  • 📝 描述:Contributors : Baicheng Kuang ; Jimeng Ruan ; Hao Yan ; Shiqi Gu ; Tongwen Ou ; Nianqiao GongSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusIslet transplantation is an ideal option for diabetes while early graft lose serves as a major obstacle. Human umbilical cord mesenchymal stem cells (hucMSC) have multiple functions including the maintenance of cellular homeostasis. However, it is unknown whether extracellular vesicles (EVs) derived from hucMSC (hucMSC-EVs) provide protective effects against transplant-related trauma-induced islet injury. Here, we isolated and purified hucMSC-EVs, and found that hucMSC-EVs promoted grafted islet survival, and enhanced glycemic control following co-transplantation in a syngeneic streptozotocin (STZ)-induced mouse model of diabetes. After co-cultured for 12 h or 24 h, labelled hucMSC-EVs with PKH67 were readily internalized by NIT-1 β cells and islets. In tunicamycin (Tm) and thapsigargin (Tg) induced specific endoplasmic reticulum stress (ERS) cell injury models, hucMSC-EVs treatment improved cell viability and β cells function both in NIT-1 cells and ex vivo primary islets. Bulk RNA-seq demonstrated that hucMSC-EVs treatment significantly involved in ERS and the negative regulated mitochondrial apoptotic pathway. While ERS promoted interactions between endoplasmic reticulum (ER) and mitochondria, hucMSC-EVs alleviated ERS, maintained calcium homeostasis, and improved mitochondrial energy metabolism. Notably, the downregulation of XBP1 by hucMSC-EVs fine-tuned ER-mitochondria communication via reducing inositol-1,4,5-trisphosphate receptors at mitochondria-associated membranes (MAMs). Reduced XBP1 also activated Nrf2, restoring mitochondrial calcium homeostasis under ERS. miRNA analysis identified miR-182-5p enriched in hucMSC-EVs that specifically targeted XBP1 mRNA, leading to its degradation and downregulation. These findings demonstrate that hucMSC-EVs protect grafted islets by blocking XBP1 and restoring calcium homeostasis, thus suggesting their potential as a cell-free therapy for improving islet transplantation outcomes.

  • 📝 描述:Series Type : Expression profiling by high throughput sequencingOrganism : Glycine sojaSeed development is pivotal in soybean’s lifecycle, directly determining yield and nutritional quality related to oil and protein contents. However, spatiotemporally resolved mechanisms underlying cell differentiation and nutrient accumulation during seed growth remain elusive, especially in wild soybean (Glycine soja Sieb. et Zucc.), which harbors rich genetic diversity for quality traits. Here, spatial transcriptomics and metabolomics were combined to dissect their dynamics in G. soja seeds at the mid-maturity stage. Differential expression analysis characterized the distinct accumulation patterns between adaxial and abaxial embryo parenchyma cells, revealing abaxial cells are enriched in protein metabolism pathways while adaxial cells focus on lipid metabolism pathways, which is consistent with previous studies reporting spatial nutrient accumulation in G. soja seeds. Meanwhile, pseudotemporal trajectory analyses briefly supported a sequential transcriptional regulation pattern for these differences. Cell-cell communication analysis further uncovered potential signaling interactions mediating cell-type-specific differences across seed cells. Key genetic regulators and differential metabolites were identified through spatial transcriptomics and metabolomics co-expression analysis, with GsMAPK23-4 screened as a core candidate linked to cotyledon nutrient metabolism. Functional validation confirmed GsMAPK23-4 modulates seed quality: knockout mutants had significantly higher amino acids and proteins. These findings elucidate the cellular characteristics and differentiation processes in G. soja seeds at the mid-maturity stage, providing a molecular basis for understanding this phase and generating targets to improve soybean yield and quality.

  • 📝 描述:Contributors : Xiang Y Wang ; Ting wang ; Si M Zhao ; Zi G DongSeries Type : OtherOrganism : Homo sapiensNeoadjuvant chemotherapy (NACT) is a pivotal treatment strategy for esophageal cancer, significantly improving patient prognosis and 5-year survival rates. However, a substantial proportion of patients exhibit resistance to NACT and consequently fail to benefit from it. As NACT responsiveness is influenced by multiple distinct molecular pathways, it is essential to systematically investigate the mechanisms underlying poor therapeutic responses. In this study, we found that YTHDF3 directly enhances the m6A-dependent translation of key mitotic regulators, CDCA8 and INCENP, thereby reducing cellular sensitivity to NACT.

Although they are exposed to shear stress during circulation, the role of mechanical stimulation in regulating HSCs remains unknown. Piezo1, a mechanosensory ion channel, was implicated in regulation of haematopoietic cells. We analysed the transcriptional heterogeneity of LSK cells from mice treated with the Piezo1 agonist Yoda1 for 2 weeks. Our study demonstrated that activation of Piezo1 promoted HSC proliferation and differentiation toward the myeloid lineage, as evidenced by an increase in HSC numbers and the upregulation of myeloid transcription factors.

As the resident immune cells of the CNS, microglia play a crucial role in regulating perioperative inflammation and maintaining homeostasis. However, the contribution, phenotypic heterogeneity, and communication network of perioperative microglia in the development of PNCI remain insufficiently characterized. In this study, 18-month-old mice underwent surgery and developed PNCI. Single-cell RNA sequencing was performed, which identified eight microglial subpopulations and six astrocytic subpopulations in hippocampus. Postoperatively, the percentage of microglial subpopulations underwent dramatic changes, with inflammation associated microglia (IAM) increasing more than 14-fold and transition state microglia (TSM) increasing more than 33-fold. These alterations were accompanied by a marked enhancement of intercellular communications among glial cells, particularly driven by the activation of TNF signaling pathway in IAM. This pathway, along with its associated regulatory network, critically modulated the function of astrocytes and endothelial cells, thereby playing a pivotal role in CNS inflammation and the subsequent development of PNCI. Notably, administration of TNF inhibitor etanercept attenuated IAM activation and glial network communication in the hippocampus, which was associated with improved cognitive performance in PNCI mice.

The formation and roles of iBALTs related to severe asthma, however, remain unclear. iBALTs was located near the area of bronchi and vessels in the severe asthma murine model induced by house dust mite (HDM) extract and lipopolysaccharides (LPS). Repeated sensitizations promoted the formation of iBALTs, which disappeared 2 weeks post last HDM challenge. The neutralizing antibody of CXCL13 prevented the formation of iBALTs but failed to relieve the airway inflammation. B lymphocytes dominated in iBALTs. Compared with the control group, severe asthma group had increased IgE secreting cells. Bulk RNA-seq reveled the elevated MMP-12 in pulmonary B cells. MMP408, a specific MMP-12 inhibitor, reduced iBALTs formation. Moreover, AAV-6 targeting down MMP-12 in B lymphocytes blocked iBALTs and ameliorated the inflammation. These results indicated that MMP-12 from B lymphocytes motivated the aggregation of B lymphocytes, promoted the formation of iBALTs and further sharpened the inflammation of severe asthma.

Extracellular vesicles (EVs) have emerged as potential candidates for new biomarker discovery related to their protein and nucleic acid cargo.Objective: To study prothrombotic activity, cellular origin and transcriptomic profile of circulating EVs and to assess them as prognostic and therapeutic targets in PAD.Methods and Results: This prospective study included control and PAD patients. Coagulation time (Procoag-PPL kit), EVs cellular origin and phosphatidylserine exposure were determined by flow cytometry in platelet-free plasma (n=45 PAD). Transcriptomic profiles of medium/large EVs were generated using the MARS-Seq RNA-Seq protocol (n=12/group). The serum concentration of the differentially expressed gene calprotectin was validated by ELISA in control (n=100) and PAD patients (n=317). Calprotectin was also determined in EVs and tissues of human atherosclerotic plaques (n=3). Circulating EVs of PAD patients were mainly of platelet origin, predominantly AnnexinV positive and were associated with the procoagulant activity of platelet-free plasma. Transcriptomic analysis of EVs identified 15 differentially expressed genes. Among them, serum calprotectin was elevated in PAD patients (pConclusions: We found that PAD patients release EVs, mainly of platelet origin, highly positive for AnnexinV and rich in transcripts related to platelet biology and immune responses. Amputation risk prediction improved with calprotectin and was significantly higher when combined with hs-CRP. Our results suggest that EVs can be a promising component of liquid biopsy with prognostic implications in PAD.
