Protein corona formation on nanoparticles and the resultant effects on cellular interactions is well documented, where less is known about the fate of the corona in the cell. Here, the authors track the protein corona and nanoparticles in cells and describe the separation and different processing within different cellular compartments.
Otosclerosis is a common form of hearing loss, with an unclear genetic etiology. Here, the authors perform a genome-wide association study meta-analysis of otosclerosis identifying 27 genetic loci, pointing to genes involved in bone remodeling, skeletal disorders and transforming growth factor β signaling.
Visualizing endogenous GPCRs is challenging. Here the authors generate mice with an enzyme self-label genome-edited into the endogenous glucagon-like peptide-1 receptor locus, design fluorescent dyes for specific labelling in complex tissue, and reveal tissue-level organisation and dynamics of an endogenous class B GPCR.
Although diet modulates aging, little is known about whether and how nutrient regulates longevity. Here, the authors show that glucose-restricted diets prolong longevity through series of conserved factors, such as neuronal AMPK, neuropeptide, AdipoR, PPARα, and Δ9 desaturases by promoting membrane fluidity.
Wearable transdermal iontophoresis offers advantages for patient-comfort when deploying epidermal diseases treatments but current self-powered iontophoresis based on energy harvesters is limited in the support of efficient long-term operation therapeutic administration. Here, the authors propose a simplified wearable iontophoresis patch with a built-in Mg battery for efficient and controllable transdermal delivery.
Fluorination of solvents, useful for non-aqueous lithium-based batteries, improves the electrochemical stability but decreases the ionic conductivity. Here, the authors report a targeted functionalization of an ether solvent to balance the electrolyte ionic conductivity and oxidative stability.
Defining cis-regulatory elements is an important goal in understanding how gene expression is regulated. Here the authors show blood cell-specific gene expression is controlled by the action of thousands of differentiation stage-specific sets of cis-elements that respond to cytokine signals terminating at signaling responsive transcription factors.
In human and mouse models of Huntington’s disease, Matsushima, Pineda et al. show, using snRNAsequencing, the two axes defining identities of striatal projection neurons are multiplexed and differentially compromised, calling for distinct therapies.
Long-read sequencing is promising for the detection of structural variants (SVs), which requires algorithms with high sensitivity and precision. Here, the authors develop DeBreak, an algorithm for comprehensive and accurate SV detection in long-read sequencing data across different platforms, which outperforms other SV callers.
Gene delivery to fibroblasts for liver fibrosis treatment remains challenging. Here the authors develop a combinatorial library of ligand-tethered lipidoids via a modular synthetic method and adopt a 2-round screening strategy to identify lipidoids for potent and selective gene delivery to fibroblasts.
Feeding an increasing world population in the context of climate change is one of the grand challenges faced by our generation. Here, the authors show that external application of synthetic complementary peptides can increase the abundance of target proteins to modulate plant growth or stress resistance.
Identifying prostate cancer patients who may respond well to PARP inhibitors is important for their success in the clinic. Here, using a genome-wide CRISPR-Cas9 knockout screen, the authors identify MMS22L as a biomarker for sensitivity to PARP inhibition in BRCA1/2-proficient prostate cancer.
All-solid-state lithium batteries performance is affected by the solid electrolyte interphase (SEI) and electrically disconnected (“dead”) Li metal. Here, via operando NMR measurements, the authors quantify the Li metal in the SEI and “dead” regions using various inorganic solid-state electrolytes.
This study quantifies the scope, time scale, and physical mechanisms underlying the cascade effects of drying on heating and vice versa across the various ecosystems of the world.
Here, by sequencing viruses from individuals in multiple households, Bendall et al. find that SARS-CoV-2 transmission bottleneck does not vary between individuals infected with pre-variant lineages and those infected with highly transmissible Alpha, Delta, or Omicron variants, suggesting these tight bottlenecks will limit the spread of new mutations.
A low-cost and efficient high-temperature oxygen evolution reaction electrode is a big challenge. Here, the authors report an iron-base electrode with an in situ formed lithium ferrite for enhanced stability and catalytic activity in molten carbonate and chloride salts and achieve kiloampere-scale electrolysis.
YTHDF1 is an m6A reader that binds to methylated RNA and facilitates translation. Here the authors show that tumor intrinsic YTHDF1 promotes tumorigenesis by regulating lysosomal proteolysis of MHC-I and that YTHDF1 targeting boosts anti-tumor immunity and response to immunotherapy in preclinical cancer models.
Separation of actinides from lanthanides is very important for the safe management of nuclear waste, however still challenging due to the chemical complexity of the f-elements. Here, authors report an efficient strategy with graphene oxide membranes for ion sieving of high valent actinyl ions and spherical lanthanide ions.
