major risk factor for breast cancer, yet how it shapes tumor development, molecular phenotype, and immune evasion remains incompletely understood. Deciphering how aging influences cancer development is critical for improving risk assessment, prevention, and treatment. Here, using a N-nitroso-N-methylurea (NMU)-induced rat mammary tumor model that recapitulates key features of human breast cancer, we integrated bulk and single-cell transcriptomics, whole-exome sequencing, and histopathological analysis to dissect age-associated differences in tumorigenesis. We found that age at NMU exposure critically influences tumor incidence, mutational burden, subtype, and immune microenvironment. Tumors arising in aged rats originate from luminal progenitor-like cells with increased genomic instability, suppressed immune infiltration, and impaired antigen presentation linked to loss of heterozygosity at Chr 20p. These age-associated epithelial and immune changes were conserved in human breast cancers, where loss of the homologous Chr 6p region correlated with reduced lymphocyte infiltration and shorter relapse-free survival. These findings reveal that aging alters the tumor-initiating cell population and promotes immune-evasive tumor states through chromosomal instability-driven antigen presentation defects. Our work provides mechanistic insight into the reduced efficacy of immunotherapy in older patients.

5. ⭐ GSE301618 RBP4 通过抑制 PI3K/AKT 信号通路和促进巨噬细胞 M1 型极化来抑制舌鳞状细胞癌的进展
- ✍️ 作者:未知作者
- 🏷️ 关键词:carcinoma、macrophage、pathway
- 📝 描述:Contributors : Ying Yan ; Nan Miao ; Xiaofeng WangSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensTongue squamous cell carcinoma (TSCC) is a common type of oral mucosal epithelial malignancy that can severely affect patient quality of life. Therefore, novel therapeutic strategies for TSCC are needed. This study aimed to investigate the role and mechanism of action of retinol-binding protein 4 (RBP4) in TSCC progression and its effect on tumor-associated macrophages. To this end, TSCC cell lines with RBP4 over-expression and knockdown were constructed, and effects of RBP4 expression on the proliferation and inva-sive abilities of TSCC cells were verified using ex vivo experiments. Furthermore, a tumor cell-macrophage co-culture model was established to assess the effect of RBP4 on macrophage polarization. RBP4 overex-pression reduced the phosphorylation of the PI3K/Akt/mTOR pathway and inhibited tumor cell proliferation by regulating Snail levels; RBP4 inhibited TSCC cells from undergoing epithelial-mesenchymal transition. In addition, RBP4 promoted the activation of NF-κB signaling pathway, leading to macrophage polarization toward M1 type and inhibiting TSCC growth. We found for the first time that RBP4 affects the prolifera-tion and migration of TSCC cells by inhibiting the activation of the PI3K-Akt signaling pathway, and that RBP4 promotes the M1-type polarization of tumor-associated macrophages, which contributes to their on-cogenic effects.

- ✍️ 作者:未知作者
- 🏷️ 关键词:cancer、immune、scRNA
- 📝 描述:Contributors : Ernesto Rojas Jimenez ; Triet Bui ; Pengze Yan ; Marco Seehawer ; Jun Nishida ; Kornelia PolyakSeries Type : Expression profiling by high throughput sequencingOrganism : Rattus norvegicusBreast cancer hormone receptor (HR) estrogen and progesterone (ER/PR) positive tumors were generated in an outbred rat model (Sprague-Dawley) through the injection of the carcinogen N-nitrosomethylurea (NMU). These tumors were treated with immune checkpoint blockade (anti PD-L1) in combination with targeted therapies, including an TBK1/IKBKE inhibitor, a KMT5B/C inhibitor, a TGF-b inhibitor, and a selective estrogen receptor degrader (SERD). This dataset includes single-cell RNA sequencing (scRNA-seq) data from tumors subjected to various treatment setups. Whole-tumor digestion was performed to preserve a comprehensive representation of the tumor microenvironment. The study aims to identify mechanisms that sensitize HR postive tumor subtypes to immune checkpoint blockade therapy.

7. ⭐ GSE315939 可扩展的单细胞总RNA测序统一了编码和非编码转录组学
- ✍️ 作者:未知作者
- 🏷️ 关键词:sequencing、single-cell、transcriptomics
- 📝 描述:Contributor : Alina IsakovaSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensCurrent single-cell RNA atlases largely capture polyadenylated transcripts while missing critical regulatory layers from non-coding RNA. To address this, we developed TotalX - a generalizable framework that adapts Smart-seq total RNA profiling for use in droplet-based platforms, and captures a broad complement of coding and non-coding RNAsusing a unified pipeline. Applying this approach to developing human brain, we generate a dataset mapping diverse RNA biotypes across all neuronal and non-neuronal lineages, revealingbiotype-specific expression programs with cell-type and temporal specificity. Tracking miRNA dynamics in Cajal–Retzius neurons, transient and early-born neurons in the cortex, we show the enrichment and target anti-correlation of MIR137, associated with schizophrenia and intellectual disability, suggesting tight regulatory control. We apply TotalX to human peripheral blood mononuclear cells and identify transcriptional modules combining coding and non-coding RNAs and tRNA dynamics. Additionally, we analyze dengue-infected hepatocytes and capture non-adenylated viral transcripts that distinguish infection states. This expanded coverage helps with understanding cellular identity and gene regulation at atlas scale

9. GSE315761 RNA-seq 分析人肠上皮 FHC 细胞中 METTL1 敲低的影响
- ✍️ 作者:未知作者
- 🏷️ 关键词:RNA-seq、regex:intestin(e|al)
- 📝 描述:Contributors : Lichao Yang ; Lianwen YuanSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensMETTL1 is a key methyltransferase responsible for N7-methylguanosine (m7G) modification of RNA and has been implicated in multiple cellular processes. However, its role in human intestinal epithelial cells remains incompletely understood. In this study, we performed RNA sequencing (RNA-seq) to characterize transcriptomic changes induced by METTL1 knockdown in human fetal intestinal epithelial (FHC) cells. Stable METTL1 knockdown was achieved using lentiviral short hairpin RNA (shRNA), while control cells were infected with a non-targeting control shRNA lentivirus (sh-Ctrl). Knockdown efficiency was validated prior to sequencing. Total RNA was extracted from METTL1-knockdown and sh-Ctrl FHC cells, with three independent biological replicates per group. This dataset provides a transcriptomic resource for investigating the regulatory role of METTL1 in intestinal epithelial cells.

1. ⭐ 注射疗法可将沉睡的肿瘤免疫细胞转化为抗癌战士。
- ✍️ 作者:未知作者
- 🏷️ 关键词:tumor、cancer、immune
- 📝 描述:KAIST researchers have developed a way to reprogram immune cells already inside tumors into cancer-killing machines. A drug injected directly into the tumor is absorbed by macrophages, prompting them to recognize and attack cancer cells while activating nearby immune defenses. This eliminates the need for lab-based cell extraction and modification. In animal models, the strategy significantly slowed tumor growth and sparked strong anticancer immune responses.
