2. GSE327517 靶向 UBE2F 可诱导增强 CD8 T 细胞免疫的韧性程序

- 🏷️ 关键词:immunity、T cell
- 📝 描述:Contributor : Xiaonan MaSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusCD8 memory T cells (TMEM) and exhausted T cells (TEX) are essential for host defense against infection and cancer, yet their therapeutic potential is often limited by insufficient persistence and sustained functional capacity. Strategies to enhance the longevity of both populations remain scarce. Here, we demonstrate that ablation of UBE2F, a neddylation E2 enzyme, induces a resilience program in CD8 T cells that operates across both TMEM and TEX compartments, resulting in improved viral and tumor control. This resilience state is characterized by enhanced self-renewal and survival without perturbing the conventional CD8 T cell differentiation trajectories. Mechanistically, UBE2F deficiency inhibited neddylation of CUL5, leading to accumulation of JUNB and upregulation of IL-2Rβ. The increased IL-2Rβ expression hypersensitizes CD8 T cells to physiological IL-15, thereby conferring the resilience features. Together, these findings identify the UBE2F-CUL5-JUNB-IL-2Rβ axis as a conserved post-translational mechanism regulating CD8 T cell longevity across memory and exhausted states, providing a novel strategy for enhancing antiviral and antitumor immunity.

The transcriptome analysis revealed that YY-15 does not exert its anti-tumor effect solely through telomere dysfunction, but instead simultaneously regulates cell cycle, senescence, apoptosis, and metabolic-related signaling pathways, thereby synergistically inducing the death of ovarian cancer cells.

- 🏷️ 关键词:leukemia、metabolism
- 📝 描述:Contributors : Keren Peng ; Jianshan Mo ; Zhenjiao Yang ; Wen DingSeries Type : Expression profiling by high throughput sequencingOrganism : HomoChemotherapy resistance and intolerance pose significant challenges in the effective treatment of leukemia. Among the distinctive features associated with chemoresistance, metabolic reprogramming emerges as a key factor. In this study, we unveil a novel mechanism contributing to chemoresistance in leukemia, specifically highlighting the pivotal role of altered lipid homeostasis.We found that multiple lipid metabolism processes are aberrantly activated in Ara-C resistant AML cells, with upregulation of JAK-STAT3 signaling pathways and multiple enzymes in the process of fatty acid metabolism. A potent, and highly selective STAT3 inhibitor, W1307, was designed, and exhibited significant anti-tumor activities in vitro and in vivo. Genetic and pharmacological inhibition of STAT3 leads to inhibition of lipid synthesis and catabolism, resulting lipids metabolic disorder. Mechanistically, STAT3 binds to consensus DNA response elements in the promoters of the lipid metabolism associated genes (SREBP1, CPT2) and regulates their expression. Furthermore, inhibition of STAT3 enhances the anti-tumor effect of Ara-C and sensitizes resistant AML cell line to Ara-C through disrupting lipid homeostasis and triggering lipotoxicity. Collectively, our work illuminates the pivotal role of lipid metabolism adaptation driven by STAT3 in chemoresistance. The identification of W1307 as a promising candidate compound underscores its potential as a therapeutic intervention in leukemia treatment and overcoming chemoresistance.

5. GSE327488 雪旺细胞与 CD4+T 细胞的相互作用促进结直肠癌神经周围侵袭的进展 [RNA-seq]
- ✍️ 作者:未知作者
- 🏷️ 关键词:cancer、RNA-seq
- 📝 描述:Series Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensBackground: Perineural invasion (PNI) is a common pathological feature associated with poor prognosis of colorectal cancer (CRC). However, the mechanisms underlying PNI formation and its relationship with CD4+T cells within the tumor immune microenvironment remain unclear. Aims: This study investigated the role of CD4+T cells in the development and progression of PNI in CRC by examining the interactions between Schwann cells (SCs), primary glial cells in peripheral nerves, and CD4+T cells. Methods: Single-cell RNA sequencing, spatial transcriptomics, and multiplex immunohistochemistry were used to profile the characteristics and spatial relationship between SCs and CD4+T cells in PNI CRC tissues. This study established an SCs-CD4⁺T-cells co-culture system and used flow cytometry, transcriptomic sequencing, proteomics, and ATAC-seq to investigate the mechanisms of their interaction. The key findings were validated in mouse models of sciatic nerve invasion and subcutaneous tumor formation. Finally, the origin of PNI was explored by co-culturing SCs with CRC cells. Results: The results revealed the presence of a distinct heat shock protein family A member 6 (HSPA6)+CD4+T cell subset—CD4+Tstr cells—in CRC PNI tissues. These cells are induced by SCs, further enhancing SCs’ migration and tumor-promoting capabilities while contributing to an immunosuppressive microenvironment. Moreover, SCs in contact with tumor cells possess the ability to recruit CD4+T cells, potentially representing a key mechanism underlying PNI formation. Conclusion: This study suggests that SCs near CRC tissues recruit CD4+T cells, promote their conversion to CD4+Tstr cells, establish an immunosuppressive microenvironment, and simultaneously enhance SCs’ migration and tumor-promoting capabilities, thereby accelerating PNI development.

- 🏷️ 关键词:metabolism、methylation
- 📝 描述:Contributors : Ignacio Heras-Murillo ; Stefanie K Wculek ; Josep Calafell-Segura ; Esteban Ballestar ; David SanchoSeries Type : Methylation profiling by arrayOrganism : Mus musculusActivation of dendritic cells (DCs) is linked to increased glycolysis. However, the role of the mitochondrial electron transport chain (ETC) in conventional DC subset function is poorly defined. Here, we revealed that immunogenic activation elevates late oxygen consumption in cDC1s, but not cDC2s. To investigate the relevance of the ETC in DC immunogenicity, we generated mice with impaired ETC complex III function in DCs. ETC complex III impairment attenuated poised or adjuvant-triggered cDC1 activation, migration and capability to prime T cells for anti-cancer immunity, while it had a mild effect on cDC2s. Mechanistically, loss of complex III in cDC1s led to a deregulated redox and metabolite balance causing DNA hypermethylation of PU.1-binding regions. This DNA hypermethylation diminished early stimulus-induced gene expression linked to immunogenic responsiveness of cDC1s, which was rescued via ectopic expression of alternative oxidase. Our findings show how the ETC differentially regulates the immunogenic function of cDC subsets.

This study provides the first integrative analysis of volatile compound dynamics and transcriptomic regulations during apricot fermentation by Wickerhamomyces anomalus Using GC-MS, we tracked the temporal evolution of key aroma-active metabolites including s 3-hydroxy-2-butanone, 2,3-butanediol, benzaldehyde, isoamyl alcohol, and phenethyl alcohol across 0, 16, 32 ,48, and 64 h. these aromatic compounds exhibited a distinct accumulation pattern, peaking at 48h with concentrations of 11.14 μg/g, 1.28 μg/g, 6.13 μg/g, 29.12 μg/g, and 13.59 μg/g respectively. Metatranscriptomicprofiling revealed extensive differential gene expression at different time points of fermentation. KEGG pathway analysis revealed the mechanisms to produce 3-hydroxy-2-butanone and 2,3-butanediol, as well as the phenylalanine-dervided aromatic compounds. Gene annotation establish direct link between transcriptional regulation and volatile production, uncovering mechanistic connections between yeast metabolism and aroma development. The findings highlight W. anomalus as a promising non-conventional yeast for natural aroma enhancement, offering new biotechnological strategies to optimize flavor quality in fruit-based fermentations and functional foods.
