- Spotlight on zebrafish: the next wave of translational research
Summary: Zebrafish are a highly versatile and relevant organism for human disease modelling. This Editorial highlights the recent zebrafish research published in DMM.

REVIEW
- Cardiac phenotype in mouse models of systemic autoimmunity
Summary: Cardiac complications are common in systemic autoimmunity, and mouse models are essential for mechanistic and therapeutic studies. Here, the authors present a decision framework to facilitate model choice for selected cardiac phenotypes in systemic autoimmunity.
RESEARCH ARTICLES
- Establishment of a zebrafish hematological disease model induced by 1,4-benzoquinone
Summary: Acute exposure to 1,4-benzoquinone leads to lineage-specific hematotoxicity in zebrafish from embryonic stages to adulthood, resembling benzene-induced cytopenia and myeloid dysplasia in humans.
- Individual components of the SWI/SNF chromatin remodelling complex have distinct roles in memory neurons of the Drosophila mushroom body
Summary: The SWI/SNF chromatin remodelling complex is the most over-represented protein complex in the intellectual disability. Different components of this complex have distinct roles in development and function of memory-forming neurons in the Drosophila mushroom body.
- Chronic otitis media is initiated by a bulla cavitation defect in the FBXO11 mouse model
Summary: FBXO11 is a candidate disease gene for otitis media in humans and the authors report that a bulla cavitation defect initiates otitis media in the Fbxo11Jf/+ mouse model.
- Integrative analysis of Paneth cell proteomic and transcriptomic data from intestinal organoids reveals functional processes dependent on autophagy
Editor's choice: Using an integrative approach encompassing intestinal organoid culture, proteomics, transcriptomics and protein-protein interaction networks, we list Paneth cell functions dependent on autophagy.
- The zebrafish orthologue of the human hepatocerebral disease gene MPV17 plays pleiotropic roles in mitochondria
Summary: The zebrafish mpv17−/− mutant shows a severe mitochondrial phenotype with ultrastructural alterations and oxidative phosphorylation impairment. The pyrimidine precursor orotic acid ameliorates mpv17−/− phenotype and increases mitochondrial DNA content, linking the loss of Mpv17 to pyrimidine de novo synthesis.
- Reverse genetic screen reveals that Il34 facilitates yolk sac macrophage distribution and seeding of the brain
Summary: Using a new reverse genetic screening method for zebrafish microglia development, involving automated image analysis, we identified that il34 facilitates yolk sac macrophage distribution to target organs, including the brain.
- BCL-3 promotes a cancer stem cell phenotype by enhancing β-catenin signalling in colorectal tumour cells
Summary: BCL-3 acts as a co-activator of β-catenin/TCF-mediated transcriptional activity, driving a stem-cell-like phenotype in colorectal cancer cells, with implications for tumour cell plasticity and therapeutic resistance.
- Early and late endothelial response in breast cancer metastasis in mice: simultaneous quantification of endothelial biomarkers using a mass spectrometry-based method
Summary: A microLC/MS-MRM-based approach for simultaneous determination of endothelium-related biomarkers identified glycocalyx disruption, endothelial inflammation and increased endothelial permeability as important events in early pulmonary metastasis in a murine model of breast cancer metastasis.

preLights – HSP110 dependent HSP70 disaggregation machinery mediates prion-like propagation of amyloidogenic proteins in metazoa
Highlighted by Tessa Sinnige, a recent preprint from Carmen Nussbaum-Krammer and co-workers shows that Hsp110 activity protects against amorphous protein aggregation but promotes amyloid aggregation and toxicity in C. elegans models.
