Alanine/glyoxylate aminotransferase 1 (AGT) is peroxisomal in most normal humans, but in some patients with the hereditary disease primary hyperoxaluria type 1 (PH1), AGT is mislocalized to the mitochondria. In an attempt to identify the sequences in AGT that mediate its targeting to peroxisomes, and to determine the mechanism by which AGT is mistargeted in PH1, we have studied the intracellular compartmentalization of various normal and mutant AGT polypeptides in normal human fibroblasts and cell lines with selective deficiencies of peroxisomal protein import, using immunofluorescence microscopy after intranuclear microinjection of AGT expression plasmids. The results show that AGT is imported into peroxisomes via the peroxisomal targeting sequence type 1 (PTS1) translocation pathway. Although the COOH-terminal KKL of human AGT was shown to be necessary for its peroxisomal import, this tripeptide was unable to direct the peroxisomal import of the bona fide peroxisomal protein firefly luciferase ...

Our objective was to conduct a long-term prospective longitudinal study to establish the incidence, clinical progression, and severity of hyperoxaluria after RYGB. Study Design: Patients undergoing RYGB between December 2005 and April 2007 provided 24-hour urine collections for comprehensive stone risk analysis 1 week before and 3 months and 1 and 2 years after surgery. Primary outcomes were changes in 24-hour urinary oxalate ...

Oxalate nephropathy is a rare disorder that can result in acute kidney injury (AKI) and progresses to end-stage kidney disease (ESKD). The causes can be either primary or secondary. Primary hyperoxaluria includes a group of hereditary disorders with enzymatic defects in the glyoxylate pathway, resulting in decreased oxalate metabolism. Secondary hyperoxaluria, often overlooked can result from increased intestinal absorption, nutritional deficiencies, decreased fluid intake, impaired excretion, and increased dietary consumption of oxalate. We present a Caucasian case of acute oxalate induced nephropathy associated with consumption of large quantities of green vegetables in a patient with chronic kidney disease (CKD). Imaging study showed no evidence of kidney stone, but a kidney biopsy revealed acute tubular injury, tubular atrophy, interstitial fibrosis, and dense tubular deposition of calcium oxalate crystals. Upon further questioning the patient, we learned that in the months prior to presentation, he

The primary hyperoxalurias are autosomal recessive disorders of glyoxylate metabolism characterized by excessive production and urinary excretion of oxalate and glycolate (Primary Hyperoxaluria type II, PH2) (see Figure 1).. The term primary hyperoxaluria was first used by Archer and colleagues in 1957 to specifically denote a suspected metabolic origin for the marked hyperoxaluria, recurrent urolithiasis and renal and extra-renal calcium oxalate crystal deposition that characterized affected children. The urine oxalate excretion rate in affected patients is typically 3 to 6 times normal with severe clinical consequences. Kidney stones and/or calcification of the kidney occur in childhood or adolescence. Renal injury due to oxalate and consequences of the stones often leads to renal failure. Loss of renal function, if not addressed promptly by transplantation, leads to markedly increased plasma concentrations of oxalate with deposition of calcium oxalate in body tissues. Resulting organ system ...

Primary hyperoxaluria type III is caused by mutations in DHDPSL, which encodes a protein which could synthesize glyoxalate, and activating mutations would increase glyoxalate and then oxalate accumulation.

Mutations in the alanine-glyoxylate amino transferase gene (AGXT) are responsible for primary hyperoxaluria type I, a rare disease characterized by excessive hepatic oxalate production that leads to renal failure. We generated a null mutant mouse by targeted mutagenesis of the homologous gene, Agxt, in embryonic stem cells. Mutant mice developed normally, and they exhibited hyperoxaluria and crystalluria. Approximately half of the male mice in mixed genetic background developed calcium oxalate urinary stones. Severe nephrocalcinosis and renal failure developed after enhancement of oxalate production by ethylene glycol administration. Hepatic expression of human AGT1, the protein encoded by AGXT, by adenoviral vector-mediated gene transfer in Agxt(-/-) mice normalized urinary oxalate excretion and prevented oxalate crystalluria. Subcellular fractionation and immunofluorescence studies revealed that, as in the human liver, the expressed wild-type human AGT1 was predominantly localized in mouse ...

Background: Primary hyperoxaluria type 1 (PH1) is caused by a deficiency of peroxisomal alanine:glyoxylate aminotransferase (AGT). In about one third of patients, enzymatically active AGT is synthesized but is mistargeted to mitochondria. There are more than 50 mutations identified in the gene for AGT. Four mutations, G170R, 33_34insC, F152I and I244T account for more than 50% of PH1 alleles. The question arose whether there are ethnic differences in PH1 genotype. Methods: The published data on mutations in the AGT gene were examined with respect to recurrences and geographic or ethnic association. The mutations that have been found in at least 2 unrelated individuals were considered. Results: Two common mutations, G170R and 33_34insC showed no obvious ethnic associations and have been found in a variety of populations. A third common PH1 mutation, I244T, has a strong association with people from a Spanish or North African background. A particularly high frequency among Canary Islands PH1 patients

The purpose of this study is to collect medical information from a large number of patients in many areas of the world with primary hyperoxaluria. This medical information will be entered into a registry to help the investigators compare similarities and differences in patients and their symptoms. The more patients that the investigators are able to enter into the registry, the more the investigators will be able to understand primary hyperoxaluria and learn better ways of treating patients with this disease. It is the investigators hope that by entering as many patients with PH as possible, the information that the investigators collect may help physicians diagnose patients sooner and determine what treatments may work best on patients with similar medical or genetic backgrounds ...

To the editor: The association of hyperoxaluria and nephrolithiasis secondary to disease and resection of the distal ileum was recently described by Smith, Fromm, and Hofmann (1). While with the U.S. Army at Red-stone Arsenal, Alabama, we observed a patient with marked hyperoxaluria and bilateral nephrolithiasis associated with a large Meckels diverticulum. After surgical resection of the diverticulum, urinary oxalate excretion returned to normal.. In March 1971, a 46-year-old man had spinal X rays for back pain that showed degenerative changes and bilateral nephrolithiasis confirmed by intravenous pyelogram. The patient gave no history of symptomatic renal calculi. Urinalysis, blood urea ...

Background: Primary hyperoxaluria type 1 (PH1) is rare but devastating autosomal recessive inherited disease and cause to graft failure after kidney transplant (KT). We report a case series and a comprehensive review of literature in order to review the AGXT mutations in Chinese population and discuss the genotype-outcome correlation of PH1.. Methods and Results: First we scanned the AGXT, GRHPR and HOGA1 genes for 6 Chinese families with PHs. Four novel variants in AGXT gene including p.Ala186Val, p.Gly41Trp, p.Lys12Gln fs and p.Leu33Met were identified and subsequent Western Blotting analysis showed the variants affected the function of AGT protein on different levels. ...

Bariatric surgery is associated with hyperoxaluria hence predisposing to nephrolithiasis. The present study aimed to investigate the underlying mechanisms contributing to increased urinary oxalate in a mini-gastric bypass (MGB) surgery model in rats under different dietary conditions. The expression of intestinal oxalate transporters was also evaluated. Male rats underwent MGB (n = 21) or Sham procedure (n = 21) and after recovery were fed a standard or high-fat diet with or without oxalate for 8 weeks. Stool and urine were collected before surgery (baseline) and at the end of protocol (final), when intestinal fragments were harvested for expression of Slc26a3 and Slc26a6 oxalate transporters. MGB groups fed with fat, irrespective of oxalate supplementation, presented steatorrhea. In MGB animals fed with fat and oxalate (Fat + Ox), final values of urinary oxalate and calcium oxalate supersaturation risk were markedly and significantly increased versus baseline or Sham animals under the same ...

A 24-year-old woman with end-stage renal failure because of primary hyperoxaluria type 1 was evaluated in our hospital for systemic calcium oxalate deposition in the course of long-term (5 years) hemodialysis therapy. Diagnosis of primary hyperoxaluria type 1, a hereditary cause of calcium oxalate kidney stones or progressive nephrocalcinosis that frequently results in end-stage renal failure,1 was made by liver biopsy (reduced alanine:glyoxylate aminotransferase activity, 3.0 µmol/h per milligram protein; normal, 19.1-47.9) and by genetic testing (homozygosity for the c.302 T,C, AGXT mutation). Her plasma oxalate level on regular hemodialysis (3× per week over 4 hours) was increased (86 µmol/L predialysis; normal, ,10 µmol/L).. Transthoracic echocardiography revealed increased wall thickness of the left ventricle (LV; Figure 1). The LV was mildly dilated and showed a decreased systolic function. Flow across the mitral valve demonstrated a restrictive filling pattern. Moreover, the ...

TY - JOUR. T1 - Neuropathy associated with hyperoxaluria. T2 - Improvement after combined renal and liver transplantations. AU - Galloway, Gloria. AU - Giuliani, Michael J.. AU - Burns, Dennis K.. AU - Lacomis, David. PY - 1998. Y1 - 1998. N2 - Little is known about oxaluria-associated neuropathy, and no effective treatments have been described. We report two patients with clinically severe and progressive sensorimotor polyneuropathy associated with oxaluria. Electrodiagnostic testing and sural nerve histopathology revealed evidence of severe axon loss and demyelination. In addition, birefringent crystalline deposits were identified within endoneurial and parineurial blood vessel walls, axon cylinders, and perimysial blood vessel walls. Electron probe microscopy confirmed that calcium (consistent with calcium oxalate) was a major constituent of the crystals. Both patients had substantial improvement in neuropathic signs and symptoms after kidney and liver transplantations despite no prior ...

Primary hyperoxaluria Type 1 is a rare autosomal recessive inborn error of glyoxylate metabolism, caused by a deficiency of the liver-specific enzyme alanine:glyoxylate aminotransferase. The disorder results in overproduction and excessive urinary excretion of oxalate, causing recurrent urolithiasis and nephrocalcinosis. As glomerular filtration rate declines due to progressive renal involvement, oxalate accumulates leading to systemic oxalosis. The diagnosis is based on clinical and sonographic findings, urine oxalate assessment, enzymology and/or DNA analysis. Early initiation of conservative treatment (high fluid intake, pyridoxine, inhibitors of calcium oxalate crystallization) aims at maintaining renal function. In chronic kidney disease Stages 4 and 5, the best outcomes to date were achieved with combined liver-kidney transplantation. « ...

Treatment is with a combined liver and renal transplantation (the liver is to rectify the enzyme deficiency, not because of liver failure).. The pyridoxine supplementation may be used in conjunction with combined liver-kidney transplantation to enhance the alternative pathway of glyoxylate metabolism to glycine and, therefore, reduce the amount of glyoxylate available for conversion to oxalate.. ...

Hyperoxaluria arises from either increased oxalate absorption from the gut or increased dietary intake of oxalate. Understanding the type of back pain that typically get how to not stones again kidney kidney stones as well as the additional symptoms associated with the condition can help to ensure sufferers seek immediate medical attention when symptoms arise. If you develop kidney stones, you may or may not experience symptoms, as the stones are so tiny in many people, they dont cause any problems. To dissolve cystine stones you need to have a large volume of urine because you need to lower cystine supersaturation below about 0.5.

This gene is expressed only in the liver and the encoded protein is localized mostly in the peroxisomes, where it is involved in glyoxylate detoxification. Mutations in this gene, some of which alter subcellular targetting, have been associated with type I primary hyperoxaluria. [provided by RefSeq, Jul 2008]

Increased urinary oxalate excretion (hyperoxaluria) promotes the formation of calcium oxalate crystals. Monogenic diseases due to hepatic enzyme deficiency result in chronic hyperoxaluria, promoting end-stage renal disease in children and young adults. Ethylene glycol poisoning also results in hyperoxaluria, promoting acute renal failure and frequently death. Stiripentol is an antiepileptic drug used to treat children affected by Dravet syndrome. It has been shown to inhibit neuronal lactate dehydrogenase 5 enzyme. As this isoenzyme is also the last step of hepatic oxalate production, we hypothesized that stiripentol would potentially reduce hepatic oxalate production and urine oxalate excretion. In vitro, stiripentol decreased the synthesis of oxalate by hepatocytes in a dose-dependent manner. In vivo, oral administration of stiripentol significantly reduced urine oxalate excretion in rats. Stiripentol protected the kidneys against calcium oxalate crystal deposits in acute ethylene glycol ...

1. We have measured the plasma oxalate concentration (P Ox ), urinary oxalate excretion (U Ox ), oxalate equilibrium distribution volume (ODV), oxalate metabolic pool size [(ODV) × (P Ox )], total plasma oxalate clearance (PC Ox ), renal (or dialyser) oxalate clearance (RC Ox ), non-renal oxalate clearance (NRC Ox ) and the tissue oxalate accretion rate (TOA)= [(NRC Ox ) × (P Ox )] in three patients with severe renal failure due to primary hyperoxaluria who were being treated by peritoneal dialysis or haemodialysis, or by renal transplantation. The clearance (either GFR or dialyser) of [ 99m Tc]diethylenetriaminepenta-acetate (DTPA) and the extracellular fluid volume (ECF) measured as [ 99m Tc]DTPA distribution volume were also determined. 2. Negligible amounts of 14 C were found in faeces or as 14 CO 2 in expired air and hence (NRC Ox ) = (PC Ox -RC Ox ). 3. Haemodialysis removed oxalate more efficiently than peritoneal dialysis in the patient where a direct comparison was possible. Neither ...

people eating a synthetic oxalate free high calcium diet (graph at left). As diet oxalate increased, urine oxalate rose from 0 to 10 mg/2500 kcal/d, urine oxalate rose steeply from 10 to 14 mg/gm urine creatinine. It rose more slowly, from 14 to barely 15 mg/gm urine creatinine as diet oxalate was increased to 50 mg/2500 kcal/d, and more or less at the same slope thereafter so that an increase from 50 mg/2500 kcal/d up to 250 mg/2500 kcal/d increased urine oxalate only from 14 to 18. The closed symbols are whole food the open symbols synthetic diets.. From this work the percent oxalate absorption could be calculated as around 10 - 15% and the contribution of diet oxalate to urine oxalate excretion as around 25 - 40% when intake of oxalate was between 50 and 350 mg/2500 kcal. Therefore one can consider a whole food 1000 mg calcium 50 mg oxalate as a usable low oxalate diet, and a 150 - 250 mg oxalate diet as relatively high.. The balance between diet calcium and diet oxalate does not matter ...

Oxalate, a non-essential end product of metabolism, causes hyperoxaluria and eventually calcium oxalate (CaOx) stone disease. Kidney cells exposed to oxalate stress results in generation of reactive oxygen species (ROS) and progression of stone formation. Perturbations in endoplasmic reticulum (ER) result in accumulation of misfolded proteins and Ca2+ ions homeostasis imbalance and serve as a common pathway for various diseases, including kidney disorders. ER stress induces up-regulation of pro-survival protein glucose-regulated protein 78 (GRP78) and pro-apoptotic signaling protein C/EBP homologous protein (CHOP). Since the association of oxalate toxicity and ER stress on renal cell damage is uncertain, the present study is an attempt to elucidate the interaction of GRP78 with oxalate by computational analysis and study the role of ER stress in oxalate-mediated apoptosis in vitro and in vivo. Molecular docking results showed that GRP78-oxalate/CaOx interaction takes place. Oxalate stress ...

Generally, cancer cells contain some metabolic mutation that favors rapid reproduction and the accumulation of biomass, and subsequently results in an increased uptake of both glutamine and glucose. In this paper, the authors further subcategorized cancer cells into primary glibolastomas and secondary glioblastomas. Primary glioblastomas tend to show deregulation of PI3K, which results in unbalanced growth factor throughout the cell. Secondary glioblastomas, on the other hand, tend to have mutations in Isocitrate dehydrogenase 1 (IDH1), which results in the accumulation of the oncometabolite 2-hydroxyglutarate (2-HG). The rapid uptake of glucose has traditionally been used to diagnose and quantify different cancers through the use of 18F-FDG PET imaging (where 18F-FDG is 18F-fluorodeoxygluocse, a fluorescing analog of glucose, and PET is positron emission tomography). This technique, however, is less effective at diagnosing cancer in the brain due to the high glucose metabolism naturally present ...

TANK Binding Kinase 1 (TBK1) is a non-canonical IkB kinase that contributes to KRAS-driven lung cancer. It is activated by phosphorylation of Serine-172 by TLR and RIG1 signaling, and this circuit triggers phosphorylation of IRF3 and IRF7, activation of NFκB and the expression of proinflammatory genes and interferons. In addition to its role role in regulating innate immunity, TBK1 also promotes oncogenesis by phosphorylating Akt and enhancing cell survival and by promoting autophagy and mitophagy. TBK1 is also induced under hypoxic conditions and expressed at significant levels in many solid tumors. TBK1 also contributes to prostate cancer dormancy and drug resistance by inhibiting mTOR and to tamoxifen resistance of breast cancer cells by enhancing transcriptional activity of ERα.. Recent studies from our lab revealed a novel role for TBK1 in regulating mitosis. It was found that levels of phospho-TBK1 increases and localizes to centrosomes and the mitotic spindles during mitosis. Depletion ...
