This study demonstrates that 2,3-DPG levels in stored red blood cells exhibit significant inter-unit variability and rapid depletion well before the 42-day expiration, suggesting that using storage duration as a proxy for metabolic state misclassifies the actual oxygen-unloading capacity of transfused units.
This study introduces a tandem Rh1::eGFP-mCherry fluorescent reporter to reveal that immature Rhodopsin 1 accumulates in previously unrecognized acidified subdomains within the endoplasmic reticulum of Drosophila photoreceptors during vitamin A deficiency, thereby establishing a new stage in rhodopsin quality control.
This cross-sectional study of asymptomatic adults reveals that serine depletion, driven by increased demands for sphingolipid and transsulfuration metabolism, is mechanistically linked to elevated cytotoxic deoxyceramides and reduced one-carbon metabolites, which are strongly associated with fasting triglycerides and insulin resistance as key cardiovascular risk factors.
This study identifies and characterizes a novel glycosaminoglycan-degrading Polysaccharide Utilization Locus in the oral bacterium *Segatella oris*, including the biochemical and structural analysis of the first reported *Prevotellaceae* endosulfatase.
This study employs activity-based probes and proteomics to systematically profile the activity and abundance of deubiquitinases in dendritic cells under both unstimulated and CpG-stimulated conditions, revealing dynamic changes that identify key enzymes for further investigation.
By combining lysosomal proteomics with targeted knockdowns, this study systematically defines the distinct cargo spectra of the GARP and EARP tethering complexes, revealing that GARP depletion impairs lysosomal hydrolase delivery while EARP depletion causes the accumulation of secreted proteins, thereby providing a crucial framework for understanding the pathological consequences of their dysfunction in neurodegenerative disorders.
This study reveals that the histone chaperone FACT facilitates cohesin translocation along nucleosome-dense chromatin to promote efficient loop extrusion and maintain topologically associating domain boundaries, while preventing cohesin's aberrant accumulation in gene bodies that would otherwise suppress transcription.
Contrary to the expectation that extending peptide chains narrows the HOMO-LUMO gap through conjugation, this study reveals that the gap reduction is actually driven by the polar backbone's electrostatic ramp, which aligns localized frontier orbitals at opposite chain ends without delocalizing electron density across the aromatic residues.
This study demonstrates that the pro-inflammatory protein S100A9 promotes the aggregation of prion proteins by forming heterotypic liquid-liquid phase separation condensates, which subsequently accelerate the formation of amyloid structures under high molecular crowding conditions.
This study introduces MemGraft-NR, a robust covalent solvatochromic membrane probe that uniquely enables the sensing of lipid organization and polarity specifically at the protein-lipid interface, revealing distinct environmental characteristics and dynamic responses to cholesterol and membrane curvature that are inaccessible to traditional lipid-bound probes.
