Preliminary data have been obtained indicating that glucose-6-phosphatase is inactivated upon preincubation with 447 and 224 mM acetaldehyde for 30 min at room temperature, resulting in a loss of 67% and 33% of the original activity, respectively. The reaction with acetaldehyde is rapid because 44%
Studies were performed to determine whether hypoglycemia or the glucagon response to hypoglycemia increases uric acid production in glycogen storage disease type I (glucose-6-phosphatase deficiency). Three adults with this disease had hyperuricemia (serum urate, 11.3-12.4 mg/dl) and reduced renal
Abnormal lipid transport is one of the more severe pathophysiological manifestations of glucose-6-phosphatase deficiency (glycogen storage disease, type I: GSD-I). To characterize further lipoprotein abnormalities in this inborn error of glycogen metabolism, we determined the levels of serum
An adult woman with hypoglycemia, hyperlactatemia, hyperuricemia, hypertriglyceridemia, hyperketonemia and inability to make new glucose from galactose, fructose, glycerol and alanine was found to have no hepatic glucose-6-phosphatase and deficient fructose-1,6-diphosphatase. Nonautonomous
Other investigators have shown that fructose infusion in normal man and rats acutely depletes hepatic ATP and P(i) and increases the rate of uric acid formation by the degradation of preformed nucleotides. We postulated that a similar mechanism of ATP depletion might be present in patients with
True reference values (TRV) should ultimately be determined in blood from inactive, unstimulated rats but in practice, acceptable reference values (ARV) may be established using blood from decapitated or anesthetized animals if one is cognizant of variations associated with blood sampling
Deficiency of glucose-6-phosphatase (G6Pase), a key enzyme in glucose homeostasis, causes glycogen storage disease type Ia (GSD-Ia), an autosomal recessive disorder characterized by growth retardation, hypoglycemia, hepatomegaly, nephromegaly, hyperlipidemia, hyperuricemia, and lactic acidemia.
Glycogen storage disease type Ia (GSD-Ia) is an autosomal recessive disorder of glycogen metabolism caused by glucose-6-phosphatase (G6Pase) deficiency. It is characterized by short stature, hepatomegaly, hypoglycemia, hyperuricemia, and lactic acidemia. Various mutations have been reported in the
Higher serum uric acid concentrations have been associated with higher bone mineral density (BMD) in observational studies of older men and perimenopausal or postmenopausal women, prompting speculation of a potential protective effect of uric acid on bone. Whether this relationship is present in the
Patients with osteosarcoma have poor prognosis and are often at high risk of death. Identification of prognostic biomarkers for osteosarcoma may aid in improving the survival. Hyperuricemia had been suggested as a poor prognostic factor of several cancers, but the prognostic role of hyperuricemia in
To investigate the effects of needling the Shu, Yuan, and Mu acupoints on serum uric acid (SUA), xanthine oxidase (XOD), and alkaline phosphatase (ALP) levels and the kidney index in a rat model of gout and hyperuricemia.Fifty rats were randomly divided Hyperuricemia (serum urate level >7 mg/dL) is caused by accelerated generation of uric acid and/or impaired excretion in the kidney. It is classified into three types (overproduction, underexcretion and mixed types). The typical cases with the type of uric acid overproduction are hypoxanthine
Glycogen storage disease type I (GSD-I) is a group of autosomal recessive disorders with an incidence of 1 in 100,000. The two major subtypes are GSD-Ia (MIM232200), caused by a deficiency of glucose-6-phosphatase (G6Pase), and GSD-Ib (MIM232220), caused by a deficiency in the glucose-6-phosphate
Glucose-6-phosphatase-alpha (G6PC) is a key enzyme in glucose homeostasis that catalyzes the hydrolysis of glucose-6-phosphate to glucose and phosphate in the terminal step of gluconeogenesis and glycogenolysis. Mutations in the G6PC gene, located on chromosome 17q21, result in glycogen storage
BACKGROUND
Increased frequencies of hyperuricemia and gout have been associated with primary hyperparathyroidism, and recent clinical trials of parathyroid hormone (PTH) have reported hyperuricemic adverse events. We evaluated the potential population impact of PTH on serum uric acid (SUA) levels by
