Synthesis of 11, 12-2H2- and 11, 12-3H2-labeled chenodeoxycholic and lithocholic acids
Journal of Lipid Research, 1976 Deuterium- and tritium-labeled chenodeoxycholic acid and lithocholic were prepared by catalytic reduction of their respective Δ11 derivatives. Structures of the intermediates and their isotopic purity were verified by chemical ionization and electron ...

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine
Advanced Science, EarlyView.This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...

A simplified method for synthesizing juvenile hormone-protein conjugates.
Journal of Lipid Research, 1990 A convenient and simple method is presented for the synthesis of juvenile hormone-thyroglobulin conjugates. Methods previously described for this hapten linkage have used a two-step process in which a reactive intermediate was isolated and then used for ...

A Genetically Encoded Biosensor for Characterizing Transport and Metabolism of Glutarate
Advanced Science, EarlyView.Here, a genetically encoded glutarate biosensor, Glusor, is developed based on transcriptional regulator CsiR. Glusor can quantify glutarate concentrations with good accuracy and precision. Then, the role of KgtP and YnfM are identified and characterized by using Glusor. Glusor also allows glutarate spatiotemporal resolution in live cells, facilitating
