Abstract
Antibodies to double-stranded DNA (dsDNA) are prevalent in systemic lupus erythematosus (SLE), particularly in patients with lupus nephritis, yet the nature and regulation of antigenic cell-free DNA (cfDNA) are poorly understood. Null mutations in the secreted DNase DNASE1L3 cause human monogenic SLE with anti-dsDNA autoreactivity. We report that >50% of sporadic SLE patients with nephritis manifested reduced DNASE1L3 activity in circulation, which was associated with neutralizing autoantibodies to DNASE1L3. These patients had normal total plasma cfDNA levels but showed accumulation of cfDNA in circulating microparticles. Microparticle-associated cfDNA contained a higher fraction of longer polynucleosomal cfDNA fragments, which bound autoantibodies with higher affinity than mononucleosomal fragments. Autoantibodies to DNASE1L3-sensitive antigens on microparticles were prevalent in SLE nephritis patients and correlated with the accumulation of cfDNA in microparticles and with disease severity. DNASE1L3-sensitive antigens included DNA-associated proteins such as HMGB1. Our results reveal autoantibody-mediated impairment of DNASE1L3 activity as a common nongenetic mechanism facilitating anti-dsDNA autoreactivity in patients with severe sporadic SLE.

Abstract
OBJECTIVE Nephrolithiasis is one of the most common disorders of the urinary tract. The aim of this study was to examine a possible relationship between DNase I/II activity and E3 SUMO-protein ligase NSE2 in the sera of nephrolithiasis patients to evaluate the possibility of a new biomarker for evaluating kidney damage. METHODS Sixty nephrolithiasis patients and 50 control patients were enrolled in a case-control study. Their blood urea, creatinine, protein levels and DNase I/II activity levels were measured by spectrometry. Serum NSMCE2 levels were measured by ELISA. Blood was collected from patients of the government health clinics in Kuantan-Pahang and fulfilled the inclusion criteria. RESULTS The result indicated that mean levels of sera NSMCE2 have a significantly increase (P<0.01) in patients compared to control group. Compared with control subjects, activities and specific activities of serum DNase I and II were significantly elevated in nephrolithiasis patients (P$lt;0.01). CONCLUSION This study suggests that an increase in serum concentrations of DNase I/II and E3 SUMO-protein ligase NSE2 level can be used as indicators for the diagnosis of kidney injury in patients with nephrolithiasis.

Abstract
We have developed two microtiter plate assays to quantify the deoxyribonuclease activity in biological fluids. Both assays are based on hydrolysis of biotinylated and fluorescein-labeled DNA substrates, with subsequent immunochemical detection of non-digested DNA. The assay based on hydrolysis of 974 bp PCR product labeled with biotinylated forward and fluorescein-labeled reverse primers is more sensitive (0.05 U/ml) and convenient for quantifying the DNase activity in biological fluids than the assay based on hydrolysis of double-labeled 20 bp oligonucleotide. The DNase activity in urine and blood plasma of healthy donors was measured using the PCR product-based assay. Urine samples revealed greater activity, 1.49+/-1.41 U/ml; blood plasma DNase I-like activity was 0.36+/-0.20 U/ml. DNase II-like activity was not detected in the plasma samples. The data obtained confirm that DNase I-like enzymes are responsible for the majority of deoxyribonuclease activity in blood plasma.

Abstract
Deoxyribonuclease 1 (DNASE1, DNase I) and deoxyribonuclease 1-like 3 (DNASE1L3, DNase gamma, DNase Y, LS-DNase) are members of a DNASE1 protein family that is defined by similar biochemical properties such as Ca2+/Mg2+-dependency and an optimal pH of about 7.0 as well as by a high similarity in their nucleic acid and amino acid sequences. In the present study we describe the recombinant expression of rat Dnase1 and murine Dnase1l3 as fusion proteins tagged by their C-terminus to green fluorescent protein in NIH-3T3 fibroblasts and bovine lens epithelial cells. Both enzymes were translocated into the rough endoplasmic reticulum, transported along the entire secretory pathway and finally secreted into the cell culture medium. No nuclear occurrence of the nucleases was detectable. However, deletion of the N-terminal signal peptide of both nucleases resulted in a cytoplasmic and nuclear distribution of both fusion proteins. Dnase1 preferentially hydrolysed 'naked' plasmid DNA, whereas Dnase1l3 cleaved nuclear DNA with high activity. Dnase1l3 was able to cleave chromatin in an internucleosomal manner without proteolytic help. By contrast, Dnase1 was only able to achieve this cleavage pattern in the presence of proteases that hydrolysed chromatin-bound proteins. Detailed analysis of murine sera derived from Dnase1 knockout mice revealed that serum contains, besides the major serum nuclease Dnase1, an additional Dnase1l3-like nucleolytic activity, which, in co-operation with Dnase1, might help to suppress anti-DNA autoimmunity by degrading nuclear chromatin released from dying cells.

Abstract
A highly sensitive method for detecting deoxyribonucleases (DNases) I and II on an electrophoresed gel is described. A dried agarose film sheet containing DNA as a substrate and a buffer reagent was placed in contact with the gel surface after electrophoresis (DAFO method, Yasuda et al., Anal. Biochem. 1989, 183, 84-88). After an appropriate incubation period, the film sheet was peeled off and stained with SYBR-Green I (SG), and then the DNase isozyme bands were detected using a fluorescence image analyzer. We could detect pg levels of the DNases (DNase I, 2 pg; DNase II, 2pg), which represents a 32- to 128-fold increase in sensitivity compared with the original DAFO method using ethidium bromide (EB) as the fluorescent dye. A combination of this new detection method and isoelectric focusing electrophoresis in polyacrylamide gel allowed accurate DNase I typing from 1 microL human serum. This new technique has been named SG-DAFO, after its original dried agarose film overlay method using EB (EB-DAFO).

Abstract
In vitro selection experiments have produced nucleic acid ligands (aptamers) that bind tightly and specifically to a great variety of target biomolecules. The utility of aptamers is often limited by their vulnerability to nucleases present in biological materials. One way to circumvent this problem is to select an aptamer that binds the enantiomer of the target, then synthesize the enantiomer of the aptamer as a nuclease-insensitive ligand of the normal target. We have so identified a mirror-image single-stranded DNA that binds the peptide hormone vasopressin and have demonstrated its stability to nucleases and its bioactivity as a vasopressin antagonist in cell culture.

Abstract
The objectives of this study were to elucidate the genetic basis of human deoxyribonuclease II (DNase II) and to evaluate its usefulness as a genetic and/or diagnostic marker. We have devised a novel, specific and highly sensitive assay method for the urinary and leukocytic enzymes (Yasuda et al. 1991). The distribution of the activities of both enzymes displayed clear-cut bimodality and the Japanese study population could be classified into two distinct types, namely low-activity (DNASE2 L) and high-activity (DNASE2 H), which indicates the existence of a genetic polymorphism in the activity levels of urinary and leukocytic DNase IIs. Close correlations between the leukocytic and urinary enzyme activity levels from the same individuals were observed and the types in the leukocyte samples agreed with the types found in the corresponding urine samples. In a population study of 528 unrelated Japanese individuals, the gene frequencies of the low activity (DNASE2*L) and the high activity (DNASE2*H) alleles were calculated to be 0.632 and 0.368, respectively. The sex and age of individuals did not affect the distribution of DNase II activity levels. The family study results were compatible with the model that the low activity type is due to an autosomal recessive gene, which indicates that DNASE2 L represents homozygosity for DNASE2*L and DNASE2 H corresponds to homozygosity for DNASE2*H and heterozygosity for DNASE2*L and DNASE2*H.

Abstract
An endonuclease that specifically removes 8-hydroxyguanine (oh8Gua) from DNA has been isolated from Escherichia coli. As the amount of oh8Gua produced in DNA of X-ray-irradiated mice is known to decrease with time after irradiation, an attempt was made to find a similar activity in human polymorphonuclear neutrophils (PMNs) using a synthetic dsDNA containing oh8Gua as a substrate. The PMN enzyme was isolated free of other DNases, and found to cleave the substrate DNA simultaneously at 2 sites, the phosphodiester bonds 5' and 3' to oh8Gua, producing free hydroxyl and phosphate groups, respectively. The enzyme showed almost no activity on DNAs containing other kinds of modified base tested or mismatched DNA. Thus human cells also contain an endonuclease that specifically removes oh8Gua residues from DNA.

Abstract
Activity of acid DNAase (DNAase II) was shown to decrease in neutrophils from peripheric blood of patients with systemic lupus erythematosus as well as in macrophages of liver tissue from mice of the F1(NZB/w) strain during development of the lupus syndrome. Inhibition of the DNAase II activity in phagocytic cells might be among the reasons of accumulation of extracellular highly polymeric DNA in blood of the patients with systemic lupus erythematosus and to play a definite role in pathogenesis of the disease.

Abstract
We have detected Ca2+, Mg2+-dependent endonuclease activity in spleen cells of normal, Friend erythroleukemic, and phenylhydrazine-treated mice. When nuclei were isolated and incubated in the presence of Ca2+ and Mg2+ ions, the activity resulted in the production of 3'-OH termini in the cellular DNA and the release of chromatin due to internucleosomal DNA fragmentation. This enzyme activity was chromatin-bound and could be extracted from chromatin in an active form in 0.35 M KCl. The majority of endonuclease activity from erythroleukemic spleens was present in nuclei of precursor erythroid cells of low buoyant density (1.025-1.05 g/ml). Uninfected normal splenic tissue contained an endonuclease activity which was almost entirely confined to a B-lymphocyte population of high buoyant density (greater than 1.07 g/ml). Erythroid cell-enriched spleens from phenylhydrazine-treated mice exhibited a distribution of endonuclease activity in cells at low and high densities reflecting a mixture of erythroid and lymphoid cells. Cloned erythroleukemic cell lines propagated in vitro lacked cells of low density and showed no detectable endonuclease activity. However, nuclei from these cell lines were susceptible to exogenously added endonuclease extracted from erythroleukemic spleen cells. These same cell lines propagated as subcutaneous tumors contained endonuclease activity and a morphologically-similar low-density cell population which accounted for the endonuclease activity in these tumors. Nuclei from cloned lymphoid cell lines, representing different B-lymphocyte phenotypes, showed differences in the presence of endonuclease activity. Among the cell lines tested, only those expressing late B-cell markers showed detectable endonuclease activity.
