Construction of a MOF‐Based Snap‐Top Delivery Nanosystem for Powerful Dual‐Responsive Synergistic Colitis Treatment

open access: yesAdvanced Science, EarlyView.
A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Analyzing the topology of N-linked glycans by PNGase F accessibility assay

open access: yesSTAR Protocols, 2023
Summary: While N-glycans are synthesized in the lumens, some of them reach the cytosolic side of membranes through retro-translocation independent of endoplasmic-reticulum-associated degradation.

Discovery of a Potent Fluorescence Polarization Probe for Identifying USP1 Allosteric Inhibitors

open access: yesAdvanced Science, EarlyView.
This study presents the first ubiquitin‐specific protease 1 (USP1) allosteric fluoroprobe and fluorescence polarization assay, enabling the differentiation of allosteric and catalytic site inhibitors. Further, a novel class of tetrahydroisoquinoline‐based USP1 inhibitors is designed, with compound 14a (USP1 IC50 = 29.9 nM) showing strong selectivity ...

Assessing in vitro stability of remdesivir (GS-5734) and conversion to GS-441524 in feline plasma and whole blood

open access: yesVeterinary Quarterly
Feline infectious peritonitis (FIP) is a potentially fatal coronavirus-driven disease of cats. Treatment with nucleoside analogue GS-441524 and or prodrug remdesivir (RDV) have produced remission in both experimentally induced and naturally occurring FIP,

Relative Exchangeable Copper Confirms Wilson Disease and Supports Reclassification of the ATP7B p.Met665Ile Variant With Conflicting Pathogenicity Evidence

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B mutations. Diagnosis is usually straightforward in symptomatic patients, but can be challenging in children and adolescents with mild liver disease, borderline urinary copper excretion, or inconclusive genetic findings.
