Wilson disease is a metabolic disorder with an autosomal recessive genetic pattern and occurs in 1-4 of every 100000 individuals. Inactivation of the ATP7B gene leads to accumulation of the toxic copper to liver and brain causing hepatic and neurological complication. Therefore, most patients suffer from chronic hepatic inflammation and central nervous system disorder. Nowadays, up to ...
Purpose: Resistance to platinum chemotherapy remains a significant problem in ovarian carcinoma. Here, we examined the biological mechanisms and therapeutic potential of targeting a critical platinum resistance gene, ATP7B, using both in vitro and in vivo models. Experimental Design: Expression of ATP7A and ATP7B was examined in ovarian cancer cell lines by real-time reverse transcription-PCR a...
جذب مس از طریق دستگاه گوارش به دقت تنظیم شده نمی باشد ولی دفع مس از طریق صفرا به شدت تنظیم شده می-باشد و این کار توسط یک گروه از پروتئین های انتقال دهنده مس وابسته به atp از جمله atp7b صورت می گیرد. این پروتئین توسط ژن atp7b برروی بازوی بلند کروموزوم 13 رمز می شود. کمبود این پروتئین باعث تجمع مس و بروز بیماری ویلسون می شود. بیماری ویلسون یک بیماری کبدی است که اغلب با علائم عصبی همراه می باشد و ...
Diagnosis of Wilson's disease (WD) still remains a challenge since no single test has an accuracy of 100%. Molecular testing for ATP7B gene mutations can help reach the diagnosis when routine testing is equivocal. We herein report an asymptomatic WD patient diagnosed accidentally by genetic analysis. Th is case suggests that WD is a challenge even in particular contexts such as family screening...
OBJECTIVE The objective of this study was to review the research on clinical genetics of Wilson's disease (WD). DATA SOURCES We searched documents from PubMed and Wanfang databases both in English and Chinese up to 2014 using the keywords WD in combination with genetic, ATP7B gene, gene mutation, genotype, phenotype. STUDY SELECTION Publications about the ATP7B gene and protein function ass...
As a relatively polar molecule, CDDP is thought to use specific plasma membrane systems for passage into cells, although entry by passive diffusion is also likely to occur. Alterations in these plasma membrane systems have been considered to be important resistance factors because one of the most consistent features of CDDP-resistant cell lines is decreased intracellular drug levels (1). Wherea...
Body copper homeostasis is regulated by the liver, which removes excess copper via bile. In Wilson's disease (WD), this function is disrupted due to inactivation of the copper transporter ATP7B resulting in hepatic copper overload. High urinary copper is a diagnostic feature of WD linked to liver malfunction; the mechanism behind urinary copper elevation is not fully understood. Using Positron ...
To the Editor: Drs. Lam and Mak, in a recent article in this journal (1 ), described the mechanisms leading to allele dropout in the PCR-based diagnosis of Wilson disease (WD) and reported potential solutions to this problem. We propose 2 strategies that would enable unequivocal and rapid identification of allele dropout in WD. In WD, an autosomal recessive disorder, mutations in the ATP7B gene...
Wilson's disease (WD) is an autosomal recessive disorder caused by mutations in the ATP7B resulting in copper overload in the liver and brain. Direct sequencing is routinely used to confirm WD diagnosis; however, partial and whole gene deletions in the heterozygous state cannot be detected by exon amplification since the normal allele will mask its presence. The aim of the present work was to s...
BACKGROUND Wilson disease is a rare autosomal recessive disorder of copper metabolism caused by mutation in the ATP7B gene. The combination of markers (such as SNPs) on a single chromosome can be used to understand the structure of haplotype in the human genome, in which provide notable information on the origin of the mutation in human genetic disorders. The purpose of this study was to determ...
