Organized by eight National EV Societies under the MOVE initiative, the event gathered over 280 attendees from 28 countries, promoting collaboration and scientific exchange. The symposium featured eight keynote lectures, 48 oral and 126 poster presentations, and sessions dedicated to EV-related tools and industry innovations. The scientific program was structured around seven core themes: EV biogenesis and signal transmission, roles of EVs in health and disease, EV-based biomarkers, interspecies communication, novel EV preparation and analysis techniques, therapeutic and regenerative applications, and the manufacturing of native and engineered EV products. Supported by 18 sponsors and the Ministry of science, technological development and innovation of the Republic of Serbia, the symposium also highlighted the MOVE Fellowship Program and offered rich networking opportunities.

While the transcriptional regulation of NP genes has been extensively studied, how NPRs contribute to context-dependent behavioral plasticity remains poorly understood. Here, we investigate the genomic features and expression patterns of NPRs in Drosophila melanogaster, leveraging comparative genomics, single-cell RNA sequencing (scRNA-seq), transcription factor (TF) network analysis, and empirical validation to uncover the regulatory mechanisms that involve NPRs and play roles in context-dependent adaptation. We demonstrate that NPR genes exhibit more complex cis-regulatory landscapes, with greater numbers of enhancers compared to NP genes. Also, NPRs are regulated via a broader network of TFs, particularly in response to environmental and physiological cues such as temperature shifts. Through analysis of scRNA-seq data and qRT-PCR, we show that the expression level of NPRs is dynamically modulated in a context-dependent manner, while NP levels remain relatively stable. This \"NPR-biased\" gene regulation is evident across diverse combinations of NP-NPR pairs, with a distinct pattern of TF control in the head and body of D. melanogaster. Furthermore, the expression level of NPR genes increases during aging of the fly, suggesting a key role in aging and developmental processes.

We examined the impact of total DMD, individual transcript and dystrophin-associated protein complex (DAPC) gene expression levels on overall survival using Kaplan-Meier analysis, Cox proportional hazard modelling and pathway analysis. DMD expression was significantly associated with survival in nine cancers after Bonferroni correction (α = 0.0015), with high expression linked to either improved or worsened outcomes depending on cancer type. The most abundant DMD transcript, Dp71ab, mirrored total DMD trends, distinguishing two tumour groups with opposing survival associations. Hierarchical clustering suggests these divergent effects may be linked to a subset of signalling and adhesion-related DAPC components. Our findings indicate that DMD does not act uniformly as an oncogene or tumour suppressor. Instead, we propose a context-dependent dual model whereby high DMD expression is tumour suppressive in aggressive cancers and oncogenic in less aggressive tumours.</p>","PeriodicalId":12187,"journal":{"name":"FEBS Open Bio","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144948114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protocol describes a targeted methylation library preparation upstream short read sequencing with an Illumina instrument. The protocol includes the New England Biolabs Next Enzymatic Methyl-seq Library Preparation workflow combined with the Twist Bioscience Targeted Methylation Sequencing workflow. The protocol is divided into eight steps: fragmentation, library preparation, enzymatic conversion, indexing, pooling, hybridization, capture, and amplification. Main advantages are (a) a lower amount of DNA (100 and 50 ng) than other technologies, (b) the limitation of DNA degradation using enzymatic conversion instead of chemical bisulfite, (c) the pooling of samples into 8-plex reducing handling time, and (d) the significant reduction of the panel quantity divided by 20 for saving experimental costs. This protocol was carried out on 96 samples simultaneously in a standard molecular biology laboratory, and the multiplexing can be run up to 384 samples for methylation experiments.

Although typically associated with cell survival, autophagy has also been proposed to contribute to cell death, referred to as autophagic cell death (ACD). However, the identification of ACD remains contentious due to inconsistencies in experimental methodologies and terminological misuse. In this study, we systematically evaluated 104 research articles published in 2022 that claimed to demonstrate ACD. Articles were assessed based on established criteria, including evidence for autophagy, evidence for cell death, exclusion of apoptosis, and experimental designs demonstrating causality. Our findings reveal that only 12.5% of the articles fulfilled all ACD criteria, while 37.5% provided only correlation-level evidence. Additionally, 54.81% failed to demonstrate autophagy flux, 32.7% relied on viability loss rather than direct evidence of cell death, and 45.0% of studies utilizing autophagy inhibition failed to demonstrate actual inhibition of autophagy. Inconsistent terminology was also prevalent, with \"autophagy-mediated cell death\" often misclassified as ACD and ACD frequently misused to describe autophagy co-occurring with cell death. These issues highlight a lack of rigor in current practices, with correlation-level evidence, inappropriate experimental designs, and terminological misuse undermining study robustness. To address these challenges, we developed a systematic workflow providing experimental and analytical guidance for classifying evidence for different modes of autophagy. Our analysis underscores the need for greater rigor, standardized approaches, and precise terminology to advance understanding of the interplay between autophagy and cell death.</p>","PeriodicalId":12187,"journal":{"name":"FEBS Open Bio","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144821009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We previously demonstrated that dihydropyrimidinase-like 2A (DPYSL2A) is crucial for the monocytic differentiation of AML cells. In this study, analysis using the Comparative Toxicogenomics Database identified statins, which are well-known cholesterol-lowering drugs, as potential compounds that upregulate DPYSL2A expression in a Krüppel-like factor 4 (KLF4)-dependent manner. Most of the tested statins promoted the monocytic differentiation of non-APL AML cells, leading to rapid apoptosis. The statin-induced effects were reversed by mevalonate (MVA) supplementation, indicating dependence on MVA pathway inhibition. Furthermore, the inhibition of protein farnesylation, a downstream process of the MVA pathway, mimicked the statin-induced effects, suggesting that farnesylation suppression is essential for statin-induced KLF4/DPYSL2A expression and monocytic differentiation.
