Most SNPs are located in non-coding genomic regions and their function remains elusive. Here, the authors perform a genome-wide scan of expression and DNA methylation quantitative trait loci in human hippocampal tissue to provide a resource for the functional interpretation of SNPs in brain disorders.
The efficiencies of materials-based catalysts are determined by the surface atomic and electronic structures, but harnessing this relationship can be challenging. Here, by engineering strain into cobalt oxide, the authors transform a once poor hydrogen evolution catalyst into one that is competitive with the state of the art.
Spondyloarthritis is an inflammatory disease with Th17 cells implicated in the pathogenesis. Here the authors show that patients with spondyloarthritis have increased numbers of GM-CSF-secreting blood and synovial lymphocytes, Th17 or not, that carry a unique transcriptional profile including enhanced GPR65 expression.
Polyketides are secondary metabolites mainly found in aerobic organisms with wide applications in medicine and agriculture. Here, the authors uncover new polyketides native to the anaerobic bacterium Clostridium acetobutylicum and show their role in triggering sporulation and granulose accumulation.
Epithelial-to-mesenchymal transition (EMT) regulates both processes of organism development and changes in cell state causing disease. Here, the authors show that an E3 ubiquitin ligase, FBXO32, regulates EMT via CtBP1 and the transcriptional program, and also mediates cancer metastatic burden and neurogenesis.
Radio observations of the solar atmosphere provide a unique view on the non-thermal processes in the outer atmosphere. Here the authors use LOFAR observations to demonstrate that the observed radio burst characteristics are dominated by propagation effects rather than underlying emission variations.
Haematopoiesis and the generation of lymphoid cell subsets are controlled by delicate genetic programs enforced via epigenetic regulation. Here the authors show that Pcid2 interacts with ZNHIT1, a component of the SRCAP chromatin remodelling complex, to critically modulate the differentiation of multipotent progenitors.
Lanthipeptides are a class of cyclic post-translationally modified peptides with potential drug-like properties. Here the authors develop a phage display system by expressing lanthipeptide precursors as C-terminal fusions to the phage M13 coat protein pIII in E. coli along with the heterologous modifying enzymes.
IP3 receptors mediate Ca2+ release from the endoplasmic reticulum. Here the authors show that only a small fraction of IP3 receptors initiate Ca2+ signals; these immobile IP3 receptors adjacent to the plasma membrane are optimally placed to control STIM1-dependent Ca2+ entry.
HIV infection results in elevated beta-amyloid (Aβ) levels in the brain, but the underlying mechanisms are unclear. Here, the authors show that amyloid precursor protein inhibits virion production and that HIV Gag, counteracting this antiviral function, results in secretase-dependent Aβ production and neuron degeneration.
tRNA-dependent cysteine biosynthesis is catalyzed by the transsulfursome protein complex. Here, the authors use a multidisciplinary approach to structurally characterize the archaeal transsulfursome and propose a model for tRNA channeling in the complex.
Polo-like kinase 1 (Plk1) is a key regulator of mitosis. Here, the authors show that Plk1 activates the pentose phosphate pathway in cancer cells by directly phosphorylating glucose-6-phosphate dehydrogenase (G6PD) and that such activation is critical for cell cycle progression and cancer cell growth.
Sirtuins are NAD+-dependent protein lysine deacylases that act as metabolic regulators and are linked to aging-related diseases. Here the authors present the Sirt4 crystal structure and show that the enzyme has dehydroxymethylglutarylation activity and is regulated by NADH.
Cell fusion regulates several physiological events, for example, fusion of myoblasts in skeletal muscle formation, but it is unclear if this process occurs in the heart. Here, the authors use transgenic reporters in zebrafish to show transient cardiomyocyte fusion, modulating cardiac development and function.
PTEN is often lost in prostate cancer. In this study, the authors show that PTEN can act as a protein phosphatase that targets active PTK6, thereby regulating its oncogenic signaling in prostate cancer progression.
Collective epithelial behaviours are studied in vitro in the context of flat sheets but a system to mimic tubular systems is lacking. Here, the authors develop a method to study collective behaviour in lumenal structures and show that several features depend on the extent of tubular confinement and/or curvature.
Little is known about Marinimicrobia, a group of bacteria that are prevalent in the oceans. Here, the authors study global populations of Marinimicrobia using single-cell genomics, metagenomics and metatranscriptomics, showing potential co-metabolic interactions and participation in the sulfur and nitrogen cycles.
Osteoclasts are involved in arthritis, and their differentiation depends on RANKL signaling. The author show that the ROS-scavenging protein DJ-1 negatively regulates RANKL signaling and that its ablation increases osteoclast numbers and exacerbates bone damage in mouse models of arthritis.
Collective self-organized behavior can be observed in a variety of systems such as colloids and microswimmers. Here O’Keeffe et al. propose a model of oscillators which move in space and tend to synchronize with neighboring oscillators and outline five types of collective self-organized states.
