The understanding of molecular mechanisms in different subtypes of head and neck cancer (HNC) will define subtype-specific treatment options. Here the authors show that PI3K-phospho-YBX1 axis promotes tumour growth in basal subtype of HNC, while unphosphorylated YBX1 acts as a suppressor of metastasis in the mesenchymal subtype with inactive PI3K signalling.
Immunotherapies have shown limited efficacy in patients with glioma. Here, based on an in vivo kinome knockout CRISPR screen, the authors show that checkpoint kinase 2 promotes CD8 T cell immune evasion and that its depletion or inhibition improve survival and response to PD1/PDL1 blockade in preclinical glioma models.
Correlation between vaccine induced serological response and protection against SARS-CoV-2 omicron infection is not well understood. Authors investigate breakthrough infections in triple-vaccinated healthcare workers, to characterise correlates of protection and viral characteristics.
Plants respond to light and temperature changes via the photoreceptor phytochrome B and the phytohormone auxin. Here the authors reveal microRNA156 as a previously uncharacterized developmental signal that gates environmentally regulated plant growth by licensing auxin sensitivity.
Comprehensive understanding of the human protein-protein interaction network, aka the human interactome, can provide important insights into the molecular mechanisms of complex biological processes and diseases. Here the authors summarize the community efforts initiated by the International Network Medicine Consortium to benchmark the ability of 26 representative network-based methods to predict protein-protein interactions.
One of the ambitions of computational neuroscience is that we will continue to make improvements in the field of artificial intelligence that will be informed by advances in our understanding of how the brains of various species evolved to process information. To that end, here the authors propose an expanded version of the Turing test that involves embodied sensorimotor interactions with the world as a new framework for accelerating progress in artificial intelligence.
Here, the authors track the evolution of mass distribution through bird evolution challenging suggested coupling between body shape and centre-of-mass position, and instead showing that crouched bipedalism evolved after powered flight.
It is challenging to approach protein structures in living cells. Here the authors investigate Interleukin-4 receptor alpha, which has a noncanonical amino acid incorporated at different locations, and see that evaluating click efficiency with calibrated imaging gives information on structure-related properties.
The heart requires high levels of mitochondria to sustain function, and mitochondrial stressors can be transmitted to the nucleus and reprogram metabolism. Here, the authors show that a mitochondrial ribosomal protein is important for heart development in mice by increasing nuclear Klf15 expression.
The two-component regulatory system VraRS regulates transcription of penicillin-binding protein 2 in response to cell wall antimicrobials. Here, Lu et al. show that an enzyme from the wall teichoic acid biosynthetic pathway of MRSA can also modulate the expression of virulence factors such as Staphylococcal protein A via VraRS.
Nackednaviruses and hepatitis B virus (HBV) have a common non-enveloped viral ancestor. While HBV acquired an envelope during evolution, nackednaviruses remained non-enveloped. Here, Pfister et al. apply CryoEM and NMR to characterize the capsid structure of African cichlid nackednavirus (ACNDV) at pH 5.5 and pH 7.5 and show that the capsid structure is very similar to that of HBV.
Glioblastoma stem-like cells (GSCs) contribute to therapeutic resistance and recurrence of glioblastomas. Here the authors show that Insulin-like Growth Factor-Binding Protein 5 (IGFBP5) is a ligand for Receptor tyrosine kinase-like Orphan Receptor 1 (ROR1) promotes GSCs invasion.
Androgen effects have been poorly studied in demyelinating diseases in females. Here, authors show androgen requirement for proper myelin regeneration in females and the critical need to consider male-female differences in multiple sclerosis patients.
The median eminence (ME) at the base of the brain controls body homeostasis. Here, the authors describe a functional tanycyte subpopulation at the ME which tastes the surrounding milieu, responds to metabolic signals and regulates glucose homeostasis.
Analysing the regulatory consequences of mutations and splice variants at large scale in cancer requires efficient computational tools. Here, the authors develop RegTools, a software package that can identify splice-associated variants from large-scale genomics and transcriptomics data with efficiency and flexibility.
Altered Ca2+ signaling is involved in the pathogenesis of Alzheimer’s disease. Here, the authors show Ca2+ hypoactivity in astrocytes at plaque deposition onset related to reduced expression of the Ca2+ sensor STIM1 and impaired synaptic plasticity that was rescued by STIM1 overexpression in astrocytes.
Rivers are among the most diverse, dynamic, and productive ecosystems on Earth. Here, using Landsat imagery, the authors provide a global attribution of the recent changes in river regime to morphological dynamics, dam-induced widening, and hydrological signals.
The device efficiency of organic solar cells is usually limited by the inherent energy loss during carrier transport. Here, authors integrate bulk heterojunction organic photovoltaic with vertical field effect transistor, leading to reduced energy loss below 0.2 eV as controlled by the gate voltage.
STING agonists have shown limited efficacy in early-phase clinical trials despite promising pre-clinical data. This study shows the potential clinical relevance of the use of combination STING agonists and demethylating agent therapies to induce the expression of STING.
There is a lack of standardisation in slide microscopy imaging data. Here the authors report Slim, an open-source, web-based slide microscopy viewer implementing the Digital Imaging and Communications in Medicine (DICOM) standard to achieve interoperability with a range of existing medical imaging systems.
