Kidneys maintain internal milieu homeostasis through a well-regulated manipulation of body fluid composition. This task is performed by the correlation between structure and function in the nephron. Kidney diseases are chronic conditions impacting healthcare programs globally, and despite efforts, therapeutic options for its treatment are limited. The development of chronic degenerative diseases is associated with changes in protein O-GlcNAcylation, a post-translation modification involved in the regulation of diverse cell function. O-GlcNAcylation is regulated by the enzymatic balance between O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA) which add and remove GlcNAc residues on target proteins, respectively. Furthermore, the hexosamine biosynthetic pathway provides the substrate for protein O-GlcNAcylation. Beyond its physiological role, several reports indicate the participation of protein O-GlcNAcylation in cardiovascular, neurodegenerative, and metabolic diseases. In this review, we discuss the impact of protein O-GlcNAcylation on physiological renal function, disease conditions, and possible future directions in the field.

Aims: Glucosamine, a widely used dietary supplement, has been linked to potential cardiovascular risks, including atrial fibrillation (AF). This study aimed to investigate the effects of long-term glucosamine supplementation on AF susceptibility and the underlying mechanisms.

Materials And Methods: C57BL/6 J mice were treated with low-dose (15 mg/kg/day) or high-dose (250 mg/kg/day) glucosamine via drinking water for 6 weeks.

Genetic gradual reduction of OGT activity unveils the essential role of O-GlcNAc in the mouse embryo.

PLoS Genet

The reversible glycosylation of nuclear and cytoplasmic proteins (O-GlcNAcylation) is catalyzed by a single enzyme, namely O-GlcNAc transferase (OGT). The mammalian Ogt gene is X-linked, and it is essential for embryonic development and for the viability of proliferating cells. We perturbed OGT's function in vivo by creating a murine allelic series of four single amino acid substitutions, reducing OGT's catalytic activity to a range of degrees.

Focal Adhesion Kinase (FAK) is a non-receptor tyrosine kinase pivotal in cellular signal transduction, regulating cell adhesion, migration, growth, and survival. However, the regulatory mechanisms of FAK during tumorigenesis and progression still need to be fully understood. Our previous study demonstrated that -GlcNAcylation regulates integrin-mediated cell adhesion.

Vascular smooth muscle cells (VSMCs) undergo metabolic pathway transitions, including aerobic glycolysis, fatty acid oxidation, and amino acid metabolism, which are important for their function. Metabolic dysfunction in VSMCs can lead to age-related vascular diseases. -GlcNAcylation, a nutrient-dependent posttranslational modification linked specifically to glucose metabolism, plays an important role in this context.
