The endosomal system is a highly dynamic multifunctional organelle, whose complexity is regulated in part by reversible ubiquitylation. Despite the wide-ranging influence of ubiquitin in endosomal processes, relatively few enzymes utilizing ubiquitin have been described to control endosome integrity and

Journal of colloid and interface science, 527, 315-327 (2018-05-29)
Research to improve the dimensional properties of silver nanowires (Ag NWs) for transparent conductive film (TCF) applications are being carried out intensively. However, the protocol for the designed synthesis of high-quality Ag NWs is yet to be developed due to
Søren Bertelsen et al.

A new concept in organocatalysis is presented, the direct asymmetric gamma-functionalization of alpha,beta-unsaturated aldehydes. We disclose that secondary amines can invert the usual reactivity of alpha,beta-unsaturated aldehydes, enabling a direct gamma-amination of the carbonyl compound using azodicarboxylates as the electrophilic

Analytical biochemistry, 578, 13-22 (2019-05-07)
γ-Glutamylpeptides are largely produced via the action of γ-glutamylcysteine synthetase or γ-glutamyltransferase (GGT). GGT transfers the γ-glutamyl moiety from glutathione (GSH) and other γ-glutamyl compounds to amino acids, peptides, or water. A conventional GGT assay employs a synthetic donor substrate
Visible-light-induced oxidation/[3+ 2] cycloaddition/oxidative aromatization sequence: a photocatalytic strategy to construct pyrrolo [2, 1-a] isoquinolines.
Zou YQ, et al.
Angewandte Chemie (International Edition in English), 50(31), 7171-7175 (2011)
Salima Daou et al.
Nature communications, 9(1), 4385-4385 (2018-10-24)
The tumor suppressor and deubiquitinase (DUB) BAP1 and its Drosophila ortholog Calypso assemble DUB complexes with the transcription regulators Additional sex combs-like (ASXL1, ASXL2, ASXL3) and Asx respectively. ASXLs and Asx use their DEUBiquitinase ADaptor (DEUBAD) domain to stimulate BAP1/Calypso
Hui Zhou et al.
The Analyst, 143(10), 2390-2396 (2018-04-27)
Glutathione (GSH) exhibits many cellular functions in human pathologies. A sensitive and simple method capable of assaying GSH would be useful to understand the mechanism of GSH-related diseases. In this study, a new colorimetric and fluorescent off-on probe, 3-oxo-3H-phenoxazin-7-ylthiophene-2-carboxylate, is
Takujiro Homma et al.
Free radical research, 54(6), 397-407 (2020-07-02)
Ferroptosis is a type of iron-dependent, non-apoptotic cell death, which is typically induced by the suppression of phospholipid hydroperoxide-glutathione peroxidase (GPX4) activity and a corresponding elevation in lipid peroxidation products. While the inhibition of the xCT-mediated uptake of cystine commonly
Sandip Mukherjee et al.
Nature immunology, 21(6), 626-635 (2020-05-20)
The inflammasome NLRP6 plays a crucial role in regulating inflammation and host defense against microorganisms in the intestine. However, the molecular mechanisms by which NLRP6 function is inhibited to prevent excessive inflammation remain unclear. Here, we demonstrate that the deubiquitinase
Young-Chan Kim et al.
Nature chemical biology, 15(9), 907-916 (2019-08-21)
Toll-like receptor (TLR)/myeloid differentiation primary response protein (MYD88) signaling aggravates sepsis by impairing neutrophil migration to infection sites. However, the role of intracellular fatty acids in TLR/MYD88 signaling is unclear. Here, inhibition of fatty acid synthase by C75 improved neutrophil
A facile procedure for controlling monomer sequence distribution in radical chain polymerizations.
Pfeifer S and Lutz JF
Journal of the American Chemical Society, 129(31), 9542-9543 (2007)
Gyul Moon et al.
Free radical research, 54(8-9), 606-619 (2020-09-09)
Acetaminophen (APAP) overdose is a major cause of drug-induced acute liver failure. In such cases, free iron is released from lysosomes and is transported to mitochondria where it plays a pivotal role in APAP-induced liver injury. We previously reported that
Sho Kobayashi et al.
Biochemical and biophysical research communications, 491(3), 649-655 (2017-08-02)
Glutathione (GSH) plays pivotal roles in antioxidation and detoxification. The transsulfuration pathway, in conjunction with methionine metabolism, produces equimolar amounts of cysteine (Cys) and 2-oxobutyric acid (2OB). The resulting 2OB is then converted into 2-aminobutyric acid (2AB) by a transaminase
Takujiro Homma et al.
Experimental cell research, 384(1), 111592-111592 (2019-09-04)
Ferroptosis is characterized by an iron-dependent cell death with increased lipid peroxidation and is typically induced by either a decrease in glutathione (GSH) levels due to an insufficient supply of cysteine (Cys) or the inhibition of phospholipid hydroperoxide glutathione peroxidase
Eun Jo Du et al.
PLoS genetics, 12(1), e1005773-e1005773 (2016-01-05)
Pathogen expulsion from the gut is an important defense strategy against infection, but little is known about how interaction between the intestinal microbiome and host immunity modulates defecation. In Drosophila melanogaster, dual oxidase (Duox) kills pathogenic microbes by generating the

Hydrogels with photo-responsive mechanical properties have found broad biomedical applications, including delivering bioactive molecules, cell culture, biosensing, and tissue engineering. Here, using a photocleavable protein, PhoCl, as the crosslinker we engineer two types of poly(ethylene glycol) hydrogels whose mechanical stability

The regulatory role of protein cysteine phosphorylation is an under-researched area. The difficulty of accessing reference S-phosphorylated peptides (pCys-peptides) hampers progress in MS-driven cysteine phosphoproteomics, which requires targeted analytical procedures. This work describes an uncomplicated process for the conversion of
