Abstract
Kidney disease is a general term for heterogeneous damage that affects the function and the structure of the kidneys. The rising incidence of kidney diseases represents a considerable burden on the healthcare system, so the development of new drugs and the identification of novel therapeutic targets are urgently needed. The pathophysiology of kidney diseases is complex and involves multiple processes, including inflammation, autophagy, cell-cycle progression, and oxidative stress. Heme oxygenase-1 (HO-1), an enzyme involved in the process of heme degradation, has attracted widespread attention in recent years due to its cytoprotective properties. As an enzyme with known anti-oxidative functions, HO-1 plays an indispensable role in the regulation of oxidative stress and is involved in the pathogenesis of several kidney diseases. Moreover, current studies have revealed that HO-1 can affect cell proliferation, cell maturation, and other metabolic processes, thereby altering the function of immune cells. Many strategies, such as the administration of HO-1-overexpressing macrophages, use of phytochemicals, and carbon monoxide-based therapies, have been developed to target HO-1 in a variety of nephropathological animal models, indicating that HO-1 is a promising protein for the treatment of kidney diseases. Here, we briefly review the effects of HO-1 induction on specific immune cell populations with the aim of exploring the potential therapeutic roles of HO-1 and designing HO-1-based therapeutic strategies for the treatment of kidney diseases.

Antroquinonol mitigates an accelerated and progressive IgA nephropathy model in mice by activating the Nrf2 pathway and inhibiting T cells and NLRP3 inflammasome. Free Radic Biol Med 2013; 61:285-97.

Abstract
High levels of reactive oxygen species (ROS), systemic T cell activation, and macrophage infiltration in the kidney are implicated in the acceleration and progression of IgA nephropathy (IgAN), the most frequent type of primary glomerulonephritis. However, the pathogenic mechanism of IgAN is still little understood, and it remains a challenge to establish a specific therapeutic strategy for this type of glomerular disorder. Recently, we showed that antroquinonol (Antroq), a pure active compound from Antrodia camphorata mycelium, inhibits renal inflammation and reduces oxidative stress in a mouse model of renal fibrosis. But the anti-inflammatory and immune-regulatory effects of Antroq on the acceleration and progression of primary glomerular disorders have not been determined. In this study, we show that Antroq administration substantially impeded the development of severe renal lesions, such as intense glomerular proliferation, crescents, sclerosis, and periglomerular interstitial inflammation, in mice with induced accelerated and progressive IgAN (AcP-IgAN). Further mechanistic analysis in AcP-IgAN mice showed that, early in the developmental stage of the AcP-IgAN model, Antroq promoted the Nrf2 antioxidant pathway and inhibited the activation of T cells and NLRP3 inflammasome. Significantly improved proteinuria/renal function and histopathology in AcP-IgAN mice of an established stage supported potential therapeutic effects of Antroq on the disease. In addition, Antroq was shown to inhibit activation of NLRP3 inflammasome in vitro by an IgA immune complex (IC) partly involving a reduced ROS production in IgA-IC-primed macrophages, and this finding may be helpful in the understanding of the mode of action of Antroq in the treated AcP-IgAN mice.

Abstract
BACKGROUNDS IgA nephropathy (IgAN) is the most common primary glomerulonephritis causing end stage renal disease (ESRD), and vasculopathy is known to involve disease progression. Klotho, a gene related to aging, has been reported to play a role in atherosclerosis and endothelial dysfunction. We investigated whether klotho gene polymorphism affect clinical course of IgAN. METHODS The data registered for PREMIER study which enrolled the patients with biopsy proven IgAN were analyzed. Two single nucleotide polymorphisms for klotho gene, G395A of promoter region and C1818T of exon 4, were examined, and investigated the association klotho genotypes with the progression of IgAN and patient survival. RESULTS Clinical data from 973 patients confirmed about survival were analyzed. The allele frequency was 0.830 and 0.170 for allele G and A, and 0.816 and 0.184 for allele C and T, which were complied with Hardy-Weinberg equilibrium (p=0.996 and 0.531 respectively). Death was observed more frequently in A-allele carriers of G395A polymorphism (0.7 vs. 2.6 %, GG vs. GA+AA, p=0.022). Renal survival in Kaplan-Meier survival curve was also worse in same group (p=0.04). CONCLUSION Klotho gene polymorphism was associated with patient survival and disease progression of IgAN.

Abstract
The induction of heme oxygenase-1 (HO-1) ameliorates oxidative stress and inflammatory process, which play important roles in IgA nephropathy. We hypothesized length polymorphism in the promoter region of the HO-1 gene, which is related to the level of gene transcription, is associated with disease severity of IgA nephropathy. The subjects comprised 916 patients with IgA nephropathy and gene data. Renal impairment was defined as an estimated glomerular filtration rate less than 60 mL/min/1.73 m(2) at diagnosis. The short (S: <23), medium (M: 23-28), and long (L: >28) (GT) repeats in the HO-1 gene was determined. The frequencies of S/S, S/M, M/M, S/L, L/M, and L/L genotypes were 7.2%, 6.9%, 3.1%, 30.8%, 22.7%, and 29.4%, respectively. The baseline characteristics were not different. In the S/S genotypic group, the renal impairment rate was 18.2%, which was lower than 32.2% in the group with M/M, L/M, or L/L genotype. The odds ratio of renal impairment in S/S genotype, compared to that in M/M, L/M, or L/L genotype, was 0.216 (95% confidence interval, 0.060-0.774, p=0.019). The HO-1 gene promoter length polymorphism was related to the renal impairment of IgA nephropathy at diagnosis, which is an important risk factor for mortality in IgA nephropathy patients.

Abstract
Oxidative stress plays various roles in the development and progression of IgA nephropathy, while bilirubin is known as a potent antioxidant. We therefore hypothesized that serum bilirubin would be associated with renal prognosis in IgA nephropathy. The study subjects comprised 1,458 adult patients with primary IgA nephropathy in Korea. We grouped patients according to the following quartile levels of bilirubin: <0.4 mg/dL (Q1), 0.4-0.5 mg/dL (Q2), 0.6-0.7 mg/dL (Q3), and >0.8 mg/dL (Q4). The outcome data were obtained from the Korean Registry of end-stage renal disease (ESRD). Eighty patients (5.5%) contracted ESRD during a mean follow-up period of 44.9 months. The ESRD incidences were 10.7% in Q1, 8.2% in Q2, 2.8% in Q3, and 2.8% in Q4 (p<0.001). The relative risk of ESRD compared to that in Q1 was 0.307 (95% confidence interval [CI], 0.126-0.751) in Q3 and 0.315 (95% CI, 0.130-0.765) in Q4. The differences of ESRD incidence were greater in subgroups of males and of patients aged 35 yr or more, with serum albumin 4.0 g/dL or more, with normotension, with eGFR 60 mL/min/1.73 m(2) or more, and with proteinuria less then 3+ by dipstick test. In conclusion, higher bilirubin level was negatively associated with ESRD incidence in IgA nephropathy.

Abstract
Aggregation is one of the important issues encountered during the development of immunoglobulin-based drugs. The aim of the current review is to discuss the causes and consequences of immunoglobulin aggregation as well as the relevance of immunoglobulin aggregation to disease pathogenesis. Extracellular deposition of immunoglobulins, either monoclonal light chains or intact polyclonal antibodies, induces renal failure in various nephropathies. The aggregates can present fibrillar or amorphous structures. In this review, factors known to influence protein aggregation, such as the primary structure of the protein, local environment and glycosylation are assessed, as well as the subsequent altered clearance, fibril formation and toxicity. The role of the protein local environment is emphasized. Even if the local environment causes only minor perturbations in the protein structure, these perturbations might be sufficient to trigger aggregate formation. This fact underlines the importance of choosing appropriate formulations for protein drugs. If the formulation provides a slightly destabilizing environment to the protein, the long-term stability of the drug may be compromised by aggregate formation.

Abstract
IgA nephropathy (IgAN) is characterized by predominant mesangial polymeric IgA1 (pIgA1) deposits, with increased plasma IgA1 levels. Plasma IgA levels are determined by the rate of IgA production, uptake by leukocytes, and removal by hepatocytes. Fc(alpha) receptor 1 (Fc(alpha)R1) is a candidate molecule for the regulation of IgA levels, but reports of its expression in leukocytes in IgAN are conflicting. Increased binding of endogenous IgA to circulating granulocytes and monocytes in IgAN was demonstrated in this study. Fc(alpha)R1 expression on leukocytes was increased, independently of plasma IgA levels. Fc(alpha)R1 was not saturated in leukocytes, because of internalization of IgA after uptake. Further binding of exogenous IgA isolated from individual subjects was observed with leukocytes from the same subjects. Compared with cells from control subjects, granulocytes but not monocytes from patients with IgAN exhibited a greater binding capacity for exogenous IgA, predominantly pIgA. To circumvent the possibility that endogenous IgA might alter Fc(alpha)R1 expression, granulocytes or monocytes derived from the HL-60 or U937 cell lines were used to explore the nature of IgA binding. A higher affinity for pIgA was demonstrated. Inhibition studies using unlabeled IgA, other serum proteins, or a specific Fc(alpha)R1-blocking antibody suggested binding mechanisms other than Fc(alpha)R1 for pIgA uptake by leukocytes. This study also suggested the migration and/or sequestration of "activated" leukocytes with predominant lambda-IgA in the mononuclear phagocytic system or inflammatory tissues, after the initial binding of lambda-pIgA. These immunologic abnormalities might contribute to the glomerulointerstitial injury in IgAN, in the presence of leukocytic infiltration.

Abstract
Using quantitative sandwich ELISA, we studied 27 patients with IgA nephropathy to determine whether the levels of urinary IL-8 might reflect the disease activity. The levels of urinary IL-8 in patients with advanced stage IgA nephropathy were significantly higher than those in the patients with the mild stage of this disease, or in the healthy controls. The results showed a positive significant correlation between the levels of IL-8 and disease activity, i.e., between levels of urinary protein and urinary casts. A significant correlation between levels of urinary IL-8 and tubular function damage was also found. It was thus suggested that measurement of urinary IL-8 might be useful in evaluating the degree of renal injuries and/or prognosis in patients with IgA nephropathy.

Abstract
Superoxide dismutase (SOD) in renal tissue biopsy specimens obtained from patients with immunoglobulin A nephropathy (13 cases) and non-immunoglobulin A mesangial proliferative glomerulonephritis (nine cases) was studied at the protein level by an enzyme-linked immunosorbent assay method and at the mRNA level by the reverse transcriptase-polymerase chain reaction (RT-PCR) assay. Total SOD activity in the tissue supernatant was measured by applying an electron paramagnetic resonance/spin trapping method. Normal renal tissues obtained from kidneys removed for malignancies (six cases) were included as healthy controls. The copper and zinc form of SOD (Cu,Zn-SOD) activity at both the protein and mRNA levels was lower in the moderately or severely damaged tissues compared with that in the normal or mildly damaged tissues. On the other hand, manganese SOD (Mn-SOD) values at either the protein level or the mRNA level did not differ significantly between control and patient samples. In the histochemical study using a polyclonal rabbit anti-Cu,Zn-SOD antibody, the staining intensity for Cu,Zn-SOD antigen was lower in the areas with advanced histologic damage than in the intact tissues. A follow-up study showed that renal function deterioration was proportionately slower in patients whose SOD activity was within the range of healthy tissue levels at the time of biopsy. Our data suggest that a lower level of SOD activity, whether as a cause or a consequence of the disease process, might induce a decrease in the scavenger reaction of superoxide (O2-) thus causing the tissue to become more vulnerable to oxidative stress.

Abstract
The pathogenesis of steroid-sensitive nephrotic syndrome (SSNS) is poorly defined. We previously demonstrated that monocytes from SSNS patients with proteinuria were activated to display exaggerated phagocytosis of opsonized particles and paradoxically reduced chemotaxis. In this study, we evaluated the capacity of hydrogen peroxide (H2O2) release from monocytes in 19 patients with SSNS and 13 healthy controls, by exposure to phorbol myristate acetate (PMA), using scopoletin method. Of 19 patients of SSNS, 7 were proteinuric and 12 in remission. The H2O2 release was significantly higher in SSNS patients with proteinuria than those in remission or normal controls [177.49 +/- 94.75 (mean +/- S.D.) vs. 60.67 +/- 58.89 (p < 0.02) or 85.02 +/- 48.62 nmol/90 min/mg cell protein (p < 0.05)]. Follow-up measurements in two SSNS patients showed that H2O2 release was reduced when proteinuric condition was improved to be in remission. Our data suggest that monocytes in SSNS with proteinuria were activated and were prepared to receive some extracellular signaling leading to protein kinase-C activation for releasing H2O2.

Abstract
The purpose of this study was to determine the antioxidant enzyme activities in renal tissues of early stage ddY mice, an animal model for primary IgA nephropathy. Eight- and 40-week-old ddY female mice and normal healthy Balb/c female mice were used in this study. The levels of Cu/Zn-SOD, Mn-SOD, and GSH-PX activities in the renal cortex were significantly higher in 40-week-old ddY mice than in Balb/c control mice of the same age; no change of catalase activity was observed. There were no significant differences in the levels of Cu/Zn-SOD, Mn-SOD, GSH-PX, and catalase activities between the ddY mice and Balb/c mice at 8 weeks of age. Urinary protein was slightly higher in 40-week-old ddY mice. IgA or C3 was deposited at low levels in the glomerular mesangial areas of 8-week-old ddY mice. Marked depositions of IgA and C3 extended from the glomerular mesangial areas to the capillary walls of 40-week-old ddY mice. Expansion of glomerular mesangial matrices and mild mesangial cell proliferation was observed in 40-week-old ddY mice. Antioxidant enzyme activities in the renal cortex were already increased in the early stage IgA nephropathy in 40-week-old ddY mice. These findings suggest that measurements of antioxidant enzyme activities in the renal cortex of 40-week-old ddY mice was useful for evaluation of the pathogenesis of renal involvement in the early stage of IgA nephropathy.

Abstract
Superoxide (O2-) production and Fc alpha R antigen expression of circulating polymorphonuclear leukocytes (PMNL) isolated from patients with IgA nephropathy (IgAN) and non-IgA mesangial proliferative glomerulonephritis (PGN) and healthy volunteers were investigated to establish their biological importance in the immunopathogenesis of mesangial proliferative glomerulonephritis. PMNL from both patient groups showed increased O2- production when stimulated with N-formyl methionyl leucyl phenylalanine (FMLP) and phorbol myristate acetate (PMA). The increased O2- generation demonstrated a positive correlation with the degree of proteinuria. Aggregated IgA caused enhanced O2- production only in patients with IgAN who also showed a significant correlation with proteinuria. Increased expression of Fc alpha R on circulating PMNL was observed in IgAN patients as determined by flow cytometric analysis. The amount of Fc alpha R on PMNL was positively correlated with O2- generation triggered with IgA aggregates. These results suggest that: 1. Circulating PMNL may potentially be participating in the pathogenesis of glomerular injury in mesangial proliferative glomerulonephritis, and 2. IgA aggregates/immune complexes may contribute to the immunopathogenesis of IgAN through augmenting the Fc alpha receptor-mediated generation of superoxide anion.

Abstract
The production of hydrogen peroxide (H2O2) by neutrophilic polymorphonuclear leukocytes (PMN) after stimulation with phorbol myristate acetate (PMA), n-formyl-l-methionyl-l-leucyl-l-phenylalanine (FMLP), aggregated human IgG, or Staphylococcus aureus was determined in 36 patients with non-insulin dependent diabetes mellitus (NIDDM). H2O2 production by PMN after stimulation was measured using flow cytometry. Thirty-six patients with NIDDM were divided into four stages as follows: 1) stage I: non-microalbuminuric stage; 2) stage II: microalbuminuric stage; 3) stage III: proteinuric stage without impairment of renal function; and 4) stage IV: proteinuric stage with impairment of renal function. H2O2 production after PMA stimulation in all stages of NIDDM patients was higher than that in healthy controls. This increase of H2O2 production by PMN was particularly observed in stage IV of NIDDM patients after stimulation. Furthermore, H2O2 production in patients in stage IV was higher than that in patients with non-diabetic disease with impairment of renal function. It appears that reactive oxygen species produced by PMN after stimulation under some conditions may play an important role in the progression of diabetic nephropathy.
