Identification of a carbohydrate recognition motif of purinergic receptors

eLife, 2023
As a major class of biomolecules, carbohydrates play indispensable roles in various biological processes. However, it remains largely unknown how carbohydrates directly modulate important drug targets, such as G-protein coupled receptors (GPCRs).

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Identification and characterization of the functional tetrameric UDP-glucose pyrophosphorylase from Klebsiella pneumoniae

mBio
In all kingdoms of life, the enzyme uridine diphosphate-glucose pyrophosphorylase (UGP) occupies a central role in metabolism, as its reaction product uridine diphosphate-glucose (UDP-Glc) is involved in various crucial cellular processes.

O‐GlcNAcylation Regulation of SNAP29‐Dependent Autophagy Activation Dictates Chemoresistance in Gastric Cancer

Advanced Science, EarlyView.
Model illustrating the proposed mechanism by which chemotherapy‐induced downregulation of OGT disrupts SNAP29 O‐GlcNAcylation, promoting STX17‐SNAP29‐VAMP8 SNARE complex assembly and protective autophagy, leading to chemoresistance, which in turn establishes a feedforward loop to perpetuate drug tolerance.

Glutamine deprivation triggers NAGK-dependent hexosamine salvage

eLife, 2021
Tumors frequently exhibit aberrant glycosylation, which can impact cancer progression and therapeutic responses. The hexosamine biosynthesis pathway (HBP) produces uridine diphosphate N-acetylglucosamine (UDP-GlcNAc), a major substrate for glycosylation ...

Pharmacogenomics of dolutegravir: A scoping review of evidence, gaps and clinical implications

British Journal of Clinical Pharmacology, EarlyView.
Dolutegravir underpins modern first‐ and second‐line HIV treatment regimens; however, interindividual variability in its disposition and tolerability presents challenges for optimal use. This scoping review mapped current evidence on the pharmacogenomics of dolutegravir, focusing on pharmacokinetics and pharmacodynamics, and methodological limitations ...

Selective Detoxification of Phenols by Pichia pastoris and Arabidopsis thaliana Heterologously Expressing the PtUGT72B1 from Populus trichocarpa. [PDF]

PLoS ONE, 2013
Phenols are present in the environment and commonly in contact with humans and animals because of their wide applications in many industries. In a previous study, we reported that uridine diphosphate-glucose-dependent glucosyltransferase PtUGT72B1 from ...

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Review of Congenital Myasthenic Syndrome Caused by Pathogenic Variants in GFPT1

Muscle &Nerve, EarlyView.
ABSTRACT Glutamine:fructose‐6‐phosphate transaminase 1 (GFPT1) catalyzes the first and rate‐limiting step of the hexosamine biosynthetic pathway (HBP) to generate UDP‐GlcNAc. GFPT1 exon 9 is specifically spliced in in striated muscles, which makes a long isoform of GFPT1 (GFPT1‐L).
