Resistance to cetuximab is a common feature of colorectal cancer progression. Here, the authors utilize longitudinal proteomic profiling of 147 colorectal cancer patients and find potential biomarkers which can predict treatment response.
This study identifies potential aggregation hotspots on the fibril surface of Alzheimer’s disease associated Aβ42 fibrils, which are blocked by the anti-amyloid chaperone-like domain BRICHOS.
Wang et al. profile age-dependent miRNAomic changes in worm tissues and extracellular vesicles (EVs). They show that ageing controls miRNAs in a tissue-specific manner and their findings further suggest a complex EV-mediated miRNA trafficking network across tissues.
Mitotic spindle assembles in each blastomere to segregate duplicated chromosomes during cleavage of the fertilized egg. Here, the authors establish functional assays in fish embryos and find that Ran-GTP assembles a microtubule network at the metaphase spindle center that is essential for chromosome segregation.
Dressings for aiding in chronic wound healing can be beneficial, but often involve additional processes or leave residue. Here, the authors report a hydrogel dressing with antibiofilm and antioxidative properties for the treatment of infected diabetic wounds.
Preclinical studies have suggested the synergistic effect of epigenetic modulators and immunotherapy. Here the authors report the results of a phase Ib/II trial of durvalumab and guadecitabine in advanced clear cell renal cell carcinoma.
The human brain is highly asymmetrical and increasingly so with age. Here the authors examine hemispheric brain age estimates, which provide additional insights into brain asymmetries.
Congenital heart disease is life threatening, and its screening is complex and costly. Here, authors use AI to detect the disease based on pediatric electrocardiogram, suggesting superior performance over cardiologists.
Replication stress represents a major threat to genome integrity of normal and cancer cells. Here, the authors find that the long non-coding RNA lncREST affects the replication stress response through interaction with nucleolin. This interaction bridges the recruitment of replication factors to stressed chromatin.
Ceramide, a central molecule in sphingolipid metabolism, has been shown to affect the development and functionality of myeloid cells. Here the authors report that myeloid deficiency of neutral ceramidase (NcDase), the enzyme converting ceramide into sphingosine, induces an immunosuppressive phenotype of tumor associated macrophages, linked to T cell exhaustion in breast cancer preclinical models.
CRISPR-based gene drives have the potential to spread within populations and are considered as promising vector control tools. Here the authors show an anti-drive mosquito strain that prevents the spread and collapse of a population suppression gene drive in laboratory Anopheles mosquito large cage trials in complex ecological and behavioral conditions.
The glutamate transporter GLAST in astrocyte regulates synapse function by glutamate clearance. Here, the authors show that Down syndrome cell adhesion molecule (DSCAM) in Purkinje cells controls synaptogenesis through the intercellular association with GLAST in the developing cerebellum.
Argonaute proteins are loaded with small RNAs to confer target RNA specificity and proper gene silencing. Here, the authors establish that HRDE-2 recruits the unloaded nuclear Argonaute HRDE-1 to germ granules to facilitate correct small RNA loading.
Photoredox catalysis is an important approach for synthesizing fine chemicals from olefins, but the limited lifetime of radical cation intermediates severely restricts the efficiency. Here, the authors report that Ag3PO4 can efficiently catalyze intramolecular and intermolecular [2 + 2] and Diels–Alder cycloadditions under visible-light irradiation.
Dysregulation of alternative polyadenylation (APA) is associated with poor prognosis in cancer but its functional role is less clear. Here, the authors develop a CRISPR-Cas9- based screen to determine the effects of different APA events on melanoma growth in mouse models.
Plant cell-surface receptors perceive both self- and nonself-molecules to regulate biological processes. Here the authors show that a subclass of phytohormone and immune receptors share a common origin, which have diverged to perceive distinct ligands and activate differential downstream responses.
The authors found that replacing animal source foods with plant-based alternatives would lead to substantial reductions in environmental impacts, while meeting most nutrition recommendations and being cost-competitive with the current average Swedish diet.
Nanoreactors, with biomimetic features and distinct catalytic functions, show promise in catalytic energy conversion. Here the authors propose the utilization of precisely engineered mesoporous carbon spheres with tunable hollow sizes as nanoreactors, leveraging their catalytic functionalities for enhanced diffusion and microenvironment modulation effects to achieve efficient hydrogen peroxide electrosynthesis.
Exceptional points emerge in systems with loss and gain when loss and gain in the system are balanced. Due to the careful balancing involved, they are highly sensitive to perturbations, making them exceptionally useful for sensors and other devices. Here, Wittrock et al observe a variety of complex dynamics associated with exceptional points in coupled spintronic nano-oscillators.
A system integrating CO2 conversion and energy storage holds great promise, but faces a major challenge due to degraded catalysts on charge. Here, the authors present a highly efficient energy storage and CO2 reduction method in an aqueous battery, achieved through oxidation of reducing molecules.
