Wilson's disease (WD) is an autosomal recessive disorder that results in accumulation of copper in the liver as a consequence of mutations in the gene encoding the copper-transporting P-type ATPase (ATP7B). WD is a chronic liver disorder, and individuals with the disease present with a variety of complications, including steatosis, cholestasis, cirrhosis, and liver failure. Similar to patients ...

Wilson Disease (WD) usually presents in the first decades of life, although rare patients have a later presentation. We report the clinical features, diagnostic evaluation, and outcome with treatment of two septuagenarian siblings evaluated as part of a research trial for treatment of neurological WD. The index case was a 72-year-old woman who suffered progressive neurological disability, then ...

The copper efflux transporters ATP7A and ATP7B sequester intracellular copper into the vesicular secretory pathway for export from the cell. The influence of these transporters on the pharmacodynamics of cisplatin, carboplatin, and oxaliplatin was investigated using human Menkes' disease fibroblasts (Me32a) that do not express either transporter and sublines molecularly engineered to express ei...

Copper homeostasis abnormalities have been shown to be associated with Alzheimer's disease (AD), possibly by accelerating amyloid-β toxicity and plaque formation. The ATP7B gene plays a key role in controlling body copper balance. Our previous studies showed an association between ATP7B variants and AD risk. Among these variants, an intronic single nucleotide polymorphism, rs2147363, was associ...

OBJECTIVE This study evaluated the current state of patients with Wilson disease in central Japan. PATIENTS AND METHODS Between 1999 and 2007, 30 patients were diagnosed as having Wilson disease with an International Diagnostic Score of 4 or more. The phenotypes, genotypes and post-diagnostic courses of these patients were analyzed. RESULTS Twenty-six patients had ATP7B mutations responsibl...

Copper transporter 1 (CTR1), copper transporter 2 (CTR2), copper-transporting p-type adenosine triphosphatase 1 and 2 (ATP7A and ATP7B) are key mediators of cellular cisplatin, carboplatin and oxaliplatin accumulation. In this meta-analysis, we aimed to evaluate the relation of CTR1, CTR2, ATP7A and ATP7B to overall survival (OS), progression-free survival (PFS), disease-free survival (DFS) and...

BACKGROUND Oxaliplatin-based chemotherapy has been linked to the development of sinusoidal obstruction syndrome (SOS), which is detrimental to outcome after liver resection for colorectal liver metastases (CLM). The aim of this study was to determine how the expression of genes involved in the transport and metabolism of FOLFOX chemotherapy impacts on tissue injury in a murine model of CLM. M...

BACKGROUND Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by allelic variants in ATP7B gene. More than 500 distinct variants have been reported, the most common WD causing allelic variant in the patients from Central, Eastern, and Northern Europe is H1069Q. METHODS All Latvian patients with clinically confirmed WD were screened for the most common mutation ...

objective(s):  denaturing high performance liquid chromatography (dhplc) is a high throughput approach for screening dna sequence variations. to assess oven calibration, cartridge performance, buffer composition and stability, the wave low and high range mutation standards are employed to ensure reproducibility and accuracy of the chromatographic analysis. the purpose of this study was to provi...

background: wilson disease (wd) is caused by numerous pathogenic mutations of the atp7b gene. there are several mutation screening methods that can be used for the diagnosis and carrier detection of wd, however such methods are costly and time-consuming. therefore, other diagnostic methods should be used for urgent situations such as prenatal diagnosis. objective: to report common polymorphisms...
