This study reveals that mRNA recruitment to the ribosome follows a branched kinetic pathway where a reversible arrested state acts as a checkpoint, allowing factors like eIF4F and eIF3 to selectively bias mRNAs toward productive initiation based on their structural complexity.
This study presents an optimized workflow for haemoglobin depletion in dried blood spot microsamples that significantly enhances protein identification and biomarker discovery, particularly for monitoring chronic kidney disease, while also demonstrating the superior performance of commercial cell-free devices in capturing plasma-like profiles.
This study demonstrates that ionizing radiation induces dose- and model-dependent disruptions in cardiac mitochondrial bioenergetics and nucleotide homeostasis, revealing that while 10 Gy causes acute metabolic stress, 25 Gy triggers a paradoxical adaptive response that may underlie the immediate therapeutic effects of cardiac stereotactic body radiotherapy.
This study demonstrates that coating DNA origami nanoparticles with PEG5K-K10 significantly enhances their uptake and structural stability in Y-79 retinoblastoma cells without compromising vitreal mobility, whereas the addition of PL3 targeting peptides provided no further benefit.
The NanoBridge system is a modular platform that utilizes biologic binders to recruit small protein tags to challenging, often disordered endogenous proteins, enabling precise, reversible, and multiplexed post-translational modification editing in live cells without the need for exogenous PTM writers.
This study demonstrates that substituting heme B with structurally conservative non-natural metalloporphyrins in de novo designed tetrahelical proteins enables high-affinity binding and broad, predictable tuning of redox potentials by over 400 mV without compromising protein structure, establishing a versatile platform for engineered bioenergetic and bioelectronic applications.
This study reveals that the KN domain of KANK proteins consists of separable modules, where residues 30–60 mediate talin binding and residues 60–68 drive a conserved intramolecular interaction, establishing a modular architecture that supports an autoinhibitory regulatory mechanism.
This study establishes an optimized mass spectrometry workflow for the quantitative profiling of JMJD6-catalysed lysine hydroxylation, revealing that this modification exhibits residue-dependent oxygen sensitivity and heterogeneity in hypoxia-responsive kinetics across bromodomain proteins.
CascadeMAP is an autonomous, closed-loop microfluidic platform that integrates Bayesian optimization and multi-agent AI to rapidly optimize complex enzyme cascades without human intervention, processing hundreds of thousands of reactions to accelerate the development of biocatalytic systems.
Despite the potent in vitro inhibition of *Plutella xylostella* glycogen phosphorylase by specific inhibitors and RNAi knockdown, the enzyme is not a viable insecticidal target because the insect effectively compensates for the metabolic block through upregulated gluconeogenesis and protein catabolism, allowing for full developmental recovery and fitness.
