FIRST PERSON
AT A GLANCE
- Modeling hematopoietic disorders in zebrafish
Summary: This At A Glance article and poster summarize the last 20 years of research in zebrafish models for hematopoietic disorders, highlighting how these models were created and are being applied for translational research.
REVIEW
- Experimental models and tools to tackle glioblastoma
Summary: This Review discusses preclinical modelling of glioblastoma multiforme to understand its biology and develop therapies, with a focus on mammalian model systems.
RESEARCH ARTICLES
- Sodium nitroprusside prevents the detrimental effects of glucose on the neurovascular unit and behaviour in zebrafish
Summary: Diabetes is associated with vascular and neurological impairments. The authors show that an NO donor ameliorates the glucose-exposure-induced dysfunction in the tectal neurovascular unit and whole-organism behaviour.
- Insoluble Aβ overexpression in an App knock-in mouse model alters microstructure and gamma oscillations in the prefrontal cortex, affecting anxiety-related behaviours
Summary: Aβ overexpression in a second-generation Alzheimer's disease model results in alterations in anxiety-type behaviours, as well as gamma oscillations, neural organisation and Grin2b expression in the prefrontal cortex.
- Therapeutic targeting of Notch signaling and immune checkpoint blockade in a spontaneous, genetically heterogeneous mouse model of T-cell acute lymphoblastic leukemia
Summary: Adapting a spontaneous, genetically heterogenous T-ALL model to preclinical testing demonstrated that response to therapeutic anti-Notch1 antibodies was determined by Notch1 mutational status and that PD-1 immune checkpoint blockade alone lacked anti-tumor activity.
- A new mouse model of GLUT1 deficiency syndrome exhibits abnormal sleep-wake patterns and alterations of glucose kinetics in the brain
Summary: New phenotypes are revealed by a GLUT1 deficiency mutant mouse model carrying a missense mutation in Glut1.
- Keeping Candida commensal: how lactobacilli antagonize pathogenicity of Candida albicans in an in vitro gut model
Editor's choice: Using antagonistic lactobacilli, C. albicans pathogenicity was reduced to a minimum in an in vitro gut model consisting of enterocytes and goblet cells.
- Clinical pathologies of bone fracture modelled in zebrafish
Summary: The effect of osteogenesis imperfecta, bisphosphonate treatment and bacterial infection on phases of bone fracture repair are determined using a zebrafish fracture model.

DMM and COVID-19
We are aware that the COVID-19 pandemic is having an unprecedented impact on researchers worldwide. The Editors of all The Company of Biologists’ journals have been considering ways in which we can alleviate concerns that members of our community may have around publishing activities during this time. Read about the actions we are taking at this time.
Please don’t hesitate to contact the Editorial Office if you have any questions or concerns.
Travel grants and how to use them (when there’s no travel)
“2020 may be a year of imaginary travel across Zoom backgrounds, but the science is still happening and we’re not planning on missing it.”
Read our Editorial, which explains how DMM and its publisher, The Company of Biologists, have adapted the financial support they provide in response to the ongoing pandemic.
Interviews – Shohei Yoshimoto, Patricia Shaw, Jelmer Hoeksma
First authors Shohei Yoshimoto, Patricia Shaw and Jelmer Hoeksma each take us behind the scenes of their latest papers in DMM, discussing the merits of their model systems, the implications of their work and life as an early-career researcher.

Pathological evaluation of rats carrying in-frame mutations in the dystrophin gene: a new model of Becker muscular dystrophy
In October’s Editor’s choice, Yamanouchi et al’s newly established rat model exhibits the dystrophic phenotype and abnormal dystrophin expression profile, similar to patients with Becker muscular dystrophy.
