- Rodent models in Down syndrome research: impact and future opportunities
Summary: Mouse models have boosted therapeutic options for Down syndrome, and improved models are being developed to better understand the pathophysiology of this genetic condition.
- Central and peripheral circadian clocks and their role in Alzheimer's disease
Summary: This Review summarizes how studies in Drosophila and mouse models accelerate our understanding of the links between circadian rhythm dysfunctions and age-related neurodegenerative disorders, especially Alzheimer's disease.
RESEARCH ARTICLES
- The chromatin remodeling BAP complex limits tumor-promoting activity of the Hippo pathway effector Yki to prevent neoplastic transformation in Drosophila epithelia
Summary: Using a Drosophila model of epithelial transformation, the authors identify the SWI/SNF BAP complex as an element that represses Yorkie activity and cooperates with the Yorkie protein in malignant tumor formation.
- p53-independent DUX4 pathology in cell and animal models of facioscapulohumeral muscular dystrophy
Summary: DUX4 is thought to mediate cytopathology through p53. Here, DUX4 is shown to kill primary myoblasts and promote pathological phenotypes in the iDUX4[2.7] mouse model on the p53-null background, calling into question this notion.
- Activation of the Nkx2.5–Calr–p53 signaling pathway by hyperglycemia induces cardiac remodeling and dysfunction in adult zebrafish
Summary: Induction of hyperglycemia gives rise to cardiac apoptosis and dysfunction in adult zebrafish via the Nkx2.5–Calr–p53 signaling pathway, resulting in adult cardiomyopathy.
- Adipose tissue and metabolic and inflammatory responses to stroke are altered in obese mice
Summary: Obesity, a co-morbidity for stroke, affected the acute metabolic and inflammatory response to stroke, highlighting the importance of considering comorbidities in preclinical stroke research, especially when identifying biomarkers.
- Increased acetylation of microtubules rescues human tau-induced microtubule defects and neuromuscular junction abnormalities in Drosophila
Highlighted Article: Increased acetylation of microtubules by genetic and pharmacological approaches rescues human tau overexpression-induced toxicity in Drosophila muscles and neurons.
- MMP-14 overexpression correlates with the neurodegenerative process in familial amyloidotic polyneuropathy
Summary: MMP-14 overexpression correlates with familial amyloidotic polyneuropathy disease and progression, as determined using mouse models and human samples. TTR gene silencing in the preclinical model decreases MMP-14 plasma levels.
- The Parkinson's disease-associated protein DJ-1 plays a positive nonmitochondrial role in endocytosis in Dictyostelium cells
Editor's choice: The Dictyostelium homologue of the Parkinson's disease-associated protein DJ-1 is located in the cytosol, and its loss causes cytopathological defects in endocytic and autophagic cell death pathways, but stimulates respiration by functionally normal mitochondrial respiratory complexes.

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.
Professor Elizabeth Patton appointed as DMM’s next Editor-in-Chief
We are pleased to announce that The Company of Biologists directors have appointed Professor Elizabeth Patton as DMM's new Editor-in-Chief. As Paresh Vyas writes in his Editorial, Liz ‘brings vitality and a passion for the remit of DMM, and is deeply embedded in the community.’
Did you know DMM Conference Travel Grants can be used for online meetings?
With travel restrictions still in place, we want to continue supporting early-career researchers in their careers. DMM’s Conference Travel Grants can now be used to attend virtual and online scientific meetings, workshops, conferences and training courses.
The current application round closes on 8 February 2021 – find out more.
Identification of MYOM2 as a candidate gene in hypertrophic cardiomyopathy and Tetralogy of Fallot, and its functional evaluation in the Drosophila heart
Research from Silke Sperling and colleagues uses Drosophila to identify MYOM2 as a candidate gene in congenital heart malformations in this issue’s Editor’s choice.
C. elegans as a disease model
A new Research article from Doyle et al., models spinal muscular atrophy in C. elegans to show that that targeting therapies to muscle cells is more effective than neuronal delivery. Find more research using C. elegans as a disease model in our latest subject collection.
Call for papers – The RAS Pathway: Diseases, Therapeutics and Beyond
Our upcoming special issue is now welcoming submissions until 1 April 2021. Guest-edited by Donita Brady (Perelman School of Medicine at the University of Pennsylvania, USA) and Arvin Dar (Icahn School of Medicine at Mount Sinai, USA), the issue will focus on the targeting the RAS pathway.
