RESEARCH ARTICLES
- Whole-transcriptome splicing profiling of E7.5 mouse primary germ layers reveals frequent alternative promoter usage during mouse early embryogenesis
Summary: This study seeks to capture the alternative splicing landscape during mouse gastrulation, underlining the potential importance of alternative promoter usage in mammalian early embryogenesis.
- Separate roles for Med12 and Wnt signaling in regulation of oxytocin expression
Summary: Mediator 12, a transcriptional coactivator, greatly enhances Wnt signaling in the developing embryo. Separate from its role in Wnt signaling, Mediator 12 is required for oxytocin expression.
- Inhibition of miR-34a-5p alleviates hypoxia-reoxygenation injury by enhancing autophagy in steatotic hepatocytes
Summary: Our study establishes an in vitro model for studying H/R injury in fatty liver, and shows that MiR-34a plays an important role in worsening H/R injury, likely by suppressing autophagy in steatotic hepatocytes.
- Degradation of cyclin B is critical for nuclear division in Trypanosoma brucei
Summary: Trypanosomes do not have a spindle checkpoint but have an ability to regulate the timing of nuclear division by modulating the cyclin B protein level.
- The cross-tissue metabolic response of abalone (Haliotis midae) to functional hypoxia
Summary: We report, for the first time, a metabolic map of abalone metabolism in response to functional hypoxia, compiled from results obtained by metabolomics analysis.
- The teneurin C-terminal domain possesses nuclease activity and is apoptogenic
Summary: Teneurins are transmembrane proteins found in the developing nervous system that are related to bacterial toxins. Teneurins also have cytotoxic properties that may help regulate apoptosis or pruning.
- pH controls spermatozoa motility in the Pacific oyster (Crassostrea gigas)
Summary: Oyster sperm motility is not triggered in an acidic environment and motility is controlled by internal pH alkalinization, mediated by a Na+/H+ exchanger.
- ZFP36L2 is a cell cycle-regulated CCCH protein necessary for DNA lesion-induced S-phase arrest
Summary: ZFP36L2 is a cell cycle-regulated RNA-binding protein, the abundance of which is regulated post-translationally. This protein is especially accumulated in and critical for the survival of DNA-damaged cells.
- Adjustable delivery of pro-angiogenic FGF-2 by alginate:collagen microspheres
Summary: The development of alginate:collagen composite hydrogel microspheres of adjustable size and degradation speed is described as a new platform for delivery of pro-angiogenic FGF-2 or pro-angiogenic cells.
- A novel reporter allele for monitoring Dll4 expression within the embryonic and adult mouse
Summary: We have developed a novel reporter line, free from complicating factors associated with previous alleles, for monitoring Dll4 expression, at a cellular resolution, in the developing and adult mouse.
METHODS & TECHNIQUES
- Streamlined histone-based fluorescence lifetime imaging microscopy (FLIM) for studying chromatin organisation
Summary: A streamlined and adaptable cell imaging method for quantitative analysis of chromatin organisation in mammalian cells, and its application, reveal a new role for ATM in regulating chromatin structure.
- Establishment and long-term maintenance of primary intestinal epithelial cells cultured from the rainbow trout, Oncorhynchus mykiss
Summary: Understanding chemical uptake from the diet is difficult in live fish: we developed long-term intestinal cell cultures that enables the science and provides an alternative method.

Biology Open 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.
Future Leader Reviews launch in Biology Open
In the next phase of expanding our support for the early-career researcher community, we are launching Future Leader Reviews in Biology Open. Aimed at those in the first stages of their scientific career, they will provide an overview of a field of research from the perspective of biology's Future Leaders.
Find out more about about how to propose a Review.
Interview - Sonu Baral
First author Sonu shares the story behind her latest BiO research, what this means for the field and where her science journey is heading to next.
Do you have an idea for a Workshop?
Our Workshop programme may be on hold for now, but we are welcoming ideas for the 2022 line-up. The proposal deadline is 29 May 2020, so find out how to pitch your idea to the Workshop Committee in good time.
How to promote your research
Publishing your paper is just the start of communicating your research to the world. Some researchers feel uneasy about self-promotion, but chances are your existing network is interested in what you’re doing – you just need to tell them! Sharing your work is useful and professional. Follow our 10 tips to get started.
