Cover: Immunofluorescence image of submandibular salivary glands (SMGs) in a mouse exposed to three doses of 5 Gy gamma irradiation. The image was taken 3 days after irradiation; the epithelial marker E-cadherin is shown in magenta and the water channel aquaporin 5 in green. Since radiation injury alters the epithelial architecture and vascularisation of murine SMG three radiation regimes were compared to model the salivary gland injury that occurs after radiotherapy to treat head and neck cancer. A single dose of 10 Gy is the most refined method for studying acute injury. See article by Johnson et al. (dmm050733).

EDITORIAL
Negative equity – the value of reporting negative results
Summary: Negative data are often not published or shared, despite their immense value to scientific progression. Here, we outline some initiatives that aim to encourage the dissemination of all scientific results.
REVIEWS
Understanding the interplay between dNTP metabolism and genome stability in cancer
Summary: This Review provides an overview of the current knowledge on both the causes and consequences of dNTP pool perturbations in cancer cells, together with their impact upon genome stability.
Fine-tuning AMPK in physiology and disease using point-mutant mouse models
Summary: Knock-in mouse models of AMPK target proteins deepen our understanding of AMPK biology, revealing new insights and complexities that impact related human disease.

RESEARCH ARTICLES
CCL2 signaling promotes skeletal muscle wasting in non-tumor and breast tumor models
Editor's choice: Using in vitro and in vivo models, this study identifies an important role for CCL2–CCR2 signaling in skeletal muscle wasting associated with breast cancer, with important implications for therapeutic targeting.
A genetically small fetus impairs placental adaptations near term
Summary: In a mouse model of reduced fetal growth demand, the placenta receives diminished blood flow via the umbilical artery and lowers its nutrient transfer capacity towards the end of gestation.
A deleterious variant of INTS1 leads to disrupted sleep–wake cycles
Summary: A deleterious variant of INTS1, the core subunit of the Integrator complex, causes severe sleep disturbances in humans.
Reduced connexin-43 expression, slow conduction and repolarisation dispersion in a model of hypertrophic cardiomyopathy
Summary: iPSC-derived cardiomyocytes with the MYH7 R403Q variant show conduction slowing, increased spatial dispersion of repolarization and reduced expression of some rhythmonome proteins, suggesting a biophysical basis for arrhythmia in hypertrophic cardiomyopathy.
A single dose of radiation elicits comparable acute salivary gland injury to fractionated radiation
Summary: Using three regimes of γ-irradiation, a single 10 Gy dose was found to be the most refined method of inducing acute salivary gland injury in a mouse model to study the effects of head and neck cancer radiotherapy.
Functional distinction in oncogenic Ras variant activity in Caenorhabditis elegans
Summary: This research uncovers distinct functional classes for oncogenic Ras variants in a C. elegans model, including distinctions in their response to genetic modifiers that function in neighboring cells.
Macrophages directly kill bladder cancer cells through TNF signaling as an early response to BCG therapy
Summary: The BCG vaccine induces bladder cancer clearance by recruiting and polarizing macrophages towards a pro-inflammatory state, directly inducing apoptosis through TNF signaling, adding an extra step to the BCG-induced tumor immunity model.
HBS1L deficiency causes retinal dystrophy in a child and in a mouse model associated with defective development of photoreceptor cells
Summary: Deficiency of the ribosomal rescue factor HBS1L causes retinal degeneration in both a human patient and hypomorph mice, and proteomic profiling reveals the underlying disruption of disc morphogenesis and photoreceptor cell function.
Characterization of a monkey model with experimental retinal damage induced by N-methyl-D-aspartate
Summary: Retinal damage was experimentally induced in rhesus monkeys by intravitreal injection of N-methyl-D-aspartate (NMDA). Optical coherence tomography and electroretinography examinations showed similarities with human retinal diseases.
Muscle-specific lack of Gfpt1 triggers ER stress to alleviate misfolded protein accumulation
Summary: Gfpt1 deficiency only in skeletal muscles triggers the unfolded protein response. Maladaptive unfolded protein response due to suppressed autophagy fails to eliminate protein aggregates and provokes apoptosis in skeletal muscles.
FIRST PERSON
New Special Issue: Translating Multiscale Research in Rare Disease. Edited by Monica Justice, Monkol Lek, Karen Liu and Kate Rauen.
This special issue features original Research, Resources & Methods and Review-type articles that aim to interrogate the mechanisms of rare diseases to foster meaningful clinical progress in their diagnosis and treatment.
The role of the International Society for Stem Cell Research (ISSCR) guidelines in disease modelling
The ISSCR provides comprehensive guidelines and standards for using human stem cells in biomedical research. In this Editorial, Cody Juguilon and Joseph Wu discuss how and why these should be incorporated in disease modelling research.
Subject collection: Building advocacy into research
DMM’s series - Building advocacy into research - features interviews, ‘The Patient’s Voice’, with patients and advocates for a range of disease types, with the aim of supporting the highest quality research for the benefit of all patients affected by disease.
