Caption: Scanning electron micrograph of a wild-type zebrafish neuromast. Kinocilia (pseudo-coloured pink) and stereocilia (pseudo-coloured red) extend from the apical surface of mechanosensory hair cells, which provide a model for investigating hearing loss.

EDITOR'S CHOICE
EDITORIAL
PERSPECTIVE
A zebrafish-centric approach to antiepileptic drug development
Summary: Screening programs using zebrafish could reshape traditional approaches to antiepileptic drug discovery. Here we describe steps to develop zebrafish models that represent human epilepsies, with an emphasis on a zebrafish model of Dravet syndrome.
REVIEWS
Metabolic reprogramming in cancer: mechanistic insights from Drosophila
Summary: Recent research in fruit flies has demonstrated that tumors rewire their metabolism by using diverse strategies that involve feedback regulation, nutrient sensing, intercellular or even inter-organ interactions, yielding new molecules as potential cancer markers or drug targets.
Cell competition from development to neurodegeneration
Summary: This Review presents cell competition as an active selection mechanism, from its more established molecular pathways to the recently proposed ones in neurodegenerative diseases.
RESEARCH ARTICLES
A mechanism linking perinatal 2,3,7,8 tetrachlorodibenzo-p-dioxin exposure to lower urinary tract dysfunction in adulthood
Summary: We describe a new mechanism of benign prostate disease, initiated by fetal chemical exposure, which durably increases prostatic noradrenergic axon density and causes smooth muscle hyperactivity and urinary voiding dysfunction.
Circulating fibroblast growth factor-2 precipitates HIV nephropathy in mice
Editor's choice: We developed a new mouse model of childhood HIV-associated nephropathy (HIVAN) and showed that circulating FGF-2 precipitated HIVAN in young HIV-Tg26 mice by inducing the pERK pathway.
Comparison of the oncogenomic landscape of canine and feline hemangiosarcoma shows novel parallels with human angiosarcoma
Summary: Analysis of canine and feline hemangiosarcoma reveals many genetic similarities to human angiosarcoma, including recurrently mutated driver genes, differing mutational profiles between tissues and UV mutational signature, in some cases.
Loss of vacuolar-type H+-ATPase induces caspase-independent necrosis-like death of hair cells in zebrafish neuromasts
Summary: Vacuolar-type H+-ATPase (V-ATPase) mutations cause necrosis-like death of mechanosensory hair cells in zebrafish. This work identifies new cell-type-specific V-ATPase functions and may help understand the causes of sensorineural deafness.
Exercise, programmed cell death and exhaustion of cardiomyocyte proliferation in aging zebrafish
Summary: A zebrafish model for studying how aging and exercise affect cardiomyocyte turnover in the human heart reveals a decrease in the proliferative capacity of the heart, which is not prevented by exercise.
Respiratory dysfunction in a mouse model of spinocerebellar ataxia type 7
Summary: A mouse model of spinocerebellar ataxia type 7 (SCA7) with at least 266 CAG repeats exhibits profound breathing deficits along with respiratory motor neuron degeneration and neuroinflammation.
CRISPR/Cas9-engineered Drosophila knock-in models to study VCP diseases
Summary: We generated a collection of nine Drosophila knock-in models that mimic VCP-related diseases and revealed novel pathologies, including sex-dependent effects and laminopathies.
RESOURCE ARTICLES
Transient, flexible gene editing in zebrafish neutrophils and macrophages for determination of cell-autonomous functions
Summary: We developed new tools for lineage-specific gene editing in neutrophils or macrophages based on leukocyte-specific Cas9 expression, that can be used with injected synthetic gRNAs.
Extramedullary multiple myeloma patient-derived orthotopic xenograft with a highly altered genome: combined molecular and therapeutic studies
Summary: The generation of a patient-derived orthotopic xenograft allowed in-depth molecular and therapeutic studies in aggressive extramedullary multiple myeloma, revealing new cytogenetic aberrations, mutations, hypermethylated genome and drug responses.

PUBLISHER'S NOTE
Call for papers – In Vitro Models of Human Disease to Inform Mechanism and Drug Discovery

We invite you to submit your latest research to our upcoming special issue: In Vitro Models of Human Disease to Inform Mechanism and Drug Discovery, coordinated by DMM Editor Vivian Li (The Francis Crick Institute, London, UK), alongside Guest Editors Austin Smith (University of Exeter, UK) and Joseph Wu (Stanford University School of Medicine, USA).The deadline for submitting articles is 6 October 2025.
The Company of Biologists Workshops

For the last 15 years, our publisher, The Company of Biologists, has provided an apt environment to inspire biology and support biologists through our Workshops series. Read about the evolution of the Workshop series and revisit JEB's experience with hosting the first Global South Workshop.
Read & Publish Open Access publishing: what authors say

We have had great feedback from authors who have benefitted from our Read & Publish agreement with their institution and have been able to publish Open Access with us without paying an APC. Read what they had to say.
Fast & Fair peer review

Our sister journal Biology Open has recently launched the next phase of their Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. To learn more about BiO’s progress and future plans, read the Editorial by Daniel Gorelick, or visit the Fast & Fair peer review page.
Propose a new Workshop for 2027

We are currently seeking proposals for Workshops to be held in 2027. As one of the scientific organisers of a The Company of Biologists Workshop, your involvement will be focused on interdisciplinary, cutting-edge science and promoting new partnerships and collaborations. We focus on the logistics. Are you thinking about proposing a topic for one of our Workshops? Apply by Friday 30 May 2025.
