Abstract
We show that latent oxalyl thioester surrogates are a powerful means to modify peptides and proteins in highly dilute conditions in purified aqueous media or in mixtures as complex as cell lysates. Designed to be shelf-stable reagents, they can be activated on demand to enable ligation reactions with peptide concentrations as low as a few hundred nM at rates approaching 30 M-1 s-1 .

Abstract
Prostate cancer is a complex disease that affects millions of men globally, predominantly in high human development index regions. Patients with localized disease at a low to intermediate risk of recurrence generally have a favourable outcome of 99% overall survival for 10 years if the disease is detected and treated at an early stage. Key genetic alterations include fusions of TMPRSS2 with ETS family genes, amplification of the MYC oncogene, deletion and/or mutation of PTEN and TP53 and, in advanced disease, amplification and/or mutation of the androgen receptor (AR). Prostate cancer is usually diagnosed by prostate biopsy prompted by a blood test to measure prostate-specific antigen levels and/or digital rectal examination. Treatment for localized disease includes active surveillance, radical prostatectomy or ablative radiotherapy as curative approaches. Men whose disease relapses after prostatectomy are treated with salvage radiotherapy and/or androgen deprivation therapy (ADT) for local relapse, or with ADT combined with chemotherapy or novel androgen signalling-targeted agents for systemic relapse. Advanced prostate cancer often progresses despite androgen ablation and is then considered castration-resistant and incurable. Current treatment options include AR-targeted agents, chemotherapy, radionuclides and the poly(ADP-ribose) inhibitor olaparib. Current research aims to improve prostate cancer detection, management and outcomes, including understanding the fundamental biology at all stages of the disease.

Abstract
Reactive oxygen species (ROS) can surely be considered as multifunctional biofactors within the cell. They are known to participate in regular cell functions, for example, as signal mediators, but overproduction under oxidative stress conditions leads to deleterious cellular effects, cell death and diverse pathological conditions. Peroxisomal function has long been linked to oxygen metabolism due to the high concentration of H(2)O(2)-generating oxidases in peroxisomes and their set of antioxidant enzymes, especially catalase. Still, mitochondria have been very much placed in the centre of ROS metabolism and oxidative stress. This review discusses novel findings concerning the relationship between ROS and peroxisomes, as they revealed to be a key player in the dynamic spin of ROS metabolism and oxidative injury. An overview of ROS generating enzymes as well as their antioxidant counterparts will be given, exemplifying the precise fine-tuning between the opposing systems. Various conditions in which the balance between generation and scavenging of ROS in peroxisomes is perturbed, for example, exogenous manipulation, ageing and peroxisomal disorders, are addressed. Furthermore, peroxisome-derived oxidative stress and its effect on mitochondria (and vice versa) are discussed, highlighting the close interrelationship of both organelles.

Abstract
PURPOSE To determine the efficacy of (L)-cysteine and (L)-2-oxothiazolidine-4-carboxylic acid (OTZ) in reducing urinary oxalate excretion under hyperoxaluric conditions and to determine whether by inclusion of glycolate in a standard diet, cysteine:glyoxylate adduct can be detected in hyperoxaluric rats given either compound. MATERIALS AND METHODS Hyperoxaluria (200% above basal) was induced 2 days prior to commencement of the studies and maintained throughout. After a 3 days baseline, animals were randomly allocated to a control or treatment group. Standard diet containing either (L)-cysteine or OTZ was then fed to the treatment groups for 5 days while standard diet alone was fed to the control groups. Urinary oxalate excretion was subsequently monitored and average daily rates were then compared with basal values. Plasma and urine were analyzed for adduct. RESULTS Both (L)-cysteine and OTZ significantly reduced urinary oxalate excretion relative to the basal hyperoxaluric level (28.6 +/- 1.5 micromol./day). While (L)-cysteine reduced oxalate excretion over the 5 day treatment period by only 7.82 +/- 1.39 micromol./day (27%), OTZ reduced it by 12.34 +/- 1.58 micromol./day (43%). Adduct could not be detected in plasma or urine in this study. CONCLUSIONS This study confirms that both (L)-cysteine and OTZ are effective in reducing urinary oxalate excretion under hyperoxaluric conditions, with OTZ being more effective than (L)-cysteine. These compounds were shown to be 3- to 4-fold more effective in reducing urinary oxalate excretion under hyperoxaluric conditions when compared with the results from previous studies under normooxaluric conditions.

Abstract
Oxidases are a widespread group of enzymes. They are present in numerous organisms and organs and in various tissues, cells, and subcellular compartments, such as mitochondria. An important source of oxidases, which is investigated and discussed in this study, are the (micro)peroxisomes. Oxidases share the ability to reduce molecular oxygen during oxidation of their substrate, yielding an oxidized product and hydrogen peroxide. Besides the hydrogen peroxide-catabolizing enzyme catalase, peroxisomes contain one or more hydrogen peroxide-generating oxidases, which participate in different metabolic pathways. During the last four decades, various methods have been developed and elaborated for the histochemical localization of the activities of these oxidases. These methods are based either on the reduction of soluble electron acceptors by oxidase activity or on the capture of hydrogen peroxide. Both methods yield a coloured and/or electron dense precipitate. The most reliable technique in peroxisomal oxidase histochemistry is the cerium salt capture method. This method is based on the direct capture of hydrogen peroxide by cerium ions to form a fine crystalline, insoluble, electron dense reaction product, cerium perhydroxide, which can be visualized for light microscopy with diaminobenzidine. With the use of this technique, it became clear that oxidase activities not only vary between different organisms, organs, and tissues, but that heterogeneity also exists between different cells and within cells, i.e. between individual peroxisomes. A literature review, and recent studies performed in our laboratory, show that peroxisomes are highly differentiated organelles with respect to the presence of active enzymes. This study gives an overview of the in situ distribution and heterogeneity of peroxisomal enzyme activities as detected by histochemical assays of the activities of catalase, and the peroxisomal oxidases D-amino acid oxidase, L-alpha-hydroxy acid oxidase, polyamine oxidase and uric acid oxidase.

Abstract
Oxalyl thiolesters, a group of putative intracellular regulators, have been shown to be in vitro inhibitors of some cytosolic enzymes which are stimulated by insulin. In this study, the effects of insulin and oxalyl thiolesters on pyruvate dehydrogenase, beta-oxidation, and acyl-CoA hydrolase activities in mitochondria from rat epididymal adipocytes are compared. Using glutathione, CoASH, cysteine, and cysteamine as thiol sources, oxalyl thioesters were synthesized, purified, and quantitated. Mitochondria were isolated from rat epididymal adipocytes, some of which were incubated with or without insulin. Mitochondrial activities were determined by radioisotopic assay subsequent to control, insulin, or oxalyl thiolester incubation. Under the conditions used in this study, pyruvate dehydrogenase activity was increased 28% subsequent to 10-min incubation of adipocytes with 400 microU/ml insulin; in contrast, preincubation of adipocyte mitochondria with S-oxalylglutathione resulted in a dose-dependent 11-19% inhibition of pyruvate dehydrogenase. S-oxalylglutathione also attenuated the spermine-induced activation of pyruvate dehydrogenase. Insulin treatment resulted in a small but significant increase in beta-oxidation of palmitic acid while 100 microM S-oxalylglutathione mediated a 40% decrease in palmitate oxidation. Palmitoyl-CoA hydrolase activity was decreased 14% by insulin treatment; however, S-oxalylglutathione caused a 14-50% increase in hydrolase activity. The other oxalyl thiolesters were not as effective or as consistent as S-oxalylglutathione in modulation of the mitochondrial activities; free thiols and oxalic acid did not modulate the activities. In summary, pyruvate dehydrogenase, palmitate beta-oxidation, and palmitoyl-CoA hydrolase activities in adipocyte mitochondria were modulated in approximately equal but opposite directions by insulin and S-oxalylglutathione. These findings support the suggestion that oxalyl thiolesters may function as an intracellular signal recruited to return insulin to normal levels.

Abstract
Despite the great effort that has gone into investigating urolithiasis, this condition still persists as one of the major ailments of the urinary tract. Calcium oxalate urolithiasis is the most common form, accounting for some 60 to 80% of total stones. This review examines the elements (i.e., urine volume and pH and urinary excretion of calcium, oxalate, citrate, urate, magnesium, pyrophosphate, and glycosaminoglycans) that give rise to idiopathic calcium oxalate urolithiasis. Treatment strategies for idiopathic calcium oxalate urolithiasis, including lithotripsy, also are discussed. Urinary oxalate excretion is a major risk factor for calcium oxalate urolithiasis, with 85 to 95% of the urinary load derived endogenously. The factors controlling endogenous oxalate production are reviewed, including pathways for the diversion of glyoxylate from oxalate production. The use of beta-aminothiols and other substances to reduce endogenous oxalate production in subjects with idiopathic calcium oxalate urolithiasis is also discussed. A review of current methodologies for the determination of urinary oxalate is also included.

Abstract
A convenient method is described for the quantitative analysis of oxalyl thiolesters (OTEs), a newly discovered class of mammalian metabolites, in biological samples. By this particular technique the total concentration of all OTEs in the sample is determined. The method involves first reacting the biological material with cysteamine (2-aminoethanethiol) or cysteine under conditions that convert OTEs quantitatively to N-oxalylcysteamine (or N-oxalylcysteine), followed by reaction with monobromobimane to give a highly fluorescent derivative that is analyzed by reversed-phase ion-pair chromatography, with tetrabutylammonium ion as the counterion and N-(2-mercaptopropionyl)glycine as an internal standard. The method is capable of detecting as little as 0.6 pmol of the bimane derivative of the N-oxalyl compound in a single HPLC injection. The application of this method has led to the discovery that not only OTEs but also N-oxalylcysteine and N-oxalylcysteamine are normal mammalian metabolites. In various rat tissues the OTE concentration ranges up to 65 nmol/g (wet wt), the N-oxalylcysteine concentration is approximately 10 nmol/g, and the N-oxalylcysteamine concentration is 0-3 nmol/g.

Abstract
With glycylglycine or water as acceptor, bovine kidney gamma-glutamyltransferase catalyzes reactions of the known mammalian metabolite, S-oxalylglutathione, at rates comparable to those of L-gamma-glutamyl-p-nitroanilide, a known good substrate. N-Oxalyl-cysteinylglycine is the eventual product of the former reaction. Since oxalyl thiolesters are implicated as important cell proliferation inhibitors, it is proposed that this reaction plays a major role in controlling cell proliferation.
