CysNet is a novel theorem-constrained computational method that overcomes the limitations of traditional bottom-up mass spectrometry by inferring specific cysteine redox proteoform states (oxiforms) from residue-level data, thereby enabling the deepest and most detailed survey of redox variation to date.
The paper introduces SANDLE, a dual-strategy statistical tool that overcomes the limitations of existing marker-dependent and marker-free methods to provide faster, more robust, and versatile analysis of differential subcellular localization across complex experimental designs.
This study reports the synthesis, purification, and structural characterization of rhodoquinone-9 and -10 analytical standards, enabling their absolute quantification and confident identification in mammalian tissues via LC-MS/MS.
This paper introduces a method to infer ion mobility collision cross section (CCS) values directly from standard LC-Orbitrap mass spectrometry data by correcting for solvent-dependent pressure variations using internal standards, thereby enabling high-precision structural annotation of lipid isomers without requiring specialized ion mobility hardware.
This study demonstrates that oxidative stress induces human endothelial progenitor cell dysfunction by upregulating miR-34a-3p, which directly targets and suppresses the FoxO3a 3'UTR, creating a post-transcriptional feedback loop that exacerbates cell apoptosis and impairs angiogenic capacity.
This study utilizes a comprehensive, statistically rigorous analysis of all 64 mutation combinations in a phosphotriesterase across nine diverse substrates to reveal how substrate-dependent intramolecular network rewiring drives functional trade-offs and defines the molecular basis of enzyme promiscuity and adaptive evolution.
This study elucidates the structural and biochemical mechanisms by which the clinical antivirals nirmatrelvir and ensitrelvir inhibit the main protease of the emerging human-adapted HKU5-CoV-2, revealing conserved inhibitor recognition modes that support the development of broad-spectrum antivirals against merbecoviruses.
This paper demonstrates that synthetic cell-penetrating thyclotides (CPTs) effectively overcome membrane barriers to enable the efficient cellular uptake and endosomal escape of bioactive peptides, thereby offering a promising new strategy for developing intracellular therapies.
The paper introduces microProteomEx, an integrated platform combining tissue expansion, laser capture microdissection, and mass spectrometry to achieve simultaneous three-dimensional super-resolution imaging and deep spatial proteomics in both mechanically resilient tissues and formalin-fixed clinical samples, enabling the correlation of nanoscale ultrastructure with molecular heterogeneity for disease biology and precision medicine.
This study demonstrates that zinc ions differentially modulate tau aggregation, fibril morphology, and prion-like seeding in a construct-dependent manner, revealing that cofactor effects arise from their specific interplay with tau sequence and conformational constraints rather than being intrinsic properties of the cofactor itself.
