Abstract
Recent evidence has shown significant roles of mitochondria-derived vesicles (MDVs) in mitochondrial quality control (MQC) system. Under mild stress condition, MDVs are formed to carry the malfunctioned mitochondrial components, such as mitochondrial DNA (mtDNA), peptides, proteins and lipids, to be eliminated to restore normal mitochondrial structure and functions. Under severe oxidative stress condition, mitochondrial dynamics (fission/fusion) and mitophagy are predominantly activated to rescue mitochondrial structure and functions. Additionally, MDVs generation can be also triggered as the major MQC machinery to cope with unhealthy mitochondria when mitophagy is unsuccessful for eliminating the damaged mitochondria or mitochondrial fission/fusion fail to recover the mitochondrial structure and functions. This review summarizes the current knowledge on MDVs and discuss their roles in physiologic and pathophysiologic conditions. In addition, the potential clinical relevance of MDVs in therapeutics and diagnostics of kidney stone disease (KSD) are emphasized.

Abstract
Background Solute-linked carrier 26 gene family 6 (SLC26A6), which is mainly expressed in intestines and kidneys, is a multifunctional anion transporter crucial in the transport of oxalate anions. This study aimed to investigate the role of kidney SLC26A6 in urolithiasis. Methods Patients were divided into two groups: stone formers and nonstone formers. Samples were collected from patients following nephrectomy. Lentivirus with Slc26a6 (lentivirus-Slc26a6) sequence and lentivirus with siRNA-Slc26a6 (lentivirus-siRNA-Slc26a6) sequence were transfected into rats’ kidneys respectively and Slc26a6 expression was detected using Western blot and immunohistochemical analyses. After administering ethylene glycol, oxalate concentration and prevalence of stone formation between the transgenic and control groups were measured using 24-h urine analysis and Von Kossa staining, respectively. Results Immunohistochemical and Western blot analyses indicated that stone formers had a significantly higher level of expression of SLC26A6 in the kidney compared with the control group. After lentivirus infection, the urinary oxalate concentration and rate of stone formation in lentivirus-Slc26a6-tranfected rats increased remarkably, while lentivirus-siRNA-Slc26a6-transfected rats showed few crystals. Conclusion The results showed that high expression levels of renal SLC26A6 may account for kidney stone formation. Downregulating the expression of SLC26A6 in the kidney may be a potential therapeutic target to prevent or treat urolithiasis.

Abstract
PURPOSE We have recently reported lipopolysaccharide (LPS) pretreatment attenuated renal ischemia/reperfusion injury (IRI), but the exact mechanism remains to be well elucidated. It was reported that heat shock protein (Hsp) 27 was up-regulated after administration of LPS, but whether a direct link existed between Hsp27 up-regulation and LPS-induced protection against renal IRI is still unknown. METHODS Mice were exposed to IRI or sham procedure, with pretreatment of LPS or not. Quercetin, an inhibitor of Hsp27 synthesis, was used, and an RNA interference with adenovirus vector using short hairpin RNA targeting Hsp27 was developed for inhibition of Hsp27 in mice. In addition, mice trans-infected with adenovirus vector encoding Hsp27 were used to testify the role of Hsp27 overexpression in LPS-induced renoprotection. Renal function, histological damage, inflammatory reaction, oxidative stress and apoptosis indices were measured. Western blot analysis was used to detect expression of Hsp27. RESULTS We found LPS pretreatment stimulated renal up-regulation of Hsp27 and reduced renal IRI proven by less renal dysfunction, histological damage, inflammatory reaction, oxidative stress and apoptosis. It was observed that inhibition of Hsp27 synthesis by Quercetin abolished LPS-induced renoprotective effects. After renal knockdown of Hsp27, LPS-induced tolerance against renal IRI was largely removed. Mice with Hsp27 overexpression showed significantly improved renal function after IRI and LPS combined with Hsp27 overexpression had a synergistic effect on protection against renal IRI. CONCLUSION Administration of LPS produces protective effects against renal IRI via Hsp27 up-regulation. Preconditional Hsp27 up-regulation might have a great potential for the treatment of renal IRI via ameliorating apoptosis.

Abstract
Oxalates stimulate alterations in renal epithelial cells and thereby induce calcium oxalate (CaOx) stone formation. Bacillus subtilis YvrK gene encodes for oxalate decarboxylase (OxdC) which degrades oxalate to formate and CO2. The present work is aimed to clone the oxdC gene in a mammalian expression vector pcDNA and transfect into Human Embryonic Kidney 293 (HEK293) cells and evaluate the oxdC expression, cell survival rate and oxalate degrading efficiency. The results indicate cell survival rate of HEK293/pcDNAOXDC cells pre-incubated with oxalate was enhanced by 28%. HEK293/pcDNAOXDC cells expressing OxdC treated with oxalate, significantly restored antioxidant activity, mitochondrial membrane potential and intracellular reactive oxygen species (ROS) generation compared with HEK293/pcDNA. Apoptotic marker caspase 3 downregulation illustrates HEK293/pcDNAOXDC cells were able to survive under oxalate-mediated oxidative stress. The findings suggest HEK293 cells expressing oxdC capable of degrading oxalate protect cells from oxidative damage and thus serve as a therapeutic option for prevention of CaOx stone disease.

Antioxidant Pre-Treatment Reduces the Toxic Effects of Oxalate on Renal Epithelial Cells in a Cell Culture Model of Urolithiasis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14010109. [PMID: 28125004 PMCID: PMC5295359 DOI: 10.3390/ijerph14010109] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2016] [Revised: 01/10/2017] [Accepted: 01/17/2017] [Indexed: 12/26/2022]
Abstract
Urolithiasis is characterized by the formation and retention of solid crystals within the urinary tract. Kidney stones are mostly composed of calcium oxalate, which predominantly generates free radicals that are toxic to renal tubular cells. The aim of the study is to explore possible effects of antioxidant pre-treatment on inhibition of oxidative stress. Three cell lines were used as in vitro model of urolithiasis: MDCK I, MDCK II and LLC-PK1. Oxidative stress was induced by exposure of cells to sodium oxalate in concentration of 8 mM. In order to prevent oxidative stress, cells were pre-treated with three different concentrations of l-arginine and vitamin E. Oxidative stress was evaluated by determining the expression of superoxide dismutase (SOD), osteopontin (OPN), and by the concentration of glutathione (GSH). In all three cell lines, pre-treatment of antioxidants increased cell survival. Positive correlation of SOD and OPN expression as well as GSH concentration was observed in all groups of cells. Our results indicate that an antioxidant pre-treatment with l-arginine and vitamin E is able to hamper oxalate-induced oxidative stress in kidney epithelial cells and as such could play a role in prevention of urolithiasis.

Effects of calcium oxalate monohydrate crystals on expression and function of tight junction of renal tubular epithelial cells. J Transl Med 2011; 91:97-105.

Abstract
Tight junction has a crucial role in regulating paracellular transports (as a barrier) and in separating apical from basolateral compartments to maintain cell polarity (as a fence). Tight junction can be disrupted by various stimuli, including oxidative stress, pathogens and proinflammatory cytokines. However, association of defective tight junction with kidney stone pathogenesis remains unknown. We therefore examined whether calcium oxalate monohydrate (COM) crystals, which are the major crystalline composition in kidney stones, have any effects on expression and function of tight junction of polarized renal tubular epithelial cells. Western blot analysis revealed marked decrease in levels of occludin and zonula occludens-1 (ZO-1) in COM-treated polarized Madin-Darby canine kidney (MDCK) cells. Immunofluorescence staining revealed not only the decline of these tight junction proteins but also their redistribution and dissociation in COM-treated cells. Additionally, transepithelial resistance was significantly decreased, indicating impaired tight junction barrier and increased paracellular permeability in COM-treated cells. Subcellular fractionation followed by western blot analysis of Na(+)/K(+)-ATPase-α1 revealed that this basolateral membrane marker was also detectable in apical membrane fraction of COM-treated cells, but not in apical membrane fraction of control cells. Immunofluorescence study confirmed the translocation of Na(+)/K(+)-ATPase-α1 (from basolateral to apical membranes) in COM-treated cells, indicating impaired fence function of the tight junction. Moreover, dihydrorhodamine assay using flow cytometry revealed the significantly higher level of hydrogen peroxide in the COM-treated cells. These data provide the first evidence to demonstrate decreased expression and defective barrier and fence functions of the tight junction of renal tubular epithelial cells exposed to COM crystals that may be fundamental for subsequent renal tubulointerstitial injury, which in turn enhances the stone pathogenesis.

Abstract
Calcium oxalate is one of the main constituents of kidney stones and has a proved deleterious effect on renal cells that is mediated by oxidative stress. However, the subcellular source of this oxidative stress, and whether it is extending to the extracellular space or not, is still disputed. Therefore, an electrochemical superoxide biosensor was constructed, positioned above A6 renal cells, and used to measure in real-time the extracellular oxidative burst following addition of calcium oxalate crystals. It was observed that A6 cells do secrete superoxide into their extracellular space in few minutes after encountering calcium oxalate crystals. The amount of released superoxide peaks at about 20 min. Superoxide is cleared away from the extracellular space after approximately 3h. Superoxide secretion depends on the presence of superoxide-scavenging enzyme superoxide dismutase, the age of the cells, the amount of calcium oxalate crystals, and the temperature. Moreover, the effect of calcium oxalate crystals was mimicked by phorbol 12-myristate 13-acetate. The developed sensing system can be a useful tool for biologists investigating nephrolithiasis at cellular level.
