Selenoprotein H Functions as a PPARα Coactivator to Link Selenium Homeostasis to Hepatic Lipid Metabolism and Protect against Steatohepatitis

Advanced Science, EarlyView.
Our study identifies selenium deficiency as a hallmark of MASH pathogenesis. Dietary selenium supplementation enhances hepatic fatty acid oxidation (FAO) and attenuates MASH progression by activating the PPARα pathway via selenoprotein H (SELENOH). This selenium‐SELENOH‐PPARα nexus redefines the functional scope of selenoproteins, moving from redox ...

Caracterização da pureza de fosfatidilcolina da soja através de RMN de ¹H e de 31P Characterization of soybean phosphatidylcholine purity by ¹H and 31P NMR

Química Nova, 2008
A strategy is proposed to evaluate the purity of phosphatidylcholine from soybean lecithin, obtained by extraction or column chromatography, using the integrals ratio of ¹H NMR spectra.

Integrating Spatial Proteogenomics in Cancer Research

Advanced Science, EarlyView.
Xx xx. ABSTRACT Background: Spatial proteogenomics marks a paradigm shift in oncology by integrating molecular analysis with spatial information from both spatial proteomics and other data modalities (e.g., spatial transcriptomics), thereby unveiling tumor heterogeneity and dynamic changes in the microenvironment.

Selectivity Filter Dynamics Define Ion Conductance and Selectivity Differences in CNG and HCN Channels

Advanced Science, EarlyView.
Cyclic nucleotide‐gated (CNG) and hyperpolarization‐activated cyclic nucleotide‐gated (HCN) channels share substantial sequence and structural similarity but differ markedly in ion conductance and K+ selectivity. Microsecond‐scale atomistic MD simulations qualitatively reproduced the conductance differences observed in single‐channel recordings and ...

Quantification and Localisation of New Brain Lipid Synthesis Using Deuterium Oxide and High Resolution Mass Spectrometry

Angewandte Chemie, EarlyView.
Liquid chromatography tandem mass spectrometry and mass spectrometry imaging were used in combination with deuterium oxide administration to quantify and localise newly synthesised myelin lipids in the mouse brain. This methodology, used here to show sites of myelin repair, enables the measurement of dynamic lipid synthesis in living systems and ...

Phosphatidic Acid‐TRIM59‐Olig2 Signaling Couples Metabolic Dysfunction to Myelination Failure in PWMI

Advanced Science, EarlyView.
PA accumulates after hypoxic‐ischemic injury and stabilizes the E3 ligase TRIM59 in OPCs. Stabilized TRIM59 enhances ubiquitination and degradation of Olig2, blocking differentiation and causing hypomyelination in PWMI. Modulating PA synthesis restores Olig2 levels, improves myelination, and ameliorates behavioral deficits, defining a metabolically ...

GPX4 Inhibitor Resistance and Metastatic Features in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study establishes breast cancer cell lines that are resistant to glutathione peroxidase 4 inhibitors (GPX4i) in vitro and investigates the metastatic capacity of the GPX4i‐resistant versus parental lines in vivo. GPX4i‐resistant cells survive upon intravenous injection, but lose capacity to spontaneously metastasize.

Targeted Thrombolysis via CCR2‐Engineered Macrophage‐Mimicking Microbubbles Safely Ablates Venous, Arterial, and Microvascular Thrombosis

Advanced Science, EarlyView.
CCR2‐Enhanced Macrophage Membrane–Camouflaged Microbubbles for MCP‐1–Mediated Thrombus Targeting and Ultrasound‐Triggered Urokinase Release. ABSTRACT The clinical management of thrombosis, a primary cause of death worldwide, is hampered by the limitations of current thrombolytic agents, including short half‐life and high risk of off‐target bleeding ...

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

Advanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...
