Down-regulation of β-N-acetyl-D-glucosaminidase increases Akt1 activity in thyroid anaplastic cancer cells.
O-GlcNAcylation is a common and dynamic modification of intracellular proteins in which β-N-acetyl-glucosamine moieties are attached to hydroxyl groups of serine or threonine residues (O-GlcNAc). Accumulating evidence suggests the critical role of protein O-GlcNAcylation in signal transduction, transcriptional control, cell cycle regulation and protein degradation. However, the exact role of O-...
متن کاملSpectrophotometricAssayfor UrinaryN-Acetyl-f3-D-Glucosaminidase Activity
An improved assay for N-acetyl-/3-o-glucosaminidase activity in urine is described that involves (a) gel filtration to separate the enzyme from inhibitors in urine, (b) enzymic hydrolysis of p-nitrophenyl-N-acetyl-3-D-glucosaminide at pH 4.4, and (C) spectrophotometry of the liberated p-nitrophenylate. Measurements of activity of the enzyme in 58 urine specimens correlated closely (r = 0.9998) ...
متن کاملUrinary biomarker N-acetyl-β-D-glucosaminidase can predict severity of renal damage in diabetic nephropathy
BACKGROUND Diabetic nephropathy is a clinical diagnosis where proteinuria is present in a patient with diabetes. Early intervention can significantly improve the prognosis. However, imprecision of the currently available biomarkers have impaired effective therapies in a timely manner. Urinary N-acetyl-β-D-glucosaminidase (NAG) is excreted in abnormally high amounts in many renal diseases. The a...
متن کاملUrinary Activities of N-acetyl-β-D-glucosaminidase and Its Isoenzyme B in Cadmium-Exposed Rats
This paper aims to assess the relationship between the urinary activity of N-acetyl-β-D-glucosaminidase (NAG) and its isoenzyme B (NAG-B) and cadmium (Cd) concentration in the urine as well as to evaluate which of these lysosomal enzymes may be a more useful biomarker for the monitoring of Cd-induced tubular damage. For this purpose we have used an experimental model in rats chronically exposed...
متن کاملIs urinary N-acetyl-beta-D-glucosaminidase a marker of urological abnormality in children?
Abstract Background: Hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. Moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. Prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. The presence of hydronephrosis is not synonymou...
