To identify the cells that occupied the nearly filled ventricular cavities of late-gestation E Using the myocardial marker MF, we confirmed that these cells were cardiomyocytes Fig.
To address the possibility that this phenotype might be secondary to increased proliferation of cardiomyocytes at an earlier stage, we stained heart sections for phosphorylated histone H3, an M-phase-specific marker, and found a marked increase in the number of positive-stained cells in the ventricular wall area of E Images were acquired using a confocal microscope.

The higher magnification images in B and D are demarcated in lower magnification panels. Herein we describe the first mouse model of GSD-IV disease. Using it, we identify the underlying mechanisms that lead to hydrops fetalis. The deficiency of Gbe1 led to reduced glycogen accumulation in developing hearts.
The fetal and infantile forms of GSD-IV are relatively rare. A complete absence of GBE1 enzyme activity results in the development of fetal hydrops and akinesia during the second trimester. Brain examinations of affected fetuses have shown intraventricular hemorrhage. Diastase-resistant amylopectin accumulates exclusively in fetal skeletal muscle cells and the heart, but not in the liver or neurons 5 However, the mechanisms responsible for human GSD-IV fetal hydrops and akinesia have remained unclear; notably, the structure and function of fetal hearts have not been examined in detail.
Several cases of perinatal neuromuscular forms of GSD-IV have been reported by different groups 71621 Severe hypotonia and dilated cardiomyopathy which were attributed to amylopectin deposits in cardiomyocytes with subsequent extensive injury of myocardial fibers leading to heart failure were observed in these cases 7.
Therefore, this model allowed us to investigate the early molecular events involved in the pathogenesis of fetal-type GSD-IV before cell death occurred. Cardiac glycogen is present at high levels during early-to-mid gestation before falling to low levels at the time of birth 24—26suggesting that glycogen might have a specific role in heart function and development.
However, the physiologic role of glycogen in the fetal heart is still not completely understood. It has been shown that glycogen plays an important role as an energy source for developing cardiac myocytes, allowing them to proliferate and function to support adequate circulation for the developing embryo In the present work, glycogen, which was highly accumulated in cardiomyocytes of E Heart rate was significantly decreased in E These results suggest that, in addition to serving as an energy reserve, cardiac glycogen might also play a critical role in regulating normal heart development and maturation.
A mouse model in which the ability to store glycogen in skeletal muscle and cardiac muscle was eliminated by disruption of the glycogen synthase 1 gene Gys1 as reported previously In these mice, glycogen was undetectable in cardiac muscle, and thin ventricular walls and reduced trabecular structures, attributable to a decrease in cell proliferation, were observed.
Ventricular trabeculation is one of the most critical steps of ventricular chamber development. The trabecular myocardium of embryonic mouse hearts rapidly expands during E9. The balance between proliferation and maturation is critical to the formation of a functionally competent ventricular wall.
Although the details of the molecular mechanisms responsible for cardiomyocyte hyperproliferation have not been fully examined, our findings provide a starting point for further investigation.
Furthermore, the possibility that physiologic and molecular changes in other organs e. In summary, using a gene-driven ENU-mutagenesis approach, we have generated a Gbe1-deficient mouse model that recapitulates the clinical features of hydrops fetalis and the embryonic lethality of severe fetal forms of GSD-IV.

| INTRODUCTION | Since glycogen is primarily stored in the liver or muscle tissue, glycogen storage diseases usually affect functioning of the liver, the muscles, or both. The glycogen storage diseases that mainly affect the liver are types I, III, IV, and VI. The glycogen storage diseases that mainly affect muscles are types V and VII. Type II affects nearly all organs, including the heart. Glycogen storage diseases are caused by a genetic enzyme defect that is inherited from both parents. Normally, enzymes help convert glucose into glycogen for storage. Other enzymes convert the glycogen back to glucose when quick energy is needed, as in exercise. In a person with a glycogen storage diseases, some of these enzymes are defective, deficient, or absent. Since glycogen storage diseases are hereditary, the primary risk factor for is having a family member with this disease. Glycogen storage disease symptoms in pediatric patients depend on its type. The following is a list of common glycogen storage disease symptoms:. Glycogen storage disease diagnosis usually occurs in infancy or childhood as a result of the above symptoms. If your child's doctor suspects a glycogen storage diseases, he or she will ask about your child's symptoms and medical history, then perform a physical exam. The doctor will perform tests to rule out or confirm the diagnosis. These tests may include:. Glycogen storage disease treatment will depend on the type of disease and the symptoms. The following general treatment guidelines apply to people who have glycogen storage diseases that affect the liver, or types I, III, IV, and VI. Your child's doctor will develop a treatment regimen based on your child's specific symptoms. This next group of glycogen storage disease treatment guidelines applies to people who have glycogen storage diseases that affect the muscles, or types V and VII. This is done by:. There is no way to prevent glycogen storage diseases. However, early treatment can help control the disease once a person has it. If you have a glycogen storage disease or a family history of the disorder, you can talk to a genetic counselor when deciding to have children. Learn about other Liver Disease States.

There is no specific treatment available, and the management of these patients is focused on the avoidance of hypoglycemia with frequent feedings with branched carbohydrates such as corn starch overnight. Symptoms of hypoglycemia typically improve as the child ages. Complications of liver involvement include fibrosis, hepatic adenomas, hepatocellular carcinoma, and rarely cirrhosis. GSD IIIa and IIIb have been shown to be associated with hyperlipidemia related to increased circulating free fatty acids. Additionally, GSD III has been shown to be associated with endothelial dysfunction. Patients with GSD III and muscle involvement may develop left ventricular hypertrophy related to intramyocardial glycogen deposition, which may be a focus for development of reentrant dysrhythmias. There have been case reports of sudden cardiac death in the setting of GSD III-related cardiomyopathy. To our knowledge this is the first case documenting premature atherosclerosis in a patient with GSD III. He had no other significant risk factors for having substantial coronary atherosclerosis at his age. Further studies are warranted to evaluate the incidence of early atherosclerotic heart disease in patients with GSD III who survive to adulthood. If patients with GSD III have an increased prevalence of coronary disease at a young age, then screening and preventative strategies will need to be considered. GSD III is a rare disorder of glycogen metabolism that is known to predispose patients to dyslipidemia and endothelial dysfunction. We report a case of premature atherosclerosis related to GSD III. Further studies investigating the prevalence of coronary disease in patients with GSD III are warranted. Sign in. Cath Lab Digest. EP Lab Digest. IO Learning. Journal of Invasive Cardiology.

ABSTRACT: The glycogen storage diseases are a rare form of inherited metabolic disease affecting intracellular glycogen metabolism, and several studies suggest glycogen storage disease GSD III predisposes patients to dyslipidemia and endothelial dysfunction. The presence of premature atherosclerotic heart disease in patients with GSD III has not been reported in the literature. We report a case of a year old patient with GSD III admitted with ventricular fibrillation cardiac arrest in the setting of anterior wall myocardial infarction. Further studies are warranted on the prevalence of atherosclerotic heart disease, and potential screening and preventative strategies, in this population of patients potentially at-risk for early cardiac events.

The cause of this rare disease is presumably an inborn error of metabolism transmitted as a recessive genetic character. Whatever the mechanism the condition is incompatible with life for more than a few months, during which cardiac function continually regresses. The most plausible explanation is that the accumulation of glycogen in the myocardial fibers progresses to a point where their contraction is impaired and effective cardiac action is no longer possible. It is pointed out that the term "glycogen storage disease of the heart" is a misnomer, since the disease process is not limited to this organ. On the other hand, as tradition has sanctioned its use, the name may well be retained. A plea is entered for dropping the name "von Gierke's disease of the heart" as leading to confusion with other types of glycogen storage disease. The clinical and metabolic differences between the hepatic and cardiac types of glycogen storage disease are detailed. Other conditions characterized by abnormally great accumulation of glycogen in the myocardium, such as congenital rhabdomyoma of the heart, socalled cardiomegalia glycogenica circumscripta, and occasional cases in which death is sudden though not always explained, are described and the differences with glycogen storage disease of the heart mentioned. Differential diagnosis is discussed and it is pointed out there are no pathognomonic signs or laboratory investigations, except for the histochemical demonstration of abnormal amounts of glycogen in the skeletal muscles. It is suggested that biopsy of skeletal muscle be performed in all cases in which unexplained enlargement of the heart in infancy occurs. This is essential in order to plan ante- and postmortem pathologic and chemical studies. Advertising Disclaimer ». Sign In or Create an Account. Search Close. Shopping Cart. Create Account.
