Deficient O-GlcNAc Glycosylation Impairs Regulatory T Cell Differentiation and Notch Signaling in Autoimmune Hepatitis

open access: yesFrontiers in Immunology, 2018
Post-translational modifications such as glycosylation play an important role in the functions of homeostatic proteins, and are critical driving factors of several diseases; however, the role of glycosylation in autoimmune hepatitis is poorly understood.

Abnormal sialylation and fucosylation of saliva glycoproteins: Characteristics of lung cancer-specific biomarkers

open access: yesCurrent Research in Pharmacology and Drug Discovery, 2022
Dysregulated surface glycoproteins play an important role in tumor cell proliferation and progression. Abnormal glycosylation of these glycoproteins may activate tumor signal transduction and lead to tumor development.

N-GlycoGo: Predicting Protein N-Glycosylation Sites on Imbalanced Data Sets by Using Heterogeneous and Comprehensive Strategy

open access: yesIEEE Access, 2020
Glycosylation is the most complex post-modification effect of proteins. It participates in many biological processes in the human body and is closely related to many disease states.

Folding of Pig Gastric Mucin Non-glycosylated Domains: A Discrete Molecular Dynamics Study [PDF]

open access: yesarXiv, 2009
Mucin glycoprotein consist of tandem repeating glycosylated regions flanked by non-repetitive protein domains with little glycosylation. These non-repetitive domains are involved in the pH dependent gelation of gastric mucin, which is essential to protecting the stomach from autodigestion.

Mass Spectrometry in the Elucidation of the Glycoproteome of Bacterial Pathogens [PDF]

open access: yes, 2010
Presently some three hundred post-translational modifications are known to occur in bacteria in vivo. Many of these modifications play critical roles in the regulation of proteins and control key biological processes.

Extracellular Domain N-Glycosylation Controls Human Thrombopoietin Receptor Cell Surface Levels

open access: yesFrontiers in Endocrinology, 2011
The thrombopoietin receptor (TpoR) is a type I transmembrane protein that mediates the signaling functions of thrombopoietin (Tpo) in regulating megakaryocyte differentiation, platelet formation and hematopoietic stem cell renewal.

Variation of the serum N‐glycosylation during the pregnancy of a MPI‐CDG patient

open access: yesJIMD Reports, 2021
For the first time the glycosylation of a patient with a MPI‐CDG during pregnancy is monitored. MPI‐CDG, is characterised by a deficiency in mannose‐6‐phosphate isomerase (MPI) leading to a reduced pool of glycosylation precursors, impairing the ...

Glucose values prediction five years ahead with a new framework of missing responses in reproducing kernel Hilbert spaces, and the use of continuous glucose monitoring technology [PDF]

open access: yesarXiv, 2020
AEGIS study possesses unique information on longitudinal changes in circulating glucose through continuous glucose monitoring technology (CGM). However, as usual in longitudinal medical studies, there is a significant amount of missing data in the outcome variables.

Accelerating Bayesian inference of dependency between complex biological traits [PDF]

open access: yesarXiv, 2022
Inferring dependencies between complex biological traits while accounting for evolutionary relationships between specimens is of great scientific interest yet remains infeasible when trait and specimen counts grow large. The state-of-the-art approach uses a phylogenetic multivariate probit model to accommodate binary and continuous traits via a latent ...

A Poglut1 mutation causes a muscular dystrophy with reduced Notch signaling and satellite cell loss [PDF]

open access: yes, 2016
Skeletal muscle regeneration by muscle satellite cells is a physiological mechanism activated upon muscle damage and regulated by Notch signaling. In a family with autosomal recessive limbgirdle muscular dystrophy, we identified a missense mutation in ...
