Kayser-Fleischer rings are a sign of Wilsons disease, which involves abnormal copper handling by the liver resulting in copper accumulation in the body and is characterised by abnormalities of the basal ganglia of the brain, liver cirrhosis, splenomegaly, involuntary movements, muscle rigidity, psychiatric disturbances, dystonia and dysphagia. The combination of neurological symptoms, a low blood ceruloplasmin level and KF rings is diagnostic of Wilsons disease.[1] Other causes of KF rings are cholestasis (obstruction of the bile ducts), primary biliary cirrhosis and cryptogenic cirrhosis (cirrhosis in which no cause can be identified).[1] ...

N2 - Wilsons disease protein (WNDP) is a copper-transporting P1-type ATPase which plays a key role in normal distribution of copper in a number of tissues, particularly in the liver and the brain. Copper has numerous effects on WNDP, altering its structure, activity, and intracellular localization. To better understand the function of this copper-transporting ATPase and its regulation by copper, we have recently developed the functional expression systems for WNDP and for Atox1, a cytosolic protein that serves as an intracellular donor of copper for WNDP. Here we summarize the results of our experiments on characterization of the enzymatic properties of WNDP and the effects of ...

CUCRU : The biliary system is the major pathway of copper excretion. Biliary excretion of copper requires an adenosine triphosphate (ATP)-dependent transporter protein. Mutations in the gene for the transporter protein cause hepatolenticular degeneration (Wilson disease). Ceruloplasmin, the primary copper-carrying protein in the blood, is also reduced in Wilson disease. Urine copper excretion is increased in Wilson disease due to a decreased serum binding of copper to ceruloplasmin, or due to allelic variances in cellular metal ion transporters.   Hypercupriuria is also found in hemochromatosis, biliary cirrhosis, thyrotoxicosis, various infections, and a variety of other acute, chronic, and malignant diseases (including leukemia). Urine copper concentrations are also elevated in patients taking contraceptives or estrogens and during pregnancy.   Low urine copper levels are seen in malnutrition, hypoproteinemias, malabsorption, and nephrotic syndrome. Increased zinc consumption interferes

The health care team will arrange for you to collect your childs urine over a 24 hour period.This will be explained in more detail when you are in clinic.They test the urine for copper levels. Excess copper in the eyes can cause dark rings to form around the iris. These are called Kayser-Fleischer rings. They are difficult to see without a special eye exam. Your childs doctor may do an eye exam to check for these rings. However, the absense of the Kayser-Fleischer rings does not rule out the disease. Your childs health care team may do other tests such as an ultrasound of the abdomen and a CT scan or MRI of the brain. ...

Background: Wilsons disease is an autosomal recessive genetic disorder resulting from an abnormality of copper metabolism. The excessive accumulation of copper in the brain induces an extrapyramidal syndrome. Oculomotor abnormalities occur in most extrapyramidal disorders but have rarely been studied in Wilsons disease. Objective: To evaluate the ocular motility manifestations of Wilsons disease. Methods: A prospective study of 34 patients affected by Wilsons disease who were recruited and their ocular motility recorded by electro-oculography (EOG). Results: Vertical smooth pursuit was abnormal in 29 patients (85%). Vertical optokinetic nystagmus and horizontal smooth pursuit were impaired in 41% and 41% of patients, respectively. No MRI abnormality was found in the lenticular nuclei of seven patients who manifested ocular motility abnormalities. Conclusion: Vertical eye movements, in particular vertical pursuits, are impaired in Wilsons disease, more often than vertical optokinetic ...

He was born in Cedarville, New Jersey. A year after Wilsons birth, his father died and his family moved to Edinburgh. In 1902 he graduated with an M.B. from the University of Edinburgh Medical School, and during the following year he received his B.Sc. in physiology. Afterwards he traveled to Paris, where he studied with neurologists Pierre Marie (1853-1940) and Joseph Babinski (1857-1932). In 1905 he relocated to London, where he worked as registrar and pathologist at the National Hospital, Queens Square. Later, he was appointed professor of neurology at Kings College Hospital. Wilson specialized in clinical neurology, and made important contributions in his studies of epilepsy, narcolepsy, apraxia and speech disorders. He described hepatolenticular degeneration in his Gold Medal winning M.D. dissertation of 1912 titled Progressive lenticular degeneration from the University of Edinburgh Medical School.[1] He was honored for his research of the disease, and afterwards the disorder became ...

In this report, we have determined serum transferrin (TF) and ceruloplasmin (CP) in patients with liver and renal diseases. Results indicate that TF in all hepatitis groups are significantly lower than that in the nor- mal group. The TF level in patients with abnormal GPT and positive HBsAg are significantly lower than that in normal persons. Therefore, the TF level may be referred to as an index for the hepatitis prognosis. The TF level in nephropathy patients are also lower than that in normal persons. Contents of CP in each group are not similar, for example in patients with hepatic carcinous (52.44±8.73mg％) are significantly higher than that in the normal group (46.75±7.92mg％), but there is no significant difference between hepatic B and normal group. Contents of CP in hepatolenticular degeneration are significantly lower than that in normal group (P 0.001). Therefore, measurement of CP which provides an available objective index is helpful to distingulsh the hepatocirrhosis

Clinical presentation and progression of Wilsons disease can be diverse in different groups of patients. While young children most likely to present with acute or chronic liver failure, older children and adults may exhibit extrahepatic manifestation like neuropsychiatric, cardiac, renal, pancreatic and several others. Diagnosis of Wilsons disease is based on the combination of specific clinical findings, laboratory and genetic testing. There are different modalities of treatment available for this condition. Liver transplantation has become a acceptable treatment option for acute and chronic liver failure related to Wilsons disease. It allows for resolution of metabolic disorder and hepatic disease progression. There are no definitive criteria and established outcomes in transplantation of the patients with Wilsons disease who have different degree of neuropsychiatric presentation. Therefore, it is very important to create specific criteria for selecting of these patients before transplantation and

After cellular uptake, Copper (Cu) ions are transferred from the chaperone Atox1 to the Wilson disease protein (ATP7B) for incorporation into Cu-dependent enzymes in the secretory pathway. Human ATP7B is a large multi-domain membrane-spanning protein which, in contrast to homologues in other organisms, has six similar cytoplasmic metal-binding domains (MBDs). The reason for multiple MBDs is proposed to be indirect modulation of enzymatic activity and it is thus intriguing that point mutations in MBDs can promote Wilson disease. We here investigated, in vitro and in silico, the biophysical consequences of clinically-observed Wilson disease mutations, G85V in MBD1 and G591D in MBD6, incorporated in domain 4. Because G85 and G591 correspond to a conserved Gly found in all MBDs, we introduced the mutations in the well-characterized MBD4. We found the mutations to dramatically reduce the MBD4 thermal stability, shifting the midpoint temperature of unfolding by more than 20 A degrees C. In contrast to ...

The aim of this study was to determine the risk for Bipolar Disorder (BD) in Wilsons disease (WD) and to measure the impaired Quality of Life (QL) in BD with WD using standardized psychiatric diagnostic tools and a case control design. This was a case control study. The cases were 23 consecutive patients with WD treated at the University Hospital in Cagliari, Italy, and the controls were 92 sex- and age-matched subjects with no diagnosis of WD who were randomly selected from a database used previously for an epidemiological study. Psychiatric diagnoses according to DSM-IV criteria were determined by physicians using structured interview tools (ANTAS-SCID). QL was measured by means of SF-12. Compared to controls, WD patients had lower scores on the SF-12 and higher lifetime prevalence of DSM-IV major depressive disorders (OR = 5.7, 95% CI 2.4-17.3) and bipolar disorders (OR = 12.9, 95% CI 3.6-46.3). BD was associated with lower SF-12 in WD patients. This study was the first to show an association

Why is improving Wilsons disease diagnosis important?. Wilsons disease is an inherited disease that leads to a build-up of copper in affected parts of the body. Diagnosis usually occurs in children or young adults, but has been seen in adults over 60 years of age. Copper build-up begins in the liver progressing over time to affect the brain; however, the challenge for doctors is that liver disease in Wilsons disease has non-specific features and standard liver blood tests may be normal, even with advanced scarring of the liver or cirrhosis. Early diagnosis allows earlier treatment, however, other causes of chronic liver disease may cause false-positive results and, depending on cut-off values used for testing, may result in further unnecessary testing. Conversely, false-negative results may also arise when a single-test strategy for diagnosis is used, possibly leading to a delay in treatment.. What is the aim and what was included in this review?. We aimed to examine the accuracy of three ...

Fulminant hepatic failure resulting from hepatitis E and coexistent Wilsons disease was diagnosed in a six year old girl six weeks after returning from a holiday in India. Wilsons disease was diagnosed on the basis of histological evidence of hepatocellular copper deposition, confirmed by biochemical estimation of liver copper concentration. Although severely damaged, the liver was non-cirrhotic. Hepatitis E virus (HEV) was diagnosed by nested polymerase chain reaction, the specificity of which was confirmed by direct sequencing of amplified DNA. Replication of HEV within the liver at the time of diagnosis was confirmed by selective amplification of the antigenomic strand of the virus obtained from total liver RNA. The patient had an orthotopic liver transplantation without recurrence of hepatitis and remains well at 19 months. Viral excretion, recorded by serial amplification of HEV RNA extracted from stool samples, persisted for 30 days after liver grafting. Severe vitiligo, present ...

Wilsons disease (WD) is an autosomal recessive disorder with reduced biliary excretion of copper plus impaired formation of ceruloplasmin, leading to copper accumulation in the liver, brain, kidney, and cornea. Clinical manifestations include liver damage, psychiatric symptoms, and neurological features. We report a 35-year-old woman with a history of deranged liver functions who had severe depression several years later and eventually presented with parkinsonian features. The underlying diagnosis is WD and family screening revealed WD in 2 other siblings. She could not tolerate penicillamine because of fever and leucopenia. While taking trientine hydrochloride and zinc sulphate, her parkinsonism improved and her depression remained in remission. WD should be considered in patients with unexplained liver function derangement or psychiatric symptoms. Early diagnosis and initiation of specific treatment are crucial in minimising any further cerebral and hepatic damage as well as securing possible ...

Wilson disease is an inherited disorder in which there is too much copper in the bodys tissues. The excess copper damages the liver and nervous system.

Abstract: Introduction: In Wilsons disease (WD), brain magnetic resonance images (MRI) show increased signal intensity in T2 weighted images in the lenticular nuclei, thalamus and brainstem, including the substantia nigra. A poor therapeutic response to levodopa in WD suggests the mechanism of a postsynaptic abnormality. However positron emission tomography studies show an involvement of the nigrostriatal presynaptic dopaminergic pathway. Case report: We report the clinical manifestations in a case of WD with akinetic-rigid syndrome and initial hesitation. The brain MRI showed an increased signal intensity lesion in the substantia nigra region, in addition to basal ganglion and thalamic lesions. However, dopamine transporter (DAT) imaging with 99mTc-TRODAT-1 revealed a nonsignificantly increased DAT uptake, suggesting a normal presynaptic nigrostriatal dopaminergic terminal. Conclusion: We suggest that significant heterogeneity can be found in WD patients and a normal presynaptic dopaminergic ...

Wilsons disease (WD) is a rare autosomal recessive disorder of copper metabolism. Data regarding WD is not available from Pakistan. A cross-sectional study was conducted at The Aga Khan University Hospital, Karachi, and all patients admitted with primary and secondary diagnosis of Wilsons disease were added. A total of 47 patients were seen; 68% (n = 32) were male. The mean age was 26.6 ± 9.97 years. Most of the patients presented with hepatic, (n = 22, 46.8%), neurological, (n = 17, 36.2%) and psychiatric (n = 8, 17%) symptoms. Mean ceruloplasmin level was 0.17 ± 0.13 g/dl; it was | 0.25 g/dl in 39 (86.6%) patients. Serum copper (Cu) was reduced in 32 (68.1%) patients and 24-hr-urinary Cu was raised in 22 (47.6%) patients. Slit lamp examination for Kayser-Fleischer (KF) rings was done on 15 (31.9%) patients and 9 (60%) of them had KF rings. Mean serum aspartate transaminase (AST) / alanine transaminases (ALT) ratio was 1.92 and median alkaline phosphatase / total bilirubin ratio was 79.30 (IQR 35

Wilson disease is a rare autosomal recessive inherited disorder of copper metabolism. The condition is characterized by excessive deposition of copper in the liver, brain, and other tissues.

Background: Wilson disease (WD) is characterized by hepatic copper accumulation with progressive liver damage to cirrhosis. This study aimed to characterize the toxic milk mouse from The Jackson Laboratory (Bar Harbor, ME, USA) (tx-j) mouse model of WD according to changes over time in hepatic copper concentrations, methionine metabolism, global DNA methylation, and gene expression from gestational day 17 (fetal) to adulthood (28 weeks). Methods: Included liver histology and relevant biochemical analyses including hepatic copper quantification, S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) liver levels, qPCR for transcript levels of genes relevant to methionine metabolism and liver damage, and DNA dot blot for global DNA methylation. Results: Hepatic copper was lower in tx-j fetuses but higher in weanling (three weeks) and adult tx-j mice compared to controls. S-adenosylhomocysteinase transcript levels were significantly lower at all time points, except at three weeks, correlating

Wilsons disease, with its varied clinical manifestations, often poses a diagnostic and therapeutic challenge.2 Scheinberg et al3 reported that early manifestations of WD are generally hepatic or neurological (40% each) while remainders present with psychiatric, haematological, renal, or osteochondrotic symptoms.. Various studies on diagnostic errors with specific clinical syndromes show that clinical diagnoses are incorrect at variable frequency.4-6 Walshe and Yealland7 analysed initial diagnosis of 136 patients of WD and observed that it fell into four groups-that is, organic disorder other than WD 25.7%, psychiatric illness 23.5%, seizure disorder 19.1%, and WD 31.6%. Incorrect diagnoses were as diverse as flat feet, myxoedema, myasthenia gravis, encephalitis, multiple sclerosis, Parkinsons disease, schizophrenia, depression, anxiety state, etc. They concluded, no two patients are ever the same, even in a sibship and there is no such thing as typical picture of Wilsons disease.

Wilson disease is an infrequent disorder worldwide in almost all populations. Frequencies of 1:30,000 to 1:40,000 are usually quoted (6), except for Crete and Sardinia with 6:100 and 1:7,000 live births respectively (7-8). At present, diagnosis of WD is extremely difficult especially for clinically asymptomatic individuals or those with atypical clinical manifestations. Moreover, different WD patients have different clinical features (9). Particularly, WD is representative of a low number of diseases that difficult to be treated; however, early diagnosis increases the probability of recovery (9).. Until now, more than 300 mutations have been reported in many different populations but a few of them show relative high frequencies in some geographic areas. The most frequent mutation in Europe is H1069Q with values over 65 % (10), in Sardinia, c.-441_- 427del accounts for 61.5 % of mutated chromosomes (8), mutation M645R is present in 55 % of patients in Spain (11), and R778L is very frequent in ...

Pathologic changes to the central nervous system in Wilson disease are always associated with a significant increase of tissue copper content. Excess copper may combine with sulfhydryl, carboxyl, or amine groups, resulting in improper enzymatic activity or damage to cellular structure.18 Despite the ubiquitous presence of toxic copper within the brain, pathologic findings are limited primarily to the basal ganglia, thalamus, and brain stem. Histopathologic studies have shown abnormalities throughout this system in patients with Wilson disease. These abnormalities include atrophy, spongy softening, cavitation, a general reduction of neurons, increased cellularity, and the presence of Opalski cells.19 The pathologic changes are presumed to result from an increased amount of extracellular copper, which causes oxidative stress and results in cell destruction.20-22.

Copper levels in brain in WD have been reported to be 10 to 15 fold normal values, depending on the different brain regions. Being very few data on copper distribution in central nervous system in WD available, it seemed of interest to study the concentration of copper and of other trace elements (Zn, P, Mg, Ca, Fe and S) in the brain of a patient died for WD. PROCEDURE: a 56 year old woman affected by WD was admitted to our hospital with signs of hepatic failure and died few days later. At autopsy, a brain slice extending from the left to the right hemisphere was divided in 28 samples. On each sample Copper, Iron, Magnesium, Phosphorus, Sulphur, Zinc and Calcium were determined by Induced Coupled Plasma Atomic Emission Spectroscopy. RESULTS: the mean concentration of copper, ranging from 88 to 158 microg/g of dry tissue in all the brain specimens ...

The research in the Svetlana Lutsenko Laboratory is focused on the molecular mechanisms that regulate copper concentration in normal and diseased human cells. Copper is essential for human cell homeostasis. It is required for embryonic development and neuronal function, and the disruption of copper transport in human cells results in severe multisystem disorders, such as Menkes disease and Wilsons disease. To understand the molecular mechanisms of copper homeostasis in normal and diseased human cells, we utilize a multidisciplinary approach involving biochemical and biophysical studies of molecules involved in copper transport, cell biological studies of copper signaling, and analysis of copper-induced pathologies using Wilsons disease gene knock-out mice.. Research Areas: biophysics, biochemistry, menkes disease, Wilsons disease, cell biology, multisystem disorders, physiology, copper, molecular biology ...

Wilson disease is an autosomal recessive disease caused by pathogenic variants in the gene ATP7B. While it is a pan-ethnic disease, it is found more frequently in individuals of Sephardic and Ashkenazi Jewish descent, as well as individuals from the Canary Islands and from Sardinia. As the protein encoded by ATP7B plays a role in copper transport, pathogenic variants in this gene result in the toxic accumulation of copper in different tissues in the body, particularly the liver, nervous system and eyes. Liver disease includes cirrhosis caused by chronic hepatitis, leading to liver failure. Copper depositions in the nervous system can cause neurologic symptoms including changes in behavior, parkinsonism, ataxia and dystonia, and psychiatric symptoms including anxiety, depression and psychosis. While the presence of two null variants is often associated with a more severe disease phenotype, the severity of the disease can vary within families, thereby making it difficult to predict disease ...

History of PBT2. Many Huntingtons disease families have been excited by word of a new player developing a novel treatment for HD. Prana Biotechnology, a drug development company in Australia, has developed a new drug they call PBT2.. HDBuzz has previously written about Prana and their drug, which works in a surprising and novel way. While all the details are not understood, the drug is designed to interfere with interactions between the huntingtin protein and the metal copper.. Interfering with copper in the body may sound like a strange and surprising way to attack Huntingtons disease, but there is a history of investigating changes in copper in the brain of HD patients.. Another genetic disease called Wilsons disease is caused by mutations in a gene that helps cells get rid of excess copper. The cells of patients with Wilsons disease accumulate too much copper because they dont know how to get rid of it, thanks to their defective gene.. It turns out that Wilsons disease patients have ...

Copper is an essential nutrient for sheep. Copper is required, but is also highly toxic. Copper is required for normal melanin production, elastin and collagen synthesis, iron metabolism, and the integrity of the nervous system. Copper is also known to be important for effective immune responses. The true importance of copper may be understood from looking at the problems associated with copper deficiency. Deficiencies are not often seen in the US. Common signs of copper deficiency are neonatal ataxia or swayback, degeneration of the myelin sheath of nerve fibers, and wool that lacks strength, crimp, elasticity, and pigment. Copper toxicity is more commonly seen and will prove to be more of a problem.. Copper Requirement. Copper is regularly used in the diet at about 8-11 parts per million. It may be toxic to sheep at 15-20 parts per million. There is a narrow difference between the amount of copper required and what will be toxic to the animal. A diet should never have copper level above 25 ...

Penicillamine is a chelating agent used in the treatment of Wilsons disease. It is also used to reduce cystine excretion in cystinuria and to treat patients with severe, active rheumatoid arthritis unresponsive to conventional therapy. Penicillamine is used as a form of immunosuppression to treat rheumatoid arthritis. It works by reducing numbers of T-lymphocytes, inhibiting macrophage function, decreasing IL-1, decreasing rheumatoid factor, and preventing collagen from cross-linking. Its use in Wilsons disease, a rare genetic disorder of copper metabolism, relies on its binding to accumulated copper and elimination through urine ...

birth defects. Exceeding the daily requirement is dangerous, however, because copper toxicity commonly occurs. Copper toxicity is a very serious medical problem. Acute toxicity due to ingestion of too much supplement, for example, may cause nausea, vomiting, abdominal pain, diarrhea, dizziness, headache, and a metallic taste in the mouth. Chronic toxicity is often caused by genetic defects of copper metabolism, such as Wilsons disease. In this disease, copper is not eliminated properly and is allowed to accumulate to toxic levels. Copper is therefore present at high concentration where it should not be, such as in the liver, the lens of the eye, kidneys, or brain.. Disease Prevention. Copper is a good antioxidant. It works together with an antioxidant enzyme, superoxide dismutase (SOD), to protect cell membranes from being destroyed by free radicals. Free radicals are any molecules that are missing one electron. Because this is an unbalanced and unstable state, a radical is desperately finding ...

In this paper we examine how the bacterial growth is influenced by the availability of copper ions in complex Mueller Hinton growth media. The data shows that the free copper concentration is seven to eight orders of magnitude lower the total copper concentration and that there seems to be a better correlation between the free copper concentration and bacterial growth, than for the total copper concentration and growth. Furthermore, it is shown that the initial pH influences the amount of free copper ions in the media and that this has a direct effect on the ability of bacterial cultures to grow. However, there still remains an effect of pH on bacterial growth which cannot be attributed to the influence of the Cu2+ concentration alone. The study also shows that the sterilization treatment can have some effect on the availability of copper ions in the media over time. Freshly autoclaved and sterile filtered media contain the same level of free copper ions and perform equally well in the ...

Vital youngsters who seem to be as athletic as any others begin to fail in skills. If one looks closely at the eyes, within the usual eye color, a ring of copper color is seen in most cases. A certain step in secreting copper in liver cells goes amiss. The copper builds up and damages the liver. Transport of spilled copper about the body goes wrong in that the usual transport protein does not get the proper access to the copper. Amino acids spill in the urine. The gene is recessive so it takes both parents as carriers in most cases. Attempts to pull out the building copper from the liver by chelation have unfortunately resulted in the copper being dumped moreso in the brain - especially one region where associative movements are organized at a high level. The result is bizzarre rigid postures of extreme stiffness.. More recent drugs - especially based on zinc - have turned this disease around neurologically. Combinations of neuromuscular procedures with background drug treatment of the disease ...

U.S. Rep. Frederica Wilson, D-Fla., continues to champion a proposal to vaccinate all non-medically exempted public school children across the nation.. Last week, Wilson brought back her Vaccinate All Children Act which would disallow states from offering non-medical exemptions for meeting school vaccine requirements. Under Wilsons proposal, children for whom immunization is medically safe would be required to be vaccinated in accordance with the recommendations of the Advisory Committee on Immunization Practices. Wilson championed a similar proposal back in 2015.. Wilson weighed in on her new bill on Tuesday.. The health and safety of children must be our top priority. Vaccines play an important role in keeping all children safe, especially those with compromised immune systems who rely on herd immunity to safeguard against potentially deadly viruses, said Wilson.. Research has shown that vaccination is an effective and necessary tool to guard against the spread of viruses. One dose ...

Artwork page for Landscape with Bathers, Cattle and Ruin, Richard Wilson, c.1770-5 This composition is one of numerous idealised landscapes by Wilson based on the scenery he had observed in Italy in the 1750s. The arrangement of classical buildings in an imaginary setting was a device Wilson had learnt from Claude. Unlike the earlier master, however, Wilson tended to include ancient buildings that were no longer intact, thereby evoking a sense of time past. The domed ruin in the centre of this view is derived from a building just outside Rome, known in the eighteenth century as the Temple of ...

Wilsons disease (WD) is an autosomal recessive disorder characterized by the functional disruption of the copper-transporting protein adenosine triphosphatase 7B (ATP-ase 7B). The disease is caused by mutations in ATP7B gene. It seems that the type of mutation in ATP7B only to some degree determines phenotypic manifestation of WD. We examined two pairs of monozygotic twins discordant for WD phenotype. The first set of twins were ATP7B compound heterozygotes c.3207C,A (p.H1069Q)/c.1211_1212insA (p.N404Kfs ...

We regularly see questionable information online concerning how to mosaic and how to do other art and craft projects. Mostly this information is questionable because it was written without regard to durability or how the project could have been used as an opportunity to make real art (personal, unique) instead of making clones of something already mass produced. Sometimes we even see instructions that are potentially dangerous or even likely to be dangerous. The recent fad of tiling floors with copper pennies may be an example of this, at least in certain situations.. In micro amounts, copper is a nutrient and is found in all plant and animal life. On the other hand, excessive exposure to copper can be toxic, particularly if a person has a genetic predisposition to a condition called Wilsons Disease, in which the liver is unable to remove excess copper from the body.. Sure we all handle copper pennies every day, but this is different from lining a living space with them, especially on a floor ...

Copper (Cu) is an essential metal required for activity of a number of redox active enzymes that participate in critical cellular pathways such as metabolism and cell signaling. Because it is also a toxic metal, Cu must be tightly controlled by a series of transporters and chaperone proteins that regulate Cu homeostasis. The critical nature of Cu is highlighted by the fact that mutations in Cu homeostasis genes cause pathologic conditions such as Menkes and Wilson diseases. While Cu homeostasis in highly affected tissues like the liver and brain is well understood, no study has probed the role of Cu in development of skeletal muscle, another tissue that often shows pathology in these conditions ...
