NADH and NADPH are redox cofactors coexisting in all living cells. Here, the authors present a computational study suggesting that evolved NAD(P)H reaction specificities in E. coli are largely shaped by metabolic network structure enabling maximal thermodynamic driving forces close to the theoretical optimum.
Afatinib is a second-generation EGFR tyrosine kinase inhibitor recommended as the first-line treatment for patients with advanced EGFR mutant non-small cell lung cancer (NSCLC). Here the authors report the results of a phase II clinical trial of neoadjuvant afatinib for stage III EGFR mutant NSCLC.
Acclimation of tree photosynthesis to warming may be affected by elevated CO2. Here, the authors show that mature boreal conifers may be able to maintain leaf-level C uptake under warming and elevated CO2 even if optimum temperature of photosynthesis does not track increased temperature.
Achieving high pure formic acid production from CO2 electroconversion is of high interest yet challenging. Here the authors report vitamin C functionalized Bi3S2 nanowire catalyst to achieve selective, active, and stable formic acid production.
Mechanistic models estimate the phenotype of microorganisms in different environments but may have limited predictive capabilities. Here, authors develop trainable hybrid models with improved predictability using mechanistic insights and smaller training sets than conventional machine learning techniques.
Oxygen is essential for plant life. Here the authors define new functions and components of the plant oxygen sensing mechanism providing an understanding of the biochemistry of sensing and physiological responses allowing plant roots to survive in the soil.
The material-based evolution of organisms has attracted broad interdisciplinary interest, however, the fabrication of material-integrated organelles remains inadequately exploited. Here the authors engineer a bioartificial organism by integrating a semiartificial and specific virus-scavenging organelle to scavenge pathogenic waterborne viruses.
Untargeted metabolomics enables simultaneous measurement of xenobiotic fate and effects in biological systems. This is demonstrated through discovering extensive biotransformation maps, measuring systemic exposures over time, and directly associating endogenous biochemical responses to internal dose.
TP53 alteration and TMPRSS2-ERG fusion are often found together in prostate cancer. Here, the authors show that gain-of-function mutant p53 collaborates with ERG proto-oncogene to drive prostate cancer tumourigenesis by activating beta-catenin expression and afterwards pyrimidine synthesis.
The mechanism by which the chromatinized HBV genome is transcribed remains poorly understood. In this study, Liu et al. demonstrate how HBx exploits Spindlin1, a histone methylation reader, to overcome heterochromatin barriers and enhance HBV transcription from the cccDNA minichromosome.
Constructing the human reference atlas requires integration and analysis of massive amounts of data. Here the authors report the setup and results of the Hacking the Human Body machine learning algorithm development competition hosted by the Human Biomolecular Atlas and the Human Protein Atlas teams.
Single-cell DNA methylomic studies offer high resolution to differentiate cell subsets based on their epigenomic features. Here, the authors demonstrate Drop-BS, a droplet-based single-cell bisulfite sequencing library preparation method, for DNA methylome profiling.
Here the authors use fast kinetics, X-ray crystallography, and cryo-EM to uncover the mechanism of ribosome inhibition by amikacin and kanamycin. They find that amikacin binds near the P-site tRNA, offering new strategies to fight antibiotic resistance.
Molecules with axial chirality are of intense focus to the synthetic organic community, but the axes most commonly explored are carbon–carbon and carbon–heteroatom. Here the authors report the syntheses of diaxially chiral biaryls containing N-N and C-N/C-C axes, achieved via rhodium catalysis.
Cardiovascular and thromboembolic events (CVE) are common among hospitalised COVID-19 patients and are causes of many COVID-19-related deaths. Here, the authors examine whether genetic predisposition and lifestyle factors are associated with the risk of post-COVID-19 CVE using data from UK Biobank.
Replacement of oxoamide units with thioamides in peptide therapeutics is a valuable tactic to improve biological activity and resistance to enzymatic hydrolysis. Here, the authors develop a direct coupling of readily available nitroalkane and amines with elemental sulfur and base and provide an efficient way to form thioamides and thiopeptides.
Song et al. use the weaving principle to overcome load capacity limitations in soft grippers. The woven structure enables exceptional load capacity, supporting up to 100 kg·f with a 130 g·f gripper, while also offering adaptive interactions with objects.
Smooth topological photonic interfaces lead to less localized boundary modes which improves their guiding characteristics in both spin- and valley Hall metasurfaces. The modes become insensitive to the lattice details, showcasing improved bandgap crossing and longer propagation distances.
RNA variants derived from cancer-associated RNA editing events can be a source of neoantigens. Here, based on a proteogenomic pipeline combining DNA and RNA sequencing with MS-based immunopeptidomics, the authors identity and validate potential neoantigen candidates in patients with different tumor entities, highlighting RNA as important neoantigen source.
Robust photosynthetic light harvesting occurs in large membrane supercomplexes. Here, the authors show that supercomplexes occupy an unexpectedly large range of conformations yet maintain their efficiency due to specific, critical chlorophylls.
