Fluorinated rhamnosides inhibit cellular fucosylation

Nature Communications, 2021
Aberrant expression of fucosylated glycans has been linked to several disease states. Control of fucose expression on live cells is needed to aid research and therapy development.

Modulation of Animal Gut Health by Milk Oligosaccharide

Animal Research and One Health, EarlyView.
This review summarizes the composition and structural characteristics of MOs across different mammalian species, and elucidates their roles and mechanisms in maintaining intestinal homeostasis by regulating gut microbiome and enhancing intestinal chemical, physical and immune barriers.

IgG Glycosylation‐Dependent CLEC7A Signaling Drives Podocyte Dysfunction in Lupus Nephritis

Arthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) that can lead to end‐stage kidney disease and increased mortality. IgG from patients with LN displays abnormal glycosylation, contributing to podocyte injury.

Unmasking Glycoforms: Lectin‐Based Profiling and Functional Implications of Targeted Glycosylation Knockouts in Chinese Hamster Ovary Cells

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Monoclonal antibody (mAb) glycosylation is a critical quality attribute that is difficult to rationally engineer and rapidly assess during cell line development. Here, we investigate whether cell‐surface glycosylation can serve as a surrogate readout of mAb product glycosylation following targeted glycogene engineering in CHO cells.

Abnormal B cell glycosylation in autoimmunity: A new potential treatment strategy

Frontiers in Immunology, 2022
Systemic lupus erythematosus (SLE) and primary Sjögren’s syndrome (pSS) are two autoimmune diseases characterised by the production of pathogenic autoreactive antibodies. Their aetiology is poorly understood. Nevertheless, they have been shown to involve

GlycoMAC: A Multiscale Metabolic‐Glycosylation Framework for Predicting Glycosylation Across Conditions in Mammalian Cell Cultures

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Antibody productivity and glycosylation quality in CHO cell cultures emerge from a dynamically evolving metabolic environment, yet existing models often work in isolation or at a single scale. Here, we present a multiscale mechanistic framework linking molecular, cellular, and macroscopic scales to predict how inputs shape bioprocess ...

The Role of Glycosylation in Melanoma Progression

Cells, 2021
Malignant melanoma is the most aggressive form of skin cancer, which originates from the malignant transformation of melanocytes, the melanin-producing cells of the skin.

Batch‐to‐Batch Optimization of pH Shifts in CHO Bioreactor Operations

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Culture pH is an important operating parameter in CHO cell cultures producing mAb since it directly affects growth and specific productivity. Mathematical models can be used to optimize the magnitude and timing of pH shifts provided that they are robust to model errors.

Effects of microRNAs on fucosyltransferase 8 (FUT8) expression in hepatocarcinoma cells. [PDF]

PLoS ONE, 2013
Fucosyltransferase 8 (FUT8) catalyzes the transfer of α1,6-linked fucose to the first N-acetylglucosamine in N-linked glycans (core fucosylation). Increased core fucosylation has been reported during hepatocarcinogenesis, in both cell-associated and ...

A genetic screen in Drosophila reveals the role of fucosylation in host susceptibility to Candida infection

Disease Models & Mechanisms, 2022
Candida infections constitute a blind spot in global public health as very few new anti-fungal drugs are being developed. Genetic surveys of host susceptibilities to such infections using mammalian models have certain disadvantages in that obtaining ...
