Reversible protein O-GlcNAc modification has emerged as an essential intracellular signaling system in several tissues, including cardiovascular pathophysiology related to diabetes and acute ischemic stress. We tested the hypothesis that cardiac O-GlcNAc signaling is altered in chronic cardiac hypertrophy and failure of different etiologies. Global protein O-GlcNAcylation and the main enzymes regulating O-GlcNAc, O-GlcNAc transferase (OGT), O-GlcNAcase (OGA), and glutamine-fructose-6-phosphate… 

Figures and Tables from this paper

Excessive O - GlcNAcylation causes heart failure and sudden death

Evidence is provided that excessive O-GlcNAcylation causes cardiomyopathy, at least in part, due to defective energetics, and Enhanced OGA activity is well tolerated and attenuation of O- GlcNA Cylation is an effective therapy against pressure overload induced heart failure.

Chronic O-GlcNAcylation and Diabetic Cardiomyopathy: The Bitterness of Glucose

The data show that excessive O-GlcNAcylation is a major trigger of the glucotoxic events that affect heart function under chronic hyperglycaemia, and pharmacological or genetic inhibition of the HBP in the diabetic heart improves heart function.

O-GlcNAcylation and cardiovascular disease.

The goal of this review is to provide an overview of some of the more recent advances in the understanding of the role O-GlcNAcylation plays in mediating cardiovascular function and disease.

Protein O-GlcNAcylation in cardiovascular diseases

The interactions between protein O-GlcNAcylation and CVD are focused on, and the potential molecular mechanisms that may be able to pave a new avenue for the treatment of cardiovascular events are discussed.

Fine-tuning the cardiac O-GlcNAcylation regulatory enzymes governs the functional and structural phenotype of the diabetic heart.

It is revealed that the modification of myocardial proteins by O-GlcNAc, a glucose-driven process, is not only increased in human diabetic myocardium, but correlates with reduced cardiac function in affected patients, and represents a novel therapeutic target for diabetes-induced heart failure.

Regulation of cardiac O-GlcNAcylation: More than just nutrient availability.

Cardiac O-GlcNAcylation blunts autophagic signaling in the diabetic heart.

Removal of Abnormal Myofilament O-GlcNAcylation Restores Ca2+ Sensitivity in Diabetic Cardiac Muscle

This study is the first to reveal that specific removal of O-GlcNAcylation restores myofilament response to Ca2+ in diabetic hearts and that altered O- GlcNA Cylation is due to the subcellular redistribution of OGT and OGA rather than to changes in their overall activities.

Protein O‐GlcNAcylation in the heart

This review focuses on the potential cardio-protective role of protein O-GlcNAcylation during ischemia-reperfusion injury, the deleterious consequences of chronically elevated O-glcNAc levels, the interplay between O- Glc NAcylation and phosphorylation in the cardiomyocytes, and the effects of O-GLcNACylation on other major non-myocyte cell types in the heart.



O-linked β-N-acetylglucosamine transferase is indispensable in the failing heart

Data provided provide keen insights into the pathophysiology of the failing heart and illuminate a previously unrecognized point of integration between metabolism and cardiac function in the failingheart.

Protein O-GlcNAcylation: a new signaling paradigm for the cardiovascular system.

The parallels between O-GlcNAc signaling and redox signaling, as an alternative paradigm for understanding the role of O- GlcNAcylation in regulating cell function, are explored.

Cardioprotection by N-Acetylglucosamine Linkage to Cellular Proteins

O-GlcNAc signaling represents a unique endogenously recruitable mechanism of cardioprotection that may involve direct modification of mitochondrial proteins critical for survival such as voltage-dependent anion channel.

O-GlcNAc Signaling in the Cardiovascular System

Evidence of protein O-GlcNAcylation as an autoprotective alarm or stress response in the cardiovascular system is highlighted and recent literature supporting the idea that promoting O- GlcNA Cylation improves cell survival during acute stress, whereas limiting it exacerbates cell damage in similar models is discussed.

O-Linked GlcNAc Modification of Cardiac Myofilament Proteins: A Novel Regulator of Myocardial Contractile Function

This study provides the first identification of O-GlcNAcylation sites in cardiac myofilament proteins and demonstrates their potential role in regulating myocardial contractile function.

Acute Regulation of Cardiac Metabolism by the Hexosamine Biosynthesis Pathway and Protein O-GlcNAcylation

Data demonstrate that acute modulation of H BP and protein O-GlcNAcylation in the heart stimulates fatty acid oxidation, possibly by increasing plasma membrane levels of FAT/CD36, raising the intriguing possibility that the HBP and O- GlcNAc turnover represent a novel, glucose dependent mechanism for regulating cardiac metabolism.

O-GlcNAc signaling attenuates ER stress-induced cardiomyocyte death.

It is concluded that enhanced O-GlcNAc signaling represents a partially proadaptive response to reduce ER stress-induced cell death and may partially explain a mechanism of O- GloverNAc-mediated cardioprotection.

Impact of Type 2 diabetes and aging on cardiomyocyte function and O-linked N-acetylglucosamine levels in the heart.

The notion that an increase in O-GlcNAc on specific proteins may contribute to impaired cardiomyocyte function in diabetes is supported, however, it is indicated that in the heart the level of O- Glc NAc on proteins appears to be differentially regulated by age and diabetes.

Swim-exercised mice show a decreased level of protein O-GlcNAcylation and expression of O-GlcNAc transferase in heart.

It appears that exercise-induced physiological hypertrophy is associated with a decrease in protein O-GlcNAcylation, which could potentially contribute to changes in gene expression and other physiological changes associated with exercise.
