Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

Mass Spectrometry Reviews, EarlyView.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

Mass Spectrometry Reviews, EarlyView.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

O-GlcNAc transferase inhibits visceral fat lipolysis and promotes diet-induced obesity

Nature Communications, 2020
Post-translational O-linked β-N acetylglucosamine (O-GlcNAc) modification acts as a nutrient-sensing mechanism. Here the authors report that O-GlcNAc transferase inhibits adipose tissue lipolysis via O-GlcNAcylation of the lipid droplet protein perilipin

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Molecular modelling and dynamic simulation of UDP-N-acetylglucosamine 1-carboxyvinyltransferase (MurA) from Mycobacterium tuberculosis using in silico approach

Informatics in Medicine Unlocked, 2018
UDP-N-acetylglucosamine 1-carboxyvinyltransferase (MurA) catalyses the biosynthesis of peptidoglycans in Mycobacterium tuberculosis (MTB) cell wall by adding enolpyruvyl to UDP-N-acetylglucosamine through an addition and elimination process.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Protocol for quantification of UDP-GlcNAc using an enzymatic microplate assay

STAR Protocols
Summary: Uridine diphosphate N-acetylglucosamine (UDP-GlcNAc) is the end product of the hexosamine biosynthetic pathway and the substrate for protein O-linked N-acetylglucosaminylation (O-GlcNAcylation). Here, we present a protocol for the quantification

Aging Is Associated With Impaired Activation of Protein Homeostasis‐Related Pathways After Cardiac Arrest in Mice

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background The mechanisms underlying worse outcome at advanced age after cardiac arrest (CA) and resuscitation are not well understood. Because protein homeostasis (proteostasis) is essential for cellular and organismal health, but is impaired after CA ...

Hcfc1 and Ogt Mediate Zebrafish CNS Regeneration Through Hippo/Yap Signalling

Cell Proliferation, EarlyView.
This work identifies Hcfc1 and Ogt as key regulators of zebrafish CNS regeneration through modulation of Hippo/Yap signalling. Loss of Hcfc1 or Ogt activity inhibition impairs regeneration, which is restored by Yap overexpression, revealing a new regulatory axis that enhances CNS regenerative capacity.
