Here the authors combine next generation sequencing on plasma from participants of the ADVANCE clinical trial with virological and follow-up data to investigate the impact of pre-treatment drug resistance (PDR) to non-nucleoside reverse transcriptase inhibitors (NNRTIs) on the efficacy of second-generation integrase inhibitors and find an association between NNRTI resistance prior to treatment and long-term treatment.
Altered protein glycosylation is increasingly recognized as a hallmark of cancer. Here, the authors profile the glycoproteome of 119 high-grade serous ovarian carcinoma tissues, showing that glycosylation patterns correlate with tumor molecular subtypes and clinical outcomes.
In the habitable zone concept, a planet’s carbon dioxide-water greenhouse maintains surface liquid water. Here, the authors estimate how many Earthlike exoplanets are needed to detect a relationship between stellar flux and the atmospheric carbon dioxide predicted by carbon cycle modeling.
Forests are critical for stabilizing our climate, but costs of mitigation remain uncertain. Here the authors show the global forest sector could reduce emissions by 6.0 GtCO2 yr−1 in 2055, or roughly 10% of the mitigation needed to limit warming to 1.5 °C by mid-century, at a cost of 393 billion USD yr−1, or $281/tCO2.
Reliable plasmonic biosensors with high throughput and ease of use are highly sought after. Here, the authors report a plasmon-enhanced fluorescence antibody-aptamer biosensor based on a gold nanoparticle array, and demonstrate its use for effective specific detection of a malaria marker, at femtomolar level, in whole blood.
Combinatorial treatments have become a standard of care for various complex diseases including cancers. Here, the authors show that combinatorial responses of two anticancer drugs can be accurately predicted using factorization machines trained on large-scale pharmacogenomic data for guiding precision oncology studies.
Immune cells express immunoproteasomes (i20S), which bind to specialized regulators, contain different catalytic subunits and generate immunogenic peptides. HDX-MS—based assessment of the differences between the conformational dynamics of standard and i20s reveals specific, allosteric changes in i20S and upon regulator binding.
Controlling and modulating charge transfer dynamics in composite nanostructures, though promising for optoelectronic applications, remains a challenge. Here, the authors report optical control of charge separation and recombination processes in organic semiconductor-based composite nanostructures.
Bacterial vaginosis (BV) is typically caused by a shift in the vaginal microbiota from a Lactobacillus-dominant community to one colonised by strains of Gardenerella vaginalis and treatment with the antibiotic metronidazole (MNZ) often results in failure and recurrence. Here, the authors use modelling and in vitro assays to show that sequestration of MNZ by Lactobacillus is critical in reducing efficacy and women with a higher pre-treatment Lactobacillus/Gardnerella ratio are more likely to recur.
Accurate cell detection in dense bacterial biofilms is challenging. Here, the authors report an image analysis pipeline that is able to accurately segment and classify single bacterial cells in 3D fluorescence images: Bacterial Cell Morphometry 3D (BCM3D).
Type I interferon drives autoimmune pathology in SLE and has been assumed to come predominantly from plasmacytoid dendritic cells (pDCs). Here, the authors show that prior to the onset of SLE, pDCs lose multiple immunogenic functions and, instead, non-hematopoietic cells such as keratinocytes are a major source of type I interferons.
Cell proliferation is regulated by cell volume, but it is unclear how individual cancer cells coordinate to regulate cell volumes in 3D clusters. Here the authors propose a mechano-osmotic model to analyse the exchange of fluid and ions between connected cells and their environment in response to proliferation-induced solid stress.
Polymer thin films that emit and absorb circularly polarised light are promising in achieving important technological advances, but the origin of the large chiroptical effects in such films has remained elusive. Here the authors demonstrate that in non-aligned polymer thin films, large chiroptical effects are caused by magneto-electric coupling, not structural chirality as previously assumed.
Maintenance of a mitochondrial NAD+ pool is critical for cellular life, yet the existence and identity of the transporter responsible for mitochondrial NAD+ uptake was unknown until recently. Here, the authors use genomic, genetic, and metabolomic approaches to demonstrate that SLC25A51 controls NAD+ mitochondrial levels and is the functional homolog of the yeast mitochondrial NAD+ transporter.
Long non coding RNA molecules have been implicated in the immunopathology of a range of inflammatory pathologies. Here the authors show lncRNA MAARS regulates apoptosis via interaction with HuR in the context of atherosclerosis.
The role of cohesin in organizing a functional nuclear architecture remains poorly understood. Here the authors show that cohesin depleted cells pass through endomitosis forming a multilobulated nucleus able to proceed through S-phase with typical features of active and inactive nuclear compartments and spatio-temporal patterns of replication domains.
Spin damping plays a fundamental role in many areas of spintronics, however, it is typically assumed that damping is irrelevant for impulsive spin excitations due to their rapid timescale. Here, the authors demonstrate that damping leads to a large and immediate spin-canting in anti-ferromagnets.
Bedaquiline (BDQ) is a known tuberculosis treatment, but the precise mechanism of cell death is unclear. Here, the authors explore the metabolic profiles of M. tuberculosis upon BDQ treatment and find reliance on glycolysis and synergistic cell death when oxidative phosphorylation is also targeted.
