Multi‐Omics Profiling of High‐Grade Serous Ovarian Cancer Reveals an Inflammation‐Related Lipid Metabolism Subtype Associated With Platinum Resistance

open access: yesAdvanced Science, EarlyView.
Through integrated proteomic and metabolomic profiling, Zhao et al. identified three molecular subtypes of high‐grade serous ovarian cancer. The high‐risk subtype exhibits activated arachidonic acid metabolism and cyclooxygenase‐2 overexpression. This metabolic axis promotes M2‐like macrophage infiltration, which contributes to platinum resistance ...

Level of Arachidonic Acid and State of Peroxidation Processes in Patients with Aspirin-Intolerant Polypous Rhinosinusitis

open access: yesGalician Medical Journal, 2016
The main peculiarity of aspirin-intolerant polypous rhinosinusitis pathogenesis is the presence of “genetic block” of constitutive cyclooxygenase being the key enzyme of the arachidonic acid metabolism.

Super‐Multiplexed Label‐Free Raman Imaging Uncovers Novel Testicular Metabolic Couplings for Residual Body and Spermatogonial Differentiation

open access: yesAdvanced Science, EarlyView.
Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease.

Magneto‐NIR‐II‐Programmed Cascade Nanozymes Unlocking Blood–Brain Barrier Translocation and Autophagic Resistance in Glioblastoma

open access: yesAdvanced Science, EarlyView.
Magneto‐NIR‐II‐programmed NFSH nanozymes integrate magnetic blood–brain barrier (BBB) translocation, CD44 targeting, multimodal imaging, and cascade catalytic therapy for glioblastoma. Alternating magnetic fields and NIR‐II irradiation amplify ferroptosis, release H2S, suppress autophagic and mitophagic repair, and reshape the immune microenvironment ...

Albumin modifies the metabolism of hydroxyeicosatetraenoic acids via 12-lipoxygenase in human platelets

open access: yesJournal of Lipid Research, 1999
12-Lipoxygenase and cyclooxygenase 1 are the dominating enzymes that metabolize arachidonic acid in human platelets. In addition to the conversion of arachidonic acid to 12(S)-hydroxyeicosatetraenoic acid, 12-lipoxygenase can also utilize 5(S ...

Composition‐Aware Cross‐Sectional Integration for Spatial Transcriptomics

open access: yesAdvanced Intelligent Discovery, EarlyView.
Multi‐section spatial transcriptomics demands coherent cell‐type deconvolution, domain detection, and batch correction, yet existing pipelines treat these tasks separately. FUSION unifies them within a composition‐aware latent framework, modeling reads as cell‐type–specific topics and clustering in embedding space.

Conversion of eicosapentaenoic acid to chain-shortened omega–3 fatty acid metabolites by peroxisomal oxidation1

open access: yesJournal of Lipid Research, 1998
Human skin fibroblasts can convert arachidonic acid to 14- and 16-carbon polyunsaturated fatty acid products by peroxisomal β-oxidation. The purpose of this study was to determine whether similar products are formed from eicosapentaenoic acid (EPA) and ...

Tamoxifen stimulates arachidonic acid release from rat liver cells by an estrogen receptor-independent, non-genomic mechanism

open access: yesBMC Cancer, 2003
Background Tamoxifen is widely prescribed for the treatment of breast cancer. Its success has been attributed to the modulation of the estrogen receptor.

Inhibition of the Nicotinic Ion Channel by Arachidonic Acid and Other Unsaturated Fatty, Acids in Chromaffin Cells from Bovine Adrenal Medulla

open access: yesCHIMIA, 1991
The effects of arachidonic and other cis-unsaturated fatty acids were investigated in cultured chromaffin cells from bovine adrenal medulla with respect to Ca2+ influx and secretion of catecholamines.

Arachidonic Acid Stress Impacts Pneumococcal Fatty Acid Homeostasis

open access: yesFrontiers in Microbiology, 2018
Free fatty acids hold dual roles during infection, serving to modulate the host immune response while also functioning directly as antimicrobials. Of particular importance are the long chain polyunsaturated fatty acids, which are not commonly found in ...
