A genome-wide association study reveals specific transferases as candidate loci for bovine milk oligosaccharides synthesis. [PDF]

open access: yes, 2019
BackgroundHuman milk oligosaccharides (OS) play a key role in brain and gut microbiota development of the neonate, but the underlying biosynthetic steps of OS in the mammary gland are still largely unknown.

Segmentally Variable Genes: A New Perspective on Adaptation [PDF]

open access: yes, 2004
Genomic sequence variation is the hallmark of life and is key to understanding diversity and adaptation among the numerous microorganisms on earth. Analysis of the sequenced microbial genomes suggests that genes are evolving at many different rates.

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication

open access: yesChemistry – A European Journal, EarlyView.
This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.

High degree of conservation of the enzymes synthesizing the laminin-binding glycoepitope of α-dystroglycan

open access: yesOpen Biology, 2021
The dystroglycan (DG) complex plays a pivotal role for the stabilization of muscles in Metazoa. It is formed by two subunits, extracellular α-DG and transmembrane β-DG, originating from a unique precursor via a complex post-translational maturation ...

Targeting MGAT4A‐Mediated N‐Glycosylation as a Therapeutic Strategy to Inhibit Glioblastoma Stem Cell Invasion

open access: yesExploration, EarlyView.
ABSTRACT Glioblastoma (GBM) is the most aggressive type of primary brain tumor, and its invasive properties contribute significantly to incomplete surgical resection and tumor recurrence. Despite extensive clinical efforts to mitigate GBM invasion, targeted therapies against GBM stem cells (GSCs), which drive invasion, remain incompletely understood ...

Lipooligosaccharides (LOS) of Neisseria gonorrhoeae and Neisseria meningitidis have components that are immunochemically similar to precursors of human blood group antigens. Carbohydrate sequence specificity of the mouse monoclonal antibodies that recognize crossreacting antigens on LOS and human erythrocytes. [PDF]

open access: yes, 1988
We have used mouse mAbs, 3F11 and 06B4, that are specific for highly conserved epitopes of Neisseria gonorrhoeae lipooligosaccharides (LOS) to identify immunochemically similar structures on human erythrocytes. mAb 3F11 agglutinated erythrocytes from all

Processivity in Bacterial Glycosyltransferases [PDF]

open access: yesACS Chemical Biology, 2019
Extracellular polysaccharides and glycoproteins of pathogenic bacteria assist in adherence, autoaggregation, biofilm formation, and host immune system evasion. As a result, considerable research in the field of glycobiology is dedicated to study the composition and function of glycans associated with virulence, as well as the enzymes involved in their ...
