    Hyaluronan is a component of the tumour extracellular matrix. Here, Chauhan et al. show that hyaluronan increases blood pressure in collagen-rich tumours by compressing vessel walls, and that reducing the level of hyaluranon with an angiotensin II inhibitor increases blood flow and drug penetrance in tumours.

    Mutations in the gene that encodes the endosomal cation/proton antiporter NHE9 are implicated in neuropsychiatric disorders. In this study, the authors screen autism-associated variants in the human population and identify specific variants of NHE9 that are characterized by a loss of function in astrocytes.

    ORMDL3has been identified as a gene associated with asthma susceptibility, but its exact role in the pathogenesis of this disease is not well known. Here, the authors propose that induction of ORMDL3 in eosinophils modulates the expression of integrins, which could contribute to a key inflammatory event in asthma.

    Magnetic stimulation is used therapeutically for neurological disorders, but its effectiveness is hindered by efficacy and safety limitations due to large device sizes. Here the authors show that sub-millimetre, micro-magnetic coils effectively stimulate hamster cochlear neurons, with minimal side effects.

    Prion protein has been suggested to bind toxic amyloid-ß oligomers. Nicollet al.demonstrate that binding to prion protein and prion protein-dependent synaptotoxicity correlate with the presence of a tubular form of amyloid-ß with a defined triple helical structure.

    The nuclear protein HMGB1 is involved in muscle fibre formation. Here, Dormoy-Raclet et al. show that during muscle cell differentiation, the RNA-binding protein HuR promotes HMGB1mRNA translation by preventing its repression by miR-1192.

    Many biological processes are oscillatory and their rhythms shift in response to external stimuli. Here Kralemann et al. present a method to describe the sensitivity of an oscillator to external influences based on non-invasive observation of the system, and use it to study cardiac–respiratory interactions in humans.

    Tissue engineering relies on the vascular compatibility of the synthesised constructs with target tissues. Here, the authors fabricate a prevascularised tissue construct of cell-laden hydrogel fibres as a framework that allows the formation of vascularised adipose and hepatic tissues.

    Changes in autophagy have been shown to modulate lifespan in lower organisms. Here, Pyo et al.show that mice globally overexpressing the autophagy protein Atg5 live longer and are leaner than normal mice, providing the first evidence that increased autophagy extends lifespan in mammals.

    Animal experiments to study the detrimental health effects of sugar usually involve far higher doses than those consumed by humans. Here, Ruff et al.show that house mice consuming comparatively low amounts of added sugar are impaired in their ability to compete for territories, reproduce and survive in a seminatural environment.

    Damaged mitochondria are removed from cells through a process called mitophagy. Here, Hoshino et al. show that the cytosolic fraction of the protein p53 inhibits mitophagy by sequestering the mitophagy regulator Parkin, leading to impaired mitochondrial integrity and cardiac function in aged or damaged mouse hearts.

    Mutations in the metalloproteinase Zmpste24 preclude prelamin A processing and cause premature ageing. Here, de la Rosaet al.create mosaic Zmpste24 mice, revealing that cell-extrinsic effects are essential for accelerated ageing caused by prelamin A accumulation and that prelamin A reduces invasiveness of cancer cells.

    Endosomal sorting is regulated by phosphatidylinositol-3-phosphate and anomalies in this process are implicated in Alzheimer’s disease. Here the authors show that deficiency of phosphatidylinositol-3-phosphate in vitroenhances the pathological trafficking and processing of amyloid precursor protein.

    The anti-diabetic drug metformin has been shown to increase lifespan of some model organisms, but results have been conflicting. Here, Martin-Montalvo et al. administer one of two doses of metformin to male mice and show that the lower dose increases healthspan and lifespan, while the higher dose is toxic.

    Surface area features of developing visual cortices are implicated in visual perception. Songet al.measure visual discrimination sensitivity in humans and find that an increase in visual cortical surface area activity is associated with improved discrimination sensitivity and degraded contextual illusions.

    Reactivation of telomerase has been implicated in human tumorigenesis. Here, somatic mutations in the TERT promoter are reported in cancers of the central nervous system, bladder, follicular cell-derived thyroid and melanoma, thus demonstrating that TERTpromoter mutations are a frequent event in human cancer.

    Calorie restriction has been shown to extend lifespan in diverse model systems, however, the mechanisms underlying this effect remain unclear. Zhang et al.show that calorie restriction changes the structure of the gut microbiota in mice, enriching for phylotypes positively correlated with lifespan.

    Energy demand in muscle is largely due to maintaining the membrane potential of muscle fibres. Jimenez et al.study the metabolic cost of maintaining the membrane potential of muscle fibres across different species of crustaceans and fishes, and find that larger fibres are metabolically cheaper to maintain.

    The malaria parasite Plasmodium falciparum utilizes thiamine for the production of essential enzymatic cofactors. Chan et al. show that inhibition of thiamine utilization with oxythiamine inhibits proliferation of P. falciparumand reduces parasite growth in a mouse model of malaria infection.

    Focal adhesion kinase (FAK) regulates angiogenesis and FAK inhibitors are currently developed as anticancer drugs. Here Kostourou and colleagues show that genetic FAK heterozygosity or low doses of a pharmacological FAK inhibitor unexpectedly increase angiogenesis and tumour growth in vitro and in vivo.

    The scavenger receptor Scara1, expressed on microglia and macrophages, binds beta amyloid aggregates. In a mouse model of Alzheimer’s disease, the authors show that Scara1deficiency is associated with reduced clearance and increased deposition of aggregates in the brain, which results in early mortality.

    Intestinal infection with adherent-invasive Escherichia coliis associated with Crohn’s disease in humans; however, its functional role remains unclear, in part due to a lack of animal models, which sustain chronic disease. Here the authors establish such a model in mice and show that it shares features with human Crohn’s disease.

    Haplotypes in CNR1, the gene encoding the cannabinoid receptor CB1, are known to influence HDL cholesterol levels. Here Feng and colleagues identify rs806371 as a novel regulatory element reducing CNR1 gene expression and as the causal allele driving the association between CNR1 and HDL cholesterol levels in humans.
