  The authors report that, in the murine liver, intermittent fasting alters the homeostatic regenerative programme. This has fundamental implications for the use of murine models to study liver regeneration and cancer and highlights through a series of solid mechanistic studies the role of FGF/Wnt signalling interactions in modulating fasted associated regeneration. It opens up further questions as to why this occurs, how this is beneficial to adapting to a fasting state, and the potential for translation.

  This is an important study that resolves a controversy about a proposed molecular linkage between the fields of mechanobiology and RNA signaling. While prior research had claimed that a specific mechanosensitive ion channel in the gut responds to a specific fecal RNA, this study provides compelling evidence that the mechanosensitive ion channel does not respond to the RNA.

  It's been widely known that the amino acid Glycine can work as a cytoprotectant and inhibit pyroptosis-associated plasma membrane rupture. However, a long-standing question has been: how does Glycine cytoprotection work? The authors observed that Glycine treatment phenocopied deficiency of NINJ1 (a recently reported cell surface molecule critical for plasma membrane rupture), and can inhibit aggregation of NINJ1. Understanding the intrinsic mechanism by which Glycine affects NINJ1 could provide a significant advance in the cell death field.

  Seipin is a multifunctional Endoplasmic Reticulum localised protein associated with seemingly unrelated human diseases. Here the authors establish a correlation between the expression of a particular mutant form of Seipin associated in humans with motor neuron disease and altered intracellular calcium dynamics and allied proteotoxic stress. The paper is noted for the clues it provides into how these cellular defects arise and for offering a plausible, but yet unproven hypothesis for the cellular pathology that may account for the human disease phenotype.

  Jneid et al find that an entomopathogenic strain of B. thuringiensis and its Cry1A toxins, which are widely used to combat lepidopteran pests, disrupt intestinal epithelial homeostasis in Drosophila-an insect that is generally considered non-suceptible. They demonstrate that the Cry1A toxins act by altering E-cadherin-based adhesion between intestinal stem cells and their new progeny. The findings carry potential implications for unintended, broad effects of B. thuringiensis in agricultural settings.

  This work, which will be of interest to scientists in the field of hematology and ubiquitin biology, identifies previously unrecognized functions and regulatory mechanisms of an E3 ubiquitin ligase during erythrocyte progenitor maintenance and differentiation. This work has the potential to reveal that the exchange of scaffold proteins of a modular E3 ligase can have an effect on cell fate and reveal a novel mechanism of E2 enzyme regulation during differentiation. However, additional work is needed to support the major claims.
